Weight suppression (WS), the discrepancy between a person's highest ever and current body weight, has been found in a number of studies to be associated with the onset and maintenance of bulimia nervosa (BN). The current theories on the working mechanism hypothesize that individuals with BN might be caught in a (psycho)biobehavioral bind and suggest a circle of weight loss, weight suppression, weight gain, and binge eating that in theory should also apply to a broad spectrum of binge eating symptomatology. This study was intended to test the hypothesis that WS predicts current binge eating with a loss of control (BE+LOC) in a population-based sample. We used a population-sample of participants (N=3,512) who responded to a survey in a women's magazine. In a logistic regression analysis, WS did not predict current BE+LOC, in contrast to high diet activity in the past year. Possible explanations for the lack of association are discussed. Future studies are needed to specify the specific active ingredients in the relation between WS and BN.
体重抑制（WS）是一个人曾经达到的最高体重和当前体重之间的差异，许多研究发现它与神经性贪食症（BN）的发生和维持有关。目前关于其工作机制的理论假设 BN 患者可能陷入了一种（心理）生物行为困境，并提出了一个体重减轻、体重抑制、体重增加和暴食的循环，理论上也应该适用于广泛的暴食症状。本研究旨在测试体重抑制是否可以预测基于人群样本中当前伴有失控感的暴食（BE+LOC）。我们使用了对妇女杂志的一项调查做出回应的人群样本参与者（N=3512）。在逻辑回归分析中，体重抑制并不能预测当前的 BE+LOC，而过去一年的高节食活动可以预测。对缺乏关联的可能解释进行了讨论。需要进一步的研究来确定 WS 和 BN 之间关系中的具体有效成分。
