This study investigated the sexual risk behaviors among injection drug users. (IDUs) in order to inform the development of sexual risk reduction interventions for IDUs.
A cross-sectional survey of IDUs (n=141) was conducted in an in-patient detoxification treatment center in Shanghai, China, to collect information on demographics; drug use history; sexual risk behavior; HIV/AIDS knowledge, attitudes, and other psychosocial variables; and HIV, HBV, and HCV seroprevalence. Factors associated with HIV sexual risk behaviors and HBV and/or HCV infection were analyzed.
Sexual risk behaviors among IDUs were common: the majority (77%) of the participants had not used a condon consistently in the previous 3 months, 25.5% had multiple partners, 48.2% had IDU partners, and 75.9% did not know their partner's HIV status. IDUs who were married (OR=4.83, p<0.05) or did not intent to use condoms in the future (OR=0.21, p<0.05) were more likely to have unprotected sex. The prevalence of HBV and HCV infection was 31.9% and 51.8%, respectively, but no one tested positive for HIV.IDUs with an injection history of 3 years or more (OR=5.86, p<0.05) and with an overdose history (OR=3.21, p<0.05) were more likely to be infected with HBV and/or HCV.
Sexual risk behaviors among IDUs in Shanghai are common, and many IDUs are vulnerable for transmission of disease. Prevention efforts with IDUs should address sexual risk behaviors in addition to needle-sharing behaviors.
本研究调查了注射吸毒者中的性风险行为，以便为制定针对注射吸毒者的性风险降低干预措施提供依据。
在中国上海的一家住院戒毒治疗中心对141名注射吸毒者进行了横断面调查，以收集有关人口统计学、吸毒史、性风险行为、艾滋病毒/艾滋病知识、态度及其他社会心理变量，以及艾滋病毒、乙肝病毒和丙肝病毒血清流行率的信息。分析了与艾滋病毒性风险行为以及乙肝病毒和/或丙肝病毒感染相关的因素。
注射吸毒者中的性风险行为很常见：大多数（77%）参与者在过去3个月中未始终坚持使用避孕套，25.5%有多个性伴侣，48.2%有注射吸毒者性伴侣，75.9%不知道其性伴侣的艾滋病毒感染状况。已婚的注射吸毒者（比值比=4.83，p<0.05）或未来不打算使用避孕套的人（比值比=0.21，p<0.05）更有可能进行无保护性行为。乙肝病毒和丙肝病毒感染率分别为31.9%和51.8%，但无人艾滋病毒检测呈阳性。注射史达3年或更长时间的注射吸毒者（比值比=5.86，p<0.05）和有过量用药史的人（比值比=3.21，p<0.05）更有可能感染乙肝病毒和/或丙肝病毒。
上海注射吸毒者中的性风险行为很常见，许多注射吸毒者易感染疾病。对注射吸毒者的预防工作除了应针对共用针头行为外，还应解决性风险行为问题。
