OBJECTIVE:To assess the prevalence of night eating syndrome (NES) and binge eating disorder (BED) and their related behavioral and psychological correlates in persons who sought bariatric surgery. RESEARCH METHODS AND PROCEDURES:A consecutive series of 215 persons with extreme obesity (82% women, 70% European American) completed the Weight and Lifestyle Inventory and a semistructured interview as part of a pre-surgery behavioral/psychological assessment. Diagnoses for NES and BED were based on graded diagnostic criteria. RESULTS:Percentages of participants who met diagnostic criteria for NES by interview were 1.9% for the strictest definition and 8.9% across all definitions of NES. After interview, full DSM-TR criteria for BED were met by 4.2%; an additional 1.4% reported binge eating at least once per week. Self-reported prevalence of NES and BED were higher. Those with NES or BED had significantly more symptoms of depression and a greater history of psychological complications than the remaining sample. DISCUSSION:The prevalence rates of NES and BED among this population of bariatric surgery candidates were lower than expected based on previous reports. Findings and hypotheses regarding lowered prevalence rates are discussed.

研究方法和程序:连续215例极端肥胖者(82%为女性,70%为欧洲裔美国人)完成了体重和生活方式调查,并进行了半结构化访谈,作为术前行为/心理评估的一部分。 NES和BED的诊断基于分级诊断标准。
结果:通过面试满足NES诊断标准的参与者百分率是最严格的定义为1.9%,在所有NES定义中为8.9%。访谈后,满足BED的DSM-TR完整标准的比例为4.2%;另外有1.4%的人表示暴饮暴食每周至少吃一次。自我报告的NES和BED患病率较高。与其余样本相比,患有NES或BED的患者具有明显更多的抑郁症状和更大的心理并发症史。
讨论:该肥胖手术候选人人群中NES和BED的患病率低于以前的报道。讨论了关于降低患病率的发现和假设。
