2010-2011年天津市VCT点求询者及HIV检出情况分析

Analysis of VCT clients and HIV/AIDS cases detected at VCT sites in Tianjin from 2010 to 2011

目的通过分析天津市2010年和2011年经自愿咨询检测(VCT)点检出的艾滋病病毒(HIV)感染者的流行病学情况,为政府决策提供帮助。方法收集天津市2010年和2011年各VCT点求询者的个案信息,以及通过VCT点上报的所有HIV感染者/艾滋病(AIDS)病人的个案信息,进行流行病学分析。结果 2010年和2011年,天津市各VCT点接受咨询检测人群的HIV检出率分别为0.46%(34/7 472)和0.55%(62/11 367)。求询者男性多于女性,且男性求询者的HIV检出率高于女性;年龄分布以20～39岁年龄组人数居多。有男男性行为史、注射吸毒史、配偶/固定性伴阳性史、母亲阳性史的人群均为HIV检出率高的人群,其中有男男性行为史的求询者中HIV检出率最高为3.34%(59/1 767)。2010年经VCT点发现的HIV/AIDS病人的CD4T淋巴细胞数的中位数为420.50个/μL,2011年为448.00个/μL。结论 VCT点是天津市发现HIV/AIDS病人的重要窗口,应在男男性行为人群、注射吸毒者、HIV/AIDS病人配偶及固定性伴中加强VCT的宣传干预,以提高上述人群高危行为后的HIV咨询检测意识。

Objective To analyze epidemiological features of human immunodeficiency virus/acquired immunode- ficiency syndrome （HIV/AIDS） cases among HIV voluntary counseling and testing （VCT） clients detected at Tian- jin VCT sites from 2010 to 2011, so as to provide supporting evidence for government＇s decision-making. Method Information on individual clients was collected from different VCT sites and epidemiological analysis was conducted among HIV/AIDS cases reported by VCT sites in Tianjin in 2010 and 2011. Results The detection rates of HIV/ AIDS among VCT clients in Tianjin in respective years of 2010 and 2011 were 0.46% （34/7 472） and 0.55%（62/ 11 367）. Males were more than females; the detection rate of HIV/AIDS in male clients was higher than in female ones; the main age distribution was 20-39 years. High detection rate of HIV/AIDS was identified in the popula- tions of MSM, injection drug users, HIV positive spouse/regular sex partners, and HIV positive mothers, of whom those with a history of male homosexual behaviors had the highest rate, about 3.34% （59/1767）. The median value of CD4 counts among the HIV/AIDS ＇cases detected at VCT sites was 420.50/μL in 2010 and 448.00/μL in 2011. Conclusion VCT site is an important window for identifying HIV/AIDS cases in Tianjin. It is necessary to strengthen VCT interventions among MSM, injection drug users, and HIV/AIDS positive spouse/regular sex part- ners, so that they may raise their awareness of VCT after having high-risk behaviors.
