RESUMO
BACKGROUND: Gay, bisexual, and other men who have sex with men (MSM) with a higher perceived risk of HIV are more aware of and willing to use pre-exposure prophylaxis (PrEP). PrEP is an effective HIV prevention strategy, but there is a lack of data on how PrEP use might moderate the relationship between sexual risk behavior and perceived risk of HIV. Moreover, most studies measure perceived risk of HIV via a single question. OBJECTIVE: We estimated the moderating effect of PrEP use on the association between sexual risk behavior and perceived risk of HIV, measured with the 8-item Perceived Risk of HIV Scale (PRHS), among Brazilian MSM. METHODS: A cross-sectional, web-based survey was completed by Brazilian Hornet app users aged ≥18 years between February and March 2020. We included data from cisgender men who reported sex with men in the previous 6 months. We evaluated the moderating effect of current PrEP use on the association between sexual risk behavior, measured via the HIV Incidence Risk Index for MSM (HIRI-MSM), and perceived risk of HIV, measured by the PRHS. Higher HIRI-MSM (range 0-45) and PRHS (range 10-40) scores indicate greater sexual behavioral risk and perceived risk of HIV, respectively. Both were standardized to z scores for use in multivariable linear regression models. RESULTS: Among 4344 cisgender MSM, 448 (10.3%) were currently taking PrEP. Current PrEP users had a higher mean HIRI-MSM score (mean 21.0, SD 9.4 vs mean 13.2, SD 8.1; P<.001) and a lower mean PRHS score (mean 24.6, SD 5.1 vs mean 25.9, SD 4.9; P<.001) compared to those not currently taking PrEP. In the multivariable model, greater HIRI-MSM scores significantly predicted increased PRHS scores (ß=.26, 95% CI 0.22-0.29; P<.001). PrEP use moderated the association between HIRI-MSM and PRHS score (interaction term ß=-.30, 95% CI -0.39 to -0.21; P<.001), such that higher HIRI-MSM score did not predict higher PRHS score among current PrEP users. CONCLUSIONS: Our results suggest current PrEP users have confidence in PrEP's effectiveness as an HIV prevention strategy. PrEP's effectiveness, positive psychological impact, and the frequent HIV testing and interaction with health services required of PrEP users may jointly influence the relationship between sexual risk behavior and perceived risk of HIV among PrEP users.

Knowledge about HIV transmission and prevention is a necessary step for adopting preventive behaviors. We assessed HIV knowledge and its correlation with the perceived accuracy of the "Undetectable = Untransmittable" (U=U) slogan in an online sample with 401 adult Brazilians. Overall, 28% of participants showed high HIV knowledge level. The perceived accuracy of the U=U slogan significantly correlated with HIV knowledge. Younger participants, those reporting lower income or lower education, or who had never tested for HIV showed poorer HIV knowledge. Filling gaps of knowledge among specific populations is urgent in order to increase preventive behaviors and decrease HIV stigma.

BACKGROUND: In order to end the HIV epidemic by 2030, combination HIV prevention including pre-exposure prophylaxis (PrEP) should be widely available, especially for the most vulnerable populations. In Latin America and the Caribbean (LAC), only 14 out of 46 countries have access to PrEP. In Brazil and Mexico, PrEP has been provided at no cost through the Public Health System since 2017 and 2021, respectively. Thus, HIV physicians' perspectives about PrEP and other prevention strategies may differ. This study aimed to compare awareness, knowledge, and attitudes related to PrEP and other prevention strategies among HIV physicians from Brazil and Mexico. METHODS: Cross-sectional, web-based survey targeting physicians who prescribe antiretrovirals from both countries. Participants answered questions on socio-demographic, medical experience, awareness, knowledge, and attitudes towards PrEP and other HIV prevention strategies. We stratified all variables per country and compared frequencies using Chi-square, Fisher exact, and Wilcoxon-Mann-Whitney tests, as appropriate. RESULTS: From January-October 2020, 481 HIV physicians were included: 339(70.5%) from Brazil, 276(57.4%) male, and median age was 43 years (IQR = 36-53). Awareness of PrEP did not differ between Brazil and Mexico (84.6%), while awareness of other prevention strategies, including post-exposure prophylaxis and new PrEP technologies, was higher in Brazil. More Brazilians perceived U=U as completely accurate compared to Mexicans (74.0% vs. 62.0%, P < .001). Willingness to prescribe PrEP was 74.2%, higher among Brazilians (78.2%, P = .01). Overall, participants had concerns about consistent access to PrEP medication and the risk of antiretroviral resistance in case of acute HIV infection or seroconversion. The main barriers reported were assumptions that users could have low PrEP knowledge (62.0%) or limited capacity for adherence (59.0%). Compared to Brazilians, Mexicans reported more concerns and barriers to PrEP prescription (all; P ≤ .05), except for consistent access to PrEP medication and the lack of professionals to prescribe PrEP (both; P ≤ .01). CONCLUSIONS: Although awareness of PrEP was similar in Brazil and Mexico, differences in knowledge and attitudes may reflect the availability and stage of PrEP implementation in these countries. Strengthening and increasing information on PrEP technologies and other HIV prevention strategies among HIV physicians could improve their comfort to prescribe these strategies and facilitate their scale-up in LAC.

Background: Pre-exposure prophylaxis (PrEP) use in Brazil remains low despite free national access. We explored associations of HIV knowledge and internalized homonegativity with PrEP use among PrEP-eligible men who have sex with men (MSM). Methods: Brazilian Hornet users completed an online, cross-sectional survey in February-March 2020. We included cis-men ≥18 years old who reported recent sex with men and were PrEP-eligible per the following: condomless anal intercourse, partner(s) living with HIV, transactional sex, and/or sexually transmitted infection. Our outcome was current PrEP use, defined by the response, "I am currently taking PrEP." Key predictors included the HIV/AIDS Knowledge Assessment (HIV-KA) and Reactions to Homosexuality Scale (RHS); higher scores indicate greater knowledge and greater internalized homonegativity, respectively. Scales were standardized for analysis. Associations with current PrEP use were estimated using adjusted odds ratios (aOR) with 95% confidence intervals (95%CI). Findings: Among 2398 PrEP-eligible MSM, n = 370 (15·4%) reported current PrEP use. Increasing HIV-KA scores were associated with greater odds of PrEP use (aOR 1·70 [95%CI 1·41-2·04], p < 0·001), and increasing RHS scores with lower odds of PrEP use (aOR 0·83 [95%CI 0·73-0·96], p = 0·010). PrEP use was lower among 18-24 versus 40+-years-old MSM (aOR 0·43 [95%CI 0·27-0·69], p = 0·005), and in Black versus White/Asian respondents (aOR 0·51 [95%CI 0·31-0·85], p = 0·040). Interpretation: Among PrEP-eligible Brazilian MSM, HIV knowledge was associated with increased PrEP use and internalized homonegativity with decreased use. Wider dissemination of HIV prevention knowledge and addressing stigma experienced by MSM could promote increased PrEP use.

Exploramos as associações entre conhecimento sobre HIV e homonegatividade internalizada com o uso de PrEP entre homens que fazem sexo com homens (HSH) elegíveis para PrEP. Métodos: Brasileiros usuários do Hornet completaram uma pesquisa seccional online em fevereiro-março de 2020. Foram incluídos homens cis ≥18 anos, que reportaram sexo recente com homens e elegíveis para PrEP. O desfecho principal foi uso de PrEP, definido por: "Estou atualmente tomando PrEP." Os principais preditores incluíram escalas de Conhecimento em HIV/aids (HIV-KA) e de Reações à Homossexualidade (RHS); escores mais altos indicam maior conhecimento e maior homonegatividade internalizada, respectivamente. As escalas foram padronizadas para análise. Associações com uso da PrEP foram estimadas usando razões de chances ajustadas (aOR) com intervalos de confiança de 95% (IC95%). Resultados: Entre 2.398 HSH elegíveis para PrEP, 370 (15,4%) relataram o uso atual de PrEP. Maior conhecimento em HIV/AIDS foi associado a maior chance de uso de PrEP (aOR 1·70 [IC 95% 1·412·04], p < 0·001), e maior homonegatividade internalizada com menor chance de uso de PrEP (aOR 0·83 [95% IC 0·730·96], p = 0·010). Uso de PrEP foi menor entre HSH de 1824 vs. 40+ anos (aOR 0·43 [IC95%:0·270·69], p = 0·005), e entre pretos versus brancos/asiáticos (aOR 0·51 [IC95% 0·310·85], p = 0·040). Interpretação: Entre brasileiros HSH elegíveis para a PrEP, o conhecimento do HIV foi associado ao aumento do uso da PrEP e homonegatividade internalizada com a diminuição do uso.

RESUMO
Different strategies have been used to reach men who have sex with men (MSM) and transgender women (TGW) for HIV prevention services. We described the characteristics of MSM and TGW attending a large HIV prevention service in Brazil according to different recruitment strategies or referrals. A total of 2713 individuals (2246[82.8%] MSM and 467[17.2%] TGW) attended the service. Among HIV-negative MSM and TGW, 74.6% and 82.8% were eligible for pre-exposure prophylaxis (PrEP), respectively. PrEP uptake among MSM and TGW was 56.4% and 39.1%, respectively. Participants were mostly referred by peers (43.6%), followed by web-based (24.1%) and venue-based recruitment (16.2%). More young and Black MSM were referred from venue-based recruitment, and web-based strategies more frequently referred MSM with higher education. TGW who were younger and had higher education were more frequently referred from venue-based recruitment. Web-based recruitment failed to reach TGW. Multiple strategies were complementary to reach diverse MSM and TGW populations.
RESUMEN: Diferentes estrategias se han usado para alcanzar hombres que tienen sexo con hombres (HSH) y mujeres trans (MT) en los servicios preventivos del VIH. Describimos las características de HSH y MT que acudieron a un servicio de prevención del VIH en Brasil, de acuerdo con diferentes estrategias de reclutamiento. Un total de 2713 personas (2246[82.8%] HSH y 467[17.2%] MT) asistieron al servicio y aquellos con resultado negativo al VIH (74.6% de HSH y 82.8% de MT) fueron candidatos a la profilaxis preexposición, siendo iniciada por 56.4% y 39.1%, respectivamente. Las referencias al servicio vinieron de pares (43.6%), en línea (24.1%) o por algún sitio (16.2%). Mayoritariamente los HSH jóvenes y negros, y las MT jóvenes con educación superior fueron referidos de algún sitio; mientras que los HSH con educación superior fueron en línea. Este último reclutamiento no sirvió para las MT. Múltiples estrategias fueron complementarias para alcanzar HSH y MT.

After more than a year since the novel coronavirus (SARS-CoV-2) disease 2019 or COVID-19 has reached the status of a global pandemic, the number of COVID-19 cases continues to rise in Brazil. As no effective treatment been approved yet, only mass vaccination can stop the spread of SARS-CoV-2 and end the COVID-19 pandemic. Multiple COVID-19 vaccine candidates are under development and some are currently in use. This study aims to describe the characteristics of individuals who have registered in an online platform to participate in clinical trials for COVID-19 vaccines. Additionally, participants' characteristics according to age and presence of comorbidities associated with severe COVID-19 and differences of SARS-CoV-2 testing across different geographical areas/neighborhoods are provided. This was a cross-sectional web-based study conducted between September and December/2020, aiming to reach individuals aged ≥18 years who live in Rio de Janeiro metropolitan area, Brazil. Among 21,210 individuals who completed the survey, 20,587 (97.1%) were willing to participate in clinical trials for COVID-19 vaccines. Among those willing to participate, 57.8% individuals were aged 18-59 years and had no comorbidity, 33.7% were aged 18-59 years and had at least one comorbidity, and 8.6% were aged ≥ 60 years regardless the presence of any comorbidity. Almost half (42.6%) reported ever testing for COVID-19, and this proportion was lower among those aged ≥ 60 years (p < 0.001). Prevalence of positive PCR results was 16.0%, higher among those aged 18-59 years (p < 0.009). Prevalence of positive antibody result was 10.0%, with no difference across age and comorbidity groups. Participants from areas/neighborhoods with higher Human Development Index (HDI) reported ever testing for SARS-CoV-2 more frequently than those from lower HDI areas. Interest to participate in clinical trials for COVID-19 vaccines candidates in Rio de Janeiro was significantly high. The online registry successfully reached out a large number of individuals with diverse sociodemographic, economic and clinical backgrounds.

Internalized homonegativity results from the acceptance of negative attitudes about one's same-sex orientation, which has negative consequences for the health of gay, bisexual and other men who have sex with men (GBM). We translated the 7-item Reactions to Homosexuality Scale (RHS) to Brazilian Portuguese and assessed its factor structure, validity and reliability. The first step included the translation, back-translation, evaluation, peer review, and pre-testing of the scale. Then, we piloted the scale in two convenience samples of adult Brazilians recruited online during October 2019 and February to March 2020 through advertisements on Grindr and Hornet, respectively. The largest sample was randomly split into two groups for exploratory factor analysis (EFA) then confirmatory factor analysis (CFA). Criterion and construct validity were assessed via correlations between scale scores and study variables. A total of 5573 GBM (sample 1: 218; sample 2: 5355) completed the RHS. EFA (N = 2652) yielded two eigenvalues greater than one (Factor 1: 3.5 and Factor 2: 1.1). A one-factor solution provided the most interpretable model based on examination of scree plot and item factor loadings (χ2(14) = 1373.1, p < 0.001; CFI = 0.89; TLI = 0.84; RMSEA = 0.19; SRMS = 0.09). Though one-factor CFA showed moderate fit, freeing errors terms to covary, based on item content and interpretation, significantly improved model fit (χ2(12) = 309.1, p < .001; CFI = 0.97; TLI = 0.96; RMSEA = 0.09; SRMR = 0.02). As hypothesized, men who did not self-identify as gay (mean score 17.9 compared to those self-identifying as gay: 11.8) and men who reported no sex with men in the past 6 months (mean score 12.6 compared to those who reported sex with men: 10.6) scored higher reflecting higher internalized homonegativity. The RHS was effectively translated and validated in Brazilian Portuguese and can be used to evaluate the role of internalized homonegativity on GBM's health, as well as its impact on the uptake of HIV prevention technologies.

BACKGROUND: Valid and reliable instruments are needed to measure the multiple dimensions of perceived risk. The Perceived Risk of HIV Scale is an 8-item measure that assesses how people think and feel about their risk of infection. We set out to perform a cross-cultural adaptation of the scale to Brazilian Portuguese among key populations (gay, bisexual and other men who have sex with men and transgender/non-binary) and other populations (cisgender heterosexual men and cisgender women). METHODS: Methodological study with cross-sectional design conducted online during October/2019 (key populations [sample 1] and other populations) and February-March/2020 (key populations not on pre-exposure prophylaxis [sample 2]). Cross-cultural adaptation of the Perceived Risk of HIV Scale followed Beaton et al. 2000 guidelines and included confirmatory factor analysis, differential item functioning (DIF) using the Multiple-Indicator Multiple-Cause model, and concurrent validity to verify if younger individuals, those ever testing for HIV, and engaging in high-risk behaviors had higher scores on the scale. RESULTS: 4342 participants from key populations (sample 1 = 235; sample 2 = 4107) and 155 participants from other populations completed the measure. We confirmed the single-factor structure of the original measure (fit indices for sample 1 plus other populations: CFI = 0.98, TLI = 0.98, RMSEA = 0.07; sample 2 plus other populations: CFI = 0.97, TLI = 0.95, RMSEA = 0.09). For the comparisons between key populations and other populations, three items (item 2: "I worry about getting infected with HIV", item 4: "I am sure I will not get infected with HIV", and item 8: "Getting HIV is something I have") exhibited statistically significant DIF. Items 2 and 8 were endorsed at higher levels by key populations and item 4 by other populations. However, the effect of DIF on overall scores was negligible (0.10 and 0.02 standard deviations for the models with other populations plus sample 1 and 2, respectively). Those ever testing for HIV scored higher than those who never tested (p < .001); among key populations, those engaging in high-risk behaviors scored higher than those reporting low-risk. CONCLUSION: The Perceived Risk of HIV Scale can be used among key populations and other populations from Brazil.

ABSTRACT In March 2020, telemedicine and HIV self-testing were adopted by Brazilian Public Health services to minimize disruptions in pre-exposure prophylaxis (PrEP) access and delivery during the COVID-19 pandemic. To understand the acceptability of PrEP teleconsultation and HIV self-testing, we conducted a web-based study during social distancing period (April-May, 2020) among men who have sex with men and transgender/non-binary individuals using social media. Out of the 2375 HIV negative respondents, 680 reported PrEP use and were included in this analysis. Median age was 33 years (IQR: 28-40), 98% cisgender men, 56% white, 74% high education, and 68% middle/high income. Willingness to use HIVST was 79% and 32% received an HIV self-testing during social distancing period. The majority reported preference for PrEP/HIV self-testing home delivery instead of collecting at the service. PrEP teleconsultation was experienced by 21% and most reported feeling satisfied with the procedures. High acceptability of PrEP teleconsultation was reported by 70%. In ordinal logistic model, having higher education was associated with high aceptability of PrEP teleconsultation (aOR:1.62; 95%CI: 1.07-2.45). Our results point out that PrEP teleconsultation and PrEP/HIV self-testing home delivery could be implemented by PrEP services in Brazil to avoid PrEP shortage during the COVID-19 pandemic and thereafter as an option to increase retention and adherence.

We conducted a web-based survey to understand the impact of social distancing measures on Brazilian MSM and transgender/non-binary lives. A total of 3486 respondents were included in this analysis and the great majority were cismen (98%). The median age was 32 years (IQR: 27-40), 44% non-white, 36% low schooling and 38% low income. Most of participants reported HIV negative/unknown status (77%). Participants on-PrEP reported more condomless anal sex than those off-PrEP. Conversely, 24% off-PrEP were at substantial HIV-risk. PrEP/ART continuation were reported by the majority, despite reports of impediments to medication refill. Transgender/non-binary reported more mental health problems and challenges to access health care. Social and racial disparities were associated with unattainability of maintaining social distancing. Tailored social and economic support policies during COVID-19 pandemic should be made available to these populations. Challenges for PrEP/ART access will demand the implementation of innovative solutions to avoid the expansion of the HIV epidemic.

BACKGROUND: HIV-related stigma, or the degree to which people living with HIV endorse negative stereotypes associated with HIV, is associated with poor continuum of care outcomes. We translated the 12-item Short HIV Stigma scale and evaluated its psychometric properties in a Brazilian context with regard to construct validity and reliability. METHODS: The first step included translation, back-translation, evaluation, peer review, and pre-testing of the Short HIV Sigma scale developed by Reinius et al. (Health Qual Life Outcomes 15(1):115, 2017). The second step involved piloting the scale in three convenience samples of adults recruited online through advertisements on different platforms: Grindr (October/2019) and Hornet (February-March/2020), geospatial network apps for sexual encounters for gay, bisexuals and other men who have sex with men, and social media apps (Facebook and WhatsApp, October/2019). The psychometric evaluation included confirmatory factor analysis, differential item functioning using the Multiple-Indicator Multiple-Cause model, and correlations between subscale scores and antiretroviral treatment use and adherence. Reliability was assessed using Cronbach's alpha, and ordinal alpha and omega from the polychoric correlation matrix. RESULTS: In total, 114, 164, and 1824 participants completed the measure items through Grindr, social media, and Hornet, respectively. We confirmed a 4-factor structure with factors for personalized stigma (3 items), disclosure concerns (3 items), concerns with public attitudes (3 items), and negative self-image (3 items). Small differential item functioning with respect to sample was found for one item ("I feel guilty because I have HIV"), which did not substantively influence estimates of latent factor scores. Grindr and Hornet's participants scored significantly higher than social media participants on all factors except personalized stigma. Higher subscale scores correlated with antiretroviral treatment use among participants from Hornet and with lower treatment adherence in participants from Grindr and Hornet. Reliability as measured by Cronbach's alpha, ordinal alpha and omega were 0.83, 0.88 and 0.93 for the entire scale. DISCUSSION: The Brazilian Portuguese version of the Short HIV Stigma scale had satisfactory psychometric properties with present results suggesting that scores from different samples may be compared without concern that measurement differences substantively influence results though further studies with greater representation of women and heterosexual men are warranted.

Abstract COVID-19 public health responses such as social distancing and community containment measures protocols are critical to preventing and containing the spread of coronavirus. Brazil accounts for almost half of Latin American HIV cases and Rio de Janeiro is the city with the second largest number of AIDS. Clinical appointments and pharmacy antiretroviral refills may be impaired due to restricted traffic and possible lockdowns, preventing people living with HIV and those using PrEP from accessing needed antiretrovirals. We hereby describe the telemedicine procedures implemented in a large PrEP delivery service in Rio de janeiro in the context of the COVID-19 pandemic. At the initial teleconsultation, individuals undergoe HIV rapid testing and are assessed by phone for PrEP related procedures. Individuals receive a digital prescription to retrieve a 120-day PrEP supply plus two HIV self-test kits. Subsequent follow-up teleconsultations will be performed remotely by phone call, including instructions for the HIV self-test performance, which results are to be sent using a digital picture. Participants will attend the service only for PrEP refill. The use of telemedicine procedures is being effective to avoid PrEP shortage and reduce the time PrEP users spend at the service during the COVID-19 pandemic and social distancing recommendations.

BACKGROUND: We evaluated the prevalence of sexualized drug use (Chemsex) and its association with moderate/high risk for substance use disorders and HIV sexual risk behavior among men who have sex with men (MSM). METHODS: We conducted a cross-sectional web-based survey among MSM from Rio de Janeiro (Brazil). The Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) was used to screen people at moderate/high-risk for substance use disorders. Individuals found to be using substances in the prior three months were asked if they used before/during sex. Sexualized drug use was classified into: no sexualized drug use, sex using only alcohol (alcohol-sex), sex using only illicit drugs (drug-sex) and sex using alcohol and illicit drugs (alcohol-drug-sex). The questionnaire included questions about sociodemographic, HIV status/prevention and risk behavior. A multinomial regression model was performed to assess the factors associated with sexualized drug use. RESULTS: Overall, 1048 MSM completed the questionnaire; median age was 29 years. Prevalence of alcohol and illicit drug use in previous 3 months was 89 % and 49 %, respectively. Most MSM (64 %) reported sexualized drug use: 28 % alcohol-sex, 9 % drug-sex and 27 % alcohol-drug-sex. Median ASSIST scores were higher among those reporting sexualized drug use compared to no use. All HIV sexual risk behavior variables presented increasing prevalence across the outcome categories. In the adjusted multivariate model, having moderate/high-risk for substance use disorders were associated with sexualized drug use. CONCLUSIONS: MSM reporting sexualized drug use should receive brief intervention for substance use disorders and be evaluated for combination HIV prevention strategies including PrEP.
