Sexual exposure to HIV in Angolan men who have sex with men immigrants: A cross-sectional study in Portugal and Brazil

Abstract

Background In different contexts, international migrants are vulnerable to health disparities that increase the risk of HIV/AIDS exposure and continue to bear a significant burden of new virus infections in developed and developing countries. In this study, we sought to examine sexual practices and factors linked to HIV exposure among a sample of Angolan men who have sex with men (MSM) immigrants. Methods The study was conducted in two Portuguese-speaking countries, Brazil and Portugal, and involved 250 Angolan MSM immigrants between September 2020 and February 2021, using sampling methods to constitute the sample and the HIV Incidence Risk Index (HIRI) to define virus exposure risk. Odds ratio (OR) and adjusted odds ratio (aOR) were used to calculate the chances of higher HIRI index in the sample. Results Our results showed that 76.8% of participants presented a high HIRI index, influenced by the practice of chemsex (aOR: 4.26), having a known/repeated partner (aOR: 4.59), and engaging in passive sex without a condom in the last 30 days (aOR: 1.29) or 6 months (aOR: 1.98). Conclusions It is crucial to focus on this vulnerable population and implement sexual health policies that integrate combined HIV prevention measures aimed at immigrant MSM.
