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

Ignoring the presence of dependent censoring in data analysis can lead to biased estimates, for example, not considering the effect of abandonment of the tuberculosis treatment may influence inferences about the cure probability. In order to assess the relationship between cure and abandonment outcomes, we propose a copula Bayesian approach. Therefore, the main objective of this work is to introduce a Bayesian survival regression model, capable of taking into account the dependent censoring in the adjustment. So, this proposed approach is based on Clayton's copula, to provide the relation between survival and dependent censoring times. In addition, the Weibull and the piecewise exponential marginal distributions are considered in order to fit the times. A simulation study is carried out to perform comparisons between different scenarios of dependence, different specifications of prior distributions, and comparisons with the maximum likelihood inference. Finally, we apply the proposed approach to a tuberculosis treatment adherence dataset of an HIV cohort from Alvorada-RS, Brazil. Results show that cure and abandonment outcomes are negatively correlated, that is, as long as the chance of abandoning the treatment increases, the chance of tuberculosis cure decreases.

RESUMO

BACKGROUND: Despite the preventive policies adopted, reduction in sexually transmitted infections (STIs) among men who have sex with men (MSM) has been limited. The risk of hepatitis C virus (HCV) infection has increased among the most vulnerable population groups, including MSM. The aim of this study was to estimate the prevalence of HCV infection and to assess risky practices among MSM from 12 Brazilian cities. METHODS: This study was carried out from June to December 2016 using respondent driven sampling (RDS). Participants completed a self-administered questionnaire to collect behavioral, socioeconomic, and demographic variables. In addition, the rapid diagnostic test (RDT) for HCV was offered. Positive results were sent to Instituto Adolfo Lutz for confirmation. RESULTS: A total of 4,176 participants were recruited and 23 samples were sent for confirmation. Of these, 16 were confirmed, resulting in a prevalence of 0.7% (95% CI: 0.3%-1.7%). The Southeast region showed a prevalence of 0.9% (95% CI: 0.3-2.6), followed by the South region, with 0.6% (95% CI: 0.2-2.1). The Northeast region had a prevalence of 0.3% (95% CI: 0.1-1.0) and the Midwest 0.1% (95% CI: 0.0-0.7). No positive cases were found in the North. Single men aged 40 years or older were the majority of participants exposed to HCV. High levels of alcohol consumption, illicit drug use, irregular condom use, in addition to infection with other STIs, were associated with exposure to HCV. CONCLUSIONS: STIs continue to be important health problems in Brazil and globally. Many STIs are inapparent for many years until they bring more serious consequences. Extra investment in HCV is also warranted, given that it can be eliminated. Relying solely on clinical data to provide information about inapparent infection, especially in stigmatized populations, will make that goal more difficult to achieve. Surveillance studies, such as the one reported here need to be repeated over time to demonstrate trends and to provide information for evaluation, program and policies. Investments in the most vulnerable populations are critical to achieve the World Health Organization global health goals including the elimination of viral hepatitis by 2030.

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

The purpose of this study was to identify factors associated with HIV and vulnerability contexts for women in Porto Alegre, Brazil. The participants were 1326 women recruited by complex sampling design, divided into two groups: 640 women with HIV (WLH) and 686 women who did not have HIV (WNLH). Gross and weighted statistical analyses were performed. Logistic regression models were used to estimate the odds ratio (OR) for 12 variables. The main results demonstrated that WLH had lower income (p < .001) and poorer education (p = .038), and few used condoms during their first sexual intercourse (p < .001). The occurrence of HIV was higher among the black population (p < .001). Sex in exchange for money (p < .001) and sexually transmitted infections (p < .001) were more frequent among WLH than among WNLH. The age of sexual debut and age difference from the partner at first sexual intercourse (FSI) were not associated with the outcome. The high percentage of non-use of condoms during the FSI shows how vulnerable individuals are right at the beginning of their sexual lives. More effective prevention strategies can be developed by nurses in view of the contexts of vulnerability surrounding women.

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

BACKGROUND: Scientific journals play a critical role in research validation and dissemination and are increasingly vocal about the identification of research priorities and the targeting of research results to key audiences. No new journals specialising in health policy and systems research (HPSR) and focusing in the developing world or in a specific developing world region have been established since the early 1980s. This paper compares the growth of publications on HPSR across Latin America and the world and explores the potential, feasibility and challenges of innovative publication strategies. METHODS: A bibliometric analysis was undertaken using HPSR MeSH terms with journals indexed in Medline. A survey was undertaken among 2500 authors publishing on HPSR in Latin America (LA) through an online survey, with a 13.1% response rate. Aggregate indicators were constructed and validated, and two-way ANOVA tests were performed on key variables. RESULTS: HPSR publications on LA observed an average annual growth of 27.5% from the years 2000 to 2018, as against 11.4% worldwide and yet a lag on papers published per capita. A total of 48 journals with an Impact Factor publish HPSR on LA, of which 5 non-specialised journals are published in the region and are ranked in the bottom quintile of Impact Factor. While the majority of HPSR papers worldwide is published in specialised HPSR journals, in LA this is the minority. Very few researchers from LA sit in the Editorial Board of international journals. Researchers highly support strengthening quality HPSR publications through publishing in open access, on-line journals with a focus on the LA region and with peer reviewers specialized on the region. Researchers would support a new open access journal specializing in the LA region and in HPSR, publishing in English. Open access up-front costs and disincentives while waiting for an Impact Factor can be overcome. CONCLUSION: Researchers publishing on HPSR in LA widely support the launching of a new specialised journal for the region with a vigorous editorial policy focusing on regional and country priorities. Strategies should be in place to support English-language publishing and to develop a community of practice around the publication process. In the first years, special issues should be promoted through a priority-setting process to attract prominent authors, develop the audience and attain an Impact Factor.

RESUMO

BACKGROUND: The Community Health Workers (CHWs) Programme was launched in Luanda, Angola, in 2007 as an initiative of the provincial government. The aim of this study was to assess its implementation process. METHODS: This is a case study with documental analysis, CHWs reports data, individual interviews and focus groups. RESULTS: Until June 2009, the programme had placed in the community 2,548 trained CHWs, providing potential coverage for 261,357 families. Analysis of qualitative data suggested an association of CHWs with improvements in maternal and child access to health care, as well as an increase in the demand for health services, generating further need to improve service capacity. Nevertheless, critical points for programme sustainability were identified. CONCLUSIONS: For continuity and scaling up, the programme needs medium- and long-term technical, political and financial support. The results of this study may be useful in strengthening and reformulating the planning of the CHWs programme in Luanda and in Angola. Moreover, the lessons learned with this experience can also provide insight for the development of CHWs programmes in other parts of the world. By means of cooperation, Brazil has supported the implementation of this CHWs programme and can potentially contribute to its improvement.

RESUMO

OBJECTIVE: To identify groups of transgender women and travestis (TGW) with specific patterns of gender-based discrimination (GBD) and analyze the factors associated with GBD. METHODS: A cross-sectional study was conducted with TGW recruited through respondent-driven sampling in five Brazilian cities (2019-2021). Latent class analysis was used to characterize GBD (low, medium, and high) using 14 observable variables. Descriptive analysis was performed, and associations between predictor variables and GBD were estimated by adjusted odds ratios (aOR) using ordinal logistic regression. RESULTS: Out of a total of 1,317 TGW, 906 (68.8%) answered questions about GBD. Most were under 34 years old, single, and had a Brown race/skin color. GBD was classified as "low," "medium," and "high," with estimates of 41.7, 44.5, and 13.8%, respectively. Variables positively associated with higher intensity of GBD included living in Manaus compared to São Paulo, being ≤34 years old compared to >34, being homeless compared to living in one's own house or rented apartment, not having legally changed one's name compared to those who had, and reporting physical or sexual violence compared to those who did not report. Variables negatively associated with higher intensity of GBD included having a Brown or Asian race/skin color compared to White and a monthly income ≥1 minimum wage compared to ³1. CONCLUSION: A high proportion of GBD was observed in Brazilian TGW, with this outcome associated with more vulnerable sociodemographic characteristics and a history of violence.

RESUMO

OBJECTIVE: The objective of the present study is to describe the sociodemographic and behavioral characteristics of a group of transgender women and travestis (TGW) with a history of incarceration and the institutional and social context of this experience in Brazil. METHODS: The analyzed data were derived from the TransOdara Study, a cross-sectional study conducted in five Brazilian capitals from December 2019 to July 2021. Participants were recruited using the Respondent-Driven Sampling (RDS) technique, in which, after an initial formative and exploratory stage, the first participants were identified; in turn, these participants recruited up to six other transgender women and travestis for the research. The study's outcome was the experience of incarceration throughout life, captured through the question: "Have you ever been arrested in your life?" RESULTS: A total of 1,245 TGW were interviewed, of which 20.3% (n=253) experienced incarceration. Incarceration was more frequent among those aged 33 to 42 years (35.6%), with lower level of education (45.5%, p<0.001), engaged in informal work (30.3%), without a partner (67.2%), and among those who reported illicit drug use (66.4%). The majority (60.9%) of TGW were incarcerated with cisgender men, and the most common reasons for imprisonment were drug trafficking (30.4%) followed by robbery (29.2%). Over a quarter of the interviewees (26.3%) experienced assault, and 13.8% reported experiencing sexual violence during incarceration. CONCLUSION: The results emphasize the high prevalence of incarceration among TGW. This incarceration takes place in male wards and in a context of high rates of physical and sexual violence.

RESUMO

OBJECTIVE: To describe the prevalence, characteristics, and factors associated with sexual violence in transgender women and travestis (TGW) in Brazil. METHODS: This cross-sectional study was conducted in five Brazilian cities (Campo Grande, Manaus, Porto Alegre, Salvador, and São Paulo) between 2019 and 2021. Participants were recruited using the respondent-driven sampling (RDS) technique. The outcome of interest is the self-reported experience of sexual violence throughout the respondents' lifetime. We evaluated the actions taken by victims of sexual violence and how they dealt with the experience. Logistic regression analysis was employed to examine the associations between sociodemographic and behavioral factors (such as race, income, drug use, sex work, and access to healthcare) and the outcome. RESULTS: A total of 1,317 TGW were interviewed. Among them, 53% (n=698) reported experiencing sexual violence. For 64.4% (n=419) of the respondents, sexual violence occurred on more than one occasion. The majority of TGW did not seek health services (93.2%, n=648), disclose the violence (93.9%, n=653), nor seek support from family or friends (86.5%, n=601). A higher prevalence of sexual violence was associated with homelessness (adjusted prevalence ratio - aPR=1.69, 95% confidence interval - 95%CI 1.01-2.84), a history of engaging in sex work (aPR=2.04, 95%CI 1.46-2.85), self-reporting regular, bad, or very bad emotional health (aPR=1.67, 95%CI 1.28-2.19), and experiencing difficulties accessing health services in the previous year (aPR=2.78, 95%CI 1.74-4.43). CONCLUSION: The high prevalence of sexual violence, analyzed together with the actions of the victims, indicates a context of high vulnerability and low institutional support. In this scenario, violence can be exacerbated, resulting in severe health consequences.

RESUMO

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

Our objective was to compare HIV prevalence between two national surveys among men who have sex with men in Brazil in 2009 and 2016. HIV prevalence was estimated stratifying by age and socioeconomic status. HIV prevalence increased from 11.9% [95% confidence interval (CI): 9.9-14.3], in 2009, to 19.1% (95% CI: 16.5 - 22.0), in 2016 [odds ratio (OR) = 1.8; 95% CI: 1.3-2.3] increasing 320% among Young MSM of low SES. Political leadership is needed to develop a scientifically sound and inclusive solution.

RESUMO

OBJECTIVE: To estimate the prevalence and factors associated with hepatitis A, B, and C in transgender women and travestis's networks, in 5 regions of Brazil. METHODS: This cross-sectional study includedtransgender women and travestis in five Brazilian capitals (Campo Grande, Manaus, Porto Alegre, Salvador, and São Paulo), between December/2019 and July/2021. All samples were subjected to detection of serological markers of hepatitis virus A (HAV), B (HBV), and C (HCV) infections through rapid tests and chemiluminescent microparticle immunoassays. Positive samples in the screening tests were submitted to detect HBV DNA and HCV-RNA by real-time PCR and genotyped by Sanger sequencing. RESULTS: Analysis of 1,317 samples showed network prevalence rates of 69.1%, 25.1%, and 1.5% for HAV, HBV, and HCV exposure, respectively. A high susceptibility rate to HBV infection (35.7%) and low prevalence of vaccine response markers (40%) were also observed. Age greater than 26 years, self-declared black/brown skin color, having only primary education, history of incarceration, and use of a condom in the last sexual intercourse with a casual partner were associated with total anti-HAV. Exposure to HBV was associated with age greater than 26 years, self-declared black/brown, history of being a sex worker, and incarceration. Age > 37 years, history of sexual abuse, and frequent alcohol consumption were associated with hepatitis C infection. CONCLUSION: The highest prevalence of HAV in this population was found in the North and Northeast regions, and the prevalence found was higher than that in the general population, suggesting greater vulnerability. The prevalence of HCV infection in our study was similar to that observed in the general population.

RESUMO

OBJECTIVE: To analyze how clinical and social events may impact adherence to antiretroviral treatment for HIV. METHODS: This is a historical cohort study with 528 patients who underwent treatment for HIV in a specialized care service in Alvorada, RS. A total of 3429 queries executed between the years 2004 and 2017 were analyzed. For each visit, data on treatment characteristics and the patients' clinical picture were collected. Adherence, as measured by patients' self-report, was the endpoint of the study. The logistic regression model via generalized estimating equations was used for estimating the associations. RESULTS: 67.8% of the patients analyzed have up to 8 years of education and 24.8% have a history of crack and/or cocaine use. Among men, being asymptomatic [odds ratio (OR) = 1.43; 95%CI 1.05-1.93], having more than 8 years of education (OR= 2.32; 95%CI 1.27-4.23), and never having used crack (RC = 2.35; 95%CI 1.20-4.57) were associated with adherence. For women, being older than 24 years (CR = 1.82; 95%CI 1.09-3.02), never having used cocaine (CR = 2.54; 95%CI 1.32-4.88) and being pregnant (RC = 3.28; 95%CI 1.83-5.89) increased the odds of adherence. CONCLUSIONS: In addition to defined sociodemographic characteristics, one-off events that may occur in the trajectory of patients on long treatment, such as starting a new pregnancy and not having symptoms, can impact patients' chances of treatment adherence.

RESUMO

OBJETIVE: Studies have shown that the practice of self-medicating children occurs worldwide and is independent of the country's economic level, medication policies, or access to health services. This study aimed to estimate and characterize the prevalence of self-medication in the Brazilian population of children aged up to 12 years. METHODS: We analyzed the data of 7528 children aged up to 12 years whose primary caregivers responded to the National Survey on Access, Use and Promotion of Rational Use of Medicines in Brazil (PNAUM), a cross-sectional population-based study conducted in 245 Brazilian municipalities. The prevalence of self-medication was defined as the use of at least one medication without a doctor's or dentist's indication 15 days before the interview. RESULTS: The prevalence of self-medication was 22.2% and was more frequent in older children belonging to poorer families and without health insurance. The acute conditions for which there was a higher frequency of self-medication were pain, fever, and cold/allergic rhinitis. Analgesics/antipyretics stood out among the most used medications for self-medication. CONCLUSIONS: The prevalence of self-medication to treat acute conditions was high in Brazilian children sampled in PNAUM, emphasizing the management of common symptoms such as pain, fever, and cold/allergic rhinitis in this age group. These findings reinforce the need for educational actions aimed at parents and caregivers.

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

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.
