Vaccine hesitancy primarily consists of confidence, complacency, and convenience, including geographical accessibility. However, few studies in developed countries have focused on the association between geographical accessibility to vaccination services and vaccination status and previous studies have shown conflicting results. This cross-sectional study aimed to clarify the association between the number of medical facilities within a 15-minute driving distance from the place of residence and influenza vaccination status, using a large nationwide internet survey in Japan (n = 27,440). Postal codes were used to determine participants' place of residence and the number of medical facilities within a 15-minute drive was calculated using geographic information system data. Participants were classified into quartiles based on the number of medical facilities nearby. They reported their influenza vaccination status over the past year. Modified Poisson regression analysis was conducted with influenza vaccination status as the dependent variable and the number of medical facilities nearby as the independent variable, adjusted for covariates stratified by age (under 65 years: or 65 years and older). Among participants aged 65 years and older, those with fewer medical facilities within a 15-minute drive of their place of residence were significantly less likely to have received an influenza vaccination than those with more medical facilities nearby (prevalence ratio in Q1 relative to Q4: 0.93, 95% confidence interval 0.87-0.99). In contrast, no association was observed among participants aged under 65 years. Geographical accessibility to vaccination services may influence vaccine hesitancy among older adults in Japan, a developed country.

IMPORTANCE: Although evaluation of geographic area inequities in vaccination is crucial to identify areas that need community-based interventions, knowledge of disparities in human papillomavirus (HPV) vaccination uptake remains limited in Japan. OBJECTIVE: To investigate the association of female cumulative HPV vaccination uptake with neighborhood-based socioeconomic status and access indicators in Osaka City, Japan. DESIGN, SETTING, AND PARTICIPANTS: This population-based, cross-sectional study included HPV vaccination data for fiscal year (April 1 to March 31) 2013 to fiscal year 2022 provided by Osaka City. The study population comprised the total number of girls eligible for HPV vaccination born between fiscal years 1997 and 2010. EXPOSURE: The area deprivation index (ADI) was used as a neighborhood-based socioeconomic status indicator, and the number of medical facilities providing HPV vaccination within a 500-m range of a representative point in each geographic area was used as an access indicator. MAIN OUTCOMES AND MEASURES: The primary outcome was cumulative uptake, defined as the cumulative number of girls receiving at least 1 dose and those completing all doses (3 doses until March 2023), by neighborhood ADI and access indicators. A Poisson regression model with robust variance was applied to assess the association of neighborhood-level indicators with cumulative HPV vaccination uptake. RESULTS: In Osaka City, 185 373 girls (median [IQR] age at vaccination, 16 [14-19] years) were eligible for HPV vaccination, of whom 18 688 (10.1%) received at least 1 dose of HPV vaccine. Compared with girls living in areas with the most deprivation (2539 of 28 078 [9.0%]), those living in areas with the least deprivation (4889 of 42 170 girls [11.6%]) had a greater cumulative HPV vaccination uptake (prevalence ratio [PR], 1.25; 95% CI, 1.16-1.34). In addition, compared with girls living in areas with low medical facility access (5128 of 55 055 [9.3%]), those residing in high-access areas (5862 of 54 740 [10.7%]) had a greater cumulative vaccination uptake (PR, 1.09; 95% CI, 1.03-1.16). Cumulative HPV vaccination was significantly associated with ADI in routine vaccination (least vs most deprivation: PR, 1.46; 95% CI, 1.33-1.61) but not in catch-up vaccination (least vs most deprivation: PR, 1.01; 95% CI, 0.92-1.11). CONCLUSIONS AND RELEVANCE: In this cross-sectional study of area deprivation, vaccination access, and HPV vaccination status, higher socioeconomic status and higher medical facility access were associated with higher cumulative HPV vaccination uptake. These findings suggest that further strategies, including a socioecologic approach, are needed to increase HPV vaccination and reduce disparities in uptake.

BACKGROUND: Few studies have shown that relatively younger children and adolescents (those born later in the same school year) were less likely to engage in physical activity in a phenomenon termed the relative age effect. Although these studies mainly targeted elementary and middle school students, no study has reported on the relative age effect on physical activity in ordinary high school students. Moreover, the relative age effect on sedentary behavior might show an opposite association with physical activity. Therefore, we aimed to clarify the relative age effects on physical activity and sedentary behavior across different school stages in Japanese children and adolescents. METHODS: A cross-sectional questionnaire survey was conducted with 21,491 children and adolescents (elementary, middle, and high school students aged 10-18 years) in various Japanese regions from January 2018 to July 2019. Overall, 18,281 children and adolescents (10,299 boys and 7,982 girls) were finally included in our analysis. Data on the birth month, frequency and duration of their physical activity (vigorous, moderate, and moderate-to-vigorous intensity), and sedentary behavior (weekday and weekend total sedentary time, television viewing, playing video games, and Internet use) were obtained. We utilized two-part model regression analyses. Statistically significant association with birth month indicated that a relative age effect was observed. RESULTS: The relatively younger individuals were less likely to engage in physical activity (especially vigorous physical activity (VPA)); this association was observed in middle and high school students. Conversely, the relatively younger boys spent more time during weekends with sedentary behaviors and Internet use. Based on school stage, the relative age effect on VPA time was observed in middle school boys (average margin effect (AME) = -0.74, p < 0.01) and high school students (boys: AME = -0.69, p < 0.01; girls: AME = -0.53, p < 0.05). The relative age effect on sedentary behavior was observed during weekends with sedentary behaviors (AME = 3.55, p < 0.01), playing video games (AME = 0.72, p < 0.05) and Internet use (AME = 2.46, p < 0.01) for male high school students and on television viewing (AME = 1.12, p < 0.05) for female middle school students. CONCLUSION: The relative age effect on physical activity can persist after middle school, and the relatively younger individuals are more likely to replace physical activity with sedentary behavior.

To control the COVID-19 epidemic, the Japanese government and the local governments have repeatedly implemented non-pharmaceutical interventions (NPIs) throughout 2020-2022. Using Bayesian state-space mediation models, we examined the effect of repeated NPIs on infection spread mitigation, mediated by human mobility changes in each prefecture during three epidemic phases: from April 1, 2020 to February 28, 2021; from March 1, 2021 to December 16, 2021; and from December 17, 2021 to December 31, 2022. In the first phase, controlling downtown populations at nighttime was effective in mitigating the infection spread in almost all prefectures. In the second and third phases, the effect was not clear, especially in metropolitan prefectures. Controlling visitors from the central prefectures of metropolitan areas was effective in mitigating infection spread in the surrounding prefectures during all phases. These results suggest that the local spread of infection can be mitigated by focusing on nighttime human mobility control in downtown areas before the epidemic spreads widely and transmission routes become more diverse, and that the geospatial spread of infection can be prevented by controlling the flows of people from large cities to other areas.

BACKGROUND AND AIMS: Night-shift work disturbs sleep and is associated with poor health conditions among workers. We aimed to investigate the association between night-shift work and gambling among workers and the association between night-shift work and problem gambling in working and gambling participants. METHODS: This cross-sectional study used data from an online survey conducted between February 6 and 27, 2023 in Japan. A total of 21,134 workers participated in this study, including 9,739 respondents who had gambled in the past year. We estimated the association between night-shift work and gambling among workers and the association between night-shift work and problem gambling among those who gambled at the survey. We defined problem gambling as a score ≥ 8 on the Problem Gambling Severity Index. All estimates were weighted using a nationally representative survey in Japan. We fitted multivariable weighted logistic regression models after adjusting for 14 confounders. RESULTS: The weighted prevalence of gambling among non-night and night-shift workers was 42.1 % and 55.4 %, respectively. When focusing on workers gambling in the survey, the prevalence of problem gambling among non-night and night-shift workers was 8.8 % and 24.2 %, respectively. The weighted multivariable logistic regression analyses showed that night-shift work was associated with gambling participation among workers (adjusted odds ratio [aOR], 1.39, 95 % confidence interval [CI] 1.25-1.53, p < 0.001). In addition, night-shift work was associated with problem gambling among those who gambled (aOR 1.94, 95 % CI 1.57-2.40, p < 0.001). CONCLUSIONS: Night-shift work was associated with gambling among workers and with problem gambling among those who gambled.

OBJECTIVES: Some studies reported a relationship between life-space mobility (LSM) and frailty assessed by physical aspects; however, a more comprehensive discussion of frailty is underdeveloped. In addition, previous studies have focused only on older Euro-American people. Therefore, we aimed to examine LSM-frailty relationships in community-dwelling older Japanese persons using physical and comprehensive frailty indices. DESIGN: A cross-sectional study. SETTING AND PARTICIPANTS: We used the data of 8898 older adults from a baseline survey of the Kyoto-Kameoka Study in Japan. METHODS: The validated life-space assessment (LSA) was used to evaluate LSM and categorized it into quartiles. Two validated indices were used to evaluate frailty: the Kihon Checklist (KCL) and the simple Frailty Screening Index (FSI). Multivariable logistic regression was used to determine the relationships between LSM scores and frailty. RESULTS: The mean age (SD) of the participants was 73.4 (6.3) years, and 53.3% were women. The mean LSM score of the study participants was 53.0. The prevalence of frailty by KCL and FSI was 40.7% and 16.8%, respectively. Significant differences between LSM score and frailty prevalence were observed [KCL: Q1, reference; Q2, odds ratio (OR) 0.53, 95% CI 0.45-0.62; Q3, OR 0.30, 95% CI 0.25-0.35; Q4: OR 0.22, 95% CI 0.18-0.26, P for trend <.001; FSI: Q1, reference; Q2, OR 0.57, 95% CI 0.48-0.68; Q3: OR 0.38, 95% CI 0.31-0.46; Q4: OR 0.35, 95% CI 0.28-0.42, P for trend <.001]. Similar results were observed when LSM scores were examined at 10-point intervals, with LSM and frailty exhibiting an L-shaped relationship. The LSM score dose-response curve at which the OR for frailty plateaued among older individuals was approximately 81-90 score. CONCLUSIONS AND IMPLICATIONS: LSM score and frailty prevalence exhibited L-shaped relationships in community-dwelling older persons. This study's findings provide useful data for setting LSM targets for preventing frailty in community-dwelling older persons.

Abstract Studies have shown that migrants and ethnic minority groups were unevenly affected by the COVID-19 pandemic, with most evidence coming from Western countries. This study explores the experience of migrants in Japan during the COVID-19 pandemic, examining the association between social environment (i.e., population density, neighborhood deprivation, ethnic density, and social networks) and both COVID-19 infections and vaccination uptake. Data from two nationwide online surveys conducted in 2021 and 2023 were used to analyze these associations during the middle and waning stages of the pandemic. We found that migrants in Japan were more vulnerable to COVID-19 infection but were more receptive to vaccination compared to Japanese nationals. However, not all migrant groups experienced the same outcomes. The effects of social environmental factors on infection and vaccination acceptance were complex and could change, as the pandemic progressed. Environmental factors such as neighborhood population density were not necessarily determinants of COVID-19 infection. More social contacts with Japanese nationals could mitigate vaccination hesitancy, while larger social ties with co-national in the neighborhoods could lead to a higher infection rate. In anticipation of future pandemics, customized programs should be prepared to address the unique healthcare needs of migrants.

BACKGROUND: The decline in measles vaccination coverage is a global concern. In Japan, coverage of the first-dose of measles vaccine, which had exceeded the target of 95.0% since fiscal year (FY) 2010, fell to 93.5% in FY 2021. Vaccination coverage increased to 95.4% in FY 2022 but varied by municipality. Few studies have focused on regional disparities in measles vaccination coverage. This study aimed to clarify the regional disparities in measles vaccination coverage by municipality in Japan and their associated factors. METHODS: In this ecological study, the measles vaccination coverage in FY 2022; population density; area deprivation index (ADI, an indicator of socioeconomic status); proportion of foreign nationals, single-father households, single-mother households, and mothers aged ≥30 years; and number of medical facilities, pediatricians, and non-pediatric medical doctors in 1,698 municipalities were extracted from Japanese government statistics. Negative binomial regression was performed with the number of children vaccinated against measles as the dependent variable, number of children eligible for measles vaccination as the offset term, and other factors as independent variables. RESULTS: Vaccination coverage was less than 95.0% in 54.3% of municipalities. Vaccination coverage was significantly positively associated with population density and negatively associated with the proportion of single-father households, mothers aged ≥30 years, and the ADI (incidence rate ratio [IRR]: 1.004, 0.976, 0.999, 0.970, respectively). CONCLUSION: This study showed regional disparities in measles vaccination coverage in Japan. Single-father households, age of mothers, and socioeconomic status may be key factors when municipalities consider strategies to improve vaccination coverage.

OBJECTIVES: Changing the mode of commuting from nonactive by car or motorcycle to active by walking, cycling, or public transport is expected to benefit health. However, the proportion of nonactive commuters who can change their commute mode to active forms remains unclear. The aim of this study was to determine the proportions of nonactive commuters and of those who can change their commute mode to an active form in various regions in Japan. METHODS: In this descriptive study, data were used from an online survey conducted from April to May 2021. Participants included 3,000 adults (20 to 79 years), who were registered with an online survey company. Workers were asked their means of transportation to work and commuting time. Workers using a car or motorcycle for more than 1 minute for commuting were defined as nonactive commuters, and the others were defined as active commuters. Then, nonactive commuters were asked about the possibility of changing their commute mode to active commuting (0%-100%, 11 options in 10% increments). The possibility of change was classified into four groups, i.e., impossible (0%), difficult (10%-40%), probably possible (50%-90%), and possible (100%). The proportions of nonactive commuters and nonactive commuters who can transition to active commuting were described by region. RESULTS: A total of 2,683 participants answered the survey, including 1,647 workers, of whom 1,551 were commuters. The nonactive commuters accounted for 41.4% of commuters overall. The proportion of nonactive commuters was higher in rural than in urban regions. The proportion of nonactive commuters who could change their commute mode was 32.9% of the nonactive commuters or 12.8% of all workers. Among the nonactive commuters, the proportion who could change their commute mode was higher in urban than in rural regions. Of the total workers, the proportion of nonactive commuters who could change their commute mode was higher in rural regions. CONCLUSION: Nonactive commuters accounted for 41.4% of all commuters. The proportion of nonactive commuters who could change their commute mode among nonactive commuters was higher in urban regions. However, in rural regions, as the proportion of nonactive commuters was high, the proportion of nonactive commuters who could change their commute mode among total workers was also high. These results suggest that some of nonactive commuters can change their commute mode from nonactive to active commuting, in rural as well as in urban regions.

BACKGROUND: It has been pointed out that eye-level greenery streetscape promotes leisure walking which is known to be a health -positive physical activity. Most previous studies have focused on the total amount of greenery in the eye-level streetscape to investigate its association with walking behaviour. While it is acknowledged that taller trees contribute to greener environments, providing enhanced physical and psychological comfort compared to lawns and shrubs, the examination of streetscape metrics specifically focused on greenery height remains largely unexplored. Therefore, this study examined the relationship between objective indicators of street greenery categorized by height from a pedestrian viewpoint and leisure walking time. METHODS: We created streetscape indices of street greenery using Google Street View Images at 50-m intervals in an urban area in Sendai City, Japan. The indices were classified into four ranges according to the latitude of the virtual hemisphere centred on the viewer. We then investigated their relationship to self-reported leisure walking. RESULTS: Positive associations were identified between the street greenery in higher positions and leisure walking time, while there was no significant association between the greenery in lower positions. CONCLUSION: The findings indicated that streets with rich greenery in high positions may promote residents' leisure walking, indicating that greenery in higher positions contributes to thermally comfortable and aesthetic streetscapes, thus promoting leisure walking. Increasing the amount of greenery in higher positions may encourage residents to increase the time spent leisure walking.

There is evidence that higher street connectivity and availability of destinations can support walking behavior. However, the availability of data and comparability between previous studies remain a challenge. Based on a large Canadian adult sample, this study examined the associations between street layout and walking behaviors and explored whether objectively measured destinations may mediate these relationships. This study used data from 12,378 adults from Alberta's Tomorrow Project (ATP), a prospective cohort study conducted in Alberta, Canada. Walking behaviors were obtained by questionnaires. Street layout and destination measures were calculated objectively. Covariate-adjusted multivariate linear models estimated the associations between the space syntax street integration and duration of transport and leisure walking. The mediation effects of the availability of destinations in these associations were tested by the structural equation modelling. Street integration was significantly positively associated with transportation walking (b=0.01, 95% CI 0.00, 0.01, p = 0.01) (indirect effect). The availability of destinations partially mediated this association. Using the natural movement theory in space syntax, our study provides insights into using street layouts as a primary measure to (re)design the built environment to support walking.

Abstract The design and quality of the neighbourhood built environment can encourage health-supportive behaviours and support cardiometabolic health. However, despite the relationships between demographic and behavioural risk factors of metabolic syndrome being investigated by many studies, only some studies have directly estimated the associations between the built environment and metabolic syndrome. Using data from Canada, we examined the associations between the neighbourhood built environment and metabolic syndrome. Data from Alberta’s Tomorrow Project participants, conducted in Alberta, Canada, was used (n = 6718). Metabolic syndrome was defined as the presence of at least three clinical risk factors among lipid levels, blood pressure, and waist circumference. The normalised difference vegetation index was used to quantify the greenness of each participant’s neighbourhood. Built attributes of participants’ neighbourhoods associated with supporting physical activity, including dwelling density, intersection density, and the number of points of interest, were obtained via the Canadian Urban Environmental Health Research Consortium. Increases in the number of points of interest and total active living environment-friendliness of the neighbourhood were associated with having fewer metabolic syndrome risk factors (b = −0.11, 95% CI −0.16, −0.07 and b = −0.03, 95% CI −0.05, −0.01, respectively) and lower odds of metabolic syndrome (OR = 0.89, 95% CI 0.84, 0.094 and OR = 0.97, 95% CI 0.95, 0.99, respectively). Furthermore, higher dwelling density was associated with having fewer metabolic syndrome risk factors (b = −0.05, 95% CI −0.09, −0.01). Our findings highlight the importance of urban design to prevent and potentially manage metabolic syndrome and improve population health.

Accumulating evidence suggests that the built environment may be associated with cardiovascular disease via its influence on health behaviours. The aim of this study was to estimate the associations between traditional and novel neighbourhood built environment metrics and clinically assessed cardio-metabolic risk factors among a sample of adults in Canada. A total of 7171 participants from Albertas Tomorrow Project living in Alberta, Canada, were included. Cardio-metabolic risk factors were clinically measured. Two composite built environment metrics of traditional walkability and space syntax walkability were calculated. Among men, space syntax walkability was negatively associated with systolic and diastolic blood pressure (b = -0.87, 95% CI -1.43, -0.31 and b = -0.45, 95% CI -0.86, -0.04, respectively). Space syntax walkability was also associated with lower odds of overweight/obese among women and men (OR = 0.93, 95% CI 0.87, 0.99 and OR = 0.88, 95% CI 0.79, 0.97, respectively). No significant associations were observed between traditional walkability and cardio-metabolic outcomes. This study showed that the novel built environment metric based on the space syntax theory was associated with some cardio-metabolic risk factors.

A causal relationship between mesothelioma and occupational asbestos exposure is well known, while some studies have shown a relationship to non-occupational exposures. The aim of this study was to quantify the risk of mesothelioma death associated with neighborhood asbestos exposure due to a large-scale asbestos-cement (AC) plant in Amagasaki, Japan, adjusting properly risk factors including occupational exposures. We conducted a nested case-control study in which a fixed population of 143,929 residents who had been living in Amagasaki City between 1975 and 2002 were followed from 2002 to 2015. All 133 cases and 403 matched controls were interviewed about their occupational, domestic, household, and neighborhood asbestos exposures. Odds ratios (ORs) for mesothelioma death associated with the neighborhood exposure were estimated by a conditional logistic-regression model. For quantitative assessments for neighborhood exposure, we adopted cumulative indices for individuals' residential histories at each residence-specific asbestos concentration multiplied by the duration during the potential exposure period of 1957-1975 (crocidolite). We observed an increasing, dose-dependent risk of mesothelioma death associated with neighborhood exposure, demonstrating that ORs in the highest quintile category were 21.4 (95% confidence interval [CI] 5.8-79.2) for all, 23.7 (95% CI 3.8-147.2) for males, and 26.0 (95% CI 2.8-237.5) for females compared to the lowest quintile, respectively. A quantitative assessment for risk of mesothelioma deaths, adjusting for occupational and non-occupational exposures separately, showed a dose-dependent association with neighborhood exposure and no substantial gender differences in magnitude.

We aimed to determine whether neighborhood socioeconomic characteristics are associated with the coronavirus disease 2019 (COVID-19) incidence in elementary school children and, if so, the associated characteristics. We obtained data on the number of infected children from 282 public elementary schools and the socioeconomic characteristics of each school district in Osaka City, Japan. We examined associations between these variables through negative binomial regression analyses. The proportion of employment in the wholesale and retail trade industry and the college graduation rate were significantly positively and negatively associated, respectively, with the total number of COVID-19-infected children. It was discovered that percentages of employment in the accommodation and food service industries in Wave 2, wholesale and retail trade industries after Wave 3, and healthcare and social assistance industries in Wave 5 were significantly positively associated with the number of infected children; likewise, the college graduation rate in Wave 5 was significantly negatively associated with the number of infected children. Our findings provide insight into the relevant and important areas of focus for public health policymakers and practitioners to ensure reduced disparities in COVID-19 infection rates.

Worldwide, research based on geographic information of official statistical data, including cancer registries, is utilized for cancer control and public health policies. The National Cancer Registry of Japan was launched in 2016, making it possible to use data on cancer incidence systematically. Given the nature of this comprehensive survey, the usefulness of the National Cancer Registry would be further enhanced when it is utilized at small-regional levels, such as in municipalities or even smaller geographical units. It is essential to maintain a balance between privacy protection and data usability. Currently, the national and prefectural councils determine the availability of the data from the National Cancer Registry at the small-regional level on an individual application basis. Under this framework, use of the data is often restricted or declined. This paper showcases three model countries where geographic information obtained from cancer registry data are widely utilized: the United States, Canada, and the United Kingdom. It further discusses measures to ensure that data are effectively used, without compromising data privacy. In the three countries, data-providing systems have been established to compile the necessary data from the cancer registry and other linked databases, in accordance with the purpose of use. The relationships between healthcare access and various outcomes are elaborately examined at the small-regional level. In Japan, similar utilization of data has not been fully implemented, and there remain many hurdles to the application of the data use. For the National Cancer Registry to promote research and further enhance cancer control, it is necessary to establish a system that enables effective and safe utilization of the data from the National Cancer Registry, including linkage with other data and on-site use.

Little is known about information seeking and its influence on preventive behaviors among immigrants in Japan, despite their vulnerabilities during the coronavirus disease 2019 (COVID-19) pandemic. This study investigated information seeking about COVID-19, and examined differences with compliance with preventive measures between immigrants and the host population in Japan based on an Internet survey conducted in October 2021. We used chi-squared tests to determine the difference in information seeking and preventive behaviors between the two groups, and Poisson regression with robust standard errors to examine the association between information seeking and compliance with preventive measures. Our results show that, although the overall tendencies of information seeking and the preventive behaviors of immigrants were similar to those of the Japanese, significant differences were identified in some behavior: immigrants were more likely to acquire COVID-19 information from social networking services (SNS) and official websites in Japan, and maintain physical distance and ventilation than Japanese locals. Furthermore, immigrants’ sources of information diversified according to their sociodemographic characteristics (e.g., educational level, Japanese language skills, length of residence in Japan, and country or region of origin). Additionally, the effects of information seeking on preventive actions against COVID-19 differed according to the information sources; some information sources (e.g., SNS) had different impacts on preventive behaviors between immigrants and Japanese locals. Obtaining information from traditional media and Japanese official websites increases engagement with all five preventive measures among immigrants and four measures among the Japanese. The study highlights the importance of customized health policies for immigrants according to their behavioral tendencies.

BACKGROUND: Inequalities in opportunities for primary lung cancer surgery due to socioeconomic status exist. We investigated whether socioeconomic inequalities exist in net survival after curative intent surgery at a tertiary university hospital, in Japan. METHODS: Data from the hospital-based cancer registry on primary lung cancer patients who received lung resection between 2010 and 2018 were linked to the surgical dataset. An area deprivation index, calculated from small area statistics and ranked into tertiles based on Japan-wide distribution, was linked with the patient's address as a proxy measure for individual socioeconomic status. We estimated net survival of up to 5 years by deprivation tertiles. Socioeconomic inequalities in cancer survival were analyzed using an excess hazard model. RESULTS: Of the 1039 patient-sample, advanced stage (Stage IIIA+) was more prevalent in the most deprived group (28.1%) than the least deprived group (18.0%). The 5-year net survival rates (95% confidence interval) from the least to the most deprived tertiles were 82.1% (76.2-86.6), 77.6% (70.8-83.0) and 71.4% (62.7-78.4), respectively. The sex- and age-adjusted excess hazard ratio of 5-year death was significantly higher in the most deprived group than the least deprived (excess hazard ratio = 1.64, 95% confidence interval: 1.09-2.47). The hazard ratio reduced toward null after additionally accounting for disease stage, suggesting that the advanced stage may explain the poor prognosis among the deprived group. CONCLUSION: There was socioeconomic inequality in the net survival of patients who received curative intent surgery for primary lung cancer. The lower socioeconomic status group might be less likely to receive early curative surgery.

Despite regional differences in residents' physical activity, large-scale data that account for urban characteristics are limited. This study described the association between the composition of main transportation modes used in each city and residents' average walking time. An online survey was conducted in December 2021 among residents of 70 cities where the 2015 National Person Trip Survey was conducted, and 28,449 people were included in the analysis (50.5% male, 49.6±15.6 years old). The percentage of rail use correlated most strongly positively with average total walking time, while that of car use (self-driving) correlated strongly negatively with average walking time for walking, commuting, and shopping.

BACKGROUND: Social contact data in Japan have not been updated since 2011. The main objectives of this study are to report on newly collected social contact data, to study mixing patterns in the context of the COVID-19 pandemic, and to compare the contact patterns during and after mass events like the 2020 Olympic Games, which were held in 2021. METHODS: We compared the number of contacts per day during and after the Olympic Games and on weekdays and weekends; we also compared them with a pre-COVID-19 pandemic social contact study in Japan. Contact matrices consisting of the age-specific average number of contacted persons recorded per day were obtained from the survey data. Reciprocity at the population level was achieved by using a weighted average. RESULTS: The median number of contacts per day was 3 (interquartile range (IQR) = 1-6). The occurrence of the Olympic Games and the temporal source of data (weekday or weekend) did not change the results substantially. All three matrices derived from this survey showed age-specific assortative mixing patterns like the previous social contact survey. CONCLUSIONS: The frequency of social contact in Japan did not change substantially during the Tokyo Olympic Games. However, the baseline frequency of social mixing declined vs those collected in 2011.

Recently, various neighborhood indicators have been used to examine geographical variations in the perceptions and behaviors of urban residents in relation to the physical forms of their neighborhoods.However, the characteristics of a streetscape as a comprehensive neighborhood environment, which can only be determined by combining such indicators, have not been examined. Therefore, in this study, neighborhoods in the Sendai metropolitan area, Japan, were classified based on several urban morphological indicators to obtain a typology of Japanese residential areas in terms of the neighborhood physical environment. It was then confirmed that the various subjective evaluations of residential areas obtained from the social survey data differed significantly between the area typologies, which was also observed when controlling for individual attributes. The results revealed that the physical form of the neighborhood is associated with neighborhood liveability;in particular, a type found around city centers distinguished from other areas by its high density, connectivity, and accessibility is strongly associated with positive evaluations of the area in most aspects.

BACKGROUND: After the first-round (Preliminary Baseline Survey) ultrasound-based examination for thyroid cancer in response to the accident at the Fukushima Daiichi Nuclear Power Plant in 2011, two rounds of surveys (Full-scale Survey) have been carried out in Fukushima Prefecture. Using the data from these surveys, the geographical distribution of thyroid cancer incidence over 6 or 7 years after the disaster was examined. METHODS: Children and adolescents who underwent the ultrasound-based examinations in the second- and/or third-round (Full-scale) survey in addition to the first-round survey were included. With a discrete survival model, we computed age, sex, and body mass index standardized incidence ratios (SIRs) for municipalities. Then, we employed spatial statistics to assess geographic clustering tendency in SIRs and Poisson regression to assess the association of SIRs with the municipal average absorbed dose to the thyroid gland at the 59-municipality level. RESULTS: Throughout the second- and third-round surveys, 99 thyroid cancer cases were diagnosed in the study population of 252,502 individuals. Both flexibly shaped spatial scan statistics and maximized excess events test did not detect statistically significant spatial clustering (P = 0.17 and 0.54, respectively). Poisson regression showed no significant dose-response relationship: the estimated relative risks of lowest, middle-low, middle-high, and highest areas were 1.16 (95% confidence interval [CI], 0.52-2.59), 0.55 (95% CI, 0.31-0.97), 1.05 (95% CI, 0.79-1.40), and 1.24 (95% CI, 0.89-1.74). CONCLUSION: There was no statistical support for geographic clustering or regional association with radiation dose measures of the thyroid cancer incidence in the cohort followed up to the third-round survey (fiscal years 2016-2017) in Fukushima Prefecture.

Understanding the correlates of sedentary behavior among children is essential in developing effective interventions to reduce sitting time in this vulnerable population. This study aimed to identify correlates of domain-specific sedentary behaviors and objectively assessed sedentary time among a sample of children in Japan. Data from 343 children (aged 6-12 years) living in Japan were used. Domain-specific sedentary behaviors were assessed using a questionnaire. Total sedentary time was estimated using hip-worn accelerometers. Twenty-two potential correlates across five categories (parental characteristics, household indoor environment, residential neighborhood environment, school environment, and school neighborhood environment) were included. Multivariable linear regression models were used to identify correlates of domain-specific sedentary behaviors and objectively assessed sedentary time. Eight correlates were significantly associated with children's domain-specific sedentary behaviors: mother's and father's age, mother's educational level, having a video/DVD recorder/player, having a video console, having a TV one's own room, home's Walk Score®, and pedestrian/cycling safety. No significant associations were found between potential correlates and accelerometer-based total sedentary time. These findings highlight that strategies to reduce children's sedentary time should consider the context of these behaviors. For example, urban design attributes such as perceived pedestrian and cycling safety can be improved to reduce children's car sitting time.

BACKGROUND: Cancer survival varies by socioeconomic status in Japan. We examined the extent to which survival disparities are explained by factors relevant to cancer control measures (promoting early-stage detection, standardizing treatment, and centralizing patients to government-accredited cancer hospitals [ACHs]). METHODS: From the Osaka Cancer Registry, patients diagnosed with solid malignant tumors during 2005-2014 and aged 15-84 years (N = 376,077) were classified into quartiles using the Area Deprivation Index (ADI). Trends in inequalities were assessed for potentially associated factors: early-stage detection, treatment modality, and utilization of ACH (for first contact/diagnosis/treatment). 3-year all-cause survival was computed by the ADI quartile. Multivariable Cox regression models were used to assess survival disparities and their trends through a series of adjustment for the potentially associated factors. RESULTS: During 2005-2014, the most deprived ADI quartile had lower rates than the least deprived quartile for early-stage detection (42.6% vs. 48.7%); receipt of surgery (58.1% vs. 64.1%); and utilization of ACH (83.5% vs. 88.4%). While rate differences decreased for receipt of surgery and utilization of ACH (Annual Percent Change = -3.2 and - 11.9, respectively) over time, it remained unchanged for early-stage detection. During 2012-2014, the most deprived ADI quartile had lower 3-year survival than the least deprived (59.0% vs. 69.4%) and higher mortality (Hazard Ratio [HR] = 1.32, adjusted for case-mix): this attenuated with additional adjustment for stage at diagnosis (HR = 1.23); treatment modality (HR = 1.20); and utilization of ACH (HR = 1.19) CONCLUSIONS: Despite improvements in equalizing access to quality cancer care during 2005-2014, survival disparities remained. Interventions to reduce inequalities in early-stage detection could ameliorate such gaps.

Abstract Research indicates that integration contributes to maintaining health among migrants, yet little is known about the association between integration and vaccination acceptance. This study aimed to explore COVID-19 vaccine intention and acceptance, and the association between integration and vaccine hesitancy among migrants in Japan. We conducted an internet survey among migrants in Japan from October 5 to October 14, 2021. Among 1,455 participants, 11.6% reported hesitancy toward COVID-19 vaccination. We found that the overall integration and social integration were associated with the vaccination intention. Some commonly identified barriers (e.g., financial difficulties, language) were not related to COVID-19 vaccination acceptance among migrants in Japan. Highly integrated migrants were less likely to report vaccine hesitancy against COVID-19. To promote COVID-19 acceptance among migrants, customized intervention policies should focus on the migrants with a lower level of integration, especially those with little social connection with the locals.

Abstract Background Widespread use of smartphones has enabled the continuous monitoring of people’s movements and physical activity. Linking global positioning systems (GPS) data obtained via smartphone applications to physical activity data may allow for large-scale and retrospective evaluation of where and how much physical activity has increased or decreased due to environmental, social, or individual changes caused by policy interventions, disasters, and infectious disease outbreaks. However, little attention has been paid to the use of large-scale commercial GPS data for physical activity research due to limitations in data specifications, including limited personal attribute and physical activity information. Using GPS logs with step counts measured by a smartphone application, we developed a simple method for daily walking step estimation based on large-scale GPS data. Methods The samples of this study were users whose GPS logs were obtained in Sendai City, Miyagi Prefecture, Japan, during October 2019 (37,460 users, 36,059,000 logs), and some logs included information on daily step counts (731 users, 450,307 logs). The relationship between land use exposure and daily step counts in the activity space was modeled using the small-scale GPS logs with daily step counts. Furthermore, we visualized the geographic distribution of estimated step counts using a large set of GPS logs with no step count information. Results The estimated model showed positive relationships between visiting high-rise buildings, parks and public spaces, and railway areas and step counts, and negative relationships between low-rise buildings and factory areas and daily step counts. The estimated daily step counts tended to be higher in urban areas than in suburban areas. Decreased step counts were mitigated in areas close to train stations. In addition, a clear temporal drop in step counts was observed in the suburbs during heavy rainfall. Conclusions The relationship between land use exposure and step counts observed in this study was consistent with previous findings, suggesting that the assessment of walking steps based on large-scale GPS logs is feasible. The methodology of this study can contribute to future policy interventions and public health measures by enabling the retrospective and large-scale observation of physical activity by walking.

BACKGROUND: Relative age effect is defined as a phenomenon where children born early generally perform better than children born later in the same cohort. Physical activity is an important factor that might be influenced by the relative age effect. Socioeconomic factors (e.g., parent's income, education level) are also associated with the adolescent's physical activity. However, no existing study has examined whether socioeconomic factors moderate the relative age effect on the adolescent's physical activity. This study aims to clarify whether and how birth month and socioeconomic factors relate to organized sports and physical activity among adolescents in Japan. METHODS: We conducted a questionnaire survey targeting 21,491 adolescents who live in a widespread neighborhood. We included 8102 adolescents (4087 males and 4015 females: mean age 13.1 ± 1.4) in the analysis. Based on the participants' birth months, we divided them into four groups (April to June, July to September, October to December, January to March). We asked participants to report their organized sports participation. Using the International Physical Activity Questionnaire for Japanese Early Adolescents, we identified their moderate to vigorous physical activity (MVPA). Neighborhood-level socioeconomic factors (areal deprivation, average annual income, education level) were analyzed based on national surveys, such as the population census. We performed multilevel logistic and linear regression analysis for organized sports participation and MVPA, respectively. Moreover, a simple slope analysis was implemented if the interaction between birth month and socioeconomic factor was significant in the multilevel linear regression analysis. RESULTS: Among males, relatively younger adolescents (adolescents who were born later in the same grade) were less likely to participate in organized sports activites (OR=0.90, 95% CI 0.82-0.97, p<0.05), while both males and females engaged in less MVPA (b=-0.54, b=-0.25, p< 0.01, respectively). We observed an interaction between birth month and socioeconomic factors. Among males in low-income neighborhoods, and females in more deprived neighborhoods, relatively younger adolescents engaged in less MVPA. CONCLUSIONS: Socioeconomic factors moderate the relative age effect on adolescents' physical activity. The relative age effect on adolescents' physical activity might be more likely to appear among adolescents from socioeconomically disadvantaged neighborhoods.

BACKGROUND: Previous studies have shown that socioeconomic factors are associated with cancer incidence and stage at diagnosis; however, relevant findings in Japan are limited. We examined the association between socioeconomic status and cancer incidence, stage at diagnosis, and detection status by screening, as assessed by the areal deprivation index (ADI), using population-based cancer registry data. METHODS: A total of 79,816 cases including stomach, colorectal, lung, female breast, and cervical cancer diagnosed in Miyagi Prefecture between 2005 and 2010 were analyzed. After calculating the ADI at the place of residence in each case, we examined the association between quintiles of ADI and age-adjusted incidence rates of all stages and advanced stages by sex and site using Poisson regression analysis. The association between the ADI and the proportion of screen-detected cancers was also examined using logistic regression analysis. RESULTS: The age-adjusted incidence rates of all sites and lung cancer in men and lung cancer and cervical cancer in women tended to increase significantly in areas with a higher ADI. The age-adjusted incidence rates of advanced-stage cancers were significantly higher for all sites and lung cancer in both sexes, and stomach and colorectal cancer in men. The proportion of screen-detected cancer tended to be significantly lower in areas with a higher ADI for stomach and colorectal cancer in men. CONCLUSION: Our results indicate that socioeconomic disparities may affect cancer incidence and early diagnosis in Japan. These results suggest the importance of cancer control measures targeting people with low socioeconomic status in Japan.

Evidence suggests that neighbourhood street connectivity is positively associated with physical activity, yet few studies have estimated its associations with sedentary behaviour. We estimated the associations between space syntax derived street integration, a novel measure of street connectivity, and sedentary behaviours among Canadian adults. Data were sourced from a population-based study–Alberta’s Tomorrow Project (n = 14,758). Items from the International Physical Activity Questionnaire captured sedentary behaviour, including sitting and motor vehicle travel time and walking. Street integration was measured within a 1600m radius of participants’ homes. Covariate-adjusted linear regression models estimated the associations between street integration and sedentary behaviour. Street integration was significantly positively associated with daily minutes of sitting on week (b 6.44; 95CI 3.60, 9.29) and weekend (b 4.39; 95CI 1.81, 6.96) days, and for week and weekend days combined (b 5.86; 95CI 3.30, 8.41) and negatively associated with daily minutes of motor vehicle travel (b -3.72; 95CI -3.86, -1.55). These associations remained significant after further adjustment for daily walking participation and duration. More research is needed to understand the pathways by which street integration positively and or negatively affects sedentary behaviour.

OBJECTIVES: Contact tracing for COVID-19 relies heavily on the cooperation of individuals with authorities to provide information of contact persons. However, few studies have clarified willingness to cooperate and motivation to provide information for contact tracing. This study sought to describe willingness to cooperate and motivation to report contact persons for COVID-19 contact tracing among citizens in Japan, and to assess any associated sociodemographic factors. STUDY DESIGN: Cross-sectional study. METHODS: This was an online-based survey using quota sampling. Participants were asked about their willingness to cooperate in reporting contacts for COVID-19 contact tracing if they tested positive. Participants also responded to questions regarding their reasons for cooperating or not cooperating and provided sociodemographic data. Multiple logistic regression analysis was performed to clarify associations between sociodemographic factors and willingness to cooperate. RESULTS: This study included 2844 participants. The proportion of participants who were not willing to cooperate in reporting contacts was 27.6%, with their main reasons being concerns about causing trouble for the other person and being criticised for revealing their names. Willingness to cooperate was lower among men, young adults and those with an educational level less than a university degree. CONCLUSIONS: To improve the effectiveness of contact tracing, educational campaigns, such as reducing the fear and stigma associated with COVID-19, may be important. Furthermore, it is essential to understand that individuals may have contacts whom they do not wish to disclose to others and to be considerate when handling such situations.

To reduce vaccine hesitancy, it is important to identify factors that can intervene at the individual or community level. Social capital is a possible factor because it is associated with various vaccine hesitancy, such as for measles and influenza. However, limited studies have explored the association between social capital and vaccination for COVID-19, which is an unprecedented pandemic and infodemic. Therefore, this study aimed to clarify the association between social capital and COVID-19 vaccination during the pandemic. This cross-sectional study used quota sampling for an online-based survey. Participants were asked whether they had previously been vaccinated for COVID-19 and their intention to receive a COVID-19 vaccine booster. Social capital was evaluated using three measures (individual-level civic participation, social cohesion, and reciprocity). Multiple logistic regression analysis was performed to clarify the association between social capital and previous COVID-19 vaccination status as well as intention to receive a COVID-19 booster. Participants were 2,313 individuals, of whom 87.2% had received a COVID-19 vaccine; 72.3% intended to obtain a COVID-19 booster. Individuals with any social capital are more likely to receive a COVID-19 vaccination than those with none (OR: 1.73, 95%CI: 1.18-2.54; OR: 1.58, 95%CI: 1.22-2.05; OR: 3.05, 95%CI: 2.15-4.33). These indicators were also associated with the intention to receive a COVID-19 booster. Thus, our results suggest that among the general public, those with individual-level social capital are more likely to receive a COVID-19 vaccination than those with none. Social capital may be a factor that can reduce vaccine hesitancy during a pandemic.

BACKGROUND: Facing a global epidemic of new infectious diseases such as COVID-19, non-pharmaceutical interventions (NPIs), which reduce transmission rates without medical actions, are being implemented around the world to mitigate spreads. One of the problems in assessing the effects of NPIs is that different NPIs have been implemented at different times based on the situation of each country; therefore, few assumptions can be shared about how the introduction of policies affects the patient population. Mathematical models can contribute to further understanding these phenomena by obtaining analytical solutions as well as numerical simulations. METHODS AND RESULTS: In this study, an NPI was introduced into the SIR model for a conceptual study of infectious diseases under the condition that the transmission rate was reduced to a fixed value only once within a finite time duration, and its effect was analyzed numerically and theoretically. It was analytically shown that the maximum fraction of infected individuals and the final size could be larger if the intervention starts too early. The analytical results also suggested that more individuals may be infected at the peak of the second wave with a stronger intervention. CONCLUSIONS: This study provides quantitative relationship between the strength of a one-shot intervention and the reduction in the number of patients with no approximation. This suggests the importance of the strength and time of NPIs, although detailed studies are necessary for the implementation of NPIs in complicated real-world environments as the model used in this study is based on various simplifications.

OBJECTIVES: Some epidemiological studies of older American adults have reported a relationship between life-space mobility (LSM) and mortality. However, these studies did not show a dose-response relationship and did not include individuals from other countries. Therefore, we evaluated the dose-response relationship between LSM and mortality in older adults. DESIGN: Prospective cohort study. SETTING AND PARTICIPANTS: We used the data of 10,014 older Japanese adults (aged ≥65 years) who provided valid responses to the Life-Space Assessment (LSA) in the Kyoto-Kameoka study in Japan. METHODS: LSM was evaluated using the self-administered LSA consisting of 5 items regarding life-space from person's bedroom to outside town. The LSM score was calculated by multiplying life-space level by frequency score by independence score, yielding a possible range of 0 (constricted life-space) to 120 (broad life-space). These scores were categorized into quartiles (Qs). Mortality data were collected from July 30, 2011 to November 30, 2016. A multivariate Cox proportional hazards model that included baseline covariates were used to evaluate the relationship between LSM score and mortality risk. RESULTS: A total of 1030 deaths were recorded during the median follow-up period of 5.3 years. We found a negative association between LSM score and overall mortality even after adjusting for confounders [Q1: reference; Q2: hazard ratio (HR) 0.81, 95% CI 0.69-0.95; Q3: HR 0.70, 95% CI 0.59-0.85; Q4: HR 0.68, 95% CI 0.55-0.84, P for trend < .001]. Similar results were observed for the spline model; up to a score of 60 points, LSM showed a strong dose-dependent negative association with mortality, but no significant differences were observed thereafter (L-shaped relationship). CONCLUSIONS AND IMPLICATIONS: Our findings demonstrate an L-shaped relationship between LSM and mortality. This study will be useful in establishing target values for expanding the range of mobility among withdrawn older adults with a constricted life-space.

Large migrations from major cities were observed in many countries in 2020 when the COVID-19 pandemic spread worldwide. In Japan, the number of out-migrants from the Tokyo metropolis has increased and the pattern of internal migration has changed due to the pandemic. This article examines changes in destinations of migrants from Tokyo special wards, the central part of the Tokyo metropolitan area. As a result, the suburban areas of the Tokyo metropolitan area and northwest and southwest regions outside it were identified as regional destination clusters that received increased numbers of migrants from Tokyo special wards. The characteristics of the regions and age and occupational compositions of in-migrants indicated that the pandemic facilitated so-called lifestyle migration from the metropolitan center in Japan.

In the context of rapid urbanization, public open spaces in dense urban areas are critical built environment elements to support active lifestyles. Several reviews have explored the associations of public open space attributes with physically active and sedentary behavior. However, few reviews have included studies from Asia, and no studies have focused on dense urban areas. This systematic review analyzed 18 observational studies investigating associations between public open space attributes with physical activity and sedentary behavior in dense urban areas of East Asian countries, including Japan, Taiwan, China, and Hong Kong. We found that closer distance to and a greater number of public open spaces and features within them were positively associated with leisure-time physical activity. Places near water features and corridors within public open spaces were associated with more sedentary behavior. These findings inform landscape and urban design guidelines for (re)designing public open spaces to support active lifestyles in high dense urban areas.

BACKGROUND: Many epidemiological studies have reported the association between exposure to particulate matter and mortality, but long-term prospective studies from Asian populations are sparse. Furthermore, associations at low levels of air pollution are not well clarified. Here, we evaluated associations between long-term exposure to particulate matter <2.5 µg/m3 (PM2.5) and mortality in a Japanese cohort with a relatively low exposure level. METHODS: The Japan Public Health Center-based Prospective Study (JPHC Study) is a prospective cohort study of men and women aged 40-69 years in 1990 who were followed up through 2013 for mortality. In this cohort of 87,385 subjects who did not move residence during follow-up, average PM2.5 levels from 1998 to 2013 by linkage with 1-km2 grids of PM2.5 concentration were assigned to the residential addresses of all participants. To avoid exposure misclassification, we additionally evaluated the association between 5-year (1998-2002) cumulative exposure level and mortality during the follow-up period from 2003 to 2013 in 79,078 subjects. Cox proportional hazards models were used to calculate the association of long-term exposure to PM2.5 on mortality, with adjustment for several individual confounding factors. RESULTS: Average PM2.5 was 11.6 µg/m3. Average PM2.5 exposure was not associated with all-cause mortality or cancer and respiratory disease mortality. However, average PM2.5 was positively associated with mortality from cardiovascular disease (hazard ratio (HR) of 1.23 (95%CI=1.08-1.40) per 1-µg/m3 increase; in particular, HR in mortality from cerebrovascular disease was 1.34 (95%CI=1.11-1.61) per 1-µg/m3 increase. Additionally, these results using cumulative 5-year PM2.5 data were similar to those using average PM2.5 over 15 years. CONCLUSIONS: We found evidence for a positive association between PM2.5 exposure and mortality from cardiovascular disease in a Japanese population, even in an area with relatively low-level air pollution.

Workplace settings-both internal and external-can influence how workers are physically active or sedentary. Although research has identified some indoor environmental attributes associated with sitting at work, few studies have examined associations of workplace neighbourhood built-environment attributes with workplace sitting time. We examined the cross-sectional associations of perceived and objective workplace neighbourhood built-environment attributes with sitting time at work and for transport among desk-based workers in Japan. Data were collected from a nationwide online survey. The Abbreviated Neighborhood Environment Walkability Scale (n = 2137) and Walk Score® (for a subsample of participants; n = 1163) were used to assess perceived and objective built-environment attributes of workplace neighbourhoods. Self-reported daily average sitting time at work, in cars and in public transport was measured using a Japanese validated questionnaire. Linear regression models estimated the associations of workplace neighbourhood built-environment attributes with sitting time. All perceived workplace neighbourhood built-environment attributes were positively correlated with Walk Score®. However, statistically significant associations with Walk Score® were found for sitting for transport but not for sitting at work. Workers who perceived their workplace neighbourhoods to be more walkable reported a longer time sitting at work and in public transport but a shorter sitting time in cars. Our findings suggest that walkable workplace neighbourhoods may discourage longer car use but have workplaces where workers spend a long time sitting at work. The latter finding further suggests that there may be missed opportunities for desk-based workers to reduce sitting time. Future workplace interventions to reduce sitting time may be developed, taking advantage of the opportunities to take time away from work in workplace neighbourhoods.

There has been growing interest in the role of pet ownership, particularly dog ownership, in managing noncommunicable diseases. The built environment can act as a facilitator or barrier to owning a dog or dog walking. Nevertheless, limited studies conducted in different geographical contexts have examined how the built environment can influence dog ownership and dog walking. In this interdisciplinary article, using Japan as a case study, we identify key design challenges to owning and walking dogs in dense urban areas as a means of promoting health and wellbeing.

Background: Among high-income countries, Japan has a low prevalence of obesity, but little is understood about subnational trends and variations in body mass index (BMI), largely owing to the lack of data from representative samples of prefectures. We aimed to examine long-term trends and distributions of adult BMI at the prefecture level in Japan from the late 1970s using a spatiotemporal model. Methods: We obtained cross-sectional data for 233,988 men and 261,086 women aged 20-79 years from the 44 annual National Health and Nutrition Surveys (NHNS) conducted during 1975-2018. We applied a Bayesian spatiotemporal model to estimate the annual time series of age-standardized and age-specific mean BMI by 20-year age group and sex for each of the 47 prefectures. We assessed socioeconomic inequalities in BMI across prefectures using the concentration index, according to population density. Results: In men, the age-standardized prefectural mean BMI ranged from 21.7 kg/m2 (95% credible interval, 21.6-21.9) to 23.1 kg/m2 (22.9-23.4) in 1975 and from 23.5 kg/m2 (23.3-23.7) to 24.8 kg/m2 (24.6-25.1) in 2018. In women, the age-standardized prefectural mean BMI ranged from 22.0 kg/m2 (21.9-22.2) to 23.4 kg/m2 (23.2-23.6) in 1975 and from 21.7 kg/m2 (21.6-22.0) to 23.5 kg/m2 (23.2-23.8) in 2018. Mean BMI was highest in the southernmost prefecture for most of the study period, followed by northeast prefectures. The increase in mean BMI was largest in southwest prefectures, which caught up with northeast prefectures over time. The concentration index was negative, indicating higher BMI in less-populated prefectures. Absolute values of the concentration index were greater in women than in men and increased over time. Conclusions: There were variations in adult mean BMI across prefectures, and geographic distributions changed over time. Further national and local efforts are needed to address the rising trend in mean BMI, particularly among men in rural prefectures, and socioeconomic inequalities among women. Bayesian hierarchical modeling is useful for reconstructing long-term spatiotemporal trends of mean BMI by integrating small-sized survey samples at the prefecture level in the NHNS.

Studies from many countries, including Japan, have reported decreased physical activity during the coronavirus disease 2019 (COVID-19) pandemic. However, the individual attributes as related to changes in physical activity during the pandemic in Japan have been scarcely investigated. The present study explored the relationships among individual attributes including demographic, socioeconomic, and geographic characteristics, work situation changes, perception of anxiety, and changes in walking and sedentary behaviors, during the pandemic in Japan. To obtain data indicating individual circumstances during the first wave of the pandemic in Japan, we conducted a nationwide online survey from May 19 to May 23, 2020 (n = 1,200). To observe changes in walking behavior objectively and retrospectively, we collected data on the number of daily steps as measured by the iPhone's Health application. Path analysis was employed to examine relationships between individual attributes and changes in walking and sedentary behaviors. Decreased physical activity, especially, decreased walking behavior among younger individuals and those living in highest-density neighborhoods were identified. There was increased sedentary behavior among females. Moreover, individuals with higher socioeconomic status (SES) tended to become inactive due to work-from-home/standby-at-home and individuals with lower SES tended to become inactive due to decreased amount of work. Decreased walking behavior and increased sedentary behavior were associated with a perception of strong anxiety related to the pandemic. Our findings would be helpful in considering measures to counteract health risks during the pandemic by taking into account individual backgrounds.

Objectives: We aimed to identify the concerns, current implementation status and correct usage, and factors inhibiting implementation and correct use of a COVID-19 contact tracing application among the ordinary citizens in Japan. Study design: This was a cross-sectional study based on an internet survey completed by 2013 participants who were selected among registrants of an Internet research company between September 8 and 13, 2020. Methods: Participants completed an online survey that included thoughts and concerns about the application, status of use, and questions about whether the application was being used correctly. We performed multiple logistic regression analysis to clarify the association between the use of the app and sociodemographic factors and user concerns. Results: Of the 2013 respondents, 429 (21.3%) participants reported using this application, but only 60.8% of them used it correctly. The percentage of those having some concerns about the application ranged from 45.9% to 75.5%, with the highest percentage being 'doubts about effectiveness of apps for preventing spread of infection'. Multiple logistic regression analysis revealed, the main concerns inhibiting application use were insufficient knowledge of how to use it, privacy concerns, doubts about the effectiveness of the app, and concerns about battery consumption and communication costs. Additionally, the prevalence of the application was lower for lower-income individuals. Conclusions: The findings suggest that income may create inequalities in the efficacy and effectiveness of COVID-19 contact tracing applications. Awareness activity strategies to dispel such concerns and support low-income individuals may be needed.

Vaccine hesitancy regarding the coronavirus disease 2019 (COVID-19) vaccine is widespread during the COVID-19 pandemic. Many recent studies have reported that the confidence of the vaccination and perceived risk were associated with vaccination intent, yet few studies have focused on other psychological factors. This study aimed to clarify the trends in COVID-19 vaccination intent and to identify the association between the 5C psychological antecedents and COVID-19 vaccination intent by sex and age in Japan. This was a longitudinal study conducted through an Internet-based survey from January 2021 to April 2021 before and after vaccine distribution in Japan, including 2,655 participants recruited by quota sampling. Participants were asked to indicate how likely they were to get vaccinated against COVID-19. In the second survey, the participants responded to questions regarding the 5C psychological antecedents: confidence, complacency, constraints (structural and psychological barriers), calculation (engagement in extensive information searching), and collective responsibility (willingness to protect others). Multiple logistic regression analysis was performed to clarify the association between the 5C psychological antecedents and COVID-19 vaccination intent in the second wave survey. COVID-19 vaccination intent improved from 62.1% to 72.4% after vaccine distribution, but no significant difference was found in young men. Confidence and collective responsibility were positively associated with vaccination intent, and calculation was negatively associated among all generations. COVID-19 vaccination intent may be affected not only by confidence and constraints but also by calculation and collective responsibility, and further research is needed.

Walk Score® is a free web-based tool that provides a walkability score for any given location. A limited number of North American studies have found associations between Walk Score® and perceived built environment attributes, yet it remains unknown whether similar associations exist in Asian countries. The study's objective is to examine the covariate-adjusted correlations between the Walk Score® metric and measures of the perceived built environment in ultrahigh density areas of Japan. Cross-sectional data were obtained from a randomly selected sample of adult residents living in two Japanese urban localities. There was a large correlation between Walk Score® and access to shops (0.58; p < 0.001). There were medium correlations between Walk Score® and population density (0.38; p < 0.001), access to public transport (0.34; p < 0.001), presence of sidewalks (0.41; p < 0.001), and access to recreational facilities (0.37; p < 0.001), and there was a small correlation between Walk Score® and presence of bike lanes (0.16; p < 0.001). There was a small negative correlation between Walk Score® and traffic safety (-0.13; p < 0.001). There was a medium correlation between Walk Score® and overall perceived walkability (0.48; p < 0.001). This study's findings highlight that Walk Score® was correlated with several perceived walkable environment attributes in the context of ultrahigh density areas in Asia.

Despite the increasing knowledge on the association between neighborhood and health, few studies have investigated sleep disorders in Japan, particularly the impact of neighborhood noise on sleep. Thus, this study aimed to investigate the associations between insomnia symptoms and annoyance because of traffic and neighborhood noise in Japan, which has different neighborhood conditions compared with those of the western societies. Neighborhood built and socioeconomic environments roles were also examined. We used nationwide cross-sectional data collected through a 2015 online survey of Japanese adults aged 20-64 years (n = 4,243). Adjusted prevalence ratios for insomnia according to the exposures were estimated using the multilevel Poisson regression models. The results showed that having insomnia was significantly associated with experiencing neighborhood and traffic-noise annoyance. Neighborhood noise had a stronger and independent association with insomnia. However, the neighborhood environmental variables, including population density, deprivation index, and access to commercial areas, were not associated with insomnia. In conclusion, noise annoyance, particularly that sourced from neighbors, is an important factor in relation to sleep health. Health and urban-planning policymakers should consider neighborhood noise, in addition to traffic noise, as health-related issues in residential neighborhoods.

No previous study has ever explored the association between coastal exposure and the mental health of residents in a post-disaster context. Therefore, we aimed to confirm whether there was an association between sea visibility and coastal proximity and the mental health of coastal residents a devastating tsunami. We targeted 15 coastal municipalities located in the Miyagi Prefecture, and obtained data from a community-based cohort study. The baseline survey was initiated 2 years after the 2011 Great East Japan Earthquake and Tsunami and the secondary survey was initiated 6 years after the disaster. We applied multilevel mixed-effects models to the longitudinal data. Our outcome measure was the Kessler Psychological Distress Scale (K6) score. We assessed the data collected from 2,327 respondents on both surveys as of April 2018 for this ongoing cohort study. We found that neither sea visibility nor coastal proximity was significantly associated with the recovery of mental health after the disaster. However, we found a distinctive trend of mental health recovery in people who lived alone with a sea view, indicating that visibility of the sea had a negative effect on their mental health immediately after the GEJET, but that the negative effect was subsequently eliminated.

OBJECTIVES: To examine the associations between domain-specific sedentary and active behaviours and workers' presenteeism and absenteeism in a sample of company employees. METHODS: This study recruited participants (n = 2,466) from a nationwide online survey database (Japan,2019). Participants completed a questionnaire that captured data on relative and absolute presenteeism and absenteeism and domain-specific physical activity, and sedentary behaviours. RESULTS: Daily minutes of work-related physical activity was negatively associated with relative absenteeism. Daily minutes of leisure-related physical activity was positively associated with absolute presenteeism (i.e., better productivity). Daily minutes of total physical activity were negatively and positively associated with relative absenteeism and absolute presenteeism (i.e., better productivity). There was also a positive association between car sitting time and absolute absenteeism. CONCLUSIONS: A change in work culture and practices that support active behaviours at work and outside of work may improve employee's productivity indices.

BACKGROUND: As the COVID-19 pandemic spread, the Japanese government declared a state of emergency on April 7, 2020 for seven prefectures, and on April 16, 2020 for all prefectures. The Japanese Prime Minister and governors requested people to adopt self-restraint behaviors, including working from home and refraining from visiting nightlife spots. However, the effectiveness of the mobility change due to such requests in reducing the spread of COVID-19 has been little investigated. The present study examined the association of the mobility change in working, nightlife, and residential places and the COVID-19 outbreaks in Tokyo, Osaka, and Nagoya metropolitan areas in Japan. METHODS: First, we calculated the daily mobility change in working, nightlife, and residential places compared to the mobility before the outbreak using mobile device data. Second, we estimated the sensitivity of mobility changes to the reproduction number by generalized least squares. RESULTS: Mobility change had already started in March, 2020. However, mobility reduction in nightlife places was particularly significant due to the state of emergency declaration. Although the mobility in each place type was associated with the COVID-19 outbreak, the mobility changes in nightlife places were more significantly associated with the outbreak than those in the other place types. There were regional differences in intensity of sensitivity among each metropolitan area. CONCLUSIONS: Our findings indicated the effectiveness of the mobility changes, particularly in nightlife places, in reducing the outbreak of COVID-19.

BACKGROUND: Recent studies indicate an urgent need to take action against mental health issues during the COVID-19 pandemic. However, the association between larger-scale environmental factors such as living conditions and mental health problems during the pandemic is currently unknown. METHODS: A nationwide, cross-sectional internet survey was conducted in Japan between August and September 2020 to examine the association between urbanization level and neighborhood deprivation as living conditions and COVID-19 case numbers by prefecture. Prevalence ratios (PRs) for severe psychological distress, suicidal ideation, and new-onset suicidal ideation during the pandemic were adjusted for potential confounders. RESULTS: Among 24,819 responses analyzed, the prevalence of mental health problems was 9.2% for severe psychological distress and 3.6% for new-onset suicidal ideation. PRs for severe psychological distress were significantly associated with higher urbanization level (highest PR = 1.30, 95% CI = 1.08-1.56). PRs for new-onset suicidal ideation were significantly associated with higher urbanization level (highest PR = 1.83, 95% CI = 1.37-2.45) and greater neighborhood deprivation (highest PR = 1.35, 95% CI = 1.06-1.72). Severe psychological distress and new-onset suicidal ideation were significantly more prevalent when there was higher urbanization plus lower neighborhood deprivation (PR = 1.34 [1.15-1.56], and 1.57 [1.22-2.03], respectively). CONCLUSION: These findings suggest that it is not the number of COVID-19 cases by residence area but higher urbanization level and greater neighborhood deprivation (lower neighborhood-level socioeconomic status) that are associated with severe psychological distress and new-onset suicidal ideation during the pandemic. These findings differ in part from evidence obtained before the pandemic.

BACKGROUND: Sedentary behaviors and physical activity are likely to be affected by the COVID-19 outbreak, and sedentary lifestyles can increase subjective fatigue. The nonpharmaceutical policies imposed as a result of the COVID-19 pandemic may also have adverse effects on fatigue. OBJECTIVE: This study has two aims: to examine the changes in sedentary behaviors and physical activity of company workers in response to the COVID-19 pandemic in Japan and to examine relationships between changes in these sedentary behaviors and physical activity and changes in fatigue. METHODS: Data from a nationwide prospective online survey conducted in 2019 and 2020 were used. On February 22, 2019, an email with a link to participate in the study was sent to 45,659 workers, aged 20 to 59 years, who were randomly selected from a database of approximately 1 million individuals. A total of 2466 and 1318 participants, who self-reported their occupation as company workers, answered the baseline and follow-up surveys, respectively. Surveys captured fatigue, workday and daily domain-specific sedentary behaviors and physical activity, and total sedentary behaviors and physical activity. We used multivariable linear regression models to estimate associations of changes in sedentary behaviors and physical activity with changes in fatigue. RESULTS: Increases in public transportation sitting during workdays, other leisure sitting time during workdays, and other leisure sitting time were associated with an increase in the motivation aspect of fatigue (b=0.29, 95% CI 0-0.57, P=.048; b=0.40, 95% CI 0.18-0.62, P<.001; and b=0.26, 95% CI 0.07-0.45, P=.007, respectively). Increases in work-related sitting time during workdays, total sitting time during workdays, and total work-related sitting time were significantly associated with an increase in the physical activity aspect of fatigue (b=0.06, 95% CI 0-0.12, P=.03; b=0.05, 95% CI 0.01-0.09, P=.02; and b=0.07, 95% CI 0-0.14, P=.04, respectively). The motivation and physical activity aspects of fatigue increased by 0.06 for each 1-hour increase in total sitting time between baseline and follow-up (b=0.06, 95% CI 0-0.11, P=.045; and b=0.06, 95% CI 0.01-0.10, P=.009, respectively). CONCLUSIONS: Our findings demonstrated that sedentary and active behaviors among company workers in Japan were negatively affected during the COVID-19 outbreak. Increases in several domain-specific sedentary behaviors also contributed to unfavorable changes in workers' fatigue. Social distancing and teleworking amid a pandemic may contribute to the sedentary lifestyle of company workers. Public health interventions are needed to mitigate the negative effects of the COVID-19 pandemic or future pandemics on sedentary and physical activity behaviors and fatigue among company workers.

Studies have reported that many people changed their going-out behavior in response to the declaration of a state of emergency related to the coronavirus disease 2019 (COVID-19) in Japan. However, individual attributes of those who tended to stay home have not been examined. Therefore, this study examined the demographic, socioeconomic, and geographic characteristics of people who refrained from going out both before and after a state of emergency was declared. Using data from a nationwide online survey, this study retrospectively investigated the relative amount of time spent outside the home between mid-February and mid-May 2020. Multilevel linear regression analysis was performed to examine the association of time outside with demographic, socioeconomic, and geographic characteristics, and with the anxiety related to going out, in each period. Overall, respondents significantly reduced their time spent outside during the study period, especially after a state of emergency was declared. Those who were young, female, living with two or more people, had lower income, were not working, used public transportation, had chronic disease, and lived in large metropolitan areas were more likely to reduce time outside during a part of the study period. However, no significant differences were observed for occupational class, education, and neighborhood population density. Thus, the results showed a reduction in time outside during the COVID-19 outbreak and the existence of demographic, socioeconomic, and geographic differences in going-out behavior. Socioeconomic disparities and neighborhood differences in going-out behavior, and their influence on health should be continuously monitored.

OBJECTIVES: Neighbourhood characteristics can impact the health of residents. This study investigated associations between objectively derived neighbourhood characteristics, including novel space syntax metrics, and self-reported body mass index (BMI) among Canadian men and women. METHODS: Our study included survey data collected from a random cross-section of adults residing in Calgary, Alberta (n = 1718). The survey, conducted in 2007/2008, captured participants' socio-demographic characteristics, health, and weight status (BMI). Participants' household postal codes were geocoded and 1600-m line-based network buffers estimated. Using a geographical information system, we estimated neighbourhood characteristics within each buffer including business destination density, street intersection density, sidewalk length, and population density. Using space syntax, we estimated street integration and walkability (street integration plus population density) within each buffer. Using adjusted regression models, we estimated associations between neighbourhood characteristics and BMI (continuous) and BMI categories (healthy weight vs. overweight including obese). Gender-stratified analysis was also performed. RESULTS: Business destination density was negatively associated with BMI and the odds of being overweight. Among men, street intersection density and sidewalk length were negatively associated with BMI and street intersection density, business destination density, street integration, and space syntax walkability were negatively associated with odds of being overweight. Among women, business destination density was negatively associated with BMI. CONCLUSION: Urban planning policies that impact neighbourhood design have the potential to influence weight among adults living in urban Canadian settings. Some characteristics may have a differential association with weight among men and women and should be considered in urban planning and in neighbourhood-focussed public health interventions.

We aimed to clarify the status of hand hygiene practices among ordinary citizens during the COVID-19 pandemic in Japan, in conjunction with the total frequency of daily hand hygiene as an indicator of education and evaluation. This cross-sectional study was based on an Internet survey completed by 2,149 participants (age range: 20-79 years, 51.0% men, response rate: 89.5%), selected during June 23-28, 2020. The participants responded regarding the frequency of implementing hand hygiene at 5 moments (after returning from a public place; after using the toilet; after touching something outside; before eating food; and after blowing your nose, coughing, or sneezing). Additionally, participants responded regarding the number of daily hand hygiene events. The cutoff value of the total number of daily hand hygiene events to determine whether hand hygiene was performed in all 5 moments was clarified using ROC analysis. The mean number of hand hygiene events was 10.2 times/day. The prevalence of implementing hand hygiene at each moment ranged from 30.2% to 76.4%; only 21.1% practiced in all moments. Both Youden Index and specificity were high when the cut-off value was 11 times/day. The criterion of hand hygiene: ≥11 times/day may be useful in education and evaluation.

Understanding spatial interactions such as human mobility has been one of the main analytical themes in geography, spatial economics, and traffic engineering for a long time. The intervening opportunities models, including the radiation model, provide a framework to elucidate spatial interactions generated by an individual's distance-ordered decision-making process. However, such classical definitions of intervening opportunities have often failed to predict realistic flow volumes, particularly for short-distance flows. To overcome this problem, we have proposed a new formulation of intervening opportunities with a kernel function to introduce a fuzziness in spatial search behaviours of destinations, to develop a new variant of the radiation model. The mobility patterns resulting from the modified radiation model that included kernel-based intervening opportunities outperformed the original radiation model when fitted to four datasets of inter-regional flows.

Recently, overseas studies have focused on the interaction effects between accessibility to open spaces and individual-level poverty (e.g., income) as a factor of social inequalities in health. These studies have reported that people with a higher degree of individual-level poverty are more likely to be vulnerable to negative health effects due to inferior accessibility to open spaces, which may contribute to social inequalities in health. However, few studies have focused on the interaction effect between accessibility to open spaces and area-level poverty. We hypothesized that individuals living in areas with a high degree of area-level poverty are more likely to experience negative health effects due to inferior perceived accessibility to open spaces. We conducted the following study using data obtained through a mailed questionnaire survey in the Densely Inhabited District of Osaka Prefecture, Japan. Initially, we tested for health disparities related to subjective health, subjective well-being, and frequency of exercise. Next, we examined which of the above-mentioned interaction effects had a more significant impact on health. Our results showed health disparities in subjective health and subjective well-being. The interaction effect between perceived accessibility and area-level poverty had a more significant health impact than the other interaction effects on subjective health. None of the two interaction effects had any significant effects on subjective well-being and frequency of exercise. Policy implications for reducing social inequalities in health may include measures to improve the perceived accessibility to open spaces of residents in areas with a high degree of area-level poverty.

The purpose of this study was to visualize how regional differences observed from the population census deviate from their "true" forms due to an increase in unreported (missing) cases by considering multiple scenarios in which there was an increase in the number of unreported cases in the census. For municipalities in the Tokyo metropolitan area, we estimated the percentages of unmarried people and those with short-term residence from the 2015 Population Census for different scenarios of unreported rates using 1) proportional distribution by age-group and 2) weighted distribution based on the ratio of unreported rates among attributes. In both indicators, the results showed that there were clear regional differences with high and low percentages in urban centers and suburban areas, respectively, in a scenario where the unreported rate became zero. However, when we examined the maps estimated under scenarios where the unreported rates increased by 1.5- or 2-fold, such regional differences appeared to be reduced or eliminated. This means that further increases in the number of unreported cases will increase the probability of spurious regional differences in the future. Careful interpretation of the results and use of statistically corrected data are required when analyzing the census data for items and regions with high unreported rates.

Objective: Apple Inc's iPhone Health App automatically records daily steps of the iPhone users. We developed a method to obtain the recorded step counts from the screenshot images of Health App. We examined the practicality of the method through an Internet survey by which we intended to detect regional and demographic variations in the degree of step count drop under the declaration of a state of emergency against spreading of COVID-19. Methods: A total of 1,200 daily iPhone users aged 20-69 years living in Japan among registered monitors of an Internet survey company were surveyed, resulting in screenshot images of iPhone Health App. We developed a program to read the daily numbers of steps from the screenshot images, and confirmed the changes in the average number of steps from February 19 to May 19, 2020. Results: About 79.9% of the collected images were able to be used for the machine reading of daily step counts without errors. The causes of errors were examined for the improvement of the proposed methods. Using a fixed effects model, it was estimated that the average number of daily steps significantly decreased after the declaration of the state of emergency, and the observed tendency was consistent with previous studies in Tokyo. We also identified significant regional and age variations of step-count decrease. Largest drops of daily step count were observed for the group of aged 20-29 year-old living in three major metropolitan areas: average decrease of daily steps of men and women in the group were 2,712 and 2,663, respectively. Conclusion: This study indicated that the newly developed method to automatically read the number of steps from screenshot images of iPhone collected through an Internet survey is an effective way to objectively and retrospectively measure temporal changes of step counts of people.

BACKGROUND: Few studies have examined the associations between urban design attributes and older adults' physical function. Especially, it is not well known how built-environment attributes may influence physical function in Asian cities. The aim of this study was to examine associations between objectively measured environmental attributes of walkability and objectively assessed physical function in a sample of Japanese older adults. METHODS: Cross-sectional data collected in 2013 from 314 older residents (aged 65-84 years) living in Japan were used. Physical function was estimated from objectively measured upper- and lower-body function, mobility, and balance by a trained research team member. A comprehensive list of built-environment attributes, including population density, availability of destinations, intersection density, and distance to the nearest public transport station, were objectively calculated. Walk Score as a composite measure of neighborhood walkability was also obtained. RESULTS: Among men, higher population density, availability of destinations, and intersection density were significantly associated with better physical function performance (1-legged stance with eyes open). Higher Walk Score was also marginally associated with better physical function performance (1-legged stance with eyes open). None of the environmental attributes were associated with physical function in elderly women. CONCLUSION: Our findings indicate that environmental attributes of walkability are associated with the physical function of elderly men in the context of Asia. Walking-friendly neighborhoods can not only promote older adults' active behaviors but can also support their physical function.

BACKGROUND: Many desk-based workers can spend more than half of their working hours sitting, with low levels of physical activity. Workplace neighbourhood built environment may influence workers' physical activities and sedentary behaviours on workdays. We reviewed and synthesised evidence from observational studies on associations of workplace neighbourhood attributes with domain-specific physical activity and sedentary behaviour and suggested research priorities for improving the quality of future relevant studies. METHODS: Published studies were obtained from nine databases (PubMed, Web of Science, PsycINFO, Scopus, Transport Research International Documentation, MEDLINE, Cochrane, Embase, and CINAHL) and crosschecked by Google Scholar. Observational studies with quantitative analyses estimating associations between workplace neighbourhood built environment attributes and workers' physical activity or sedentary behaviour were included. Studies were restricted to those published in English language peer-reviewed journals from 2000 to 2019. RESULTS: A total of 55 studies and 455 instances of estimated associations were included. Most instances of potential associations of workplace neighbourhood built environment attributes with total or domain-specific (occupational, transport, and recreational) physical activity were non-significant. However, destination-related attributes (i.e., longer distances from workplace to home and access to car parking) were positively associated with transport-related sedentary behaviour (i.e., car driving). CONCLUSIONS: The findings reinforce the case for urban design policies on designing mixed-use neighbourhoods where there are opportunities to live closer to workplaces and have access to a higher density of shops, services, and recreational facilities. Studies strengthening correspondence between the neighbourhood built environment attributes and behaviours are needed to identify and clarify potential relationships. PROTOCOL REGISTRATION: The protocol of this systematic review was registered on the International Prospective Register of Systematic Reviews (PROSPERO) on 2 December 2019 (registration number: CRD42019137341 ).

Although the pedestrian-friendly qualities of streetscapes promote walking, quantitative understanding of streetscape functionality remains insufficient. This study proposed a novel automated method to assess streetscape walkability (SW) using semantic segmentation and statistical modeling on Google Street View images. Using compositions of segmented streetscape elements, such as buildings and street trees, a regression-style model was built to predict SW, scored using a human-based auditing method. Older female active leisure walkers living in Bunkyo Ward, Tokyo, are associated with SW scores estimated by the model (OR = 3.783; 95% CI = 1.459 to 10.409), but male walkers are not.

Few studies examine associations between objectively-calculated neighbourhood built environment attributes and objectively-assessed sedentary behaviour in different geographical locations, especially in highly-populated environments. Additionally, no study, to our knowledge, has investigated associations between objective measures of neighbourhood built environment attributes and objectively-assessed sedentary behaviours in middle-aged adults, despite the fact that this is a critical stage of life when age-related functional decline begins. We examined the associations between neighbourhood built environment attributes with the total, and patterns of, objectively-assessed sedentary behaviours in a densely-populated area in Asia. Data from 866 adults (ages 40 to 64) living in Japan were included. Four classifications of sedentary behaviours, including daily total sedentary time, duration and number of long (≥30 min) sedentary bouts and breaks per sedentary hour, were estimated using hip-worn accelerometers. Individual (population density, availability of destinations, number of intersections, and distance to the nearest park) and composite (walkability and Walk Score®) neighbourhood built environment indices were calculated using geographic information systems. Covariate-adjusted multilevel linear mixed effects models were used to estimate the associations between the neighbourhood built environment attributes and sedentary behaviours. Population density and availability of destinations were positively associated with sedentary behaviours; however, the number of intersections was negatively associated with sedentary behaviours. No associations were observed between the distance to the nearest park and sedentary behaviours. There were positive associations between walkability and total sedentary time, and duration and the number of long sedentary bouts. Walk Score® was positively associated with total sedentary time and the number of long sedentary bouts. These findings suggest that urban design attributes supportive of walking (except for the number of intersections) may encourage sedentary behaviour among middle-aged adults living in densely-populated environments.

Although the health risks and benefits of coastal areas have long been researched, these effects of the different types of coastlines have rarely been explored on the evacuees living near the coast, in a post-disaster context. Thus, this study aimed to explore, with the passing of years after a disaster, what kind of coastline is a useful public health resource as a post-disaster reconstruction approach in coastal environments that have suffered significantly from the tsunami disaster in northeast Japan in 2011. This study compared the evacuees' mental health based on proximity to the coast and the types of coastlines (artificial, semi-natural, and natural). Data were drawn from the Miyagi Prefectural Government surveys, which targeted almost all evacuees of the 2011 Great East Japan Earthquakes and Tsunami (n = 96,203). We applied a pooled Poisson regression model to a repeated cross-sectional dataset of evacuees' mental health between 2012 and 2016. Moderate psychological distress, measured via the Kessler Psychological Distress Scale (K6) score, was the dependent variable, while proximity to the coast and type of coastline were the independent variables. The estimated main effects of type of coastline indicated that overall associations between K6 ≥5 and all types of coastlines within a 1.6 km buffer of participants' residential space were not statistically significant (p > 0.05). However, among types of coastlines, the interaction terms of semi-natural coastline × year (2015 and 2016) were significantly associated with lower incidence rate ratios (IRR), which decreased in 2015 and 2016 (IRR: 0.88, 95%CI: 0.79-0.98; IRR: 0.78, 95%CI: 0.68-0.90, respectively). Further, we computed the marginal effects of coastline types for each year to observe differences in the impact on moderate psychological distress depending on different accessible coastline types within a distance of 1.6 km from the participants' living space. We found that, after the revision of the coastal act in 2014, the moderate mental stress of participants who lived around semi-natural coastlines significantly tended to be low (dy/dx: -0.04, 95%CI: -0.08-0.01 in 2015; dy/dx: -0.07, 95%CI: -0.11-0.04 in 2016). This finding can encourage policymakers to manage coastal areas with green infrastructure in the post-disaster reconstruction sustainably.

Evidence suggests a positive effect of dog ownership on physical activity. However, most previous studies used self-reported physical activity measures. Additionally, it is unknown whether owning a dog is associated with adults' sedentary behaviour, an emerging health risk factor. In this study, physical activity and sedentary behaviour were objectively collected between 2013 and 2015 from 693 residents (aged 40-64 years) living in Japan using accelerometer devices. Multivariable linear regression models were used, adjusted for several covariates. The means of total sedentary time and the number of long (≥ 30 min) sedentary bouts were 26.29 min/day (95% CI - 47.85, - 4.72) and 0.41 times/day (95% CI - 0.72, - 0.10) lower for those who owned a dog compared to those not owning a dog, respectively. Compared with non-owners, dog-owners had significantly higher means of the number of sedentary breaks (95% CI 0.14, 1.22), and light-intensity physical activity (95% CI 1.31, 37.51). No significant differences in duration of long (≥ 30 min) sedentary bouts, moderate, vigorous, and moderate-to-vigorous-intensity physical activity were observed between dog-owners and non-owners. A novel finding of this study is that owning a dog was associated with several types of adults' sedentary behaviours but not medium-to-high-intensity physical activities. These findings provide new insights for dog-based behavioural health interventions on the benefits of dog ownership for reducing sedentary behaviour.

Since the emergence of the COVID-19 pandemic, the use of face masks by healthy individuals for prevention has been attracting public attention. However, efficacy depends on proper usage. We set out to determine the prevalence of wearing masks to prevent COVID-19 and compliance with appropriate measures for the correct use of face masks among the general public in Japan where wearing medical masks is a "cultural" normality. This cross-sectional study was based on an internet-based survey completed by 2141 people (50.8% men, aged 20-79 years) who were selected among registrants of an Internet research company between 1 April and 6 April 2020. Participants were asked to indicate how often they wore masks for prevention and to what extent they practiced appropriate measures suggested by the World Health Organization. The prevalence of wearing masks was 80.9% and compliance rates with appropriate measures ranged from 38.3% to 83.5%. Only 23.1% complied with all recommendations. Compliance rates were overall low in men and persons with low household incomes. Our results, hence show that many citizens implement inaccurate measures when using face masks. Therefore, providing guidance on correct usage is essential when encouraging the use of face masks to prevent COVID-19.

OBJECTIVES: To clarify changes in the implementation of personal protective measures among ordinary Japanese citizens from the early phase of the COVID-19 outbreak to the community transmission phase. METHODS: This longitudinal, internet-based survey included 2141 people (50.8% men; 20-79 years). The baseline and follow-up surveys were conducted from February 25-27, 2020, and April 1-6, 2020, respectively. Participants were asked how often they implemented the five personal protective measures recommended by the World Health Organization (hand hygiene, social distancing, avoiding touching the eyes, nose and mouth, respiratory etiquette, and self-isolation) in the baseline and follow-up surveys. RESULTS: Three of the five personal protective measures' availability significantly improved during the community transmission phase compared to the early phase. Social distancing measures showed significant improvement, from 67.4% to 82.2%. However, the prevalence of avoiding touching the eyes, nose, and mouth, which had the lowest prevalence in the early phase, showed no significant improvement (approximately 60%). Multivariate logistic regression analysis revealed that men and persons of low-income households made fewer improvements than women and persons of high-income households. CONCLUSIONS: The availability of personal protective measures by ordinary citizens is improving; however, there is potential for improvement, especially concerning avoiding touching eyes, nose, and mouth.

Background There are spatial disparities in cardiovascular disease (CVD) mortality related to area‐level socioeconomic status (SES) disadvantage, but little is known about the spatial distribution of CVD mortality according to built environment factors. We examined joint associations of neighborhood walkability attributes and SES with CVD mortality rates through linkage of Japanese national data sets. Methods and Results National data were used from the 1824 municipalities (of the 1880 potentially eligible municipalities) across Japan. The outcome was mortality from CVD for a 5‐year period (2008–2012) for each municipality. A national index of neighborhood deprivation was used as an indicator of municipality‐level SES. A national walkability index (based on population density, road density, and access to commercial areas) was calculated. Compared with higher SES municipalities, relative rates for CVD mortality were significantly higher in medium SES municipalities (relative rate, 1.05; 95% CI, 1.02–1.07) and in lower SES municipalities (relative rate, 1.09; 95% CI, 1.07–1.12). There were walkability‐related gradients in CVD mortality within the high and medium SES areas, in which lower walkability was associated with higher rates of mortality; however, walkability‐related CVD mortality gradients were not apparent in lower SES municipalities. Conclusions CVD mortality rates varied not only by area‐level SES but also by walkability. Those living in areas of lower walkability were at higher risk of CVD mortality, even if the areas have a higher SES. Our findings provide a novel element of the evidence base needed to inform better allocation of services and resources for CVD prevention.

Although associations between neighborhood socioeconomic conditions and health have been well established, their geographical scope is mostly limited to Western societies, while multilevel studies in the non-Western context (e.g., Japan) are limited to specific cities/regions within countries. This consequently limits the external validity of the findings. To fill the gap, this study examined the associations between neighborhood socioeconomic conditions and health-related indicators by using nationwide cross-sectional data in Japan. Individual data was collected from a nationwide online survey conducted in 2015 (n = 4593). Self-rated health, mental distress (Kessler Psychological Distress Scale: K6), smoking, and physical activity were analyzed in relation to neighborhood conditions. Analyses of multilevel logistic regression models were done using the Areal Deprivation Index (ADI) with population density as the neighborhood-level independent variable. After adjusting for individual covariates, ADI showed significant positive associations with poor self-rated health (odds ratio for one standard deviation increase and 95% confidence interval: 1.09, 1.00-1.19), mental distress (1.09, 1.02-1.16), current smoking (1.11, 1.03-1.19), and physical inactivity (1.11, 1.04-1.18). Population density was not associated with the four dependent variables. Analyses of the nationwide survey data in Japan showed that neighborhood socioeconomic conditions were independently associated with multiple health statuses and behaviors. These analyses may contribute to generalizing existing findings. Lastly, the results indicate the importance of neighborhood socioeconomic conditions in reducing health disparities in Japan.

OBJECTIVES: To clarify the implementation status of personal protective measures by ordinary citizens in Japan during the coronavirus disease 2019 (COVID-19) outbreak. METHODS: This was a cross-sectional study based on internet-based survey. A total of 2400 people (50% male: 20-79 years) were selected between February 25 and 27, 2020, from registrants of an Internet research company, to complete a questionnaire. Participants were asked to indicate how often they implemented the following five personal protective measures recommended by the World Health Organization (hand hygiene, social distancing measures, avoiding touching the eyes, nose and mouth, respiratory etiquette, and self-isolation). In addition, the participants responded to questions regarding the daily frequency of hand hygiene events. RESULTS: The prevalence of the five personal protective measures ranged from 59.8% to 83.8%, with the lowest being avoiding touching the eyes, nose, and mouth. In total, 34.7% implemented all personal protective measures. The median daily hand hygiene events were 5 per day (25th percentile, 75th percentile: 3,8). CONCLUSIONS: The protective measures implemented by ordinary citizens are insufficient and further public awareness activities are required.

Background: Self-isolation is an important personal protective measure in inhibiting the transmission of coronavirus disease 2019 (COVID-19) as people carry out economic and social activities amid its spread. Yet few studies have clarified the actual implementation status of self-isolation during an outbreak. This study aimed to reveal the actual implementation of self-isolation among Japanese workers during the COVID-19 outbreak and the factors inhibiting this measure. Methods: This was a cross-sectional study based on an internet survey completed by 1,226 workers (60.0% men) living in 7 prefectures (i.e., Tokyo, Kanagawa, Saitama, Chiba, Ibaraki, Tochigi, and Gunma) who were selected among registrants of an Internet research company, between May 12 and 17, 2020. Participants were asked whether they had experienced fever or other cold symptoms between February 17, 2020 and the date of the survey. Those who responded affirmatively were asked where they had visited (e.g., hospital, work, and shopping for groceries or necessities) to clarify whether they had left the house within 7 days after symptom onset. We performed multivariate logistic regression analysis to clarify the relationship between going to work within 7 days after symptom onset and both sociodemographic factors and employment-related constraints. Results: Of the survey participants, 82 had experienced fever or other cold symptoms (6.7%). Among these participants, 51 (62.2%) went to work within 7 days after symptom onset. A mere 17.1% practiced strict self-isolation. Multivariate logistic regression analysis revealed that those living outside the metropolitan area (i.e., Ibaraki, Tochigi, and Gunma), working as a company employee, and being unable to work from home were associated with going to work within 7 days after symptom onset. Conclusions: The prevalence of strict self-isolation among participants who experienced cold-like symptoms during the COVID-19 outbreak was extremely low, and 62.2% of these participants went to work within 7 days after symptom onset. This study highlights the need for further public awareness regarding self-isolation and countermeasures against factors that obstruct it.

There is a dearth of evidence about how high-density living may influence dog-walking behaviour. We examined associations between neighbourhood built environment attributes and dog-ownership and dog-walking behaviour in Japan. Data from 1058 participants were used. The dog-ownership was 18.8%. All neighbourhood built attributes (excluding availability of parks) were negatively associated with dog-ownership. Among dog-owners, these same attributes were positively associated with any dog-walking in a usual week and with achieving 150-min per week of physical activity through dog-walking alone. These findings provided evidence on the importance of neighbourhood built environment attributes on dog-ownership and dog-walking behaviour in dense and compact areas. The urban design and public health implication of these findings is that the built environment attributes in high-density living areas may have different impacts on dog-ownership and dog-walking: while living in a walkable neighbourhood may not be conducive to dog-ownership, it may support dog-walking in such areas. Programs targeting dog-owners in high-density areas might be needed to encourage them to walk their dogs more. If successful, these programs could contribute to higher physical activity levels among dog-owners.

OBJECTIVES: The aims of this study were to examine (a) associations of two metric and space syntax measures of street layout with the cognitive function of Japanese older adults and (b) the extent to which objectively assessed physical activity mediated such associations. METHODS: Cross-sectional data from 277 older adults who lived in Japan were used. Street layout attributes were objectively calculated for each participant's geocoded home location. The Mini-Mental State Examination was used to evaluate cognitive function. Physical activity was objectively assessed with accelerometers. RESULTS: There was a statistically significant negative association between street integration and the odds of having cognitive impairment. Objectively assessed physical activity did not attenuate this relationship. CONCLUSIONS: Our findings provide unique evidence regarding the importance of the topological aspects of street layouts in (re)designing neighborhoods to support mental illness.

AIM: We examined the relationships of objectively-measured walkability with accelerometer-measured activity patterns including bout-specific moderate-to-vigorous physical activity (MVPA), light-intensity physical activity (LPA) and sedentary behavior in older Japanese adults. METHODS: This cross-sectional study included 450 men and women (mean age 74 years) who were randomly selected from a resident registry of each municipality (Bunkyo, Fuchu and Oyama city). Neighborhood walkability was assessed using geographic information system data and activity patterns by a validated accelerometer (Active style Pro HJA-350IT). MVPA was assessed as overall (all minutes), short-bout (<10 min) and long-bout (≥10 min). We used analysis of covariance to examine environmental relationships with the three MVPA measures, LPA and sedentary behavior by quartiles of walkability, adjusting for accelerometer wear time and sociodemographic, behavioral and health-related factors. RESULTS: In total, 27% of participants achieved ≥150 min/week of long-bout MVPA. Walkability was not associated with overall MVPA (Q1 = 35.0, Q2 = 31.9, Q3 = 31.4, Q4 = 34.2 min/day) Older adults living in low-walkability areas significantly accumulated more short-bout MVPA (Q1 = 27.2, Q2 = 22.1, Q3 = 20.1, Q4 = 20.5 min/day) and LPA (Q1 = 346, Q2 = 311, Q3 = 289, Q4 = 284 min/day), but less sedentary behavior (Q1 = 479, Q2 = 520, Q3 = 544, Q4 = 544 min/day) than those living in high-walkability areas. CONCLUSIONS: Those living in low-walkability areas accumulated more LPA and short-bout MVPA. These activities might be helpful targets for initiatives to promote physical activity among older adult residents of low-walkability areas. Geriatr Gerontol Int 2019; 19: 861-867.

Audits have been used to provide objective ratings of neighborhood environments. Physical audits, however, are time- and resource-intensive. This study examines the efficiency and reliability of virtual auditing using Google Street View and crowdsourcing to conduct walkability audits of streets in Japan. Overall, 830 street segments were physically and virtually audited by two trained auditors; 300 untrained crowdworkers also virtually audited 3 street segments. Statistical analysis found good inter-source and inter-rater reliability. This study helps establish crowdsourced virtual auditing as a valuable method of measuring neighborhood walkability, reducing audit costs as well as enabling large-scale auditor recruitment while maintaining reliability.

BACKGROUND: Individuals residing in more deprived areas with a lower diet quality might have a higher mortality risk. We aimed to examine the association between deprivation within an area and all-cause mortality risk according to diet quality. METHODS: We conducted a population-based prospective study on 27,994 men and 33,273 women aged 45-75 years. Neighborhood deprivation was assessed using the Japanese areal deprivation index (ADI). Dietary intakes were assessed using a validated 147-item food frequency questionnaire. RESULTS: Individuals residing in the most deprived area had the lowest dietary scores. During the 16.7-year follow-up, compared to individuals with a high quality diet residing in the least deprived area, individuals with a low quality diet had a higher risk of mortality according to increment of ADI (p trend = 0.03); the multivariate-adjusted hazard ratio (95% confidence interval) was 1.09 (0.999-1.19), 1.17 (1.08-1.27), and 1.19 (1.08-1.32) in those residing in the lowest through the highest third of ADI, respectively. However, individuals with a high quality diet had no significant association between ADI and mortality. CONCLUSION: A well-balanced diet may prevent early death associated with neighborhood socioeconomic status among those residing in highly deprived areas.

Abstract. Census data are widely available in many countries and are useful in describing socio-economic structures in a map at an administrative unit level. Multiple variables in census data can be investigated, however, selecting a large number of variables often leads to confusion and makes it difficult to discern which should be considered. Correlation analysis is often applied to measure the degree of association of a pair of variables, while a correlation matrix is used to summarize relationships amongst multiple variables at the same time. Although both provide important metrics, the spatial configuration of the data is not taken into account. For the purpose of mapping, it is often of interest to highlight the correlative relationship between a pair of variables across space in order to deal with any spatial heterogeneity hidden in the data. In this sense, geographically weighted correlation and partial correlation analyses have been proposed to map spatial variations of correlations in a spatial data set. The geographically weighted approach uses a moving-window kernel running across geographical space and calculates a statistical model or summary statistic with distance-decayed weighted data. The critical issue of mapping such correlation relationships amongst multiple variables is the large number of resultant maps produced. If we are interested in correlations amongst 100 variables, the correlation matrix has the dimension of 100 by 100, while 4,950 correlation maps are produced when we investigate local correlation relationships. Furthermore, the degree of scale (localness) which is an important parameter to understand the local correlative relationship should be explored. To this end, the purpose of this study is to build an interactive mapping system for visualizing spatial variations of correlative relationships amongst multivariate variables in big census data. This system is built on Shiny in R and an R package for calculating the geographically weighted correlation and partial correlation coefficients across multiple variables (https://github.com/naru-T/GWpcor) is implemented behind this system for analyses. We use the national census data set for 2005 with 204 variables regarding socio-economic structures in 23 wards in Tokyo with 3,134 administrative units as a case study. The system implements geographically weighted correlation and partial correlation analyses with varying scale parameters and produces an interactive spatial surface of the correlation coefficient. We demonstrate how our interactive mapping system enables users to achieve quick visualization of correlative relationships amongst multivariate census data which can be selected and changed easily from pull-down lists (Figure 1). Such a user-friendly interactive mapping system proposed in this study will help those who need to understand the spatial relationships of the data that is being mapped. This study is supported by ROIS-DS-JOINT (006RP2018).

PURPOSE: The purposes of this study were to examine associations between objectively measured walkable urban design attributes with Japanese older adults' body mass index (BMI) and to test whether objectively assessed physical activity and sedentary behavior mediated such associations. DESIGN: Cross-sectional. SETTING: Matsudo City, Chiba Prefecture, Japan. PARTICIPANTS: Participants were 297 older residents (aged 65-84 years) randomly selected from the registry of residential addresses. MEASURES: Walkable urban design attributes, including population density, availability of physical activity facilities, intersection density, and access to public transportation stations, were calculated using geographic information systems. Physical activity, sedentary behavior, and BMI were measured objectively. ANALYSIS: The relationships of walkable urban design attributes, Walk Score®, and BMI were examined by multiple linear regression with adjustment for covariates in all models. Mediation effects of the physical activity and sedentary behavior variables in these relationships were tested using a product-of-coefficients test. RESULTS: Higher population density and Walk Score® were associated with lower BMI. Light and moderate-to-vigorous physical activities partially mediated the relationships between these walkable urban design attributes and BMI. CONCLUSIONS: Developing active-friendly environmental policies to (re)design neighborhoods may not only promote active transport behaviors but also help in improving residents' health status in non-Western contexts.

Despite the wide variety of international evidence on the relationship between the socioeconomic status (SES) and health outcomes, less is known about the association between SES and healthcare provider practices. We assessed whether patients with a closed hip fracture were treated differently by hospital physicians according to the SES of their residential areas in Japan. Hip fracture is a common cause of hospitalization among the elderly, but the relationship between SES and hip fracture treatment remains unknown in Japan. We employed the Diagnosis Procedure Combination (DPC) database from April 2011 to March 2014. SES of the patient's residential area was estimated using Census-derived areal deprivation index (ADI). We performed a cross-sectional study of national claims data and analyzed it using cross-classified multilevel models. We used two outcome measures: (i) whether the patient received an operation or was treated by watchful waiting; and (ii) number of waiting days until operation following admission. We identified 95,011 patients admitted to 1,050 hospitals. Of these, 85,480 patients underwent surgery. Low SES of residential areas was not correlated with the chance of undergoing surgery (P = 0.15) but was weakly correlated with longer waiting days (coefficient, 0.03; 95% confidence interval, -0.01 to 0.06; P = 0.08). The difference of waiting days between maximum (10.4) and minimum ADI (-4.0) was marginal (0.39 days). The results indicate the SES of patient's residential area does not affect the decision of surgical treatment for hip fracture and has ignorable impact on waiting days from hospital admission to surgery.

Degraded mangrove areas have increased and become a critical issue in Riau, Indonesia. Thus, local people are required to use and manage the remaining natural resources sustainably. In this study, interviews and network analysis were applied to identify the connections and strengths of mangrove ecosystem functions and services, and human wellbeing which this ecosystem brings to three ecotourism villages. As a result, the strength of connections and the component of ecosystem functions, services, and human wellbeing, which local people perceived varied among the villages. An ecosystem assessment which encompasses natural resource management and human wellbeing can be a useful approach for sustainable community-based management.

OBJECTIVES: This study investigated the longitudinal association between changes in older adults' physical activity and neighborhood walkability measured by geographic information systems (GISs, (ArcGIS, ESRI Inc., Redlands, CA, USA)). METHODS: A mail survey was conducted for Japanese older adults who were randomly selected from three different settlement types. Data on walking, total moderate to vigorous physical activity (MVPA), and sociodemographic characteristics were collected at baseline (in 2010) and follow-up (in 2015). Multiple linear regression analyses were employed to assess the association between MVPA change and neighborhood walkability, adjusted for potential confounders. Effect sizes for independent variables on MVPA change were estimated. RESULTS: Data from 731 community-dwelling older adults (43.7% women) were analyzed. During the follow-up, older adults' MVPA was reduced by 94.4 min/week (-14.2%) on average (675.5 and 579.9 min/week in 2010 and 2015, respectively). Overall, older adults living in highly walkable areas showed a smaller reduction than those in low walkable areas (beta: 99.7 min/week, 95% confidence interval: 28.5⁻171.0). Similar associations were observed among those in the urban and suburban area, but not in the rural area. Walkability had larger effect sizes for explaining MVPA change than demographic characteristics. In addition, the findings for walking were similar to MVPA. CONCLUSION: Neighborhood walkability mitigated the 5-year reduction of walking and total MVPA among older adults, especially in urban areas.

Evidence about the impacts of the physical activity environment on adults' weight in the context of Asian countries is scarce. Likewise, no study exists in Asia examining whether Walk Score ® -a free online walkability tool-is related to obesity. This study aimed to examine associations between multiple physical activity environment measures and Walk Score ® ratings with Japanese adults' body mass index (BMI). Data from 1073 adults in the Healthy Built Environment in Japan study were used. In 2011, participants reported their height and weight. Environmental attributes, including population density, intersection density, density of physical activity facilities, access to public transportation, and availability of sidewalks, were calculated using Geographic Information Systems. Walk Scores ® ratings were obtained from the website. Multiple linear regression analysis was conducted to examine the association between each environmental attribute and BMI. Adjusting for covariates, all physical activity environmental attributes were negatively associated with BMI. Similarly, an increase of one standard deviation of Walk Score ® was associated with a 0.29 (95% confidence interval (CI) of -0.49--0.09) decrease in BMI. An activity-friendly built environment was associated with lower adults' BMI in Japan. Investing in healthy community design may positively impact weight status in non-Western contexts.

Geographical crime prediction have been the focus of much research in western countries over the past decade and crime prediction systems are already in use several countries including Japan where a prefectural police department have recently introduced a certain system. However there has been no prior research into this field in Japan. This paper presents a systematic review of geographical crime prediction and discusses their relevance to the Japanese context. We identify four categories of geographical crime prediction methods: (1) surveillance of space-time clusters of crime; (2) estimation of crime intensity based on space-time interaction; (3) prediction of crime risk based on environmental factors; and (4) prediction of crime numbers/possibilities. These categories are based on established theories and have been developed independently of each other. Finally, we suggest directions for future developments of this research field in Japan.

Previous studies revealed that in terms of the stem height growth, containerised seedlings with an average height:diameter ratio(HDR)of ca. 60 are superior to conventional bare-root seedlings and containerised seedlings with an average HDR of ca. 100 are inferior to conventional bare-root seedlings. In this study, we focused on the correlation between the stem growth and HDR in individual seedlings. We measured the stem growth of 2-year-old containerised seedlings and 3-year-old conventional bare-root seedlings for four growth seasons. In each of the growth seasons, HDR showed a negative correlation with stem height growth rate and a positive correlation with the stem radial growth rate of an individual seedling; the strongest correlation was observed in the first and second growth seasons. Therefore, the seedling with a high HDR allocated resources to stem radial growth rather than to height growth. Regarding the stem height growth, we analysed the sequential data for four growth seasons using a linear mixed effects model. HDR showed a negative correlation with the stem height growth. In conclusion, high HDR had negative effects on not only the relative height growth rate but also on the actual height growth.

Objectives To examine the relationship between dietary diversity and food access among elderly living alone. Methods In September 2013, a cross-sectional study using a self-administered questionnaire was conducted with 4,348 elderly aged 65–89 years, living in A city in Saitama Prefecture. The subjects answered about their health conditions, frequency of food consumption, difficulty of food store access, social support, food preparation, and so on. The response rate was 59.6%. The dietary diversity score (DDS) was calculated as the number of food groups consumed in a day (0 to 10). The DDS was validated by its association with independence and health status of the elderly. As indicators of food access, objective food access was measured using a geographic information system (GIS), and subjective food access was measured by the questionnaire. Responses of 1,043 subjects (452 male and 591 female) were analyzed after excluding those who live with others in an actual household composition. We classified the subjects into two groups according to the DDS: low group (three or less) and high group (four or more). Multiple logistic regression analyses were conducted using the DDS groups as the dependent variable, and subjective food access and other factors as independent variables, adjusting for age, income, subjective economic status, education, and frailty status. Results The number of subjects in each group were as follows: low=107 (23.7%), high=345 (76.3%) for males, high=263 (44.5%), low=328 (55.5%) for females. A multiple logistic regression analysis showed that the difficulty in subjective food store access was associated with a low DDS in males [OR=4.00, 95% CI (1.36–11.82)] as well as in females [OR=2.24, 95% CI (1.11–4.51)]. Further, for females, social support and preparation of supper by oneself were significantly associated with their DDS. No significant relationships were found between objective food store access and DDS in both males and females. Conclusion The DDS was strongly associated with subjective food store access among the elderly living alone. For females, social support and meal preparation skills were also suggested as important factors affecting their DDS.

This study examined how the implementation of a disaster mitigation education program for high school students in a geography course contributed to the students' learning of geography and understanding of flood risks in the vicinity of the school district. The education program aimed to improve students' understanding of flood risks through disaster mitigation mapmaking activities that engaged the students in learning about local landforms and area survey methods. The mapmaking activities comprised classroom instruction, fieldwork, and presentations on the maps. Twenty-two students from the Kyoto Prefectural Nantan High School participated between July and October 2011. Questionnaire data from the students, the disaster mitigation maps, and manuscript notes for the presentations were analyzed; the results indicate that the mapmaking activities were extremely effective at improving students' understanding regarding the relationship between landforms and flood risks. This education program could be applied to improving students' understanding of flood risks in other areas. Furthermore, teaching students to think in geographical terms and draw on geographical perspectives in examining flood risks can facilitate the development of problem-solving abilities.

An increasing body of literature has focused on neighborhood environments as one of the factors that determine health. Nevertheless, the research that has been conducted in Japan in this regard and that at a national scale have been very limited. In this study, statistical analysis was conducted to determine whether health-related quality of life (HRQOL) correlates with particular characteristics of the neighborhoods that people live in. Multilevel analysis was applied to data from the Japanese General Social Surveys of 2010 (n=2,326) to examine the associations of the three composite scales of HRQOL (SF-12) with both perceived and objective measurements of neighborhood environments. The results indicate that respondents who expressed positive perceptions of their neighborhood were more likely to have better levels of HRQOL. However, the objective measures of neighborhood environments were not independently associated with HRQOL, which indicates that the connections between health and place of residence are fairly complex.

This study examined the determinants of spatial variation of host-seeking vector mosquitoes of Japanese encephalitis, Culex tritaeniorhynchus, and malaria vector mosquitoes, the Anopheles sinensis group, to estimate the distribution of mosquito habitats along the eastern coast of Lake Biwa, Japan. Data for the statistical analysis were obtained from a mosquito survey conducted using 20 traps during May to October 2009. For explanatory variables, we constructed a dataset of land cover in the study area by classifying satellite images of ALOS. We employed partial least squares (PLS) regression to analyze the relationship between the number of mosquitoes collected and land cover composition around trap sites. The results indicate that the number of host-seeking Cx. tritaeniorhynchus was larger when the areal components of the rural-agricultural landscape (e.g., paddy fields) were larger around the trap sites. For the An. sinensis group, the number of host-seeking mosquitoes was larger when the areal components of the wetland landscape (e.g., water bodies and reed beds) were larger around the trap sites. The potential habitat maps derived by fitting the PLS regression model into a GIS environment indicated that suitable habitats for Cx. tritaeniorhynchus are mainly distributed across plains and that for the An. sinensis group are concentrated around water bodies. We interpreted these results to mean that the distribution of the estimated potential habitats of host-seeking mosquitoes reflects the behavioral response of mosquitoes to spatially heterogeneous environments.Thus, the mapping of potential habitats estimated using datasets of vector mosquitoes and land cover may provide fundamental information for planning effective control strategies for vector mosquitoes.

Objectives Although factors associated with falls might differ between men and women, no large-scale studies were conducted to examine the sex difference of risk factors for falls in Japanese elderly. The purpose of this study was to examine fall risk factors and sex differences among community-dwelling elderly individuals using a complete survey of the geriatric population in Kameoka city. Methods A self-administered questionnaire survey was conducted with 18,231 community-dwelling elderly individuals aged 65 years or over in Kameoka city, Kyoto Prefecture, between July and August 2011, excluding people who were publicly certified with a long-term care need of grade 3 or higher. The questionnaire was individually distributed and collected via mail. Out of 12,159 responders (recovery rate of 72.2%), we analyzed the data of 12,054 elderly individuals who were not certified as having long-term care needs. The questionnaire was composed of basic attributes, a simple screening test for fall risk, the Kihon Check List with 25 items, and the Tokyo Metropolitan Institute of Gerontology (TMIG) index of competence with 13 items. These items were grouped into nine factors: motor function, malnutrition, oral function, houseboundness, forgetfulness, depression, Instrumental Activity of Daily Living (IADL), intellectual activities, and social role. Results Of all the respondents, 20.8% experienced falls within the last year, and 26.6% were classified as having high fall risk. Fall risk increased with age in both sexes, and risk in all age groups was higher for women than for men. All factors were significantly associated with fall risk in both sexes. After controlling for these factors, a significant relationship was found between fall risk and motor function, malnutrition, oral function, forgetfulness, depression, and IADL in men and motor function, oral function, forgetfulness, depression, and IADL in women. The deterioration of motor function was associated with three-times-higher risk than non-deterioration of motor function. In addition, significant interaction was found in sex×malnutrition, oral function, IADL, and intellectual activities; malnutrition and low oral function were stronger factors in men than in women; and IADL and intellectual activities were stronger factors in women than in men. Conclusion One in five community-dwelling independent elderly individuals experienced falls in the last year, and one in four had high fall risk. We found a significant relationship between fall risk and the nine factors, particularly deterioration of motor function in both sexes. Sex difference was observed for fall risk factors; therefore, a sex-specific support policy for fall prevention is necessary.

11This study produces small-area estimates of socio-economic conditions in Osaka city, Japan using a spatial microsimulation method. Using data derived from the 'Comprehensive Survey of Living Conditions' and 'Population Census of Japan', we produce household-level synthetic microdata. Monthly expenditure, as a proxy of household living conditions, is then mapped in order to examine spatial inequalities. The accuracy of these synthetic microdata is validated by (1) fitting to constraining census tables, (2) assessing variances in fitting measures and expenditure on the basis of 100 simulations, and (3) fitting at the aggregated level. The results show that, except for several small areas that have skewed population distributions, almost all small areas achieve high accuracy compared with constraining census tables. In addition, the degree of accuracy does not change according to the simulation, while variances in estimated expenditure are small enough. The examination of estimated expenditure at the aggregated level confirms that the estimate mostly agrees with the findings of the Comprehensive Survey of Living Conditions. Differences can be explained by missing samples among household heads aged 20-30 years old. Spatial microsimulation can correct such sampling bias in the process of synthetic microdata construction. The spatial distribution of socio-economic conditions estimated by tabulating synthetic microdata is therefore beneficial for analyses of the relations between individuals and neighbourhood health status, crime rates, and consumer behaviour.

Disparities in quality of life including health status have often been associated with socio-economic status, particularly in terms of income-related measures. In this paper, we examine whether geographical inequalities at the neighbourhood level in the population health are determined by place-based contextual effects that cannot be explained by compositional effects of individualistic income levels in Japan. By integrating Japanese General Social Survey 2000-2003 data with social area typologies/geodemographics (Moisac Japan), we explore the contextual effects that may regulate geographical and income disparities in self-rated health measures using multi-level modelling. First, we confirm the existence of significant self-rated health variations between social area typologies even after equivalised income compositions are controlled for at the individual level. These variations are particularly large among low-income groups compared with middle- and high-income ones. Second, while some health disparities between social area typologies correspond to socio-economic segregation, health disparities between income groups are wider in neighbourhoods situated in central parts of metropolitan regions. These findings indicate that the place-based contextual effects, so-called neighbourhood effects characterised by social areas in Japan, could be crucial factors regulating both geographical and social disparities in the health status of the Japanese population.

This study examines how the safety and security mapmaking workshop in Shino town of Kameoka city, conducted by the community association in January 2009, contributed to environmental interventions by changing the local environment for promoting safety in the area. Shino town is designated as the model area by the Kameoka city government for promoting safety, since community activities to advance safety are actively conducted here. The data for this study were collected through fieldwork surveys from August to September 2010 in 259 sites designated as dangerous/hazardous in the 2009 workshop. We found that the mapmaking workshop directly and indirectly led to environmental interventions by the community association. The mapmaking workshop also shows a spillover effect, as seen in environmental interventions made among community residents, owing to the distribution and use of the safety and security maps made after the workshop. The small number of such activities shows, however, that the environmental interventions owing to the mapmaking workshop are hard to be attained, even in Shino town, where the designated community association characterised by its active and long community activities is able to easily receive official support from the local government.

The response rate is an important indicator of the reliability and validity of a sampling survey. Recently in Japan, especially since 2005, major social surveys have experienced a substantial decline in response rates, and researchers have become concerned about the worsened survey environment. In this paper, we sought to examine the regional differences in survey response rates and their individual and geographic determinants. The data we used were individual data on survey responses to the national representative sample survey with face-to-face interviews in Japan (JGSS: Japanese General Social Surveys) in 2005 and 2006. We distinguished the two-stage process of survey response: (a) whether the investigator was able to meet with those surveyed; and (b) whether they participated in the survey. The differences were then analyzed based on individual and regional characteristics. Large regional differences, measured by the degree of urbanization and neighborhood typology, were observed in both processes. This means that the regional difference in the response rate was also large, because the rate can be obtained by multiplying (a) by (b). We also performed multivariate analysis adjusted for individual attributes such as age, gender, and house type and considering the clustering nature of the samples within the same surveyed area (i.e., multilevel analysis). The results showed that the regional differences in the survey response remained statistically significant, although they were partially explained by the respondents' individual attributes. The current study elucidated that the survey response rate to a face-to-face interview is determined by geographic factors as well as individual attributes of the respondents. Additionally, we confirmed regional variations in the survey response rate between surveyed areas which cannot be explained by the degree of urbanization and neighborhood type, indicating the existence of “local survey environments” that have geographically unique and contextual factors that affect the response rate.

This paper aims to assess the renovation and conservation policy pertaining to historical structures in Kyoto. It adopts a tourism demand estimation approach in terms of the contingent behavior of potential tourists to the ancient capital of Kyoto, one of the most popular tourist cities in Japan. Specifically, the regional spillover effects of the policy are assessed on the basis of regional differences in visit frequency to Kyoto before and after the implementation of the policy. This follows the assumption that historical structures in Kyoto are renovated and conserved on the basis of the policy. The analytical data comprises contingent behavior data, which was collected through the online questionnaire survey on the Yahoo! Research website. Respondents were aged 20 or above (supplied by Yahoo! Japan Corporation). The models of visit frequency were estimated using the zero-inflated Poisson (ZIP) regression model with the random intercept where the dependent variable was visit frequency and the independent variables were residence region, age, sex, household size, and household income. The results of the modeling, with all above variables controlled, shows that the visit frequency is highest in the Kinki region, from where, compared to other regions in Japan, Kyoto can be reached easily; the ease of travel tends to decline progressively with the increase in distance from Kyoto. The renovation and conservation policy of historical structures is also estimated to increase the number of tourists from across the nation to Kyoto, particularly in the Kinki region, which is close to Kyoto and contains one of the most densely populated areas in Japan, Keihanshin Metropolitan Area. However, the estimated model shows that the increase in the visit frequency per unit of population is relatively high in areas distant from Kyoto (e.g., Kyushu, Hokkaido, and Tohoku region).

This paper is aimed at examining the association between the degree of urbanization/suburbanization and the levels of social capital in quantitative terms. We performed a multilevel analysis for the data from JGSS (Japanese General Social Surveys) conducted in 2000-2003. The results showed that the respondents who resided in rural municipalities (i.e., the least urbanized areas) were more likely to belong to groups, for both vertical and horizontal types of organizations, compared to those who lived in the center of large metropolitan areas. However, no differences were seen between urban centers and suburbs within these metropolitan areas studied. In addition, the indicators of general trust and attachment to place did not exhibit significant associations with the index of urbanization! suburbanization. On the contrary, many individual attributes were related to social capital indices; suggesting that the individual/compositional factors may determine the levels of social capital more clearly than the regional/contextual factors. Since our study used the indicators of "global social capital", which do not refer to geographical aspects of social networks or trust, analyzing "local social capital" is necessary in future studies.

This study examined the causal structure of the willingness to use a web-based safety and security map for community safety and disaster prevention. Several evaluation studies on such web-based maps clarified some of their advantages and/or disadvantages by summarizing user evaluations. However, the previous studies did not show whether local citizens preferred a web-based map over a printed map for community safety and disaster prevention or which factors determined the willingness to use web-based maps. The analytical data for this study were collected through an interview survey of 44 individuals residing in the city of Kameoka, Kyoto prefecture. Since they tended to state greater willingness to use a web-based map compared with a printed map, a web-based map could contribute significantly to sharing community safety and disaster prevention information. Structural equation modeling of the willingness to use a web-based map also suggested that it is important to enable users to imagine clearly the possible uses of the mapping system as well as create an easily understood interface for enhancing the communication of community safety and risk information through a web-based map.

&emsp;This study explores how to use geospatial information for residential safety and security activities, such as patrolling a community, from the perspective of PPGIS. The study takes Shino-town, Kameoka City as a case study, where a neighborhood community association held a workshop in 2009 for residents to collect geospatial information for use in disaster prevention and daily security. Because they made a hard-copy “Safety-security Map,” we first converted it into a web-based map with functions that help a user prepare a walking route using Google Maps API. Using the web-based map, some Kameoka residents developed routes for patrolling the community. Then, we walked through the routes with them, conducting interviews on how they felt about risks and attractive features along the routes. &emsp;Analyzing the results of the field research and interviews, we identified substantial differences in risk perception and interest in the possibility of using web-based safety-security maps by local community residents. Compared to the male representative group of the residents' association, female members of the welfare commission and the PTA representative group were more interested in community safety and disaster prevention information, and the web-based map containing information. They hope to use the web-based map to exchange information among residents. Besides, they showed a keen interest in using the web-based map for walking exercise to raise their awareness of community-safety and disaster-prevention information on a daily basis. It is vital to integrate different interests and needs for safety-security geospatial information of local resident groups to carry out effective residential safety and security activities.

The aim of this paper is to examine regional differences in the prevalence of pollinosis by social area type in a geodemographics dataset by carrying out binomial logistic regression analysis on the 2002-2006 Japanese General Social Surveys (JGSS) data. The results indicate that people living in rural areas and working in the agriculture and forestry industries are less prone to contracting pollinosis, and people with a higher household income have a higher risk of contracting the disease compared to those with a lower household income. These findings are consistent with the hygiene hypothesis that sanitary environments impair normal development of immunity and increase the risk of contracting allergic diseases. This study also exemplifies the usefulness of geodemographics as a concise indicator of the local environment for explanatory analysis of environmental health risks of pollinosis.

This paper aims to build a spatiotemporal GIS database about boundaries of municipalities. The municipality is most popular spatial unit used for statistical data in Japan. However, because the boundaries of the municipalities often change, it is difficult to compare statistical data in two time points. This database allows us to obtain the boundary GIS data of municipalities at any given time point after 1970 and the correspondence table of municipalities between two time points through the web-based interface of this database. This database, named "Municipality Map Maker for Web (MMM4W)", facilitates the GIS analysis using the statistical data by municipalities with a temporal dimension.

Objectives : We studied physician partner testing (PT) practice and obstacles against PT in the clinical settings in Japan. Methods : Subjects were 513 physicians identified at HIV/AIDS sentinel hospitals. The questionnaire included demographics, current practices, factors for facilitating PT, experience in finding new HIV cases through PT, and information channels for PT. Results : Of physicians interviewed, 66％ did PT for all HIV cases, with 37％ finding 185 new HIV cases through PT. Physicians reported too little time for PT, together with a lack of legal authorization and standardized educational material. Of those interviewed, 78％ did PT orally. Conclusions : Detecting new HIV cases showed the effectiveness of PT in identifying and diagnosing HIV cases as early as possible in Japan. To expand PT legal authorization, standardized practices, and educational material all require development.

We examined the relationship between spatial variation in the number of vector mosquitoes of Japanese encephalitis, Culex tiritaeniorhynchus, collected by dry ice baited traps and the patterns of land use around each trap location. By using CDC miniature light traps enhanced with 1 kg of dry ice, we collected mosquitoes at 13 trap sites inside 3 cowsheds and 10 outdoor-trap sites distributed at 6 rural villages in Toyama Prefecture, Japan. Significant differences in the number of captured mosquitoes were observed among the trap sites. Multiple regression analysis was performed to explain the observed spatial variation in mosquito numbers among the 10 outdoor-traps by choosing a set of land use components and using the distance from the cowshed as predictors. Twelve “land use components” were distinguished and the proportion of area covered with each component was calculated within a circular area around each trap location. Four different radii of the circular area were used in the regression analysis and the best model explained 66.6% of the variation when the radius was 150 m long. The rural-agricultural landscape represented by paddy fields had the largest regression coefficient suggesting a strong association with the spatial variation in the number of mosquitoes captured by dry-ice baited traps.

BACKGROUND: Recent research has revealed the importance of neighborhood environment as a determinant of physical activity. However, evidence among elderly adults is limited. This study examined the association between perceived neighborhood environment and walking for specific purposes among Japanese elderly adults. METHODS: This population-based, cross-sectional study enrolled 1921 participants (age: 65-74 years, men: 51.9%). Neighborhood environment (International Physical Activity Questionnaire Environmental Module) and walking for specific purposes (ie, transportation or recreation) were assessed by self-report. Multilevel logistic regression analyses with individuals at level 1 and neighborhoods at level 2 were conducted to examine the association between environment and walking, after adjustment for potential confounders. RESULTS: Access to exercise facilities, social environment, and aesthetics were associated with total neighborhood walking. Odds ratios (95% CI) were 1.23 (1.00-1.51), 1.39 (1.14-1.71), and 1.48 (1.21-1.81), respectively. Regarding walking for specific purposes, social environment and aesthetics were consistent correlates of both transportation walking and recreational walking. Environmental correlates differed by specific types of walking and by sex. Transportation walking significantly correlated with a greater variety of environmental attributes. Sex differences were observed, especially for transportation walking. Bicycle lanes, crime safety, traffic safety, aesthetics, and household motor vehicles were significant correlates among men, while access to shops, access to exercise facilities, and social environment were important among women. CONCLUSIONS: Specific environment-walking associations differed by walking purpose and sex among elderly adults. Social environment and aesthetics were consistent correlates of both transportation walking and recreational walking. Improving these environmental features might be effective in promoting physical activity among elderly Japanese.

The aim of this review is to summarize the recent interdisciplinary interest in the relationship between health and place related to issues of geographical inequalities in health since the 1990s, mostly in the context of Anglophone literature, in order to identify meaningful research challenges applied to the context of Japan. There are several background factors which have directed this trend, including: (1) advanced GIS and spatial epidemiology techniques; (2) the emergence of the 'new' geography of health; and (3) the exploring of possibilities of environmental health interventions based on the philosophy of the 'new public health.' Referencing keywords of papers published in the influential journal in this field, Health & Place, we found that there is a clear accumulation of studies of "neighbourhoods" in contemporary settings of developed countries. Such studies broadly argue (1) that socially deprived people are likely to live in deprived/harmful areas, and (2) the kind of general environmental changes that can alter the ideal concept of 'healthy places' in the society. We also contextualized the neighbourhood research interest into categories of compositional effects by selective migration and housing, possible 'upstream causes' of social inequality related to relative income and the neo-materialist hypothesis, and historical transitions of 'healthy towns' in the relationship between public health and city planning concepts. Although the underlying context of the society and lifestyles in the reviewed Anglophone studies are often largely different from those of Japan, there is a large potential for conducting studies of geographical inequality in health in various research fields of geography and related disciplines in order to identify Japanese contextual effects and to propose effective environmental intervention schemes in the society. Particularly when we consider the fact that Japan is still one of the healthiest and most egalitarian nations in the world, conditions may be associated with geographical aspects of the society, such as less segregated social area formation. However, recent apprehension about rising social inequality and related social/geographical inequality problems has provoked us to learn lessons from other countries' experiences of (un) healthy neighbourhoods structured by globalization, social policy, and urban design.

This study examined how the residents determine to attend a workshop on making a safety and security map with resident participation by using logistic regression modeling concerning about whether a resident realized the information on the event in advance, and whether a resident who had realized it decided to join it. Although the notice on the workshop had been circulated in advance to every household registered in the neighborhood community association, our analysis shows that residents lacking regular social relationships with neighbors were less likely to realize the workshop event. It is also indicated that as well as regular social contacts with neighbors, perception on the risk of natural disaster would encourage a resident who realized the event to participate in it. These results imply caveats in planning such a resident-participatory event for promoting community safety.

The purpose of this study is to evaluate accessibility to cultural heritages in road blockade caused by earthquakes in Kyoto City. In order to predict accurate road blockade distributions, we construct a simulation model to estimate detailed attributes of each building by combining multiple data sets and thereafter simulate the collapses based on them. As a result, 8% of cultural heritages cannot be reached at all and another 8% at only 20% due to the blockade. These results suggest approximately 20% of cultural heritages are at high risk of being burned out by fire disasters and therefore, disaster mitigation strategies such as on-site fire extinguishers are needed.

Kyomachiya (traditional wooden townhouses) are one of the important elements characterizing the historical urban landscape of Kyoto. However, the rapid decrease in the number of kyomachiya and the modern urban landscape filled with high-rise buildings constructed after kyomachiya demolitions have been controversial. In recent years, the preservation of kyomachiya has become an urgent policy issue. This paper examines the determinants of the demolition of kyomachiya in the Nishijin district, one of the historical town centers of Kyoto. We used the results of kyomachiya facade surveys to conduct stepwise logistic regression analysis incorporating explanatory variables of three categories related to kyomachiya demolitions and land use changes: 1) characteristics (conditions and usage) of kyomachiya; 2) land use restrictions; and 3) neighborhood conditions (percentage of kyomachiya, high-rise buildings, and other land use types within a 25-m or 50-m radius). The examination of kyomachiya demolitions shows that 13% of the kyomachiya in the Nishijin district were demolished from 1998 to 2004, approximately 60% of demolished kyomachiya were rebuilt into modern townhouses, and 15% were transformed into apartment houses or commercial buildings. The spatial distribution of the demolitions was bipolarized: the ratio of demolitions was higher in areas where the density was lower, and vice versa. The results of binary logistic regression analysis show that the demolitions are determined by building type (detached/terraced), building conditions, vacancy, building height restriction, and neighborhood conditions. In addition, kyomachiya demolitions are negatively related to neighborhood conditions. The spatial extents of neighborhood conditions differ by land use type. We discuss the demolition of one kyomachiya induces another demolition due to the neighborhood effect. Therefore, it can lead to a spatially bipolarized pattern of demolitions. Further analysis based on multinomial logistic regression analysis shows that land use changes after demolitions are determined by land use restrictions, neighborhood conditions, and previous kyomachiya characteristics. In particular, detached and well-maintained kyomachiya located within a semi-industrial zone and in neighborhoods where the density of kyomachiya is already low are more likely to be transformed into modern townhouses. We conclude that, in a neighborhood where the number of kyomachiya is relatively low, the speed of kyomachiya demolitions increases locally so that the spatial pattern of the demolitions will be biased. Land use types after the demolitions are influenced by land use restrictions and neighborhood conditions as well as previous usages and conditions of kyomachiya. Therefore, the process of land use changes from kyomachiya occurs with both spatial and temporal linkages.

&emsp;To detect spatio-temporal pattern of crime clusters/hotspots, the possibilities of three-dimensional mapping methodologies for crime event data are explored using two approaches: three dimensional kernel-density mapping using a volume rendering technique and visualisation of cylindrical significant clusters that can be detected by space-time scan statistics. Both approaches are intended to visualise spatio-temporal domains with high densities of crime in a three-dimensional space composed of two geographical dimensions and one time dimension. The proposed three-dimensional mapping methodologies are evaluated through application to a dataset of snatch-and-run offences in Kyoto City during the period 2003-2004. The results are summarized as follows: &emsp;(a) Three-dimensional crime mapping enables effective visualisation of the geographical extents and duration of crime hotspots simultaneously. This method is particularly useful to identify geographical diffusion and movements of crime clusters/hotspots compared to traditional dynamic analyses of crime mapping using cross-sectional maps with arbitrary time intervals. &emsp;(b) In practice, the roles of three-dimensional kernel mapping and space-time scan statistics should be complementary. Space-time scan statistics provide clear-cut domains of crime clusters/hotspots that can be used for secondary analyses, such as evaluation of socio-environmental and temporal characteristics focusing on detected domains. However, we should note that the method assumes cylindrical geometrical-constrains of space-time domains. Three-dimensional kernel density mapping provides fuzzy domains with high densities of crime and a useful basis to assess the validity of the assumption of spatial scan statistics and to investigate detailed space-time sequences of crime clusters/hotspots. &emsp;(c) Empirical analyses of the snatch-and-run offence dataset in Kyoto City revealed constant clusters/hotspots during the study period in central Kyoto and around Kyoto Station as well as transient clusters/hotspots around several railway stations in the suburbs. Temporal differences of transient clusters show geographical movements of hotspots from the north to the south via the west. We also identified that outbreaks of snatch-and-run offences alternated between a pair of cluster areas. These results suggesting so-called displacement phenomena indicate the need to monitor crime events and effects of crime-preventive actions in a widespread space-time context.

&emsp;Virtual Kyoto is a virtual time-space created on a computer for the purpose of investigating the past, present and future of the historical city of Kyoto. Using the cutting-edge technologies in GIS and VR, we built Virtual Kyoto which is 4DGIS that comprise a series of 3DGIS at different points in time. Our 3D city modeling begins with the present Kyoto and then goes back to the past, including those soon after and before the World War II, the Taisho and Meiji eras, pre-modern Edo era and finally back to Heian era when the city of Kyoto was founded in late 8th century. &emsp;Creating Virtual Kyoto includes the following projects: a) Archiving geo-referenced materials such as current digital maps, old topographic maps, cadastral maps, aerial photos, picture maps, street photos, landscape paintings, archaeological sites data, and historical documents; b) Creating a database of all existing buildings including machiyas (traditional town houses), early modern buildings, shrines and temples including historical and cultural heritages; c) Creating 3D VR models of the above buildings; and d) Estimating and simulating land use and landscape changes over the study periods using aforementioned materials. &emsp;Virtual Kyoto is an infrastructure to place various digitally archived materials associated with the city, and to disseminate Kyoto's subtle and sophisticated forms of cultures and arts to the world over the Internet. The web-based system provides user-friendly interface to explore historical materials of cultures and arts in the geographical context of Kyoto with its historical landscapes. Virtual Kyoto should play a valuable role in the assistance for urban landscape planning of Kyoto as well as sending rich information about Kyoto to the world through the Internet.

In order to clarify spatial disparities of health in a Japanese urban geographic space, we examine transitions of mortality distributions in the Tokyo metropolitan area during 1980-2000. According to RII (relative index of inequality), geographic inequalities of health along geographic inequality of income level are wider for men than women, working age people than elderly population, and have slightly widened for all of the sex-age groups during the study period. While healthy regions have been extended in suburbs towards to the edge of the metropolitan area, unhealthy areas are spatially concentrated in peripheral parts and inner city areas. We discuss the trend and future of the geographic polarisation of health at the age of the end of suburbnisation and back-to-city movement" in the metropolitan area.

This study examined the causal structure forming willingness to pay (WTP) for historic landscape restoration from possible natural and man-made disasters in Kyoto. The result of structural equation modeling can be summarized as follows: (1) the respondents who recognize functions the historical landscape conserve the comfortable environment and the regional culture and history tend to have higher values to the landscape and are also aware of higher risks of natural disasters that could destroy the historical landscape. Such respondents having these evaluations stated higher WTP. (2) Kyoto residents tend to state higher WTP through direct and indirect pathways. The result suggests there is a strong regional effect on WTP reflecting Kyoto residents' affection on their daily environments and cultural-historical backgrounds. (3) The positive income effect on WTP consists of the direct effect based on paying capacity and the indirect effect on the basis of rich knowledge of culture and history.

This research integrates Geographical Information Systems (GIS) and Virtual Reality (VR) technologies to develop a 4D-GIS, ‘Kyoto Virtual Time-Space,’ in which we can virtually travel over space and time in the Japanese historical city of Kyoto. ‘Kyoto Virtual Time Space’ is an infrastructure to place various digitally archived materials associated with the city, and to disseminate Kyoto’s subtle and sophisticated forms of cultural and artistic expressions to the world over the internet. For this purpose, a database of elements that comprise urban landscapes in Kyoto is created; their locations are identified on a 2D-GIS; 3D-VR technique is employed to visualize the urban landscapes; and finally the above 3D-GIS is created for several time slices to form the 4D-GIS. The ‘Kyoto Virtual Time Space’ will be made public as a WebGIS on the internet.

The purpose of our research is to restore the whole city of historical city, Kyoto, in a virtual reality space. Our goal is to construct Kyoto Virtual Time Space in which we can walk through the streets of Kyoto from the olden days to the present and to the future on a computer display. The project involves 3D modelling of the present day Kyoto, and then restoring the city back to the pre-war period and to the mid-Edo era. Highly efficient GIS and VR technology are used throughout the project; (a) to store location and attributes of current buildings including Machiya, shrines and temples; (b) to archive and geo-reference any materials including Yamahoko at the Gion festival, as well as cadastral maps, street photos and aerial photos; and (c) to estimate and simulate landscape changes overthe oeriods using aforementioned materials.

We developed three different types of predictive distribution models for the presence/absence of Fagus crenata forests with four climatic parameters, and compared their performance. Generalised Linear Models (GLMs), Generalised Additive Models (GAMs), and Tree-Based Models (TMs) were compared in this way, due to their popularity in predicting plant species distributions. Four climatic factors; the minimum temperature of the coldest month (TMC), the warmth index (WI), winter precipitation (PRW), and summer precipitation (PRS); were used as explanatory variables in the model development. For GLMs, two sets of explanatory variables were applied, one of which was based solely on the four climatic terms (GLM-Simple), while the other included two-level interaction terms and quadratic polynomial terms (GLM-Complex). The models' performance was compared with AIC (Akaike's information criterion), residual deviance, and accuracy measures, including Kohen's kappa statistic and overall prediction success, which are often used in predictive modelling studies. The resulting values all indicated that TMs performed best, followed by GAMs, GLM-Complex, and GLM-Simple. We envisaged that the superiority of the TMs may be due to their binary recursive partitioning nature, which appears to give them a high capacity to capture the non-homogeneous Japanese climatic patterns nationwide. The model can explain the relationships between F. crenata forest distribution and climate factors well, although the forests are widely distributed under non-homogeneous climatic systems in Japan. We therefore support the use of TMs in predicting the presence/absence distributions of widely distributed forest types or plant species under the Japanese climate systems.

Nowadays many of the urban areas in Asian countries give more priority to economic development than to environmental issues. Information showing developing stages of urban area are generally restricted to published statistics by governments. Thus it is difficult to collect cross-sectional urban environmental indicators under a common criteria. DMSP (Defensive Meteorological Satellite Program)/OLS (Operational Linescan System) Stable Light Image (SLI) shows frequencies of light observation on the earth during nighttime. This study proposes a method to estimate spatial distribution of economic activity using SLI defined as an accessible indicator of light observation. From the enormous archives in NOAA National Geophysical Data Center (NGDC), the authors established temporal data sets in Asian region for 1992-3, 1996, 1998 and figured out impacts of -Asian economic crisis (1997) -stress in the marginal zone between India and Pakistan -temporal variability of fisheries in the Japan Sea (the Eastern Sea) through the analyses on these data sets. They also compared these data sets summed up in each province in China with some published statistics on socio-economic factors. Intensity of the nocturnal light showed high alterability for GDP and consumption of electricity (per km²).

This paper is a brief review of analytical medical geography, a subfield of medical geography using empirical-scientific approaches. Spatial analysis plays an important role in this field, to derive or confirm a series of logic of phenomena studied in aspects of geographic distributions. Here the three kinds of spatial analysis in disease and health research are focused on : 1) analyses of spatial clusters of incidents, 2) identification of spatial distributions of mortality and its association with urban ecology, and 3) spatio-temporal models of infections diseases. Approaches in these analyses vary from inductive to deductive and from confirmatory to exploratory : there are often conflicts between such pairs of research attitudes. Due to the development of new geographical information environment, many researchers who apply spatial analysis recently weight inductive and exploratory approaches. I summarize the potential problems of such approaches and the relations of various attitudes for analyses in recent medical geography.

Analysis of data aggregated in areal units is a general way to investigate collective social and ecolo-gical phenomena. The results of such analysis, however, depend on the adopted scale and configura-tion of areal units. This spatial aggregation problem is called MAUP (Modifiable Areal Unit Prob-lem). Several researchers (Broadbent, 1970; Openshaw, 1977; Masser and Brown, 1978; Putman and Chung, 1989; Batty and Sikdar, 1982a, b, c, d, 1984; Fotheringham, 1983a, b; Amrhein and Flowerdew, 1989, 1992) have examined spatial system design and its effects on spatial interaction models. The main questions have focused on the definition problem: how to make up areal units. Little attention, however, has been paid to the measurement problem, of which the most serious one in spatial analy-sis is defining the distance between areal units (Beardwood and Kirby, 1975; Rodriguez-Bachiller, 1983; Slater, 1985). This paper is concerned with relations between aggregate distance and biases of the distance-decay-parameter in the Huff model, which is typical of spatial interaction models. For the sake of simplicity the type of distance-decay-function of the Huff model is limited to the power function. Beardwood and Kirby (1975) showed how to define aggregate distance to predict, by spatial interaction models, consistently through spatial unit aggregation. The author terms the aggregate distance they pro-posed, non-bias distance (NB). Although "this is an accounting device of administrative rather than analytical or applied value" (Openshaw, 1977, p. 170), the author utilizes the idea of NB to compare with other conventional types of aggregate distance. Two types of aggregate distance are examined 1) simple mean distance (MD) of all the combinations for origin-and destination-BSUs (basic spa-tial units); and 2) mean trip distance (MT), defined as mean distance weighted with trip size. To begin with, theoretical investigations are performed in the following steps: 1) postulate trip pat-terns described perfectly by the Huff model at the BSU level; 2) aggregate BSUs to make up ASUs (ag-gregate spatial units) and define the utility of each ASU based on size and distance; 3) predict ratio of probabilities to choose an ASU nearer the origin and one farther from it, using the ASU data and the same parameter values as those at the BSU level; 4) consider whether such predictions lead to over-estimation or underestimation for the nearer ASU, by use of the NB idea; 5) if underestimation arises, say that the value of distance-decay-parameter estimated at the ASU level would be increased more (be steeper) than that at the BSU level because of the need to increase the probability by choos-?ing the nearer ASU rather than the farther one; in the reverse case, decreased (less steep) value would be estimated at the ASU level. The theoretical expected directions of aggregate biases of dis-tance-decay-parameters are shown in Table 2. Under the assumption of homogeneity of origin-BSUs' balancing factor in ASUs, the same expectations could be derived for the case where origin BSUs and destination BSUs are aggregated simultaneously. These findings were verified by sensitivity analysis of spatial aggregation effects like the previous studies (Openshaw, 1977; Putman and Chung, 1989; Amrhein and Flowerdew, 1989, 1992). The data for the analysis are shopping and private-purpose trips in the 23 wards of Tokyo City that consist of 115 BSUs. These data were collected through a 1988 Tokyo metropolitan area person-trip survey. Two experiments were undertaken. First the author examined the scaling effects at the scales of 23, 46, 69, and 92 ASUs by one hundred types of zoning randomly generated, respectively, and the zoning effects by two zoning procedures: random zoning (Openshaw, 1977) and nearest-neighbor zoning constrained by the criterion of zone compactness.

Multi-layered perceptron, a kind of neural network, is suitable for modeling complex phenomena in a noisy and restricted data environment. In spatial interaction modeling, Openshaw (1993) and Fisher and Gopal (1994) verified better performance of perception than classical models. Openshaw wrote “If the dependent variable is binomial or Poisson then the net will deduce this from the training data, there is no need to be explict”. However, both residual patterns of perceptrons and a log-linear gravity model were similar in the results of Fisher and Gopal (1994). They performed log-transform for output data, and trained networks by the least square criterion, which is normal for most perceptrons. If we regard each output of perceptrons as probabilistic expectation, then both of their trained perceptrons and log-linear gravity models would be assumed as log-normal distributions for error term. The similarity of residual patterns (under-prediction in large flows) could be caused by the same assumption of error distribution. To overcome such well-known features of log-normal models, we might use the Poisson regression technique (Flowerdew and Aitkin, 1982). In this paper, I specified PR-perceptron, which is a special type of two-layered perceptrons (Fig. 1). Its features are as follows. 1) By sigmoid hidden-units, PR-perceptrons can approximate any continuous mapping. 2) An exponential output-unit produces a positive real number with no upper limits, and 3) it also brings formal similarities between PR-perceptron and Poisson regression models. 4) Its training criteria is the maximum likelihood in the Poisson distribution. The PR-perceptron shares not simply the estimation process of parameters but also theories of undergoing process of spatial interaction with the Poisson regression, the family of maximum-entropy models, and discrete choice models, e. g. the multinominal logit model. I applied the PR-perceptron to 1990 inter-prefectural migration data for Japan and compared results with those of Poisson regression models (un-constrained, singly-constrained, and doubly-constrained models). The following results were obtained: 1) the PR-perceptron, which is non-constrained, showed the same level of goodness-of-fit as singly-constrained Poisson regression models (Tables 1 and 2). We recognized the superiority of the PR-perceptron even if we consider the trade-off relation between the number of parameters and generality of training results. 2) There were similarities in residual distribution between the PR-perceptron and Poisson regression model (un-constrained type) (Fig. 5) and no observed underprediction in large flows as log-linear models. This could indicate that the assumption of error distribution affects outcomes of the perceptrons. 3) Visualization of contents of trained PR-perceptron was carried out (Figs. 6 and 7). It enables us to a) verify assumptions about forms of utility functions, e. g. distance-decay function, and b) investigate exploratory non-linear relations and interdependency among variables. In this case study, we recognized intermediate distance-decay effects between power and exponential function, and non-monotonic non-linear relations according to characteristics of origins and destinations.

A mathematical model is built for influenza or other similar disease epidemics in a multi-region setting. The model is an extended type of chain-binomial model applied to a large population (Cliff et al., 1981), taking into account interregional infection by interregional contacts of people. If the magnitude of the contact is presented by simple distance-decay spatial interaction or the most primitive gravity model, a conventional gravity-type epidemic model (Murray and Cliff, 1977; Thomas, 1988) is deduced. Given the number of infectives and susceptibles, the chain-binomial model predicts the number of infectives in the next period with binomial probability distribution. Available data are, however, weekly cases per reporting clinic in each prefecture reported by the surveillance project, characterized by continuous variation; the data could be a surrogate index for rates of infection. The author modified the model to use rates of infectives and susceptibles, and used a normal approximation of binomial distribution. With the maximum-likelihood method, this model can be calibrated. The specification of the model is as follows: L_i(Y_{i, t=0}, …, Y_{i, t=T}|β°_i, δ_i)=Π_t1/√2πVar[Y_{i, t+1}]·exp{-1/2Var[Y_{i, t+1}](Y_{i, t+1}-E[Y_{i, t+1}])}, E[Y_{i, t+1}]=β°_i/M_iX_{i, t}Σ_jm_ijY_{j, t}, Var[Y_{i, t+1}]=β°_i/M_iX_{i, t}Σ_jm_ijY_{j, t}(1-β°_i/M_iΣ_jm_ijY_{j, t}), X_{i, t}=δ_i-Σⁱ_s=0Y_{i, s}, where M_i=Σ_jm_ij; L_i denotes the likelihood of the model for region i; X_{i, t} denotes the estimated rate of susceptibles in region i at week t; Y_{i, t} denotes the reported rate of infectives in region i at time t; m_ij denotes the size of interregional contact with the people in regions j for the people in region i; β°_i denotes the infection parameter in region i; δ_i denotes the parameter concerned with the rate of initial susceptibles in region i. The model posits that the average number of people who come into contact with a susceptible in prefecture i is a constant, and that the average rate of infectives of the people is Σ_jm_ijY_{j, t}/M_i. The probability of a susceptible in region i infected at time t is, therefore, β°_iΣ_jm_ijY_{j, t}/M_i. This model was applied to a weekly incidence of influenza in each prefecture, from the 41st week, 1988, to the 15th week, 1989, Japan, letting the size of interregional passenger flow T_ij correspond to m_ij as follows: m_ij=T_ij+T_ji (i≠j), m_ii=T_ii. Goodness-of-fits (Table 1) of one-week-ahead forecasts were almost satisfactory except for prefectures whose epidemic curves were bi-modal (e.g., Hokkaido) or whose transition speed between epidemic breakout and peak was too high (e.g., Yamagata). The latter might be explained by a cluster of group infection (e.g., school classes) in an earlier phase of the epidemic (see Fig. 4).

The aim of this paper is to clarify and model the geographical aspects of the HIV epidemic in Japan to examine the present and future states of geographical distribution of HIV cases and spatial relationships in HIV transmission. Although Japan has one of the lowest rates of HIV/AIDS cases among industrialized nations, the number of HIV/AIDS cases in the country has been steadily and rapidly rising. In the earlier phase of the HIV/AIDS epidemic (until around 1990), most of cases were reported from Tokyo and its surrounding prefectures. However, spatial diffusion of the epidemic is becoming apparent as the epidemic develops. We should now take note of the rising risk of HIV/AIDS in entire Japan. In this situation, the information concerning local epidemic states are necessary for supporting national and local health agencies planning preventive actions against HIV/AIDS expansion in Japan. We analyse the processes of HIV spatial diffusion based on the national HIV/AIDS surveillance, which began in 1984 but was legalized in 1989, with the aid of GIS mapping and spatial modelling.

To elucidate associations of socioeconomic residential segregation with health inequalities at the neighbourhood level, we examined the relationship between changes in the neighbourhood environment and changes in self-rated health and health behaviours before and after residential relocations by using a quasi-longitudinal survey in the Tokyo metropolitan area. As a result, residential relocation to more deprived areas were statistically associated with worsen self-rated health, less frequent exercise, more drinking, and more smoking. The result highlights the importance of neighbourhood effects as well as selective residential relocations in contributing to creating geographic health inequalities at the neighbourhood scale in the metropolitan area.
Changes in spatial structure of urban areas in depopulating society

Proceedings of the General Meeting of the Association of Japanese Geographers　2020

More details Close

Most of the urban areas in Japan is experiencing population decline. In this study, using demography and land use data, 109 Urban Employment Areas were classified into 6 groups in terms of in their urban spatial structure changes. As a result, in many urban areas, despite the population has relatively concentrated in the central areas, built-up areas continue to expand in the suburbs. This study also quantified the problems that emerged in a population-declining society, such as urban sprawl and decreasing urban density. The result showed that such "mismatch" in the spatial structure has a negative impact on efficient administrative services.

I はじめに 人口減少時代を迎えた日本における持続可能で体系的な地方創生のための計画手法の1つとして、GISを活用したジオデザイン（スタイニッツ、2014）を提案する。ジオデザインとは、地域の記述や説明に重点をおく地理学と地域の将来計画を得意とする計画学とを融合し、GISとICTを最大限に活用して、地域住民と専門家の協働によって将来計画を立案するために提案されたフレームワークである。本研究は、人口減少・高齢化が進行する典型的な地方自治体の１つである京都府与謝野町を対象に、ジオデザインの方法論と先端的な情報プラットフォームの適用を試みた2日間のワークショップ（2016年11月23・24日、立命館大学朱雀キャンパス）の成果内容を報告するものである。 II ジオデザインのフレームワークと対象地域 ジオデザインは、基本的に図1に示す6つの問いかけの繰り返しに基づいて構成される。 与謝野町は、平成の大合併の2006年に、旧岩滝町、旧野田川町、旧加悦町の3町が合併してできた町である（図2）。大江山連峰をはじめとする山並みに抱かれ、野田川流域には肥沃な平野が広がり、天橋立を望む阿蘇海へと続く総面積108平方キロメートルの範囲に約2万4千人が暮らしており、南北約20キロメートルの間に集落が連なっている（与謝野町HPより）。与謝野町は丹後ちりめんで知られる絹織物の生産地としても知られるが、高度成長期以降、繊維産業は衰退し、人口流出による人口減少が続いている。 Ⅲ ワークショップの内容 ワークショップは、参加者がWebを介してジオデザインに参加できる情報プラットフォームGeodesign Hub（https://www.geodesignhub.com/）を用いて進行した。本ワークショップの目的は、2010年（人口2万3千人、世帯数9千人、高齢者比率30%）の与謝野町をベースとして、30年後にあたる2040年の将来計画（推計人口1万5千人、世帯数6千人、高齢者比率42%）を策定することにある。まず、将来計画のベースとして、住宅、商業地、工場、農地、公共施設、グリーン・インフラ、ツーリズム、ランドスケープといった9つの視点を設け、対象地域を（Feasible、Suitable、Capable、Not Appropriate、Existing）の5段階にランクづけする評価マップをGISの空間分析機能を利用し作成した（10mメッシュの空間的解像度を採用）。将来計画では、新たな住宅、商業地、工場、農地、公共施設、グリーン・インフラ、ツーリズム、ランドスケープに関係する土地利用・施設の配置・規制を計画した。その際、合併前の3つの旧町のコミュニティを代表する3つの計画チームと、環境保全、経済、社会の視点から合併後の与謝野町全体の将来を考える3つの計画チームのそれぞれが将来計画案を提示した。最後の意思決定モデルの段階では、それら6つの将来計画案を与謝野町の利害関係者を含めた討論を経て比較し、最終的に1つの将来計画へと統合した。 参考文献 カール・スタイニッツ著、石川幹子・矢野桂司編訳（2014）：『ジオデザインのフレームワーク：デザインで環境を変革する』古今書院、226頁。 付記本研究は、立命館大学の2016年度国際化情報発信および歴史都市防災研究所の研究高度化予算の助成を受けた。

 1.研究の背景 2014年に東京都の代々木公園を中心としたデング熱の流行発生（70年ぶりの国内感染による流行）が示すように，日本における蚊感染性感染症の対策は喫緊の課題となっている．しかし，日本においてデング熱の流行リスクがどのように分布し，気候変動の影響によりそれがどのように変化していくかについては良く分かっていない．本研究では蚊媒介性疾患の理論疫学モデルに基づいた流行リスク指標を用いて，気温分布に基づく日本全土のデング熱流行リスク分布および気候変動予測に基づく将来の流行リスク分布を推定した． 2. 分析手法  気温の分布データは，1981～2010年の気候平年値および2031～50年の将来予測データ（地球温暖化予測情報 格子点値気象庁）と2014年を含む近年の気象観測値 (アメダス 気象庁)を用いた． デング熱の流行リスク指標としてロスマクドナルドモデル に基づいたrVcを計算した．    a: 吸血の頻度 b_m: 1回の吸血による人間から蚊への感染確率 b_h: 1回の吸血による蚊から人間への感染確率 n:  外潜伏期間（蚊の潜伏期間），μ_m: 蚊の死亡率 rVcは感染した蚊が人間の間に感染症を広める能力を示す指標であり,この値が高いほどデング熱の流行ポテンシャルが上昇し，0.2を超えると流行発生への注意が必要とされる. 蚊と人間の人口比の影響を調整した指標であり（すなわち，蚊の個体群密度そのものは評価しない），気候値からみたリスク分布推定の基礎として利用される．モデル中のパラメターはそれぞれ媒介蚊の種類および気温に依存する。日本におけるデング熱媒介蚊は、ヒトスジシマカと想定されており、気温を変数とするパラメターの具体的な数値はCheng et al.(2016)において整理された既往研究の成果を参照した．気温データとして前述のデータを投入し，それぞれrVcがどのように分布・時系列推移しているのかを算出し，GISを用いてリスクマップを作成した． 3. 分析結果  代々木公園近辺のアメダス観測所によって取得された2014年度の気温データに基づくヒトスジシマカのrVcの日別推移をみると，流行発生期間（8月から9月）はrVcが0.2を超える期間とほぼ一致することが分かる（図1）   また，2010年の気温分布の推定値データおよび将来推計データを用いてデング熱の流行リスクマップを描くことで，現在と将来の流行リスク分布を定量的に評価した（図2に将来のリスク分布図を示す）． 4. 考察  2014年の流行発生の事実と照らすことにより研究手法の妥当性について確認した上で，日本のデング熱流行リスクの空間分布と気候変動の影響を定量的に明らかにした．

Ⅰ．研究背景 近年では、都市化や温暖化による媒介蚊の生息域の拡大や、航空機・船舶等の輸送機器発達よって蚊媒介性感染症の新たな拡大が懸念されている(Tatem et al. 2006)。この感染症を媒介する蚊の分布域や個体数は、蚊の生態に関わる土地利用・土地被覆から構成される景観によって主に規定される(Trawinski and Mackay 2010)。そこで、米島ほか(2015)では、実際に観測された媒介蚊の個体数と土地被覆との関係から、吸血飛来する日本脳炎およびマラリア媒介蚊の潜在的な個体数分布をそれぞれ推定した生息ポテンシャルマップを、GIS環境を用いて作成した。本研究では、この2種類の媒介蚊の生息ポテンシャルマップの妥当性を、別年次に実施した新たな媒介蚊の捕集調査の資料を用いて検証した。 Ⅱ．方法 本研究では、日本脳炎媒介蚊であるコガタアカイエカおよびマラリア媒介蚊であるシナハマダラカ群を対象とした。対象地域は、滋賀県琵琶湖東沿岸地域にあたる彦根市、東近江市の旧能登川町地区、旧安土町を含む近江八幡市である。生息ポテンシャルマップの作成にあたっては、湖沼、河川など多様な水域の周囲20地点において2009年5月から10月にかけて実施した、成虫蚊の捕集調査資料を利用した。土地被覆のデータは、衛星画像（ALOS、2009年5月18日撮影）から画像分類し、各調査定点周囲、半径50mから3kmまでの土地被覆の面積構成比を利用した。そして、観測された捕集個体数と土地被覆との関係性を、偏相関最小二乗法(PLS)回帰分析を用いて実施した。分析によって、最も適合度の高い半径のPLS回帰モデルを採択し、GIS環境において2種類の媒介蚊の生息ポテンシャルマップを作成した。さらに、2010年6月から10月にかけて16ヵ所で実施した成虫蚊の捕集調査資料を用いて、作成した生息ポテンシャルマップの妥当性を検証した。 Ⅲ．結果・考察 PLS回帰分析の結果、コガタアカイエカの個体数変動は半径900mの土地被覆によって約64%が説明され、シナハマダラカ群の個体数変動は半径100mの土地被覆によって約49％が説明できた。これらの最適モデルを用いて作成した生息ポテンシャルマップによって、コガタアカイエカは水田が広がる平野部に、シナハマダラカ群はヨシが生育するような水域や湿地帯周辺に、生息個体数が多いことが示された。 作成した生息ポテンシャルマップの妥当性を検証するために、ポテンシャルマップから抽出した蚊の生息個体数の推定値と、2010年に実施した蚊の調査定点の観測値について相関関係を分析した。その結果、シナハマダラカの生息ポテンシャルマップは比較的高い精度で予測されており、妥当性が高いことが確認された(r = 0.55、p = 0.03)。一方、コガタアカイエカの生息ポテンシャルマップと検証に利用した観測値との相関関係は低く (r = 0.30、p= 0.27)、とりわけ西の湖周辺および河川の近接する調査地点の精度が低いことが確認された。対象地域では、季節特有の風があり(豊田1991)、水域周辺では障害物がなく、風の影響を受けやすいため、推定値と観測値の差が大きくなった可能性がある。また、土地被覆の年次変化の反映や、土地被覆分類での水域の区分を、蚊の発生条件を考慮して再検討するなど、生息ポテンシャルマップの精度向上に関するさらなる検討が必要と考えられた。

Ⅰ．研究の背景と目的阪神淡路大震災から20年、東日本大震災から4年の歳月が流れた。将来起こりうる災害に対応するさまざまな対応策が求められている今日、防災・減災に向けた地理情報の活用が盛んに議論されている。そのなかで、地域の記憶を共有する媒体となる文化財の価値に着目し、災害発生時における文化財の脆弱性や文化財の消失・損傷のリスクを評価する研究が蓄積されつつある（中谷 2014）。このような機運に鑑みて、本研究では南海トラフを震源とした地震が引き起こしうる被害――とくに津波による文化財の被災に着目する。東日本大震災における文化財の被害は、地震の被害と比較すると、浸水域が狭い範囲に限定されるものの、全損・流失などの壊滅的な被害に遭うことが報告されている。そこで、本研究では近い将来に発生する可能性が高く、多大な被害をもたらすと予想されている南海トラフ地震発生時の津波による文化財被災リスクの評価を行ない、文化財防災の視点からみたハザードマップの可能性を検討する。 Ⅱ．研究資料対象とする国指定登録文化財の地理情報は、文化庁がweb上で公開している「国指定文化財等データベース」（2015年2月時点；日本全国1,7937件）より作成した。このデータベースには各々の文化財の位置を表す緯度経度座標が付与されている。なお、本研究における対象文化財は、国指定登録文化財のなかでも地域における歴史的文化的価値に着目して、（1）国宝・重要文化財（建造物）、（2）登録有形文化財（建造物）、（3）無形民俗文化財、（4）記念物（史跡・名勝・天然記念物）、（5）重要文化的景観、（6）重要伝統的建造物群保存地区とした。また、南海トラフ地震にともなう津波浸水深については、内閣府の南海トラフ巨大地震モデル検討会において検討された震度分布・浸水域等に係るデータの浸水メッシュデータを利用した。 Ⅲ．文化財被災リスクの評価本研究で利用する浸水メッシュデータはさまざまな状況（ケース）別に作成されているため、それぞれのケースを対象に浸水深データと文化財レイヤを重ね合わせた検討が必要である。一例として、付表に文化財の種別と想定浸水深（m）のクロス表を示す。南海トラフ地震によって主として被害を受ける西日本地域では、沿岸部に国宝・重要文化財（建造物）の立地も散見されるものの、登録有形文化財（建造物）の被害予想が突出していることが分かる。これは東日本大震災の経験とも一致する（豊田ほか 2011）。登録有形文化財（建造物）には近代建築物が多く含まれ、そられは過去の津波被災後の市街化の過程で築かれてきたと考えられる。文化財の被災予想を集計・地図化するとともに、文化財被災の地理的背景について検討する。

I．研究背景と目的  東日本大震災の経験から、甚大な災害時にも利用可能な情報入手手段としてワンセグ放送の価値が改めて指摘されるようになった（総務省2013）。これを受けて、本研究の対象である立命館大学衣笠キャンパスにおいては、ホワイトスペースを活用したエリア限定ワンセグ放送による防災情報共有システムの構築を進めている。このシステムの主な利用者となる学生に有用なメディアデザインとコンテンツデザインの確定には、災害に対する学生の意識や災害発生時の学生の行動を理解しておくことが不可欠である。   これまでにも大学生を対象とした防災意識に関する調査報告が蓄積されてきた（後藤ほか2004；黒崎ほか2007など）。そこでは、大学生の防災意識の低さや知識の欠如とともに、大学での防災訓練・防災教育の必要性が指摘されている。また、開講期間中に発災した場合、大学には多数の学生がキャンパスに滞在していることから、多くの帰宅困難者ならびに混乱が発生することが予想される（森田ほか2014）。そのため、事前の帰宅困難者の推計も必要とされている。そこで、本研究では大学生を対象とした質問紙調査によって防災意識と帰宅行動に関する意向を把握し、さらには、それらを規定する各種の要因を検討する。   II．調査の概要と分析方法  調査票は、①個人属性（通学経路や滞在時間等）と情報入手手段の所有実態、②防災・災害に関する経験、③災害の備え・知識、④災害時の対応、⑤メディアの利用経験、⑥キャンパス内の行動の6セクションから構成されるように設計した。なお、京都市防災マップを参考に、設問は地震災害に限定して災害に対する設問を設定した。衣笠キャンパスに所属する学部生・院生を対象とし、各学部および大学院生の在籍数を基準に600人の調査票回収を設計した。調査への協力者は、2014年12月3～5日にキャンパス内の屋外にて募った。ここでは、特に①～④の設問のうち災害への備えおよび災害時の行動に着目し、その規定要因を回答者の経験や居住環境といった個人属性から統計分析した。   III．分析結果と考察  調査では、災害に備えることについてどう思うかを、興味、必要性、責任、信頼、知識・情報、自主性、他者との関係性、イメージのそれぞれの項目について5段階評価を求めた。その結果、「かっこいい」、「明るい」といったようにポジティブに捉えている回答者ほど、災害時の備えをしており、災害ボランティアなどの経験があることがわかった。すなわち、備えに対するイメージの好感度を上げることによって、災害の備えを高めることができるものと考えられる。  大学滞在中に地震災害によって帰宅困難になった場合、大学に留まるか否かの行動選択には、大学から自宅までの距離および性別との関係性が認められた。大学と自宅までの距離が10km以内の学生は、徒歩で帰ることができると判断する傾向がみられたが、なかでも一人暮らしをしている学生は大学に留まることを選択することも多い。これは、下宿先の滞在よりも大学の滞在の方が安全であることを想定してのものと思われた。  なお、帰宅困難時には、大学から自宅まで20km以内の場合、徒歩での帰宅を推奨しているが、災害時に正しい判断や行動ができる自信が「まったくない」、「ない」と回答した学生は381人（63.6%）にのぼる。これを踏まえれば、発災時には情報や人の行動の混乱が生じ、帰宅困難者が想定よりも増加することが考えられる。  以上の結果から、平時から学生への災害・防災の情報提供を行い、発災時の対応力を養うことが必要である。その方法として、記憶定着率が高いとされる映像を利用し、災害への備えに対するイメージ好感度が上がるようなコンテンツの提供が有効になるものと考えられる。  引用文献 黒崎ひろみ・中野晋・小川宏樹・岡部健士・村上仁士2007. 2006年度工学部新入生を対象とした防災教育の実施と防災意識調査. 大学教育研究ジャーナル4: 15-21. 後藤裕美・石川孝重・伊村則子2004. 都心キャンパスに通う大学生の地震災害に対する認識と行動に関する研究―その1 アンケート調査の概要と地震災害に関する知識―. 日本建築学会大会学術講演学術梗概集:441-442. 総務省2013.「平成23年度版情報通信白書」. http://www.soumu.go.jp/johotsusintokei/whitepaper/ja/h23/pdf/n0010000.pdf 森田匡俊・正木和明・奥貫圭一・落合鋭充・小林広幸・倉橋奨 2013. 愛知工業大学八草キャンパスにおける大規模災害発生時の帰宅困難者数の推計. 平成24年度愛知工業大学地域防災研究センター年次報告書9:57-64.

１．背景と目的 健康的な生活を支える食料品へのアクセスが剥奪される地域的状況はフードデザートと呼ばれ、特定の社会集団の健康水準を低下させる要因として指摘されてきた。日本社会では、中心商業地の衰退に伴う店舗の閉鎖や都市的な環境で広がる社会的疎外が、高齢者を中心とする徒歩によって生鮮食料品を購買していた居住者に深刻な影響をもたらすと危惧されている（岩間, 2011）。2011年３月に発生した東日本大震災では、津波被災地区を中心に発生した被災による食料品購買機会の喪失が問題となっている（岩間ほか, 2012）。 フードアクセスをめぐる課題を受け、近年では生鮮食料品を販売する店舗へのアクセスを評価する地図成果物が公開されるようになった。例えば、農林水産研究所が公開している食料品アクセスマップでは、500mと定義された徒歩圏内にスーパー等の食料品購買機会を得られない地区が示されている（薬師寺・高橋, 2012）。ただし、徒歩圏内に購買機会のない環境が長期的に維持されている場合には、その環境に適応した食料品の確保（例えば、自動車による購買行動）がなされているとも考えられる。そのため、本研究では徒歩での購買行動が可能であった地区において購買機会が失われた状況が、フードアクセスの問題を最も深刻に被る地区と想定した。 また、フードデザート問題は、欧米社会にみられる大都市部の貧困地区の健康問題から提起されてきた論点ではあるが（中谷, 2010）、こうした問題発生地区の社会的位置付けを、日本全体を対象として俯瞰する試みはなされてこなかった。これを踏まえて、本研究では近年の生鮮食料品販売店舗の閉鎖に伴って生じた、徒歩でのフードアクセスの喪失地区を特定し、当該地区を社会地区類型（ジオデモグラフィクス）を利用して評価することを試みる（中谷・矢野, 2014）。対象期間は、震災発生前の2010年からその3年後の2013年とした。 ２．資料と方法 (1) 座標付き電話帳データベースであるテレポイントPack!（全国版）の2011年2月（2010年10月発行の電話帳と対応）と2014年2月版（2013年10月発行の電話帳と対応）を用いて、生鮮食料品購入可能店舗の抽出を行った。業種はスーパー（生協等店舗を含む）、その他の食料品店（コンビニ、個人商店等）に区別し、店舗名等から実質的な小売店舗であるものに限定した。 (2) GIS環境において直線距離500m圏を徒歩圏として、時期別に徒歩圏での食料品アクセス可能範囲を特定するレイヤを生成した。また、両レイヤのオーバーレイによって、食料品店舗への徒歩アクセスの変化を識別した。さらに、各圏域に含まれる人口を基本単位区の人口統計（2010年）を平滑化して推計した。 (3) 食料品アクセスの衰退地区に居住する人口を、町丁字等単位の社会地区類型別に比較した。社会地区類型にはMosaic Japan 2010年版（エクスペリアンジャパン（株））を利用した。 ３．徒歩フードアクセスの喪失マップと地区類型 徒歩によるフードアクセスが近年失われた地区の全国分布図を作成し、当該地区の地域別・社会地区類型別の特徴を、業種別に検討した。抽出された食料品購入可能店舗の総数は減少しており、とくに津波被災地区ではスーパー以外の店舗の減少が著しい。 地区類型別の整理の一例として下図に、2010年において徒歩圏内にスーパーのある地区に居住していた人口の内、2013年にスーパーへの徒歩アクセスを失った割合（％）を、Mosaic Group別に示す（人口密度が低いグループほど上に配置してある）。徒歩によるフードアクセスの喪失は、地区の社会的属性に応じても特徴的に異なることがわかる。 本研究は，厚生労働科学研究費補助金循環器疾患・糖尿病等生活習慣病対策総合研究「日本人の食生活の内容を規定する社会経済的要因に関する実証的研究」（研究代表者：村山伸子）および科学研究補助金・基盤研究(B)「ＧＩＳベースの日本版センサス地理学の確立とその応用に関する研究」による成果の一部である．

1．研究の背景と目的 インフルエンザ流行を対象とした空間的伝播研究はこれまで数多く実施されてきた（Cliff et al., 1986）．日本国内においても，都市階層と人の接触頻度の空間的制約からシミュレーションを行った研究（杉浦, 1975）や空間的な理論疫学モデルを用いて感染者数の時空間的な推移を分析した研究（中谷, 1994; 片岡ほか, 2012）が見られる．しかし，先行研究の多くは演繹的なモデル分析研究であり，実際の流行実績から，流行伝播の空間的パターンを抽出する研究は少ない．永田・中谷（2013，2014）は空間データ解析の手法を用いて，2009-2010年シーズンにおける茨城県の公立小中学校の閉鎖措置データを分析し，流行伝播の空間的パターンが地域内外での人の接触頻度や地域間ネットワークの地域差と関係することを示唆した．本研究では，小中学校を単位とする詳細な空間的解像度をもって，人の接触頻度に関連する地域的指標や流行地区との接続性指標を変数とした流行伝播モデルの構築を目的とする． 2．方法 流行実績を示す資料としては『インフルエンザ患者の発生に伴う学級閉鎖等の措置について』（茨城県保健福祉部予防課・茨城県感染症情報センター）を用いた．この資料には2009-2010年シーズンの新型インフルエンザ流行による閉鎖措置を実施した学校名，患者数，閉鎖期間が記録されており，閉鎖措置を初めて実施した日を各学校の流行開始日とみなした．なお，分析対象期間は2学期開始の9月1日から2学期の最終日である12月24日までとした． 本研究では各学校について，流行が発生した場合に「1」，未発生なら「0」とする流行発生判定を1日ごとに行い，流行発生状況を被説明変数とする二項ロジスティック回帰分析を実施した．説明変数には，近隣学校の流行発生状況や流行地区との流動量を指標とする流行地区との関係性指標に加え，学校や学校区に関する指標を投入した．なお，流行期間中で初めての流行発生のみを対象として予測を行うため，流行が開始した学校は次の日以降のデータから除外される．学校区に関する指標に含まれる学校区の中心性指標は，学校立地密度と，PageRankアルゴリズムに基づいて学校区間の流動量から算出した中心性の値を変数とした．情報量規準に基づいたパラメータ推定を行い，最も優れたモデルを用いた乱数シミュレーションの結果と流行実績を比較した． 3．結果と考察 二項ロジスティック回帰分析の結果，地区の中心性指標としてPageRankによって算出された値，流行地区との関係性指標として流行地区との流動量を反映した値を投入したモデルが最も優れたモデルとして認められた．すなわち，近隣学校の流行発生状況よりも，地区間での人的な接続度合が流行に影響し，学校間というミクロなスケールにおいても，流動量を用いたモデリングが効果的であることが実証された． 情報量規準を最小にするモデルを用いて乱数シミュレーションを行ったところ，流行曲線や流行伝播の空間的パターンが実際の流行と異なる傾向となった．そこで，対象期間を流行初期，流行拡大期，流行蔓延期に分けて，再度パラメータを推定した結果，流行曲線と空間的パターンの両方で，実際の流行と類似した傾向を再現することができた．流行初期と流行拡大期において，学校のタイプや学校区の14歳以下人口割合が有意に関係しており，流行初期での流行伝播には，生徒同士のネットワークが強く関係していたと考えられた． 本研究は，RISTEX科学技術イノベーション政策のための科学「感染症対策における数理モデルを活用した政策形成プロセスの実現」（代表：西浦博）による成果の一部である．

1990年代以降の社会格差をめぐる関心の高まりの中、日本社会での所得格差の拡大とともに、健康の社会格差拡大への懸念も提起されるようになった。歴史的にみれば、英国の”Black Report”が世に出された1980年代以降、欧米では健康の社会格差は、社会階層間での健康の不平等の問題として、その存在が繰り返し確認され、その観察にはしばしば地理的な健康の不平等の存在も含まれていた。すなわち、所得のような社会経済的位置が集合的に低い地域には、死亡率等で測られる健康水準が目立って低くなる、といった観察である。こうした健康の不平等の指摘は、その是正を目標とする公衆衛生上の政策的対応を促し、2013年以降の第２次健康日本21においても、健康の社会格差・地域格差への対策が課題とされるようになった。では、日本社会ではどのような健康の地域格差が認められ、健康の社会格差とはどのような関係にあると考えるべきだろうか。本報告では、健康の地域格差を可視化・計測するこれまでの取り組みの成果をふまえて、日本社会での健康の地域格差と社会格差の関係をつなぐ地理学的な論点と課題を整理する。

Ⅰ．問題の所在 2011年3月に発生した東日本大震災から4年の歳月が経とうとしている。被災地域の復旧・復興のプロセスにおいては、まず災害に耐えうるまちづくりが課題とされ、講じられる復興策として、被災地域の建造環境の再構築が重要視されてきた。しかし、地域が培ってきた祭礼や文化活動の復興も同様に重要性を持っていることが、阪神淡路大震災の被災地域における研究で指摘されている（相澤2005）。そこでは祭礼に関わる住民の取り組みを取り結ぶ媒介として「記憶」が重要な役割をはたしてきた。 本研究では、東日本大震災による被災地域である宮城県南三陸町志津川地区を対象として、震災後において変化を迫られ、消滅の危機さえある地域で行われてきた祭礼や年中行事にまつわる「記憶」を抽出した。さらに、そこで得られた情報を記録した「記憶地図」が、地域文化の継承に配慮した復興まちづくりに貢献する可能性を検討した。 Ⅱ．調査概要・研究方法 対象地域において、古くから祭礼の運営や地域信仰の中心的な役割を担ってきた五つの神社（上山八幡宮・保呂羽神社・荒島神社・西宮神社・古峯神社）を取り上げ、それぞれの神社の関係者である禰宜・別当・世話人・氏子の計8名に対して聞取り調査を実施した。主な質問項目は、東日本大震災被災前の、①祭礼や年中行事の運営方法、祭礼における行列のルートの記憶、②祭礼とともにある場所・風景の「記憶」、③氏子の居住地区などコミュニティの広がり、④祭礼や神社と地域とのつながり、また、⑤震災後における祭礼の実態や神社と人々との関わりについてである。これら聞取り調査の結果得られた情報はGISを利用して地図上に記録し、祭礼にまつわる「記憶地図」を作成した。 また、聞取り調査における関係者の発話は音声データとして記録を行ない、それらは可能な限り文字データ化し、「記憶地図」と併せて利用した。なお、南三陸町における聞取り調査は、2014年8月26日から8月31日にかけて実施したものである。 Ⅲ．「記憶地図」が語るもの 志津川地区内の五つの神社は、五社会という組織を形成しており、上山八幡宮の宮司がすべての神社の宮司を兼任している。まずは、中心的な存在である上山八幡宮への聞取り調査の結果から作成した「記憶地図」（第1図）を検討した。秋の例大祭における稚児行列のルートをみると、この祭礼が子供の成長を地域社会にお披露目するという意味を持つことから、多数の氏子が居住する地区を取り囲むようなルートが、街をあげてさまざまな視点から調整されていた。例えば、志津川病院移転後には病室から稚児がみえるようにと、ルートを変更しており、地域社会の動向をふまえた柔軟性に富む運営が行われていた。また、上山八幡宮のルーツは保呂羽山と密接な関係があり、保呂羽山山頂、旧上山八幡神社の所在地と現上山八幡宮を結ぶ一直線のライン（祈りのライン）は由緒を確認する象徴的な景観上のしかけとなっている。 以上のように、「記憶地図」は今まであまり可視化されることのなかった、地域で行われてきた祭礼の実態や意味づけされた場所の視覚的把握を可能とする。復興計画では、居住地の移転が計画されているが、神社へのアクセスは考慮されておらず、上山八幡宮の禰宜は、地域文化を継承する計画上の仕組みの必要性を主張している。すなわち、復興という建造環境を再構築する中で、祭礼に関わる人々の取り組みを取り結び、意味づけされた場所を新たに創り出すための装置が求められている。「記憶地図」は、これまでの祭礼で取り結ばれていた人々の想いを住民が自らの手で確認し、まちづくりの方向性を考えるための一つのツールになり得ると考えられる。 参考文献   相澤亮太郎 2005. 阪神淡路大震災被災地における地蔵祭祀――場所の構築と記憶. 人文地理57-4: 62-75.  [付記] 本研究は、科学研究費・基盤研究C（25420659）「地域の文化遺産が被災後の復興に果たす役割に関する研究」（研究代表者：板谷直子）の助成を受けたものである。

国内最後のマラリア浸淫地として知られた滋賀県琵琶湖東岸地域において，現在の蚊の発生状況を把握するために，2008年からCDC型トラップを用いて蚊の捕獲調査を行っている．2010年は，琵琶湖に注ぐ犬上川流域を縦断的に，また内湖である西の湖周辺を対象として，地点間による蚊相と捕獲数の差異を明らかにするために調査を行った．方法は，ドライアイス1kgを誘引剤としたCDC型トラップを用いて，6月18日から10月2日まで，3週間毎に2日間連続で行った．調査地点は，犬上川の上流から下流にかけて12地点，西の湖沿岸およびそれに注ぐ蛇砂川流域に10地点を設定した．その結果，シナハマダラカ，コガタアカイエカ，アカイエカ，カラツイエカ，ヒトスジシマカ，ヤマトヤブカ，オオクロヤブカ，ハマダライエカ，フトシマツノフサカの10種類が捕獲された．犬上川流域では，全捕獲数21,233個体のうち約92％がコガタアカイエカ（19,585個体）で，次いでアカイエカが約7％（1457個体），シナハマダラカが0.2％（57個体）であった．トラップの設置地点間を比較すると，犬上川上流および下流ではコガタアカイエカの捕獲数が多いのに対し，中流部では少なかった．また，上流部ではアカイエカの割合が低かった．一方，西の湖周辺では総計40,347個体のうち、約97％がコガタアカイエカ（38,998個体），アカイエカが約2％（608個体）そしてシナハマダラカが約1％（462個体）捕獲された．地点間の比較では，コガタアカイエカは特に西の湖沿岸に多く，シナハマダラカは蛇砂川流域で多いことがわかった．このように地点間比較から，捕獲数および蚊相にはトラップ設置場所によって差異が認められる．この差異について，環境省生物多様性情報システムの第5回植生調査データを資料とし，GIS（地理情報システム）を用いて，トラップ周囲の植生構成比との関係から検討した．また，2009年度の調査データを基に作成した吸血飛来のポテンシャルマップと2010年度の蚊の調査結果がどの程度一致したのかを検証した．

I はじめに 現在，地域住民や地方自治体，日本政府による様々な取り組みにより，日本各地において歴史的景観の保全が図られている。これらの歴史的景観は所与の自然環境のもとで築き上げられた人間活動の所産であり，文化財に指定されている伝統的建造物や史跡のみならず，文化財に指定されていない建造物や民家建築，町割など，多様な景観要素によって構成されている。しかし，これら歴史的景観は，現在においても開発と保全との狭間に置かれ，しばしば利害関係者の間で紛争の対象となっている。これは，歴史的景観が公共財としての側面を持つと同時に景観を構成する要素の多くが私的財であり，歴史的景観の維持や改変が誰にとってどの様な価値を有するのかを明示しにくく，地方自治体や政府が支援する景観保全政策の推進に際しても，どの程度の財政支援を行うのが妥当かを示しにくいことに起因する。この問題を考えるべく，本研究では歴史的景観を保全することで生まれる効果を地域住民と観光客の視点の双方から社会経済的に評価することを目的とする。 II 分析資料 本研究では，歴史的建築物の保全や建築物のデザイン改修による歴史的景観保全に関する意識調査を実施した。具体的には，_丸1_京都市内在住者に対しては歴史的景観整備に関する支払意思額（WTP），_丸2_京都市外在住者に対しては歴史的景観が整備された場合に京都を訪問する仮想行動（CB）を質問し，歴史的景観保全の便益を2種類の評価測度で計測した変数を準備した。本調査では，20歳以上のYahoo!リサーチ登録モニターに対するインターネット調査を実施した。本調査では，2005年国勢調査における20歳以上人口の，性別，年齢階級，居住地域を考慮し，2007年2月8日時点のYahoo!リサーチ登録モニターから系統抽出法により3,945名（京都市内＝698名，京都市外の全国＝3,247名）の計画標本を抽出した。未達数が3通のため有効発信数は3,942通である（有効回答率＝48.5%）。アンケート調査は，2007年2月8日～13日にかけて実施した。 III 結果 本研究では，地理的な変数に着目して京都市内在住者によるWTPや京都市外在住者によるCBの分析を試みたが，それぞれの変数と地理的な変数との単純な2変量間の関係においては有意な関連性は確認できなかった。この点に関しては，WTP関数や訪問頻度関数の推定において，WTPやCBに与える被験者の居住地や社会経済属性の影響を同時に考慮した回帰分析に取り組む必要がある。また，訪問拒否に着目した分析からは，やむを得ない理由で訪問を拒否した理由には，金銭的な理由で訪問拒否した回答の割合が京都市からの距離に正比例しているのに対し，時間的制約を理由に訪問を拒否した回答の割合は京都市からの距離に反比例している傾向が確認された。このことは，京都市から遠くに居住する者は金銭的な問題が解消されたら訪問の意思を表明することを示しており，当該地域においては家計の消費を刺激する経済政策により潜在的な需要を見出せる。一方で，京都市に相対的に近くに居住する者は，時間的な問題が解消された場合の潜在的訪問者である。比較的近距離の観光需要の喚起には，長期連続休暇制度の確立や有休休暇の消化促進などに向けた政策立案が望まれよう。

I はじめに 近年，市場調査や医療・疫学研究の分野では，インターネット調査の利用が急速に普及し始めている。インターネット調査には経済性や迅速性の利点がある一方で，被験者の設定問題や回答収集方法に関わる問題が指摘されている。これらインターネット調査の持つ利点と欠点について，市場調査においてはしばしば経済性と迅速性といった利点が強調されてきた。しかし，母集団の代表性の問題に関心を持つべき社会調査においては，従来型のデータ収集方法と比較してインターネット調査にどの様な問題が存在するのかを考える必要がある。そこで本研究では，歴史的景観復興に対する意識調査データを題材に，社会調査データの収集方法（郵送調査とWeb調査）が景観に対する意識，とりわけ景観復興に対する支払意思額（WTP）に与える影響を，被験者の社会経済属性や居住地属性を考慮しつつ検討することを目的とする。 II 分析資料 (1)分析データ 本研究では，京都市における災害発生後の歴史的景観復興を想定し，歴史的景観の継承に関わる意識調査を，20歳以上の京都市内在住者に対してWeb調査および郵送調査で実施したデータを用いる。分析に利用するデータは (1)従属変数：歴史的景観復興に対するWTPを示すWTP，抵抗回答か否かを示すProtest，(2)データの収集方法を示すWeb，(3)被験者の社会経済的属性：性別を示すSex，年齢を示すAge，所得を示すIncome，(4)被験者の居住地属性：京都市内在住年数を示すYear，都心4区（上京，中京，下京，東山）に居住しているか否かを示すCitycentreである。 (2)調査の概要 本調査では，Web調査と郵送調査に基づき，京都市内に在住している個人に対してアンケート調査を実施した。Web調査では，Yahoo!リサーチの登録モニターを調査対象者とした。本研究における標本抽出では，性別，年齢階級を考慮した層化抽出法により698名を計画標本とし，有効配信数698（未達数0）に対して調査協力の依頼を行った。このうち，有効回答回収数は329（有効回答回収率＝47.1%）である。一方，郵送調査では，京都市に住民票を届出ている者を調査対象者とした。サンプリング台帳としては住民基本台帳を利用し，系統抽出法により1,500名を計画標本とした。転居等の事由により15通が未達であり，最終的には1,485通の有効配布数のうち，WTPおよび正常回答の判断に必要な質問に回答漏れの無かった536通を有効回答とした（有効回答回収率＝36.1%）。アンケート調査は，Web調査を2007年2月8～13日，郵送調査を2007年3月30～5月11日に実施した。 III 結果 (1) データ収集方法と抵抗回答率との関係 WTPを用いた分析では，しばしば有効回答から抵抗回答を除いた回答（正常）が用いられる。抵抗回答とは，歴史的景観復興に対する価値を認めてはいるが，シナリオに対する抵抗感から0円回答を選択した回答である。この抵抗回答は，シナリオを正確に把握していないという判断から，WTPの評価から除外される。つまり，抵抗回答率の違いを原因として，WTPに大きな変動が生まれる可能性がある。そこで，調査で得られた回答者の社会経済／居住地属性の違いを含めて，従属変数をProtestとする二項ロジスティック回帰分析を行なった。変数選択ではデータ収集方法を表すWeb，社会経済／居住地属性に関わる5変数，そしてこれら5変数とWebとの交互作用を考慮し，これらを掛け合わせた5変数を独立変数として投入した。そこでは，有意確率が0.050以上の変数の中から有意確率の高い変数から順番に削除していった。その結果，Webは有意な変数とはならず，AgeとIncomeがProtestに正の影響を与えていることが分かった。 (2)データ収集方法とWTPとの関連性 データ収集方法は抵抗回答率にとは統計的に有意な関連性が認められなかったため，以下の分析では329のWeb調査回答者のうち296の正常回答を，536の郵送調査回答者のうち465の正常回答を，それぞれ分析に利用することにした。そこで，回答者の社会経済／居住地属性の違いを含めて，WTPを従属変数とするグループデータ回帰モデルを検討した。変数選択の過程は，Protestの二項ロジスティック回帰分析と同様である。そこでは，有意確率が0.050以上の変数の中から有意確率の高い変数から順番に削除した。その結果，WTPに対してWebが負の影響を，Webと所得の交互作用項であるWeb×IncomeとWebと年齢の交互作用項であるWeb×Ageが正の影響を与えていることが分かった。つまり，(1)Web調査回答者のWTPに比較して郵送調査回答者のWTPが高いが，(2)Web調査回答者の方が所得や年齢によるWTPの違いが大きいことが分かった。また，都心4区居住者か否かを基準としたWTPの地域差が認められないことが明らかになった。

本研究は、『京都地籍図』とGISを用いて大正元年当時の京都の景観を１筆単位で復原することを試みる。『京都地籍図』は、上京区・下京区・接続町村の3部で構成され、それぞれ地籍図と付属の土地台帳（以下、付属台帳）にわかれている。地籍図には土地１筆ごとの地番・面積、一部には学校・寺社名などが、付属台帳には地番・面積・地価・等級・所有者住所・所有者名など、景観復原の際の重要な事項が記載されている。これらの土地１筆に関する様々な情報は、GISを用いることで一元的に管理できる。それによって当時の土地所有者、地価、等級を現在のデジタル地図情報と比較することも可能となる。さらに、『京都地籍図』を空間基盤データとし、地籍図以外の資料のデータを付加することで、様々な景観復原に活用できる。GIS化を行ったのは御池通・鴨川・四条通・堀川通に囲まれる範囲である。２次元デジタル地図と地籍図の重ね合わせには、画像データを元に１筆ごとの土地をポリゴン化し、「アジャスト」機能を利用して現在のデジタル地図に重ね合わせる方法を用いた。対応する属性データとしては、付属台帳に記載されている地番・地目・面積・地価・等級・所有者住所・所有者名を１筆ごとにデータ入力を行った。それにより、データ内容を地図上に反映することができる。以上の方法を用いて、『京都地籍図』と２次元デジタル地図を重ね合わせた結果、おおむね高い精度で現在の２次元デジタル地図との重ね合わせできた。付属台帳に記載されている等級を反映させると、当時の土地は新京極錦小路の124等級を頂点として南北に123等級、122等級の筆が広がる。また現在の京都の大きな繁華街である河原町通の等級は相対的に低いことが大正元年当時の景観復原により明らかとなった。さらに、この土地割りのデータを利用して大正元年当時の景観の３次元化を行い、多数の建築物からなる町並みの再現も行った。

Nowadays many of the urban areas in Asian countries give more priority to economic development than to environmental issues. Information showing developing stages of urban area are generally restricted to published statistics by governments. Thus it is difficult to collect cross-sectional urban environmental indicators under a common criteria. DMSP (Defensive Meteorological Satellite Program)/OLS (Operational Linescan System) Stable Light Image (SLI) shows frequencies of light observation on the earth during nighttime. This study proposes a method to estimate spatial distribution of economic activity using SLI defined as an accessible indicator of light observation. From the enormous archives in NOAA National Geophysical Data Center (NGDC), the authors established temporal data sets in Asian region for 1992-3, 1996, 1998 and figured out impacts of -Asian economic crisis (1997) -stress in the marginal zone between India and Pakistan -temporal variability of fisheries in the Japan Sea (the Eastern Sea) through the analyses on these data sets. They also compared these data sets summed up in each province in China with some published statistics on socio-economic factors. Intensity of the nocturnal light showed high alterability for GDP and consumption of electricity (per km²).

わが国では、がん罹患率、循環器疾患受療者が増えているが、死亡率が減少していることから、がん生存者、循環器疾患生存者が増加していることが予測される。しかし、がん生存者、循環器疾患生存者の、罹患後の予後を改善する生活習慣・食習慣については、いまだエビデンスが少ない。 1990年開始の全国11保健所地域住民14万人（研究開始当時年齢40－69歳）の多目的コホート研究では、複数回の食習慣・生活習慣に関するアンケート調査を行うとともに、がん・循環器疾患罹患を把握しており、疾病罹患前、罹患後の生活習慣の変化と予後の関係を検討することが可能である。そこで、本研究では、罹患前の食事や生活習慣を考慮したうえで、食事や生活習慣の罹患前後の変化と、がん・循環器疾患罹患生存者の、予後との関連を明らかにすることを目的としている。令和3年度は、多目的コホート研究の追跡調査により得られたデータを整理し、罹患情報の精査により罹患データベースの作成を行った。また、死亡データの取得により追跡情報を追加し、がん・循環器疾患生存者データベースの作成を行った。繰り返し調査の比較が可能な5年後調査と10年後調査を用いて、アンケート情報、食事・栄養摂取情報を付与し、がん生存者解析データベースの作成を行い、がん罹患前後の食事・栄養素摂取量の変化について検討を行った。その結果、5年後調査と10年後調査の両方に回答した73,192名のうち、その間に診断されたがん罹患者は、男性886人、女性646人であった。がん罹患者の診断前の食事と比較したところ、男性の診断後の食事において、エネルギー摂取と飲酒量において、より多くの減少がみられたが、そのほかの摂取量変化に差は見られなかった。

People's attitudes and behaviors are shaped by the region in which they live. In order to quantitatively understand the relationship between individuals and regions, this study constructed a multilevel geographical data that combines both types of information, conducted statistical analysis, and made the data publicly available. The study collected data on 30,000 residents of major cities in Japan, and based on detailed address information, clarified various regional differences in people's attitudes and behaviors, as well as the factors that have contributed to such regional differences. In addition, as related basic research, the impact of declining response rates in social surveys on regional analysis and the usefulness of new survey methods using the Internet environment were clarified.

Consistent and comparable health information across prefectures is necessary for monitoring progress in improving population health and reducing geographic health disparities in Japan. We applied a spatio-temporal Bayesian hierarchical model to examine long-term trends and variations in noncommunicable disease risk factors by prefecture, sex and age group. Prefectural mean BMI from 1975 to 2018 was almost consistently highest in Okinawa, and the rankings of prefectures in Shikoku and Kyushu increased to be equivalent to Hokkaido and prefectures in Tohoku. Global collaborative studies revealed the long-term trends and distribution of non-communicable disease risk factors in Japan and other countries.

The purpose of this study was to clarify the association of combined exposure to air pollution and surface heat with disease in subjects of the JPHC Study by more accurately assessing exposure using a geographic information system at the individual level. Among results to date, PM2.5 tended to be positively associated with mortality from cardiovascular disease. However, assessment of yellow sand and surface heat exposure requires further consideration at the individual level. While this evaluation of combined exposure to air pollution, yellow sand, and surface heat and disease requires further consideration of observation period and resolution, we have established a cohort platform which we can evaluate the association between combined environmental exposure and disease.

In order to investigate the transmission of tuberculosis infection, molecular epidemiology, in which genes of clinical strains isolated from patients are compared, is widely used. In this study, we visualized the correlation between spread of pathogens estimated from genetic analysis of the strain and spatial diffusion estimated from the spatial relationship (distance between residences) of the patients. Moreover, from people-flow data based on person-trip survey, we estimated, visualized, and compared how people are in contact with other people resident in surrounding areas. As a result, strong geographic anisotropy was monitored in the amount of contact of people that can be the background of epidemic of infection in a society.

In Japan today, there is a growing concentration of population in Tokyo and economic decline elsewhere. To understand the complex phenomenon of regional inequality, it is important to redefine the concepts of 'regional inequality of scale', which refers to the uneven geographical distribution of population and industry, and 'regional inequality of level', which focuses on regional differences in terms of income per population. The dilemma arises when populations move from low-income to high-income regions, with the latter becoming smaller while the former widens. Analysis of long-term changes and recent trends in regional inequality shows the following points. First, regional inequalities are found in income levels, educational opportunities, employment, marriage and childbirth, and health status. Second, socio-economic 'selective migration', such as education and income, leads to the reproduction of regional inequalities through changes in the composition of the regional population.

The aim of this study is to understand the geographical disparities of the health in Japan at small area levels and their formation process by using area indicators of residential places. First, various small area indicators such as areal deprivation index (degree of area poverty) and walkability index (measuring the degree of living by foot) were constructed. Second, we confirmed the trend toward widening relative disparities of various mortality rates during the period from 1995 to 2014. Third, we conducted analyses of the surveyed data of retrospective survey on residential move, and of the panel data of the elderly who live in different environments. The results indicated that the geographical disparities of health were formed through choosing and living in the environments of the residential places associated with health or heath behaviors, such as physical activity.

We have developed infrastructure to research the association between air pollution and disease. The research is based on the prospective JPHC Study.By adding the geographic information of each subject to their data record, we are now able to accurately evaluate their individual exposure to air pollution. As part of this research, we evaluated the validity of LUR (land use regression) models for nitrogen dioxide (NO2) based on routine and campaign monitoring data obtained from an urban area. We built a model based on routine monitoring data obtained from all sites (routine-LUR-All, 203 points) and a model based on campaign monitoring data (campaign-LUR, 150 points) within the city of this urban area. The routine-LUR-All model predicted NO2 concentrations (30 points) well (adjusted R2=0.68), and the predictions from this model were highly correlated with the measured NO2 concentrations at evaluation sites.

To prevent dementia, we investigated the process from social environments, economic factors, and individual factors including lifestyles and phyco-biochemical factors to the risk of atherosclerosis and dementia. The subjects were approximately 110,000 residents aged 40-69 years. Poor indicators of social environments and economics were associated with smoking, high sodium intake, imbalanced diets, physical inactivity, and they were also associated with the prevalence of obesity or underweight, hypertension and diabetes, and the risk of total mortality and incident stroke, independent of individual factors. Hypertension from the middle-life, diabetes, narrowing arterioles in fundus, smoking, high oxidation and inflammation markers, low fiber intake and history of stroke were associated with the risk of dementia.

The Kyoto City survey data of single residents over 65 years of age has been permitted by the Kyoto City Personal Information Protection Committee for our project to transfer the data from Excel format to Geographical Information System (GIS) data. With this data-transfer we can make the structure of problems of each regional community more visible and are able to share the useful data more easily among community actors (welfare institution staff and volunteers) via the digital map. By using the GIS, Community General Support Centers’ jobs can be streamlined as well as their policy making jobs. However various problems should be solved during the execution of our project, namely the development of human resources, infrastructure, and the way of data-management. The most critical one is about the protection of personal information.

Strong gender role norms is one of the significant social characteristics on Japanese society. In this research, we sought to examine the effect of gender role norm on health. One of our studies identified that living arrangement modified the positive associations between spouse loss and stroke risk, which differed by gender. Another study identified that work-family conflict was associated with poor self-rated health among middle-aged Japanese men and women; its health impact was relatively stronger among women, in particular economically disadvantaged women. Also, we identified that working part-time and being self-employed showed higher mortality risk when compared with full-time employment among middle-aged Japanese women. Identified gender differences in health suggested that those gender discrepancy could be influenced by the strong gender role norms in Japanese society. Our results suggest that public health approach taking account of gender norm would be important.

The region hit by the Great East Japan Earthquake is desperately struggling to make progress in the reconstruction process. This study, based on the relationship between a tangible cultural heritage site and intangible cultural heritage like festival that is closely tied with a local community and community members, is aimed to explore a number of measures for maintaining local historic environment and providing local cultural heritage with a modern role, for instance as a disaster mitigation base, and to gain knowledge about the survival of community, which is a foundation for the reconstruction process. From this study, we found the roles that local cultural heritage played when the disaster hit the community, and explore measures for the survival of historic environment after the living space is transferred by ‘Memory Mapping’.

Socio-economic inequality has become a major concern in contemporary Japan. Focusing on geographic dimensions of inequality, this research project first identifies two distinct concepts of regional inequality. The first type essentially captures uneven geographical distributions of focal phenomena, such as population and gross regional product; we call this “regional inequality in size.” The second type captures differences in derived data, such as income per capita or per household, across space; we call this “regional inequality in level.” Some of the major empirical findings are as follows: 1) the former type of inequality has generally increased while the latter declined across prefectures in the recent decades; 2) population growth has been concentrated in Tokyo alone since the 1980s, and is accompanied by selective migration of highly educated labor force; and 3) growing socio-economic and geographical inequalities in health are observed at multiple spatial scales.

The aim of this research is to develop GIS-enabled Japanese census geography and promote its applied research. Using the 2010 Population Census of Japan, which has been provided as open data, we created the GIS ready census database of Japan. We can easily draw census maps (social atlas) at any spatial units using this database. We used the GIS database to apply spatial analysis and spatial microsimulation models for estimating small area data, illustrating the segregated spatial patterns of foreigners’ residential location, and predicting the spatial pattern of university students’ residence following a campus relocation. Moreover we supported the construction of a commercial geodemographic product, Mosaic Japan 2010, and conducted applied research using this geodemographic product for marketing as well as in public sectors: education, crime, health and social deprivation.

The aim of this study is to develop areal deprivation indices (ADIs) at neighbourhood levels in the context of Japan and then to associate it with various health outcomes and mediating environmental factors. We proposed several ways to construct ADIs using small area statistics of Japanese population census and applied them to assess geographical inequalities of health using various datasets of health outcomes. As results, we identified higher areal deprivation levels are likely to worsen health comes, such as all-cause mortality, survival rates after cancer diagnosis and self rated health. We have argued the background of these associations and possibilities to advance the interdisciplinary efforts on health geography with the aid of GIS and geographical statistics in the society.

We sought to examine the association between areal characteristics and individual health among Japanese middle-aged men and women by using multilevel approach. Area deprivation level was associated with the higher mortality and morbidity after adjustment of individual SES factors. Other areal characteristics (i.e., stress level, social norm, levels of interest in health check-up) were also associated with individual health outcomes. Our results suggest that areal environment could be a crucial public health target.

The type and degree of contributions made by foreigners in Japan, a country that has started to show population decline, vary with their nationality and status-of-residence, and regional differences in this regard are not small. Since foreignersare engaged in a variety of occupations, such contributions in contemporary Japan are not necessarily conspicuous. The fertility of foreign women and women within international marriages is nearly equal to, or even lower than, that of Japanese women. The adoption of reliable support measures for foreigners by some of the local municipalities deserves our attention, while the social integration policies of the national government are insufficient and should be improved.

It is difficult to evaluate health policy like health education for metabolic syndrome. In this study, we aim to evaluate health policy using social capital as an indicator. Secondary dataset showed that it was important to distinguish bonding/bridging social capital. Our cross-sectional survey showed that exchanging of courtesies by community leaders to elderly people significantly reduced suicide intention. We have planned to conduct small intervention trial of exchanging of courtesies. The personnel in the investigated town were too busy to manage the trial due to big earthquake and tsunami, so we did small intervention of physical activity at a workplace alternatively.

This study aims to examine the geographic inequalities of health at a neighbourhood level in Japanese metropolitan areas by applying various spatial analysis techniques to micro data sets of Japanese adult population. As a result, not only compositional effects derived from the regional variations in population compositions of residential socio-economic status, but also contextual effects caused by socio-built neighbourhood environments significantly determine the geographic inequalities of health measured by self-rated health and other health-related behaviours. It is also revealed that the inequalities are structured by the social area distribution in the metropolitan areas. The result indicates the importance of public health policies to reduce deprivation and poverty concentrations as well as to create and maintain healthy neighbourhood environments.

The latest IPCC report officially recognized that global warming is induced by human activities and that evidences were reported by a number of scientific articles. The report raised public awareness on the discussion on how to use Earth environmental resources on the sustainable basis. Typical examples are global food security issues, conflicts between bio-fuel production from crops and food production and water resource issues. Growing public concern is critical to the conservation of global earth environment, because the control of human activities is an ultimate countermeasure. More rigorous and quantitative discussion materials, however, are crucially important in policy makings and investment for improving environmental quality, in addition to the attractive visualization. Global map on Human and Environment is a platform visualizing how human production and habitation activities change the landscape and resource uses from the past, present to the future based on quantitative integrated simulation results. The achievements of this study is (1) development of a simulation model integrating land-use (agriculture and urban), human production-consumption activities and international trading activities, (2) automated calibration of the integrated model using a variety of observation and statistical data. It can help reduce time and labor of revising the model whenever new data are available. In addition, a methodology of mapping urban and human settlements and road network are developed using a large archive of global satellite imagery, to complement the existing human-associated global data. (3) Metadata schema is developed so that distributed global earth observation data and statistical data etc can be retrieved. (4) Finally, future land-use change scenarios are proved according to the climate change scenario provided by the latest IPCC report.

This research project for the period of 2003-2005 academic years has attained a number of notable results. They will be published in a detailed way in the forthcoming book, but a part of major finding can be mentioned as follows. As a consequence of population aging due to fertility decline since the mid-1970s, the total population of Japan began to decrease in 2005. Its influence is considered to produce important influences on various affairs, but, from geographical point-of-view, the followings are noteworthy. Regarding family/household, trend towards nuclear family has been remarkable until the mid-1970s, but the recent movement is summarized as a diversification of family/household. Its spatial pattern is so complicated that we cannot describe it simply like distinction between the three largest metropolitan areas and the non-metropolitan (peripheral) areas. In addition, impact of declining fertility during the past decades on migration (particularly, long-distance migration) has appeared in the forms of decline of migration rate and spatial shrink of migration areas. Return migration (or, the so-called "U-turn migration) of young adults to peripheral areas has not shown a favorable progress, suggesting a difficulty in having an expectation that the return migration will contribute to solution of various issues therein in the age of depopulation. In addition, it is interesting to note, however, that massive retirement of the baby boomers is drawing nearer and a part of them may return to their homeland situated in the peripheral areas. It deserves s great attention from the perspective of population geography. Furthermore, with regard to immigrants from abroad who are expected to play an important role of compensating for decrease of majority population, a careful analysis focused on their migration pattern reveals that they tend to have a strong orientation to destinations with competitive industrial sectors and accumulation of co-ethics and international marriage also has a certain importance.

HIV/AIDSの多地域流行モデルを開発し、わが国のHIV/AIDSサーベイランス・データを用いて流行の空間的解析・予測を行った。研究は次に示すように5つの段階からなる。第1に、HIV/AIDSの簡便な流行モデルを、理論疫学モデルで典型的なSIR型モデルの形式をとる階差モデルとして定式化した。第2に、これまでの疫学調査等から、モデルに含まれる疫学パラメターの中で特定可能なものを識別・推計した。結果として、接触感染率のパラメターのみを経験的に推計する必要性が残された。第3に、HIV/AIDSサーベイランスのデータから都道府県別のHIV感染者数時系列データを復元した。ここでは1999年以降の感染症新法の関係で、感染者の住所が、居住地から報告機関所在地へ移動している点を、別資料を援用しながら補正した。第4に、この補正されたHIV感染者数時系列データを用いて、定式化した多地域流行モデルをキャリブレーションし、パラメターの推計値ならびに都道府県間での流行の関連性を確認した。ただし、都道府県によっては報告患者数が少なく、推計されるパラメター値の信頼性が乏しくなるため、カーネルスムージングの技法を援用した地理的加重回帰法(地理的加重ポアソン回帰モデル)によって接触感染率の地域別パラメターを推計した。第5に、人口予測資料を用いて2015年までの地域別流行推移を予測した。その結果、東京大都市圏が引き続き日本におけるHIV/AIDSの流行中心であり続けるが、同時に京阪神大都市圏が西日本各地の流行を推し進める新たなHIV/AIDS流行の中心となることが予測された。さらに、これら大都市圏の感染者と地方に居住する感受性者間での感染は、全国的なHIV/AIDS流行に大きく貢献しており、大都市圏の流行の抑制は、日本全体でのHIV/AIDS流行抑制と密接に関連することが示唆された。

The purpose of this research is to develop a support system for the Kusatsu Chamber of Commerce and Industry (KCCI) using Geographical Information Systems (GIS) and GeoComputation. The system provides Spatial Decision Support System (SDSS) based on spatial interaction models and location-allocation models based on new geocomputation methods. Basically this research will contribute to KCCI from the point of view of applied geography. The KCCI and Ritsumeikan University carried out the questionnaire on consumer behavior at large scale for all households in Kusatsu City in 2002, following the 2000 large consumer behavior survey. We constructed a system handling the huge database of consumer behavior based on the GIS. We also developed impact analysis methods for new large-scale retail shops and SDSS for branch location planning of small-scale retailers. These methods are based on the spatial interaction models (SIM) for consumer behavior and the spatial microsimulation. The SIM should be an origin-specific competing destinations model, also will be disaggregated by type-of-households and traffic modes, and so on. Using the spatial microsimulation making the best use of the information of the Population Census, the consumer behaviors of the households at each small area are simulated. We will provide the system for the KCCI. The KCCI will use this system for giving advises to the members who plan to make new branch shops using the WebGIS.

空間分析の近年のトレンドとして、地理的に局所的な分布特性を把握しようとする地理的ローカル分析への関心の高まりをあげることができる。本研究では、空間的流動量ないし空間的な選択肢の選択確率をモデル化する空間的相互作用モデルに着目し、モデルのパラメターに潜む地理的な変異を推計する方法論を提案した。空間的相互作用モデルについては、パラメターを発地ごとに推計するOrigin specificな推計により大幅な適合度の改善がみられ、かつそのorigin-pecificなパラメターは流動現象が発生する地域的な差異、空間的意思決定者の選好の地理的差異を示唆することが知られていた。しかし、従来のアプローチは空間的相互作用モデルのパラメターに潜むパラメター変異を部分的にしか捉えていない。なぜなら、空間的相互作用は発地とともに着地の空間的次元によって定義され、発地と着地の組み合わせによってもパラメターの変異が生じうるからである。かかる問題点を解決するために、本研究では地理的なパラメター変異を推計するノンパラメトリック技法であるGWR(地理的加重回帰法)を、空間選択モデル(発地制約型空間的相互作用モデル)に適用し、発地のみならず着地の空間的位置に依存したパラメター変異を推計する方法論を提案した。さらに、この課題を達成するために、ポアソン回帰モデルにおけるGWRの推計方法、空間的相互作用に適当な重み付けカーネル、over dispersionを考慮した適当なカーネルサイズ(バンド幅)の決定法、結果の視覚化にっいて、新たな方法論を整理した。本研究で提案した方法を、日本の人口移動データに適用し、経験的にも発地および着地の組み合わせに依存するパラメターの空間的変異を確認、および、その人口移動研究上の解釈を行った。また、他の空間的相互作用モデルにおける同様な拡張において議論・整理した。

Nowadays many of the urban areas in Asian countries give more priority to economic development than to environmental issues, which leads to the serious environmental deterioration. Information showing developing stages of urban area are generally restricted to published statistics by governments. Especially in Asian developing countries the problem is severe because of the lack of data accumulation. Thus it is difficult to collect cross-sectional urban environmental indicators under a common criteria. Another problem is the credibility of those data; many of the existing data are said to be unreliable. The investigators proposed an alternative method ; it was a method to gather information through remote sensing, and processed it on the Geographic Information System in units of the administrative area. DMSP (Defensive Meteorological Satellite Program)/OLS (Operational Linescan System) Stable Light Image (SLI) is available to detect low levels of visible - near infrared (VNIR ; 0.4 - 1.1μm) radiance at night by - clouds illuminated by moonlight - lights from cities, towns and industrial sites - gas flares - ephemeral events such as fires - lightning illuminated clouds with the resolution of 30 seconds. From the enormous archives, the investigators established temporal data sets in Asian region for 1992-3, 1996, 1998 and figured out impacts of - Asian economic crisis (1997) - stress in the marginal zone between India and Pakistan - temporal variability of fisheries in the Japan Sea (the Eastern Sea) through the analyses on these data sets. They also compared these data sets summed up in each province in China with some published statistics on socio-economic factors. Intensity of the nocturnal light showed high alterability for GDP and consumption of electricity (per km^2). The investigators concluded DMSP/OLS SLI was enough applicable to evaluate developing stages of urban area without any published statistics.

The purpose of this research is to develop a support system for the Kusatsu Chamber of Commerce and Industry using Geographical Information System (GIS), including also a monitoring and forecasting system for regional planning. While the former system describes the state and changes evident in the commercial environment of Kusatsu city (Shiga prefecture) in the 1990s, the latter predicts the impact of these changes on the commercial environment. The two systems are programmed to assist the Kusatsu Chamber of Commerce and Industry to make regional designs related to commercial environments. 1. Monitoring system : This system is based on a huge database made using various questionnaires about factors such as consumer behavior, use of car parks, visitors to the central shopping district and attitude of managements. This system is aided by GIS and provides a large resource of maps showing the actual patterns of the commercial environment in Kusatsu. This system also functions as a three-dimensional visualization of the market areas. 2. Forecasting system for fee impact related to commerce : This research introduces the conventional production-constrained spatial interaction model using attractiveness estimated by a log-linear model. This spatial interaction model is applied to consumer behavior to predict the impact of changes in commercial environments ; for example, location changes of large-scale retail shops, changes in road networks, changes in the distribution of demand etc. 3. Support system for the Chamber of Commerce and Industry. This research makes a comparison of the reports about commercial environments, as edited by the Kusatsu Chamber of Commerce and Industry in 1992. It also offers a view of the current changes occurring in Kusatsu city. Finally, this research attempts to make practical use of this support system at the Kusatsu Chamber of Commerce and Industry.

1. 文献研究による基本的な問題点の整理空間的相互作用モデルにおける空間単位問題は、1)このモデリングにふさわい空間単位を定義するアプローチと、2)空間単位の変更に伴う分析結果への影響をみるアプローチ、に大別できる。本研究では、主に後者のアプローチについて検討している。空間的相互作用モデルの説明変数は、主に距離と質量項に分けて考えることができる。それぞれの変数に対するパラメター推定値が、データ定義の変更によって異なってしまう統計学的な説明について検討した結果、1)集計化による誤測定、2)集計化による複数の変数の混交(共線関係)に問題を分解できることが分かった。前者は近年、立地配分モデル研究において注目をあびている空間データの集計化による距離推定誤差と密接な関係があり、後者は、過去に論争となったデータの空間的自己相関と空間的相互作用モデルのパラメター推定の問題と関連している。 2. GISを利用した実験データ実験的に問題を考えるためのデータ基盤として、パーソントリップ調査買物流動データと市区町村間人口移動データをとりあげた。ただし、数値地図のハンドリングの難しさから、GISを用いたネットワーク距離の利用は断念した。どちらも基本的な空間的相互作用モデルでのモデリングを行い、それぞれは改良の余地はあるものの、流動の基本的パターンはとらえていた。集計化による距離の誤測定問題は、いずれもトリップの集中の度合いを考慮した集計距離の利用が有効である。ただし、距離の逓減効果が比較的弱い(距離パラメター2前後)人口流動データの場合、あまり集計距離の違いによる影響は現れない。他方、距離の逓減傾向が強いPTデータの場合は、集計距離による違いが大きい。また、モデルの構造を複雑化させると、一般に集計化による結果の違いも複雑となる。
