title: 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.
  
  
  CONCLUSIONS
  Higher stages were positively associated with physical activity and physical function. Age was a significant moderator variable affecting stage, physical activity, and physical function.
