Heart Disease, Physical Activity Trajectories, and Gender

Objectives: The first purpose was to identify distinct physical activity growth trajectories for light and moderate to vigorous physical activity (PA) after hospitalization for heart disease (i.e., to identify sub-groups of patients whose PA trajectories are similar to each other, but different from patients in other PA trajectory groups). The second purpose was to determine if gender predicted sub-group membership for each PA intensity. Design and Setting: Participants (N=554) completed a questionnaire in hospital and at 2, 6, 12, and 24 months after hospitalization. Results: Latent class growth curve analyses showed two classes of patients emerged for light intensity PA that were labeled Inactive Maintainers-Light (72.2% of the sample) and Low Active Maintainers-Light (27.8%). For moderate to vigorous PA, 87.8% of the sample was labeled Inactive Maintainers (i.e., remained inactive for the entire 2-year period), whereas 12.2% were labeled Active Maintainers (i.e., remained active for the 2-year period). Gender did not predict light intensity PA group membership, however, females were significantly more likely to be in the Inactive Maintainer for moderate to vigorous PA compared to males (odds ratio = 3.47). Conclusion: The association between gender and PA trajectories after hospitalization for heart disease may be intensity dependent.
