To review the literature on the incidence and prevalence of eating disorders.
We searched Medline using several key terms relating to epidemiology and eating disorders and we checked the reference lists of the articles that we found. Special attention has been paid to methodologic problems affecting the selection of populations under study and the identification of cases.
An average prevalence rate for anorexia nervosa of 0.3% was found for young females. The prevalence rates for bulimia nervosa were 1% and 0.1% for young women and young men, respectively. The estimated prevalence of binge eating disorder is at least 1%. The incidence of anorexia nervosa is 8 cases per 100,000 population per year and the incidence of bulimia nervosa is 12 cases per 100,000 population per year. The incidence of anorexia nervosa increased over the past century, until the 1970s.
Only a minority of people who meet stringent diagnostic criteria for eating disorders are seen in mental health care.
回顾有关饮食失调发病率和患病率的文献。
我们使用了几个与流行病学和饮食失调相关的关键词在Medline上进行搜索，并查阅了我们找到的文章的参考文献列表。特别关注了影响研究人群选择和病例识别的方法学问题。
发现年轻女性神经性厌食症的平均患病率为0.3%。神经性贪食症在年轻女性和年轻男性中的患病率分别为1%和0.1%。暴饮暴食症的估计患病率至少为1%。神经性厌食症的发病率为每年每10万人中有8例，神经性贪食症的发病率为每年每10万人中有12例。在过去的一个世纪里直到20世纪70年代，神经性厌食症的发病率一直在上升。
在心理健康护理中，只有少数符合饮食失调严格诊断标准的人被发现。
