Abbreviations: SARS-CoV-2, severe acute respiratory syndrome coronavirus-2; OR, odds ratio calculated using multilevel logistic regression; BMI, Body mass index

^*Age, body mass index, insurance, limited English proficiency

^†Neighborhood deprivation index includes six indicators and ranges from 0 to 1 with 1 indicating more deprivation;

^‡Index of the concentration of extremes (ICE), higher values indicate higher proportion White residents.

^§Crowding defined as the proportion of residences with more humans than rooms in the house.

^∥Removed n=9 individuals with missing BMI due to lack of convergence.
