ABSTRACT Objective Sexually transmitted infections (STIs) disproportionately affect transgender women and travestis (TGW), who often lack access to healthcare due to stigma and discrimination. We describe the approach and methodology of a study investigating the prevalence of syphilis, HIV, hepatitis A, B, and C, Neisseria gonorrhoeae (NG), Chlamydia trachomatis (CT), and human papillomavirus (HPV) among TGW, as well as their knowledge and perceptions regarding syphilis, to better inform policies to curb STIs among this vulnerable population. Methods: TransOdara was a multicentric, cross-sectional study conducted among TGW in five capital cities from major Brazilian regions between December 2019 and July 2021. Self-identified transgender women and travestis aged >18 years were recruited using respondent-driven sampling after a qualitative formative phase, completed an interviewer-led questionnaire, were offered a physical examination, and were also asked to provide samples from multiple sites to detect various STIs, starting vaccination and treatment when indicated. Results: A total of 1,317 participants were recruited from the five study locations: Campo Grande (n=181, 13.7%), Manaus (n=340, 25.8%), Porto Alegre (n=192, 14.6%), Salvador (n=201, 15.3%), and São Paulo (n=403, 30.6%). The recruitment period varied at each study location due to logistic constraints imposed by the COVID-19 pandemic. Conclusion: Despite the enormous challenges posed by the co-occurrence of the COVID-19 pandemic and field work targeting a vulnerable, elusive, and scattered population, the TransOdara project has been effectively implemented. Caveats did not preclude 1,300 TGW from being interviewed and tested, amid a significant epidemic that disrupted health services and research projects in Brazil and worldwide.

RESUMO Objetivo As infecções sexualmente transmissíveis (IST) afetam desproporcionalmente as mulheres trans e travestis (MTT), que muitas vezes não têm acesso a cuidados de saúde devido ao estigma e à discriminação. Descrevemos a abordagem e a metodologia de um estudo que investigou a prevalência de sífilis, HIV, hepatite A, B e C, Neisseria gonorrhoeae (NG), Chlamydia trachomatis (CT) e papilomavírus humano (HPV) entre as MTT, bem como seu conhecimento e percepção sobre a sífilis, para melhor as políticas para redução de IST nessa população vulnerável. Métodos: TransOdara foi um estudo multicêntrico, transversal, realizado em cinco capitais das principais regiões brasileiras entre dezembro de 2019 e julho de 2021. Mulheres autoidentificadas como mulheres trans ou travestis, com idade >18 anos, foram recrutadas usando respondent-driven sampling, após uma fase de pesquisa formativa. Responderam a um questionário conduzido por entrevistadoras. Foi oferecida consulta médica, com exame físico, e solicitou-se que fornecessem amostras de vários locais para detectar as IST citadas. Quando indicado e consentido, foram iniciadas a vacinação e o tratamento. Resultados: Foram recrutadas 1.317 participantes nos cinco locais de estudo: Campo Grande (n=181, 13,7%), Manaus (n=340, 25,8%), Porto Alegre (n=192, 14,6%), Salvador (n= =201, 15,3%) e São Paulo (n=403, 30,6%). O período de recrutamento variou em cada local em razão de restrições logísticas impostas pela pandemia de COVID-19. Conclusão: Apesar dos enormes desafios colocados pela ocorrência simultânea da pandemia da COVID-19 e do trabalho de campo dirigido a uma população vulnerabilizada e dispersa, o projeto TransOdara foi eficazmente implementado. As adversidades não impediram que mais de 1.300 mulheres trans e travestis tenham sido entrevistadas e testadas em meio a uma epidemia de tal magnitude que perturbou os serviços de saúde e os projetos de pesquisa no Brasil e no mundo.

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.

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 Objective Determinar a aceitabilidade e os fatores associados à realização do exame físico para detecção de infecções sexualmente transmissíveis (IST) sintomáticas em mulheres trans e travestis no Brasil. Métodos: Foram utilizados dados do “TransOdara”, estudo transversal de prevalência de IST, realizado em cinco capitais brasileiras (Campo Grande, Manaus, Porto Alegre, Salvador e São Paulo) entre dezembro de 2019 e julho de 2021. As 1.317 mulheres trans e travestis, com idade ≥18 anos, recrutadas por meio do método respondent-driven sampling passaram por entrevistas e responderam a um questionário estruturado. Foi ofertada consulta médica, incluindo realização de exame físico e coleta de amostras de vários locais para detectar diversas IST. Para a análise dos fatores associados à aceitabilidade do exame físico (geral, genital e anorretal), considerou-se as características sociodemográficas das participantes que permitiram a sua realização. Resultados: A maioria (65,4%; intervalo de confiança – IC95% 62,7–68,0) concedeu permissão para o exame geral (incluindo orofaríngeo), com permissão concedida em menor proporção para os exames genitais (42,3%; IC95% 39,6–46,0) ou anorretais (42,1%; IC95% 39,4–44,9). No geral, 34,4% (IC95% 31,8–37,0) delas recusaram todos os exames. As participantes com sintomas de IST foram significativamente mais propensas a conceder permissão para o exame completo do que as participantes assintomáticas (64,3 vs 37,4%, odds ratio ajustado – AOR=3,6, IC95% 2,4–5,5).

ABSTRACT Objective This study aimed to determine the acceptability and factors associated with uptake of a physical examination for the detection of symptomatic sexually transmitted infections (STIs) by transgender women and travestis in Brazil. Methods: TransOdara was a multi-centric, cross-sectional STI prevalence study conducted among transgender women and travestis in five capital cities (Campo Grande, Manaus, Porto Alegre, Salvador and São Paulo) representing all Brazilian regions, between December 2019 and July 2021. A total of 1,317 self-identified transgender women and travestis aged ≥18 years were recruited using respondent-driven sampling and responded to a standard questionnaire. A medical consultation was offered including a physical examination and collection of samples from multiple sites to detect various STIs. Factors associated with uptake were investigated by reviewing demographic characteristics of participants who gave permission for physical examination (general, genital, and anorectal). Results: Most participants (65.4%, 95% confidence interval — 95%CI 62.7–68.0) gave permission for a general examination (including oropharyngeal), with fewer permitting genital (42.3%, 95%CI 39.6–46.0) or anorectal (42.1%, 95%CI 39.4–44.9) examinations. Overall, 34.4% (95%CI 31.8–37.0) of participants refused all examinations. Participants with STI symptoms were significantly more likely to give permission for full examination than asymptomatic participants (64.3 vs. 37.4%, adjusted odds ratio — AOR=3.6, 95%CI 2.4–5.5). Other factors significantly associated with uptake of a full examination in multivariate analysis included age (AOR=1.5 for ≥25 years), religion (AOR=1.7 for Afro-Brazilian, AOR=1.9 for other religions compared to no religion), and education (AOR=2.0 for higher-level). Conclusion: In the context of STI management, this study found limited acceptance of anogenital examinations among transgender women and travestis, with higher acceptance among those with STI symptoms.

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.

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 Objective Determinar a aceitabilidade e os fatores associados à realização do exame físico para detecção de infecções sexualmente transmissíveis (IST) sintomáticas em mulheres trans e travestis no Brasil. Métodos: Foram utilizados dados do “TransOdara”, estudo transversal de prevalência de IST, realizado em cinco capitais brasileiras (Campo Grande, Manaus, Porto Alegre, Salvador e São Paulo) entre dezembro de 2019 e julho de 2021. As 1.317 mulheres trans e travestis, com idade ≥18 anos, recrutadas por meio do método respondent-driven sampling passaram por entrevistas e responderam a um questionário estruturado. Foi ofertada consulta médica, incluindo realização de exame físico e coleta de amostras de vários locais para detectar diversas IST. Para a análise dos fatores associados à aceitabilidade do exame físico (geral, genital e anorretal), considerou-se as características sociodemográficas das participantes que permitiram a sua realização. Resultados: A maioria (65,4%; intervalo de confiança – IC95% 62,7–68,0) concedeu permissão para o exame geral (incluindo orofaríngeo), com permissão concedida em menor proporção para os exames genitais (42,3%; IC95% 39,6–46,0) ou anorretais (42,1%; IC95% 39,4–44,9). No geral, 34,4% (IC95% 31,8–37,0) delas recusaram todos os exames. As participantes com sintomas de IST foram significativamente mais propensas a conceder permissão para o exame completo do que as participantes assintomáticas (64,3 vs 37,4%, odds ratio ajustado – AOR=3,6, IC95% 2,4–5,5). Os fatores significativamente associados à aceitabilidade do exame completo na análise multivariada incluíram idade (AOR=1,5 para ≥25 anos), religião (AOR=2,0 para afro-brasileiras, AOR=1,9 para outras religiões em comparação com nenhuma religião) e nível de escolaridade (AOR=2,0 para nível superior). Conclusão: No contexto do manejo de IST, nós observamos aceitação limitada de exames anogenitais entre mulheres trans e travestis, com maior aceitação entre aquelas com sintomas de IST.

ABSTRACT This study conducted among transgender women in São Paulo, Brazil assessed the acceptability and suitability of screening sexually transmitted infections (STIs), such as Chlamydia trachomatis and Neisseria gonorrhoeae, by sampling multiple anatomical sites (i.e. urethral, anorectal, oropharyngeal, and neovaginal), and utilizing self- or provider-collection methods. First, a convenience sample of 23 cohort participants were recruited during a scheduled study visit between October and November 2018. Data collection was through a short investigator-led quantitative survey in Portuguese, and included presentation of investigator-designed, gender-neutral instructional diagrams to guide self-sampling. Three supplemental focus group discussions (FGDs) with a total of 30 participants guided by semi-structured script were conducted in Portuguese between September and October 2019. All participants reported being assigned male sex at birth and self-identified with a feminine gender identity at time of study. All survey respondents (100%; n = 23) indicated willingness to provide samples for STI screening during a future study visit. Preference was for self-collection of urine samples (83%; n = 19), urethral swabs (82%; n = 18), and anorectal swabs (77%; n = 17). A lower preference for self-collection of oropharyngeal swabs (48%; n = 11) was observed. Most respondents (78%; n = 18) indicated that they would not prefer specimens to be collected by a health professional, mainly due to ‘more privacy’ (72%; n = 13). All respondents indicated that they would feel comfortable to provide a self-collected sample based on instructional diagrams shown. In FGDs, although the collection by a health professional was described as a technically safer option for some participants, there was a preference for self-collection to avoid discomfort and embarrassment in exposing the body. Overall, this sub-study suggested acceptability among transgender women of introducing self-sampling for etiological diagnosis of STIs from potential infection sites. Uptake and usability will be explored further in a cross-sectional STI prevalence study of transgender women in Brazil.
