We estimated changes in life expectancy between 2019 and 2021 in the United States (in the total population and separately for 5 racial/ethnic groups) and 20 high-income peer countries. For each country's total population, we decomposed the 2019-2020 and 2020-2021 changes in life expectancy by age. For US populations, we also decomposed the life expectancy changes by age and number of coronavirus disease 2019 (COVID-19) deaths. Decreases in US life expectancy in 2020 (1.86 years) and 2021 (0.55 years) exceeded mean changes in peer countries (a 0.39-year decrease and a 0.23-year increase, respectively) and disproportionately involved COVID-19 deaths in midlife. In 2020, Native American, Hispanic, Black, and Asian-American populations experienced larger decreases in life expectancy and greater losses in midlife than did the White population. In 2021, the White population experienced the largest decrease in US life expectancy, although life expectancy in the Native American and Black populations remained much lower. US losses during the pandemic were more severe than in peer countries and disproportionately involved young and middle-aged adults, especially adults of this age in racialized populations. The mortality consequences of the COVID-19 pandemic deepened a US disadvantage in longevity that has been growing for decades and exacerbated long-standing racial inequities in US mortality.
我们估计了 2019 年至 2021 年期间美国(总人口和 5 个种族/族裔群体分别)和 20 个高收入国家的预期寿命变化。对于每个国家的总人口,我们按年龄分解了 2019-2020 年和 2020-2021 年预期寿命的变化。对于美国人口,我们还按年龄和新冠病毒疾病 2019 年(COVID-19)死亡人数分解了预期寿命的变化。2020 年(1.86 年)和 2021 年(0.55 年)美国预期寿命的下降超过了同行国家的平均变化(分别下降 0.39 年和增加 0.23 年),并且不成比例地涉及中年 COVID-19 死亡人数。2020 年,美洲原住民、西班牙裔、黑人以及亚裔美国人的预期寿命下降幅度大于白人,中年人口的损失也更大。2021 年,白人人口的预期寿命下降幅度最大,尽管美洲原住民和黑人的预期寿命仍然低得多。美国在大流行期间的损失比同行国家更为严重,而且不成比例地涉及年轻和中年成年人,尤其是年龄在这个年龄段的种族化人口中的成年人。COVID-19 大流行的死亡率后果加深了美国在长寿方面的劣势,这种劣势已经持续了几十年,并加剧了美国死亡率中长期存在的种族不平等。
