Amount and Socio-Ecological Correlates of Exercise in Men and Women at Cardiac Rehabilitation Completion

Objective The aim of the study was to describe (1) the amount of physical activity (PA) in cardiac rehabilitation (CR) graduates by sex, and (2) the correlates of their PA. Design Secondary analysis of baseline data from a randomized trial was undertaken. Graduates were recruited from three CR programs. Participants completed a questionnaire, which assessed constructs from the socio-ecological model (i.e., individual-level, social- and physical-environmental levels). Physical activity was measured objectively using an ActiGraph GT3X accelerometer. Multilevel modeling was performed. Results Two hundred fifty-five patients consented, of which 200 (78.4%) completed the survey and provided valid accelerometer data. Participants self-reported engaging in a mean ± standard deviation of 184.51 ± 129.10 min of moderate-to-vigorous-intensity PA (MVPA) per week (with men engaging in more than women, P
