Who benefits from walkability? relationships between the built environment and neighborhood-based physical activity among subpopulations
Methods: A random cross-sectional sample of n=2006 adults (Calgary, Alberta) completed both a telephone-interview and a self-administered questionnaire. Physical activity-related information, sociodemographic, and health-related characteristics were captured. Usual weekly minutes of neighborhood-based walking, moderate-intensity, and vigorous-intensity physical activity were weighted by their metabolic equivalents and totaled. Objective built environment attributes underwent a two-staged cluster analysis which identified three neighbourhood types (HW: high walkable; MW: medium walkable; LW: low walkable). Generalized Linear Models were used to estimate the differences in total neighborhood-based physical activity (MET.minutes/week) between the neighborhood types within sociodemographic and health-status strata.
Results: With the exception of those ≥61 years of age, overweight, and dog owners, other residents of high walkable neighborhoods participated in higher amounts of physical activity compared with those residing in medium or low walkable neighborhoods after adjusting for covariates (p<.05).
Conclusion: Creating neighbourhoods with a highly connected pedestrian network, a large mix of businesses, high population density, high access to sidewalks/pathways, and many bus stops within walking distance does not appear to lead to subpopulation heterogeneity in physical activity levels and therefore is a potentially effective population health intervention.

Qualified on the content I am responsible for because: I am an Assistant Professor (Department of Community Health Sciences, University of Calgary) and a Senior Research Fellow (School of Population Health, University of Western Australia) My postgraduate/postdoctoral training is in Public/Population Health and Kinesiology and my current research focuses on understanding the relationships between the built environment and physical activity. I am a principal investigator on a CIHR-funded project investigating the causal pathways between the built environment and weight status.
