开远市嫖客人群艾滋病相关知识、高危行为和STDs感染状况分析

目的了解开远市嫖客人群艾滋病(acquired immunodeficiency syndrome, AIDS)相关知识和高危行为状况,以及感染人类免疫缺陷病毒(human immunodeficiency virus, HIV)、梅毒、生殖器单纯疱疹病毒(herpes simplex virus type 2, HSV-2)状况,分析HSV-2感染相关因素,为制定预防措施提供依据。方法采用"外展人员招募"与"滚雪球"方式招募对象,问卷调查并采集血液和尿液进行相应实验室检查。结果 98.22%的嫖客知晓艾滋病知识;9.33%曾使用过毒品;14.67%在最近一次商业性行为时未使用安全套;62.22%曾有过非婚性伴,在过去一年与非婚性伴有性行为的嫖客中,59.55%未坚持使用安全套。嫖客中HIV/梅毒/HSV-2的总体感染率为18.22%,其中HIV、梅毒、HSV-2的感染率分别为3.11%、1.33%、16.44%。年龄较大者HSV-2感染率较高AOR=1.044,95%CI:1.016～1.073,P=0.002],最近一次商业性行为中未使用安全套者HSV-2感染率较高AOR=3.125,95%CI:1.229～7.945,P=0.017]。结论开远市嫖客人群艾滋病知识知晓率高,但仍存在高危行为,有较高的HIV和其它性传播疾病感染率,需采取针对性干预措施,提高该人群感染性传播疾病的风险意识,促进他们在商业和非婚性行为中坚持使用安全套。

Analysis on AIDS related knowledge,high-risk behaviors and STDs infection status of whoremasters in Kaiyuan City,Yunnan Province

  Objective  To understand the awareness of AIDS related knowledge, high risk behaviors, the infection status of HIV, syphilis and HSV-2, and to explore the associated factors with HSV-2 infection among whoremasters in Kaiyuan City, so as to provide scientific evidence for targeted intervention to prevent and control HIV and other STDs.  Methods  A self-designed questionnaire survey was conducted among whoremasters recruited through outreach activities and snowball sampling. The blood and urine were also collected for corresponding laboratory examination.  Results  Among the whoremasters, 98.22% had a high awareness of AIDS related knowledge, 9.33% once used drugs, and 14.67% did not use a condom during the latest commercial sex. 62.22% of the whoremasters ever had non-marital sex partners, and of those who had sex with non-marital sex partners in the past year, 59.55% reported using condoms inconsistently. The total infection rate of HIV/syphilis/HSV-2 was 18.22% and the infection rates of HIV, syphilis and HSV-2 were 3.11%, 1.33% and 16.44%, respectively. The older whoremasters were more likely to have a higher HSV-2 infection rateAOR=1.044, 95%CI: 1.016-1.073, P=0.002], and those whoremasters not using a condom during the latest commercial sex were more likely to have a higher HSV-2 infection rateAOR=3.125, 95%CI: 1.229-7.945, P=0.017].  Conclusions  Though whoremasters in Kaiyuan City had a high awareness of AIDS related knowledge, they had high-risk behaviors and relatively high HIV and other STDs infection rates. Targeted interventions are needed to improve the risk awareness of STDs infection to promote consistent condom use in both commercial and non-marital sexual behaviors among whoremasters.
