The Centre for Activity and Ageing offers multiple physical activity programs for the general public of older adults. Using a database of 670 registrants, we tracked 541 individuals in 12 programs at the same location over a 3-year period (1992-1995). We found program differences in gender and age mix, attendance patterns, and long-term adherence. Overall, we found a 68% attendance rate and adherence rates of 59%, 51%, and 43% at 6 months, 12 months, and 36 months, respectively. About 21% of participants tried out or transferred between programs during the tracking period, and these individuals were significantly more likely to remain at the center over 3 years. Longitudinal tracking demonstrates that program adherence is not necessarily the same as exercise adherence: older adults leave, rejoin, and switch exercise classes as their commitments and interests change. We project that 50% or more of older adults joining community programs will be long-term adherents to exercise.
