Weight suppression (WS), the difference in one's highest weight (excluding pregnancy) and current weight at current height, is associated with the onset of eating disorders. Previous research has explored the influence of WS in predominantly clinical, female samples. However, the transition to college is a particularly high-risk time for weight gain and the development of eating pathology and men with eating disorders often have higher premorbid weights. This study investigated the associations of WS and dimensions of eating pathology in an undergraduate sample (N=859) and examined the effect of gender. Results demonstrated that higher levels of WS were associated with more dietary restraint (p=0.004) and more frequent purging behaviors (p<0.001); WS was indirectly related to loss-of-control eating through dietary restraint for both men and women (p<0.001). Additionally, men with higher WS were more likely to engage in extreme weight control behaviors, such as vomiting and laxative abuse (p=0.036). Findings suggest that weight history might be especially important to assess in men at risk for disordered eating. This approach might be particularly beneficial with college students due to their heightened risk of eating and weight disturbances.
体重抑制（WS），即一个人在当前身高下的最高体重（不包括孕期）与当前体重之间的差值，与饮食失调的发病有关。以往的研究主要在临床女性样本中探讨了体重抑制的影响。然而，进入大学这一阶段是体重增加和饮食病理学发展的特别高危时期，而且患有饮食失调症的男性往往病前体重更高。本研究调查了一个本科样本（N = 859）中体重抑制与饮食病理学各维度之间的关联，并考察了性别的影响。结果表明，较高水平的体重抑制与更强的饮食限制（p = 0.004）和更频繁的清除行为相关（p < 0.001）；体重抑制通过饮食限制与失控饮食存在间接关联，这在男性和女性中均成立（p < 0.001）。此外，体重抑制水平较高的男性更有可能采取极端的体重控制行为，如呕吐和滥用泻药（p = 0.036）。研究结果表明，对于有饮食失调风险的男性，评估其体重史可能尤为重要。由于大学生饮食和体重问题的风险增加，这种方法对他们可能特别有益。
