We examined prevalence, incidence, impairment, course, and diagnostic transitions for Diagnostic and Statistical Manual of Mental Disorders, fifth edition, eating disorders, overweight, and obesity in a high-risk sample of 1,952 young women (Mage = 19.7 years) who completed diagnostic interviews over a 3-year period. The baseline prevalence of any eating disorder was 13.3% and 25.4% showed onset (incidence) over 3-year follow-up. Baseline prevalence of overweight and obesity were 17.2% and 11.9%, respectively, with respective 3-year incidence rates of 18.3% and 6.8%. The average duration of eating disorders ranged from 2.2 to 5.0 months. Episode duration for overweight and obesity were 14.9 and 20.0 months, respectively. Most eating disorders (82%-96%) showed remission within 1 year; recurrence rates varied from 12% (atypical anorexia nervosa [AN]) to 44% (subthreshold bulimia nervosa). Three-year remission rates for overweight (53%) and obesity (34%) were lower, as was recurrence (15% and 9%, respectively). All eating disorders were characterized by a mixture of binge eating and compensatory weight control behaviors. Functional impairment was elevated for half the examined eating disorders and obesity. Diagnostic progression varied from 3% of those with atypical AN progressing to AN to 29% of those with subthreshold binge eating disorder progressing to binge eating disorder. Regarding diagnostic crossover, the most frequent pattern was shifting from a threshold to a subthreshold eating disorder, followed by shifting from a binge-related eating disorder to overweight. Results extend knowledge of the natural history of eating disorders and provide novel evidence of the relation between eating disorders and overweight/obesity.

在一项针对高危年轻女性的大型前瞻性研究中，饮食失调、超重和肥胖的患病率、发生率、损伤、病程和诊断进展和转变。


我们检查了《精神疾病诊断与统计手册》第五版、饮食失调、超重和肥胖的高危样本的患病率、发生率、损伤、病程和诊断转变，该样本包括 1,952 名年轻女性 （Mage = 19.7 岁） 在 3 年内完成诊断访谈。任何进食障碍的基线患病率为 13.3%，在 3 年随访中，25.4% 的发病率（发生率）。超重和肥胖的基线患病率分别为 17.2% 和 11.9%，3 年发病率分别为 18.3% 和 6.8%。进食障碍的平均持续时间为 2.2 至 5.0 个月。超重和肥胖的发作持续时间分别为 14.9 个月和 20.0 个月。大多数进食障碍 （82%-96%） 在 1 年内出现缓解;复发率从 12% （非典型神经性厌食症 [AN]）到 44% （阈下神经性贪食症） 不等。超重 （53%） 和肥胖 （34%） 的三年缓解率较低，复发率 （分别为 15% 和 9%） 较低。所有进食障碍的特征都是暴饮暴食和补偿性体重控制行为的混合。一半的受检饮食失调和肥胖症的功能障碍升高。诊断进展从 3% 的非典型 AN 患者进展为 AN 到 29% 的阈下暴食症患者进展为暴食症不等。关于诊断交叉，最常见的模式是从阈值转变为阈下饮食失调，然后从与暴饮暴食相关的饮食失调转变为超重。结果扩展了对饮食失调自然史的了解，并为饮食失调与超重/肥胖之间的关系提供了新的证据。 （PsycInfo 数据库记录 （c） 2024 APA，保留所有权利）。
