Note: STI= sexually transmitted infections, CI= confidence intervals, OR= odds ratios. Models were adjusted for sex and study site. Variables considered for the multivariate model for unprotected sex with last stable partner of HIV-negative or unknown status were: disclosure of HIV status to partner, time since HIV diagnosis, alcohol use, participation in HIV support groups, condom access, having a casual partner and STI. Variables considered for the multivariate model for unprotected sex with last casual partner were: education, time since HIV diagnosis, condom access, and forced sex.
