目的 了解广东省不同地区吸毒者感染艾滋病病毒 (HIV)的相关危险行为因素 ,以及HIV、丙型肝炎病毒 (HCV)的流行状况。方法 选取 3个市的戒毒所内戒毒者和社区吸毒者进行面对面问卷调查 ,并采集静脉血5ml进行抗 HIV、抗 HCV检测。结果 共调查 6 5 5名吸毒者 ,3个市抗 HIV阳性率分别为 4 0 4 %、2 6 9%和17 6 % (χ2 =2 7 5 4 ,P<0 0 5 ) ;最近 1个月 3个市内吸毒者静脉吸毒 (IDU)的分别为 98 7%、98 7%和 98 4 % ;共用针具的分别为 6 2 8%、33 5 %和 6 8 7% (χ2 =4 5 83,P <0 0 5 ) ;吸毒者首次静脉注射毒品的平均年龄为 2 4 8岁 ,由口吸转为注射毒品的平均年限为 2 7年 ;3个市吸毒者与临时性伙伴的安全套使用率分别为 9 5 %、2 2 6 %和 2 8 6 %。结论 3个市静脉吸毒、共用针具现象普遍 ,共用频率高 ,安全套使用率低 ,但 3个市吸毒者的HIV相关危险行为具有一定差别 ,需进一步研究其潜在的社会背景。
Objective To understand the risk factors of HIV infection among drug users in different areas of Guangdong Province and the prevalence of HIV and hepatitis C virus (HCV). Methods Three drug addicts in drug addicts in three cities were interviewed by face-to-face questionnaires, and 5ml of venous blood was collected for anti-HIV and anti-HCV tests. Results A total of 655 drug addicts were investigated. The positive rates of anti-HIV in the three cities were 40.4%, 26.9% and 17.6%, respectively (χ2 = 2754, P <0 05) Month drug users were 98.7%, 98.7% and 98.4% respectively in the three cities. The share of shared needles was 62.8%, 33.5% and 68.7% respectively (χ2 = 4 5 83, P <0 05). The average age of first drug users was 248 years old. The average life span of the drug from mouth-to-mouth to injection was 27 years. The average number of drug users in the three cities with temporary partners Condom use rates were 95%, 226% and 286% respectively. Conclusions The three intravenous drug use and needle sharing are common, with high sharing frequency and low condom use rate. However, there are some differences in HIV-related risk behaviors between the three city drug users and their potential social background needs to be further studied.
