High levels of weight suppression have been associated with greater binge eating and weight gain as well as poorer treatment outcome in bulimia nervosa. This study examined the relationship between weight suppression and bulimia nervosa symptoms and explored how weight suppression might interact with body mass index (BMI) in accounting for level of symptomatology at presentation for treatment.
Participants were 64 women with threshold or sub-threshold bulimia nervosa. A clinical interview assessed binge eating and purging.
Weight suppression and the interaction between BMI and weight suppression predicted frequency of binge eating such that participants with low BMI and high weight suppression engaged in the most binge eating. High levels of weight suppression also predicted more frequent purging.
Additional research is warranted to examine mediators of these relationships.
体重抑制水平较高与暴食和体重增加以及神经性贪食症的治疗效果较差有关。本研究探讨了体重抑制与神经性贪食症症状之间的关系，并探讨了体重抑制如何与体重指数（BMI）相互作用，以说明治疗时出现的症状严重程度。
参与者为 64 名符合或不符合神经性贪食症标准的女性。临床访谈评估了暴食和催吐行为。
体重抑制以及 BMI 和体重抑制之间的相互作用预测了暴食的频率，即 BMI 低且体重抑制高的参与者暴食的次数最多。高水平的体重抑制也预示着更频繁的催吐行为。
需要进一步研究来检验这些关系的中介因素。
