BACKGROUND: Despite efforts to stop HIV epidemic in Latin America, new HIV cases continue to increase in the region especially among young MSM (YMSM). This study aims to assess if sociodemographic characteristics are associated with self-reported HIV positive status among YMSM from three Latin American countries. METHODS: Cross-sectional web-based survey advertised on dating apps (Grindr and Hornet) and Facebook in Brazil, Mexico and Peru. For this analysis, we included YMSM aged 18-24 years who self-reported their HIV status. We used multivariable logistic regression models for each country separately to verify if sociodemographic characteristics (race, education and income) were associated with HIV self-reported status after adjusting for behavior characteristics (sexual attraction and steady partner). RESULTS: Among 43,687 MSM who initiated the questionnaire, 27,318 (62.5%) reported their HIV status; 7001 (25.6%) of whom were YMSM. Most YMSM (83.4%) reported an HIV test in the past year, and 15.7% reported an HIV positive status in Peru, 8.4% in Mexico and 7.7% in Brazil. In adjusted models, low-income was associated with higher odds of self-reported HIV positive status in Brazil (aOR = 1.33, 95%CI: 1.01-1.75) and Peru (aOR = 1.56, 95%CI: 1.02-2.40), but not in Mexico. Lower education was associated with higher odds of self-reported HIV positive status only in Brazil (aOR = 1.35, 95%CI: 1.05-1.75). CONCLUSIONS: In this large, cross-country study, self-reported HIV positive status among YMSM was high. Lower socioeconomic status was associated with higher odds of self-reported HIV positive status in Brazil and Peru. There is an urgent need for HIV prevention interventions targeting YMSM, and efforts to address low-income YMSM are especially needed in Peru and Brazil.
背景:尽管拉丁美洲在努力遏制艾滋病毒的流行,但该地区的新艾滋病毒感染病例仍在持续增加,尤其是年轻男男性行为者(YMSM)。本研究旨在评估社会人口统计学特征是否与来自拉丁美洲三个国家的 YMSM 自我报告的艾滋病毒阳性状况相关。
方法:在巴西、墨西哥和秘鲁,通过约会应用程序(Grindr 和 Hornet)和 Facebook 进行基于网络的横断面调查。在这项分析中,我们纳入了年龄在 18-24 岁之间、自我报告艾滋病毒状况的 YMSM。我们使用多变量逻辑回归模型分别对每个国家进行分析,以验证社会人口统计学特征(种族、教育和收入)在调整行为特征(性吸引和稳定伴侣)后是否与自我报告的 HIV 状况相关。
结果:在开始问卷的 43687 名男男性行为者中,有 27318 名(62.5%)报告了他们的 HIV 状况;其中 7001 名(25.6%)为 YMSM。大多数 YMSM(83.4%)报告在过去一年中进行了 HIV 检测,15.7%报告在秘鲁、8.4%在墨西哥和 7.7%在巴西 HIV 阳性。在调整后的模型中,在巴西(调整后的比值比 [aOR] = 1.33,95%置信区间 [CI]:1.01-1.75)和秘鲁(aOR = 1.56,95%CI:1.02-2.40),低收入与自我报告的 HIV 阳性状态的可能性更高相关,但在墨西哥则不然。较低的教育程度仅与巴西自我报告的 HIV 阳性状态的可能性更高相关(aOR = 1.35,95%CI:1.05-1.75)。
结论:在这项大型跨国研究中,YMSM 自我报告的 HIV 阳性率很高。较低的社会经济地位与巴西和秘鲁自我报告的 HIV 阳性状态的可能性更高相关。迫切需要针对 YMSM 的艾滋病毒预防干预措施,特别是在秘鲁和巴西,需要针对低收入 YMSM 采取措施。
