Physical activity, physical function, and stages of change in older adults

Objectives: 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 recontemplation stages (21/0%). YPAS scores were higher and Up-and-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.
