广东省2009年高危人群HIV哨点综合监测结果分析

Surveillance of AIDS high-risk people in Guangdong province,2009

目的通过对吸毒人群(DUs)、暗娼(FCSWs)、男男性行为者(MSMs)和男性性病门诊就诊者(MSTDs)四类艾滋病(AIDS)主要高危人群的综合监测,了解他们的艾滋病病毒(HIV)流行情况及其高危行为。方法按照艾滋病行为和血清学监测方案的操作程序及调查方法对四类人群进行行为及血清学监测。结果 13620例DUs、5309例FCSWs、970例MSMs、4273例MSTDs的HIV阳性率分别为3.7%、0.2%、4.7%、0.3%,梅毒阳性率分别为4.5%、3.1%、12.0%、6.5%,丙肝阳性率分别为34.5%、0.6%、0.5%、0.7%,注射吸毒率分别为68.1%、0.7%、0.3%、3.7%,商业性交率分别为23.3%、100.0%、17.2%、41.4%,艾滋病知识知晓率分别为73.4%、69.4%、82.9%、66.4%,干预覆盖率分别为40.8%、47.0%、74.7%、31.5%。结论四类高危人群中均检出HIV感染者,感染率以MSMs最高,其次为DUs,FCSWs感染率最低,各高危人群均存在感染HIV的诸多危险因素,应加大综合干预力度。

Objective To determine the epidemiologic characteristics and the risk factors of HIV infection in the drug users,female commercial sex workers,homosexual male subjects and male STD patients.Methods Serum samples from 13 620 drug users,5 309 female commercial sex workers,970 homosexual male subjects and 4 273 male STD patients were analyzed according to the standard protocols.Results The positive rate of HIV infection in the drug users,female commercial sex workers,homosexual male subjects and male STD patients was 3.7%,0.2%,4.7% and 0.3%,respectively.The positive rate of syphilis in these 4 groups of patients was in the order of 4.5%,3.1%,12.0% and 6.5%;the positive rate of hepatitis C virus infection was in the order of 34.5%,0.6%,0.5% and 0.7%.The percentage of drug abuse patients in these 4 groups was in the order of 68.1%,0.7%,0.3% and 3.7%;and the percentage subjects with commercial sexual behavior in these 4 groups was 23.3%,100%,17.2% and 41.4%.The percentage of subjects had knowledge on HIV/AIDS in these 4 groups was 73.4%,69.4%,82.9% and 66.4%.The intervention coverage rate was 40.8%,47.0%,74.7% and 31.5%.Conclusion AIDS patients were identified in these four high-risk groups.The highest rate of infection was found in male STD patients,followed by the drug users.The lowest rate of infection was in the group of female commercial sex workers.The program of AIDS surveillance should be strengthened.
