• It is not well known how urban design may influence physical function in dense areas. • Walkability attributes were associated with the physical function of elderly men. • No associations were found among elderly women. 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. 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. 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. 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. Image, graphical abstract [ABSTRACT FROM AUTHOR]

Background: The built and social environments may contribute to physical activity motivations and behavior. We examined the extent to which the Theory of Planned Behavior (TPB) mediated the association between neighborhood walkability and walking. Methods: Two random cross-sectional samples (n = 4422 adults) completed telephone interviews capturing walking-related TPB variables (perceived behavioral control (PBC), attitudes, subjective norm, intention). Of those, 2006 completed a self-administered questionnaire capturing walkability, social support (friends, family, dog ownership), and neighborhood-based transportation (NTW) and recreational walking (NRW). The likelihood of undertaking 1) any vs. none and 2) sufficient vs. insufficient levels (≥150 vs. <150 minutes/week) of NTW and NWR, in relation to walkability, social support, and TPB was estimated. Results: Any and sufficient NTW were associated with access to services, connectivity, residential density, not owning a dog (any NTW only), and friend and family support. Any and sufficient NRW were associated with neighborhood aesthetics (any NRW only), dog ownership, and friend and family support. PBC partially mediated the association between access to services and NTW (any and sufficient), while experiential attitudes partially mediated the association between neighborhood aesthetics and any NRW. Conclusions: Interventions that increase positive perceptions of the built environment may motivate adults to undertake more walking. [ABSTRACT FROM AUTHOR]

PHYSICAL activity ,CYCLING - Abstract
• Different types of neighborhood design support different physical activities. • Neighborhood design was associated with participation in physical activity but not with the volume of physical activity undertaken. • Compared with curvilinear neighborhoods, neighborhoods with grid street patterns were more likely to have their adult residents undertake transportation walking and cycling, leisure cycling, active transportation, and vigorous-intensity physical activity. • Compared with curvilinear neighborhoods, neighborhoods with warped-grid street patterns were more likely to have their adult residents undertake transportation cycling, active transportation, and vigorous-intensity physical activity. • After statistical adjustment for reasons of residential choice and other sociodemographic characteristics, neighborhood design was associated with physical activity. Cross-sectional studies provide useful insight about the associations between the built environment and physical activity (PA), particularly when reasons for neighborhood choice are considered. Our study analyzed the relationship between levels of weekly transportation and leisure PA among 3 neighborhood designs, statistically adjusting for sociodemographic characteristics and reasons for neighborhood choice. A stratified random sample of adults (age ≥20 years) living in Calgary (Canada) neighborhoods with different neighborhood designs (grid, warped-grid, and curvilinear) and socioeconomic status completed a self-administered questionnaire capturing PA, sociodemographic characteristics, and reasons for neighborhood choice (response rate = 10.1%; n = 1023). Generalized linear models estimated associations between neighborhood design and transportation and leisure PA outcomes (participation (any vs. none) and volume (metabolic equivalent: h/week)), adjusting for neighborhood socioeconomic status, sociodemographic characteristics (gender, age, ethnicity, education, household income, marital status, children, vehicle access, dog ownership, and injury), and reasons for neighborhood choice (e.g., proximity and quality of recreational and utilitarian destinations, proximity to work, highway access, aesthetics, and sense of community). Overall, 854 participants had resided in their neighborhood for at least 12 months and provided complete data. Compared with those living in curvilinear neighborhoods, grid neighborhood participants had greater odds (p < 0.05) of participating in any transportation walking (odds ratio (OR) = 2.17), transportation and leisure cycling (OR = 2.39 and OR = 1.70), active transportation (OR = 2.16), and high-intensity leisure PA (≥6 metabolic equivalent; OR = 1.74), respectively. There were no neighborhood differences in the volume of any transportation or leisure PA undertaken. Adjustment for neighborhood selection had minimal impact on the statistical or practical importance of model estimates. Neighborhood design is associated with PA patterns in adults, independent of reasons for neighborhood choice and sociodemographic factors. Image, graphical abstract [ABSTRACT FROM AUTHOR]

- Abstract
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.

• Objective walkability was associated with lower activities with neighbors. • Space syntax walkability was negatively associated with social capital scores. • Walkable built environment may not necessarily be supportive of social capital. A rapidly growing body of literature has explored associations between urban design attributes, which are conducive to walking, and social capital. The current study aimed to build on the limitations of previous research. Specifically, this study estimated the associations between traditional and novel walkable built environment metrics and social capital among a sample of adults in Japan. Data (n = 1010) from a randomly selected cross-section of residents (40–69 years old) from two areas in Japan were included. Social capital was assessed by questionnaires. Several objective and perceived walkable built environment attributes were calculated. Covariate-adjusted multivariable linear regression models were used to estimate associations between neighborhood built attributes and the three social capital scores. Street connectivity was negatively associated with activities with neighbors (b = -0.21, 95% CI -0.31, -0.11). Perceived population density was negatively associated with all three social capital scores, including social cohesion, activities with neighbors, and social participation (b = -0.21, 95% CI -0.30, -0.11, b = -0.15, 95% CI -0.24, -0.06, and b = -0.16, 95% CI -0.29, -0.02, respectively). Traditional walkability and Walk Score® were negatively associated with activities with neighbors (b = -0.04, 95% CI -0.07, -0.00 and b = -0.09, 95% CI -0.15, -0.04, respectively). No significant associations were observed between perceived walkability and social capital scores. Space syntax walkability was negatively associated with social cohesion and activities with neighbors (b = -0.12, 95% CI -0.23, -0.01 and b = -0.11, 95% CI -0.21, -0.01, respectively). This study provided unique findings demonstrating that walkable built environments may not necessarily support social capital in ultrahigh-density Asian cities. [ABSTRACT FROM AUTHOR]

BUILT environment , *CANCER prevention , *HEALTH equity , *EQUALITY , *URBAN planning - Abstract
In this interdisciplinary article, we provided an evidence-based discussion on the role of the supportive built environment on cancer prevention. We also extended the theoretical thinking on the built environment-cancer links by raising possible equality challenges. Following the recent call in population-level interventions in cancer prevention, our aim is to encourage readers to think about the important potentials and limitations that are raised from the point of view of the supportive built environments in relation to cancer prevention. We focus on the key links between the built environment and cancer prevention strategies (primary, secondary, and tertiary) and discuss ways in which the built environment may reflect and contribute to inequalities in cancer. • The built environment can directly and indirectly impact cancer rates. • Different cancers may have the same but also different built environment determinants. • The science of how to change the built environment to improve cancer health is in its infancy.

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.
