Externalized weight bias (EWB), directed towards others, and internalized weight bias (IWB), directed towards the self, are thought to exacerbate obesity and disordered eating and may be important factors to assess and understand among individuals seeking bariatric surgery. This study examined clinical correlates (pre-surgical BMI, depressive symptoms, weight self-efficacy, and shape/weight overvaluation) of both EWB and IWB among individuals presenting for bariatric surgery with and without regular loss-of-control eating (LOC eating).
A total of 316 adults presenting for bariatric surgery completed established self-report measures to assess EWB, IWB, depressive symptoms, weight self-efficacy, and core symptoms of disordered eating including LOC eating and overvaluation of shape/weight.
IWB and EWB were not associated with pre-surgical BMI, age, or sex, but were both significantly higher among White than non-White participants. Adjusting for race, IWB and EWB were significantly associated with greater eating disorder psychopathology and depressive symptoms and with less weight-related self-efficacy. Participants who endorsed regular LOC eating (53.5% of the sample) endorsed significantly lower weight self-efficacy and higher IWB, EWB, depressive symptoms, and overvaluation of shape/weight.
Findings suggest that regular LOC eating is common among individuals seeking bariatric surgery and associated with a range of heightened eating disorder and psychosocial concerns including both IWB and EWB. Future research exploring the longitudinal significance of the relationship between these two forms of weight bias and LOC eating is indicated.
针对他人的外化体重偏见（EWB）和针对自身的内化体重偏见（IWB）被认为会加剧肥胖和饮食失调，对于寻求减肥手术的个体，评估和理解这些因素可能很重要。本研究检查了接受减肥手术个体的 EWB 和 IWB 的临床相关性（术前 BMI、抑郁症状、体重自我效能和对体型/体重的过度重视），这些个体分为存在和不存在常规失控性进食（LOC 进食）。
共有 316 名成年人接受了减肥手术，他们完成了既定的自我报告测量，以评估 EWB、IWB、抑郁症状、体重自我效能以及包括 LOC 进食和对体型/体重的过度重视在内的饮食失调的核心症状。
IWB 和 EWB 与术前 BMI、年龄或性别无关，但白人参与者的 IWB 和 EWB 均显著高于非白人参与者。在调整种族因素后，IWB 和 EWB 与更高的饮食障碍心理病理学和抑郁症状以及更低的体重相关自我效能显著相关。报告有规律的 LOC 进食（样本的 53.5%）的参与者的体重自我效能显著降低，而 IWB、EWB、抑郁症状和对体型/体重的过度重视显著升高。
研究结果表明，规律的 LOC 进食在寻求减肥手术的个体中很常见，与一系列更高的饮食障碍和心理社会问题有关，包括 IWB 和 EWB。需要进一步研究探索这两种形式的体重偏见与 LOC 进食之间关系的纵向意义。
