Predictors of Exercise Maintenance 6 Months After Comprehensive Cardiac Rehabilitation.

PURPOSE The objectives of this study were (1) to assess the effects of a comprehensive education intervention on maintenance of knowledge, exercise behavior, heart-healthy food intake, self-efficacy, and health literacy 6 mo after comprehensive cardiac rehabilitation (CR), and (2) to identify predictors of exercise maintenance 6 mo after comprehensive CR. METHODS A prospective longitudinal study was conducted to test the effects of a structured educational curriculum in three CR programs in Canada. Participants completed surveys pre-, post-CR and 6 mo post-discharge to assess knowledge, heart-healthy food intake, self-efficacy, and health literacy. Exercise behavior was measured by number of steps/d using a pedometer. RESULTS One hundred twenty participants completed the final survey. Increases in disease-related knowledge and self-efficacy, as well as behavior changes (increases in exercise and heart-healthy food intake), were achieved in comprehensive CR and sustained 6 mo post-program. Exercise maintenance was predicted by changes in heart-healthy food intake, self-efficacy, health literacy, and exercise-related knowledge. CONCLUSIONS In this three-site study focusing on patient education for CR patients in Canada, the benefits of an education intervention in maintaining knowledge, exercise, healthy food intake, and self-efficacy were supported.
