这项研究检查了患有暴食症 (BED) 的肥胖患者在治疗开始前一年的体重轨迹，并探讨了这些体重变化的潜在相关性。通过结构化访谈和自我报告问卷对一百三十 (N = 130) 名连续寻求治疗的肥胖 BED 患者进行了评估。在治疗前一年，寻求治疗的肥胖 BED 患者中有 83% (83%；n = 108) 体重增加，其中 65% (n = 84) 增加了具有临床意义的体重（大于或等于体重的 5%）。总体而言，参与者报告在治疗前 12 个月内平均体重增加百分比为 8%（16.6 磅），参与者的体重变化范围很大（从体重增加 52% 到体重减轻 13%）。大部分患者 (35%) 被归类为体重增加过多者（定义为去年体重增加超过 10%），报告称体重平均增加了 16.7%。低体重增加者（定义为体重增加超过 5%，但小于 10%）占样本的 29%，其特征是平均体重增加 6.9%。体重维持者/减肥者（定义为治疗前 12 个月内体重维持或减轻）占样本的 17%，据报告体重平均减轻 2.8%。这三组人目前的体重、饮食行为或饮食失调精神病理学没有显着差异。大多数寻求治疗的 BED 肥胖患者报告称，在前一年体重明显增加。这些发现为解释暴食症治疗研究中通常报告的适度体重减轻提供了重要背景。在这些研究中未能实现体重减轻可能会被重新解释为体重稳定并防止体重进一步增加。 (C) 2013 Elsevier Inc. 保留所有权利。
This study examined weight trajectories in obese patients with binge eating disorder (BED) during the year prior to treatment initiation and explored potential correlates of these weight changes. One hundred thirty (N = 130) consecutive, treatment-seeking, obese patients with BED were assessed with structured interviews and self-report questionnaires. Eighty-three percent (83%; n = 108) of treatment seeking obese BED patients gained weight, and 65% (n = 84) gained a clinically significant amount of weight (greater than or equal to 5% body weight), in the year preceding treatment. Overall, participants reported a mean percent weight gain of 8% (16.6 pounds) during the 12 months prior to treatment with a wide range of weight changes across participants (from a 52% weight gain to a 13% weight loss). A substantial proportion of patients (35%), categorized as High Weight Gainers (defined as gaining more than 10% of body weight during previous year), reported gaining an average of 16.7% of body weight. Low Weight Gainers (defined as gaining greater than 5%, but less than 10%) comprised 29% of the sample and were characterized by a mean gain of 6.9% of body weight. Weight Maintainers/Losers (defined as having maintained or lost weight during the 12 months prior to treatment) comprised 17% of the sample and reported losing on average 2.8% of body weight. These three groups did not differ significantly in their current weight and eating behaviors or eating disorder psychopathology. The majority of treatment-seeking obese patients with BED reported having gained substantial amounts of weight during the previous year. These findings provide an important context for interpreting the modest weight losses typically reported in treatment studies of BED. Failure to produce weight loss in these studies may be reinterpreted as stabilization of weight and prevention of further weight gain. (C) 2013 Elsevier Inc. All rights reserved.
