(1) Background: Obesity (OB) is a frequent co-morbidity in Binge Eating Disorder (BED), suggesting that both conditions share phenotypical features along a spectrum of eating-related behaviors. However, the evidence is inconsistent. This study aimed to comprehensively compare OB-BED patients against OB individuals without BED and healthy, normal-weight controls in general psychopathological features, eating-related phenotypes, and early life experiences. (2) Methods: OB-BED patients ( = 37), OB individuals ( = 50), and controls ( = 44) completed a battery of standardized questionnaires. Responses were analyzed using univariate comparisons and dimensionality reduction techniques (linear discriminant analysis, LDA). (3) Results: OB-BED patients showed the highest scores across assessments (e.g., depression, emotional and stress eating, food cravings, food addiction). OB-BED patients did not differ from OB individuals in terms of childhood traumatization or attachment styles. The LDA revealed a two-dimensional solution that distinguished controls from OB and OB-BED in terms of increasing problematic eating behaviors and attitudes, depression, and childhood adversities, as well as OB-BED from OB groups in terms of emotional eating tendencies and self-regulation impairments. (4) Conclusions: Findings support the idea of a shared spectrum of eating-related disorders but also highlight important distinctions relevant to identifying and treating BED in obese patients.
(1) 背景：暴食症（Binge Eating Disorder，BED）常伴有肥胖（Obesity，OB），这表明这两种病症在与饮食相关的行为表现方面存在表型特征的重叠。然而，目前的证据并不一致。本研究旨在综合比较暴食症伴肥胖患者（OB-BED）、单纯肥胖患者（OB）和健康、正常体重的对照组在一般心理病理特征、饮食相关表现和早期生活经历方面的差异。(2) 方法：OB-BED 患者（n=37）、OB 患者（n=50）和对照组（n=44）完成了一系列标准化问卷。采用单变量比较和降维技术（线性判别分析，LDA）分析响应。(3) 结果：OB-BED 患者在所有评估中得分最高（例如，抑郁、情绪性进食和应激性进食、食物渴求、食物成瘾）。OB-BED 患者在童年创伤和依恋模式方面与 OB 患者无差异。LDA 揭示了一个二维解决方案，可根据不断增加的问题饮食行为和态度、抑郁和童年逆境，以及情绪性进食倾向和自我调节障碍，将对照组与 OB 和 OB-BED 区分开来，也可将 OB-BED 与 OB 组区分开来。(4) 结论：研究结果支持了存在一个与饮食相关障碍共享的谱系的观点，但也强调了识别和治疗肥胖患者暴食症的重要区别。
