Roux-en-Y gastric bypass (RYGB) is a well-documented treatment of severe obesity. Attending postoperative educational programs may improve the outcome. The aim of this study was to evaluate whether participation in educational programs lasting 2-3 years after RYGB influences long-term weight loss, weight regain, physical activity, and compliance to multivitamin supplements.
The Bariatric Surgery Observation Study (BAROBS) is a multicenter retrospective, cross-sectional study 10-15 years after primary RYGB. Four hundred and ninety-seven participants answered questions regarding participation in postoperative educational programs. Participants were divided into frequent attendees (FA) and infrequent attendees (IFA) at the educational programs.
Ten to 15 years after surgery, a total weight loss (TWL) of 23.2 ± 11.6% were seen in the FA group vs 19.5 ± 12.6% in the IFA group, p < 0.001. Percent excess weight loss (%EWL) was 55.7 ± 28.9% vs 46.0 ± 31.1%, p < 0.001. Weight regain in percent of maximal weight loss for the FA was 32.1 ± 32.8% vs IFA 38.4 ± 40.0%, p = 0.052. No difference between the groups in compliance to multivitamin and physical activity.
Participants with frequent participation in group-based educational programs had better weight loss outcomes 10-15 years after RYGB and tended to have less weight regain. There was no difference between the two groups in participants compliance to recommended multivitamin supplements and physical activity.
Roux-en-Y 胃旁路术（RYGB）是一种治疗严重肥胖症的有效方法。参加术后教育计划可能会改善治疗效果。本研究旨在评估 RYGB 术后 2-3 年内参加教育计划是否会影响长期减重效果、体重反弹、身体活动和对多种维生素补充剂的依从性。
Bariatric Surgery Observation Study（BAROBS）是一项 10-15 年前进行的多中心回顾性、横断面研究，研究对象为接受原发性 RYGB 后的患者。497 名患者回答了关于参加术后教育计划的问题。将患者分为经常参加（FA）和不经常参加（IFA）教育计划两组。
术后 10-15 年，FA 组的总减重（TWL）为 23.2±11.6%，IFA 组为 19.5±12.6%，p<0.001。超重百分比损失（%EWL）为 55.7±28.9%，IFA 组为 46.0±31.1%，p<0.001。FA 组体重反弹百分比为最大减重的 32.1±32.8%，IFA 组为 38.4±40.0%，p=0.052。两组在多维维生素和身体活动的依从性方面没有差异。
经常参加团体教育计划的患者在 RYGB 术后 10-15 年内减重效果更好，体重反弹的倾向更小。两组患者在多维维生素补充剂和身体活动的依从性方面没有差异。
