In this analysis, participants in the United States National Health and Nutrition Examination Survey (NHANES) 2011-2016 2 aged ≥ 20 years were included. There were minor differences in the percentage of people with ≥ 1 established and ≥ 1 any risk factor according to sex, ethnicity, education, and income level, but the percentages remained around 60% and 75%, respectively. This is the first study to estimate the proportion of the Americans in the general population at risk from severe COVID-19 illness using data from a nationally representative survey. 4 Our study shows that obesity and hypertension are the leading risk factors for severe COVID-19 illness, especially in those aged < 50 years.	./cache/cord-283917-jumgb0hs.txt	./txt/cord-283917-jumgb0hs.txt
