Objectives. We determined the prevalence, distribution, and correlates of US women's involvement in concurrent sexual partnerships, a sexual-network pattern that speeds population-wide HIV dissemination. Methods. We used sexual partnership dates reported by 7643 women in the 2002 National Survey of Family Growth to determine prevalence of concurrent sexual partnerships during the preceding 12 months. We examined associations between concurrency and sociodemographic characteristics and risk behaviors. Results. Prevalence of concurrent partnerships was 5.7% based on reported partnerships and 8.3% after adjustment for possible underreporting. Concurrency was associated with younger age (22 to 24 years: prevalence odds ratio [POR]=2.44) versus older age (40 to 44 years); marital status (formerly married: POR=6.56; never married: POR=3.81; vs married); Black race/ethnicity (POR=1.78); younger age at first sexual intercourse (12 to 13 years: POR=2.89) versus 18 years or older); having a nonmonogamous sexual partner (POR=6.96); having intercourse while ''high'' on drugs or alcohol (POR=1.61); binge drinking (POR=1.70); and crack or cocaine use (POR=2.72). Conclusions. The association of concurrency with nonmonogamous sexual partners and substance use suggests the existence of extensive sexual networks that link people at higher risk for HIV infection with increased opportunities for disseminating infection.
