The aim of this study was to investigate the prevalence of human immunodeficiency virus (HIV) infection among transgender women and travestis and to analyze factors associated with HIV infection in Brazil.
TransOdara was a cross-sectional study on sexually transmitted infections among transgender women and travestis in five Brazilian cities between 2019 and 2021. Self-identified transgender women and travestis aged ≥18 years were recruited using respondent-driven sampling, completed an interviewer-led questionnaire, and provided samples to detect HIV. The outcome was the result of the rapid antigen testing for HIV. Adjusted prevalence ratios (aPR) and 95% confidence intervals (95% CI) were obtained using Poisson regression with robust variance.
Overall, this population was found to be especially vulnerable, with high levels of unstable housing and engagement in informal work. They usually resort to transactional sex as their main working activity. Half of them earned less than the Brazilian minimum wage, which characterizes a poor population living in dire conditions. The overall HIV prevalence was 34.40%. In the final model, the variables associated with the HIV prevalence were as follows: to be 31 years old or older, not studying at the moment they were interviewed, to be unemployed, and engaged in lifetime transactional sex.
We found disproportionately high HIV prevalence among transgender women and travestis, compared with a low prevalence among respective segments of Brazil's general population, which highlights the context of vulnerability in this population. The data point to the urgency for intensification and expansion of access to HIV prevention and strategies to stop discrimination in health care (among other services and contexts) and provide comprehensive services for this population.
本研究旨在调查巴西跨性别女性和跨性别男性中人类免疫缺陷病毒(HIV)感染的流行情况,并分析与 HIV 感染相关的因素。
TransOdara 是一项横断面研究,于 2019 年至 2021 年在巴西五个城市对跨性别女性和跨性别男性中的性传播感染进行研究。采用应答者驱动抽样法招募自我认同为跨性别女性和跨性别男性且年龄≥18 岁的参与者,完成由调查员主导的问卷调查,并提供样本以检测 HIV。结果是 HIV 快速抗原检测的结果。使用泊松回归和稳健方差获得调整后的患病率比(aPR)和 95%置信区间(95%CI)。
总体而言,该人群处于弱势地位,住房不稳定和从事非正规工作的比例较高。他们通常从事性交易作为主要工作活动。其中一半人的收入低于巴西最低工资,这表明他们是生活在困境中的贫困人群。总体 HIV 流行率为 34.40%。在最终模型中,与 HIV 流行率相关的变量如下:年龄在 31 岁或以上、访谈时未正在学习、失业和从事过终生性交易。
与巴西普通人群相应人群中的低流行率相比,我们发现跨性别女性和跨性别男性中 HIV 流行率不成比例地高,这突显了该人群处于弱势地位的情况。数据表明,迫切需要加强和扩大获得 HIV 预防的机会,并采取措施停止医疗保健(包括其他服务和环境)中的歧视,并为该人群提供全面的服务。
