A Structured Social-Media Health Support intervention Program after Bariatric Surgery.

Background: Social media networks have been found to provide emotional, instrumental, and social support, which may contribute to improved adherence to post-bariatric surgery care recommendations.

Objectives: To evaluate the impact of an online social media-based, healthcare professional-led, educational and support program on patients' long-term engagement with and adherence to follow-up guidelines, self-care recommendations, and weight management after bariatric surgery.

Methods: An observational cohort study, employing mixed methods, accompanied a 12-week interactive, structured, social-media psychoeducational intervention program delivered on Facebook. Program participants, who had undergone one bariatric surgery within the past 1-7 years and were at least 18 years old at the time of surgery, were invited to join the program via posts online. Interested individuals were provided information about the program and the accompanying evaluation study, and those who met requirements completed study questionnaires before and after the program. Questionnaires included demographic and anthropometric information; postoperative recommendations received and their clarity and implementation; attitudes towards recommendation adherence; and well-being. Daily system data on program engagement were collected from the Facebook website.

Results: Of the 214 participants enrolled in the program, 101 (80.2% female, mean age 43.8±9.1 years and mean BMI 30.2±6.8 kg/m2, 1-7 years after bariatric surgery) completed both baseline and end-of-program questionnaires and were included in the analysis. Following the program, improvements were observed in most aspects of participants' adherence to postoperative recommendations and well-being. Close to half of the participants (44.6%) reported reaching their postoperative target weight at the end of the program or maintaining it throughout the program. Video posts drew higher participant engagement than other media, and content about proteins received the highest number of reactions. However, participants' active engagement gradually declined over time.

Conclusions: Interactive health support on social media can positively enhance patient engagement, adherence to treatment recommendations, health outcomes, and overall well-being.
