SummaryIntroductionMultiple factors are related to lower weight loss after bariatric surgery. This review and meta‐analysis evaluates the influence of several mental and behavioral factors on weight loss.MethodSix electronic databases were searched. Percentage excess weight loss (%EWL) was calculated for all moderator and non‐moderator groups of the variables: symptoms of depression, anxiety and binge eating, compliance, physical activity, quality of life, and body image. All moderators, surgery types, and follow‐up moments were analyzed separately.ResultsIn total, 75 articles were included in the review; 12 meta‐analyses were conducted. Higher postoperative compliance to follow‐up was associated with 6.86%–13.68% higher EWL. Preoperative binge eating was related to more weight loss at 24‐ and 36‐month follow‐up (7.97% and 11.79%EWL, respectively). Patients with postoperative binge eating symptoms had an 11.92% lower EWL. Patients with preoperative depressive symptoms lost equal weight compared to patients without symptoms.ConclusionDespite the high heterogeneity between studies, a trend emerges suggesting that the presence of postoperative binge eating symptoms and lower postoperative compliance may be associated with less weight loss after bariatric‐metabolic surgery. Additionally, preoperative depressive symptoms and binge eating do not seem to significantly impact weight loss.

精神和行为因素对减肥手术后体重减轻的影响：系统评价和荟萃分析

摘要简介多种因素与减肥手术后较低的体重减轻有关。本综述和荟萃分析评估了几种精神和行为因素对减肥的影响。方法检索了六个电子数据库。计算所有调节变量和非调节变量组的超重减轻百分比 (%EWL)：抑郁、焦虑和暴饮暴食症状、依从性、体力活动、生活质量和身体形象。所有主持人、手术类型和随访时间均单独进行分析。结果总共纳入 75 篇文章；进行了 12 项荟萃分析。较高的术后随访依从性与较高的 EWL 6.86%–13.68% 相关。术前暴饮暴食与 24 个月和 36 个月随访时体重减轻更多有关（分别为 7.97% 和 11.79% EWL）。术后有暴食症状的患者 EWL 降低 11.92%。与没有症状的患者相比，术前有抑郁症状的患者体重减轻相同。结论尽管研究之间存在高度异质性，但出现的趋势表明，术后暴食症状的存在和术后依从性较低可能与减肥代谢手术后体重减轻较少有关。此外，术前抑郁症状和暴饮暴食似乎并没有显着影响体重减轻。
