Weight stigma and weight discrimination are prevalent in the United States and binge eating has been found to be associated with these experiences in numerous studies. One issue with the current literature on weight stigma and binge eating, however, is that study samples are primarily female, resulting in a lack of understanding of this relationship among males. To address this gap, we examined potential sex differences in the association between weight stigma and binge eating, as well as mediators of this relationship. Specifically, we examined experiences of weight discrimination and weight stigma consciousness as predictors of binge eating, and we assessed whether these relationships were mediated by depression, perceived stress, and/or perceived control. Results showed that, among females and males, experiences of weight discrimination significantly predicted binge eating and depression mediated this relationship; perceived stress also mediated this association, but only among males, and perceived control did not mediate for either sex. Results also showed that, among males, the relationship between weight stigma consciousness and binge eating was mediated by depression and perceived control, but not perceived stress. Weight stigma consciousness was unrelated to binge eating among females. Together, these findings suggest that weight stigma constructs differentially impact females and males, thereby illuminating the possible need for consideration of sex as an important component of efforts to reduce weight stigma.
体重污名和体重歧视在美国很普遍，大量研究发现暴饮暴食与这些经历有关。然而，目前关于体重污名和暴饮暴食的文献存在一个问题，即研究样本主要是女性，因此缺乏对男性中这种关系的了解。为了解决这一差距，我们研究了体重污名和暴饮暴食之间的关联中潜在的性别差异，以及这种关系的中介因素。具体来说，我们考察了体重歧视和体重污名意识作为暴饮暴食的预测因素，评估了这些关系是否通过抑郁、感知压力和/或感知控制来介导。结果表明，在女性和男性中，体重歧视经历显著预测了暴饮暴食，抑郁则介导了这种关系；感知压力也介导了这种关联，但仅在男性中，而感知控制则没有为任何性别所介导。结果还表明，在男性中，体重污名意识与暴饮暴食之间的关系受抑郁和感知控制的影响，但不受感知压力的影响。体重污名意识与女性的暴饮暴食无关。综上所述，这些发现表明，体重污名结构对女性和男性有不同的影响，从而凸显了考虑性别作为减少体重污名努力的一个重要组成部分的必要性。
