Multiple sexual partners and their psychosocial correlates: the population-based AIDS in multiethnic neighborhoods...

In this study we examined multiple partners in a household probability sample of heterosexuals. Thirty-seven percent reported 2 or more partners in the past year, and 6% reported 5 or more partners. Significant interactions among gender, ethnicity, and relationship status revealed complex relations. African American men without a primary partner were the most likely to have multiple partners; ethnic minority women with primary partners were the least likely. Psychosocial factors associated with multiple partners were examined with the AIDS Risk Reduction Model (ARRM). Situational factors influenced how ARRM variables related to multiple partners. Perceived risk, commitment to monogamy, and communication were all important correlates. Prevention efforts must focus on increasing awareness of the risks of heterosexual transmission of HIV for people in dating relationships and on strengthening sexual communication skills with new partners.
