To investigate the prevalence of HIV infection/STD and related factors in Vietnamese female sex workers (FSWs). 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 (2) test was applied for HIV infection/STD and drug use trend analysis. Multivariate logistic regression model was used to identify the related factors. 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 ((2)=4.823, =0.028). By logistic regression analysis, the related factors for HIV infection in Vietnamese FSWs were being amphetamine type stimulants (ATS) positive (=10.18, 95: 4.33-23.92) and being HSV-2 positive (=2.89, 95: 1.09-7.88); Age (=1.88, 95: 1.32-2.61), no-paid sexual partner (=1.59, 95: 1.26-2.01) and being ATS positive (=2.48, 95: 1.10-5.57) were related factors for HSV-2 infection. 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.
调查越南女性性工作者（FSWs）中艾滋病毒感染/性传播疾病（STD）的流行情况及相关因素。于2014年6月、2014年12月、2015年5月和2015年11月在云南省与越南接壤的河口县进行了连续的横断面调查。采用方便抽样的方法选取了1058名年龄大于16岁的越南女性性工作者。通过问卷调查收集她们的人口统计学信息、性行为和吸毒情况。采集血清和尿液样本进行艾滋病毒感染/性传播疾病检测及吸毒检测。应用趋势（2）检验对艾滋病毒感染/性传播疾病和吸毒趋势进行分析。使用多变量逻辑回归模型确定相关因素。连续横断面调查表明，越南女性性工作者中艾滋病毒感染率分别为3.20（7/219）、2.04（5/245）、1.89（5/265）和1.82（6/329）；单纯疱疹病毒2型（HSV-2）阳性率分别为57.08（125/219）、58.37（143/245）、38.11（101/265）和51.06（168/329）。此外，梅毒患病率分别为0.91、1.51、0.75和1.22。HSV-2感染率呈下降趋势（（2）=4.823，=0.028）。通过逻辑回归分析，越南女性性工作者中艾滋病毒感染的相关因素为苯丙胺类兴奋剂（ATS）阳性（=10.18，95%可信区间：4.33 - 23.92）和HSV-2阳性（=2.89，95%可信区间：1.09 - 7.88）；年龄（=1.88，95%可信区间：1.32 - 2.61）、无酬性伴侣（=1.59，95%可信区间：1.26 - 2.01）和ATS阳性（=2.48，95%可信区间：1.10 - 5.57）是HSV-2感染的相关因素。与以往研究结果相比，越南女性性工作者中艾滋病毒感染率有所下降，但HSV-2感染率仍然较高。ATS使用与艾滋病毒感染/性传播疾病之间的关联表明，有必要加强对越南女性性工作者的艾滋病干预，包括控制新型毒品和性传播。
