Abstract: The purpose of this study was to determine the associations between depression and the likelihood of enrollment in a health plan–sponsored physical activity program and pattern of program participation over 2 years; a secondary aim was to examine the association between participation dose and depression risk. There are no published studies on how depression influences participation in health plan–sponsored physical activity programs and how participation affects depression risk in older adults in nonresearch settings.
