Socio-Contextual Factors: Moving Beyond Individual Determinants of Sexual Risk Behavior among Gay and Bisexual Adolescent Males.

This study investigated factors associated with sexual behavior that confers the greatest risk for HIV transmission (i.e., unprotected anal intercourse; UAI) among 52 sexually active gay and bisexual adolescent males in a Midwestern city ages 15-19. A logistic regression model found that ethnicity other than African American, more sexual partners in the past year, greater stigma towards homosexuality, and greater perceived peer sexual norms for risky behavior were significantly associated with UAI (x2 =27.96, df=5, p<.001; Nagelkerke R2 = 0.56). Implications for prevention interventions are discussed.
