Although Binge Eating Disorder (BED) is associated with obesity and unstable weight and the diagnosis was originally predicated with the obese in mind, obesity is not a criterion for BED. In fact, BED is not uncommon in nonobese individuals. The aim of this study was to compare the psychopathology of obese (BMI >30) and nonobese individuals (BMI < 30) with BED.
Within a group of 174 individuals diagnosed with BED, 51 (29%) were classified as nonobese and 123 (71%) as obese. The Eating Disorder Examination (EDE) and Beck Depression Inventory (BDI) were administered to assess eating disorder psychopathology and depressive symptoms.
The nonobese BED group was significantly younger and was less likely to receive treatment. The obese group had more concerns about weight and reported more objective binge eating episodes. No differences were found on any other subscales of the EDE or BDI.
Our main finding was that there are more similarities than differences between the nonobese and obese individuals with BED. The severity of the psychopathology does not seem to be related to BMI. More awareness of the existence of nonobese individuals with BED is needed. Early detection and treatment may prevent the development of overweight and it's consequences.
尽管暴食障碍（BED）与肥胖和体重不稳定有关，且最初的诊断是针对肥胖人群，但肥胖并不是 BED 的诊断标准。事实上，非肥胖个体中也存在 BED。本研究旨在比较肥胖（BMI＞30）和非肥胖（BMI＜30）个体的 BED 患者的精神病理学。
在 174 名被诊断为 BED 的个体中，有 51 名（29%）被归类为非肥胖，123 名（71%）为肥胖。采用饮食障碍检查（EDE）和贝克抑郁量表（BDI）评估饮食障碍的精神病理学和抑郁症状。
非肥胖 BED 组患者明显更年轻，且接受治疗的可能性更小。肥胖组对体重的担忧更多，且报告的客观暴食发作次数更多。EDE 和 BDI 的其他任何子量表均无差异。
我们的主要发现是，肥胖和非肥胖的 BED 患者之间的相似之处多于不同之处。精神病理学的严重程度似乎与 BMI 无关。需要更多地了解非肥胖 BED 患者的存在。早期发现和治疗可能有助于预防超重及其后果的发生。
