Variation in National COVID-19 Mortality Rates Across Asian Subgroups in the United States, 2020

Abstract

Provisional U.S. national COVID-19 mortality data for the year 2020 analyzed by the CDC in March 2021 indicated that non-Hispanic Asians fared markedly better overall than other racial/ethnic minority groups-and marginally better than non-Hispanic Whites-in terms of age-adjusted mortality rates. However, Asians in the United States are composed of diverse array of origin subgroups with highly varying social, economic, and environmental experiences, which influence health outcomes. As such, lumping all Asians together into a single category can mask meaningful health disparities among more vulnerable Asian subgroups. To date, there has not been a national-level analysis of COVID-19 mortality outcomes between Asian subgroups. Utilizing final multiple cause of death data for 2020 and population projections from the U.S. Census Bureau's Current Population Survey Annual Social and Economic Supplement for 2020, crude and age-adjusted national COVID-19 mortality rates, both overall and stratified by sex, were calculated for the six major single-race Asian origin subgroups (Asian Indian, Chinese, Filipino, Japanese, Korean, and Vietnamese) and a catch-all seventh category that comprises the remaining Asian subgroups (Other Asians), contrasting them to the corresponding mortality rates of other racial/ethnic groups. A substantially more nuanced picture emerges when disaggregating Asians into its diverse origin subgroups and stratifying by sex, with Filipino males and Asian males outside of the six major Asian subgroups in particular experiencing markedly higher age-adjusted mortality rates than their White male counterparts, whether comparisons were restricted to their non-Hispanic subsets or not. During the COVID-19 pandemic and in the post-pandemic recovery, it is imperative not to overlook the health needs of vulnerable Asian populations. Public health strategies to mitigate the effects of COVID-19 must avoid viewing Asians as a monolithic entity and recognize the heterogeneous risk profiles within the U.S. Asian population.

The role of histological subtypes in the survival of patients diagnosed with cutaneous or mucosal melanoma in the United States of America

“…The predicted number of deaths for the same period is 5,080 among males and 2,570 among females. Between 2014-2018, the melanoma death rates for males and females were 3.4 and 1.4 per 100,000 respectively [2].…”

The Impact of COVID-19 on Life Expectancy among Asian American Subgroups

“…While population-level data are preferred, disaggregating the major subgroups at the national level requires that analysts deal with numerous data limitations: lack of information on specific subgroups in some sources, high rates of missing and misclassified ethnic identity in the data, and relatively small sample sizes (11). Although Xu (14) recently provided national mortality estimates for Asian American subgroups during the first year of the pandemic, his analysis relies on age-adjusted death rates, a metric that is less intuitive than life expectancy, particularly for comparisons across Asian American subgroups or between Asian Americans and other racial/ethnic groups. Life expectancy (typically calculated at birth) summarizes the mortality experience of a population at all ages during a specified year or period in a way that is independent of the population’s age distribution and indicates how long individuals could expect to live throughout their lifetimes under the mortality regime of the particular period.…”
