Neighbourhood walkability, leisure-time and transport-related physical activity in a mixed urban-rural area

Abstract

Objectives: To develop a walkability index specific to mixed rural/suburban areas, and to explore the relationship between walkability scores and leisure time physical activity. Methods: Respondents were geocoded with 500m and 1,000m buffer zones around each address. A walkability index was derived from intersections, residential density, and land-use mix according to built environment measures. Multivariable logistic regression models were used to quantify the association between the index and physical activity levels. Analyses used cross-sectional data from the 2007-2008 Canadian Community Health Survey (n = 1158;≥18 y). Results: Respondents living in highly walkable 500 m buffer zones (upper quartiles of the walkability index) were more likely to walk or cycle for leisure than those living in low-walkable buffer zones (quartile 1). When a 1,000 m buffer zone was applied, respondents in more walkable neighbourhoods were more likely to walk or cycle for both leisure-time and transport-related purposes. Conclusion: Developing a walkability index can assist in exploring the associations between measures of the built environment and physical activity to prioritize neighborhood change. © 2014 de Sa and Ardern.
