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.

ABSTRACT OBJECTIVE: To understand the perceptions and experiences of transsexual and travesti women and non-binary or gender-fluid people (TGWT+) in health services where they took pre-exposure prophylaxis (PrEP) in the periods before and during the pandemic, focusing on the resignification in the relationship with services and the continuity of HIV prevention via PrEP. METHODS: Qualitative research and analysis of empirical material generated in the context of broader studies were conducted. A total of 45 semi-structured interviews were conducted with TGWT+ PrEP users in the city of São Paulo and analyzed using iterative thematic content analysis. RESULTS: The TGWT+ interviewees gave new meanings to their struggles, daily lives and ways of caring for their health and played a central role within them. With its particularities, the COVID-19 pandemic became one more event among all the others that TGWT+ face daily. Alongside the COVID-19 pandemic, the TGWT+ were faced with the HIV epidemic, but with the possibility of prevention via PrEP. CONCLUSION: Based on a situated and conscious perspective, more explicit in the context of the health crisis, the TGWT+ intertwined conscious actions and care practices in dialog with health services. Further research on these groups from a spatiotemporal dynamic situated in specific contexts of meaning production would make it possible to advance prevention and care strategies, especially in times of health crisis.

RESUMO OBJETIVO: Compreender as percepções e experiências de mulheres transexuais, travestis e pessoas não binárias ou de gênero fluido (MTrT+) em serviços de saúde que fazem segmento de profilaxia pré-exposição sexual (PrEP), antes e durante o contexto de pandemia, quanto às ressignificações na relação com os serviços e à continuidade da prevenção ao HIV por meio da PrEP. MÉTODOS: Investigação qualitativa e análise de material empírico produzido no âmbito de estudos mais amplos. Realizaram-se 45 entrevistas semiestruturadas com MTrT+ usuárias da PrEP da cidade de São Paulo, aplicando-se posteriormente a análise de conteúdo temática iterativa. RESULTADOS: As MTrT+ entrevistadas, com relação à pandemia de covid-19; protagonizam e ressignificam suas próprias lutas, seus cotidianos e suas formas de cuidar da saúde. Com suas particularidades, a pandemia se torna um acontecimento a mais dentre todos os demais que as MTrT+ enfrentam quotidianamente. Paralelamente, transitam pela epidemia de HIV, mas com a possibilidade de se prevenir por meio da PrEP. CONCLUSÃO: Por uma perspectiva situada e consciente, mais explícita no contexto da crise sanitária, as MTrT+ entrelaçam ações conscientes e práticas de cuidado em diálogo com os serviços de saúde. Aprofundar as investigações sobre esses grupos, a partir de uma dinâmica espaço-temporal situada em contextos específicos de produção de sentido, possibilita avançar em estratégias de prevenção e cuidado, especialmente em momentos de crise sanitárias.

ABSTRACT OBJECTIVE: Viral hepatitis and sexually transmitted infections disproportionally affect men who have sex with men (MSM) and transgender women (TGW). However, only a few studies have evaluated the prevalence of hepatitis in these populations, especially in youths and adolescents. This study aimed to estimate the prevalence of biomarkers for hepatitis A, B, and C among young and adolescent MSM and TGW in three Brazilian municipalities. METHODS: Baseline data were collected from a combination of HIV prevention cohort of young and adolescent MSM (AMSM) and TGW (ATGW) aged 15-19 years in three Brazilian municipalities. A social behavioral questionnaire was applied, and immunoassays were performed to detect antibodies against hepatitis A (anti- HAV IgG and IgM), hepatitis B (anti-HBc and anti-HBs), and hepatitis C virus (anti-HCV); testing for the active hepatitis B marker, HBsAg, was also performed. The prevalence of reactive tests and 95% confidence interval (CI) for proportions were measured. RESULTS: The prevalence of naturally or artificially acquired immunity for hepatitis A totaled 17.7% (95%CI: 15.4-20.4), whereas that of acute infection, 0.4% (95%CI: 0.2-1.2). For hepatitis B and C, prevalence rates totaled 2.8% (95%CI: 1.8-4.4) and 0.2% (95%CI: 0.1-1.1), respectively. About 25.7% (95%CI: 22.4-29.4) of participants were non-reactive for anti-HBc and reactive for anti-HBs, the latter being a vaccine marker for hepatitis B. CONCLUSIONS: The investigation of viral hepatitis biomarkers among vulnerable populations enables the early identification of infections, the provision of timely treatment, and an opportunity to point out the need to expand vaccination coverage.

ABSTRACT OBJECTIVE: To identify the factors associated with HIV self-testing (HIVST) uptake among adolescent men who have sex with men (AMSM) and adolescent transgender women (ATGW) before and during the COVID-19 pandemic. METHODS: A cross-sectional HIVST uptake study was conducted among AMSM and ATGW. Peer educators and health professionals began providing HIVST in February 2019. The outcome was the HIVST uptake before and during the COVID-19 pandemic. The association between each predictor and outcome in each period was analyzed using simple and multiple logistic regressions, estimating odds ratios, and their respective 95% confidence intervals. RESULTS: The uptake was 229/510 (44.9%) and 382/1,075 (35.5%) before and during the pandemic. During the pre-pandemic period, HIVST uptake was higher in participants who reported receptive anal sex. During the pandemic, uptake was lower in participants with a steady sexual partner and higher in those with frequent oral sex with a steady partner in the previous three months. Before and during the pandemic, HIVST uptake was lower in ATGW and higher in those aged 18–19 years and in participants who lived alone. CONCLUSIONS: Uptake decreased during the pandemic. Sexual behavioral factors associated with HIVST uptake changed during the COVID-19 pandemic, showing the fluid dynamics of sexuality in AMSM and ATGW during this period. HIV programs can optimize the implementation of HIVST among adolescents and young people by incorporating effective and differentiated service delivery models to increase HIV testing uptake and to reach undiagnosed individuals effectively.

ABSTRACT OBJECTIVE: To evaluate whether adolescents from sexual minorities who initiated pre-exposure prophylaxis (PrEP) in community-based organizations (COs) are more socially and HIV-vulnerable compared with their counterparts from a conventional health service. In addition, to evaluate whether these adolescents had more timely access to prophylaxis METHODS: A PrEP demonstration study was conducted in the city of São Paulo in two COs, located in the center (CO-center) and the outskirts (CO-outskirts), and a conventional HIV testing service (CTA-center). Between 2020 and 2022, cisgender male adolescents who have sex with men (aMSM), transgender and gender diverse adolescents (aTTrans) aged 15 to 19 years, HIV-negative, with higher-risk practices for HIV were eligible for PrEP. Indicators of timely access and vulnerabilities of adolescents initiating PrEP in COs were analyzed using CTA-center as a reference and multinomial logistic regression. RESULTS: 608 adolescents initiated PrEP in COs and CTA-center. Adolescents from COs were associated with a shorter time to PrEP initiation (1–7 days; CO-outskirts: ORa = 2.91; 95%CI 1.22–6.92; CO-center: ORa = 1.91; 95%CI 1.10–3.31); and a lower housing Human Development Index (HDI) (CO-center: ORa = 0.97; 95%CI 0.94–1.00; CO-outskirts: ORa = 0.82; 95%CI 0.78–0.86). In CO-outskirts, there was an increased chance of adolescents being younger (ORa = 3.06; 95%CI 1.63–5.75) and living closer to the service (ORa = 0.82; 95%CI 0.78–0.86, mean 7.8 km). While adolescents from the CO-center were associated with greater prior knowledge of PrEP (ORa = 2.01; 95%CI 1.10–3.91) and high-risk perception (ORa = 2.02; 95%CI 1.18–3.44), adolescents from the COs were not associated with higher-risk sexual practices and situations of vulnerability to HIV. CONCLUSION: The provision of PrEP in the COs facilitated access for vulnerable adolescents and may contribute to reducing inequities.

RESUMO OBJETIVO: Avaliar se adolescentes de minorias sexuais que iniciaram a profilaxia pré-exposição sexual (PrEP) em organizações comunitárias (OC) apresentam maior vulnerabilidade social e ao HIV em comparação com adolescentes em PrEP de um serviço de saúde convencional. Além disso, avaliar se esses adolescentes tiveram um acesso mais oportuno à profilaxia. MÉTODOS: Estudo demonstrativo da efetividade de PrEP, realizado na cidade de São Paulo, em duas OC, localizadas no centro (OC-centro) e na periferia (OC-periferia), e em um serviço convencional de testagem para o HIV (CTA-centro). Foram elegíveis para PrEP, entre 2020 e 2022, adolescentes homens cisgêneros que fazem sexo com homens (aHSH), travestis, mulheres transexuais e pessoas transfemininas (aTTrans), de 15 a 19 anos, HIV-negativos e com práticas de maior risco para o HIV. Indicadores de acesso oportuno e de vulnerabilidades dos adolescentes iniciando PrEP nas OC foram analisados, tendo por referência o CTA-centro e empregando regressão logística multinomial. RESULTADOS: 608 adolescentes iniciaram PrEP nas OC e CTA-Centro. Adolescentes das OC estiveram associados a um menor tempo de início de PrEP (1–7 dias; OC-periferia: ORa = 2,91; IC95% 1,22–6,92; OC-centro: ORa = 1,91; IC95% 1,10–3,31); e a um menor IDH de moradia (OC-centro: ORa = 0,97; IC95% 0,94–1,00; OC-periferia: ORa = 0,82; IC95% 0,78–0,86). Na OC-periferia houve aumento na chance de os adolescentes serem mais jovens (ORa = 3,06; IC95% 1,63–5,75) e morarem mais próximos ao serviço (ORa = 0,82; IC95% 0,78–0,86, média 7,8 km). Enquanto adolescentes da OC-centro estiveram associados ao maior conhecimento prévio de PrEP (ORa = 2,01; IC95% 1,10–3,91) e a alta percepção de risco (ORa = 2,02; IC95% 1,18–3,44). Não estiveram associadas aos adolescentes das OC as práticas sexuais de maior risco e as situações de vulnerabilidade ao HIV. CONCLUSÕES: A oferta de PrEP nas OC facilitou o acesso de adolescentes vulnerabilizados e pode contribuir para reduzir inequidades.

ABSTRACT OBJECTIVE: To analyze the impact of intersecting systems of oppression on the continuum of PrEP care among adolescent gays, bisexuals, and other men who have sex with men (aGBMSM), and to examine how health professionals (HP) identify and address these challenges to provide sexual health care and HIV prevention. METHODS: This qualitative exploratory study was part of a cohort research project involving aGBMSM, travesties, and transgender women (aTrTW) using PrEP. Data analyzed consisted of 16 interviews with aGBMSM and eight with health professionals (HPs) in São Paulo study site. The methodological and theoretical framework for the interactive categorization of thematic analysis was based on an intersectional approach. RESULTS: The knowledge of aGBMSM about PrEP was influenced by the adverse effects of systems of oppression, particularly among Black adolescents, who acquired knowledge in a less technical manner compared to White adolescents. Most professionals recognized oppression and its impact on the PrEP care continuum (PrEPCC), especially noting the presence of racism. However, few articulated how different social markers compound barriers to the success of the PrEPCC. CONCLUSION: Social oppression affects the success of the PrEP care continuum (PrEPCC) in multiple ways. Health professionals (HPs) play a crucial role in mitigating and not perpetuating these negative experiences within health services, as well as in PrEP access, use, and adherence.

RESUMO OBJETIVO: Analisar os impactos dos sistemas de opressão intersectados no continuum do cuidado de profilaxia pré-exposição sexual (CCPrEP) entre gays, bissexuais e outros homens que fazem sexo com homens (aGBHSH) e como estes são identificados e tratados por profissionais de saúde (PS), visando o cuidado à saúde sexual e prevenção do HIV. MÉTODOS: Estudo de investigação qualitativa integrado a uma pesquisa de coorte com aGBHSH e mulheres transexuais e travestis (aMTrT) em uso de PrEP. Foram analisados dados produzidos na cidade de São Paulo, integrando 16 entrevistas com aGBHSH e oito com PS. O referencial teórico metodológico se orientou pela categorização interativa de análise temática com enquadramento interseccional. RESULTADOS: Os conhecimentos sobre PrEP dos aGBHSH são afetados pelos efeitos negativos dos sistemas de opressão, sobretudo entre adolescentes negros que adquirem conhecimento de forma menos técnica quando comparados aos brancos. A maioria dos profissionais enxerga as opressões e as suas consequências, e confere protagonismo ao racismo, mas poucos articulam os diferentes marcadores sociais que potencializam barreiras para o sucesso do CCPrEP. CONCLUSÕES: As opressões sociais impactam o sucesso do CCPrEP de diferentes maneiras. Os PS são centrais para mitigação e não propagação dessas experiências negativas dentro do serviço de saúde e no acesso, uso e adesão à PrEP.

ABSTRACT OBJECTIVE: This study aims to analyze the knowledge about the HIV event-driven pre-exposure prophylaxis (event-driven PrEP) scheme and the perception of its potential use among young men who have sex with men (MSM), travestis, and transgender women (TrTW) who were followed up in the cohort. METHODS: This qualitative study included 50 interviews with participants from the municipalities of Salvador and São Paulo, aged 15 to 19 years, who made daily use of PrEP or other preventive methods. They were addressed by different demand creation strategies. The in-depth interviews covered topics such as sexual practices, event-driven PrEP knowledge, acceptability, and motivations for its use. A two-stage thematic analysis was carried out on Nvivo, version 12. RESULTS: Most participants were unaware of event-driven PrEP, and many questioned its effectiveness and safety when receiving information about it. However, on learning about the program, many young people saw advantages, such as not having to take daily medication and the possibility of using it only at times of greater risk. Participants also found barriers to using event-driven PrEP, such as the unpredictability of sexual relations and the difficulty in administering dosages in this modality. CONCLUSION: Limited knowledge and experiences with daily oral PrEP influenced interest in event-driven PrEP, which highlights the need for information strategies that enable young MSM and TrTW to read about event-driven PrEP.

ABSTRACT OBJECTIVE: To understand the perceptions and experiences of transsexual and travesti women and non-binary or gender-fluid people (TGWT+) in health services where they took pre-exposure prophylaxis (PrEP) in the periods before and during the pandemic, focusing on the resignification in the relationship with services and the continuity of HIV prevention via PrEP. METHODS: Qualitative research and analysis of empirical material generated in the context of broader studies were conducted. A total of 45 semi-structured interviews were conducted with TGWT+ PrEP users in the city of São Paulo and analyzed using iterative thematic content analysis. RESULTS: The TGWT+ interviewees gave new meanings to their struggles, daily lives and ways of caring for their health and played a central role within them. With its particularities, the COVID-19 pandemic became one more event among all the others that TGWT+ face daily. Alongside the COVID-19 pandemic, the TGWT+ were faced with the HIV epidemic, but with the possibility of prevention via PrEP. CONCLUSION: Based on a situated and conscious perspective, more explicit in the context of the health crisis, the TGWT+ intertwined conscious actions and care practices in dialog with health services. Further research on these groups from a spatiotemporal dynamic situated in specific contexts of meaning production would make it possible to advance prevention and care strategies, especially in times of health crisis.

RESUMO OBJETIVO: Compreender as percepções e experiências de mulheres transexuais, travestis e pessoas não binárias ou de gênero fluido (MTrT+) em serviços de saúde que fazem segmento de profilaxia pré-exposição sexual (PrEP), antes e durante o contexto de pandemia, quanto às ressignificações na relação com os serviços e à continuidade da prevenção ao HIV por meio da PrEP. MÉTODOS: Investigação qualitativa e análise de material empírico produzido no âmbito de estudos mais amplos. Realizaram-se 45 entrevistas semiestruturadas com MTrT+ usuárias da PrEP da cidade de São Paulo, aplicando-se posteriormente a análise de conteúdo temática iterativa. RESULTADOS: As MTrT+ entrevistadas, com relação à pandemia de covid-19; protagonizam e ressignificam suas próprias lutas, seus cotidianos e suas formas de cuidar da saúde. Com suas particularidades, a pandemia se torna um acontecimento a mais dentre todos os demais que as MTrT+ enfrentam quotidianamente. Paralelamente, transitam pela epidemia de HIV, mas com a possibilidade de se prevenir por meio da PrEP. CONCLUSÃO: Por uma perspectiva situada e consciente, mais explícita no contexto da crise sanitária, as MTrT+ entrelaçam ações conscientes e práticas de cuidado em diálogo com os serviços de saúde. Aprofundar as investigações sobre esses grupos, a partir de uma dinâmica espaço-temporal situada em contextos específicos de produção de sentido, possibilita avançar em estratégias de prevenção e cuidado, especialmente em momentos de crise sanitárias.

ABSTRACT OBJECTIVE: To analyze the factors that increase the practice of condomless anal sex (CAS) among adolescent men who have sex with men (AMSM) and adolescent travestis and transgender women (ATGW) in three Brazilian state capitals. METHODS: PrEP1519 is a prospective, multicenter cohort study demonstrating the effectiveness of human immunodeficiency virus (HIV) pre-exposure prophylaxis (PrEP) among AMSM and ATGW aged from 15 to 19 years in three Brazilian state capitals. The analyses were performed with baseline cohort data, including 1,418 adolescents enrolled from 2019 to 2021. The outcome studied was CAS in the last six months, and the potentially associated factors were sociodemographic, behavioral, healthcare, and history of violence and discrimination. Descriptive, bivariate, and multivariate analyses were conducted. Adjusted prevalence ratios (aPRs) and 95% confidence intervals (95%CI) were estimated. RESULTS: Most of the participants were AMSM (91.5%), aged 18 to 19 years (75.9%), Black (40.5%), with secondary or higher education in progress (92.7%), with CAS during the first sexual intercourse (54.2%), sexual initiation before the age of 14 (43.4%), and history of group sex (24.6%) and transactional sex (14.6%). The prevalence of CAS in the last six months was 80.6% (95%CI 78.5%-82.6%). Adolescents who reported condomless first sexual intercourse (aPR: 1.18; 95%CI 1.10-1.25), use of psychoactive substances (aPR: 1.09; 95%CI 1.03-1.16), and transactional sex (aPR: 1.11; 95%CI 1.04-1.20) had a higher prevalence of CAS in the last six months. We also found that those aged 15 to 17 years had a higher prevalence of CAS than those aged 18 to 19 (aPR: 1.07; 95%CI 0.99-1.13). CONCLUSIONS: The prevalence of CAS was high among AMSM and ATGW, being associated with practices that may increase the risk of sexually transmitted infections (STIs). Therefore, it is recommended to strengthen sexual health programs for young people that address the issue of sexuality and STI prevention, as well as to expand access to preventive methods, such as condoms and PrEP.

RESUMO OBJETIVO: Analisar os fatores que aumentam a prática de sexo anal sem preservativo (SASP) entre adolescentes homens que fazem sexo com homens (aHSH) e travestis mulheres trans (aTrMT) em três capitais brasileiras. MÉTODOS: PrEP1519 é uma coorte prospectiva, multicêntrica, de demonstração da efetividade da profilaxia pré-exposição (PrEP) ao HIV entre aHSH e aTrMT, com idade entre 15 e 19 anos, em três capitais brasileiras. As análises foram realizadas com dados da linha de base da coorte, com a inclusão de 1.418 adolescentes inscritos de 2019 a 2021. O desfecho estudado foi SASP nos últimos seis meses, e os potenciais fatores associados foram sociodemográficos, comportamentais, de assistência à saúde e histórico de violência e discriminação. Foi realizada análise descritiva, bivariada e multivariada. Estimaram-se razões de prevalência ajustadas (RPa) e intervalos de confiança de 95% (IC95%). RESULTADOS: A maioria dos participantes era aHSH (91,5%), com idade de 18 a 19 anos (75,9%), pretos (40,5%), ensino médio e superior em andamento (92,7%), com relato de SASP na primeira relação sexual (54,2%), início da vida sexual antes dos 14 anos (43,4%) e história de sexo em grupo (24,6%) e de sexo transacional (14,6%). A prevalência de SASP nos últimos seis meses foi de 80,6% (IC95% 78,5%-82,6%). Adolescentes que relataram primeira relação sexual sem preservativo (RPa: 1,18; IC95% 1,10-1,25), consumo de substâncias psicoativas (RPa: 1,09; IC95% 1,03-1,16) e sexo transacional (RPa: 1,11; IC95% 1,04-1,20) tiveram maior prevalência de SASP nos últimos seis meses. Verificou-se também que aqueles com idade de 15 a 17 anos tiveram maior prevalência de SASP em comparação àqueles de 18 a 19 anos (RPa: 1,07; IC95% 0,99-1,13). CONCLUSÕES: A prevalência de SASP foi alta entre aHSH e aTrMT, bem como esteve associada a práticas que podem aumentar o risco de infecções sexualmente transmissíveis (IST). Assim, recomenda-se o fortalecimento de programas de saúde sexual para jovens que abordem o tema da sexualidade e prevenção de IST, tal como a ampliação do acesso a métodos preventivos, como preservativo e PrEP.

ABSTRACT OBJECTIVE: To identify recent HIV-1 infection and estimate HIV incidence among adolescent men who have sex with men (AMSM) and transgender women (ATGW) in Brazil. METHODS: From January to December 2020, a cross-sectional analysis was conducted with baseline data from the PrEP1519 study, an HIV pre-exposure prophylaxis (PrEP) demonstration cohort in Brazil among sexually active AMSM/ATGW aged 15-19. For enrollment, participants were screened with a fourth-generation HIV rapid test. The recent infection testing algorithm (RITA) included a recency assay in blood specimens, viral load, and CD4 cell count prior to antiretroviral treatment use. Among these participants, RITA-based HIV incidence was estimated using a mean duration of recency infection of 214 days and a false-recent rate of 0.02. RESULTS: Out of the 494 participants screened, 21 tested positive for HIV. Following RITA, five adolescents had a recent HIV infection, 14 had long-term infections, and two did not have blood specimens available. We classified these two participants as long-term infection cases due to CD4 cell counts and previous use of antiretroviral treatment. Among those who tested positive, all but one were AMSM (94.7%), 73.6% were aged 18-19, and 76.2% were non-White. The HIV prevalence was 4.2%, and the estimated HIV incidence was 1.7%. CONCLUSIONS: The estimated incidence highlights the need for targeted HIV prevention interventions, such as PrEP, for sexual minority adolescents. Integrating RITA into routine HIV testing services for this population provides valuable information on the current HIV epidemic. This strategy can aid in monitoring the effectiveness of prevention efforts and improving early entry to HIV care.

ABSTRACT OBJECTIVE: This study aims to analyze the knowledge about the HIV event-driven pre-exposure prophylaxis (event-driven PrEP) scheme and the perception of its potential use among young men who have sex with men (MSM), travestis, and transgender women (TrTW) who were followed up in the cohort. METHODS: This qualitative study included 50 interviews with participants from the municipalities of Salvador and São Paulo, aged 15 to 19 years, who made daily use of PrEP or other preventive methods. They were addressed by different demand creation strategies. The in-depth interviews covered topics such as sexual practices, event-driven PrEP knowledge, acceptability, and motivations for its use. A two-stage thematic analysis was carried out on Nvivo, version 12. RESULTS: Most participants were unaware of event-driven PrEP, and many questioned its effectiveness and safety when receiving information about it. However, on learning about the program, many young people saw advantages, such as not having to take daily medication and the possibility of using it only at times of greater risk. Participants also found barriers to using event-driven PrEP, such as the unpredictability of sexual relations and the difficulty in administering dosages in this modality. CONCLUSION: Limited knowledge and experiences with daily oral PrEP influenced interest in event-driven PrEP, which highlights the need for information strategies that enable young MSM and TrTW to read about event-driven PrEP. Young people valued the autonomy and management of preventive methods provides by this new modality, which is more in line with the dynamics of their sexual lives, but they face challenges in managing event-driven PrEP.

RESULTADOS: A maioria dos participantes desconhecia a PrEP-SD e muitos questionaram a sua efetividade e segurança ao receberem informações sobre ela. No entanto, ao conhecer o esquema, muitos jovens perceberam vantagens, como a não obrigatoriedade diária de medicamentos e a possibilidade de uso apenas em momentos de maior risco. Barreiras para o uso da PrEP-SD também foram identificadas pelos participantes, como a imprevisibilidade das relações sexuais e a dificuldade em administrar as dosagens nessa modalidade. CONCLUSÕES: O conhecimento limitado e as experiências com a PrEP oral diária influenciaram o interesse por ela, o que aponta a necessidade de estratégias informativas que permitam o letramento dos jovens HSH e TrMT na PrEP-SD. Os jovens valorizaram a autonomia e a gestão da prevenção mais alinhada à dinâmica de sua vida sexual propiciada pela nova modalidade, mas enfrentam desafios na gestão da PrEP-SD.

ABSTRACT OBJECTIVE: To evaluate whether adolescents from sexual minorities who initiated pre-exposure prophylaxis (PrEP) in community-based organizations (COs) are more socially and HIV-vulnerable compared with their counterparts from a conventional health service. In addition, to evaluate whether these adolescents had more timely access to prophylaxis METHODS: A PrEP demonstration study was conducted in the city of São Paulo in two COs, located in the center (CO-center) and the outskirts (CO-outskirts), and a conventional HIV testing service (CTA-center). Between 2020 and 2022, cisgender male adolescents who have sex with men (aMSM), transgender and gender diverse adolescents (aTTrans) aged 15 to 19 years, HIV-negative, with higher-risk practices for HIV were eligible for PrEP. Indicators of timely access and vulnerabilities of adolescents initiating PrEP in COs were analyzed using CTA-center as a reference and multinomial logistic regression. RESULTS: 608 adolescents initiated PrEP in COs and CTA-center. Adolescents from COs were associated with a shorter time to PrEP initiation (1–7 days; CO-outskirts: ORa = 2.91; 95%CI 1.22–6.92; CO-center: ORa = 1.91; 95%CI 1.10–3.31); and a lower housing Human Development Index (HDI) (CO-center: ORa = 0.97; 95%CI 0.94–1.00; CO-outskirts: ORa = 0.82; 95%CI 0.78–0.86). In CO-outskirts, there was an increased chance of adolescents being younger (ORa = 3.06; 95%CI 1.63–5.75) and living closer to the service (ORa = 0.82; 95%CI 0.78–0.86, mean 7.8 km). While adolescents from the CO-center were associated with greater prior knowledge of PrEP (ORa = 2.01; 95%CI 1.10–3.91) and high-risk perception (ORa = 2.02; 95%CI 1.18–3.44), adolescents from the COs were not associated with higher-risk sexual practices and situations of vulnerability to HIV. CONCLUSION: The provision of PrEP in the COs facilitated access for vulnerable adolescents and may contribute to reducing inequities.

RESUMO OBJETIVO: Avaliar se adolescentes de minorias sexuais que iniciaram a profilaxia pré-exposição sexual (PrEP) em organizações comunitárias (OC) apresentam maior vulnerabilidade social e ao HIV em comparação com adolescentes em PrEP de um serviço de saúde convencional. Além disso, avaliar se esses adolescentes tiveram um acesso mais oportuno à profilaxia. MÉTODOS: Estudo demonstrativo da efetividade de PrEP, realizado na cidade de São Paulo, em duas OC, localizadas no centro (OC-centro) e na periferia (OC-periferia), e em um serviço convencional de testagem para o HIV (CTA-centro). Foram elegíveis para PrEP, entre 2020 e 2022, adolescentes homens cisgêneros que fazem sexo com homens (aHSH), travestis, mulheres transexuais e pessoas transfemininas (aTTrans), de 15 a 19 anos, HIV-negativos e com práticas de maior risco para o HIV. Indicadores de acesso oportuno e de vulnerabilidades dos adolescentes iniciando PrEP nas OC foram analisados, tendo por referência o CTA-centro e empregando regressão logística multinomial. RESULTADOS: 608 adolescentes iniciaram PrEP nas OC e CTA-Centro. Adolescentes das OC estiveram associados a um menor tempo de início de PrEP (1–7 dias; OC-periferia: ORa = 2,91; IC95% 1,22–6,92; OC-centro: ORa = 1,91; IC95% 1,10–3,31); e a um menor IDH de moradia (OC-centro: ORa = 0,97; IC95% 0,94–1,00; OC-periferia: ORa = 0,82; IC95% 0,78–0,86). Na OC-periferia houve aumento na chance de os adolescentes serem mais jovens (ORa = 3,06; IC95% 1,63–5,75) e morarem mais próximos ao serviço (ORa = 0,82; IC95% 0,78–0,86, média 7,8 km). Enquanto adolescentes da OC-centro estiveram associados ao maior conhecimento prévio de PrEP (ORa = 2,01; IC95% 1,10–3,91) e a alta percepção de risco (ORa = 2,02; IC95% 1,18–3,44). Não estiveram associadas aos adolescentes das OC as práticas sexuais de maior risco e as situações de vulnerabilidade ao HIV. CONCLUSÕES: A oferta de PrEP nas OC facilitou o acesso de adolescentes vulnerabilizados e pode contribuir para reduzir inequidades.
