Retirement Health and Lifestyle Study: Australian Neighborhood Environments and Physical Activity in Older Adults

The aim of this study was to compare the walkability of neighborhood environments of older adults (65 years and above) living in the general community and retirement village settings, and to describe associations between walkability and the physical activity of participants. The study was conducted in a coastal region of Australia largely characterized by urban sprawl. In 2011-2012, 292 participant neighborhoods (400 m radius around each home) were audited using the Irvine-Minnesota Inventory. Having validated a local adaptation of this tool, we compared neighborhood environments in the two settings. We found no association between walkability of the built environment and walking behavior of participants. Although retirement village residents lived in more highly walkable environments, they did not walk more and their overall levels of physical activity were lower than those of community residents.
