Examining the role of serostatus disclosure on unprotected sex among people living with HIV.

Given the increasing prevalence of HIV, it is important to identify factors associated with safer sex behaviors between people living with HIV and their partners. Utilizing a diverse sample of 242 HIV-infected adults [n=69 men who have sex with men (MSM); n=68 men who have sex with women (MSW); n=105 women who have sex with men (WSM)], we examined the association between serostatus disclosure and unprotected anal or vaginal intercourse (UAVI) and the moderating effect of sexual behavior group on this association. Overall, 88.7% disclosed to their current partner. Approximately 18.8% of MSM, 17.7% of MSW, and 29.5% of WSM reported UAVI. Controlling for age, time since diagnosis, and partner serostatus, we found main effects on UAVI for disclosure and sexual behavior group; specifically, disclosure was inversely related to unprotected sex [AOR=0.09, 95% CI (0.02, 0.43), p<0.001], and MSM were less likely to engage in UAVI relative to WSM [AOR=0.11, 95% CI (0.17, 0.82), p<0.05]. However, the relationship between disclosure and UAVI was not moderated by sexual behavior group. Future strategies that aim to increase disclosure to partners may consider focusing on its value as a means by which to reduce sexual risk behavior.
