目的了解清远市2007年吸毒人群HIV、梅毒感染状况及危险行为的特征,为制定艾滋病预防控制策略提供科学依据。方法2007年6—12月对清远市3家强制戒毒所的所有吸毒者进行行为学调查,并采集血样进行HIV、梅毒抗体检测。结果共调查1073名吸毒者,吸毒者以20~39岁男性为主,吸毒方式以静脉注射为主,占75.58%,其中共用针具占53.21%;曾有性乱经历的人数占53.22%(571/1073);安全套每次使用的人数占11.56%(66/571),偶尔使用的人数占22.24%(127/571),从来不使用的人数占66.20%(378/571)。共检测3家戒毒所1073名吸毒者血清样本,HIV抗体阳性率为3.08%(33/1073),梅毒抗体阳性率为9.97%(107/1073),其中同时感染HIV和梅毒的2例,感染率为0.19%。结论清远市吸毒人群HIV和梅毒感染虽属低流行,但感染HIV的危险因素普遍存在,应尽快采取有效措施防止HIV在该人群中传播以及该人群向其他高危人群和一般人群传播。
Objective To understand the characteristics of HIV and syphilis infection among dangerous drug users in Qingyuan City in 2007 and to provide a scientific basis for the development of AIDS prevention and control strategies. Methods From June to December 2007, behavioral investigation was conducted on all drug users from 3 compulsory drug treatment centers in Qingyuan City. Blood samples were collected for HIV and syphilis antibody testing. Results A total of 1073 drug addicts were investigated. Drug users were mainly male aged 20-39. Drug abuse was mainly by intravenous injection, accounting for 75.58%, of which 53.21% were shared needles; 53.22% had sexual experience 571/1073). Condom use accounted for 11.56% (66/571) per use, occasionally 22.24% (127/571) and never used 66.20% (378/571). A total of 1073 drug addicts from 3 drug addicts were tested for serological tests. The positive rate of HIV antibody was 3.08% (33/1073), the positive rate of syphilis antibody was 9.97% (107/1073), of which 2 were infected with HIV and syphilis at the same time. The rate was 0.19%. Conclusion Although HIV and syphilis infections among drug users in Qingyuan City are low-prevalence, the risk factors for HIV infection are prevalent. Effective measures should be taken to prevent the spread of HIV in this population as soon as possible and to other high-risk groups and the general population.
