Studies tracking trends in HIV prevalence and risk behavior among men who have sex with men (MSM) in China are rare. We report on 3 consecutive cross-sectional surveys measuring the prevalence of HIV, other infectious diseases, and related risk behavior among MSM in Beijing in 2004, 2005, and 2006.
We applied respondent-driven sampling (RDS) to recruit MSM for a structured face-to-face interview on demographic characteristics and HIV risk-related behavior. Blood specimens were drawn for HIV syphilis, hepatitis B virus, and hepatitis C virus (HCV) testing.
A total of 325 MSM participated in 2004, 427 in 2005, and 540 in 2006. HIV prevalence was 0.4% (95% confidence interval [CI]: 0.1 to 0.8) in 2004, 4.6% (95% CI: 2.2 to 7.6) in 2005, and 5.8% (95% CI: 3.4 to 8.5) in 2006. This apparent rise was accompanied by an increase in syphilis and self-reported history of sexually transmitted diseases (STDs), high prevalence of multiple sex partners, and low consistent condom use. HCV prevalence also increased, from 0.4% (95% CI: 0.1 to 0.8) in 2004 to 5.2% (95% CI: 2.3 to 8.2) in 2006.
We detected a possible rising prevalence of HIV and related risk behavior among MSM in Beijing using RDS in each of 3 consecutive years. Practical measures, including MSM-friendly HIV testing, STD services, and health provider education, are urgently needed to stop the further spread of HIV in this population.
在中国,追踪男男性行为者(MSM)中艾滋病毒流行趋势和风险行为的研究很少。我们报告了2004年、2005年和2006年在北京对MSM进行的连续3次横断面调查,这些调查测量了艾滋病毒、其他传染病及相关风险行为的流行情况。
我们采用应答驱动抽样(RDS)招募MSM,对其进行关于人口统计学特征和艾滋病毒风险相关行为的结构化面对面访谈。采集血样进行艾滋病毒、梅毒、乙型肝炎病毒和丙型肝炎病毒(HCV)检测。
2004年共有325名MSM参与,2005年为427名,2006年为540名。2004年艾滋病毒流行率为0.4%(95%置信区间[CI]:0.1至0.8),2005年为4.6%(95%CI:2.2至7.6),2006年为5.8%(95%CI:3.4至8.5)。这种明显的上升伴随着梅毒和自我报告的性传播疾病(STD)病史的增加、多个性伴侣的高流行率以及避孕套的低持续使用率。HCV流行率也有所上升,从2004年的0.4%(95%CI:0.1至0.8)升至2006年的5.2%(95%CI:2.3至8.2)。
我们连续3年在北京使用RDS检测到MSM中艾滋病毒及相关风险行为的流行率可能在上升。迫切需要采取切实可行的措施,包括对MSM友好的艾滋病毒检测、STD服务以及对医疗服务提供者的教育,以阻止艾滋病毒在该人群中的进一步传播。
