The coronavirus disease 2019 (COVID-19) pandemic has increased the risk of individuals developing eating disorders and has exacerbated existing eating disorders. This observational study investigated the impact of the COVID-19 pandemic on patients with clinical and subclinical eating disorders.
This study was conducted over a period of four years: two years before and after the onset of the COVID-19 pandemic in Japan. We recorded the number and types of consultations provided by the Eating Disorder Treatment and Support Center coordinator. For subgroup analysis, data were classified by age, body mass index, and source of consultation, including patients, families, and personnel. The Seasonal Decomposition of Time Series by Loess was used for time series analysis.
The total number of consultations increased after the start of the pandemic and peaked around the beginning of 2022, before subsequently falling despite the increase in the number of COVID-19 infections. A similar trend was observed in patients aged 10-29 years. The study period coincided with social isolation and school/college/university closures.
The number of eating disorder consultations increased after the start of the pandemic. Although COVID-19 infections persisted, the pandemic's impact was transient.
2019年冠状病毒病（COVID-19）大流行增加了个体患饮食失调症的风险，并加剧了现有的饮食失调症。这项观察性研究调查了COVID-19大流行对临床和亚临床饮食失调症患者的影响。
本研究历时四年进行：在日本COVID-19大流行开始之前和之后各两年。我们记录了饮食失调治疗与支持中心协调员提供的咨询数量和类型。为进行亚组分析，数据按年龄、体重指数和咨询来源进行分类，咨询来源包括患者、家庭和工作人员。采用局部加权回归法进行时间序列分解以进行时间序列分析。
大流行开始后咨询总数增加，并在2022年初左右达到峰值，随后尽管COVID-19感染人数增加，但咨询总数仍下降。10至29岁的患者中也观察到类似趋势。研究期间恰逢社会隔离以及中小学/学院/大学关闭。
大流行开始后饮食失调咨询数量增加。尽管COVID-19感染持续存在，但大流行的影响是短暂的。
