目的了解2010年乌鲁木齐市吸毒人群人类免疫缺陷病毒(HIV)感染率及相关行为特征。方法查询公安部门资料结合滚雪球办法招募吸毒人员,进行面对面的问卷调查,采集血样进行HIV、丙型肝炎病毒(HCV)和梅毒抗体检测。结果本组共调查和采样吸毒人员1 516名,检出HIV、HCV和梅毒的感染者分别占20.38%(309/1 516)、36.02%(546/1 516)和2.24%(34/1 516)。高危行为分析吸毒者中男性(OR:0.62;95%CI:0.40～0.96)、维吾尔族(OR:0.45;95%CI:0.34～0.60)、未接受过预防艾滋病服务者(OR:2.32;95%CI:1.65～3.26)共用注射器的比例高;安全套的使用上维吾尔族(χ2=11.98,P=0.0005),艾滋病基本知识得分低者(χ2=4.85,P=0.0275)安全套的使用率低。结论乌鲁木齐市吸毒人群HIV流行形势严峻,如何采取行之有效的干预措施降低高危行为势在必行。
Objective To understand the prevalence and related behavioral characteristics of human immunodeficiency virus (HIV) among drug users in Urumqi in 2010. Methods The public security department information and snowball method were used to inquire about drug addicts. Face-to-face questionnaires were conducted to collect blood samples for detection of HIV, hepatitis C virus (HCV) and syphilis antibody. Results A total of 1 516 drug abusers were surveyed and sampled. Among them, 20.38% (309/1 516), 36.02% (546/1 516) and 2.24% (34/1 516) were detected for HIV, HCV and syphilis, respectively ). High-risk behavior analysis Among male drug users (OR: 0.62; 95% CI: 0.40-0.96), Uyghur (OR: 0.45; 95% CI: 0.34-0.60) % CI: 1.65-3.26). The condom use rate was lower in the Uygur nationality (χ2 = 11.98, P = 0.0005) and in the low AIDS basic knowledge score (χ2 = 4.85, P = 0.0275). Conclusion HIV prevalence among drug users in Urumqi is very serious. It is imperative to take effective interventions to reduce high-risk behaviors.
