Crude mortality rates and mortality rates standardized against a British reference population have been calculated for a group of 460 consecutive patients with eating disorders seen between 1971 and 1981 in a tertiary referral centre for eating disorders. Crude mortality rates were 3.3% and 3.1% in the anorexia nervosa and bulimia nervosa groups respectively. Standardized rates demonstrated a six-fold increase in mortality in the anorexia nervosa group. The most common cause of death in this group was found to be suicide, with the risk of death remaining high for at least eight years after initial assessment. Specific associations of increased mortality were: being in the lowest weight group at the time of presentation, and having recurrent hospital admissions for eating problems.
对1971年至1981年间在一家三级转诊进食障碍中心连续诊治的460例进食障碍患者计算了粗死亡率和根据英国参考人群标准化的死亡率。神经性厌食症组和神经性贪食症组的粗死亡率分别为3.3%和3.1%。标准化率显示神经性厌食症组的死亡率增加了六倍。该组最常见的死亡原因是自杀，在初次评估后至少八年死亡风险仍然很高。死亡率增加的具体相关因素为：就诊时处于体重最低组，以及因进食问题反复住院。
