| Aim: Men who have sex with men (MSM) tend to have mixed sex networks with men. Many MSM have regular male sex partners (RP) but that does not imply monogamy. Multiple male sex partnership (MMSP) is prevalent and predicts HIV transmission. Factors of MMSP among MSM with RP are under-studied. The present study investigated prevalence and associated factors of MMSP in the last three months among MSM having RP in Beijing, China. | ||||
| Method / Issue: In the cross-sectional study, inclusion criteria were Chinese men aged 18-60 years old living in Beijing and had had anal intercourse with at least one RP in the last three months (the index RP was the one involved in the most recent episode of anal intercourse if there were more than one RP). Participants were recruited through outreach and referrals. Prospective participants visited an NGO and were interviewed anonymously in a room with privacy ensured 251 (72.1% of those approached) provided written informed consent and completed the survey. | ||||
| Results / Comments: Besides the index RP, respectively 26.7% and 39.8% had had anal sex with another RP or non-regular male sex partner (NRP) in the last three months. Prevalence of MMSP in the last three months was 48.2%. Prevalence of unprotected anal sex (UAI) with the index RP was 38.2%. Regarding cognitive variables that were derived from Theory of Planned Behavior and adjusted for significant background variable (i.e., inhaled nitrites use in the last three months), perceived negative attitude toward MMSP (AOR=0.95), subjective norm against MMSP (AOR=0.93), proportion of peers having had only one RP (AOR=0.75),proportion of MSM having RP being monogamous (AOR=0.75) and behavioral control for not engaging in MMSP (AOR=0.88) were negatively associated with MMSP in the last three months. Perception that MMSP was inconsistent with one’s moral standard (AOR=0.86) and perceived direct social control (e.g. requests or reminders from significant others) against MMSP (AOR=0.98) were negatively associated with MMSP. Inter-personal factors including intimacy (AOR=0.98) and having a closed (monogamous) agreement with the index RP (AOR=0.52 reference: no sexual agreement) were negatively associated with MMSP having an in-between sexual agreement that extra-dyadic sex with another man are allowed to occur in the absence of UAI was positively associated with MMSP (AOR=4.86 reference: no sexual agreement). Non-significant interpersonal variables included indirect social control (e.g., feelings of obligation or responsibility to significant others) against MMSP and dyadic trust within regular partnership. Variables reflecting poor mental health status (e.g., higher score in CESD-10 Scale and GAD-7 Scale) were also shown to be risk factors (AOR=1.06 & 1.10) of MMSP. | ||||
| Discussion: MMSP of MSM with RP is an under-emphasized risk factor of HIV transmission among MSM with RP. Interventions are warranted but lacking. About half of MSM with RP had had MMSP. To reduce MMSP, we need to enhance related cognitions, build up moral norms, and reduce psychological problems (depression and anxiety). The concept of sexual agreement, which was associated with MMSP, has never been studied among Chinese MSM interventions may facilitate establishment of closed sexual agreement. | ||||
