目的:了解新疆乌鲁木齐市社区静脉注射吸毒人群艾滋病病毒(HIV)感染情况。方法:于2005年4-6月以社区为基础招募静脉吸毒者,调查其社会人口学、静脉吸毒行为和性行为方式,并采集血样检测HIV和梅毒抗体。结果:调查的401名静脉吸毒者中,HIV感染率为36.4%(146/401),多因素Logistic回归分析结果显示,维族(OR,8.42;95%CI,4.44-15.99)、结婚或同居(OR,2.30;95%CI,1.33-3.97)、累积共用注射吸毒10次及以上(OR,3.10;95%CI,1.81-5.33)、静脉吸毒5年以上(OR,4.10;95%CI,2.47-6.81)与HIV感染关系有统计学意义。结论:该地区静脉吸毒人群HIV感染率高,应针对当地静脉吸毒人群共用注射吸毒行为开展干预来控制HIV的传播和流行。
Objective: To understand the HIV infection among intravenous drug users in community in Urumqi, Xinjiang. METHODS: Community-based drug abusers were recruited from April to June 2005 to investigate their socio-demographic, intravenous and drug use behaviors and sexual behaviors. Blood samples were collected for the detection of HIV and syphilis antibodies. Results: The HIV prevalence of 401 intravenous drug users surveyed was 36.4% (146/401). Multivariate Logistic regression analysis showed that Uygur (OR, 8.42; 95% CI, 4.44-15.99), married or cohabited (OR, 3.10; 95% CI, 1.81-5.33), and intravenous drug use for more than 5 years (OR, 4.10; 95% CI, 2.47; 95% CI, 1.33-3.97) -6.81) had a statistically significant relationship with HIV infection. CONCLUSIONS: HIV prevalence rates among intravenous drug users in this area are high. Interventions should be made to control the spread and prevalence of HIV in response to the sharing of drug abuse among local intravenous drug users.
