摘要目的 了解越南籍暗娼HIV/性传播疾病(STD)感染及其相关因素.方法 分别于2014年6月、12月和2015年5月、11月,在云南省河口县开展连续横断面调查,采用方便抽样方式纳入年龄≥16周岁的越南籍暗娼共1 058人.问卷调查收集越南籍暗娼人口学特征、性行为及吸毒行为等信息;血液和尿液样本检测分析HIV/STD感染及毒品使用.应用趋势x2检验分析越南籍暗娼HIV/STD感染和毒品使用及变化趋势,应用logistic回归分析HIV/STD感染的相关因素.结果 连续横断面调查中,越南籍暗娼的HIV感染率分别为3.20％(7/219)、2.04％(5/245)、1.89％(5/265)和1.82％(6/329);2型单纯疱疹病毒(HSV-2)感染率为57.08％ (125/219)、58.37％(143/245)、38.11％(101/265)和51.06％ (168/329);梅毒感染率为0.91％(2/219)、1.51％ (4/245)、0.75％(2/265)、1.22％(4/329).HSV-2感染率呈现下降趋势(x2=4.823,P=0.028).logistic回归分析结果显示,越南籍暗娼HIV感染的相关因素包括:甲基安非他明(ATS)阳性(OR=10.18,95％CI:4.33～23.92)和HSV-2阳性(OR=2.89,95％CI:1.09 ～ 7.88).年龄(OR=1.88,95％CI:1.32 ～ 2.61)、非付费性伴(OR=1.59,95％CI:1.26 ～ 2.01)及ATS阳性(OR=2.48,95％CI:1.10～5.57)是越南籍暗娼HSV-2感染的相关因素.结论 越南籍暗娟HIV感染率较过去有所下降,HSV-2感染率有下降趋势但仍然较高.ATS使用与HIV/HSV-2感染有关联,应该对越南籍暗娼加强控制新型毒品和性传播疾病的综合性干预措施.

abstractsObjective To investigate the prevalence of HIV infection/STD and related factors in Vietnamese female sex workers (FSWs).Methods Consecutive cross-sectional surveys were conducted in June 2014,December 2014,May 2015 and November 2015 in Hekou,a county bordering Vietnam in Yunnan province.Convenience sampling were adopted to select 1 058 Vietnamese FSWs aged ＞16 years.Questionnaire interview were used to collect the information about their demographics,sexual behaviors and drug use.Serum and urine samples were collected for HIV infection/STD detection and drug use test.Trend x2 test was applied for HIV infection/STD and drug use trend analysis.Multivariate logistic regression model was used to identify the related factors.Results The consecutive cross sectional surveys indicated that the prevalence of HIV infection in Vietnamese FSWs were 3.20％(7/219),2.04％(5/245),1.89％(5/265) and 1.82％(6/329) respectively;the HSV-2 positive rates were 57.08％(125/219),58.37％(143/245),38.11％(101/265) and 51.06％ (168/329) respectively.In addition,the prevalence of syphilis were 0.91％,1.51％,0.75％ and 1.22％ respectively.HSV-2 infection prevalence showed a downward trend (x2=4.823,P=0.028).By logistic regression analysis,the related factors for HIV infection in Vietnamese FSWs were being amphetamine type stimulants (ATS) positive (OR=10.18,95％ CI:4.33-23.92) and being HSV-2 positive (OR=2.89,95％CI:1.09-7.88);Age (OR=1.88,95％CI:1.32-2.61),no-paid sexual partner (OR=1.59,95％CI:1.26-2.01) and being ATS positive (OR=2.48,95％CI:1.10-5.57) were related factors for HSV-2 infection.Conclusions Compared with the results of previous studies,the HIV infection prevalence declined in Vietnamese FSWs,but the HSV-2 infection prevalence was still high.The association between ATS use and HIV infection/STD suggested the necessity of strengthening AIDS intervention in Vietnamese FSWs,including the control of new type drug and sexual transmission.
