Background: HIV+ men who have sex with men (MSM) represent the largest group of people living with HIV/AIDS in the U.S. It is important to understand sexual risk-taking behaviors that may be linked to poor health outcomes among these men and their partners. Models of HIV risk behavior that focus solely on personal factors have been demonstrated to be ineffective at explaining risk behavior. Rather, in order to fully understand sexual risk taking, it is important to examine the factors linked to high-risk sexual situations, and not solely the factors linked to potentially high-risk persons.

Methods: An ethnically diverse sample of 100 HIV+ MSM completed an 8-week structured sex diary that collected detailed information on recent sexual encounters. In total, information on over 250 sexual encounters was collected and analyzed. Random effects regression analysis was used to examine situational factors that were related to high HIV transmission risk sexual encounters.

Results: Analyses revealed that substance use by a sex partner, heightened feelings of emotional and sexual attraction toward a partner, discussions about HIV and condom use, and depressed affect were each associated with high HIV transmission risk episodes. Substance use during sexual encounters behavior frequently co-occurred with unprotected sex. Likewise, substance use was more likely to occur in episodes with HIV+ partners.

Conclusions: Situational factors play an important role in sexual risk-taking among HIV+ MSM. Researchers should place a greater focus on behaviors and characteristics of sex partners in order to comprehensively understand sexual risk-taking among HIV+ MSM.

Learning Objectives:
1. Define the role the situational factors in understanding sexual risk-taking behaviors. 2. Identify situational factors that should be considered in developing interventions for HIV+ MSM. 3. Recognize the importance of understanding behaviors and characteristics of sex partners in order to effectively intervene with HIV+ MSM.
