背景减肥手术后，体重恢复的终生威胁依然存在。行为影响被认为在这个问题上起到了调节作用。因此，我们试图在Roux-en-Y胃分流术(RYGB)后确定这些预测因素。方法在一家拥有既定减肥计划的大型三级医院，包括一家专门从事减肥医学的多学科门诊中心，以及两名减肥外科医生，我们邮寄了一份调查问卷给1117名RYGB术后的患者。其中203份(24.8%)已完成，并已退回，适合分析。如果受访者在RYGB后不到1年，他们就被排除在外。从受试者的病历中提取基线人口学史、术前贝克抑郁量表(BDI)和简明症状自评量表-18分；比较术前和术后幸福感评分。结果研究人群的平均年龄为50.6+/-9.8岁，其中女性147人(85%)，男性42人(18%)。女性和男性的术前体重分别为134.1±23.6 kg(295±-52lb)和170.0±29.1 kg(374.0±64.0lb)，与最低点相比P=15%。体重显著回升的独立预测因素是进食欲望增加(OR=5.1，95%CI1.83~14.29，P=0.002)，术后幸福感严重下降(OR=21.5，95%CI2.50~183.10，P
Background After bariatric surgery, a lifelong threat of weight regain remains. Behavior influences are believed to play a modulating role in this problem. Accordingly, we sought to identify these predictors in patients with extreme obesity after Roux-en-Y gastric bypass (RYGB).Methods In a large tertiary hospital with an established bariatric program, including a multidisciplinary outpatient center specializing in bariatric medicine, with two bariatric surgeons, we mailed a survey to 1,117 patients after RYGB. Of these, 203 (24.8%) were completed, returned, and suitable for analysis. Respondents were excluded if they were less than 1 year after RYGB. Baseline demographic history, preoperative Beck Depression Inventory (BDI), and Brief Symptom Inventory-18 scores were abstracted from the subjects' medical records; pre- and postoperative well-being scores were compared.Results Of the study population, mean age was 50.6 +/- 9.8 years, 147 (85%) were female, and 42 (18%) were male. Preoperative weight was 134.1 +/- 23.6 kg (295 +/- 52 lb) and 170.0 +/- 29.1 kg (374.0 +/- 64.0 lb) for females and males, respectively, p= 15% from the nadir. Independent predictors of significant weight regain were increased food urges ( odds ratios (OR)=5.10, 95% CI 1.83-14.29, p=0.002), severely decreased postoperative well-being (OR=21.5, 95% CI 2.50-183.10, p
