Globally, transgender women sex workers have a high prevalence of HIV and condomless receptive anal intercourse with male clients (CRAIMC). We investigated the prevalence of CRAIMC and factors associated with CRAIMC among transgender women sex workers in China.
In 2014, we anonymously interviewed 220 transgender women sex workers face to face in Shenyang, China. Those who self-reported as HIV negative or as having unknown HIV serostatus were invited to take up free, anonymous HIV rapid testing (n=183); 90 did so. Using CRAIMC in the last month as the dependent variable, three types of associated factors were investigated, in addition to background factors: feminizing medical interventions, sex work and perceptions related to condom use. Univariate and multiple logistic regression models were fitted.
Of the participants, 16.8% self-reported as HIV positive and 9.1% were detected to be HIV positive through free HIV testing; 26.8% had had CRAIMC in the last month, 45.5% had performed sex work in other Chinese cities (last year), and 23.2% had had condomless anal intercourse with men who were non-clients. In the adjusted analysis, significant factors associated with CRAIMC (last month) included the following: 1) any feminizing medical intervention performed (adjusted odds ratio, AOR: 2.22); 2) sex-work-related factors, including recruitment of male clients most often at hotels (AOR: 5.02) and charge per episode of transactional sex (201 to 400 RMB, AOR: 0.27; reference group: ≤100 RMB); and 3) perceptions related to condom use, including perceived transgender identity's impact on condomless sex such as wearing feminine attire, concern about exposing their status as a transgender woman to male clients (AOR: 1.20) and perceived self-efficacy of consistent condom use with male clients (AOR: 0.56). Perceived self-efficacy of consistent condom use with male clients fully mediated the association between perceived transgender identity's impact on condomless sex and CRAIMC.
HIV prevalence among transgender women sex workers was high but probably underestimated. The high prevalence of condomless anal intercourse with male non-clients and high mobility in sex work among this population in China are causes for concern. Risk factors for CRAIMC were multidimensional and should be considered when designing interventions targeting transgender women sex workers. Such interventions are urgently needed.
在全球范围内,跨性别女性性工作者感染艾滋病毒的比例很高,并且与男性客户存在无保护的接受性肛交行为(CRAIMC)。我们调查了中国跨性别女性性工作者中CRAIMC的流行情况以及与CRAIMC相关的因素。
2014年,我们在中国沈阳对220名跨性别女性性工作者进行了面对面的匿名访谈。那些自我报告为艾滋病毒阴性或艾滋病毒血清学状态未知的人被邀请接受免费的匿名艾滋病毒快速检测(n = 183);90人接受了检测。以上个月的CRAIMC作为因变量,除背景因素外,还调查了三种相关因素:女性化医疗干预、性工作以及与使用避孕套相关的观念。拟合了单变量和多变量逻辑回归模型。
参与者中,16.8%自我报告为艾滋病毒阳性,通过免费艾滋病毒检测发现9.1%为艾滋病毒阳性;26.8%在上个月有过CRAIMC行为,45.5%(去年)在其他中国城市从事过性工作,23.2%与非客户男性有无保护的肛交行为。在调整分析中,与上个月CRAIMC相关的显著因素包括:1)进行过任何女性化医疗干预(调整后的优势比,AOR:2.22);2)与性工作相关的因素,包括最常在酒店招揽男性客户(AOR:5.02)以及每次性交易收费(201至400元人民币,AOR:0.27;参照组:≤100元人民币);3)与使用避孕套相关的观念,包括认为跨性别身份对无保护性行为的影响,如穿着女性服装、担心向男性客户暴露自己作为跨性别女性的身份(AOR:1.20)以及认为与男性客户始终使用避孕套的自我效能感(AOR:0.56)。认为与男性客户始终使用避孕套的自我效能感完全介导了跨性别身份对无保护性行为的影响与CRAIMC之间的关联。
跨性别女性性工作者中的艾滋病毒感染率很高,但可能被低估了。该人群中与非客户男性的无保护肛交行为高发以及性工作中的高流动性令人担忧。CRAIMC的风险因素是多维度的,在设计针对跨性别女性性工作者的干预措施时应予以考虑。此类干预措施亟待实施。
