There were almost 700,000 excess deaths in the US from March 1, 2020, through February 28, 2021, resulting from two often counterbalancing mechanisms: those predicted by changes in unemployment rates occurring during this period, referred to here as the "recession effect," and those predicted by the "pandemic effect," which reflects direct consequences of SARS-CoV-2 infections and COVID-19, accompanying impacts on health and medical care, and other changes in mortality not caused by greater joblessness. Using data from the Centers for Disease Control and Prevention, this study decomposed total mortality in this period into pandemic and recession effects, with additional estimates by sex, race and ethnicity, age, and fourteen causes. Although the pandemic effect increased many types of mortality, the recession effect reduced most types of mortality. Without the recession effect, there would have been nearly 40,000 more deaths than actually occurred. However, there were disparate impacts, particularly for external causes. Vehicular and alcohol-related fatalities and homicides rose because of strong pandemic effects. In contrast, the recession effect accounted for a greater share of the rise in drug mortality. Offsetting pandemic and recession effects resulted in a decrease in the number of suicides. Understanding these diverse impacts provides useful lessons for policy efforts to mitigate the current and future health pandemics.
2020 年 3 月 1 日至 2021 年 2 月 28 日期间,美国有近 70 万人的死亡人数超出预期,这主要是由两种相互抵消的机制造成的:一是在此期间失业率变化所预测到的“衰退效应”,二是由 SARS-CoV-2 感染和 COVID-19 直接导致的“大流行效应”,同时还包括对健康和医疗的影响以及其他由失业率上升以外的因素导致的死亡率变化。本研究利用美国疾病控制与预防中心的数据,将这一时期的总死亡率分解为大流行效应和衰退效应,并进一步按性别、种族和民族、年龄以及 14 种死因进行了估计。尽管大流行效应增加了许多类型的死亡率,但衰退效应降低了大多数类型的死亡率。如果没有衰退效应,实际死亡人数将增加近 4 万人。然而,不同人群的影响存在差异,尤其是外部原因。由于大流行的强烈影响,机动车和酒精相关的死亡和杀人案有所增加。相比之下,衰退效应导致了药物死亡率上升的更大份额。大流行效应和衰退效应相互抵消,导致自杀人数减少。了解这些不同的影响为减轻当前和未来的健康大流行提供了有益的经验教训。
