This study examines the association between drug and sexual HIV risk behaviours and knowledge of HIV serostatus among a sample of injection drug users, recruited into the 2009 National HIV Behavioral Surveillance project. We calculated prevalence ratios and associated 95% confidence intervals of reporting a given risk behaviour comparing injection drug users unaware of their serostatus and HIV-negative to HIV-positive injection drug users. Of 523 participants, 21% were unaware of their HIV serostatus. The three groups were not different from each other in terms of drug-use behaviours; however, injection drug users unaware of their HIV serostatus were 33% more likely to report having more than three sexual partners in the past 12 months and 45% more likely to report having unprotected sex compared to HIV-positive injection drug users. We observed markedly higher prevalence of sexual risk behaviours among injection drug users unaware of their serostatus, but drug-use risk behaviours were similar across the groups.
本研究调查了参与2009年全国艾滋病行为监测项目的一组注射吸毒者中，药物使用及艾滋病病毒（HIV）性风险行为与HIV血清学状态知晓情况之间的关联。我们计算了报告特定风险行为的患病率比值及相关的95%置信区间，比较了不知晓自身血清学状态且HIV阴性的注射吸毒者与HIV阳性的注射吸毒者。在523名参与者中，21%不知晓自身的HIV血清学状态。三组在药物使用行为方面无差异；然而，与HIV阳性的注射吸毒者相比，不知晓自身HIV血清学状态的注射吸毒者在过去12个月内报告有三个以上性伴侣的可能性高33%，报告有不安全性行为的可能性高45%。我们观察到不知晓自身血清学状态的注射吸毒者中性风险行为的患病率明显更高，但各组间药物使用风险行为相似。
