摘　　要：目的研究注射吸毒者作为桥梁人群通过性行为传播STI(性传播疾病)和HIV(艾滋病病毒)给性伴的现象,探讨桥梁人群和非桥梁人群传播HIV的危险性。方法采用横断面整群抽样方法,面对面进行结构化无个人特征信息的问卷调查。同时采血检测HIV、HCV(丙型肝炎)和梅毒抗体。结果312名吸毒者参加本次研究。确定是桥梁人群的吸毒者154人,占49.4%。在桥梁人群中有83.1%注射过毒品;35%(54人)在过去几个月内与他人共用针头或注射器;87%(134人)在过去1年有1个或更多商业性伙伴。53.5%的女性和8.2%的男性桥梁人群每次和商业性伴发生性行为时使用安全套。3.9%的桥梁人群和4.6%的非桥梁人群与固定性伴每次使用安全套。1名男性桥梁人群检出感染了HIV。58%(90/154)的桥梁人群和46.8%(74/158)的非桥梁人群检出感染丙肝(χ2=4.21,P=0.04)。24名(15.6%)桥梁人群和11名(7%)非桥梁人群检出梅毒阳性(χ2=5.82,P=0.02)。结论吸毒者中的桥梁人群传播STI/HIV的危险度较高。应加强吸毒人群的健康教育和相关行为干预。Objective To document and compare risks for sexually transmitted diseases including sexually transmitted AIDS between a bridge population and a non - bridge population. Methods With to the cross - sectional study, Trained interviewers conducted face - to - face interviews with uniform questionnaires. All the samples were screened by HIV antibody and HCV antibody and syphilis test. Results All of the 312 drug users in the two centers were invited and agreed to participate in the study. A substantial number of drug users were bridgers （49.4% ; N = 154）. Among bridgers, 83.1% injected drugs ; 76.6% （ 118/154） injected drugs two or more times per day ; and 35% （ 54） shared needles or syringes with others in the past month. Among non - bridgers 62% injected drugs ; 48.7% （77/158） injected drugs two or more times per day; and 3.2% （5 ） shared needles or syringes. Eighty - seven percent （ 134） of bridgers and none of nonbridgers reported having one or more commercial sex partners in the past year. More than half （53.5%） female bridgers and only 8.2% （5/61 } of male bridgers used condoms every time or almost every time with their commercial sex partners. Condom use with regular sex partners was extremely low among both bridgers and non - bridgers. Only 3.9% of the bridgers and 4.6% of non - bridgers used condoms every time or almost every time. Only one study participant （ a male bridger） tested positive for HIV infection. Fifty - eight percent （90/154} of bridgers and 46.8% （74/158） of non - bridgers tested positive for HCV （χ^2 = 4. 21 ,P = 0.04）. Twenty -four （ 15.6% ） bridgers and eleven （7% ） non - bridgers tested positive for syphilis （χ^2 = 5. 82, P = 0.02）. Conclusion Intervention should be considered to prevent STI/HIV infection from the drug userscommunity and reduce transmission to the general population.
