RESUMO
BACKGROUND: Primary Health Care (PHC) is essential for effective, efficient, and more equitable health systems for all people, including those living with HIV/AIDS. This study evaluated the impact of the exposure to one of the largest community-based PHC programs in the world, the Brazilian Family Health Strategy (FHS), on AIDS incidence and mortality. METHODS AND FINDINGS: A retrospective cohort study carried out in Brazil from January 1, 2007 to December 31, 2015. We conducted an impact evaluation using a cohort of 3,435,068 ≥13 years low-income individuals who were members of the 100 Million Brazilians Cohort, linked to AIDS diagnoses and deaths registries. We evaluated the impact of FHS on AIDS incidence and mortality and compared outcomes between residents of municipalities with low or no FHS coverage (unexposed) with those in municipalities with 100% FHS coverage (exposed). We used multivariable Poisson regressions adjusted for all relevant municipal and individual-level demographic, socioeconomic, and contextual variables, and weighted with inverse probability of treatment weighting (IPTW). We also estimated the FHS impact by sex and age and performed a wide range of sensitivity and triangulation analyses; 100% FHS coverage was associated with lower AIDS incidence (rate ratio [RR]: 0.76, 95% CI: 0.68 to 0.84) and mortality (RR: 0.68, 95%CI: 0.56 to 0.82). FHS impact was similar between men and women, but was larger in people aged ≥35 years old both for incidence (RR: 0.62, 95% CI: 0.53 to 0.72) and mortality (RR: 0.56, 95% CI: 0.43 to 0.72). The absence of important confounding variables (e.g., sexual behavior) is a key limitation of this study. CONCLUSIONS: AIDS should be an avoidable outcome for most people living with HIV today and our study shows that FHS coverage could significantly reduce AIDS incidence and mortality among low-income populations in Brazil. Universal access to comprehensive healthcare through community-based PHC programs should be promoted to achieve the Sustainable Development Goals of ending AIDS by 2030.

BACKGROUND: The effective testing of sexually transmitted infections (STIs) requires sampling from potential infection sites. This study aimed to assess the choice, satisfaction, and performance of self-collected samples (SCS) from potential infection sites for STI testing among transgender women in Brazil. METHODS: TransOdara was a multicentric, cross-sectional STI prevalence study conducted in 5 Brazilian cities. Using respondent-driven sampling, 1317 transgender women 18 years or older were recruited. Participants completed interviewer-led questionnaires and provided swab samples from multiple sites (anorectal, oropharyngeal, genital) for Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and human papillomavirus (HPV) testing. Participants were given a choice of SCS or provider-collected samples (PCS) at each site. RESULTS: Most participants selected SCS for anorectal (74.9%; 95% confidence interval [CI], 72.4-77.3) and genital (72.7%; 95% CI, 70.2-75.1) sites, whereas fewer chose for oropharyngeal samples (49.8%; 95% CI, 47.0-52.6). For future testing, most participants expressed a preference for SCS for genital (72.2%; 95% CI, 69.5-74.7) and anorectal (70.2%; 95% CI, 67.6-72.7) sites. There was no significant difference in the positive test results for CT and NG between SCS and PCS at anorectal and oropharyngeal sites, or for HPV at anorectal and genital (penile or neovaginal) sites. CONCLUSIONS: This study demonstrated a high level of acceptability and usability of self-sampling for STI testing among transgender women. A preference for SCS was evident at the anorectal and genital sites, and the results of SCS were comparable to those of PCS. The findings suggest that multisite STI testing utilizing self-collection methods as a provided option can be effectively integrated into sexual health services for transgender women.

Many barriers to human immunodeficiency virus (HIV) testing among Black people exist. This study analysed the association between race/skin colour and lifetime HIV testing among adolescent men who have sex with men (AMSM) and transgender women (ATGW) in three Brazilian cities. This cross-sectional study was nested within the PrEP1519 cohort, a multicentre study of AMSM and ATGW aged 15-19 years in Belo Horizonte, Salvador, and São Paulo, Brazil. The outcome variable was the lifetime HIV testing (no or yes). The main exposure variable was self-reported race/skin colour as White and a unique Black group (composed of Pardo-mixed colour and Black, according to the Brazilian classification). Descriptive statistics and bivariate and multiple logistic regression analyses were conducted to estimate the adjusted odds ratios (ORs) and 95% confidence intervals (95% CIs) to determine the association between the main exposure and outcome, adjusted for covariates. White adolescents were tested more frequently than the unique Black group (64.0% vs. 53.7%, respectively; Ρ = 0.001). Multiple logistic regression analysis showed that the unique Black group of AMSM and ATGW had 26% (adjusted OR [aOR], 0.74; 95% CI, 0.55-0.98) and 38% (aOR, 0.62; 95% CI, 0.45-0.87) lower odds of being tested for HIV in a lifetime than Whites in model 1 and 2, respectively. Our findings highlight the role of racism in lifetime HIV testing among AMSM and ATGW. Therefore, an urgent need for advances exists in public policies to combat racism in Brazil.
RESUMEN: Existen numerosas barreras para la realización de las pruebas del virus de la inmunodeficiencia humana (VIH) entre la población negra. Este estudio analizó la asociación entre la raza/color de piel y haber realizado pruebas de VIH a lo largo de la vida entre hombres adolescentes que tienen sexo con hombres (AHSH) y mujeres transgénero (AMTG) en tres ciudades brasileñas. Este estudio transversal es parte de la cohorte PrEP1519, un estudio multicéntrico de AHSH y AMTG de 15 a 19 años en Belo Horizonte, Salvador y São Paulo, Brasil. La variable de resultado fue haber realizado la prueba del VIH a lo largo de la vida (no o sí). La variable de exposición principal fue la raza/color de piel autoinformada, categorizada como blanca y un grupo negro único (compuesto por color pardo/mixto y negro, según la clasificación brasileña). Se realizaron estadísticas descriptivas y análisis de regresión logística bivariada y multivariada para estimar los odds ratios (OR) ajustados y los intervalos de confianza del 95% (IC del 95%) con el fin de determinar la asociación entre la exposición principal y el resultado, ajustado por covariables. Los adolescentes blancos se hicieron la prueba del VIH con más frecuencia que el grupo negro único (64,0% frente a 53,7%, respectivamente; Ρ = 0,001). El análisis de regresión logística múltiple reveló que el grupo negro único de AHSH y AMTG tenía 26% (OR ajustado [aOR], 0,74; IC 95%, 0,550,98) y 38% (aOR, 0,62; IC 95%, 0,450,87) menores probabilidades de realizarse la prueba del VIH a lo largo de su vida que los blancos en los modelos 1 y 2, respectivamente. Nuestros hallazgos resaltan la influencia del racismo en la realización de pruebas de VIH a lo largo de la vida entre AHSH y AMTG. Por lo tanto, es urgente avanzar en la implementación de políticas públicas para combatir el racismo en Brasil.

This study aims to estimate the COVID-19 vaccine acceptance and hesitancy among people living with HIV (PLWHA). A search for observational studies was conducted in five databases and preprinted literature. Summary estimates were pooled using a random effects model and meta-regression. Of 150 identified studies, 31 were eligible (18,550 PLWHA). The weighted prevalence of COVID-19 vaccine hesitancy overall was 29.07% among PLWHA (95%CI = 24.33-34.32; I² = 98%,) and that of vaccine acceptance was 68.66% (95%CI = 62.25-74.43; I² = 98%). Higher hesitancy prevalence was identified in low/lower-middle income countries (35.05; 95% CI = 19.38-54.78). The heterogeneity was explained by the risk of bias, region, and year of data collection. The findings conclude that the COVID-19 vaccine hesitancy rate remains high, especially in low-income countries. Evidence-informed interventions aimed at increasing COVID-19 vaccine acceptance at the national and individual levels ought to be designed to increase COVID-19 vaccine acceptance among PLWHA.

BACKGROUND: Migration is common among transgender women (TGW), often driven by the desire to escape stigma, find acceptance, establish new connections, access body modifications, or enter new avenues of sex work. Given the heightened mobility of TGW, they are mostly vulnerable to human immunodeficiency virus (HIV) due to migration. This study aimed to evaluate the association between in-country migration and HIV infection among TGW in Northeast Brazil. METHODS: The DIVAS was a cross-sectional, multicity study investigating risk behaviors and sexually transmitted infections (STI) among TGW in 2016-2017. A total of 864 TGW were recruited through respondent-driven sampling from three capital cities in Northeast Brazil. Logistic regression estimating odds ratios (OR) and 95% confidence intervals (CI) was used to assess the relationship between in-country migration and HIV infection. RESULTS: The prevalence of HIV among TGW was 24.5%, 21.4% among those aged 18-34 and 36.1% among those ≥ 35 years old. In-country migration increased the odds of HIV infection among TGW aged 18-34 years (OR = 1.84; 95%CI:1.04-3.27) and even higher among those aged ≥ 35y old (OR = 3.08; 95%CI:1.18-8.04). CONCLUSIONS: These data reinforce the pressing need for public health policies that provide comprehensive access and strategies for demand creation for HIV/AIDS prevention and care for TGW who are already highly vulnerable to infection.

OBJECTIVE: To end the AIDS epidemic by 2030, despite the increasing poverty and inequalities, policies should be designed to deal with population heterogeneity and environmental changes. Bottom-up designs, such as the Agent-Based Model (ABM), can model these features, dealing with such complexity. HIV/AIDS has a complex dynamic of structural factors, risk behaviors, biomedical characteristics and interventions. All embedded in unequal, stigmatized and heterogeneous social structure. To understand how ABMs can model this complexity, we performed a scoping review of HIV applications, highlighting their potentialities. METHODS: We searched on PubMed, Web of Science, and Scopus repositories following the PRISMA extension for scoping reviews. Our inclusion criteria were HIV/AIDS studies with an ABM application. We identified the main articles using a local co-citation analysis and categorized the overall literature aims, (sub)populations, regions, and if the papers declared the use of ODD protocol and limitations. RESULTS: We found 154 articles. We identified eleven main papers, and discussed them using the overall category results. Most studies model Transmission Dynamics (37/154), about Men who have sex with Men (MSM) (41/154), or individuals living in the US or South Africa (84/154). Recent studies applied ABM to model PrEP interventions (17/154) and Racial Disparities (12/154). Only six papers declared the use of ODD Protocol (6/154), and 34/154 didn't mention the study limitations. CONCLUSIONS: While ABM is among the most sophisticated techniques available to model HIV/AIDS complexity. Their applications are still restricted to some realities. However, researchers are challenged to think about social structure due model characteristics, the inclusion of these features is still restricted to case-specific. Data and computational power availability can enhance this feature providing insightful results.

OBJECTIVE: To identify groups of transgender women and travestis (TGW) with specific patterns of gender-based discrimination (GBD) and analyze the factors associated with GBD. METHODS: A cross-sectional study was conducted with TGW recruited through respondent-driven sampling in five Brazilian cities (2019-2021). Latent class analysis was used to characterize GBD (low, medium, and high) using 14 observable variables. Descriptive analysis was performed, and associations between predictor variables and GBD were estimated by adjusted odds ratios (aOR) using ordinal logistic regression. RESULTS: Out of a total of 1,317 TGW, 906 (68.8%) answered questions about GBD. Most were under 34 years old, single, and had a Brown race/skin color. GBD was classified as "low," "medium," and "high," with estimates of 41.7, 44.5, and 13.8%, respectively. Variables positively associated with higher intensity of GBD included living in Manaus compared to São Paulo, being ≤34 years old compared to >34, being homeless compared to living in one's own house or rented apartment, not having legally changed one's name compared to those who had, and reporting physical or sexual violence compared to those who did not report. Variables negatively associated with higher intensity of GBD included having a Brown or Asian race/skin color compared to White and a monthly income ≥1 minimum wage compared to ³1. CONCLUSION: A high proportion of GBD was observed in Brazilian TGW, with this outcome associated with more vulnerable sociodemographic characteristics and a history of violence.

OBJECTIVE: To investigate the prior testing for HIV, syphilis, hepatitis B (HBV), and hepatitis C (HCV) among transgender women and travestis (TGW) in five Brazilian cities and identify factors associated with each of these previous tests. METHODS: This is a cross-sectional study with the recruitment of TGW through respondent-driven sampling (TransOdara Study). The investigated outcome variable was prior testing for HIV, syphilis, HBV, and HCV in the last 12 months. The association between sociodemographic and behavioral factors with the outcome was analyzed using a binomial logistic regression with mixed effects. Adjusted odds ratios (aOR) and 95% confidence intervals (CI95%) were estimated. RESULTS: The proportions of individuals with prior testing in the past year were as follows: 56.3% for HIV, 58.0% for syphilis, 42.1% for HBV, and 44.7% for HCV. Negative associations with prior testing were observed for individuals aged 35 years or older, whereas positive associations were found for those with high school education, those who experienced verbal or psychological violence in the last 12 months, and those who had commercial or casual partners in the last 6 months. CONCLUSION: There was low frequency of testing in the 12 months preceding the study for HIV, syphilis, HBV, and HCV compared to the guidelines established by the Ministry of Health. Expanding access to and engagement with healthcare and prevention services for TGW is an essential strategy in reducing the transmission chain of HIV and other sexually transmitted infections (STIs).

BACKGROUND: As new and improved antigen-detecting rapid diagnostic tests for SARS-CoV-2 infection (Ag-RDT) continue to be developed, assessing their diagnostic performance is necessary to increase test options with accurate and rapid diagnostic capacity especially in resource-constrained settings. This study aimed to assess the performance of two Ag-RDTs in a population-based study. METHODS: We conducted a diagnostic accuracy study in neighborhoods with high socioeconomic vulnerability in Salvador-Brazil, including individuals aged ≥12 years old who attended primary health services, between July and December 2022, with COVID-19 symptoms or who had been in contact with a confirmed case. Two Ag-RDTs were compared in parallel using reverse transcription polymerase chain reaction (RT-PCR) as reference standard, the PanbioTM COVID-19 Ag test (Abbott®) and Immuno-Rapid COVID-19 Ag (WAMA Diagnostic®). Sensitivity, specificity, positive (PPV) and negative predictive values (NPV) were calculated. RESULTS: For the Abbott test the sensitivity was 52.7% (95% CI: 44.3% - 61.0%), specificity 100% (95% CI: 98.7% - 100%), PPV 100% (95% CI: 95.4% - 100%) and NPV 80.4% (95% CI: 75.9% - 84.4%). For the WAMA test, the sensitivity was 53.4% (95% CI: 45.0% - 61.6%), specificity 100% (95% CI: 98.7% - 100%), PPV 100% (95% CI: 95.4% - 100%) and NPV 80.7% (95% CI: 76.2% - 84.6%). Sensitivity for the group with Cycle Threshold (CT) <24 was 82.3% (95%CI: 72.1-90.0, n = 83) for PanbioTM COVID-19 Ag test and 87.3% (95%CI: 77.9-93.8, n = 83) for Immuno-Rapid COVID-19 Ag test. CONCLUSION: Sensitivity for both Ag-RDT was lower than reported by manufacturers. In the stratified analysis, sensitivity was higher among those with lower CT values <24. Specificity was high for both rapid antigen tests. Both Ag-RDT showed to be useful for rapid diagnostic of potential cases of COVID-19. Negative results must be assessed carefully according to clinical and epidemiological information.

This study aimed to analyze the challenges in demand creation for participation in an HIV pre-exposure prophylaxis (PrEP) project in two Brazilian capitals. This qualitative study was conducted with men who have sex with men and transgender women aged 15 to 19 years who lived in two Brazilian state capitals. For this analysis, 27 semi-structured interviews carried out from 2019 to 2020 were evaluated by reflexive thematic content analysis. For participants, PrEP demand creation was essential for their interaction, mediation, bonding, and attachment and proved effective for PrEP acceptability and adherence. Adolescents' narratives showed that the strategies promoted HIV combination prevention, opened up opportunities for recruitment meetings, helped to negotiate with and convince individuals to use PrEP, strengthened peer education, and evoked a feeling of "being with" and "walking together" despite the challenges. Face-to-face or online interactions using social technologies played a crucial role in recruiting adolescents for the project, expanding knowledge on PrEP and other combination prevention strategies and access to health services and self-care.

OBJECTIVE: To estimate the prevalence and factors associated with the detection of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) in transgender women and travestis in five Brazilian capitals. METHODS: Data were obtained from a cross-sectional study conducted between 2019 and 2021, with participants recruited through Respondent Driven Sampling in São Paulo, Campo Grande, Manaus, Porto Alegre and Salvador. Detection of CT and NG was analyzed at three collection sites (anorectal, oropharyngeal and urethral). Mixed logistic regression models were employed to identify associated factors. RESULTS: A total of 1,297 recruited participants provided biological material to detect these infections. The prevalences of CT, NG and coinfection were 11.5%, 13.3% and 3.6%, respectively. Independent associations with CT infections included past (OR=1.73; 95%CI 1.02-2.95), current (OR=2.13; 95%CI 1.23-3.69), and part-time sex work (OR=2.75; 95%CI 1.60-4.75), as well as lifetime injectable drug use (OR=3.54; 95%CI 1.49-8.40). For NG, associations were observed with lifetime injectable drug use (OR=1.91; 95%CI 1.28-2.84) and sexual orientation, including heterosexual (OR=3.44; 95%CI 1.35-8.82), homosexual (OR=5.49; 95%CI 1.89-15.97), and bisexual (OR=3.21; 95%CI 1.06-9.68). Coinfection was associated with use of illicit drugs in the last 12 months (OR=2.34, 95%CI 1.10-5.00), and younger age was associated with all investigated outcomes. CONCLUSION: Estimated prevalences of CT, NG and co-infection were higher among transgender women and travestis compared to the general population, particularly among younger, individuals engaged in sex work and illicit drug use.

OBJECTIVE: The objective of the present study is to describe the sociodemographic and behavioral characteristics of a group of transgender women and travestis (TGW) with a history of incarceration and the institutional and social context of this experience in Brazil. METHODS: The analyzed data were derived from the TransOdara Study, a cross-sectional study conducted in five Brazilian capitals from December 2019 to July 2021. Participants were recruited using the Respondent-Driven Sampling (RDS) technique, in which, after an initial formative and exploratory stage, the first participants were identified; in turn, these participants recruited up to six other transgender women and travestis for the research. The study's outcome was the experience of incarceration throughout life, captured through the question: "Have you ever been arrested in your life?" RESULTS: A total of 1,245 TGW were interviewed, of which 20.3% (n=253) experienced incarceration. Incarceration was more frequent among those aged 33 to 42 years (35.6%), with lower level of education (45.5%, p<0.001), engaged in informal work (30.3%), without a partner (67.2%), and among those who reported illicit drug use (66.4%). The majority (60.9%) of TGW were incarcerated with cisgender men, and the most common reasons for imprisonment were drug trafficking (30.4%) followed by robbery (29.2%). Over a quarter of the interviewees (26.3%) experienced assault, and 13.8% reported experiencing sexual violence during incarceration. CONCLUSION: The results emphasize the high prevalence of incarceration among TGW. This incarceration takes place in male wards and in a context of high rates of physical and sexual violence.

The relationships between race, education, wealth, their intersections and AIDS morbidity/mortality were analyzed in retrospective cohort of 28.3 million individuals followed for 9 years (2007-2015). Together with several sensitivity analyses, a wide range of interactions on additive and multiplicative scales were estimated. Race, education, and wealth were each strongly associated with all of the AIDS-related outcomes, and the magnitude of the associations increased as intersections were included. A significantly higher risk of illness (aRR: 3.07, 95%CI:2.67-3.53) and death (aRR: 4.96, 95%CI:3.99-6.16) from AIDS was observed at the intersection of Black race, lower educational attainment, and less wealth. A higher case-fatality rate (aRR: 1.62, 95%CI:1.18-2.21) was also seen for the same intersectional group. Historically oppressed groups lying at the intersections of race, education, and wealth, had a considerably higher risk of illness and death from AIDS. AIDS-related interventions will require the implementation of comprehensive intersectoral policies that follow an intersectionality perspective.
RESUMO
The global economic downturn due to the COVID-19 pandemic, war in Ukraine, and worldwide inflation surge may have a profound impact on poverty-related infectious diseases, especially in low-and middle-income countries (LMICs). In this work, we developed mathematical models for HIV/AIDS and Tuberculosis (TB) in Brazil, one of the largest and most unequal LMICs, incorporating poverty rates and temporal dynamics to evaluate and forecast the impact of the increase in poverty due to the economic crisis, and estimate the mitigation effects of alternative poverty-reduction policies on the incidence and mortality from AIDS and TB up to 2030. Three main intervention scenarios were simulated-an economic crisis followed by the implementation of social protection policies with none, moderate, or strong coverage-evaluating the incidence and mortality from AIDS and TB. Without social protection policies to mitigate the impact of the economic crisis, the burden of HIV/AIDS and TB would be significantly larger over the next decade, being responsible in 2030 for an incidence 13% (95% CI 4-31%) and mortality 21% (95% CI 12-34%) higher for HIV/AIDS, and an incidence 16% (95% CI 10-25%) and mortality 22% (95% CI 15-31%) higher for TB, if compared with a scenario of moderate social protection. These differences would be significantly larger if compared with a scenario of strong social protection, resulting in more than 230,000 cases and 34,000 deaths from AIDS and TB averted over the next decade in Brazil. Using a comprehensive approach, that integrated economic forecasting with mathematical and epidemiological models, we were able to show the importance of implementing robust social protection policies to avert a significant increase in incidence and mortality from AIDS and TB during the current global economic downturn.

Living with extremely low-income is an important risk factor for HIV/AIDS and can be mitigated by conditional cash transfers. Using a cohort of 22.7 million low-income individuals during 9 years, we evaluated the effects of the world's largest conditional cash transfer, the Programa Bolsa Família, on HIV/AIDS-related outcomes. Exposure to Programa Bolsa Família was associated with reduced AIDS incidence by 41% (RR:0.59; 95%CI:0.57-0.61), mortality by 39% (RR:0.61; 95%CI:0.57-0.64), and case fatality rates by 25% (RR:0.75; 95%CI:0.66-0.85) in the cohort, and Programa Bolsa Família effects were considerably stronger among individuals of extremely low-income [reduction of 55% for incidence (RR:0.45, 95% CI:0.42-0.47), 54% mortality (RR:0.46, 95% CI:0.42-0.49), and 37% case-fatality (RR:0.63, 95% CI:0.51 -0.76)], decreasing gradually until having no effect in individuals with higher incomes. Similar effects were observed on HIV notification. Programa Bolsa Família impact was also stronger among women and adolescents. Several sensitivity and triangulation analyses demonstrated the robustness of the results. Conditional cash transfers can significantly reduce AIDS morbidity and mortality in extremely vulnerable populations and should be considered an essential intervention to achieve AIDS-related sustainable development goals by 2030.

OBJECTIVE: To estimate the prevalence and factors associated with hepatitis A, B, and C in transgender women and travestis's networks, in 5 regions of Brazil. METHODS: This cross-sectional study includedtransgender women and travestis in five Brazilian capitals (Campo Grande, Manaus, Porto Alegre, Salvador, and São Paulo), between December/2019 and July/2021. All samples were subjected to detection of serological markers of hepatitis virus A (HAV), B (HBV), and C (HCV) infections through rapid tests and chemiluminescent microparticle immunoassays. Positive samples in the screening tests were submitted to detect HBV DNA and HCV-RNA by real-time PCR and genotyped by Sanger sequencing. RESULTS: Analysis of 1,317 samples showed network prevalence rates of 69.1%, 25.1%, and 1.5% for HAV, HBV, and HCV exposure, respectively. A high susceptibility rate to HBV infection (35.7%) and low prevalence of vaccine response markers (40%) were also observed. Age greater than 26 years, self-declared black/brown skin color, having only primary education, history of incarceration, and use of a condom in the last sexual intercourse with a casual partner were associated with total anti-HAV. Exposure to HBV was associated with age greater than 26 years, self-declared black/brown, history of being a sex worker, and incarceration. Age > 37 years, history of sexual abuse, and frequent alcohol consumption were associated with hepatitis C infection. CONCLUSION: The highest prevalence of HAV in this population was found in the North and Northeast regions, and the prevalence found was higher than that in the general population, suggesting greater vulnerability. The prevalence of HCV infection in our study was similar to that observed in the general population.

Abstract: This study aimed to analyze the challenges in demand creation for participation in an HIV pre-exposure prophylaxis (PrEP) project in two Brazilian capitals. This qualitative study was conducted with men who have sex with men and transgender women aged 15 to 19 years who lived in two Brazilian state capitals. For this analysis, 27 semi-structured interviews carried out from 2019 to 2020 were evaluated by reflexive thematic content analysis. For participants, PrEP demand creation was essential for their interaction, mediation, bonding, and attachment and proved effective for PrEP acceptability and adherence. Adolescents' narratives showed that the strategies promoted HIV combination prevention, opened up opportunities for recruitment meetings, helped to negotiate with and convince individuals to use PrEP, strengthened peer education, and evoked a feeling of "being with" and "walking together" despite the challenges. Face-to-face or online interactions using social technologies played a crucial role in recruiting adolescents for the project, expanding knowledge on PrEP and other combination prevention strategies and access to health services and self-care.
Resumo: Este estudo analisou desafios na criação de demanda para participação em um projeto de profilaxia pré-exposição (PrEP) ao HIV em duas capitais brasileiras. Trata-se de um estudo qualitativo realizado com homens que fazem sexo com homens e mulheres transgênero de 15 a 19 anos residentes de duas capitais brasileiras. Para esta análise, foram avaliadas 27 entrevistas semiestruturadas realizadas entre 2019 e 2020 com análise temática de conteúdo reflexiva. Para os participantes, a criação de demanda por PrEP foi essencial para o processo de interação, mediação, vínculo e apego e mostrou-se eficaz para a aceitabilidade e adesão à PrEP. As narrativas dos adolescentes mostraram que as estratégias promoveram a prevenção combinada do HIV, abriram oportunidades para reuniões de recrutamento, ajudaram a negociar e convencer os indivíduos a usar a PrEP, fortaleceram a educação entre pares e evocaram um sentimento de "estar com" e "caminhar juntos", apesar dos desafios. As interações, sejam presenciais ou online, com o uso de tecnologias sociais, desempenharam um papel crucial no recrutamento de adolescentes para o projeto, na ampliação do conhecimento sobre PrEP e demais estratégias combinadas de prevenção, e no acesso a serviços de saúde e autocuidado.

RESUMO
Adolescent men who have sex with men (AMSM) are at a heightened vulnerability for human immunodeficiency virus (HIV). This study aimed to estimate the prevalence of HIV and associated individual, social, and programmatic factors among AMSM in Salvador, Bahia State, Brazil. This is a cross-sectional study which analyzed baseline data from the PrEP1519 cohort in Salvador. Descriptive, bivariate, and multivariate analyses were conducted using the dimensions of vulnerability to HIV as hierarchical levels of analysis. Logistic regression models were used to estimate the odds ratios (OR) of the association between predictor variables and HIV infection. The prevalence of HIV infection among the 288 AMSM recruited to the project was 5.9% (95%CI: 3.7-9.3). Adjusted analysis showed a statistically significant association between self-identifying as a sex worker (OR = 3.74, 95%CI: 1.03-13.60) and HIV infection. Other associations with borderline statistical significance were the use of application programs to find sexual partners (OR = 3.30, 95%CI: 0.98-11.04), low schooling level (OR = 3.59, 95%CI: 0.96-13.41), failing to be hired or being dismissed from a job because of sexual orientation (OR = 2.88, 95%CI: 0.89-9.28), and not using health services as a usual source of care (OR = 3.14, 95%CI: 0.97-10.17). We found a high HIV prevalence among AMSM in Salvador. Furthermore, our study found that individual, social, and programmatic factors were associated with HIV infection among these AMSM. We recommend intensifying HIV combined-prevention activities for AMSM.
Homens adolescentes que fazem sexo com homens (AHSH) apresentam vulnerabilidade aumentada ao HIV. O estudo teve como objetivo estimar a prevalência de HIV e fatores individuais, sociais e programáticos entre AHSH em Salvador, Bahia, Brasil. O estudo transversal foi baseado na análise dos dados da linha de base da coorte PrEP1519 em Salvador. Foram realizadas análises descritivas, bivariadas e multivariadas, usando as dimensões de vulnerabilidade ao HIV como níveis analíticos hierárquicos. Foram usados modelos de regressão logística para estimar as razões de chances (OR) da associação entre as variáveis preditoras e a infecção pelo HIV. A prevalência de infecção pelo HIV entre os 288 AHSH recrutados pelo projeto foi de 5,9% (IC95%: 3,7-9,3). A análise ajustada mostrou uma associação estatisticamente significativa entre a autoidentificação como profissional do sexo (OR = 3,74, IC95%: 1,03-13,60) e a infecção pelo HIV. Outras associações com significância estatística limítrofe foram: uso de aplicativos para achar parceiros sexuais (OR = 3,30, IC95%: 0,98-11,04), menor escolaridade (OR = 3,59, IC95%: 0,96-13,41), história de não ter sido contratado ou de ter sido demitido em função da orientação sexual (OR = 2,88, IC95%: 0,89-9,28) e falta de uso de serviços de saúde como fonte usual de cuidados (OR = 3,14, IC95%: 0,97-10,17). Foi encontrada uma alta prevalência de HIV entre AHSH em Salvador. Além disso, o estudo mostrou que fatores encontrados nas dimensões individual, social e programática estiveram associados à infecção pelo HIV entre esses AHSH. Recomendamos a intensificação das atividades de prevenção combinada entre AHSH.
Los hombres adolescentes que tienen sexo con hombres (AHSH) sufren más vulnerabilidad ante el VIH. El objetivo de este estudio fue estimar la prevalencia de VIH y los factores asociados individuales, sociales, y programáticos asociados entre AHSH en Salvador, Bahia, Brasil. Se trata de un estudio transversal, basado en el análisis de los datos de referencia de la cohorte PrEP1519 en Salvador. Se realizaron análisis descriptivos, bivariados, y multivariados usando las dimensiones de vulnerabilidad respecto al VIH, como los niveles jerárquicos de análisis. Los modelos de regresión logística se usaron para estimar las odds ratios (OR) de la asociación entre las variables predictoras y la infección por VIH. La prevalencia de infección por VIH entre los 288 AHSH reclutados para el proyecto fue 5,9% (IC95%: 3,7-9,3). El análisis ajustado reveló una asociación estadísticamente significativa entre autoidentificarse como un trabajador sexual (OR = 3,74, IC95%: 1,03-13,60) y la infección por VIH. Otras asociaciones con una significación estadística marginal fueron: uso de apps para encontrar pareja sexual (OR = 3,30, IC95%: 0,98-11,04), menos años de educación (OR = 3,59, IC95%: 0,96-13,41), no estar contratado o ser despedido de un trabajo debido a la orientación sexual (OR = 2,88, IC95%: 0,89-9,28), y no usar los servicios de salud como recurso habitual de atención sanitaria (OR = 3,14, IC95%: 0,97-10,17). Se identificó una alta prevalencia de VIH entre AHSH en Salvador. Asimismo, nuestro estudio halló que los factores desde una perspectiva individual, dimensión social, y dimensión programática estuvieron asociados con una infección por VIH entre AHSH. Recomendamos que se intensifiquen las actividades combinadas de prevención contra el VIH para AHSH.
RESUMO
At the end of 2017, Brazil adopted HIV pre-exposure prophylaxis (PrEP) as part of a combination prevention strategy for the most at-risk populations. However, Brazil does not have specific guidelines for PrEP use among adolescents aged < 18 years. Therefore, researchers from different health disciplines conducted PrEP1519, the first PrEP demonstration cohort study, ongoing in three Brazilian cities - Salvador, Belo Horizonte, and São Paulo - among adolescent men who have sex with men and transgender women, aged 15-19 years. This study aims to evaluate the effectiveness of PrEP in real-world settings. Quantitative and qualitative methods were integrated to obtain data on PrEP acceptability, uptake, use, and adherence. Moreover, comprehensive services and friendly environments were implemented in the PrEP1519 clinics. This study aims to describe the collaborative efforts of interdisciplinary practices in the development of the PrEP1519 study. The articulation of researchers from different institutions and areas is challenging; but it also allows for a broader outlook on questions regarding the direction of the research, while enriching the decisions needed to be taken during the interactions and negotiations among the different individuals, including the youth team and participants. Furthermore, it reflects on the communication process between cultures and languages considering the trans-epistemic arena of knowledge production about HIV, sexually transmitted infections, PrEP, and other combination prevention strategies for adolescents.
No final de 2017, Brasil adotou a profilaxia pré-exposição do HIV (PrEP) como parte de uma estratégia de prevenção combinada para as populações com maior risco de infecção. Entretanto, o país não dispõe de diretrizes específicas para o uso da PrEP entre adolescentes abaixo de 18 anos de idade. Assim, pesquisadores de diferentes disciplinas de saúde realizaram o PrEP1519, o primeiro estudo de coorte de demonstração da PrEP, atualmente em andamento em três cidades brasileiras - Salvador, Belo Horizonte e São Paulo - entre homens adolescentes que fazem sexo com homens e mulheres transgênero, entre 15 e 19 anos de idade. O estudo busca avaliar a efetividade da PrEP em contextos da vida real. Foram integrados métodos quantitativos e qualitativos para obter dados sobre a aceitabilidade, adoção, uso e adesão à PrEP. Além disso, foram implementados serviços integrados e ambientes acolhedores nas clínicas PrEP1519. O estudo busca descrever os esforços colaborativos das práticas interdisciplinares no desenvolvimento do estudo PrEP1519. A articulação de pesquisadores de diferentes instituições e áreas representa um desafio, mas permite um olhar mais abrangente sobre questões relativas à direção da pesquisa, ao mesmo tempo em que enriquece as decisões necessárias durante as interações e negociações entre diferentes indivíduos, inclusive a equipe de jovens e os participantes. Além disso, reflete o processo de comunicação entre culturas e linguagens, considerando a arena trans-epistêmica da produção de conhecimento sobre HIV, infecções sexualmente transmissíveis, PrEP e outras estratégias de prevenção combinada para adolescentes.
A finales de 2017, Brasil adoptó la profilaxis previa a la exposición al VIH (PrEP) como parte de una estrategia de prevención combinada para las poblaciones de mayor riesgo. Sin embargo, Brasil no tiene directrices específicas para el uso de la PrEP entre los adolescentes < 18 años. Por lo tanto, investigadores de diferentes disciplinas sanitarias llevaron a cabo el PrEP1519, el primer estudio de cohorte de demostración de la PrEP, en curso en tres ciudades brasileñas -Salvador, Belo Horizonte y São Paulo- entre hombres adolescentes que tienen relaciones con hombres y mujeres transexuales, de entre 15 y 19 años. El objetivo de este estudio es evaluar la eficacia de la PPrE en entornos reales. Se integraron métodos cuantitativos y cualitativos para obtener datos sobre la aceptabilidad, la aceptación, el uso y la adherencia de la PrEP. Además, se implementaron servicios integrales y entornos amigables en las clínicas de PrEP1519. Este estudio pretende describir los esfuerzos de colaboración de las prácticas interdisciplinarias en el desarrollo del estudio PrEP1519. La articulación de investigadores de diferentes instituciones y áreas supone un reto; pero también permite ampliar la visión de las cuestiones relativas a la dirección de la investigación, a la vez que enriquece las decisiones que debían tomarse durante las interacciones y negociaciones entre los diferentes individuos, incluyendo el equipo de jóvenes y los participantes. Además, reflexiona sobre el proceso de comunicación entre culturas y lenguas teniendo en cuenta el ámbito trans-epistémico de la producción de conocimiento sobre el VIH, las infecciones de transmisión sexual, la PrEP y otras estrategias de prevención combinada para adolescentes.
