目的：本研究的目的是在一个非临床的女性样本中研究暴饮暴食的患病率和相关性，并研究超重状态是否与暴饮暴食的相关性不同。设计：基于自我报告的暴饮暴食状态的女性横断面比较（在这些进食事件中吃下大量食物和缺乏控制感）和超重状态（测量体重：超重定义为体重指数（BMI）大于或等于27.3 kg/m2）。受试者是817名来自社区的20- 45岁妇女，她们参加了一项为期三年的前瞻性干预研究，以检查预防年龄增长的方法。测量：在基线和三年随访时测量体重。自我报告的措施，暴饮暴食，节食的做法，饮食和运动行为，抑郁症，自尊和紧张的生活事件收集在三年follow-up.Results：暴饮暴食的患病率在过去的六个月是9%的正常体重的妇女和21%的超重妇女。暴饮暴食的频率很低（> 50%的暴饮暴食者每周暴饮暴食少于一次），并且体重状况没有显着差异。与非暴饮暴食者相比，暴饮暴食者报告了更多的节食行为，对体重和形状的极端态度，以及更高水平的抑郁和压力生活事件。暴饮暴食与习惯性饮食和运动行为无关。在多变量模型中，重量/形状重要性（比值比（OR）= 3.33; 95%置信区间（95% CI）= 2.10，5.29），抑郁症（OR = 1.73; 95%CI = 1.07，2.79）和故意减肥史（OR = 1.68; 95%CI = 1.03，1.13）与暴饮暴食几率的增加独立相关。在非临床样本中，与正常体重的女性相比，超重女性中暴食的流行率大约是正常体重女性的两倍，但具有相似的相关性（即节食、抑郁、体重/形状关注）。需要前瞻性研究来确定暴饮暴食、抑郁、节食和体重增加之间是否存在因果关系。
OBJECTIVES: The aims of the present study were to examine the prevalence and correlates of binge eating in a nonclinical sample of women and to examine whether associations differed by overweight status.DESIGN: Cross-sectional comparison of women based on self-reported binge eating status (large amount of food eaten and feelings of lack of control during these eating episodes) and overweight status (measured body weight: overweight defined as body mass index (BMI) greater than or equal to 27.3 kg/m(2)).PARTICIPANTS: Subjects were 817 women aged 20-45y from the community who enrolled in a three year prospective intervention study to examine methods for preventing age-related weight gain.MEASURES: Body weight was measured at baseline and three-year follow-up. Self-report measures of binge eating, dieting practices, eating and exercise behaviours, depression, self-esteem and stressful life events were collected at the three-year follow-up.RESULTS: The prevalence of binge eating in the past six months was 9% among normal weight women and 21% among overweight women. The frequency of binge eating was low (> 50% of binge eaters binged less than once per week) and did not significantly differ by body weight status. Compared to non-binge eaters, binge eaters reported more dieting practices, more extreme attitudes about weight and shape, and higher levels of depression and stressful life events. Binge eating was not related to habitual eating and exercise behaviours. In multivariate models, weight/shape importance (odds ratio (OR) = 3.33; 95% confidence intervals (95% CI) = 2.10, 5.29), depression (OR = 1.73; 95% Cl = 1.07, 2.79) and history of intentional weight loss episodes (OR = 1.68; 95% CI = 1.03, 1.13) were independently associated with increased odds of binge eating.CONCLUSIONS: Binge eating is about twice as prevalent among overweight women, compared to normal weight women, in a nonclinical sample, but has similar correlates (that is, dieting, depression, weight/shape preoccupation). Prospective research is needed to determine whether there are causal associations between binge eating, depression, dieting and weight gain.
