BackgroundHealthy diet and physical activity self-management is important in maintaining weight loss and preventing weight regain after bariatric surgery. We aimed at evaluating covariates of healthy diet and physical activity self-management among patients undergone bariatric surgery using Health Action Process Approach (HAPA) model.MethodIn this cross-sectional study, 272 patients with a history of bariatric surgery were selected from the data registry of Tehran Obesity Treatment Study (TOTS). Data were collected using bariatric surgery self-management standard questionnaire (BSSQ), and items based on HAPA model for healthy diet and physical activity self-management. Data were analyzed using Path analysis and AMOS version 24.ResultsThe mean score of self-management was (32 ± 10SD). Coping planning construct (β = 0.22; pConclusionHAPA was applicable as a framework for interventions promoting healthy diet and physical activity self-management in patients who have undergone bariatric surgery.</div

Path analysis for healthy diet self-management showed that in a healthy diet, self-management, task and coping self-efficacy, outcome expectancies, and risk perception were significantly related to the behavioral intention of a healthy diet.
