Abstract

Background: Our study aimed to measure HIV prevalence and associated risk factors among men who have sex with men (MSM) in three regions of Paraguay in 2020. Methods: MSM were recruited for cross-sectional surveys in three regions of Paraguay using respondent-driven sampling. Interview were conducted face-to-face to collect demographic characteristics and risk and preventive behaviors. The analysis assessed HIV prevalence and associated risk factors in the three samples of MSM within each region. Results: A total of 1,207 MSM were recruited, including 559 in Asunción-Central, 245 in Alto Paraná, and 403 in Caaguazú. HIV prevalence was 24.2% (95% CI 20.6–27.9) in Asunción-Central, 10.2% (95% CI 6.7–14.6) in Alto Paraná, and 3.2% (95% CI 1.7–5.4) in Caaguazú. In Asunción-Central, associations with HIV were age ≥25 years (1.86, 95% CI 1.15–3.00), being employed (1.82, 95% CI 1.07–3.11), self-reporting as homosexual (1.90, 95% CI 1.06–3.43), having sex with a known HIV-positive partner acquisition (4.19, 95% CI 2.37–7.43), self-perceived as being at higher risk for HIV acquisition (4.15, 95% CI 2.54–6.77), and able to access condoms and lubricants (1.82, 95% CI 1.08–3.05). In Alto Paraná, associations with HIV were self-reporting as homosexual (4.33, 95% CI 1.19–15.65) and having higher HIV knowledge (2.53, 95% CI 0.97–6.61). In Caaguazú, associations with HIV were self-reporting as homosexual (7.06, 95% CI 1.53–32.46) and being diagnosed with depression (4.68, 95% CI 0.89–24.43). Conclusions: HIV prevalence among MSM in Paraguay varied by region, being highest in the capital and major metropolitan area of Asunción-Central, followed by the border area of Alto Paraná. While being self-identified as homosexual was associated with HIV in all three regions, other associations differed, indicating prevention programs need to be tailored to the locale.
