Trends in Angiotensin Receptor Blocker Use Among those at Risk for COVID-19 Morbidity and Mortality in the United States

Importance

Assessment of the use of angiotensin receptor blockers (ARBs) in the United States provides insight into prescribing practices, and may inform guidelines, policy measures and research during the COVID-19 pandemic.

Objective

To evaluate trends in ARB use among adults in the United States who have preexisting conditions and sociodemographic risk factors that put them at a higher risk of SARS-CoV-2 infection and COVID-19-related complications and mortality.

Design, setting and participants

This study uses the nationally representative cross-sectional data from the 2005-2018 National Health and Nutrition Examination Survey (NHANES). Participants included 39,749 non-institutionalized U.S. civilian adults who were 20 years and older and those with the most common preexisting conditions and risk factors reported among patients with COVID-19.

Main outcomes and measures

Use of ARBs in the prior 30 days from survey interview.

Results

ARB use ranged from 7.4% [95% CI, 6.5%-8.4%] to 26.2% [95% CI, 19.4%-34.4%] among those with one or two metabolic, renal, respiratory, and/or cardiovascular diseases. Among individuals with the three most common preexisting conditions in patients with COVID-19 including hypertension, diabetes and obesity, ARB use was higher among the elderly, females, non-Hispanic whites, and those with health insurance coverage.

Conclusions and relevance

In this nationally representative survey, ARB use was found to be widespread, but unevenly distributed among individuals with conditions and sociodemographic risk factors that place them at a higher risk of COVID-19 morbidity and mortality.
