Iran is facing unprecedented dual drug use and HIV epidemics. We conducted a cross-sectional survey to obtain HIV prevalence and risk behavior data from injection drug users (IDU) in Tehran. We used respondent-driven sampling (RDS) to recruit IDU through successive waves starting with 24 "seeds," conducted anonymous face-to-face interviews and HIV testing and counseling, and used RDSAT to adjust data. During 44 weeks, 1,726 study referral coupons resulted in 645 (37 %) IDU referrals, of whom 548 (85 %) were enrolled. From those enrolled, 84 % were incarcerated, 47 % employed, 55 % single, 27 % under 30 years of age, and 26 % homeless. The adjusted HIV prevalence was 26.6 % (95 % confidence interval 21.3-32.1), and was higher among certain IDU subgroups (e.g., those who sharing injection paraphernalia). Our estimates of HIV prevalence were higher than some other estimates; however, repeated surveys using similar methodology are needed to monitor the trend of HIV epidemic over time.
伊朗正面临前所未有的双重药物使用和艾滋病流行问题。我们开展了一项横断面调查，以获取德黑兰注射吸毒者（IDU）的艾滋病毒流行率和风险行为数据。我们采用应答者驱动抽样（RDS）方法，从24名“种子”开始，通过连续多轮招募注射吸毒者，进行匿名面对面访谈、艾滋病毒检测和咨询，并使用RDSAT对数据进行调整。在44周内，1726张研究转诊优惠券带来了645名（37%）注射吸毒者转诊，其中548名（85%）被纳入研究。在纳入的人员中，84%被监禁，47%就业，55%单身，27%年龄在30岁以下，26%无家可归。调整后的艾滋病毒流行率为26.6%（95%置信区间21.3 - 32.1），在某些注射吸毒者亚组中更高（例如，那些共用注射器具的人）。我们对艾滋病毒流行率的估计高于其他一些估计；然而，需要使用类似方法进行重复调查，以监测艾滋病毒流行随时间的趋势。
