目的了解乌鲁木齐市静脉吸毒人群艾滋病病毒(HIV)感染情况。方法于2004年9~10月,调查戒毒所等机构内静脉吸毒人群的社会人口学、静脉吸毒和性行为方式,并采集血样检测HIV和梅毒抗体。结果在调查的静脉吸毒者509人中,HIV感染率为37.3%(190人)。多因素logistic回归模型分析结果显示,维族(OR 7.91,95%CI 4.92~12.72)、近3个月内共用注射器具静脉吸毒5次及以上(OR 2.61,95%CI 1.48~4.60)和静脉吸毒5年以上(OR 1.64,95%CI 1.09~2.48)与HIV感染关系有统计学意义。结论乌鲁木齐市静脉吸毒人群HIV感染率高,高危行为普遍,需采取有效的措施来控制HIV的传播流行。
Objective To understand the HIV infection among intravenous drug users in Urumqi. Methods From September to October 2004, the socio-demographic, intravenous drug use and sexual behavior patterns of intravenous drug users in institutions such as drug treatment centers were investigated. Blood samples were collected for the detection of HIV and syphilis antibodies. Results Among the 509 intravenous drug users surveyed, the HIV infection rate was 37.3% (190). Multivariate logistic regression model analysis showed that Uygur (OR 7.91, 95% CI 4.92-12.72) shared intravenous drug use 5 times and above (OR 2.61, 95% CI 1.48-4.60) and intravenous drug use in the past 3 months More than 5 years (OR 1.64, 95% CI 1.09 ~ 2.48) had a statistically significant relationship with HIV infection. Conclusion The prevalence of HIV infection and high-risk behaviors among intravenous drug users in Urumqi are generally high, and effective measures should be taken to control the HIV transmission.
