In the United States, “Hispanic” was defined as any race of Hispanic or Latino ancestry. Other racial categories were defined as each respective race not of Hispanic or Latino ancestry.
All models were weighted according to the inverse probability of testing for COVID-19 calculated as a function of age, sex, date of study entry, race/ethnicity, symptoms (fatigue, headache, sore throat, chest pain, shortness of breath, persistent cough, diarrhea, abdominal pain, skipped meals/anorexia, hoarse voice, myalgias, delirium, loss of smell/taste, fever), and occupation as frontline healthcare worker (among overall participants).
Logistic regression model conditioned on age, sex, and date of study entry.
Additionally adjusted for body mass index (17-18.4, 18.5-24.9, 25-29.9, and ≥30 kg/m2), history of diabetes (no, yes), heart disease (no, yes), lung disease or asthma (no, yes), kidney disease (no, yes), cancer (active or in the past; no, yes), and smoking status (never/former smokers, current smokers).
Additionally adjusted for occupation as frontline healthcare worker (no, yes; among overall participants). For healthcare workers, the model was additionally adjusted for access to personal protective equipment (reuse or inadequate, adequate) and practice setting (inpatient, nursing homes, outpatient hospital clinics, home health sites, ambulatory clinics, other).
Additionally adjusted for personal contact with COVID-19 (no, suspected COVID-19, confirmed COVID-19).
