The BCH-weighted regression accounts for uncertainty in GBV class assignment resulting from the latent class model by creating an expanded dataset with one record for each latent class for each subject and assigning a set of weights based on the classification errors. Regression analyses are conducted using survey data analysis methods with robust standard errors to account for the weights and for multiple records per subject.
Model for number of sex partners adjusts for age, nationality, income, household size, charge for sex, years in cohort, age at first sex, occupation, having a current intimate partner, and running out of money to survive in the past 3 months. Excludes 3 observations with missing data.
Model for self-reported unprotected sex adjusts for education, years in cohort, and having a current intimate partner. Excludes 1 observation with missing data.
Model for PSA adjusts for age, occupation, having a partner who drinks, having a partner who is wealthy, and having an intimate partner. Excludes 1 observation with missing data.
Model for combined outcome adjusts for income and charge for sex. Excludes 1 observation for missing data.
