辽宁省2010—2013年吸毒人群艾滋病哨点监测结果分析

Sentinel surveillance on prevalence HIV/AIDS among drug users in Liaoning province,2010-2013

目的了解辽宁省吸毒人群的行为特征和艾滋病病毒(HIV)感染情况,为预防和控制艾滋病提供科学依据。方法收集辽宁省2010—2013年5个国家级吸毒人群艾滋病哨点监测数据进行统计分析。结果辽宁省5个监测哨点2010—2013年分别监测吸毒人群1 664、1 656、1 939和2 009人,HIV阳性检出率分别为0.1%、0.4%、0.1%和0.1%;丙肝病毒阳性检出率分别为19.9%、14.8%、10.2%和7.6%,呈逐年下降趋势(χ2趋势=140.1,P<0.05);艾滋病知识知晓率分别为76.5%、82.4%、83.2%和86.3%,注射吸毒比例分别为40.1%、31.8%、26.7%和22.8%,最近1年商业性行为坚持使用安全套的比例分别为31.2%、33.3%、38.8%和51.7%,艾滋病知识知晓率、最近1年商业性行为坚持使用安全套的比例均呈逐年上升趋势,注射吸毒比例呈逐年下降趋势(均P<0.05)。结论辽宁省2010—2013年吸毒人群HIV阳性检出率保持在较低水平,丙肝病毒阳性检出率较高,高危行为依然存在,继续有效深入地进行干预是今后工作的重点。

Objective To examine human immunodeficiency virus （HIV）prevalence and behavioral characteristics among drug users （DUs）, and to provide evidences for AIDS prevention and control. Methods Data on sentinel surveillance for HIV/AIDS among DUs from 2010 through 2013 were collected from 5 monitoring points in Liaoning province and analyzed with SPSS 19. 0. Results From 2010 to 2013 ,the number of DUs recruited by the sentinel surveillance was 1 664,1 656,1 939, and 2 009 ,respectively. Among the DUs surveyed, the annual HIV positive rate was 0. 1% ,0.4%, 0. 1% , and 0. 1% and the annual hepatitis C virus （ HCV ） positive rate was 19. 9 %, 14. 8 %, 10. 2 % , and 7.6 %, with a significant decreasing trend （ P 〈 0. 05 ）. For the 4 years among the DUs, the knowledge rate of AIDS was 76. 5%, 82.4% ,83.2% ,and 86. 3% and the consistent condom use rate in commercial sex was 31.2%, 33.3%, 38.8%, and 51.7 % , respectively, and both the rates showed an increasing trend （P 〈 0. 05 for all） ;in addition, the prevalence of injection drug use also showed a decreasing trend （ P 〈 0. 05 ）, with the yearly rate of 40. 1%, 31.8 %, 26. 7 %, and 22. 8 %, respectively. Conclusion The HIV positive rates among DUs in Liaoning province maintained at a low level, but the HCV positive rates was at a high level from 2010 to 2013, suggesting effective intervention on HIV/AIDS high risk behaviors needs to be promoted among DUs in the area.
