Abstract

This study sets out to examine whether there was a cross-sectional association between neighbourhood walkability and obesity in adults aged 18 to 64 years. The data source was the 2010/11 cycle of the National Population Health Survey merged with the 2011 Census and DMTI built environment data. A mediation analysis was undertaken to investigate whether physical activity was a mediator in the pathway between a measure of neighbourhood walkability and obesity. Multivariable regression results revealed no statistically significant associations between any of the neighbourhood walkability measures and adult BMI. Similar results were found for males and females. This study did not find that physical activity mediated an association between neighbourhood walkability and adult obesity.
