Abstract：
OBJECTIVE: An unprecedented rise in eating disorder presentations has been documented in several countries during the COVID-19 pandemic. We explored this phenomenon by analyzing nationwide psychiatric admissions over 5 years, controlling for demographic variables.
METHODS: We retrospectively analyzed all hospitalizations in New Zealand with a primary psychiatric diagnosis from 2017 to 2021, using Poisson regression to calculate admission rates by diagnosis, before and during the pandemic. Using Fisher\'s exact test and Poisson modeling, national data were validated against a manually collected sample of eating disorder admissions.
RESULTS: Eating disorder admissions rose significantly during the pandemic (RR 1.48, p < 0.0001), while other diagnoses remained unchanged or decreased slightly. Anorexia nervosa in 10 to 19-year-old females drove increases, with persistent elevations noted in the 10-14 age group. Pandemic-associated increases were more striking for Māori (RR 2.55), the indigenous Polynesian population, compared with non-Māori (RR 1.43).
CONCLUSIONS: Eating disorder hospital presentations increased during the COVID-19 pandemic, while other psychiatric presentations to hospital remained relatively unchanged. Possible drivers include disrupted routines, barriers to healthcare access, altered social networks, and increased social media use. Clinical services require additional resources to manage the increased disease burden, especially in vulnerable pediatric and indigenous populations. Ongoing monitoring will be required to establish the time-course of pandemic-related clinical demand.

摘要：
目标：在COVID-19大流行期间，一些国家的饮食失调表现出现了前所未有的上升。我们通过分析超过5年的全国精神病患者来探索这种现象，控制人口变量。
方法：我们回顾性分析了2017年至2021年在新西兰进行主要精神病诊断的所有住院患者，使用泊松回归计算诊断的入院率。在大流行之前和期间。使用Fisher精确检验和泊松建模，针对人工收集的进食障碍入院样本验证了国家数据.
结果：在大流行期间，进食障碍入院率显着上升（RR1.48，p<0.0001），而其他诊断保持不变或略有下降。10至19岁女性的神经性厌食症增加，10-14岁年龄组持续升高。与流行病相关的增长对毛利人来说更为显著(RR2.55)，当地的波利尼西亚人,与非毛利人(RR1.43)相比。
结论：在COVID-19大流行期间，进食障碍医院就诊增加，而其他精神病患者到医院的报告相对没有变化。可能的驱动程序包括中断的例程，医疗保健障碍，改变了社交网络，增加社交媒体的使用。临床服务需要额外的资源来管理增加的疾病负担,特别是在脆弱的儿科和土著居民中。将需要持续监测，以确定与大流行有关的临床需求的时程。
