ABSTRACT

Objective: Internalized weight bias (IWB), or negative weight related self-evaluation, is associated with eating-disorder psychopathology and common among patients seeking bariatric surgery, but little is known about the clinical presentation of IWB post-operatively. This study examined IWB and clinical correlates among adult patients with loss-of-control (LOC) eating post-sleeve gastrectomy surgery.

Methods: Participants (N = 145) were sleeve gastrectomy patients seeking treatment for eating/weight concerns and experiencing regular LOC eating approximately 6 months following surgery. Eating-disorder features were assessed with the Eating Disorder Examination-Bariatric Surgery Version interview (EDE-BSV) and participants completed established measures assessing IWB, depression, and mental and physical components of quality of life.

Results: IWB was not associated significantly with percent excess weight loss, age, or gender, but White participants reported significantly greater IWB than Non-White participants. IWB was significantly associated with greater eating-disorder psychopathology, depression, and lower perceived mental quality of life. Hierarchical regression analysis revealed that IWB significantly predicted variance in eating-disorder psychopathology above and beyond other related variables.

Conclusions: Findings suggest that IWB is common and associated with a range of heightened eating-disorder and psychosocial difficulties among patients experiencing LOC eating following bariatric surgery. Future research exploring the longitudinal post-operative prognostic significance of IWB is recommended.

摘要

目的：内化体重偏倚 (IWB) 或负体重相关自我评价与进食障碍精神病理学有关，在寻求减肥手术的患者中很常见，但对 IWB 术后的临床表现知之甚少。本研究检查了袖状胃切除术后失控 (LOC) 进食成人患者的 IWB 和临床相关性。

方法：参与者 ( N = 145) 是袖状胃切除术患者，因饮食/体重问题寻求治疗，并在手术后约 6 个月经历定期 LOC 饮食。通过饮食失调检查-减肥手术版访谈 (EDE-BSV) 评估饮食失调特征，参与者完成了评估 IWB、抑郁以及生活质量的心理和身体成分的既定措施。

结果：IWB 与超重减轻百分比、年龄或性别没有显着相关性，但白人参与者报告的 IWB 显着高于非白人参与者。IWB 与更大的饮食失调精神病理学、抑郁症和较低的感知心理生活质量显着相关。分层回归分析显示，IWB 显着预测了饮食失调精神病理学的方差，超出了其他相关变量。

结论：研究结果表明，IWB 很常见，并且与减肥手术后经历 LOC 饮食的患者的一系列饮食失调和心理社会困难有关。建议未来研究探索 IWB 的纵向术后预后意义。
