背景：新冠肺炎疫情防控措施，如封锁和自愿限制外出等，对人类压力和经济活动产生不利影响。特别是，这种压力可能导致自杀。目的：研究COVID-19导致的自杀死亡率。方法：我们将NIID模型应用于2009年10月至2020年9月日本全国男女自杀死亡人数。2011年3月11日袭击日本东部的大地震的影响被纳入估计模型。结果：2020年7月、8月和9月，男性和女性的自杀死亡率均显著高于男性。女性的比例高于男性。总共查明了810例超额死亡病例。讨论与结论：两个月内的超额死亡率是经PCR检测确认的COVID-19死亡人数的1.4倍。应根据自杀效应慎重选择应对措施。
Background: Countermeasures against COVID-19 outbreak such as lockdown and voluntary restrictions against going out adversely affect human stress and economic activity. Particularly, this stress might lead to suicide. Object: We examined excess mortality attributable to suicide caused by COVID-19. Method: We applied the NIID model to suicide deaths from October 2009 through September, 2020 for the whole of Japan for both genders. Effects of the great earthquake that struck in eastern Japan on March 11, 2011 were incorporated into the estimation model. Results: Significant excess mortality in suicide was found in July, August and September in 2020 for both genders. It was greater among females than among males. In total, 810 excess cases of mortality were identified. Discussion and Conclusion: Excess mortality during the two months was 1.4 times greater than the number of COVID-19 deaths confirmed by PCR testing. Countermeasures against COVID-19 should be chosen carefully in light of suicide effects.
