Abstract

Lack of data regarding knowledge and intention to use pre-exposure prophylaxis (PrEP) among sex workers exists in Spain. We conducted a cross-sectional analysis based on data from SexCohort study, which included male (MSW) and trans women sex workers (TWSW), aged ≥18 and recruited in two community-based centres in Barcelona, Spain. Of 116 TWSW and 79 MSW, 49.1% and 58.2% had factual knowledge of PrEP, and 40.3% and 70.1% had the intention to use PrEP, respectively. In the multivariable analyses, we found that education and condomless anal sex with stable partners were associated with PrEP knowledge. Regarding intention to use PrEP, TWSW were less likely than MSW to report an intention to use it (aOR = 0.35, 95% CI: 0.16-0.74). Furthermore, intention to use PrEP was associated with being foreign-born, practicing chemsex, and visiting a medical service in the last 12 months. The results of this study inform future trans-specific guidance for PrEP to be effectively implemented in Spain.

摘要

西班牙缺乏关于性工作者对暴露前预防（PrEP）的知识和使用意愿的数据。我们基于 SexCohort 研究的数据进行了一项横断面分析，该研究纳入了年龄≥18 岁的巴塞罗那市两个社区中心招募的男性性工作者（MSW）和跨性别女性性工作者（TWSW）。在 116 名 TWSW 和 79 名 MSW 中，分别有 49.1%和 58.2%的人具有 PrEP 的事实知识，分别有 40.3%和 70.1%的人有使用 PrEP 的意愿。在多变量分析中，我们发现教育程度和与稳定伴侣进行无保护肛交与 PrEP 知识相关。关于使用 PrEP 的意愿，TWSW 报告使用意愿的可能性低于 MSW（调整后的 OR=0.35，95%CI：0.16-0.74）。此外，使用 PrEP 的意愿与出生在外国、进行化学性行为以及在过去 12 个月内到医疗服务机构就诊有关。本研究的结果为未来在西班牙有效实施针对跨性别者的 PrEP 提供了具体指导。
