越南籍跨境暗娼艾滋病性病感染及危险因素调查

目的 了解越南籍跨境暗娼人群艾滋病(acquired immunodeficiency syndrome, AIDS)性病(sexually transmitted diseases,STD)感染情况,高危行为特征及危险因素,为制定有针对性的预防控制措施提供依据。 方法 采用"滚雪球、同伴推动"等方法,由经培训懂双语的外展人员对越南籍跨境暗娼人群进行面对面问卷调查,调查内容包括人口学特征、艾滋病知识、高危行为、安全套使用情况等,并采集静脉血3～5 ml进行艾滋病病毒(human immunodeficiency virus,HIV)、梅毒抗体检测,应用SPSS 19.0 软件分析其中HIV、梅毒感染状况及探讨影响越南籍跨境暗娼人群商业性行为不使用安全套的可能因素。 结果 92例调查对象中,未发现HIV抗体阳性者,梅毒抗体阳性1例,阳性率为1.09%。调查对象均存在有多国商业性伴情况,每日接客数量为3个及以上者高达60.87%,最近1次和最近1个月商业性行为每次都使用安全套的比例分别为80.44%和68.48%;有54.35%的调查对象,在最近1个月内与固定性伴(熟客)发生过性关系, 最近1次和最近1个月每次性行为均无人使用安全套。通过多因素logistic回归分析显示,高档/中档服务场所(OR=15.021, 95%CI:2.820～80.023)是越南跨境暗娼商业性行为使用安全套的保护因素,首次性服务年龄≥30岁(OR=0.165, 95%CI:0.042～0.651)、每日接客数量≥3个(OR=0.129, 95%CI:0.023～0.737)是越南跨境暗娼商业性行为使用安全套的主要危险因素。 结论 越南籍跨境暗娼人群普遍存在多国商业性伴情况,低档服务场所、每日接客数量较多、高年龄组的暗娼安全套使用频率较低。提示在今后干预工作中,应充分考虑不同档次高危娱乐场所和高危性行为特征,开展有针对性的综合干预工作。

HIV/AIDS and sexually transmitted disease infections and their risk factorsamong Vietnamese cross-border female sex workers

Objective To investigate the situation of HIV (human immunodeficiency virus) / acquired immunodeficiency syndrome (AIDS) and sexually transmitted diseases (STDs) infections, the features of high-risk behavior and risk factors among Vietnamese cross-border female sex workers, and to provide a basis for formulating targeted prevention and control measures. Methods The methods of incentivized snowball sampling and respondent driven sampling were used in this study. A face-to-face questionnaire survey of Vietnamese cross-border female sex workers was conducted by the trained bilingual outreach workers, and the contents of investigation included demographic characteristics, HIV/AIDS-related knowledge, high-risk behavior and condom use. 3-5 ml venous blood was collected for testing the antibodies against HIV and syphilis. SPSS 19.0 software was employed to analyze the infection rates of HIV and syphilis as well as the possible factors influencing commercial sex transaction without condom use among Vietnamese cross-border female sex workers. Results No HIV antibody positive case was detected among 92 respondents surveyed, but one case with positive syphilis antibody was detected, with the positive rate being 1.09%. All the female sex workers had multinational commercial sexual partners, and 60.87% of them received ≥3 male clients daily. The proportions of condom use in the last episode and the last month of commercial sex were 80.44% and 68.48% respectively. 54.35% of the female sex workers had sexual intercourse with fixed sex partners (old clients) within the last month, but did not use condoms in the last episode of commercial sex and during each sexual intercourse in the last month. Multivariate logistic regression analysis showed that high- and intermediate-grade service places (OR=15.021, 95%CI:2.82-80.023) was a protective factor for condom use, while the age of first sex service ≥ 30 years (OR=0.165, 95%CI:0.042-0.651) and daily receiving≥3 male clients (OR=0.129, 95%CI:0.023-0.737) were the main risk factors for condom use. Conclusions It is prevailing for Vietnamese cross-border female sex workers to have multinational commercial sex partners, and the frequency of condom use in the female sex workers from low-grade service places, receiving more male clients within one day and from older-age group is low. Targeted comprehensive intervention should be conducted based on full consideration of different grades of high-risk entertainment places and characteristics of high-risk sexual behavior.
