title: Factors affecting exercise attendance and completion in sedentary older adults: a meta-analytic approach.
abstract: BACKGROUND
  Many different constructs are used currently in the literature to assess exercise adherence. This study examined whether the same or different variables predict exercise attendance and exercise completion among sedentary older adults.
  
  
  METHODS
  Thirty-seven randomized control trials were selected from articles published between 1980 and 2000 that tested exercise interventions for sedentary older adults. Block-entry, weighted, hierarchical meta-regression analyses were conducted.
  
  
  RESULTS
  Different factors predicted attendance and completion. Group-based (P < .05) and resistance exercise (P < .1) predicted higher attendance rates than individual-based and aerobic exercise. In contrast, facility-based exercise was associated with higher completion rates than homebased exercise (P < .1).
  
  
  CONCLUSIONS
  Results show that completing a program is not synonymous with good attendance. Program designers need to consider different strategies to boost both of these rates that need to be maximized to best benefit program participants.
