ABSTRACT

Objective To understand the prevalence of synthetic drug use among man who have sex with man (MSM) in Nanjing and the associated factors. Methods MSM were recruited by snow-ball sampling, peer recommendation and network recruitment. Multivariate logistic regression analysis was performed to evaluate the correlated factors of recreational drug use. Results 29.6% of the 876 MSM ever used recreational drugs. The prevalence of HIV and syphilis infections were 9.5% and 9.0% respectively. After controlling the influence of correlated factors, recreational drug use was correlated with unprotected anal intercourse in the past 6 months(OR=1.83, 95% CI 1.35-2.47, P<0.001), multiple male sex partnership in the past 6 months(OR=2.25, 95% CI 1.65-3.05, P<0.001), higher HIV prevalence (OR=1.95, 95% CI 1.21-3.17, P=0.007) and higher syphilis prevalence(OR=1.71, 95% CI 1.02-2.84, P=0.040). Multivariate Logistic analysis showed that demographic and behavioral factors associated with recreational drug use including less than 30 years old (OR=1.50, 95% CI 1.07-2.11, P=0.020), self-identified as homosexual orientation (OR=1.65, 95% CI 1.16-2.34, P=0.005), seeking male partners mainly via the internet(OR=1.58, 95% CI 1.07-2.35, P=0.022), higher monthly income(OR=1.57, 95% CI 1.13-2.17, P=0.007), receptive sexual role(OR=1.55, 95% CI 1.04-2.32, P=0.033). Conclusions MSM has a high prevalence of recreational drug use in Nanjing, which was positively correlated with HIV/syphilis infection and high risk behaviors. Intervention efforts should be devoted to reduce and combat drug use among MSM.
