^aAlcohol consumption in the prior year: non-drinker (0 drinks/week), moderate drinker (0–14 drinks/week), heavy drinker (>14 drinks/week).

^bNondrinkers with ≤ 1 URAI partner as referent.

^cNondrinkers with >1 URAI partner as referent.

^dJoint robust Wald χ² test.

^eAdjusted for baseline (age (spline), race, ethnicity, education) covariates and time-dependent (illicit drug use, cigarette smoking, depression, sexually transmitted infection) covariates lagged one visit.

^fWeighted to account for confounding and selection bias by time-dependent covariates lagged one visit and adjusted for baseline covariates.
