摘要
目的了解陕西男男性行为者(MSM)中人类免疫缺陷病毒(HIV)感染状况及相关高危行为,为艾滋病(AIDS)疫情估计和预测提供相关信息,为评估AIDS防治工作及该人群预防策略提供科学依据。方法 2007—2011年对陕西MSM进行重复横断面调查检测,对监测结果进行流行病学分析。结果共监测1 856例。未婚者占57.5%～81.0%,流动人口占38.8%～52.3%。监测对象在近6个月内有过同性肛交性行为的占77.0%～99.5%,近6个月内肛交从不用安全套的占3.0%～13.5%,近6个月内有同性商业性行为的占2.5%～17.3%。艾滋病知识知晓率为63.8%～88.3%。最近1 a内接受过同伴教育的占20.8%～56.3%。5 a HIV抗体阳性者检出率分别为3.1%、3.3%、3.8%、8.0%和5.5%,经χ2检验,差异有统计学意义(χ2=29.3,P<0.01)。2009年后HIV-1新发感染率分别为4.8%、3.7%和4.4%。梅毒阳性检出率为3.8%～15.3%。丙型肝炎(HCV)抗体阳性检出率为0～1.5%。二元logistic回归分析显示未婚、同性无保护性肛交、梅毒阳性是感染HIV的危险因素。结论陕西MSM中多种HIV传播的危险因素并存,且AIDS流行加重,有向普通人群蔓延扩散的潜在危险。针对该人群的健康教育和有效干预措施的力度及覆盖面应进一步加大。
[ Objective ] To understand epidemic situation of HIV/AIDS and related high-risk behavior among MSM in Shaanxi Prov-ince, to estimate and predict the AIDS epidemic trends in MSM, and provide scientific evidence for estimating AIDS control and de- veloping intervention strategies. [ Methods ] Repeated cross-sectional survey was performed on MSM in Shanxi Province from 2007-2011. The results were epidemiologieally analyzed. [ Results] A total of 1 856 MSM were surveyed. 57.5%-81.0% of MSM were unmarried, 38. 8%-52.3% were immigrants. In the last 6 months, 77.0%-99. 5% of MSM had anal homo-sex and 3.0%-13.5% of MSM did not use condom during anal homo-sex and 2.5%-17.3% of MSM had commercial homo-sex. The awareness of AIDS related knowledge was 63.8% -88.3%. 20.8%-56.3% had received peer education in the last year. The HIV infection rate from 2007-2011 was 3. 1% , 3. 3% , 3. 8% , 8. 0% , 5. 5% , respectively. Statistical significance was observed （ X^2 =29.3 ,P 〈0. 01 ）. HIV-1 BED infection rate from 2009 to 2011 was 4.8%, 3.7% ,4.4% ,respectively. The syphilis infection rate was 3.8%-15.3%. The HCV infection rate was 0-1.5%. Binary logistic regression analysis showed that high risk factors to HIV infection were unmarried and anal homo-sex and syphilis infection. [ Conclusion ] There are many risk factors involved in the spread of HIV, AIDS epidemic has been aggravated, with potential risk of from MSM to general population in Shaanxi Province. It is necessary to reinforce health education and effective intervention among MSM group.
