RESUMO

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.

RESUMO

Using baseline data from the PrEP1519 cohort, in this article we aimed to analyze: (i) the effectiveness of demand creation strategies (DCS) to enroll adolescent men who have sex with men (AMSM) and adolescent transgender women (ATGW) into an HIV combination prevention study in Brazil; (ii) the predictors of DCS for adolescents' enrollment; and (iii) the factors associated with DCS by comparing online and face-to-face strategies for enrollment. The DCS included peer recruitment (i.e., online and face-to-face) and referrals from health services and non-governmental organizations (NGOs). AMSM and ATGW who agreed to participate in the study could opt to enroll in either PrEP (PrEP arm) or to use other prevention methods (non-PrEP arm). Bivariate and multivariate analyses were conducted and logistic regression odds ratios were estimated. The DCS reached 4529 AMSM and ATGW, the majority of which were derived online (73.8%). Of this total, 935 (20.6%) enrolled to participate (76.6% in PrEP arm and 23.4% in non-PrEP arm). The effectiveness of enrolling adolescents into both arms was greater via direct referrals (235/382 and 84/382, respectively) and face-to-face peer recruitment (139/670 and 35/670, respectively) than online (328/3342). We found that a combination under DCS was required for successful enrollment in PrEP, with online strategies majorly tending to enroll adolescents of a higher socioeconomic status. Our findings reinforce the need for DCS that actively reaches out to all adolescents at the greatest risk for HIV infection, irrespective of their socioeconomic status.

RESUMO

This study analyzes how the COVID-19 pandemic affected sexual behavior and use of HIV prevention methods among young transgender women (YTGW) and young gay, bisexual and other men who have sex with men (YGBMSM) participating in an HIV pre-exposure prophylaxis (PrEP) demonstration study in Brazil. Online interviews with 39 participants aged 15-22 years old were conducted between September and November 2020 and analyzed based on social constructionism and human rights-based approaches to health. The pandemic disrupted interviewees' routines, negatively affecting their life conditions. Among those who did not have a steady partner, social distance measures led to temporary interruption of sexual encounters and increased sexting and solo sex. Conversely, for those who had a steady relationship such measures contributed to increasing sexual practices and intimacy. Participants who had sexual encounters during the pandemic reported having continued to use PrEP. However, home confinement with family, lack of privacy, loss of daily routines and changes in housing impaired PrEP adherence and attendance at follow-up consultations. These results highlight the importance of maintaining HIV-service delivery for these groups during a public health crisis, as well as to address the structural drivers of the epidemic with comprehensive HIV prevention policies and by ensuring access of YGBMSM and YTGW to social protection policies.

RESUMO

BACKGROUND: Brazil was strongly affected by the COVID-19 pandemic and the impact of the pandemic on sexual and gender minorities' youth remains unknown. This study aimed to estimate the seroprevalence of SARS-CoV-2 antibodies and associated factors among adolescent men who have sex with men (AMSM) and transgender women (ATGW) participants of a human immunodeficiency virus (HIV) pre-exposure prophylaxis cohort study (PrEP1519). METHODS: This is a cross-sectional design conducted between June and October 2020 in Salvador, Brazil. Serum samples were collected from AMSM and ATGW aged 16-21 years between June-October 2020. IgG and IgM anti-SARS-CoV-2 were detected by chemiluminescence immunoassay, and data were collected through a socio-behavioral questionnaire. RESULTS: Among the 137 participants, the seroprevalence of anti-SARS-CoV-2 IgG and IgM was 20.4%; 16.8% of the participants were positive for IgG, and 11.7% for IgM. In the multivariable analysis, the seroprevalence was two times higher among those who never wore masks (OR= 2.22; 95% CI: 1.08-4.57) and among those who believed that they could be easily cured of the disease (OR= 2.05; 95% CI: 1.05-4.01). CONCLUSIONS: The high seroprevalence of SARS-CoV-2 antibodies among gender and sexual minority youth seems to be informed by behaviors and attitudes that contrast with public health measures and the potential severity of the disease when vaccination was still not available.

RESUMO

BACKGROUND: HIV incidence rates have increased in adolescent men who have sex with men (AMSM) and adolescent transgender women (ATGW). Thus, it is essential to promote access to HIV prevention, including pre-exposure prophylaxis (PrEP), among these groups. Moreover, using artificial intelligence and online social platforms to create demand and access to health care services are essential tools for adolescents and youth. OBJECTIVE: This study aims to describe the participative process of developing a chatbot using artificial intelligence to create demand for PrEP use among AMSM and ATGW in Brazil. Furthermore, it analyzes the chatbot's acceptability, functionality, and usability and its results on the demand creation for PrEP. METHODS: The chatbot Amanda Selfie integrates the demand creation strategies based on social networks (DCSSNs) of the PrEP1519 study. She was conceived as a Black transgender woman and to function as a virtual peer educator. The development process occurred in 3 phases (conception, trial, and final version) and lasted 21 months. A mixed methodology was used for the evaluations. Qualitative approaches, such as in-depth adolescent interviews, were used to analyze acceptability and usability, while quantitative methods were used to analyze the functionality and result of the demand creation for PrEP based on interactions with Amanda and information from health care services about using PrEP. To evaluate Amanda's result on the demand creation for PrEP, we analyzed sociodemographic profiles of adolescents who interacted at least once with her and developed a cascade model containing the number of people at various stages between the first interaction and initiation of PrEP (PrEP uptake). These indicators were compared with other DCSs developed in the PrEP1519 study using chi-square tests and residual analysis (P=.05). RESULTS: Amanda Selfie was well accepted as a peer educator, clearly and objectively communicating on topics such as gender identity, sexual experiences, HIV, and PrEP. The chatbot proved appropriate for answering questions in an agile and confidential manner, using the language used by AMSM and ATGW and with a greater sense of security and less judgment. The interactions with Amanda Selfie combined with a health professional were well evaluated and improved the appointment scheduling. The chatbot interacted with most people (757/1239, 61.1%) reached by the DCSSNs. However, when compared with the other DCSSNs, Amanda was not efficient in identifying AMSM/ATGW (359/482, 74.5% vs 130/757, 17.2% of total interactions, respectively) and in PrEP uptake (90/359, 25.1% vs 19/130, 14.6%). The following profiles were associated (P<.001) with Amanda Selfie's demand creation, when compared with other DCS: ATGW and adolescents with higher levels of schooling and White skin color. CONCLUSIONS: Using a chatbot to create PrEP demand among AMSM and ATGW was well accepted, especially for ATGW with higher levels of schooling. A complimentary dialog with a health professional increased PrEP uptake, although it remained lower than the results of the other DCSSNs.

RESUMO

Female sex workers (FSW) are disproportionately affected by sexual violence (SV) and HIV. Social and structural barriers limit their access to post-exposure prophylaxis (PEP). Respondent-driven sampling survey in 12 Brazilian cities among 4188 FSW aimed to estimate the rates of SV and factors associated with access to PEP use among FSW who experienced SV. The prevalence of SV was 26.3% (1199). Of the 1199, 7.5% sought out healthcare and used PEP, 19% sought out healthcare, but did not use PEP, and 73.5% did not seek out healthcare after SV. Factors associated with PEP use included PEP awareness, participation in HIV/STI prevention workshops, and disclosure of FSW status in healthcare services. Although Brazil has a PEP program free of charge, it is not readily accessible, even for FSW who seek out healthcare. The development of effective strategies to link FSW to HIV preventive services is urgently needed.


RESUMEN: Mujeres trabajadoras sexuales (MTS) se ven afectadas de manera desproporcionada por la violencia sexual (VS) y el VIH. Las barreras sociales y estructurales limitan su acceso a la profilaxis posexposición (PEP). Encuesta de muestreo dirigida por encuestados en 12 ciudades brasileñas con 4188 MTS para estimar la prevalencia de VS y los factores asociados al uso de PEP entre MTS que experimentaron VS. La prevalencia de VS fue del 26.3% (1199). De essas, el 7.5% buscó atención médica y usó PEP, el 19% buscó atención médica pero no usó PEP y el 73.5% no buscó atención después del SV. Factores asociados con el uso de PEP: conciencia de PEP; participación en talleres educativos y divulgación del trabajo en los servicios de salud. Aunque Brasil tiene un programa de PEP gratuito, no es de fácil acceso. Es urgente el desarrollo de estrategias efectivas para vincular las MTS con servicios de prevención.

RESUMO

Cisgender female sex workers (CFSW) continue to face structural barriers to HIV prevention. We analyzed the acceptability of the oral HIV self-test (HIV-ST) among CFSW as part of a pragmatic trial on HIV prevention in Brazil. Data from in-depth interviews conducted with 12 women from diverse sex worker contexts and participant observation were analyzed using thematic analysis. CFSW valued autonomy in their workplaces and saw the HIV-ST as a possibility for self-care. Some feared clients' reactions, manager reprimands, and a positive result. HIV and sex work stigma largely drove self-care practices and perceived acceptability of the self-test. We argue that the autonomy offered by the self-test presents a paradox: increasing autonomy on the one hand while risking sidestepping structural dimensions of HIV vulnerability on the other. These nuances must be considered in interventions promoting the HIV-ST by considering the specificities of sex worker contexts, addressing stigma, and effectively involving CFSW and their organizations in intervention development.

RESUMO

BACKGROUND: Adolescent men who have sex with men (aMSM) and transgender women (aTGW) are affected disproportionately by human immunodeficiency virus (HIV) infection. Although new methods of pre-exposure prophylaxis (PrEP), such as long-acting injectable (LAI-PrEP), have been approved by the Food and Drug Administration, their acceptability among aMSM/aTGW is not well known. METHODS: Forty-eight semi-structured interviews were conducted to assess the knowledge and interest in LAI-PrEP among aMSM/aTGW enrolled in a daily oral PrEP cohort from two capital cities of Brazil since 2019. RESULTS: Previous knowledge of LAI-PrEP remains scarce, but the high interest regarding its use has been reported. Interest in the use of LAI-PrEP is associated with eliminating the burden of daily responsibility or the risk of missing the necessary medications, lowering the costs of this method, increasing confidentiality, and decreasing the frequency of visiting PrEP clinics. The reported barriers to uptake included fear of injection, doubts on its effectiveness, side effects, and greater dependence on a health provider. CONCLUSIONS: There is an urgent need to strengthen the preventive strategies against HIV infection among the youth, enhance their knowledge and those of healthcare providers, and offer safe and new options.

RESUMO

OBJECTIVES: There is a paucity of data on cardiovascular disease (CVD) among people living with HIV (PLHIV) in resource-limited countries. We assessed factors associated with CVD and the impact of prevalent CVD on all-cause mortality in PLHIV on antiretroviral therapy in Brazil. METHODS: Competing risk regression to assess factors associated with CVD and all-cause mortality in the HIV-Brazil Cohort Study between 2003 and 2014. RESULTS: Among 5614 patients, the rate of CVD was 3.5 (95% confidence interval [95% CI] 2.9-4.3) per 1000 person-years. CVD was associated with older age (adjusted hazard ratio [aHR] 6.4 for ≥55 years vs. <35 years, 95% CI: 2.5-16.3, P < 0.01), black race (aHR 1.8 vs. white race, 95% CI: 1.0-3.1, P = 0.04), past CVD (aHR 3.0 vs. no past CVD, 95% CI: 1.4-6.2, P < 0.01), hypertension (aHR 1.8 vs. no hypertension, 95% CI: 1.0-3.1, P = 0.04), high-grade dyslipidemia (aHR 9.3 vs. no high-grade dyslipidemia, 95% CI: 6.0-14.6, P < 0.01), ever smoking (aHR 2.4 vs. never, 95% CI: 1.2-5.0, P = 0.02) and low nadir CD4 cell count (aHR 1.8 for 100-250 cells/mm3 vs. >250 cells/mm3 , 95% CI: 1.0-3.2, P = 0.05). The rate of death was 16.6 (95% CI: 15.1-18.3) per 1000 person-years. Death was strongly associated with having had a past CVD event (aHR 1.7 vs. no past CVD event, 95% CI: 1.1-2.7, P = 0.01). CONCLUSIONS: Traditional and HIV-specific factors associated with CVD among PLHIV in Brazil are similar to those identified among PLHIV in high-income countries. PLHIV in Brazil with a history of CVD have a high risk of death. CVD care and treatment remain priorities for PLHIV in Brazil as this population ages and antiretroviral therapy use expands.


OBJECTIFS: Il existe peu de données sur les maladies cardiovasculaires (MCV) chez les personnes vivant avec le VIH (PVVIH) dans les pays à ressources limitées. Nous avons évalué les facteurs associés aux MCV et l'impact des MCV prévalentes sur la mortalité toutes causes confondues des PVVIH sous le traitement antirétroviral au Brésil. MÉTHODES: Régression des risques concurrente pour évaluer les facteurs associés aux MCV et à la mortalité toutes causes confondues dans l'étude de cohorte VIH-Brésil entre 2003 et 2014. RÉSULTATS: Parmi 5.614 patients, le taux de MCV était de 3,5 (intervalle de confiance à 95% [IC95%] 2,9-4,3) pour 1.000 personnes-années. Les MCV étaient associées à un âge plus avancé (rapport de risque ajusté [aHR] 6,4 chez les ≥55 ans versus chez les <35 ans, IC95%: 2,5-16,3 ; p <0,01), race noire (aHR: 1,8 versus race blanche, IC95%: 1,0-3,1 ; p = 0,04), MCV passée (aHR: 3,0 versus pas de MCV passée, IC95%: 1,4-6,2 ; p <0,01), hypertension (aHR: 1,8 versus pas d'hypertension, IC95%: 1,0-3,1 ; p = 0,04), dyslipidémie de grade élevé (aHR 9,3 versus absence de dyslipidémie de grade élevé, IC95%: 6,0-14,6 ; p <0,01), tabagisme (aHR 2,4 versus n'avoir jamais fumé, IC95%: 1,2-5,0 ; p = 0,02) et faible nombre de CD4 au nadir (aHR: 1,8 pour 100-250 cellules/mm3 versus >250 cellules/mm3 , IC95%: 1,0-3,2 ; p = 0,05). Le taux de décès était de 16,6 (IC95%: 15,1-18,3) pour 1.000 personnes-années. Le décès était fortement associé à un événement MCV antérieur (aHR: 1,7 versus aucun événement MCV antérieur, IC95%: 1,1-2,7 ; p = 0,01). CONCLUSIONS: Les facteurs traditionnels et spécifiques au VIH associés aux MCV chez les PVVIH au Brésil sont similaires à ceux identifiés chez les PVVIH dans les pays à revenu élevé. Les PVVIH au Brésil ayant des antécédents de MCV ont un risque élevé de décès. Les soins et le traitement des MCV restent des priorités pour les PVVIH au Brésil à mesure que cette population vieillit et que l'utilisation des thérapies antirétrovirales augmente.

RESUMO

BACKGROUND: Since March 2014, the quadrivalent HPV vaccine has been incorporated into the Brazilian Unified Health Care System and began to be offered, without direct costs, for girls from 9 to 13 years of age. Older female adolescents would have the option to be vaccinated at private health care system being responsible for the payment of HPV vaccine. The present study aimed to evaluate the coverage rates and predictors of HPV vaccination in Brazil among two groups of female adolescents: eligible and non-eligible for the HPV vaccination public program. METHODS: We used data from the 2015 Brazilian National Adolescent School-Based Health Survey, which involved a probabilistic sample of 5404 female adolescents students at public and private schools. Using a questionnaire, we gathered information on sociodemographic characteristics, sexual behavior, and respondent perception of parental supervision and have been vaccinated for HPV. Age-specific vaccination rates were analyzed in girls aged 9 to 13 at the time of public vaccination (eligible for public policy), as well among those 14 to 17 years old not eligible by the Ministry of Health for vaccination. We used Poisson regression models to investigate associated factors. RESULTS: HPV vaccine coverage was 83.5 and 21.8% among eligible and non-eligible populations, respectively. In both populations, the chance of being vaccinated decreased with older age. In the eligible population there is a greater chance of being vaccinated among ethnic group "pardas" but not with other indicators of socioeconomic status. In the non-eligible population, there was a clear association between higher vaccine coverage and greater maternal education and living with the mother. CONCLUSION: Our findings highlight the importance of public policies to minimize inequities in access to cancer prevention measures in vulnerable adolescents. A public policy of HPV vaccination for older female adolescents would increase coverage with possible reduction of HPV-related diseases in this group of women.

RESUMO

BACKGROUND: The HIV-Brazil Cohort Study (HIV-BCS) is a research primarily based on data collection from medical records of people living with HIV/AIDS in Brazil. The aim of this study was to present the validating design and results for the laboratory biomarkers viral load and CD4+ T-cell count from the HIV-Brazil Cohort Study. METHODS: A total of 8007 patients who were started cART from 2003 to 2013 were considered eligible for this study. Total follow-up time was 32,397 years. The median duration of follow-up was 3.51 years (interquartile range - IQR 1.63-6.13 years; maximum 11.51 years). We used secondary data from the Brazilian Laboratory Tests Control System (SISCEL). Incidence of lab testing rates per 100 person years (100 py) were used to compare the number of laboratory tests carried out among cohort sites considering different databases for CD4+ T-cell counts and HIV viral load assessments. Descriptive statistics including 95% confidence interval, Pearson correlation coefficient, Bland-Altman agreement analysis and kappa coefficient agreement were applied for analysis. RESULTS: A total of 80,302 CD4+ T-cell counts and 79,997 HIV viral load assessments were observed in HIV-BCS versus 94,083 CD4+ T-cell counts and 84,810 viral loads from the Brazilian Laboratory Tests Control System. The general CD4+ T-cell HIV-BCS testing rate was 247 per 100 py versus 290 per 100 py and the viral load HIV-BCS testing rate was 246 per 100 py versus 261 per 100 py. The general correlation observed for the lowest quantitative CD4+ T-cell count before cART was 0.970 (p < 0.001) and for the log of the highest viral load before cART was 0.971 (p < 0.001). The general agreement coefficient for categorized CD4+ T-cell count was 0.932 (p < 0.001) and for viral load was 0.996 (p < 0.001). CONCLUSIONS: The current study confirms that biomarkers CD4+ T-cell count and viral load from the HIV-BCS have a high correlation and agreement with data from SISCEL, rendering both databases reliable and useful for epidemiological studies on HIV care in Brazil.

RESUMO

In this study, we systematically examined the importance of human rights standards and principles for rights-based pre-exposure prophylaxis (PrEP) provision for marginalized adolescents. Nested within a demonstration study of PrEP provision to adolescent men who have sex with men, travestis, and transgender women, we carried out interviews in São Paulo, Brazil with 25 adolescents, eight health providers, and six workers involved in community-based demand creation. Analysis focused on participants' narratives about aspects of human rights within service delivery, including the availability, accessibility, acceptability, and quality of services; informed decision-making; nondiscrimination; and privacy and confidentiality. Clients and service providers highlighted the importance of availing a range of services beyond PrEP and described how community outreach and social media helped promote accessibility. Acceptability centered around clients feeling heard and respected. Health workers appreciated having time to build trusting relationships with clients to ensure quality of care and support informed decision-making. Nondiscrimination was valued by all, including using clients' chosen pronouns. Privacy and confidentiality were primary concerns for clients who were not "out" about their sexuality or PrEP use; to mitigate this, health workers sought to accommodate clients' preferred channels of communication. Rights-based PrEP services can help promote engagement and retention in PrEP services, particularly for marginalized populations.

RESUMO

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

HIV Pre-exposure prophylaxis (PrEP) is an effective prevention tool, but there are still few studies about PrEP uptake among adolescents. We aimed to analyze the PrEP uptake process and factors associated with daily oral PrEP initiation among adolescent men who have sex with men (aMSM) and transgender women (aTGW) in Brazil. Baseline data from the first demonstration PrEP cohort study among aMSM and aTGW 15-19 years old (yo) ongoing in three large Brazilian cities (PrEP1519). After completing informed consent procedures, participants were enrolled in the cohort from February/2019 to February/2021. A socio-behavioral questionnaire was applied. Factors associated with PrEP initiation were assessed using a logistic regression model with adjusted prevalence ratios (aPR) and 95% confidence intervals (95%CI). Among recruited participants, 174 (19,2%) were aged 15-17 yo and 734 (80,8%) 18-19 yo. The rate of PrEP initiation was 78.2% and 77.4% for 15-17 yo and 18-19 yo, respectively. Factors associated with PrEP initiation were: black or mixed race (aPR 2.31; 95%CI: 1.10-4.84) among the younger adolescents 15-17 yo; experienced violence and/or discrimination due to their sexual orientation or gender identity (aPR 1.21; 95%CI: 1.01-1.46); transactional sex (aPR 1.32; 95%CI: 1.04-1.68); and having had between 2 to 5 sexual partners in the previous three months (aPR 1.39; 95%CI: 1.15-1.68) among those 18-19 yo. Unprotected receptive anal intercourse in the previous six months was associated with PrEP initiation in both age groups (aPR 1.98; 95%CI: 1.02-3.85 and aPR 1.45; 95%CI: 1.19-1.76 among 15-17 yo and 18-19 yo, respectively). The biggest challenge to promoting PrEP use for aMSM and aTGW was in the first steps of the PrEP uptake process. Once they were linked to the PrEP clinic, initiation rates were high.

RESUMO

The United Nations has underscored the possibility of ending the HIV epidemic as a public health problem. However, an increase in the incidence among adolescents and youth has indicated a greater distance between HIV responses and the specificities of the new generations, which can maintain the epidemic for an extended period. Regards this matter, it is debated that the provision of a range of preventive methods, even if highly effective, and a conservatism that has internalized stigma within government policies, hinder the proper and essential dialogue between current preventive policies and the needs of the new generations. These generations are marked by a social representation of AIDS as a mild disease, by new gender and sexuality performances, and by the search for a more critical role in affective and sexual encounters, which includes frequent use of dating apps and substances. The hierarchy of the delivery of prevention methods is presented as a proposal for a new policy, prioritizing pre-exposure prophylaxis (PrEP) and addressing the social determinants of the HIV epidemic, including strategies to mitigate stigma. The importance of the participation of adolescents and youth in constructing the policy and the need for an intersectoral response are also reinforced.


A Organização das Nações Unidas tem destacado a possibilidade de eliminar a epidemia de HIV como um problema de saúde pública. Porém, um aumento da incidência em adolescentes e jovens tem indicado um maior distanciamento entre a resposta ao HIV e as especificidades próprias das novas gerações, que pode estender a epidemia por um longo período. Frente a isso, é discutido que a oferta de uma cesta universal de métodos preventivos, mesmo que altamente eficazes, e um conservadorismo que internalizou o estigma em políticas governamentais, inviabilizam o adequado e necessário diálogo entre as atuais políticas preventivas e as necessidades das novas gerações. Estas gerações que são marcadas por uma representação social da aids com menor gravidade; novas performances de gênero e de orientação sexual; e a busca de um maior protagonismo nas interações afetivas e sexuais, o que inclui o uso mais frequente de aplicativos de encontro de parcerias e de substâncias na cena de sexo. É apresentado como proposta de uma nova política a hierarquização da oferta de métodos preventivos, com a priorização da profilaxia pré-exposição (PrEP) e o enfrentamento dos determinantes sociais da epidemia do HIV, incluindo estratégias de redução do estigma. Reforça-se, ainda, a importância da participação de adolescentes e jovens na construção da política e a necessidade de uma resposta intersetorial.


Las Naciones Unidas señalan la posibilidad de eliminar la epidemia del VIH como un problema de salud pública. Sin embargo, un incremento de la incidencia de esta enfermedad en adolescentes y jóvenes muestra una mayor distancia entre la respuesta al VIH y las especificidades de las nuevas generaciones, lo que puede extender la epidemia durante un largo periodo. En este contexto, se discute que la oferta de una canasta universal de métodos preventivos, aunque altamente efectivos, y que un conservadurismo que interiorizó el estigma en las políticas gubernamentales hacen inviable un adecuado y necesario diálogo entre las políticas preventivas actuales y las necesidades de las nuevas generaciones. Estas generaciones están marcadas por una representación social del sida con menos gravedad, por nuevas actuaciones de género y orientación sexual y por la búsqueda de un mayor protagonismo en las interacciones afectivas y sexuales, que incluye el uso más frecuente de aplicaciones para encontrar parejas y de sustancias en la escena sexual. Se presenta como propuesta de una nueva política la priorización de la oferta de métodos preventivos, con la priorización de la profilaxis preexposición (PrEP) y la confrontación de los determinantes sociales de la epidemia del VIH, que incluyen estrategias para reducir el estigma. También refuerza la importancia de la participación de los adolescentes y jóvenes en la construcción de la política y la necesidad de una respuesta intersectorial.

RESUMO

PURPOSE: This study analyzed the sociodemographic and behavioral characteristics of adolescent men who have sex with men (aMSM) and transgender women (aTGW) initiating oral pre-exposure prophylaxis (PrEP) in human immunodeficiency virus (HIV) prevention clinics. METHODS: PrEP1519 is a prospective, multicenter, open-label PrEP demonstration cohort study of aMSM and aTGW aged 15-19 years living in three large Brazilian capital cities. For this analysis, we included adolescents who enrolled in PrEP1519 from February 2019 to August 2021. Adolescents who visited PrEP clinics were classified into four groups based on PrEP eligibility and on their decision to use PrEP: (1) ineligible for same-day PrEP initiation; (2) eligible for same-day PrEP initiation, initiated PrEP at first visit; (3) eligible for PrEP initiation, initiated PrEP after the first visit; and (4) eligible for same-day PrEP initiation but declined. The groups that were eligible for same-day PrEP initiation were compared using the Chi-square and Fisher's exact tests. RESULTS: Of the 1,254 adolescents enrolled in the PrEP1519 study, 61 (4.9%) were considered ineligible for same-day PrEP initiation. Of the 1,193 eligible for same-day PrEP initiation, 1,113 (93.3%) initiated PrEP [1,054 initiated PrEP in the first visit (88.3%) and 59 in subsequent visits (4.9%)] and 80 (6.7%) did not. Despite 90% of the PrEP decliners reporting a low risk of HIV infection, most reported condomless anal sex in the past six months (70%). DISCUSSION: Same-day PrEP initiation among aMSM and aTGW was high, highlighting that this strategy was important to promote PrEP initiation among adolescents with increased vulnerability to HIV in Brazil.

RESUMO

We aimed to understand the perspective and use of HIV prevention methods in context of the sexual practices of adolescent gay and bisexual men, travestis, and transgender women (TGW). In-depth interviews and focus group discussions were conducted with 22 adolescent gay and bisexual men, travestis, and TGW aged between 15 and 19 years in São Paulo, Brazil, as part of the formative research of the PrEP1519 study, an ongoing daily oral pre-exposure prophylaxis (PrEP) demonstration study among adolescents. Participants' knowledge repertoire about prevention methods and their experience with them concentrated on condoms, which were regarded as the most well-known, "compulsory" practice, whose use was an individual responsibility. Prior HIV/STI testing was reported by a few participants as a measure to decide to discontinue condom use in stable relationships, whereas seeking testing after condomless sex was an attempt to repair a "failure" in prevention. The importance of commercial sex was striking among TGW and travestis, in which condom use often depended on clients' decision, and drug use and risk of violence hindered decision-making and self-care. Adolescents showed little knowledge, frequent confusion, and no experience with post-exposure prophylaxis and PrEP. An incipient appropriation of the diversity of prevention methods and a rigid normativity about the use of condoms are key drivers in adolescents' perception and use of HIV prevention methods. Adolescents' risk management seems to be restricted in terms of their autonomy and ability to assess exposure across contexts, failing to include antiretroviral-based (ARV) methods, thus requiring tailored and context-sensitive strategies for an effective combination prevention approach.

RESUMO

The HIV epidemic has a disproportionate impact on adolescent and young men who have sex with men (AMSM) and transgender women and travestis (ATGW), with an increased HIV prevalence over the last 10 years. Violence affects the lives of these populations, undermining their ability to self-care and making them more vulnerable to HIV infection. In this study, we aimed to examine the association between different types of victimization by violence and discrimination and sexual health practices of these adolescent populations in steady and casual relationships. We conducted a cross-sectional study using baseline data from the cohort of PrEP1519 project. We used the mean score of sexual health practices as our outcome and the cumulative score of discrimination (within family, community, education, religious, online and public spaces) and violence (physical, sexual and intimate partner) as our exposure variable. We performed linear regression analyses to estimate the association between exposure and outcome. We found that 90% of AMSM and 95% of ATGW experienced at least one form of violence in the three months prior to this study and about 45% of ATGW suffered sexual violence during the same period. Experiencing discrimination within healthcare settings (from facilities or providers) was negatively associated with sexual health practices. Discrimination and violence negatively affect sexual health practices. HIV prevention and care of AMSM and ATGW people should involve listening to their experiences and addressing discrimination and violence in this population.

RESUMO

In view of the growing concern about the use of qualitative approach in health research, this article aims to analyze how the qualitative theoretical-methodological framework of HIV prevention is presented in empirical research. We conducted an integrative literature review with the following guiding questions: "How is the qualitative theoretical-methodological framework expressed in empirical research on HIV prevention?"; "What are the limits and potentials of the qualitative methodological designs employed?". In the qualitative methodological discussion, five dimensions guided the methodological course and the presentation of findings, from the analysis of the characterization of qualitative studies to the contextualization of the studies and the methodological approaches used, highlighting the use of semi-structured interviews with thematic content analysis. We also examined social categories and analytical references, drawing attention to the plurality of these theoretical-conceptual references and to the authors' polyphony, and identified the limits and potentials of qualitative research. This study focuses on a scientific topic that is related to a wide variety of social groups and analyzes how they are affected by it, examining issues related to social inequality and other analytical possibilities surrounding HIV prevention, and providing resources for a comprehensive methodological discussion. Hence, avoiding the risk of conducting qualitative research based on checklists that limit inventiveness and openness to different designs and forms of execution and analysis is as pivotal as ensuring that the research is consistent and detailed in publications.
