Prevalência de Violência Sexual com contato e sem contato contra homens brasileiros e fatores associados a sexo forçado / Prevalence of contact and non-contact sexual violence against Brazilian men and factors associated with forced sex

RESUMO Objetivou-se estimar a prevalência da Violência Sexual (VS) contra homens brasileiros e fatores associados. Estudo transversal, que estimou a prevalência de várias formas de VS entre homens brasileiros por meio de questionário virtual. Participaram do estudo 1.241 homens de todos os estados. A maioria era jovem, entre 18 e 39 anos de idade (61,7%), heterossexual (50,2%), do Sudeste (54,4%), das classes socioeconômicas C/D/E (72,1%) e brancos (64,3%). Sobre as prevalências de VS, 70,5% afirmaram ter sofrido VS sem contato, 43,1%, VS com contato, 23,9%, VS com penetração, e 33,1%, sexo forçado. Ser bissexual, ser homossexual e ser divorciado/separado aumentaram as chances de sofrer sexo forçado. Este estudo indica que homens bissexuais e homossexuais têm mais chances de sofrer VS, corroborando outras pesquisas. Entre divorciados/separados, as chances de sofrer VS também se mostraram significativas e precisam ser mais bem exploradas. O estudo oferece a possibilidade de problematização para acolhimento de homens vítimas de VS, pensando majoritariamente na prevenção de efeitos adversos após a violência e na implantação de políticas públicas da área da saúde mais direcionadas para o público-alvo, considerando os principais fatores associados.

ABSTRACT We aimed to estimate the prevalence of sexual violence against Brazilian men and associated factors. A cross-sectional study was conducted, which estimated the prevalence of various forms of sexual violence among Brazilian men by means of a virtual questionnaire. A total of 1241 men from all Brazilian states participated in the study. Most participants were young men between 18 and 39 years (61.7%), heterosexual (50.2%), from the Southeast (54.4%), from socioeconomic classes C/D/E (72.1%), and white (64.3%). Regarding the prevalences of sexual violence, 70.5% reported non-contact sexual violence, 43.1% sexual violence with contact, 23.9% sexual violence with penetration, and 33.1% forced sex. Being bisexual homosexual, and being divorced/separated increased the odds of experiencing forced sex. This study indicates that bisexual and homosexual men are more likely to suffer sexual violence, corroborating other research. Among divorced/separated men the chances of experiencing sexual violence were also significant and need to be further explored. The study offers the possibility of problematization for the care of male victims of sexual violence, focusing mainly on the prevention of adverse effects after violence and the implementation of public policies in health that are more directed to the target audience, considering the main associated factors.

Sexual violence against men in Brazil: underreporting, prevalence, and associated factors / Violência sexual contra homens no Brasil: subnotificação, prevalência e fatores associados

ABSTRACT OBJECTIVES Identifying and mapping the literature regarding sexual violence against Brazilian boys and men, as well as describing its underreporting, prevalence, and associated factors. METHODS We conducted a scoping review by searching PubMed, Biblioteca Digital Brasileira de Teses e Dissertações, Biblioteca Virtual em Saúde, Scopus, and Web of Science databases. The inclusion criteria were: (a) surveys including data on sexual violence; (b) inclusion of boys or men as victims of sexual violence; (c) presenting statistical data on prevalence, underreporting, and factors associated with sexual violence among Brazilian boys and men. RESULTS We found a total of 1,481 papers. Ultimately, 53 were included and had their data extracted. Most studies are quantitative in nature (n = 48). The total number of participants across studies was 1,416,480 and the prevalence of sexual violence ranged from 0.1% to 71%. It is important to note that underreporting statistical data was cited in several studies. The group with the highest prevalences was men who have sex with men and those with sexual dysfunctions. Increased tendency to drug use, social isolation, unprotected anal sex, suicidal ideation, sexual dysfunction, and post-traumatic stress disorder were statistically significant predictors for having experienced sexual violence. CONCLUSIONS Despite the prevalence of sexual violence being high against Brazilian boys and men, this area of is surprisingly understudied and there are few studies with this exclusive scope. Social cultural issues, such as sexism, contribute to the underreporting of sexual violence. Additionally, we identified issues related to mental, sexual and reproductive health to be associated with sexual violence. Based on our findings, we recommend the implementation and development of a structural infrastructure aimed at supporting boys and men who are victims of sexual violence, and preventing negative outcomes for this affected group.

RESUMO OBJETIVOS Identificar e mapear a literatura referente à violência sexual contra meninos e homens brasileiros, bem como descrever sua subnotificação, sua prevalência e os fatores associados. MÉTODOS Realizou-se uma revisão de escopo com buscas nas bases de dados: PubMed, Biblioteca Digital Brasileira de Teses e Dissertações, Biblioteca Virtual em Saúde, Scopus e Web of Science. Os critérios de inclusão foram: (a) pesquisas que incluíssem dados sobre violência sexual; (b) inclusão de meninos ou homens como vítimas de violência sexual; (c) apresentassem dados sobre prevalência, subnotificação e fatores associados à violência sexual entre meninos e homens brasileiros. RESULTADOS Foram encontrados 1.481 trabalhos. No total, 53 foram incluídos e tiveram seus dados extraídos. A maioria dos estudos é de natureza quantitativa (n = 48). O total de participantes em todos os estudos foi de 1.416.480 e a prevalência de violência sexual variou de 0.1% a 71%. A subnotificação foi um aspecto citado em vários estudos. Entre os grupos com maiores prevalências estão os homens que fazem sexo com homens e com disfunções sexuais. Maior tendência ao uso de drogas, isolamento social, sexo anal desprotegido, ideação suicida, disfunções sexuais e transtorno de estresse pós-traumático foram alguns dos fatores associados. CONCLUSÕES A violência sexual contra meninos e homens brasileiros é pouco estudada e existem poucos estudos com esse recorte exclusivo, apesar da prevalência de a violência sexual ser alta. Questões culturais, como o machismo, contribuem para a subnotificação da violência sexual. Em relação aos fatores associados, identificamos questões relacionadas à saúde mental, sexual e reprodutiva. Recomenda-se que seja estruturado acolhimento para meninos e homens vítimas de violência sexual, prevenindo ou minimizando desfechos negativos.

Young age and sex work are associated with HIV seroconversion among transgender women in São Paulo, Brazil

Background: Transgender women worldwide have among the highest prevalence of HIV and the lowest access to prevention among groups at risk. However, few longitudinal studies have directly measured HIV incidence and identified predictors of HIV acquisition among transgender women. Setting: São Paulo, Latin America's largest city. Methods: We conducted a longitudinal study among transgender women in São Paulo. Participants were recruited by a long-chain peer referral process from May 2017 to July 2019. Those age 18 years and older and HIV-negative at baseline were retested every 6 months up to 18 months. HIV incidence was calculated by dividing the number of seroconversions by the person-years (py) of follow-up; 95% confidence intervals (CI) were constructed assuming a Poisson distribution. Conditional maximum likelihood ratios assessed differences in HIV incidence by risk factors. Results: A racial/ethnically diverse sample of 545 transgender women were enrolled. In 485.5 py of follow-up, 13 seroconversions were observed yielding an incidence of 2.68 per 100 py (95% CI 1.43­4.58). HIV incidence was significantly higher among transgender women age 18 to 24 years (rate ratio 3.85, 95% CI 1.24­12.93) and among those who engaged in sex work in the preceding month (rate ratio 5.90, 95% CI 1.71­26.62). Conclusion: HIV transmission continues at a high rate among transgender women in Brazil. Factors such as young age, lower level of education, and limited employment opportunities may lead to dependence upon sex work which in turn increase HIV risk. Transgender-friendly prevention services, particularly programs delivering pre-exposure prophylaxis (PrEP) are urgently needed.

Incidental irradiation of internal mammary lymph nodes in breast cancer: conventional two-dimensional radiotherapy versus conformal three-dimensional radiotherapy / Irradiação incidental da cadeia mamária interna no câncer de mama: comparação entre a técnica convencional (bidimensional) e a técnica tridimensional

Abstract Objective: To evaluate incidental irradiation of the internal mammary lymph nodes (IMLNs) through opposed tangential fields with conventional two-dimensional (2D) or three-dimensional (3D) radiotherapy techniques and to compare the results between the two techniques. Materials and Methods: This was a retrospective study of 80 breast cancer patients in whom radiotherapy of the IMLNs was not indicated: 40 underwent 2D radiotherapy with computed tomography for dosimetric control, and 40 underwent 3D radiotherapy. The total prescribed dose was 50.0 Gy or 50.4 Gy (2.0 or 1.8 Gy/day, respectively). We reviewed all plans and defined the IMLNs following the Radiation Therapy Oncology Group recommendations. For the IMLNs, we analyzed the proportion of the volume that received 45 Gy, the proportion of the volume that received 25 Gy, the dose to 95% of the volume, the dose to 50% of the volume, the mean dose, the minimum dose (Dmin), and the maximum dose (Dmax). Results: Left-sided treatments predominated in the 3D cohort. There were no differences between the 2D and 3D cohorts regarding tumor stage, type of surgery (mastectomy, breast-conserving surgery, or mastectomy with immediate reconstruction), or mean delineated IMLN volume (6.8 vs. 5.9 mL; p = 0.411). Except for the Dmin, all dosimetric parameters presented higher mean values in the 3D cohort (p < 0.05). The median Dmax in the 3D cohort was 50.34 Gy. However, the mean dose to the IMLNs was 7.93 Gy in the 2D cohort, compared with 20.64 Gy in the 3D cohort. Conclusion: Neither technique delivered enough doses to the IMLNs to achieve subclinical disease control. However, all of the dosimetric parameters were significantly higher for the 3D technique.

Resumo Objetivo: Avaliar a irradiação incidental dos linfonodos da cadeia mamária interna (LCMIs) com campos tangenciais opostos por meio de radioterapia bidimensional (2D) convencional ou tridimensional (3D) e comparar as duas técnicas quanto aos resultados obtidos. Materiais e Métodos: Trata-se de um estudo retrospectivo com 80 pacientes com câncer de mama sem indicação de radioterapia dos LCMIs: 40 foram submetidos a radioterapia 2D com tomografia computadorizada para controle dosimétrico e 40 foram submetidos a radioterapia 3D. A dose total prescrita foi 50,0 Gy ou 50,4 Gy (2,0 ou 1,8 Gy/dia, respectivamente). Os planos de tratamento foram analisados e os LCMIs foram definidos conforme as recomendações do Radiation Therapy Oncology Group. No tocante aos LCMIs, foram analisadas a proporção do volume que recebeu 45 Gy, a proporção do volume que recebeu 25 Gy, a dose para 95% do volume, a dose para 50% do volume, a dose média, a dose mínima (Dmín) e a dose máxima (Dmáx). Resultados: Tratamentos do lado esquerdo predominaram na coorte 3D. Não houve diferenças entre as coortes 2D e 3D quanto ao estágio do tumor, ao tipo de cirurgia (mastectomia, cirurgia conservadora ou mastectomia com reconstrução imediata) ou à média do volume delineado dos LCMIs (6,8 vs. 5,9 mL; p = 0,411). À exceção da Dmín, todos os parâmetros dosimétricos apresentaram médias maiores na coorte 3D (p < 0,05). A mediana da Dmáx na coorte 3D foi 50,34 Gy. No entanto, a dose média nos LCMIs foi 7,93 Gy na coorte 2D e 20,64 Gy na coorte 3D. Conclusão: Nenhuma das duas técnicas emitiu doses suficientes aos LCMIs para que se alcançasse o controle subclínico da doença. No entanto, todos os parâmetros dosimétricos foram significativamente maiores com a técnica 3D.
