Abstract: Objective: To investigate the current self-management status among patients with obesity following bariatric and metabolic surgery and to analyze the influencing factors, thereby providing a theoretical basis for enhancing postoperative self-management. Methods: The study enrolled 124 patients with obesity who underwent bariatric and metabolic surgery at a tertiary grade A hospital in Chengdu by convenience sampling, from March 2022 to May 2024. Participants completed questionnaires that included a General Information Survey, the Bariatric Surgery Self-management Questionnaire, the eHealth Literacy Scale, and Brief 2-Way Social Support Scale. Results: The mean self-management ability score of patients after bariatric and metabolic surgery was 83.32±11.76. The mean scores for eHealth literacy and bidirectional social support were 25.35±6.40 and 35.50±7.71, respectively. Multiple linear regression analysis identified gender, monthly personal income, eHealth literacy, and bidirectional social support as significant predictors of self-management ability (all P<0.05). Conclusion: The self-management ability of patients after bariatric and metabolic surgery is at a high level. Their electronic health literacy and bidirectional social support can positively predict their self-management ability. Medical staff should focus on male patients and those with lower income levels in clinical management to improve their self-management ability in order to maintain the weight loss effect.
