Weight bias internalization, or the process of applying negative weight-related attitudes and beliefs to oneself, is an important construct in regard to patients pursuing bariatric surgery. Weight bias internalization (or internalized weight bias) has been previously associated with depressive symptoms and binge eating among pre-surgical bariatric patients. However, a gap in the literature exists pertaining to how certain eating behaviors may mediate the relationship between weight bias internalization and binge eating. The present study assessed the role of eating behaviors (i.e., cognitive restraint, disinhibition, and hunger) as mediators between weight bias internalization and binge eating symptoms when controlling for depression.
A total of 708 adults (M = 42.91; White = 95.3%; women = 79.4%) seeking bariatric surgery at a tertiary academic medical center in the Appalachia region of the USA were included in this retrospective study. Patients completed validated measures of weight bias internalization, eating behaviors, and depression as part of a routine, psychological evaluation in order to determine surgical clearance.
Disinhibition and hunger were significant mediators in the relationship between weight bias internalization and binge eating beyond the role of depressive symptoms alone.
Disinhibited eating, or the tendency to experience a loss of control and eating in response to negative emotions, as well as subjective feelings of hunger are important dimensions of eating, particularly as related to weight bias internalization and binge eating. Weight bias internalization is an important factor to consider among pre-surgical bariatric patients and warrants additional treatment considerations.
体重偏见内化，即对自己应用负面体重相关态度和信念的过程，是关注接受减重手术患者的一个重要构建。体重偏见内化（或内化的体重偏见）与术前减重患者的抑郁症状和暴食行为有关。然而，文献中存在一个空白，即某些饮食行为如何在体重偏见内化和暴食行为之间的关系中起中介作用。本研究评估了在控制抑郁的情况下，饮食行为（即认知控制、抑制失控和饥饿）在体重偏见内化和暴食症状之间的中介作用。
共有 708 名成年人（M=42.91；白人=95.3%；女性=79.4%）参加了这项回顾性研究，他们在美国阿巴拉契亚地区的一家三级学术医疗中心接受减重手术。作为常规心理评估的一部分，患者完成了体重偏见内化、饮食行为和抑郁的有效测量，以确定手术资格。
抑制失控和饥饿在体重偏见内化与暴食之间的关系中是抑郁症状之外的重要中介因素。
抑制失控的饮食行为，或体验到失去控制并在消极情绪下进食的倾向，以及主观的饥饿感是饮食的重要维度，尤其是与体重偏见内化和暴食行为有关。体重偏见内化是术前减重患者的一个重要考虑因素，需要进一步的治疗考虑。
