HIV self-testing has been available in Spain since 2017 as a diagnostic tool to promote earlier diagnosis. We aimed to assess awareness and previous use of HIV self-testing in a sample of men who have sex with men (MSM) recruited online more than 2 years after its legal authorization in Spain.
We analyzed 5,492 MSM recruited between May and July 2020 in gay dating apps/websites and other social networks. We estimated the proportion of participants who were aware of the existence of HIV self-testing and the proportion who reported previous use. To identify factors associated with both outcomes we built two Poisson regression models. Among those who reported previous use we described several aspects related to their last self-test.
Awareness of HIV self-test was reported by 29.7% and its previous use by 5% of participants. Awareness was independently associated with recruitment in gay dating apps/websites, being ≥40 years old, born in Spain-other European countries, having higher educational level, living in medium-small municipalities and living sex life openly. Independent associations were also found with having received a sexually transmitted infection diagnosis (STI) or an HIV negative test in the last 12 months, and being HIV positive. Use was significantly higher among participants who were paid for sex or diagnosed with an STI in the last 12 months and who received their last HIV test in the preceding year. Self-testing occurred recently, with kits acquired at pharmacies and carried out alone.
Awareness and use probably have not increased sufficiently in order to make a relevant impact to the promotion of early HIV diagnosis. Additional efforts, mainly focused on less favored MSM, should be made to take better advantage of the possibilities offered by this testing option.
自 2017 年以来,西班牙已经将 HIV 自我检测作为一种诊断工具,以促进更早的诊断。我们旨在评估在西班牙法律授权两年多后,通过在线招募的男男性行为者(MSM)样本中,对 HIV 自我检测的知晓率和以往使用情况。
我们分析了 2020 年 5 月至 7 月间在同性恋约会应用程序/网站和其他社交网络中招募的 5492 名 MSM。我们估计了知晓 HIV 自我检测存在的参与者比例,以及报告以往使用情况的参与者比例。为了确定与这两个结果相关的因素,我们建立了两个泊松回归模型。在报告有过以往使用的参与者中,我们描述了与他们最后一次自我检测相关的几个方面。
29.7%的参与者知晓 HIV 自我检测,5%的参与者报告曾使用过。知晓情况与在同性恋约会应用程序/网站中招募、年龄≥40 岁、出生于西班牙-其他欧洲国家、受教育程度较高、居住在中小城市以及公开性生活有关。在过去 12 个月中接受过性传播感染(STI)诊断或 HIV 阴性检测,以及 HIV 阳性的参与者,也与知晓情况存在独立关联。在过去 12 个月中从事过性交易或被诊断出患有 STI 的参与者,以及在过去一年中接受过最后一次 HIV 检测的参与者,自我检测的使用率显著更高。自我检测发生在最近,试剂盒是在药店购买的,且是独自进行的。
为了对促进早期 HIV 诊断产生重大影响,知晓率和使用率可能还没有显著提高。应该做出更多的努力,主要针对处于不利地位的 MSM,以更好地利用这种检测选择所提供的可能性。
