RESUMO

BACKGROUND: The effective testing of sexually transmitted infections (STIs) requires sampling from potential infection sites. This study aimed to assess the choice, satisfaction, and performance of self-collected samples (SCS) from potential infection sites for STI testing among transgender women in Brazil. METHODS: TransOdara was a multicentric, cross-sectional STI prevalence study conducted in 5 Brazilian cities. Using respondent-driven sampling, 1317 transgender women 18 years or older were recruited. Participants completed interviewer-led questionnaires and provided swab samples from multiple sites (anorectal, oropharyngeal, genital) for Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and human papillomavirus (HPV) testing. Participants were given a choice of SCS or provider-collected samples (PCS) at each site. RESULTS: Most participants selected SCS for anorectal (74.9%; 95% confidence interval [CI], 72.4-77.3) and genital (72.7%; 95% CI, 70.2-75.1) sites, whereas fewer chose for oropharyngeal samples (49.8%; 95% CI, 47.0-52.6). For future testing, most participants expressed a preference for SCS for genital (72.2%; 95% CI, 69.5-74.7) and anorectal (70.2%; 95% CI, 67.6-72.7) sites. There was no significant difference in the positive test results for CT and NG between SCS and PCS at anorectal and oropharyngeal sites, or for HPV at anorectal and genital (penile or neovaginal) sites. CONCLUSIONS: This study demonstrated a high level of acceptability and usability of self-sampling for STI testing among transgender women. A preference for SCS was evident at the anorectal and genital sites, and the results of SCS were comparable to those of PCS. The findings suggest that multisite STI testing utilizing self-collection methods as a provided option can be effectively integrated into sexual health services for transgender women.

RESUMO

The HIV epidemic affects men who have sex with men (MSM) disproportionally in Brazil, and pre-exposure prophylaxis (PrEP) is effective for preventing HIV in this population. However, low perceived risk of HIV may influence the acceptability and decision to use PrEP. This study estimated the association between self-perception of HIV risk and acceptability of daily oral PrEP among Brazilian MSM. Respondent-driven sampling (RDS) was used for behavioral and biological surveillance to recruit 4,176 MSM 18 years or over in 12 Brazilian cities in 2016. Results were weighted using Gile's estimator in RDS Analyst software. Adjusted odds rations (OR) with 95% confidence intervals were calculated using multivariate logistic regression. Acceptability of daily oral PrEP was high (69.7%) among the 3,544 MSM available for analysis. Most participants self-reported low or moderate risk of HIV infection (67.2%) and a small proportion (9.3%) reported high risk. A dose-response relationship was observed between acceptability of PrEP and self-reported risk: PrEP acceptability was 1.88 times higher (OR 1.8; 95% CI: 1.24-2.85) among MSM whose perceived risk of HIV infection was low or moderate, and 5 times higher (OR 5.68; 95% CI: 2.54-12.73) among those who self-reported high risk compared to MSM reporting no HIV risk. MSM with the highest risk perception of HIV reported higher rates of PrEP acceptability. Given the availability of daily oral PrEP in the public health care system in Brazil, we suggest emphasizing counseling about self-perception of HIV risk as part of routine HIV prevention services.

RESUMO

BACKGROUND: There are many inequalities in terms of prevention and treatment for pregnant women with HIV and exposed children in low and middle-income countries. The Brazilian protocol for prenatal care includes rapid diagnostic testing for HIV, compulsory notification, and monitoring by the epidemiological surveillance of children exposed to HIV until 18 months after delivery. The case is closed after HIV serology results are obtained. Lost to follow-up is defined as a child who was not located at the end of the case, and, therefore, did not have a laboratory diagnosis. Lost to follow-up is a current problem and has been documented in other countries. This study analyzed factors associated with loss to follow-up among HIV-exposed children, including sociodemographic, behavioral, and health variables of mothers of children lost to follow-up. METHODS: This historical cohort study included information on mothers of children exposed to HIV, born in Porto Alegre, from 2000 to 2017. The research outcome was the classification at the end of the child's follow-up (lost to follow-up or not). Factors associated with loss to follow-up were investigated using the Poisson regression model. Relative Risk calculations were performed. The significance level of 5% was adopted for variables in the adjusted model. RESULTS: Of 6,836 children exposed to HIV, 1,763 (25.8%) were classified as lost to follow-up. The factors associated were: maternal age of up to 22 years (aRR 1.25, 95% CI: 1.09-1.43), the mother's self-declared race/color being black or mixed (aRR 1.13, 95% CI: 1.03-1.25), up to three years of schooling (aRR 1.45, 95% CI: 1.26-1.67), between four and seven years of schooling (aRR 1.14, 95% CI: 1.02-1.28), intravenous drug use (aRR 1.29, 95% CI: 1.12-1.50), and HIV diagnosis during prenatal care or at delivery (aRR 1.37, 95% CI: 1.24-1.52). CONCLUSION: Variables related to individual vulnerability, such as race, age, schooling, and variables related to social and programmatic vulnerability, remain central to reducing loss to follow-up among HIV-exposed children.

RESUMO

BACKGROUND: Brazil has many people living with HIV (PLWH) who are unaware of their serostatus. The public health system has recently added HIV self-testing (HIVST) for key populations such as men who have sex with men (MSM). This study estimates HIVST acceptability among Brazilian MSM and explores factors associated with acceptability among MSM who have never tested for HIV or who had a previous negative result. METHODS: Respondent-driven sampling (RDS) was used to recruit 4176 MSM in 12 Brazilian cities in 2016 to this biological and behavioral surveillance study. We excluded from this analysis all MSM who were aware of their positive HIV serostatus. Descriptive, bivariate and multivariate analyses were conducted. Overall proportions were weighted with Gile's estimator in RDS Analyst software and 95% confidence intervals were calculated. The analyses of HIVST acceptability were stratified by prior HIV testing (never or one or more times). RESULTS: For this analysis, 3605 MSM were included. The acceptability of HIVST was 49.1%, lower among those who had never tested for HIV (42.7%) compared to those who had a previous HIV negative test (50.1%). In the subgroup of MSM who had never tested for HIV, those who reported discrimination or who had a medical appointment in the last 12 months reported higher HIVST acceptability. Among MSM who had a previous negative HIV test, only those reporting condomless receptive anal sex reported higher HIVST acceptability. In addition, we observed that high levels of knowledge of HIV/AIDS, taking part in lesbian, gay, bisexual, and transgender nongovernmental organizations (LGBT-NGO), or complete secondary or incomplete higher undergraduate education reported higher acceptability. CONCLUSIONS: The acceptability of HIVST was low among MSM, especially among those who never tested for HIV. Given access to HIVST in Brazil, we point to the need for programs that enhance promotion of testing addressed to MSM.

RESUMO

Violence in the community can impact access to health care. This scoping review examines the impact of urban violence upon youth (aged 15-24) access to sexual and reproductive health and trauma care in Low and Middle Income Countries (LMICs). We searched key electronic health and other databases for primary peer-reviewed studies from 2010 through June 2020. Thirty five of 6712 studies extracted met criteria for inclusion. They were diverse in terms of study objective and design but clear themes emerged. First, youth experience the environment and interpersonal relationships to be violent which impacts their access to health care. Second, sexual assault care is often inadequate, and stigma and abuse are sometimes reported in treatment settings. Third is the low rate of health seeking among youth living in a violent environment. Fourth is the paucity of literature focusing on interventions to address these issues. The scoping review suggests urban violence is a structural and systemic issue that, particularly in low-income areas in LMICs, contributes to framing the conditions for accessing health care. There is a gap in evidence about interventions that will support youth to access good quality health care in complex scenarios where violence is endemic.

RESUMO

OBJECTIVE: This study aimed to evaluate factors associated with inconsistent condom use with casual partners in a population of men who have sex with men (MSM) in Brazil. METHODS: In 2016, 4,176 MSM >18 years were enrolled in 12 capitals of Brazil using a Respondent Driven Sampling (RDS) method. For the construction of the outcome, we evaluated questions about condom use in all anal intercourse (receptive and insertive) in the previous six months and the last sexual intercourse. Estimates were calculated using a weighted complex sample design. We performed a logistic regression analysis to determine the associations between sociodemographic and behavioral factors and inconsistent condom use in sexual relationships with casual male partners. RESULTS: More than half of our sample (50.8%) had not used condoms consistently with casual partners in the previous six months. Inconsistent condom use was significantly associated with: low education (weighted odds ratio - wOR: 1.55; 95% confidence interval - CI 0.99-2.40), lack of counseling on sexually transmitted infections STI (wOR: 1.51; 95%CI 1.05-2.17), non-use of condoms at sexual debut (wOR: 3.05; 95%CI 2.12-4.40) and moderate and high perceived risk for HIV (wOR: 1.51; 95%CI 1.07-2.14). Higher age was negatively associated with inconsistent condom use (wOR=0.97, 95%CI 0.89-0.99). CONCLUSION: Despite being an individual behavior, condom use is related to factors beyond the individual scope. HIV/Aids prevention policies should focus on younger MSM, providing qualified information about condom use, preferably before the beginning of their sexual life.

RESUMO

We aimed to analyze the factors associated with inconsistent condom use among men who have sex with men (MSM) and their commercial sexual partners in Brazil. This is a cross-sectional study with adult MSM who were recruited via respondent-driven sampling (RDS) in 12 Brazilian capitals in 2016. MSM answered a sociobehavioral questionnaire which included questions on their sexual behavior. The inconsistent use of condoms with their clientele was measured via insertive and receptive anal sex in the six months prior to our research and in their last sexual intercourse. The association between independent variables and the inconsistent use of condoms was measured via a Poisson regression model with robust variance and estimation of adjusted prevalence ratios (aPR). Data from 461 MSM were analyzed. We found a 26% prevalence of inconsistent condom use with their clientele (95%CI: 19.0-34.3, n = 123). Belonging to the lowest economic classes (D/E), having medium or low knowledge about HIV, having practiced insertive and receptive anal sex, and having never tested for HIV throughout their lives were associated with inconsistent use of condoms with their clientele. The variables associated with inconsistent use indicated that commercial sex is practiced in a context of greater vulnerability to HIV infection, referring to the need for biomedical and behavioral interventions which focus on access to and use of prevention strategies together with public policies to reduce socioeconomic inequalities among MSM who practice commercial sexual.


O objetivo foi analisar os fatores associados ao uso inconsistente de preservativo com parceiros comerciais entre homens que fazem sexo com homens (HSH) no Brasil. Foi feito um estudo transversal, com HSH adultos, recrutados por meio da técnica respondent-driven sampling (RDS), em 12 capitais brasileiras, em 2016. Os HSH responderam a um questionário sociocomportamental, que incluía questões sobre o comportamento sexual. O uso inconsistente de preservativo com parceiros comerciais foi mensurado por meio das relações sexuais anais insertivas e receptivas, ocorridas nos últimos seis meses e na última relação sexual. A associação entre as variáveis independentes e o uso inconsistente de preservativo foi mensurada utilizando o modelo de regressão de Poisson com variância robusta, com estimação de razões de prevalência ajustadas (RPa). Foram analisados dados de 461 HSH. A prevalência de uso inconsistente de preservativo com parceiros comerciais foi de 26% (IC95%: 19,0-34,3, n = 123). Pertencer às classes econômicas mais baixas (D/E), ter médio ou baixo conhecimento sobre HIV, ter praticado sexo anal insertivo e receptivo e nunca ter realizado teste para HIV na vida são fatores que estiveram associados ao uso inconsistente de preservativo com parceiros comerciais. As variáveis associadas ao uso inconsistente indicaram que o sexo comercial está sendo praticado em um contexto de maior vulnerabilidade à infecção pelo HIV. Nesse sentido, são necessárias intervenções biomédicas e comportamentais, com foco no acesso e na utilização de estratégias de prevenção, aliadas a políticas públicas para a redução de desigualdades socioeconômicas entre HSH que praticam sexo comercial.

RESUMO

INTRODUCTION: Pre-exposure prophylaxis (PrEP) delivery based on user needs can enhance PrEP access and impact. We examined whether telehealth for daily oral PrEP delivery could change the indicators of care related to prophylactic use in five Brazilian public HIV clinics (testing centres, outpatient clinics and infectious disease hospitals). METHODS: Between July 2019 and December 2020, clients on PrEP for at least 6 months could transition to telehealth or stay with in-person follow-up. Clients were clinically monitored until June 2021. A desktop or mobile application was developed, comprising three asynchronous consultations and one annual in-person consultation visit. Predictors influencing telehealth preference and care outcomes were examined. The analysis encompassed intent-to-treat (first choice) and adjustments for sexual practices, schooling, age, duration of PrEP use and PrEP status during the choice period. RESULTS: Of 470 users, 52% chose telehealth, with the adjusted odds ratio (aOR) increasing over time for PrEP use (aOR for 25-months of use: 4.90; 95% CI: 1.32-18.25), having discontinued PrEP at the time of the choice (aOR: 2.91; 95% CI: 1.40-6.06) and having health insurance (aOR: 1.91; 95% CI: 1.24-2.94) and decreasing for those who reported higher-risk behaviour (aOR for unprotected anal sex: 0.51; 95% CI: 0.29-0.88). After an average follow-up period of 1.6 years (95% CI: 1.5-1.7), the risk of discontinuing PrEP (not having the medication for more than 90 days) was 34% lower with telehealth (adjusted hazard ratio: 0.66; 95% CI: 0.45-0.97). When adjusted by mixed linear regression, no differences in adherence (measured by mean medication possession rate) were found between in-person and telehealth (p = 0.486) or at pre- and post-telehealth follow-ups (p = 0.245). Sexually transmitted infections increased between the pre-follow-up and post-follow-up choices and were not associated with in-person or telehealth (p = 0.528). No HIV infections were observed. CONCLUSIONS: Our findings indicate that telehealth for PrEP delivery can enhance service rationalization and reinforce the prevention cascade. This approach reduces prophylaxis interruptions and is mainly preferred by individuals with lower demands for healthcare services.

RESUMO

Hepatitis B virus (HBV) is a global public health problem and requires specific prevention actions, particularly focusing on the key populations, such as men who have sex with men (MSM). We aimed at assessing the prevalence of HBV infection, among MSM, in a multicity study in Brazil. In 2016, we conducted a survey using a respondent-driven sampling methodology in 12 Brazilian cities. Rapid tests (RT) were performed on 3178 samples from those MSM. Positive results were tested for HBV DNA and sequenced. If negative for HBV DNA, samples were tested for serological markers. The prevalence rate of HBV exposure and clearance was 10.1% (95% CI: 8.1-12.6), and 1.1% (95%; CI: 0.6-2.1) were confirmed to be HBsAg-positive. Of those samples tested for anti-HBs (n = 1033), only 74.4% presented a serological profile analogous to that elicited by hepatitis B vaccination. Among HBsAg-positive samples (n = 29), 72.4% were HBV DNA-positive, and from these, 18 were sequenced. HBV genotypes A, F, and G were found in 55.5%, 38.9%, and 5.6%, respectively. This study indicates high prevalence rates of MSM HBV exposure and a low positivity index for the serological marker of HBV vaccine immunity. These findings may contribute to the discussion of strategies to prevent hepatitis B and reinforce the importance of promoting HBV vaccination in this key population.

RESUMO

Discrimination due to sexual orientation (DDSO) has an important association with health outcomes among men who have sex with men (MSM). This study aimed to analyze factors associated with DDSO among MSM in 12 Brazilian cities. This is a cross-sectional study with 4,176 MSM participants recruited in 2016 which used a respondent-driven sampling method in 12 Brazilian cities. DDSO levels were previously identified by a latent class analysis based on 13 variables from the discrimination section. An ordinal logistic regression was used to assess associations with these DDSO levels, and weighted ordinal odds ratios (OR) and their respective 95% confidence intervals (95%CI) were estimated using Gile's estimator. Most participants were young (< 25 years old) black or of mixed-race (pardo), single individuals who had a religious affiliation, primary or incomplete secondary education, and a high and average socioeconomic status. More than half (65%) reported DDSO in the 12 months prior to this study. We observed an independent association among the four latent DDSO classes and the following variables: age < 25 years old (OR = 1.66; 95%CI: 1.21-2.27), white skin color (OR = 1.43; 95%CI: 1.02-2.01), history of sexual (OR = 2.33; 95%CI: 1.58-3.43) and physical violence (OR = 3.08; 95%CI: 2.11-4.49), disclosure of their sexual orientation as MSM to their fathers (OR = 2.00; 95%CI: 1.47-2.72), experienced suicidal ideation in the two weeks prior to this study (OR = 2.09; 95%CI: 1.46-2.98), and use of any illicit drugs in the last six months (OR = 1.61; 95%CI: 1.19-2.18). Our results indicate that contextual factors may contribute to high DDSO levels among MSM in Brazil. Public health policies toward human rights surveillance and protection among MSM must be urgently addressed.

RESUMO

Most studies of sexual violence are with women, and although men who have sex with men (MSM) is the group of the men that has been most investigated for sexual violence, there are still several questions to be answered about sexual violence and sexual revictimization among MSM. This study aimed to estimate the prevalence of sexual violence in different stages of life and identify factors associated with sexual violence in adulthood among Brazilian MSM. We conducted an analysis with data from the study conducted in 2016 with 4,176 MSM from 12 Brazilian cities recruited through respondent-driven sampling (RDS), who answered a survey to a set of questions, among which some specific about sexual violence. Most participants were under 25 years old (56.5%), with more than 12 years of schooling (71.2%), mixed race (40.8%), single (86.2%), and belonging to some religion (50.9%). The lifetime prevalence of sexual violence was 20.3%. In our analyses, having experienced sexual violence in childhood and adolescence increased the odds of experiencing sexual violence in adulthood (prevalence ratio ratios [PRR] 4.93 (95% CI [1.99, 12.21]), as did experiencing physical violence (PRR 1.99; 95% CI [1.07, 3.71]) and receiving money for sex (PRR 2.26; 95% CI [1.17, 4.36]). In addition to violence in childhood and adolescence being risk factors for sexual violence in adulthood, we also observed that half of the sample experienced sexual violence repeatedly, characterizing sexual revictimization. It is important that health services are prepared to receive boys and men victims in order to reduce the chances of revictimization and other outcomes.

RESUMO

BACKGROUND: Tuberculosis is a curable disease, which remains the leading cause of death among infectious diseases worldwide, and it is the leading cause of death in people living with HIV. The purpose is to examine survival and predictors of death in Tuberculosis/HIV coinfection cases from 2009 to 2013. METHODS: We estimated the survival of 2,417 TB/HIV coinfection cases in Porto Alegre, from diagnosis up to 85 months of follow-up. We estimated hazard ratios and survival curves. RESULTS: The adjusted risk ratio (aRR) for death, by age, hospitalization, and Directly Observed Treatment was 4.58 for new cases (95% CI: 1.14-18.4), 4.51 for recurrence (95% CI: 1.11-18.4) and 4.53 for return after abandonment (95% CI: 1.12-18.4). The average survival time was 72.56 ± 1.57 months for those who underwent Directly Observed Treatment and 62.61 ± 0.77 for those who did not. CONCLUSIONS: Case classification, age, and hospitalization are predictors of death. The occurrence of Directly Observed Treatment was a protective factor that increased the probability of survival. Policies aimed at reducing the mortality of patients with TB/HIV coinfection are needed.

RESUMO

Men are the main group affected by HIV infection in Brazil, with an upward trend in the last 10 years. According to official data, heterosexual men represent 49% of cases, followed by homosexuals with 38% and bisexuals with 9.1%. Heterosexual men have been subsumed in the category "overall population" and have failed to receive specific attention in preventive policies or activities. The article proposes to analyze the circumstances and strategies by which heterosexual men learn of their HIV diagnosis. The study thus seeks to understand the paths and social actors involved in their HIV/AIDS diagnosis. The data are from a qualitative study interviewing 36 men living with HIV/AIDS that did not self-identify as homosexuals and/or bisexuals. The men were contacted in three specialized AIDS services in Porto Alegre, Rio Grande do Sul State, Brazil. The results indicate that men consider themselves immune to HIV, and that the diagnosis is an unexpected event. Women (affective-sexual partners and/or former partners) are fundamental components in the men's diagnosis, since they reveal the presence of HIV through either prenatal care or their own illness. An important share of these men discover that they are HIV-positive through some illness such as tuberculosis or after several visits to health services. Spontaneous search for HIV testing only occurs through situations and signs associated with possible infection. Heterosexual men have few opportunities for HIV diagnosis, and beyond gender issues, they are subject to programmatic vulnerability.


Os homens são o principal grupo afetado pela infecção do HIV no Brasil, com tendência de crescimento nos últimos dez anos. Nos dados oficiais, os homens heterossexuais representam 49% dos casos, os homossexuais 38% e os bissexuais 9,1%. Os homens heterossexuais ficaram subsumidos na categoria de "população geral", não recebendo destaque em políticas ou ações de prevenção. O presente artigo se propõe a analisar as circunstâncias e estratégias por meio das quais os homens heterossexuais descobrem o diagnóstico do HIV. Busca-se, assim, compreender os caminhos percorridos, bem como os atores sociais envolvidos no diagnóstico de HIV/aids. Os dados analisados resultam de uma pesquisa qualitativa na qual foram entrevistados 36 homens vivendo com HIV/aids que não se identificam como homossexuais e/ou bissexuais. Esses homens foram contatados em três serviços especializados em aids de Porto Alegre, Rio Grande do Sul, Brasil. Os resultados indicam que eles se consideram imunes ao HIV, sendo o diagnóstico um evento inesperado. As mulheres (parceiras afetivo-sexuais e/ou ex-parceiras) são peças fundamentais para o diagnóstico masculino, pois revelam, seja pelo pré-natal, seja pelo adoecimento, a presença do HIV. Uma parcela importante dos homens se descobre soropositivo por ocasião de alguma doença, como a tuberculose, ou após várias idas e vindas dos serviços de saúde. A busca pela testagem de forma espontânea só acontece mediante a identificação de situações e sinais associados a uma possível contaminação. Os homens heterossexuais possuem poucas oportunidades de diagnóstico do HIV e, para além do gênero, são sujeitos à vulnerabilidade programática.


Los hombres son el principal grupo afectado por la infección del VIH en Brasil, con una tendencia de crecimiento en los últimos 10 años. En los datos oficiales, los hombres heterosexuales representan un 49% de los casos, los homosexuales un 38% y los bisexuales un 9,1%. Los hombres heterosexuales quedaron encajados en la categoría de "población general", no siendo relevantes en políticas o acciones de prevención. Este artículo se propone analizar las circunstancias y estrategias a través de las cuales los hombres heterosexuales descubren el diagnóstico del VIH. Se busca, de esta forma, comprender los caminos recorridos, así como los actores sociales implicados en el diagnóstico del VIH/SIDA. Los datos analizados son resultado de una investigación cualitativa en la que se entrevistaron a 36 hombres, viviendo con VIH/SIDA, que no se identifican como homosexuales y/o bisexuales. Se contactó con estos hombres a través de tres servicios especializados en sida de Porto Alegre, Rio Grande do Sul, Brasil. Los resultados indican que los hombres se consideran inmunes al VIH, siendo el diagnóstico un evento inesperado. Las mujeres (parejas afectivo-sexuales y/o ex-parejas) son piezas fundamentales para el diagnóstico masculino, puesto que revelan, sea a través del cuidado prenatal, sea a través de la enfermedad, la presencia del VIH. Una parte importante de los hombres se descubre seropositiva, debido a alguna enfermedad, como la tuberculosis, o tras varias idas y venidas a los servicios de salud. La búsqueda de un test espontáneo solamente se produce mediante la identificación de situaciones y señales asociadas a una posible infección. Los hombres heterosexuales poseen pocas oportunidades de diagnóstico del VIH y, más allá del género, están sujetos a vulnerabilidad programática.

RESUMO

This paper investigates factors associated with motherhood among adolescents from 14 to 16 years of age in Porto Alegre, Brazil. This is a case-control study with 431 adolescent mothers (cases) and 862 adolescents who had never given birth (controls). D. ata were obtained through home visits by an interviewer-applied questionnaire. Sociodemographic characteristics, quality of social and family relationships, lifestyle and history of abuse were studied as potential determinants to early adolescent motherhood. Conditional logistic regression was used for data analysis according to a two-stage hierarchical model. Results showed that lower economic class, schooling failure, tobacco consumption, alcoholic drunkenness at least once in life and having a mother who gave birth before 20 years of age were positively associated with early adolescent motherhood. Later menarche and having relatives or having friends in whom to trust remained as protective factors. Schooling failure, which obtained the highest risk, points to the important role of the school in this population's development and its potential to stimulate healthy life habits.

RESUMO

INTRODUCTION: High level of HIV/AIDS knowledge is required for an effective adoption of preventive strategies. OBJECTIVE: To assess HIV/AIDS knowledge among men who have sex with men (MSM) in 12 Brazilian cities. METHODS: Respondent-Driven Sampling method was used for recruitment. HIV/AIDS knowledge was assessed by Item Response Theory. Difficulty and discrimination parameters were estimated, and the knowledge score was categorized in three levels: high, medium, and low. Logistic regression was used for analysis. RESULTS: Among 4,176 MSM, the proportion of high level of knowledge was 23.7%. The following variables were positively associated with high knowledge (p < 0.05): age 25+ years old, 12+ years of schooling, white skin color, having health insurance, having suffered discrimination due to sexual orientation, having had a syphilis test, and having received educational material in the previous 12 months. Exchanging sex for money was negatively associated. CONCLUSIONS: The proportion of only 23.7% of high HIV/AIDS knowledge was low. We should note that the only potential source of knowledge acquisition associated with high level of knowledge was receiving educational materials. Our study indicates the need for expansion of public prevention policies focused on MSM and with more effective communication strategies, including the development of knowledge that involves motivation and abilities for a safer behavior.

RESUMO

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.

RESUMO

INTRODUCTION: This paper details the methods used in the second national Biological and Behavioral Surveillance Survey (BBSS) of HIV, syphilis, and hepatitis B and C among men who have sex with men in Brazil. METHODS: Respondent-driven sampling (RDS) was used in 12 cities in 2016. The targeted sample size was initiated with five to six seeds in each city. HIV, syphilis, and Hepatitis B and C rapid tests were offered to participants. RDS Analyst with Gile's successive sampling (SS) estimator was used to adjust results as recommended and a weight for each individual was generated for further analysis. Data for the 12 cities were merged and analyzed using Stata 14.0 complex survey data tools with each city treated as its own stratum. RESULTS: Duration of data collection varied from 5.9 to 17.6 weeks. 4,176 men were recruited in the 12 cities. Two sites failed to achieve targeted sample size due to a six-month delay in local IRB approval. No city failed to reach convergence in our major outcome variable (HIV). CONCLUSION: The comprehensive BBSS was completed as planned and on budget. The description of methods here is more detailed than usual, due to new diagnostic tools and requirements of the new STROBE-RDS guidelines.

RESUMO

ABSTRACT Objective: This study aimed to evaluate factors associated with inconsistent condom use with casual partners in a population of men who have sex with men (MSM) in Brazil. Methods: In 2016, 4,176 MSM >18 years were enrolled in 12 capitals of Brazil using a Respondent Driven Sampling (RDS) method. For the construction of the outcome, we evaluated questions about condom use in all anal intercourse (receptive and insertive) in the previous six months and the last sexual intercourse. Estimates were calculated using a weighted complex sample design. We performed a logistic regression analysis to determine the associations between sociodemographic and behavioral factors and inconsistent condom use in sexual relationships with casual male partners. Results: More than half of our sample (50.8%) had not used condoms consistently with casual partners in the previous six months. Inconsistent condom use was significantly associated with: low education (weighted odds ratio — wOR: 1.55; 95% confidence interval — CI 0.99-2.40), lack of counseling on sexually transmitted infections STI (wOR: 1.51; 95%CI 1.05-2.17), non-use of condoms at sexual debut (wOR: 3.05; 95%CI 2.12-4.40) and moderate and high perceived risk for HIV (wOR: 1.51; 95%CI 1.07-2.14). Higher age was negatively associated with inconsistent condom use (wOR=0.97, 95%CI 0.89-0.99). Conclusion: Despite being an individual behavior, condom use is related to factors beyond the individual scope. HIV/Aids prevention policies should focus on younger MSM, providing qualified information about condom use, preferably before the beginning of their sexual life.


RESUMO Objetivo: Este estudo tem como objetivo avaliar os fatores associados ao uso inconsistente do preservativo com parceiros casuais em uma população de homens que fazem sexo com homens (HSH) no Brasil. Métodos: Trata-se de um estudo transversal, com método de amostragem Respondent Driven Sampling (RDS), desenvolvido em 12 capitais do Brasil, com 4.176 HSH. Para a construção do desfecho, foram avaliadas questões sobre o uso do preservativo em todas as relações anais (receptivas e insertivas) nos últimos seis meses e a última relação sexual. As estimativas foram calculadas usando um desenho amostral complexo ponderado. Realizamos uma análise de regressão logística para determinar as associações entre fatores sociodemográficos e comportamentais e o uso inconsistente do preservativo. Resultados: Mais da metade da nossa amostra (50,8%) não usou preservativo de forma consistente com parceiros casuais nos últimos seis meses. O uso inconsistente do preservativo foi significativamente associado a: falta de aconselhamento sobre infecções sexualmente transmissíveis (weighted odds ratio — wOR: 1,51; intervalo de confiança — IC95% 1,05-2,17), não uso de preservativo na primeira relação sexual (wOR: 3,05; IC95% 2,12-4,40) e autopercepção de risco para o HIV como moderado e alto (wOR: 1,51; IC95% 1,07-2,14). Maior idade foi negativamente associada ao uso inconsistente do preservativo (wOR=0,97, IC95% 0,89-0,99). Conclusão: Apesar de ser um comportamento individual, o uso do preservativo está relacionado a fatores além do âmbito privado. As políticas de prevenção ao HIV/AIDS devem focar nos HSH mais jovens, fornecendo informações qualificadas sobre o uso do preservativo, preferencialmente antes do início da vida sexual.

RESUMO

INTRODUCTION: Periodic monitoring of sociobehavior characteristics at a national level is an essential component of understanding the dynamics the human immunodeficiency virus (HIV) epidemic worldwide, including Brazil. METHODS: This paper compares descriptive sociobehavior characteristics in 2 national cross-sectional HIV biological behavioral surveillance surveys (BBSS) conducted in 2009 and 2016 among men who have sex with men (MSM) in Brazil. Respondent driven sampling (RDS) was used for recruitment in both years. Overall proportions were weighted according to Gile's estimator using RDS Analyst Software and 95% confidence intervals were calculated for comparisons between the 2 periods. Further comparisons were stratified by age groups (<25 and 25+ years old). RESULTS: Overall, 3749 and 4176 MSM were recruited in 2009 and 2016, respectively. In 2016, participants were younger than 25 years old (58.3%), with 12 or more years of education (70.4%), with higher socioeconomic status (40.7%), and had a higher proportion of whites (31.8%), as compared to 2009. Also, participants in 2016 reported less alcohol use and binge drinking, but used illicit drugs more frequently. There was an increase among MSM who self-reported their HIV risk as low and had low HIV knowledge while the proportion of those who were never tested for HIV dropped from 49.8% in 2009 to 33.8% in 2016. Although more than three-quarters received free condoms in both years, STD counseling remained low (32% and 38% for 2009 and 2016, respectively). Sexual risk behavior remained at high levels, especially unprotected anal receptive sex and sex with multiple partners. Younger MSM (<25 years old) showed riskier sexual practices than those 25+ years old, when comparing 2016 to 2009. CONCLUSIONS: Our results indicate a worrisome risk behavior trend among Brazilian MSM, especially among younger ones. These results can contribute for a better understanding of the HIV epidemics in Brazil, with timely shift in strategies so improved effectiveness in public health prevention efforts can be achieved.

RESUMO

This paper reports human immuno-deficiency virus (HIV) prevalence in the 2nd National Biological and Behavioral Surveillance Survey (BBSS) among men who have sex with men (MSM) in 12 cities in Brazil using respondent-driven sampling (RDS).Following formative research, RDS was applied in 12 cities in the 5 macroregions of Brazil between June and December 2016 to recruit MSM for BBSS. The target sample size was 350 per city. Five to 6 seeds were initially selected to initiate recruitment and coupons and interviews were managed online. On-site rapid testing was used for HIV screening, and confirmed by a 2nd test. Participants were weighted using Gile estimator. Data from all 12 cities were merged and analyzed with Stata 14.0 complex survey data analysis tools in which each city was treated as its own strata. Missing data for those who did not test were imputed HIV+ if they reported testing positive before and were taking antiretroviral therapy.A total of 4176 men were recruited in the 12 cities. The average time to completion was 10.2 weeks. The longest chain length varied from 8 to 21 waves. The sample size was achieved in all but 2 cities.A total of 3958 of the 4176 respondents agreed to test for HIV (90.2%). For results without imputation, 17.5% (95%CI: 14.7-20.7) of our sample was HIV positive. With imputation, 18.4% (95%CI: 15.4-21.7) were seropositive.HIV prevalence increased beyond expectations from the results of the 2009 survey (12.1%; 95%CI: 10.0-14.5) to 18.4%; CI95%: 15.4 to 21.7 in 2016. This increase accompanies Brazil's focus on the treatment to prevention strategy, and a decrease in support for community-based organizations and community prevention programs.
