The purpose of this study is to examine factors associated with increased suicide deaths during the coronavirus disease 2019 (COVID-19) pandemic in Japan using primary data from postmortem examinations.
We explored factors associated with suicides that occurred during the COVID-19 pandemic (February 2020 to December 2021) using data from 115 postmortem examinations of suicides that occurred in one city in the Kanto region between January 2017 and December 2021.
Multivariate analysis using graphical modelling and logistic regression analysis showed that both female sex (adjusted odds ratio: 3.732; 95% confidence interval: 1.044-13.345) and multiple mental disorders (adjusted odds ratio: 7.344; 95% confidence interval: 1.316-40.987) were significantly associated with suicide during the COVID-19 pandemic among the young age group (39 years or under).
The study results suggest that in addition to the factor of female sex previously identified, morbidity due to multiple mental disorders may be associated with the increased suicides in Japan during the COVID-19 pandemic. Furthermore, this study presented the new methodological possibility of analyzing background factors of suicide using postmortem examination data. In preparation for similar emergencies in the future, it is necessary to establish a system that provides care for multiple mental disorders and a continuous suicide-monitoring system that combines methods such as psychological autopsies with other methods.
本研究旨在利用尸检的原始数据，调查与日本2019冠状病毒病（COVID-19）大流行期间自杀死亡人数增加相关的因素。
我们利用2017年1月至2021年12月期间在关东地区一个城市发生的115例自杀尸检数据，探讨了与COVID-19大流行期间（2020年2月至2021年12月）发生的自杀相关的因素。
使用图形建模和逻辑回归分析的多变量分析表明，在年轻年龄组（39岁及以下）中，女性（调整后的优势比：3.732；95%置信区间：1.044 - 13.345）和多种精神障碍（调整后的优势比：7.344；95%置信区间：1.316 - 40.987）均与COVID-19大流行期间的自杀显著相关。
研究结果表明，除了先前确定的女性因素外，多种精神障碍导致的发病可能与日本COVID-19大流行期间自杀人数增加有关。此外，本研究提出了利用尸检数据分析自杀背景因素的新方法可能性。为应对未来类似的紧急情况，有必要建立一个为多种精神障碍提供护理的系统，以及一个将心理解剖等方法与其他方法相结合的持续自杀监测系统。
