IntroductionPrEP awareness in Latin America has been poorly characterized, with studies in Brazil, Mexico, and Peru highlighting low awareness. We assessed the association between higher risk of HIV infection, indicative of PrEP eligibility, and PrEP awareness among men who have sex with men (MSM) from these countries. MethodsMSM were recruited to complete an online survey via advertisements on Facebook, Grindr, and Hornet from March-June 2018. Eligible individuals were cisgender MSM, ≥18 years old, HIV negative or of unknown status, lived in these countries, and provided informed consent. Higher risk was defined using a CDC score indicating an increased risk of HIV infection and the suggested cutpoint of 10. We used Poisson regression models to calculate adjusted prevalence ratios (aPR) testing the association between higher risk and PrEP awareness; socio-demographics and other risk variables were considered potential confounders. Separate models were conducted for Brazil, Mexico, and Peru. ResultsAfter exclusion, 19,457 MSM were available for analysis. Overall PrEP awareness was 64.9%, with those from Brazil reporting highest awareness (68.8%), followed by Mexico (64.1%), and Peru (46.6%). In Brazil, 53.8% were classified as higher risk for HIV, 51.9% in Mexico, and 54.2% in Peru. Higher risk for HIV was associated with PrEP awareness among those in Brazil (aPR 1.04, 95% CI 1.01, 1.06), but no association was seen in Mexico or Peru. Additionally, having more than high school education, high income, daily use of gay social networking (GSN) applications, and substance use were associated with PrEP awareness in each country. ConclusionHigher risk of HIV infection was associated with increased PrEP awareness in Brazil. However, this association was weak indicating that MSM at higher risk, who would benefit from PrEP, are often not aware of this prevention strategy. In the remaining countries, there was no association between risk and awareness, highlighting a disconnect between need and knowledge. As PrEP is introduced, awareness should increase, as in Brazil where PrEP has been available longer. Interventions to increase PrEP awareness are paramount to increase PrEP uptake and prevent HIV infections. GSN applications and social media could play an important role to achieve this goal.

“…We have previously shown that PrEP awareness was 64.9% in 2018 among MSM from Brazil, Mexico and Peru, being higher in Brazil (68.8%), followed by Mexico (64.1%), and Peru (46.6%). Almost half of respondents were classified as higher risk for HIV and willingness to use PrEP was strongly associated with PrEP awareness in Brazil (aOR 1.66; 95% CI 1.52-1.81), Mexico (aOR 2.05; 95%CI 1.79-2.34) and Peru (aOR 1.84; 95%CI 1.51-2.26) [33]. Although Brazil has some data available [27][28][29][30], most of the countries in Latin America, including Mexico and Peru, have limited information about factors associated with PrEP awareness.…”

Introduction PrEP awareness in Latin America has been poorly characterized, with studies in Brazil, Mexico, and Peru highlighting awareness of 65% among gay, bisexual and other men who have sex with men (MSM). We assessed the association between higher risk of HIV infection, indicative of PrEP eligibility, and PrEP awareness among MSM from these countries. Methods This was a secondary analysis of a web-based survey advertised on social media platforms from March-June 2018 in Brazil, Mexico and Peru. Eligible individuals were cisgender MSM, ≥18 years old, HIV negative or of unknown status, who lived in these countries, and provided informed consent. Higher risk of HIV infection was defined as having 10 or more points in the HIV Risk Index for MSM (HIRI-MSM). We used multivariable Poisson regression models to calculate adjusted prevalence ratios (aPR) testing the association between higher risk for HIV and PrEP awareness. Results After exclusions, 19,457 MSM were included in this analysis. In Brazil, 53.8% were classified as higher risk for HIV, 51.9% in Mexico, and 54.2% in Peru. Higher risk for HIV was minimally associated with PrEP awareness among those in Brazil (aPR 1.04, 95% CI 1.01, 1.06), but no such association was observed in Mexico or Peru. Having more than a high school education, high income, daily use of geosocial networking (GSN) applications, and substance use were associated with PrEP awareness. Conclusion Higher risk of HIV infection was associated with increased PrEP awareness in Brazil. However, this association was weak indicating that PrEP awareness could be strengthened with further prevention efforts. In the remaining countries, results were non-conclusive between risk and awareness. Interventions to increase PrEP awareness are paramount to increase PrEP willingness and uptake and in turn prevent new HIV infections. Social media platforms could play an important role to achieve this goal.

Sex-on-premise venues, associated risk behaviors, and attitudes toward venue-based HIV testing among men who have sex with men in Lima, Perú

et al. 2020

Background: In Perú, HIV disproportionately affects men who have sex with men (MSM). Despite widespread access to treatment, the high rate of new HIV infections has remained unchanged over the last decade. Low knowledge of HIV status associated with late diagnosis is a key factor underlying the high HIV incidence observed in this setting, creating conditions for efficient onward transmission. Improving access to HIV testing and prevention services for those at highest risk is an important public health priority. Sex-on-premise venues (SOPVs)saunas, sex clubs, pornographic movie theaters, hourly hotels, and bars/discos with areas where sex is permittedmay be opportune sites for outreach; however, further research on SOPVs and the populations who frequent them is needed to inform such efforts. Methods: We conducted a cross-sectional online survey of adult MSM in Lima, Perú to evaluate patterns of SOPV attendance, associated sexual risk behaviors, and attitudes toward SOPV-based interventions. Participants were recruited through outreach to social media networks affiliated with local LGBTQ-aligned community groups. Our primary analytic objective was to estimate the association of HIV-related sexual risk behaviors and SOPV attendance. Additionally, we performed exploratory analyses to describe risk behavior stratified by SOPV category and to examine the relationship between SOPV attendance and the use of online platforms to meet sex partners. Results: Overall, 389 MSM completed the survey from November 2018 through May 2019, of whom 68% reported attending an SOPV in the last 3 months. SOPV attendance was associated with multiple sexual risk behaviors, including transactional sex, group sex, substance use around the time of sex, and higher number of partners. Over two thirds of SOPV attendees indicated they would accept HIV testing if offered at SOPVs.
