ABSTRACT 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.

RESUMO Objetivo: Estimar as prevalências e fatores associados com as hepatites A, B e C em mulheres trans e travestis em cinco regiões do Brasil. Métodos: Estudo transversal com mulheres trans e travestis em cinco capitais brasileiras (Campo Grande, Manaus, Porto Alegre, Salvador e São Paulo), entre dezembro/2019 e julho/2021. As amostras foram submetidas à detecção de marcadores das infecções pelos vírus das hepatites A (HAV), B (HBV) e C (HCV), utilizando-se testes rápidos e quimioluminescência. Amostras positivas foram submetidas à detecção de HBV-DNA e HCV-RNA por PCR em tempo real e genotipadas por sequenciamento de Sanger. Resultados: As análises de 1.317 amostras indicaram taxas de prevalências nas mulheres trans e travestis recrutadas de 69,1%, 24,4% e 1,5% para exposição ao HAV, HBV e HCV, respectivamente. Elevada taxa de suscetibilidade ao HBV (35,7%) e baixa prevalência do marcador vacinal (40,0%) foram observadas. Mostraram-se associadas à presença de anti-HAV: idade maior que 26 anos, autodeclarar-se preta-parda, ter apenas educação básica, história de encarceramento e uso de preservativo na última relação sexual com parceiro casual. Quanto à exposição ao HBV, foi associada a idade maior que 26 anos, cor da pele preto-parda, ter sido profissional do sexo e história de encarceramento. Idade maior de 37 anos, história de abuso sexual e consumo frequente de álcool foram associadas ao HCV. Conclusão: As maiores prevalências de HAV nessa população encontram-se nas regiões Norte e Nordeste. Com relação ao HBV, a prevalência encontrada foi superior à encontrada na população geral, sugerindo maior vulnerabilidade. A prevalência do HCV foi semelhante à encontrada na população geral.

ABSTRACT Objective To estimate the prevalence of concomitant substance consumption and analyze associated risk factors in a non-probabilistic sample of the Brazilian population of transgender women and travestis. Methods A cross-sectional study was conducted with recruitment via respondent-driven sampling. The sample included transgender women and travestis residing in São Paulo, Porto Alegre, Salvador, Manaus, and Campo Grande, aged 18 years or older, between 2019 and 2021. The outcome was the concomitant use of licit and illicit substances. The association between sociodemographic/behavioral factors and the outcome was analyzed through Poisson regression with mixed effects. Adjusted prevalence ratios (confidence interval of 95% — 95%CI) were estimated. Results The prevalence in the last 12 months of multiple substance use was 49.3%, of which 65.5% were alcohol, 52.9% tobacco, and 40.1% marijuana. Transgender women and travestis who use multiple substances face more violence (1.71; 95%CI 1.14–2.55), unemployment (1.58; 95%CI 1.05–2.37) and pervasive unstable work status (1.52; 95%CI 1.08–2.14), transactional sex (1.51; 95%CI 1.21–1.88) which can be their sole option to make a living, and are aged 18 to 24 years (1.37; 95%CI 1.14–1.65). Conclusion The use of multiple substances may be an attempt to cope with distress and marginalization. Substance use has been associated with multiple harms and medical conditions. Comprehensive management and care should be provided, as defined by the key principles of the Brazilian Unified Health System. Health care should be integrated into structural interventions. nonprobabilistic non probabilistic crosssectional cross sectional respondentdriven respondent driven sampling Paulo Alegre Salvador Manaus Grande 1 older 201 2021 sociodemographicbehavioral sociodemographic behavioral effects confidence 95 95CI CI estimated 493 49 3 49.3% 655 65 5 65.5 alcohol 529 52 9 52.9 tobacco 401 40 40.1 marijuana 1.71 171 71 (1.71 1.14–2.55, 114255 1.14–2.55 , 14 2 55 1.14–2.55) 1.58 158 58 (1.58 1.05–2.37 105237 05 37 1.52 152 (1.52 1.08–2.14, 108214 1.08–2.14 08 1.08–2.14) 1.51 151 51 (1.51 1.21–1.88 121188 21 88 living 1.37 137 (1.37 1.14–1.65. 114165 1.14–1.65 . 1.14–1.65) marginalization conditions provided System interventions 20 202 4 49.3 6 65. 52. 40. 1.7 17 7 (1.7 11425 1.14–2.5 1.5 15 (1.5 1.05–2.3 10523 0 10821 1.08–2.1 1.21–1.8 12118 8 1.3 13 (1.3 11416 1.14–1.6 49. 1.

RESUMO Objetivo Estimar a prevalência do consumo concomitante de substâncias e analisar fatores de risco associados em uma amostra não probabilística da população brasileira de mulheres trans e travestis. Métodos Estudo transversal, com recrutamento por meio da metodologia respondent-driven sampling. A amostra incluiu mulheres trans e travestis residentes em São Paulo, Porto Alegre, Salvador, Manaus e Campo Grande, maiores de 18 anos, entre 2019 e 2021. O desfecho foi o uso concomitante de substâncias lícitas e ilícitas. A associação entre fatores sociodemográficos/comportamentais e o desfecho foi analisada com regressão de Poisson com efeitos mistos, estimando-se razões de prevalência ajustadas (intervalo de confiança de 95% – IC95%). Resultados A prevalência nos últimos 12 meses de uso de múltiplas substâncias foi de 49,3%, sendo 65,5% álcool, 52,9% tabaco e 40,1% maconha. Mulheres trans e travestis que usam múltiplas substâncias enfrentam mais violência (1,71; IC95% 1,14–2,55), desemprego (1,58; IC95% 1,05–2,37) e trabalho instável (1,52; IC95% 1,08–2,14), sexo transacional (1,51; IC95% 1,21–1,88), que pode ser a única opção de sustento, e têm de 18 a 24 anos (1,37; IC95% 1,14–1,65). Conclusão O uso de múltiplas substâncias pode ser uma tentativa de lidar com o sofrimento e a marginalização. O uso de substâncias tem sido associado a múltiplos danos e condições médicas. Uma gestão integral e cuidados abrangentes devem ser providenciados, conforme definido pelos princípios-chave do Sistema Único de Saúde do Brasil. Os cuidados de saúde devem ser integrados em intervenções estruturais. transversal respondentdriven respondent driven sampling Paulo Alegre Salvador Grande 1 201 2021 ilícitas sociodemográficoscomportamentais sociodemográficos comportamentais mistos estimandose estimando se intervalo 95 IC95%.

ABSTRACT 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.

RESUMO Objetivo: Estimar as prevalências e os fatores associados à detecção de Chlamydia trachomatis (CT) e Neisseria gonorrhoeae (NG) em mulheres trans e travestis em cinco capitais brasileiras. Métodos: Os dados vieram de um estudo transversal, realizado entre 2019 e 2021, com pessoas recrutadas por RDS (respondent driven sampling) em São Paulo, Campo Grande, Manaus, Porto Alegre e Salvador. Analisou-se a detecção de CT e NG, em três sítios de coleta (anorretal, orofaríngeo e uretral). Para identificação dos fatores associados empregaram-se modelos logísticos com efeitos mistos. Resultados: Forneceram material biológico para detecção dessas infecções 1.297 participantes recrutadas. As prevalências de CT, NG e coinfecção foram, respectivamente, 11,5, 13,3 e 3,6%. Foram independentemente associados à detecção para CT: trabalho sexual no passado (odds ratio — OR=1,73; intervalos de confiança para 95% — IC95% 1,02–2,95), no momento atual (OR=2,13; IC95% 1,23–3,69) e como atividade parcial (OR=2,75; IC95% 1,60–4,75) e uso de drogas injetáveis na vida (OR=3,54; IC95% 1,49–8,40). Para NG: uso de drogas injetáveis na vida (OR=1,91; IC95% 1,28–2,84) e orientação sexual – heterossexuais (OR=3,44; IC95% 1,35–8,82), homossexuais (OR=5,49; IC95% 1,89–15,97) e bissexuais (OR=3,21; IC95% 1,06–9,68). Para coinfecção: uso de drogas nos últimos 12 meses (OR=2,34; IC95% 1,10–5,00). Ser mais jovem foi associada a todos os desfechos investigados. Conclusão: As prevalências estimadas de CT, NG e de coinfecção foram desproporcionalmente mais elevadas entre as mulheres trans e travestis se comparadas à população geral, especialmente entre as mais jovens, que exerciam trabalho sexual e faziam uso de drogas.

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.

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 Objetivou-se avaliar o desempenho produtivo e reprodutivo de ovinos da raça Santa Inês e mestiços da raça Dorper criados em sistema tradicional de produção durante a fase de amamentação na época seca do ano no semiárido paraibano. O experimento foi conduzido no Setor de Caprinovinocultura da Universidade Estadual da Paraíba/UEPB/Campus-IV, Catolé do Rocha/PB. Foram utilizadas 24 ovelhas multíparas, sendo 12 da raça Santa Inês e 12 mestiças da raça Dorper (87,5% Dorper + 12,5% Santa Inês) paridas com 30 ovinos jovens, sendo 10 machos e 20 fêmeas. O período experimental se iniciou no momento do parto e os dados foram coletados ao nascimento, aos 30, 60 e 90 dias de idade. Foi utilizada análise de variância para as ovelhas e para os cordeiros esquema fatorial 2 x 2 (dois grupos genéticos e dois sexos). Os cordeiros permaneceram com suas mães em piquetes durante o dia e à noite no aprisco, manejo tradicional da região. As ovelhas Santa Inês e mestiças Dorper produziram quantidades de leite semelhantes (P=0,8310) até os 60 dias de lactação. O grupo genético das ovelhas não influenciou os pesos vivos e escore de corporal ao parto, 30, 60 e 90 dias de lactação, como também a eficiência produtiva e peso total de crias desmamadas por ovelha. Os cordeiros e cordeiras Dorper apresentaram maiores pesos vivos (P=0,0349) e ganhos de peso (P=0,0403), por outro lado, o sexo dos ovinos jovens não influenciou o desempenho até os 90 dias de amamentação.

Abstract This study evaluated the productive and reproductive performances of Santa Inês sheep and their Dorper crossbreeds during the lactation period amidst the dry season in the semi-arid region of Paraíba, Brazil. Conducted at the experimental goat farm of the State University of Paraíba (UEPB), Campus IV, Catolé do Rocha, the investigation included a cohort of 24 ewes (12 Santa Inês and 12 Dorper crossbreeds [comprising 87.5% Dorper and 12.5% Santa Inês]) and 30 lambs (10 males and 20 females). Observations were recorded from birth and continued at 30-day intervals up to 90 days. Using a two-way ANOVA with a 2 x 2 factorial design (two genetic groups and two sexes), the study monitored both ewes and lambs. The animals adhered to traditional regional management, grazing in paddocks by day and secured in shelters by dusk. The study found that both Santa Inês and Dorper crossbred ewes produced similar quantities of milk (P=0.8310) for the first 60 days of lactation. There was no discernible effect of the ewes’ genetic backgrounds on their live weights, body condition scores at lambing, throughout the subsequent 30, 60, and 90 days of lactation, or on the overall productive efficiency and total weight of weaned lambs per ewe. In contrast, Dorper lambs demonstrated a higher weaning weight (P=0.0349) and greater weight gain (P=0.0403). The study also noted that the sex of the lambs did not notably influence their performance within the first 90 days of suckling. semiarid semi arid Brazil UEPB, UEPB , (UEPB) IV Rocha (1 1 comprising 875 87 5 87.5 125 12.5 Inês] 3 10 females. females . females) 30day 9 twoway way sexes, sexes sexes) management dusk P=0.8310 P08310 P 0 8310 (P=0.8310 6 weights lambing ewe contrast P=0.0349 P00349 0349 (P=0.0349 P=0.0403.

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.

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 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: O objetivo deste estudo é analisar o conhecimento sobre o esquema de Profilaxia Pré-Exposição ao HIV sob demanda (PrEP-SD) e a percepção do seu uso potencial entre jovens homens que fazem sexo com homens (HSH), travestis e mulheres trans (TrMT) em acompanhamento na coorte. MÉTODOS: O estudo qualitativo incluiu 50 entrevistas com participantes das cidades de Salvador e São Paulo, entre 15 e 19 anos, que estavam usando PrEP diária ou outros métodos preventivos. Eles foram abordados por meio de diferentes estratégias de criação de demanda. As entrevistas em profundidade abordaram temas como práticas sexuais, conhecimento sobre PrEP-SD, aceitabilidade e motivações para o uso. Foi realizada análise temática em duas fases usando o software Nvivo versão 12. 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: 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.

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 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.

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.

RESUMO OBJETIVO: Neste artigo, discutimos como a profilaxia pré-exposição (PrEP) e a carga viral indetectável=intransmissível (CVI=I) têm produzido reconfigurações nos contextos de encontros afetivo-sexuais de jovens gays/ homens que fazem sexo com homens (HSH) vivendo com HIV (JVHIV). MÉTODOS: Conduzimos entrevistas em profundidade com nove JVHIV, de 18 a 29 anos, oriundos de duas pesquisas realizadas em Salvador/Bahia, em 2019 e 2021. Focalizamos narrativas sobre acontecimentos inéditos na prevenção e no tratamento do HIV/aids, que têm permitido experiências de maior intimidade e segurança, mas também desafios e tensionamentos às relações afetivo-sexuais. RESULTADOS: Momentos distintos da experiência de viver com HIV revelam diferentes narrativas dos JVHIV com relação às novas biotecnologias de PrEP e CVI. Preocupações em torno de uma possível transmissão do HIV ou da obrigação de revelar a sorologia ficam mais destacadas entre jovens com o diagnóstico mais recente, enquanto aqueles com maior tempo de sorologia se colocam de forma mais confortável e confiante frente às novas tecnologias e seus efeitos significativos nos encontros sexuais, ainda que permaneçam controvérsias a respeito das consequências morais e comportamentais do uso delas. Alguns JVHIV reatualizam preocupações e trazem relatos sobre a continuidade do estigma em relação às pessoas vivendo com HIV. Outros JVHIV enfatizam os benefícios dos avanços biomédicos, com abertura para novas possibilidades interativas, inclusive sem uso da camisinha, sublinhando a existência de outras práticas, saberes, dinâmicas e formas de negociação do risco/cuidado, com tensionamentos no campo da própria sexualidade. CONCLUSÕES: Reiteramos a necessidade de retomada de políticas públicas no campo do HIV/aids para além das estratégias biomédicas, dando destaque às vulnerabilidades, à disseminação de informações sobre as novas tecnologias de prevenção e tratamento do HIV, ao respeito à autonomia das pessoas em suas escolhas preventivas e ao desenvolvimento de estratégias de enfrentamento aos estigmas associados ao HIV/aids.

ABSTRACT OBJECTIVE: This article discusses how Pre-Exposure Prophylaxis (PrEP) and the undetectable viral load=untransmissible (UVL=U) have produced reconfigurations in the contexts of affective-sexual encounters of young gay men/men who have sex with men (MSM) living with HIV (YLHIV). METHODS: In-depth interviews were conducted with nine YLHIV, aged 18 to 29, from two studies conducted in Salvador, Bahia, in 2019 and 2021. The narratives focused on unprecedented events in the prevention and treatment of HIV/AIDS, which have allowed experiences of greater intimacy and safety but also challenges and tensions in affective-sexual relationships. RESULTS: Different moments in the experience of living with HIV reveal different narratives of YLHIV concerning the new PrEP and UVL biotechnologies. Concerns surrounding possible HIV transmission or the obligation to reveal serology are more prominent among young people with the most recent diagnosis. In contrast, those with more extended serology experience are more comfortable and confident in the face of new technologies and their significant effects on sexual encounters. However, controversies remain regarding the moral and behavioral consequences of their use. Some YLHIV re-update concerns and bring reports about the continuity of stigma toward people living with HIV. Others emphasize the benefits of biomedical advances, opening up new interactive possibilities, including without the use of condoms, highlighting the existence of other practices, knowledge, dynamics, and ways of negotiating risk/care, with tensions in the field of sexuality itself. CONCLUSIONS: We reiterate the need to resume public policies in the field of HIV/AIDS beyond biomedical strategies, highlighting vulnerabilities, the dissemination of information about new HIV prevention and treatment technologies, respect for people’s autonomy in their preventive choices, and the development of strategies to combat the stigma associated with HIV/AIDS.

RESUMO Objetivo Investigar a prevalência do vírus da imunodeficiência humana (HIV) entre mulheres trans e travestis em cinco capitais no Brasil. Métodos TransOdara foi um estudo de corte transversal que avaliou comportamentos e a prevalência de infecções sexualmente transmissíveis (IST) entre mulheres trans e travestis em cinco capitais brasileiras, entre 2019 e 2021. Mulheres trans e travestis ≥18 anos foram recrutadas utilizando respondent-driven sampling, responderam a um questionário e fizeram testes rápidos para HIV e outras IST. O desfecho foi o resultado do teste rápido para HIV. Estimaram-se razões de prevalência ajustadas e intervalos de confiança de 95% por meio da regressão de Poisson com variância robusta. Resultados: No seu conjunto, esta população mostrou-se vulnerabilizada, com níveis elevados de moradia instável e no mercado de trabalho informal. Habitualmente, essas mulheres recorrem ao sexo comercial como sua atividade profissional principal. Metade delas receberam menos do que um salário mínimo, vivendo em condições desfavoráveis. A prevalência da infecção pelo HIV foi de 34.40%. No modelo final, as variáveis associadas com a prevalência do HIV foram: ter 31 anos ou mais, não estar estudando no momento da entrevista, estar desempregada e estar engajada em sexo comercial. Conclusão Foi identificada uma prevalência substancialmente elevada para o HIV entre as mulheres trans e travestis (em contraste com a prevalência baixa na população geral de mulheres brasileiras), sublinhando o contexto de vulnerabilidade desta população. Os achados indicam claramente a premência de intensificar e expandir o acesso à prevenção do HIV e da implementação de estratégias que interrompam o processo de discriminação vivenciado nos serviços de saúde e ofereçam serviços apropriados a esta população.

ABSTRACT Objective The aim of this study was to investigate the prevalence of human immunodeficiency virus (HIV) infection among transgender women and travestis and to analyze factors associated with HIV infection in Brazil. Methods TransOdara was a cross-sectional study on sexually transmitted infections among transgender women and travestis in five Brazilian cities between 2019 and 2021. Self-identified transgender women and travestis aged ≥18 years were recruited using respondent-driven sampling, completed an interviewer-led questionnaire, and provided samples to detect HIV. The outcome was the result of the rapid antigen testing for HIV. Adjusted prevalence ratios (aPR) and 95% confidence intervals (95% CI) were obtained using Poisson regression with robust variance. Results Overall, this population was found to be especially vulnerable, with high levels of unstable housing and engagement in informal work. They usually resort to transactional sex as their main working activity. Half of them earned less than the Brazilian minimum wage, which characterizes a poor population living in dire conditions. The overall HIV prevalence was 34.40%. In the final model, the variables associated with the HIV prevalence were as follows: to be 31 years old or older, not studying at the moment they were interviewed, to be unemployed, and engaged in lifetime transactional sex. Conclusion We found disproportionately high HIV prevalence among transgender women and travestis, compared with a low prevalence among respective segments of Brazil’s general population, which highlights the context of vulnerability in this population. The data point to the urgency for intensification and expansion of access to HIV prevention and strategies to stop discrimination in health care (among other services and contexts) and provide comprehensive services for this population.
