COVID-19 had a huge mortality impact in the US in 2020 and accounted for most of the overall reduction in 2020 life expectancy at birth. There were also extensive racial/ethnic disparities in the mortality impact of COVID-19 in 2020, with the Black and Latino populations experiencing reductions in life expectancy at birth over twice as large as that of the White population. Despite continued vulnerability of these populations, the hope was that widespread distribution of effective vaccines would mitigate the overall impact and reduce racial/ethnic disparities in 2021. In this study, we quantify the mortality impact of the COVID-19 pandemic on 2021 US period life expectancy by race and ethnicity and compare these impacts to those estimated for 2020. Our estimates indicate that racial/ethnic disparities have persisted, and that the US population experienced a decline in life expectancy at birth in 2021 of 2.2 years from 2019, 0.6 years more than estimated for 2020. The corresponding reductions estimated for the Black and Latino populations are slightly below twice that for Whites, suggesting smaller disparities than those in 2020. However, all groups experienced additional reductions in life expectancy relative to 2020, and this apparent narrowing of disparities is primarily the result of Whites experiencing proportionately greater increases in mortality in 2021 compared with the corresponding increases in mortality for the Black and Latino populations in 2021. Estimated declines in life expectancy at age 65 increased slightly for Whites between 2020 and 2021 but decreased for both the Black and Latino populations, resulting in the same overall reduction (0.8 years) estimated for 2020 and 2021.
2020年,新冠疫情对美国的死亡率产生了巨大影响,导致2020年出生时预期寿命的总体下降大部分归因于此。2020年,新冠疫情的死亡率影响还存在广泛的种族/族裔差异,黑人和拉丁裔人口出生时预期寿命的下降幅度是白人人口的两倍多。尽管这些人群仍然脆弱,但人们希望有效疫苗的广泛接种能够减轻总体影响,并减少2021年的种族/族裔差异。在本研究中,我们按种族和族裔量化了新冠疫情对2021年美国时期预期寿命的死亡率影响,并将这些影响与2020年的估计值进行比较。我们的估计表明,种族/族裔差异依然存在,美国人口2021年出生时的预期寿命较2019年下降了2.2岁,比2020年的估计值多0.6岁。对黑人和拉丁裔人口的相应降幅估计略低于白人的两倍,这表明差异比2020年有所缩小。然而,与2020年相比,所有群体的预期寿命都进一步下降,这种差异的明显缩小主要是因为2021年白人死亡率的上升幅度相对大于黑人和拉丁裔人口死亡率的相应上升幅度。2020年至2021年期间,白人65岁时预期寿命的估计降幅略有增加,而黑人和拉丁裔人口的降幅则有所下降,导致2020年和2021年的总体降幅估计相同(0.8岁)。
