HIV prevalence among transgender women is high worldwide. The objectives of the present study were to estimate the current prevalence of HIV and identify factors associated with high HIV burden among transgender women in Paraguay.
Transgender women aged ≥15 years in four regions of Paraguay were recruited by Starfish sampling between February and March 2021.
In total, 322 transgender women were included. Mean age was 31 years (range 15-67), and 102 had positive HIV test results (31.7%, 95% confidence interval [CI] 26.6-37.1). In multivariable analysis, factors associated with HIV infection were age at first intercourse ≤17 years (adjusted odds ratio [aOR] 5.47; 95% CI 1.05-28.42), >10 years difference in age with the last sexual partner (aOR 1.60; 95% CI 1.04-2.46), substance use (mostly cocaine) (aOR 3.00; 95% CI 1.47-6.12), higher risk perception (aOR 3.08; 95% CI 1.53-6.17), not testing for HIV (aOR 1.23; 95% CI 1.09-1.39), and accessed by a peer educator (aOR 3.86; 95% CI 1.77-8.38).
Sexual debut as a minor and a large age difference with sexual partners are associated with high burden of HIV among transgender women in Paraguay. Our study corroborates the finding of cocaine use during sex as a risk factor for HIV. Prevention programmes must address structural and social vulnerabilities to stem the tragically high burden of HIV among transgender women.
全世界范围内,跨性别女性的 HIV 感染率很高。本研究的目的是估计目前巴拉圭跨性别女性中的 HIV 流行率,并确定与 HIV 高负担相关的因素。
2021 年 2 月至 3 月期间,通过海星抽样方法招募了巴拉圭四个地区年龄≥15 岁的跨性别女性。
共纳入 322 名跨性别女性。平均年龄为 31 岁(范围 15-67 岁),102 人 HIV 检测结果呈阳性(31.7%,95%置信区间 [CI] 26.6-37.1)。多变量分析显示,与 HIV 感染相关的因素包括初次性行为年龄≤17 岁(调整后的优势比 [aOR] 5.47;95% CI 1.05-28.42)、与最近一次性伴侣的年龄差异>10 岁(aOR 1.60;95% CI 1.04-2.46)、物质使用(主要是可卡因)(aOR 3.00;95% CI 1.47-6.12)、较高的风险感知(aOR 3.08;95% CI 1.53-6.17)、未接受 HIV 检测(aOR 1.23;95% CI 1.09-1.39)和通过同伴教育者获得(aOR 3.86;95% CI 1.77-8.38)。
未成年开始性行为和与性伴侣的年龄差异较大与巴拉圭跨性别女性的 HIV 负担沉重有关。我们的研究证实了在性行为中使用可卡因是 HIV 感染的一个风险因素。预防计划必须解决结构性和社会脆弱性问题,以遏制跨性别女性中 HIV 感染率的悲剧性增加。
