Factors associated with concurrent sexual partnerships among men who have sex with men in Yangon, Myanmar.

Abstract

ABSTRACTMen who have sex with men (MSM) are considered to be one of the groups most at risk of contracting HIV. However, to date, information regarding MSM’s sexual behaviors and the risk factors for their concurrent sexual partnerships (CSP) have not been known in Myanmar. This study aimed to identify factors associated with CSP among MSM.A cross-sectional study was conducted from September to October 2011 in Yangon, Myanmar. In total, 353 males who had self-reported sex with men were recruited using respondent-driven sampling method. Descriptive statistics and multivariate logistic regression analysis were performed. In total, 61.0% of the MSM reported having CSP. MSM who practiced sex trading in the past six months (adjusted odds ratio8.32; 95% confidence interval [CI]: 2.30–30.10), MSM who had diagnosed with STIs/HIV (AOR 6.71; 95% CI: 4.78–9.28), and MSM who engaged in unprotected insertive anal sex (AOR 1.27; 95% CI: 1.02–1.45) were more likely to have CSP. In contrast, MSM who used condoms consistently during the past six months (AOR = 0.27; 95% CI: 0.08–0.94), MSM who had a regular job (AOR = 0.21; 95% CI: 0.06–0.74), and MSM who initiated sexual activities later in their lives (AOR = 0.08; 95% CI: 0.03–0.25) were less likely to have CSP. Concurrent sexual partnerships are common among MSM in Myanmar. Findings suggest that interventions should focus on MSM who diagnosed with STIs/HIV, do not have regular jobs, and initiated their sexual activities at an early age.
