Recent evidence suggests that incidence of Anorexia nervosa (AN) has remained stable over the last decades in Western Europe, while decreasing for Bulimia nervosa (BN). It is well-known that most individuals with an ED (Eating disorder) do not seek medical treatment.
The present study analyses hospitalizations related with EDs held in mainland Portuguese public hospitals between 2000 and 2014.
A retrospective observational study was performed gathering all inpatient episodes with primary or secondary diagnosis of ED. Number of patients, gender, mean age at discharge, suicide-attempts related hospitalizations, in-hospital mortality, length of stay, and mean charges were analyzed.
There were a total of 4,485 hospitalizations with an associated ED. AN was the most frequent ED (n = 2,806). Suicide attempt-related hospitalizations were most common among patients with BN (10.1% of BN hospitalizations) or AN (5.2% of AN hospitalizations).
AN has higher in-hospital mortality than BN. We observed a higher proportion of suicide related hospitalizations in BN when compared to AN. Although pica, rumination disorder, and psychogenic vomiting represent a smaller portion of all EDs, this study was the first to describe hospitalization trends for this set of EDs for a 15-year period, to the best of our knowledge.
最近的证据表明，在过去几十年中，西欧的神经性厌食症（AN）发病率保持稳定，而神经性贪食症（BN）的发病率则有所下降。众所周知，大多数患有饮食失调症（ED）的人都不会寻求医疗治疗。
本研究分析了 2000 年至 2014 年期间葡萄牙大陆公立医院中与 ED 相关的住院情况。
本研究是一项回顾性观察研究，收集了所有以 ED 为主要或次要诊断的住院患者。分析患者数量、性别、出院时的平均年龄、与自杀企图相关的住院治疗、院内死亡率、住院时间和平均费用。
共有 4485 例与 ED 相关的住院治疗。AN 是最常见的 ED（n=2806）。自杀企图相关的住院治疗在 BN（BN 住院患者的 10.1%）或 AN（AN 住院患者的 5.2%）患者中最为常见。
AN 的院内死亡率高于 BN。与 AN 相比，我们观察到 BN 中与自杀相关的住院治疗比例更高。尽管异食癖、反刍障碍和心因性呕吐在所有 ED 中所占比例较小，但据我们所知，这是首次对这一组 ED 进行 15 年住院趋势描述的研究。
