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.
Participants ( = 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.
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.
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.
内化的体重偏见(IWB),或与体重相关的自我负面评价,与饮食失调的病理有关,并且在寻求减肥手术的患者中很常见,但对于术后 IWB 的临床表现知之甚少。本研究调查了减肥手术后出现失控性进食(LOC)的成年患者的 IWB 和临床相关性。
参与者(n=145)为减肥手术后因饮食/体重问题寻求治疗且术后约 6 个月仍经常出现 LOC 进食的袖状胃切除术患者。使用饮食失调检查-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、心理和身体生活质量的既定量表。
IWB 与体重减轻百分比、年龄或性别无显著相关性,但白人参与者的 IWB 显著高于非白人参与者。IWB 与更高的饮食失调病理、抑郁和更低的感知心理生活质量显著相关。分层回归分析表明,IWB 显著预测了饮食失调病理的变异性,超过了其他相关变量。
研究结果表明,IWB 在经历减肥手术后出现 LOC 进食的患者中很常见,并与一系列饮食失调和心理社会困难有关。建议未来探索 IWB 在术后纵向预后意义的研究。
