Geographic location, physical activity and perceptions of the environment in Queensland adults.

This study examines how physical activity and perceptions of the built environment differ by degree of urbanisation in Queensland, Australia. A statewide sample of adults (n=1208) completed a CATI survey assessing physical activity and perceptions of the environment in July-August 2005. Results indicate that residents in metropolitan areas were more likely to report the presence of shops and services, footpaths, heavy traffic and physical activity facilities than non-metropolitan residents. Although geographic location was not associated with achievement of sufficient levels of physical activity or walking, a notable interaction in the associations between both physical activity measures and the presence of footpaths in metropolitan and non-metropolitan areas was observed. This finding suggests the presence of a differential mechanism in terms of the relationships between physical activity and environmental supports by geographical location. Such effects require future investigation in terms of replication and understanding.
