Physical Activity, Physical Function, and Stages of Change in Older Adults

Abstract

OBJECTIVE: To characterize physical activity and physical function by stage of change and age in older adults. METHODS: One thousand two hundred thirty-four individuals completed The Yale physical activity survey (YPAS), stage of change for exercise, and the Up-and-Go physical function test. RESULTS: Most subjects were in the maintenance (50.4%) or precontemplation stages (21/0%). YPAS scores were higher and Upand-Go scores were lower as exercise stage increased. Physical activity and physical function scores were lower in older age groups. CONCLUSION: Higher stages were positively associated with physical activity and physical function. Age was a significant moderator variable affecting stage, physical activity, and physical function.
