背景：肥胖和饮食失调通常被分开研究和治疗。虽然肥胖患病率的增加是众所周知的，但检查其与饮食失调同时发生（这也是一个公共卫生问题）非常重要，因为已知饮食失调行为会导致肥胖的发生和维持，反之亦然。 方法：数据来自 1995 年（n = 3001）、2005 年（n = 3047）和 2015 年（n = 3005）的大型横截面代表性全州社区样本。进行了分析。数据是通过结构化的自我报告访谈收集的，其中包括人口统计、健康相关、体重、身高和饮食失调行为问题。饮食行为问题评估了暴饮暴食、非常严格的节食/禁食和净化，并且源自饮食失调检查。对肥胖、饮食失调行为及其共现情况进行Logistic回归分析。 结果：1995年至2005年，肥胖或暴食或肥胖合并暴食的患病率均显着增加（每次比较P<0.001），并且从2005年至2015年继续显着增加（每次比较P<0.001）。 1995 年至 2015 年间增幅最大的是肥胖伴暴饮暴食的患病率（7.3 倍），或肥胖伴非常严格节食/禁食的患病率（11.5 倍）。从 1995 年到 2015 年，严格节食/禁食的流行率也显着增加（3.8 倍）。从 1995 年到 2015 年，暴饮暴食或伴有暴饮暴食的肥胖症患病率没有显着变化。结论：从 1995 年到 2015 年的 20 年间，全州范围内肥胖、暴食和非常严格节食/禁食的独立患病率有所增加，并且暴饮暴食共病和非常严格节食/禁食的肥胖症患病率增幅更大。这些发现支持需要采取更综合的方法来预防和治疗肥胖和饮食失调行为，即暴饮暴食和非常严格的节食/禁食。
BACKGROUND: Obesity and eating disorders are often studied and treated separately. While the increases in obesity prevalence are well known, examination of its co-occurrence with eating disorders, a problem also of public health concern, is important because eating disorder behaviors are known to contribute to obesity onset and maintenance, and vice versa.METHODS: Data from large cross-sectional representative statewide community samples of people in the years of 1995 (n = 3001), 2005 (n = 3047) and 2015 (n = 3005) were analyzed. Data were collected using a structured, self-report interview that included demographic, health-related, weight, height and eating disorder behavior questions. Eating behavior questions assessed binge eating, very strict dieting/fasting and purging, and were derived from the Eating Disorder Examination. Logistic regression analyses were conducted comparing prevalence of obesity, eating disorder behaviors and their co-occurrence.RESULTS: The prevalence of obesity or binge eating, or obesity with comorbid binge eating, each increased significantly from 1995 to 2005 (P < 0.001 for each comparison) and continued to increase significantly from 2005 to 2015 (P < 0.001 for each comparison). The highest increases from 1995 to 2015 were in the prevalence of obesity with comorbid binge eating (7.3-fold), or obesity with comorbid very strict dieting/fasting (11.5-fold). The prevalence of very strict dieting/fasting also increased significantly from 1995 to 2015 (3.8-fold). The prevalence of purging, or obesity with comorbid purging, did not change significantly from 1995 to 2015.CONCLUSION: There were statewide increases during the 20 years from 1995 to 2015 in the independent prevalence of obesity, binge eating and very strict dieting/fasting, and even higher increases in the prevalence of obesity with comorbid binge eating, and obesity with comorbid very strict dieting/fasting. These findings support the need for more integrated approaches to both the prevention and treatment of obesity and eating disorder behaviors, namely binge eating and very strict dieting/fasting.
