Walkability is a critical component of built environments, yet there is still diverse conceptualization and measurement of the construct. The Walk Score® metric is one measure of walkability, which is widely used in scholarly, industry, and public domains. With increased interest in the use of Walk Score® as a research tool, it is necessary to examine the operationalization and scope of the measure. This scoping review examined how researchers utilized Walk Score® in walkability research, with specific attention to identifying limitations related to health outcomes as well as the use of the metric in non-health research contexts. Findings from the review provide a novel and critically nuanced understanding of how the assumptions and limitations of Walk Score® are addressed relative to socio-ecological aspects of walkability.

Evidence connecting health care expenditures with physical activity and built environment is rare. We examined how detailed urban form relates to mode specific moderate-to-vigorous physical activity (MVPA) and health care costs—controlling for transit access, residential choices/preferences, sociodemographic factors. We harness high resolution data for 476 participants in the Rails and Health study on health care costs, mode specific MVPA, parcel-level built environment, and neighborhood perception surveys. To account for dependencies among outcomes, structural equation modeling framework is used. A 1% increase in bike, walk, and transit-related MVPA was associated with lower health care costs by −0.28%, −0.09%, and −0.27% respectively. A one-unit increase in neighborhood walkability index correlates with a 6.48% reduction in health care costs. Indirect associations between residential choices, attitudes, and health outcomes through MVPA were also observed. The results suggest the potential to alter behaviors and lower health care costs through retrofitting neighborhoods. [ABSTRACT FROM AUTHOR]

The built environment characteristics associated with walkability range from neighborhood-level urban form factors to street-level urban design factors. However, many existing walkability indices are based on neighborhoodlevel factors and lack consideration for street-level factors. Arguably, this omission is due to the lack of a scalable way to measure them. This paper uses computer vision to quantify street-level factors from street view images in Atlanta, Georgia, USA. Correlation analysis shows that some streetscape factors are highly correlated with neighborhood-level factors. Binary logistic regressions indicate that the streetscape factors can significantly contribute to explaining walking mode choice and that streetscape factors can have a greater association with walking mode choice than neighborhood-level factors. A potential explanation for the result is that the image-based streetscape factors may perform as proxies for some macroscale factors while representing the pedestrian experience as seen from eye-level.

We draw on theoretical insights from criminology in using the Walk Score index to analyze walkability's relationship to spatial crime patterns on Los Angeles city blocks. Results from our first set of negative binomial regression models show that walkability had an especially strong linear effect on robbery rates: a 24% increase in the robbery rate accompanied a 10-point increase in Walk Score on a block, controlling for the effects of local businesses and sociodemographic characteristics. Our second set of models reveals that walkability exerted variable nonlinear influences on spatial crime patterns. Our final set of models suggests that the walkability–crime relationship might depend on neighborhood social organization: When walkability is high, low-income blocks might experience sharp rises in rates of predatory violence as compared with more advantaged blocks. This research highlights the importance of considering the mechanisms involved in walkability's impact on the spatial distribution of individual crime types. [ABSTRACT FROM AUTHOR]

This study explored associations between perceived neighborhood walkability and neighborhood-based physical activity (NB-PA) and assessed possible moderation effects of the amount of time spent in the home neighborhood and individual characteristics (i.e., educational level and health-related problems). In 2016 to 2017, 509 Dutch adults, living in the South Limburg area, were included. Context-specific PA levels were measured using the Actigraph GT3X+ accelerometer and the Qstarz BTQ1000XT GPS-logger. Perceived neighborhood walkability, level of education, work status, and health-related quality of life were measured with validated self-report instruments. Results showed that individuals with a lower level of education or health-related problems spent more time in the home neighborhood. The perceived neighborhood walkability only affected NB-PA for individuals spending a relatively large amount of time in their home neighborhood. PA-facilitating features in the home neighborhood, for example, aesthetics, were only associated with more NB-PA for individuals without health-related problems or with a higher level of education.

Interrelationships between neighborhood walkability, area disadvantage, and crime may contribute to the inconsistent associations between crime and walking. We examined associations between crime and walking, and tested for differences by neighborhood disadvantage while addressing these additional complexities. Participants (n = 6,680) from 200 neighborhoods spanning the most and least disadvantaged in Brisbane, Australia, completed a questionnaire and objective measures were generated for the individual-level 1,000-m neighborhood. Multilevel models examined associations between crime (perceived and objective) and walking (recreational and transport), and interactions tested for differences by neighborhood disadvantage. High perceived crime was associated with reduced odds of transport walking, whereas high objective crime was associated with increased odds of transport walking. Patterns did not differ by neighborhood disadvantage. In disadvantaged neighborhoods, the "negative" criminogenic attributes were insufficient to outweigh the "positive" walkability attributes, producing similar walking patterns to advantaged neighborhoods where residents were dislocated from local destinations but buffered from crime.

This article explores the role of the work environment in determining physical activity gained within and around the workplace. With most adults spending more than half of their waking day at work, the workplace is a promising venue for promoting physical activity. We used a sample of 147 employed women—median age = 53 years old; 42% meeting Centers for Disease Control and Prevention (CDC) physical activity recommendations—wearing a GPS device and accelerometer on the hip for 7 days to assess location and physical activity at minute-level epochs. We analyzed the association between geographic information systems (GIS) measures of walkability and greenness around the workplace and the amount of physical activity gained while in the work neighborhood. Our results showed that working in high walkable environments was associated with higher levels of moderate to vigorous physical activity while at work, and with higher moderate to vigorous physical activity gained within the work neighborhood. Increasing walkability levels around workplaces can contribute to increasing physical activity of employees. [ABSTRACT FROM AUTHOR]

Physical activity (PA) tends to decline with age, but changes are influenced by individual and contextual factors. Identifying the relative contributions of each may be useful in addressing inactivity. We studied the degree to which changes in the built environment were associated with changes in PA among young women maturing from adolescence to adulthood. We followed a cohort of young women who participated in the Maryland site of the Trial of Activity of Adolescent Girls in 11th grade (ages 16-17 years) and again at ages 22 to 23. Participants wore accelerometers for 1 week in 2009 and in 2015 and answered questionnaires about their daily lives. We found that living closer to mass transit, sports, and recreational facilities was associated with more moderate-to-vigorous physical activity (MVPA). Individual-level factors were strongly associated with MVPA as well. [ABSTRACT FROM AUTHOR]

A growing literature has indicated a relationship between social capital and certain aspects of the built environment with contributions from various disciplines, including environmental psychology, urban design, and health geography. In this systematic review and research synthesis, we summarize the literature in this domain using existing sociological and design frameworks to ascertain the effect of specific built environment domains on social capital. Our review shows that there is a significant relationship between social capital and the built environment, specifically between social cohesion and access to destinations/walkability. Positive relationships exist between social capital, design, and diversity, whereas the effect of population density on social capital is negative and unclear. We find significant methodological limitations and gaps in the published literature, including the absence of longitudinal studies and the use of a plethora of social capital and built environment measures.

There is growing evidence that communities can be designed to support physical activity, but it is important to understand whether neighborhood features related to health are also considered satisfactory by residents. The study aimed to determine if there is an association between perceived and objective neighborhood environment variables and neighborhood satisfaction. Adults (N = 1,726) were recruited from neighborhoods in two regions of the United States selected to vary on walkability and income. Perceived neighborhood environment was assessed using a validated scale, objective measures were constructed using geographic information system (GIS), and satisfaction was assessed using a 17-item survey. Participants reported greater satisfaction when they perceived their neighborhood as having greater pedestrian/traffic safety, crime safety, attractive aesthetics, access to destinations, diversity of destinations, park access, and lower residential density. Objective measures were not significant. The discrepant findings between perceived and objective environmental measures indicate that neighborhood satisfaction is a complex construct.

This article investigates the impact of the running environment on perceived satisfaction, restoration, and running participation based on a questionnaire distributed to 1,581 novice runners. The most frequently experienced impediments on running routes are poor lighting, unleashed dogs, and encounters with cyclists and cars. Regression analyses reveal that attractiveness and restorativeness are positively associated with the quality of the running surface and running in parks or outside towns and negatively by running on public roads in town, by running in larger cities (>250,000 inhabitants), and by other road users. However, attractiveness and restorativeness of running routes play only a minor role in the decision of how frequently to run. Practical considerations (proximity, threats) appear to have a larger impact on running frequency. Importantly, the most frequently mentioned impediments (poor lighting, cars, unleashed dogs) do not affect running frequency, whereas infrequent impediments (threats by other people) significantly affect running frequency.

In this article the author views on advancing translation and dissemination research and practice through the physical activity. The author views that the persistence of health disparities in physical activity need for more work on translation, dissemination, and implementation research. The author also views that the U.S. Centers for Disease Control and Prevention created the Physical Activity Policy Research Network in October 2004.

The association between the built environment (BE) and walking has been studied extensively in urban areas, yet little is known whether the same associations hold for smaller, rural towns. This analysis examined objective measures of the BE around participants’ residence and their utilitarian and recreational walking from two studies, one in the urban Seattle area (n = 464) and the other in nine small U.S. towns (n = 299). After adjusting for sociodemographics, small town residents walked less for utilitarian purposes but more for recreational purposes. These differences were largely explained by differential associations of the BE on walking in the two settings. In Seattle, the number of neighborhood restaurants was positively associated with utilitarian walking, but in small towns, the association was negative. In small towns, perception of slow traffic on nearby streets was positively associated with recreational walking, but not in Seattle. These observations suggest that urban–rural context matters when planning BE interventions to support walking. [ABSTRACT FROM AUTHOR]

Identifying the relevant geography is an ongoing obstacle to effectively evaluating the influence of neighborhood built environment on physical activity. We characterized density and diversity of destinations that 77 older adults experienced within individually representative Global Positioning System (GPS) activity spaces and traditional residential buffers and assessed their associations with accelerometry-measured physical activity. Traditional residential buffers had lower destination density and diversity than activity spaces. Activity spaces based only on pedestrian and bicycling trips had higher destination densities than all-mode activity spaces. Regardless of neighborhood definition, adjusted associations between destinations and physical activity generally failed to reach statistical significance. However, within pedestrian and bicycling-based activity spaces, each additional destination type was associated with 243.3 more steps/day (95% confidence interval (CI) [36.0, 450.7]). Traditional buffers may not accurately portray the geographic space or neighborhood resources experienced by older adults. Pedestrian and bicycling activity spaces elucidate the importance of destinations for facilitating active transportation. [ABSTRACT FROM AUTHOR]

The neighborhood influences on walking are well recognized, yet less is known about how the environment impacts sedentary behaviors. This study used a social-ecological model to examine the correlates of sitting time, independent of walking behavior. Objective built environment measures and self-reported community participation were examined for associations with sitting time for 1,179 residents in Perth, Western Australia. Neighborhood built environment and social factors were significantly associated with women’s sitting time only. In particular, the presence of community infrastructure was negatively associated with women’s weekday sitting (relative reduction = 0.951; p = .037), but statistical significance weakened after accounting for community participation (relative reduction = 0.951; p = .057). Community participation was independently associated with both women’s weekday and weekend sitting (both p < .001). More walkable neighborhoods may help limit women’s sitting time by providing better access to community infrastructure, as local venues may afford additional opportunities for social interaction and participation.

The main goal of this study is to analyze the influence of several environmental factors (temperature, precipitation, mode and duration of school transport, perception of physical activity [PA] opportunities, and perceived neighborhood walkability) on adolescent’s daily moderate to vigorous physical activity (MVPA) levels of two European mid-sized cities. Data were collected from a sample of 829 adolescents (49.7% Spanish; 55.2% females; 14.33 ± 0.73 years). Daily meteorological data were collected for the valid days for each subject and MVPA levels were assessed with Actigraph GT3X accelerometer during seven consecutive days. Data were analyzed using multilevel modeling. Warmer weather (p < .01), lower levels of precipitation (p < .05), and use of active school transport (p < .05) were significantly associated with higher MVPA levels. Environmental neighborhood perception did not show significant influence. Further efforts should be carried out to increase PA opportunities during colder periods, rainy days, and to promote the use of active transport [ABSTRACT FROM AUTHOR]

We investigated the influence of neighborhood built form on sense of community in Perth, Western Australia. It was hypothesized that sense of community would be stronger in individuals living in pedestrian-friendly neighborhoods. Multivariate linear regression models explored associations between walking and sense of community, with progressive adjustment for objective and perceived neighborhood characteristics. Sense of community was positively associated with walking for transport and positive perceptions of neighborhood quality, and negatively associated with residential density. The findings highlight the influence of local area perceptions on sense of community that appeared to be more important than objective environment characteristics. However, the latter may influence perceptions, and this requires investigation. [ABSTRACT FROM PUBLISHER]

The objective was to investigate associations between features of the physical environment and neighborliness. Measures of the physical environment, including sidewalks, front porches, traffic-calming devices, bars on windows, and the presence of litter or graffiti, were collected using a systematic audit instrument in 10 neighborhoods in Portland, Oregon. Generalized linear regression models were created to model the odds of increasing neighborliness given access to the physical-environment factors of interest. The authors observed a greater probability of higher levels of neighborliness as the total number of positive physical-environment characteristics increased (cumulative odds ratio [95% confidence interval] = 1.69 [1.16, 2.45]) and the results were unchanged after controlling for race, self-reported health, perception of safety, years of neighborhood residence, age of house, market value of house, and proportion of homeowners in neighborhood. Modifiable features of the physical environment may be one mechanism through which people can enhance neighborliness. [ABSTRACT FROM PUBLISHER]

Transit-oriented developments are touted as providing a variety of social benefits, but personal benefits to residents are underresearched. The authors surveyed 51 residents before and after a new light rail stop was constructed in their revitalizing Salt Lake City neighborhood. Residents anticipated and then later experienced increased housing and neighborhood economic values, enhanced sense of community, and improved neighborhood reputation. Residents experienced greater than anticipated pedestrian and child safety after rail service started. Compared with resident perceptions of walkable neighborhoods elsewhere, the Salt Lake residents perceived their neighborhood to be denser, and offering less land-use diversity and more crime safety problems. Perceived walkability increased, with residents reporting greater land-use diversity and neighborhood satisfaction after rail stop completion. However, residents said more stores, parks and trails, and trees would improve walkability. These results show the personal benefits residents desire to make transit-oriented living a satisfying residential alternative. [ABSTRACT FROM AUTHOR]
