Concurrent Sexual Partnerships and Elevated Risk for HIV among Men Who Have Sex with Men in Southwest China
Methods: We used respondent-driven sampling (RDS) to recruit 780 males aged ≥ 18 who reported having anal sex with a male in the past 3 months in Kunming and Nanning. Interviews were conducted face-to-face using a structured questionnaire. Data analyses used RDS Analysis Tool and STATA-13.
Results: In the past three months, 26% of respondents had a concurrent female partner, 55% had concurrent male partners, and 20% had ≥5 concurrent partners. Levels of consistent condom use were lowest for sex with female partners (35%), followed by regular male partners (70%), casual male partners (81%), and male commercial partners (83%). 35% reported ever experiencing sexually transmitted infection (STI) symptoms.
Sexual concurrency was associated with decreased consistent condom use with male regular partners (OR=0.51; P<0.01) and male casual partners (OR=0.24, P<0.05). Having ≥5 concurrent partners was associated with decreased consistent condom use with male regular partners (OR=0.24; P<0.001) and male casual partners (OR = 0.45, P<0.05), and increased likelihood of experiencing STI symptoms (OR=1.86, P<0.01).
Conclusions: High rates of concurrent partnerships, having sex with both males and females, and limited condom use highlight the need for targeted interventions addressing HIV risks for MSM.
