体重抑制（WS），过去最高非怀孕体重和当前体重之间的差异，预测饮食失调的负面结果，但WS和相关体重结构的影响在非临床中年人群中研究不足。我们研究了WS（当前体重最低的重量）和他们的协会与饮食精神病理学的妇女年龄在50+.MethodResultsParticipants是一个以社区为基础的样本（N = 1,776，M-年龄=59）谁完成了人口统计学和饮食精神病理学问题，通过在线调查。WS、WE和WS x WE作为结果变量的预测因子进行了测试; BMI和影响体重的医疗条件得到了控制。WS和WE较高的个体最有可能参与当前的减肥尝试，在过去5年中节食，以及极端的终身限制。具有较高WS的个体更可能经历暴饮暴食，更频繁的体重检查，高估形状和体重以及终身禁食。WE较高的人更有可能报告饮食和节食对生活的负面影响。更高的WS和我们每个人都预测更高水平的跳过餐在lifetime.DiscussionThis新的研究调查了WS在中年妇女和介绍了一个新的概念的体重变化（我们），可能是更相关的老龄化人口的妇女往往会随着年龄的增长而增加体重。研究结果表明，在中年女性中，WS和WE作为与饮食精神病理学相关的因素进行调查是有用的。
ObjectiveWeight suppression (WS), the difference between highest past non-pregnancy weight and current weight, predicts negative outcomes in eating disorders, but the impact of WS and related weight constructs are understudied in nonclinical, midlife populations. We examined WS (current weightlowest weight) and their associations with eating psychopathology in women aged 50+.MethodResultsParticipants were a community-based sample (N = 1,776, M-age=59) who completed demographic and eating psychopathology questions via online survey. WS, WE, and WS x WE were tested as predictors of outcome variables; BMI and medical conditions that affect weight were controlled for.Individuals that were higher on WS and WE were most likely to engage in current weight loss attempts, dieting in the past 5 years, and extreme lifetime restriction. Individuals with higher WS were more likely to experience binge eating, greater frequency of weight checking, overvaluation of shape and weight, and lifetime fasting. Individuals with higher WE were more likely to report negative life impacts of eating and dieting. Higher WS and WE each predicted higher levels of skipping meals over the lifetime.DiscussionThis novel study investigated WS in midlife women and introduced a new conceptualization of weight change (WE) that may be more relevant for aging populations given that women tend to gain weight with age. The findings implicate the utility of investigating both WS and WE as factors associated with eating psychopathology in midlife women.
