Sociodemographic and psychiatric variables are based on W1 with the exception of sexual identity, which is based on W2. Reference categories for these variables were Female, White, 45 and older, Married / Partnered, $70,000 or more, South, Heterosexual, No, 0, 0, and 0. Race/Ethnicity, Education and Personal Income were not significant predictors in any model.
Each column represents a separate model and AORs were adjusted for all the sociodemographic and psychiatric variables in each column.
p < 0.05,
p < 0.01,
