Non-White race tied to higher risk for COVID infection, severity


A US meta-analysis and systematic review of data on 4.3 million patients analyzed in 68 cohort and cross-sectional studies shows that, relative to White people, Black, Hispanic, and Asian populations were at higher risk for COVID-19 infection and admission to an intensive care unit (ICU) but were less likely to die of the disease.

The study, published yesterday in JAMA Network Open, was designed to uncover the link between socioeconomic determinants of health and racial disparities in COVID-19 outcomes.

A team led by University of California at San Diego researchers searched for COVID-19 studies that included data on race and rates of infection, disease severity, and socioeconomic status published from Jan 1, 2020, to Jan 6, 2021, well before the more transmissible Delta (B1617.2) variant was predominant in the United States.

The researchers used the Area Deprivation Index (ADI), which accounts for income, education, employment, and housing quality, to measure socioeconomic disadvantage, and the Urban Core Opportunity Index (UOI) to measure urbanicity. They examined clinical care quality through preventable hospital stays, ratio of patients to primary care physicians, and percentage of the uninsured.
