Evaluating social protection mitigation effects on HIV/AIDS and Tuberculosis through a mathematical modelling study.

The global economic downturn due to the COVID-19 pandemic, war in Ukraine, and worldwide inflation surge may have a profound impact on poverty-related infectious diseases, especially in low-and middle-income countries (LMICs). In this work, we developed mathematical models for HIV/AIDS and Tuberculosis (TB) in Brazil, one of the largest and most unequal LMICs, incorporating poverty rates and temporal dynamics to evaluate and forecast the impact of the increase in poverty due to the economic crisis, and estimate the mitigation effects of alternative poverty-reduction policies on the incidence and mortality from AIDS and TB up to 2030. Three main intervention scenarios were simulated-an economic crisis followed by the implementation of social protection policies with none, moderate, or strong coverage-evaluating the incidence and mortality from AIDS and TB. Without social protection policies to mitigate the impact of the economic crisis, the burden of HIV/AIDS and TB would be significantly larger over the next decade, being responsible in 2030 for an incidence 13% (95% CI 4-31%) and mortality 21% (95% CI 12-34%) higher for HIV/AIDS, and an incidence 16% (95% CI 10-25%) and mortality 22% (95% CI 15-31%) higher for TB, if compared with a scenario of moderate social protection. These differences would be significantly larger if compared with a scenario of strong social protection, resulting in more than 230,000 cases and 34,000 deaths from AIDS and TB averted over the next decade in Brazil. Using a comprehensive approach, that integrated economic forecasting with mathematical and epidemiological models, we were able to show the importance of implementing robust social protection policies to avert a significant increase in incidence and mortality from AIDS and TB during the current global economic downturn.

Racial HIV Testing Inequalities in Adolescent Men who have Sex with Men and Transgender Women in Three Brazilian Cities.

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.

The effects of social determinants of health on acquired immune deficiency syndrome in a low-income population of Brazil: a retrospective cohort study of 28.3 million individuals.

Background: Social determinants of health (SDH) include factors such as income, education, and race, that could significantly affect the human immunodeficiency virus and acquired immunodeficiency syndrome (HIV/AIDS). Studies on the effects of SDH on HIV/AIDS are limited, and do not yet provide a systematic understanding of how the various SDH act on important indicators of HIV/AIDS progression. We aimed to evaluate the effects of SDH on AIDS morbidity and mortality. Methods: A retrospective cohort of 28.3 million individuals was evaluated over a 9-year period (from 2007 to 2015). Multivariable Poisson regression, with a hierarchical approach, was used to estimate the effects of SDH-at the individual and familial level-on AIDS incidence, mortality, and case-fatality rates. Findings: A total of 28,318,532 individuals, representing the low-income Brazilian population, were assessed, who had a mean age of 36.18 (SD: 16.96) years, 52.69% (14,920,049) were female, 57.52% (15,360,569) were pardos, 34.13% (9,113,222) were white/Asian, 7.77% (2,075,977) were black, and 0.58% (154,146) were indigenous. Specific socioeconomic, household, and geographic factors were significantly associated with AIDS-related outcomes. Less wealth was strongly associated with a higher AIDS incidence (rate ratios-RR: 1.55; 95% confidence interval-CI: 1.43-1.68) and mortality (RR: 1.99; 95% CI: 1.70-2.34). Lower educational attainment was also greatly associated with higher AIDS incidence (RR: 1.46; 95% CI: 1.26-1.68), mortality (RR: 2.76; 95% CI: 1.99-3.82) and case-fatality rates (RR: 2.30; 95% CI: 1.31-4.01). Being black was associated with a higher AIDS incidence (RR: 1.53; 95% CI: 1.45-1.61), mortality (RR: 1.69; 95% CI: 1.57-1.83) and case-fatality rates (RR: 1.16; 95% CI: 1.03-1.32). Overall, also considering the other SDH, individuals experiencing greater levels of socioeconomic deprivation were, by far, more likely to acquire AIDS, and to die from it. Interpretation: In the population studied, SDH related to poverty and social vulnerability are strongly associated with a higher burden of HIV/AIDS, most notably less wealth, illiteracy, and being black. In the absence of relevant social protection policies, the current worldwide increase in poverty and inequalities-due to the consequences of the COVID-19 pandemic, and the effects of war in the Ukraine-could reverse progress made in the fight against HIV/AIDS in low- and middle-income countries (LMIC).

A Transgender Chatbot (Amanda Selfie) to Create Pre-exposure Prophylaxis Demand Among Adolescents in Brazil: Assessment of Acceptability, Functionality, Usability, and Results.

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.

Unwillingness to prescribe PrEP by health care professionals of specialized HIV/AIDS services in Northeastern Brazil / Disposição para oferta de PrEP por profissionais de saúde de serviços especializados em HIV/aids no Nordeste do Brasil / Resistencia de los profesionales de la salud de los servicios especializados en VIH/SIDA a indicar la PrEP en el Nordeste de Brasil

This study aimed to analyze factors associated with the unwillingness to prescribe pre-exposure prophylaxis (PrEP) by health care professionals of specialized HIV/AIDS services. This is a cross-sectional study with 252 health care professionals in 29 specialized care services (SCSs) in HIV/AIDS in 21 municipalities in the state of Bahia, Brazil. The inclusion criterion was that the professional had worked for at least six months in the service. Sociodemographic, occupational, and behavioral data were collected using a questionnaire. Logistic regression was performed with an estimation of crude and adjusted odds ratio (OR) and respective 95% confidence intervals (95%CI). The unwillingness to prescribe PrEP was 15.2% (95%CI: 10.8-19.6). The factors associated with unwillingness to prescribe PrEP were non-prescription of HIV self-tests for key populations (adjustedOR = 5.4; 95%CI: 1.3-22.4) nor post-exposure prophylaxis (adjustedOR = 2.00; 95%CI: 1.3-3.1), location of the SCS in the state capital (adjustedOR = 3.9; 95%CI: 1.4-10.2), and SCSs without PrEP offer (adjustedOR = 1.7; 95%CI: 1.1-2.8); professionals who have not reported the need to conduct training and courses (adjustedOR = 1.3; 95%CI: 1.1-1.8), or training with more experienced professionals (adjustedOR = 1.8; 95%CI: 1.1-3.8), was associated with a lower proportion of unwillingness to prescribe PrEP. Our results indicate that health care professionals' contextual, organizational, and training factors can contribute to PrEP indication. We suggest expanding ongoing training in combined HIV prevention among health care professionals and increasing the availability of PrEP in health services.

O objetivo deste estudo foi analisar fatores associados a não disposição para oferta de profilaxia pré-exposição (PrEP) por profissionais de saúde de serviços especializados em HIV/aids. Este é um estudo transversal, realizado com 252 profissionais de saúde de 29 serviços de atenção especializada (SAEs) em HIV/aids em 21 municípios do Estado da Bahia, Brasil. Para ser incluído no estudo, o profissional precisava estar trabalhando há pelo menos seis meses no serviço. Dados sociodemográficos, ocupacionais e comportamentais foram coletados por meio de questionário. Foi realizada regressão logística, com estimativa de razão de chances (OR) bruta e ajustada, com os respectivos intervalos de 95% de confiança (IC95%). A relutância em prescrever PrEP foi de 15,2% (IC95%: 10,8-19,6). Os fatores associados à relutância em prescrever PrEP foram a não prescrição de autotestes de HIV para populações-chave (ORajustada = 5,4; IC95%: 1,3-22,4) nem profilaxia pós-exposição (ORajustada = 2,00; IC95%: 1,3-3,1), localização do SAE na capital do estado (ORajustada = 3,9; IC95%: 1,4-10,2) e SAE sem oferta de PrEP (ORajustada = 1,7; IC95%: 1,1-2,8); profissionais que não relataram a necessidade de realizar treinamentos e cursos (ORajustada = 1,3; IC95%: 1,1-1,8) ou treinamento com profissionais mais experientes (ORajustada = 1,8; IC95%: 1,1-3,8) foram associados a uma menor proporção de relutância em prescrever PrEP. Nossos resultados indicam que os fatores contextuais, organizacionais e de treinamento dos profissionais de saúde podem contribuir para a indicação da PrEP. Sugerimos expandir o treinamento existente em prevenção combinada ao HIV entre os profissionais de saúde e aumentar a disponibilidade de PrEP nos serviços de saúde.

El objetivo de este estudio fue analizar los factores asociados con la resistencia de los profesionales de la salud de los servicios especializados en VIH/SIDA a prescribir la profilaxis preexposición (PrEP). Se trata de un estudio transversal, realizado con 252 profesionales de la salud de 29 servicios de atención especializada (SAE) en VIH/SIDA en 21 municipios del estado de Bahía, Brasil. Los criterios de inclusión en el estudio fueron tener experiencia laboral de al menos seis meses en el servicio. Los datos sociodemográficos, ocupacionales y conductuales se recogieron mediante cuestionario. Se realizó regresión logística, con estimaciones de odds ratios (OR) cruda y ajustada, con los respectivos intervalos de 95% de confianza (IC95%). La resistencia a prescribir PrEP fue del 15,2% (IC95%: 10,8-19,6). Los factores asociados con la resistencia a prescribir la PrEP fueron no prescribir autopruebas de VIH para poblaciones clave (ORajustada = 5,4; IC95%: 1,3-22,4) ni la profilaxis posexposición (ORajustada = 2,00; IC95%: 1,3-3,1), ubicación del SAE en la capital del estado (ORajustada = 3,9; IC95%: 1,4-10,2) y SAE sin oferta de PrEP (ORajustada = 1,7; IC95%: 1,1-2,8); los profesionales que no reportaron la necesidad de hacer capacitación y cursos (ORajustada = 1,3; IC95%: 1,1-1,8) o capacitación con profesionales con mayor experiencia (ORajustada = 1,8; IC95%: 1,1-3,8) se asociaron con una menor proporción de resistencia a prescribir PrEP. Los resultados indican que los factores contextuales, organizativos y formativos de los profesionales de la salud pueden contribuir a la indicación de la PrEP. Se recomienda que se amplíe la capacitación existente sobre prevención combinada del VIH entre los trabajadores de la salud y aumente la disponibilidad de PrEP en los servicios de salud.

Building bridges to care: the experience of peer navigation in enabling linkage to PrEP for adolescent men who have sex with men and transgender women / Construindo pontes para o cuidado: a experiência da navegação de pares na habilitação do vínculo com a PrEP para homens adolescentes que fazem sexo com homens e mulheres transgêneros / Construcción de puentes hacia el cuidado: la experiencia de navegación entre pares para permitir la vinculación con la PrEP para hombres adolescentes que tienen relaciones sexuales con hombres y mujeres transgénero

Vulnerable populations are at increased risk for HIV/AIDS, especially adolescent men who have sex with men (AMSM) and adolescent travestis and transgender women (ATGW). Pre-exposure prophylaxis (PrEP) is one component of combination HIV prevention and is already available for these populations in Brazil. However, ensuring its uptake entails certain challenges since inequality and barriers have traditionally marked access and linkage to the related public health services. Peer navigation could be a way of mediating the linkage process because it involves peers keeping track of others' care schedules, dynamically fostering linkage to care according to the needs of users and the actors involved in their everyday care contexts. Therefore, this study proposes analyzing peer-navigator-mediated linkage to PrEP care for 15- to 19-year-old MSM and transgender women from the PrEP1519 project in Salvador, Bahia State, Brazil. In total, 15 field notebooks/diaries, written in April-July 2019, by four peer navigators were analyzed, as were the transcripts of one focal group and 20 semi-structured interviews with adolescents (17 MSM and three trans women) between June and December 2019. Linkage via peer navigator and participant is influenced by emotional dynamics and shared personal characteristics. It is fluid and unstable and calls for care practices to be shaped to meet each participant's needs. For peer navigation to be adopted as a care strategy for sexually transmitted infection prevention and treatment, it should envisage not only increased linkage to care but also sensitivity to service users' specific characteristics and lived experiences.

No entanto, garantir a captação da PrEP implica certos desafios, uma vez que o acesso e a vinculação aos serviços públicos de saúde relacionados a ela tem sido tradicionalmente marcados pela desigualdade e por outras barreiras. A navegação de pares pode ser uma forma de mediar o processo de vinculação pois envolve os pares que acompanham as rotinas de cuidado dos outros, estimulando dinamicamente a vinculação ao cuidado de acordo com as necessidades dos usuários e dos atores envolvidos em seus cotidianos. Este estudo propõe, portanto, analisar a vinculação ao cuidado com a PrEP mediada por navegação de pares para homens que fazem sexo com homens e mulheres transgênero de 15 a 19 anos do projeto PrEP1519 em Salvador, Bahia, Brasil. Foram analisados 15 cadernos/diários de campo escritos por 4 navegadores(as) de pares em abril a julho de 2019 assim como as transcrições de um grupo focal e 20 entrevistas semiestruturadas com adolescentes (17 HSH e três mulheres trans) de junho a dezembro de 2019. O vínculo entre navegador e participante é influenciado pela dinâmica emocional e características pessoais compartilhadas. É fluido e instável e necessita que as práticas de cuidado sejam moldadas para atender às necessidades de cada participante. Para que a navegação de pares seja adotada como estratégia de cuidado para prevenir e tratar infecções sexualmente transmissíveis, o método deve prever não apenas o aumento da vinculação ao cuidado mas também a sensibilidade às características específicas dos usuários e as suas experiências de vida.

Las poblaciones vulnerables tienen mayor riesgo de contraer el VIH/SIDA, especialmente los hombres adolescentes que tienen sexo con hombres (AHSH) y las mujeres adolescentes transgénero y travestis. La profilaxis previa a la exposición (PrEP) es un componente de la combinación de prevención del VIH y ahora está disponible para estas poblaciones en Brasil. Sin embargo, la obtención de la PrEP implica ciertos desafíos, ya que el acceso y los vínculos con los servicios de salud pública relacionados con la PrEP han sido marcados en general por la desigualdad y otras barreras. La navegación entre pares puede ser una forma de mediar el proceso de vinculación, puesto que involucra a los pares acompañando las rutinas de cuidado de los demás, estimulando dinámicamente el vínculo del cuidado según las necesidades de los usuarios y actores involucrados en su cotidiano. Este estudio propone analizar el vínculo del cuidado de la PrEP mediada por la navegación entre pares para hombres que tienen relaciones sexuales con hombres y mujeres transgénero, con edades entre los 15 y los 19 años y que participan en el proyecto PrEP1519 en Salvador, Bahia, Brasil. Cuatro navegantes pares analizaron 15 cuadernos/diarios de campo escritos entre abril y julio de 2019, así como las transcripciones de un grupo focal y 20 entrevistas semiestructuradas con adolescentes (17 HSH y tres mujeres trans) realizadas de junio a diciembre de 2019. El vínculo entre el navegador y el participante estuvo influenciado por dinámicas emocionales y características personales compartidas. Este vínculo es fluido e inestable, además requiere que las prácticas de cuidado sean capaces de satisfacer las necesidades de cada participante. Para que la navegación entre pares sea una estrategia de cuidado en la prevención y tratamiento de las infecciones de transmisión sexual, el método necesita proporcionar no solo una mayor vinculación con el cuidado, sino también una concientización de las características específicas de los usuarios y sus experiencias de vida.

Las poblaciones vulnerables tienen mayor riesgo de contraer el VIH/SIDA, especialmente los hombres adolescentes que tienen sexo con hombres (AHSH) y las mujeres adolescentes transgénero y travestis. La profilaxis previa a la exposición (PrEP) es un componente de la combinación de prevención del VIH y ahora está disponible para estas poblaciones en Brasil. Sin embargo, la obtención de la PrEP implica ciertos desafíos, ya que el acceso y los vínculos con los servicios de salud pública relacionados con la PrEP han sido marcados en general por la desigualdad y otras barreras. La navegación entre pares puede ser una forma de mediar el proceso de vinculación, puesto que involucra a los pares acompañando las rutinas de cuidado de los demás, estimulando dinámicamente el vínculo del cuidado según las necesidades de los usuarios y actores involucrados en su cotidiano. Este estudio propone analizar el vínculo del cuidado de la PrEP mediada por la navegación entre pares para hombres que tienen relaciones sexuales con hombres y mujeres transgénero, con edades entre los 15 y los 19 años y que participan en el proyecto PrEP1519 en Salvador, Bahia, Brasil. Cuatro navegantes pares analizaron 15 cuadernos/diarios de campo escritos entre abril y julio de 2019, así como las transcripciones de un grupo focal y 20 entrevistas semiestructuradas con adolescentes (17 HSH y tres mujeres trans) realizadas de junio a diciembre de 2019. El vínculo entre el navegador y el participante estuvo influenciado por dinámicas emocionales y características personales compartidas. Este vínculo es fluido e inestable, además requiere que las prácticas de cuidado sean capaces de satisfacer las necesidades de cada participante. Para que la navegación entre pares sea una estrategia de cuidado en la prevención y tratamiento de las infecciones de transmisión sexual, el método necesita proporcionar no solo una mayor vinculación con el cuidado, sino también una concientización de las características específicas de los usuarios y sus experiencias de vida.

Willingness of health care providers to offer HIV self-testing from specialized HIV care services in the northeast of Brazil.

BACKGROUND: The insufficient knowledge regarding the serological status of people affected with human immunodeficiency virus (HIV) is a concern in Brazil. HIV self-testing (HIVST) has been proved to have great potential for increasing testing, especially among vulnerable populations. The large-scale distribution of HIVST by the Brazilian public health system has increased in recent years. We aimed to investigate the awareness of HIVST among health care providers (HCP) from specialized HIV/AIDS care services in the state of Bahia, Northeast Brazil. Further we investigated HCP acceptability and willingness to offer its use. METHODS: A cross-sectional study on HCP from 29 specialized care services (SCS) located in 21 cities in the state of Bahia. HCP working in the service for at least 6 months were included. Sociodemographic, occupational, and behavioral data were collected using a questionnaire. Descriptive statistics were carried out. Bivariate, and multivariate analyses estimating adjusted odds ratios (aOR) and 95% confidence intervals (95% CI) using logistic regression were conducted. RESULTS: The awareness and acceptability of HIVST and the willingness to provide it were 79.8, 55.2, and 47.1%, respectively. Few HCP reported that the SCS where they worked dispensed HIVST (3.6%), and 13.5% received some information or training on HIVST. Factors associated with willingness to offer HIVST were: HIVST acceptability (aOR = 9.45; 95% CI: 4.53-19.71), willingness to use HIVST on themselves (aOR = 4.45; 95% CI: 1.62-12.24), confidence in offering HIVST to clients (aOR = 5.73; 95% CI: 2.26-12.72), and considering everyone eligible for HIVST (aOR = 2.88; 95% CI: 1.25-6.59). CONCLUSIONS: Although most HCP were aware of HIVST, acceptability and willingness to provide it to the clients was moderate. The scale up of HIVST as a mean for the HIV prevention and control policy in Brazil, requires further training of HCP and better implementation of this program.

Fonte habitual de cuidado em saúde e o uso de serviços de saúde sexual e reprodutiva entre mulheres trabalhadoras do sexo no Brasil / Fuente habitual de cuidados de salud y el uso de los servicios de salud sexual y reproductiva entre mujeres trabajadoras sexuales en Brasil / Usual source of healthcare and use of sexual and reproductive health services by female sex workers in Brazil

Ter uma fonte habitual de cuidado pode melhorar o acesso a serviços de saúde e ações de prevenção. Assim, o objetivo foi estimar a proporção e fatores associados à fonte habitual de cuidado entre mulheres trabalhadoras do sexo. É um inquérito sociocomportamental com 4.328 mulheres trabalhadoras do sexo, ≥ 18 anos, realizado em 12 cidades brasileiras. Essas mulheres foram recrutadas pelo método respondent-driven sampling (RDS). Foi realizada uma análise descritiva do perfil das mulheres trabalhadoras do sexo que possuíam fonte habitual de cuidado e investigada sua associação aos indicadores de acesso à prevenção do HIV e à saúde reprodutiva. Utilizou-se como medidas de efeito o odds ratio (OR) ajustado em um modelo de regressão logística. Os dados foram ponderados pelo estimador RDS-II. Referiram ter fonte habitual de cuidado, 71,5% das mulheres trabalhadoras do sexo e, destas, 54,3% indicaram a atenção primária à saúde (APS) como a principal fonte habitual de cuidado. Entre as mulheres trabalhadoras do sexo com idades de 18-24 anos, observou-se associação entre a fonte habitual de cuidado e a realização de exame de preventivo ginecológico (OR = 2,27; IC95%: 1,66-3,12), realização de sete ou mais consultas de pré-natal (OR = 2,56; IC95%: 1,30-5,03) e utilização de método contraceptivo (OR = 1.64; IC95%: 1.09-2.46). Entre as mulheres trabalhadoras do sexo com idade ≥ 25 anos, verificou-se associação entre a fonte habitual de cuidado e a participação em palestras sobre infecções sexualmente transmissíveis (IST) (OR = 1,45; 1,12-1,89), conhecimento prévio de profilaxia pós-exposição (OR = 1,32; IC95%: 1,02-1,71) e realização de exame de preventivo ginecológico (OR = 1,92; IC95%: 1,54-2,40). Os resultados deste estudo mostraram que as mulheres trabalhadoras do sexo têm a APS como principal fonte habitual de cuidado. Além disso, a fonte habitual de cuidado pode impactar nos cuidados e ações em relação à saúde reprodutiva e à prevenção de HIV e IST nessa população.

Contar con una fuente habitual de cuidado puede mejorar el acceso a servicios de salud, así como las acciones de prevención. El objetivo fue estimar la proporción de fuente habitual de cuidado, y analizar factores asociados entre mujeres trabajadoras del sexo de 12 ciudades brasileñas. Se trata de una encuesta sociocomportamental con 4.328 mujeres trabajadoras del sexo, edad ≥ 18 años en 12 ciudades brasileñas. Las mujeres trabajadoras del sexo se reclutaron mediante el método respondent-driven sampling (RDS). Se realizó un análisis descriptivo del perfil de las mujeres trabajadoras del sexo que poseían fuente habitual de cuidado. Y se analiza la asociación entre fuente habitual de cuidado e indicadores de acceso a la prevención del VIH, así como a la salud reproductiva, a través del odds ratio (OR) ajustado en modelos de regresión logística. Los dados fueron ponderados mediante el estimador RDS-II. Un 71,5% de las mujeres trabajadoras del sexo informaron tener fuente habitual de cuidado, de estas un 54,31% indicaron la atención primaria en salud. Entre las mujeres trabajadoras del sexo con ≥ 25 años se observó una asociación entre fuente habitual de cuidado y participación en ponencias sobre infecciones sexualmente trasmisibles (IST) (OR = 1,45; IC95%: 1,12-1,89), uso de método anticonceptivo (OR = 1.64; IC95%: 1.09-2.46), conocimiento previo de la profilaxia pos-exposición (OR = 1,32; IC95%: 1,02-1,71), haber realizado un examen preventivo ginecológico (OR = 1,92; IC95%: 1,54-2,40) y haber tenido 7 o más consultas prenatales (OR = 2,56; IC95%: 1,30-5,03). Los resultados de este estudio muestran que las trabajadoras sexuales tienen la APS como su principal fuente habitual de atención. Además, la fuente habitual de atención puede impactar la atención y las acciones en relación con la salud reproductiva y la prevención del VIH y las ITS en esta población.

The fact of having a usual source of care can improve access to health services and preventive activities. The article aimed to estimate the proportion of factors associated with usual source of care among female sex workers. This was a socio-behavioral survey with 4,328 female sex workers, ≥ 18 years, in 12 Brazilian cities. Female sex workers were recruited by the respondent-driven sampling method (RDS). A descriptive profile was performed of the female sex workers who had usual source of care and the association was analyzed between usual source of care and indicators of access to HIV prevention and reproductive health. As effect measure, the study used adjusted odds ratio (OR) in a logistic regression model. The data were weighted by the RDS-II estimator. 71.5% of the female sex workers reported having a usual source of care, and of these, 54.3% cited primary healthcare (PHC) as their main usual source of care. Among female sex workers 18-24 years of age, there was an association between usual source of care and having a Pap smear test (OR = 2.27; 95%CI: 1.66-3.12), seven or more prenatal visits (OR = 2.56; 95%CI: 1.30-5.03), and the use of a contraceptive method (OR = 1.64; 95%CI: 1.09-2.46). Among female sex workers ≥ 25 years, there was an association between usual source of care and attending talks on sexually transmitted infections (STIs) (OR = 1.45; 95%CI: 1.12-1.89), prior knowledge of post-exposure prophylaxis (OR = 1.32; 95%CI: 1.02-1.71), and history of Pap smear test (OR = 1.92; 95%CI: 1.54-2.40). The study's results showed that female sex workers have PHC as their main usual source of care. usual source of care can also positively impact care and activities in reproductive health and prevention of HIV and STIs in this population group.

Health equity and COVID-19: global perspectives.

The COVID-19 is disproportionally affecting the poor, minorities and a broad range of vulnerable populations, due to its inequitable spread in areas of dense population and limited mitigation capacity due to high prevalence of chronic conditions or poor access to high quality public health and medical care. Moreover, the collateral effects of the pandemic due to the global economic downturn, and social isolation and movement restriction measures, are unequally affecting those in the lowest power strata of societies. To address the challenges to health equity and describe some of the approaches taken by governments and local organizations, we have compiled 13 country case studies from various regions around the world: China, Brazil, Thailand, Sub Saharan Africa, Nicaragua, Armenia, India, Guatemala, United States of America (USA), Israel, Australia, Colombia, and Belgium. This compilation is by no-means representative or all inclusive, and we encourage researchers to continue advancing global knowledge on COVID-19 health equity related issues, through rigorous research and generation of a strong evidence base of new empirical studies in this field.

Factors associated with exchanging sex for money in men who have sex with men in Brazil. / Fatores associados à troca de sexo por dinheiro em homens que fazem sexo com homens no Brasil.

This study aimed to analyze the association between sociodemographic, programmatic and contextual factors and the receipt of money in exchange for sex among men who have sex with men (MSM). This is a multicenter, cross-sectional study conducted in ten Brazilian cities between 2008 and 2009. Adult MSM recruited through the Respondent Driven Sampling (RDS) were interviewed. Weighted Odds Ratio (ORw) was obtained through logistic regression, retaining the variables associated with the event (p < 0.05) in the final model. Of the total sample, 33.3% reported receiving money in exchange for sex in the last 12 months before the interview. The variables that were independently associated with the event were age less than or equal to 25 years, lower education, lower social classes, previous history of syphilis, using sites or services to find sexual partners in the previous month, very high risk behavior, using illicit drugs in the previous six months, self-identifying as heterosexual or bisexual, having suffered physical violence due to sexual orientation and having suicidal thoughts always or most of the time. It was observed that MSM who received money in exchange for sex had greater socioeconomic, programmatic and contextual vulnerability, potentially increasing the risk of HIV infection than the other MSM in the sample.

Objetivou-se analisar a associação entre fatores sociodemográficos, programáticos e contextuais e ter recebido dinheiro em troca de sexo entre homens que fazem sexo com homens (HSH). Estudo multicêntrico, transversal, realizado em 10 cidades brasileiras, entre 2008 e 2009. Foram entrevistados 3.749 HSH selecionados pela técnica amostral "Respondent Driven-Sampling" (RDS). "Odds Ratio" ponderado (ORp) foi obtido por meio de regressão logística, permanecendo no modelo final as variáveis associadas ao evento (p < 0,05). Da amostra total, 33,3% relataram ter recebido dinheiro em troca de sexo nos últimos 12 meses anteriores à entrevista. As variáveis associadas com o evento foram ter idade ≤ 25 anos, menor nível de escolaridade, classes sociais mais baixas, história prévia de infecção por sífilis, utilizar locais de encontros para ter parceiros sexuais, ter comportamento de risco para HIV muito alto e usar drogas ilícitas, se autoidentificarem como heterossexual ou bissexual, ter sofrido violência física devido à orientação sexual e apresentar ideação suicida sempre ou na maioria das vezes. Observa-se que os HSH que receberam dinheiro em troca de sexo apresentaram maior vulnerabilidade socioeconômica, programática e contextual, potencialmente aumentando o risco de infecção pelo HIV em relação aos demais HSH.

Discrimination based on sexual orientation against MSM in Brazil: a latent class analysis.

INTRODUCTION: Discrimination based on sexual orientation can influence vulnerability to HIV, increasing exposure to risky sexual behavior among men who have sex with men (MSM). OBJECTIVES: To analyze data using latent class analysis (LCA) to identify groups of individuals with specific patterns of discrimination based on sexual orientation (DSO). METHODS: Cross-sectional study using respondent-driven sampling in 12 Brazilian cities in 2016. LCA was used to characterize discrimination among MSM based on 13 variables in the survey questionnaire. The proportions of men reporting DSO and other variables of interest were estimated using Gile's Successive Sampling estimator. RESULTS: Most MSM were young, single, had a religion, had a high school or college degree, black or brown skin color, and socioeconomic status classified as average. More than half of the participants reported that they had been discriminated against during the last 12 months due to their sexual orientation (65%), more than a third said they had felt afraid of walking in public places during the past 12 months, and about one-fifth of participants reported having been victims of physical or sexual assault due to DSO. DSO was classified into four latent classes: "very high", "high", "moderate" and "low", with estimates of 2.2%, 16.4%, 35.1%, and 46.19%, respectively. CONCLUSION: We observed a high proportion of discrimination against MSM in this study. The use of LCA differentiated parsimoniously classes of discrimination.

Sex work stigma and non-disclosure to health care providers: data from a large RDS study among FSW in Brazil.

BACKGROUND: Stigma in health services may be detrimental to health seeking attitudes and practices. This study investigates non-disclosure of sex work to health care providers among female sex workers (FSW) in Brazil and its association with the utilization of health care services. METHODS: This study used cross-sectional respondent-driven sampling, carried out in 12 Brazilian cities to identify HIV risk behaviors among FSW. We first assessed statistical associations of sociodemographic, human right violations, health service access and utilization, and discrimination variables with non-disclosure of FSW status to health care providers as outcome. Secondly, we investigated the association of non-disclosure of FSW status with selected preventive health care outcomes: HIV testing, PAP smear exam, and post-exposure prophylaxis (PEP). Adjusted odds ratio with 95% confidence intervals were calculated by multivariable logistic regressions. RESULTS: Among 4245 recruited FSW, a high percentage received free condoms (82%) but only 24.4% were counseled on STI. Most FSW used non-specialized public healthcare routinely (62.6%), but only 51.5% had a Pap smear exam in the last two years and less than 40% were tested for HIV in the last 12 months. Among FSW who engaged in risky behavior (49.6%), only 8.3% used PEP. Regarding human rights violations, approximately 15% were required to give part of their earnings to owners of workplace establishments, 38% started sex work under 18 years old and 6% were required to periodically present their HIV test results. 21.3% reported having faced discrimination in health services, and 24.3% always disclosed their FSW status. Multivariable logistic models indicated significant associations of non-disclosure on the four healthcare outcomes, with lower odds of using preventive health services among women who did not disclose their sex work status, even after controlling for age, educational level, NGO affiliation, and type of health care routinely used. CONCLUSIONS: Our results indicate that sex work stigmatization within health services may be one of the main barriers to STI control and HIV response among FSW. It is essential to combat stigmatization and discrimination against FSW in health services to guarantee the appropriate uptake of preventive services available in the public health system in Brazil.

RESUMO Introdução: A discriminação por orientação sexual (DPOS) pode influenciar a vulnerabilidade ao HIV aumentando a exposição a comportamentos sexuais de risco entre homens que fazem sexo com homens (HSH). Objetivos: Examinar dados utilizando a análise de classes latentes (ACL) para identificar grupos de indivíduos com padrões específicos de DPOS. Métodos: Estudo transversal com entrevistados recrutados pelo processo amostral respondent driven sampling em 12 cidades brasileiras em 2016. A ACL foi usada para caracterizar o DPOS entre HSH com base em 13 variáveis do bloco de discriminação do questionário da pesquisa. As proporções de DPOS e das variáveis de interesse, bem como seus intervalos de confiança (95%) foram ponderados usando o estimador de Gile. Resultados: A maioria era de jovens, solteiros, com alguma religião, escolaridade média ou superior, cor da pele preta ou parda e com nível socioeconômico médio. Mais da metade referiu ter sido discriminado nos últimos 12 meses por sua orientação sexual (65%), mais de um terço referiu ter tido medo de andar em lugares públicos nos últimos 12 meses e em torno de um quinto dos participantes reportaram ter sofrido agressão física ou sexual na vida. A DPOS foi classificada em 4 classes latentes, "muito alta", "alta", "média" e "baixa", com estimativas de 2,2%, 16,4%, 35,1% e 46,19%, respectivamente. Conclusão: Observou-se alta proporção de discriminação entre os HSH participantes deste estudo. A utilização da ACL discriminou de maneira parcimoniosa as classes de DPOS.

Incentives and barriers to HIV testing among female sex workers in Ceará.

OBJECTIVE: Estimating HIV prevalence and describing the incentives and barriers for HIV testing among female sex workers. METHODS: This cross-sectional study recruited 402 women aged 18 years or older, residing in Fortaleza, state of Ceará, Brazil, who reported having had sexual intercourse in exchange for money in last four months. The sample was recruited using Respondent Driven Sampling, between August and November 2010. RESULTS: The 84.1% of the sample tested and the estimated prevalence of HIV infection was 3.8%. The sample was young (25 to 39 years ), single (80.0%), with one to three children (83.6%), had eight or more years of schooling (65.7%), and belonged to social classes D/E (53.1%). The majority worked in fixed locations (bars, motels, hotels, sauna - 88.9%), and prostitution was their only source of income (54.1%). About 25% of the sample did not know where to test in the public health sector and 51.8% either never tested or hadn't tested for over a year or more. The main reported barriers to testing were the perceptions that there was no risk of becoming infected (24.1%), and, alternatively, fear of discrimination if the test was positive (20.5%). Incentives for testing were the greater availability of testing sites (57.0%) and health facilities with alternative schedules (44.2%). CONCLUSIONS: Prevalence for HIV was similar to that found in other Brazilian cities in different regions of the country, although higher than the general female population. Non-traditional venues not associated with the health system and availability of testing in health units during non-commercial hours are factors that encourage testing. Not considering oneself to be at risk, fear of being discriminated against and not knowing testing locations are barriers.

RESUMO OBJETIVO Estimar a prevalência do HIV e descrever os incentivos e barreiras à realização do teste para o HIV entre mulheres profissionais do sexo. MÉTODOS Este estudo transversal recrutou 402 mulheres de 18 anos ou mais, residentes em Fortaleza, CE, que informaram ter tido relação sexual em troca de dinheiro nos últimos quatro meses. A amostra foi recrutada por meio da técnica Respondent Driven Sampling, entre agosto e novembro de 2010. RESULTADOS A adesão ao teste de HIV foi de 84,1% e a prevalência estimada da infecção pelo HIV foi de 3,8%. A amostra era jovem (25 a 39 anos), solteira (80,0%), com um a três filhos (83,6 %), tinham oito anos ou mais de estudo (65,7%) e pertencia às classes sociais D/E (53,1%). A maioria exercia a profissão em locais fechados (bares, motéis, hotéis, sauna - 88,9%), e a prostituição era a única fonte de renda (54,1%). Cerca de 25% da amostra desconhecia onde o teste de HIV era realizado na rede pública e 51,8% nunca fez o teste ou se testou há um ano ou mais. As principais barreiras ao teste foram acreditar que não corre risco de se infectar (24,1%) e o medo da discriminação caso o teste fosse reagente (20,5%). Os incentivos foram relacionados à maior oferta de locais para o teste (57,0%) e de unidades de saúde com horários alternativos (44,2%). CONCLUSÕES A prevalência foi semelhante à encontrada em outras cidades brasileiras de diferentes regiões do país, apesar de superiores a de mulheres não profissionais do sexo. A disponibilidade do teste em locais não relacionados à saúde e a oferta nas unidades básicas em horário não comercial são fatores que incentivam a realização do teste. Não se considerar sob-risco, medo de ser discriminada e desconhecimento dos locais onde o teste é realizado podem ser uma barreira para a realização do exame.

The effect of the Family Health Strategy on usual source of care in Brazil: data from the 2013 National Health Survey (PNS 2013).

BACKGROUND: A usual source of care (USC) has been conceptualized as having a health provider or place available for patients to consult when sick or in need of medical care. Having a USC is a means to achieve longitudinality of care with Primary Health Care (PHC) providers. Brazil has made enormous progress in PHC and thus provides an important opportunity to investigate USC in a middle-income country context. METHODS: This study uses data from a nationally representative household survey, the 2013 National Health Survey (n = 62,986), to describe the prevalence of having a USC in Brazil and to investigate to what extent the Family Health Strategy (FHS) has contributed to USC prevalence. Analyses include descriptive, bivariate and multivariable Poisson regression. RESULTS: Show very high rates of people reporting any type of USC (74.4 %) and more than one third reporting PHC as their USC. Household enrolment in the FHS was positively associated with having any USC (PR:1.09; 95 % CI: 1.07-1.12) and a stronger association with having PHC as the regular source of care (PR:1.63;95 % CI:1.54-1.73). FHS enrolment was negatively associated with reporting emergency/urgent care facilities as one's USC (PR: 0.67; 95 % CI: 0.59-0.76). The association between the more consolidated FHS with having a USC was strongest in the poorest regions of the country (North, Northeast and Central-West). Having PHC as one's USC showed a positive dose-response relationship with the FHS in all regions, especially in the Central-West. CONCLUSIONS: Our results have important implications for the health care model in Brazil and in other countries, especially those seeking to base their national health systems more strongly on primary health care. The study suggests expanding primary health care can increase the establishment of a USC which can help assure better monitoring of chronic conditions and attention to patient needs.

Barriers along the care cascade of HIV-infected men in a large urban center of Brazil.

Global and national HIV/AIDS policies utilize the care cascade to emphasize the importance of continued engagement in HIV services from diagnosis to viral suppression. Several studies have documented barriers that men experience in accessing services at specific stages of care, but few have analyzed how these barriers operate along the care cascade. Brazil offers a unique setting for analyzing barriers to HIV care because it is a middle-income country with a large HIV epidemic and free, universal access to HIV/AIDS services. Semi-structured interviews were conducted in 2011 with HIV-infected men (n = 25) receiving care at the only HIV/AIDS state reference center in Salvador, Brazil, the third largest city in the country. Interviews were transcribed and coded for analysis. Researchers identified barriers to services along the care cascade: health service-related obstacles (poor-quality care, lengthy wait times, and drug supply problems); psychosocial and emotional challenges (fear of disclosure and difficulty accepting HIV diagnosis); indirect costs (transportation and absenteeism at work or school); low perceived risk of HIV; and toxicity and complexity of antiretroviral drug (ARV) regimens. The stages of the care cascade interrupted by each barrier were also identified. Most barriers affected multiple, and often all, stages of care, while toxicity and complexity of ARV regimens was only present at a single care stage. Efforts to eliminate more prevalent barriers have the potential to improve care continuity at multiple stages. Going forward, assessing the relative impact of barriers along one's entire care trajectory can help tailor improvements in service provision, facilitate achievement of viral suppression, and improve access to life-saving testing, treatment, and care.
