The purpose of this study was to assess characteristics of individuals who died from anorexia nervosa by assessing the frequency with which anorexia nervosa is listed as a causal factor related to the death of individuals in the USA. Data from over 10 million death records (all National Center for Health Statistic registered deaths in the USA for 1986-90) were examined for mention of anorexia nervosa as a primary or contributing cause of death. Only 724 were found, which equals an average of 145 annual deaths, and a rate of 6.73 per 100,000 deaths. The age and sex distribution suggests two fatal forms of anorexia nervosa, an early-onset form comprising 89% women and a later form comprising 24% men. The findings suggest that the mortality risk from current anorexia nervosa may be lower than formerly supposed and that it is not confined to young adults and adolescents.
本研究的目的是通过评估神经性厌食症被列为与美国个人死亡相关的因果因素的频率，来评估死于神经性厌食症的个体特征。对超过1000万份死亡记录（美国国家卫生统计中心登记的1986 - 1990年美国所有死亡记录）进行了检查，以确定是否提及神经性厌食症作为主要或促成死亡原因。仅发现724例，平均每年有145例死亡，每10万人中有6.73例。年龄和性别分布表明神经性厌食症有两种致命形式，一种早发型，女性占89%，另一种晚发型，男性占24%。研究结果表明，当前神经性厌食症的死亡风险可能低于先前的推测，而且它并不局限于年轻人和青少年。
