Adjusted for the confounders of gender, age, presence of children in the household, income, and education. Presence of children was excluded from regression with number of children aged younger than 18 years in household as outcome.
The number of cases varies because of missing data.
Each index was a summative score of responses to survey questions, weighting each high-risk response 1 and each low- or no-risk response 0; thus, a higher index value indicates greater difficulty in social distancing, greater susceptibility, and less access to treatment.
