Hepatitis C virus prevalence among men who have sex with men: a cross-sectional study in 12 Brazilian cities.

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.

Analysis of work-related accidents and ill-health in Brazil since the introduction of the accident prevention factor.

BACKGROUND: Since 2004, Brazil has had a national policy for occupational health and safety. This policy means companies' tax burden is altered according to the numbers of work-related accidents and ill-health amongst their workers. In 2010, a multiplication factor was introduced to this policy, called the Accident Prevention Factor. The idea of this new multiplication factor is to encourage individual employers to take initiatives to prevent accidents and ill health in the workplace. This study was designed to investigate the incidence of work-related accidents and ill-health in Brazil according to their causes, their severity, and the economic activity in which they occur, and to compare the data before and after the introduction of the Accident Prevention Factor. METHODS: An ecological study was conducted by analyzing the time series of work-related accidents/ill-health between 2008 and 2014 from the Brazilian social security system (Previdência Social) statistical yearbooks. Incidences were calculated per cause, economic activity, and severity of the accident/ill-health. Data from before and after the introduction of the Accident Prevention Factor were compared using the Mann-Whitney test per cause and per economic activity. Statistical analyses were made using the SPSS software, with significance set at 5%. RESULTS: A reduction in the incidence of work-related accidents/ill-health was found across all the groups of causes analyzed, except for the groups "external causes of morbidity and mortality" and "factors influencing health status and contact with health services." Greater reductions were found for diseases of the musculoskeletal system and connective tissue and diseases of the nervous system. Reductions in work-related accidents/ill-health were found in the different economic activities and in the different severity groups. The highest reduction after the introduction of the Accident Prevention Factor was in manufacturing and production (p < 0.05). CONCLUSIONS: Overall, the incidence of accidents/ill-health was found to be on decline, except those with external causes of morbidity and mortality and those involving factors influencing health status and contact with health services. The biggest reduction was found in manufacturing and production. However, generally speaking progress still needs to be made in accident prevention and occupational health across a whole range of work environments.

Association between firearms and mortality in Brazil, 1990 to 2017: a global burden of disease Brazil study.

BACKGROUND: Brazil leads the world in number of firearm deaths and ranks sixth by country in rate of firearm deaths per 100,000 people. This study aims to analyze trends in and burden of mortality by firearms, according to age and sex, for Brazil, and the association between these deaths and indicators of possession and carrying of weapons using data from the global burden of diseases, injuries, and risk factors study (GBD) 2017. METHODS: We used GBD 2017 estimates of mortality due to physical violence and self-harm from firearms for Brazil to analyze the association between deaths by firearms and explanatory variables. RESULTS: Deaths from firearms increased in Brazil from 25,819 in 1990 to 48,493 in 2017. Firearm mortality rates were higher among men and in the 20-24 age group; the rate was 20 times higher than for women in the same age group. Homicide rates increased during the study period, while mortality rates for suicides and accidental deaths decreased. The group of Brazilian federation units with the highest firearm collection rate (median = 7.5) showed reductions in the rate of total violent deaths by firearms. In contrast, the group with the lowest firearm collection rate (median = 2.0) showed an increase in firearm deaths from 2000 to 2017. An increase in the rate of voluntary return of firearms was associated with a reduction in mortality rates of unintentional firearm deaths (r = -0.364, p < 0.001). An increase in socio-demographic index (SDI) was associated with a reduction in all firearm death rates (r = -0.266, p = 0.008). An increase in the composite index of firearms seized or collected was associated with a reduction in rates of deaths by firearm in the subgroup of females, children, and the elderly (r = -0.269, p = 0.005). CONCLUSIONS: There was a change in the trend of firearms deaths after the beginning of the collection of weapons in 2004. Federation units that collected more guns have reduced rates of violent firearm deaths.

[Not Available]. / Sífilis em parturientes no Brasil: prevalência e fatores associados, 2010 a 2011.

OBJECTIVE: To estimate the prevalence and investigate the factors associated with syphilis in parturient women in Brazil. METHOD: This nationwide cross-sectional population-based study, with regional representativeness, was carried out with parturient women aged 15 to 49 years delivering babies in public healthcare system/partner maternity facilities between January 2010 and December 2011. Syphilis screening was based on a rapid treponemal test. Diagnostic confirmation was based on the Venereal Disease Research Laboratory (VDRL) test and additional treponemal tests. A structured questionnaire was used for collection of clinical and sociodemographic variables. Information regarding pre-natal consultations was obtained from the prenatal card and medical records. The association between the variables of interest and syphilis was investigated using odds ratios and logistic regression. RESULTS: Information was obtained from 36 713 women. The overall prevalence of syphilis for the country was 0.89%; the prevalence in the North, Northeast, Southeast, South, and Mid-West regions was 1.05%, 1.14%, 0.73%, 0.48%, and 1.20% respectively. Seropositive results were associated with absence of prenatal consultations, fewer prenatal consultations, and late start of prenatal consultations. Of the women diagnosed during prenatal consultations, 53.1% were still infected at delivery. Increased risk of syphilis was observed in women of yellow, black, and brown race/skin color as well as in those with fewer years of schooling than in women of white race/skin color and more years of schooling. CONCLUSIONS: A reduction in the prevalence of syphilis in Brazil was recorded. However, this disease is still associated with social and regional inequality.

Improving the quality of external cause of death data in Brazil: evaluation and validation of a new form to investigate garbage codes.

Garbage codes, such as external causes with no specific information, indicate poor quality cause of death data. Investigation of garbage codes via an effective instrument is necessary to convert them into useful data for public health. This study analyzed the performance and suitability of the new investigation of deaths from external causes (IDEC) form to improve the quality of external cause of death data in Brazil. The performance of the IDEC form on 133 external garbage codes deaths was compared with a stratified matched sample of 992 (16%) investigated deaths that used the standard garbage codes form. Consistency between these two groups was checked. The percentage of garbage codes from external causes reclassified into valid causes with a 95% confidence interval (95%CI) was analyzed. Reclassification for specific causes has been described. Qualitative data on the feasibility of the form were recorded by field investigators. Investigation using the new form reduced all external garbage codes by -92.5% (95%CI: -97.0; -88.0), whereas the existing form decreased garbage codes by -60.5% (95%CI: -63.5; -57.4). The IDEC form presented higher effectivity for external-cause garbage codes of determined intent. Deaths that remained garbage codes mainly lacked information about the circumstances of poisoning and/or vehicle accidents. Despite the fact that field investigators considered the IDEC form feasible, they suggested modifications for further improvement. The new form was more effective than the current standard form in improving the quality of defined external causes.

Hepatitis B Prevalence among Men Who Have Sex with Men in Brazil.

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.

Mortality surveillance in Brazil: factors associated with certification of unspecified external cause of death.

This article aims to analyze the association between characteristics of death - type of certifier and place of death - and the odds of an external cause death being certified as unspecified in Brazil. Cross-sectional study of deaths due to external causes from the Mortality Information System, 2017. Unspecified external cause (UEC) is the outcome variable in the models. Type of certifier physician, place of death and the interaction of these variables were the explanatory variables. Confounders were controlled by multiple logistic regression. UEC were the initial underlying cause for 22% of the 159,720 deaths from external causes in Brazil and 31% of hospital deaths issued by coroners. After adjustment for confounders, the odds of UEC in a hospital death certified by a coroner was 98% greater (OR=1.98; 95%CI: 1.53; 2.56) than in a home/street death issued by another certifier. This was greater than the odds for certifications by coroners (OR=1.23; 95%CI: 1.14; 1.33) and hospital deaths (OR=1.44; 95%CI: 1.32; 1.58). External causes certified by coroners and/or occurring in hospitals have a higher presence of UEC than other deaths; and indicate the need for coordinated initiatives by the health and public security sectors.

Primary Health Care in Northern and Northeastern Brazil: mapping team distribution disparities. / Atenção Primária à Saúde no Norte e Nordeste do Brasil: mapeando disparidades na distribuição de equipes.

This study analyzes the spatial pattern of implementation of Primary Health Care (PHC) teams in Northern and Northeastern Brazil. This is an ecological study on the rates of Community Health Workers (ACS), Family Health Team (eSF), Oral Health Team (eSB), and Family Health Extended Center (NASF) based on data from the Ministry of Health (MoH). The analysis of the area data identified patterns of spatial dependence of the municipalities for the rates, using Moran indices and scatterplots to visualize critical areas' clusters (95% confidence). Municipalities of the North (n=450) and Northeast (n=1,794) had 132,174 ACS, 18,405 eSF, 13,017 eSB, and 2,205 NASF. The proportion of municipalities with rates within the recommended by the MoH were: ACS (>1.33), 96% in the North and 98.5% in the Northeast; eSF (>2.9/1,000), 54% and 80% in the respective regions; eSB (>2.9/10,000) 28% and 59% in these respective regions. NASF teams were deployed in 70% of the North and 89% of the Northeast. Except for ACS, the North was a critical team area, mainly in Pará, Rondônia, Amazonas, and Amapá. In the Northeast, these areas were smaller and concentrated mainly in western Bahia and eastern Maranhão. The Northeast showed a better composition of teams and a smaller extent of critical areas.

Objetiva-se analisar o padrão espacial de implantação de equipes da Atenção Primária à Saúde (APS) no Norte e Nordeste do Brasil em 2017. Estudo ecológico das taxas de Agentes Comunitários de Saúde (ACS), equipes Saúde da Família (eSF), equipes Saúde Bucal (eSB) e Núcleo Ampliado de Saúde da Família (NASF), a partir de dados do Ministério da saúde (MS). A análise dos dados de área permitiu a identificação de padrões de dependência espacial dos municípios para as taxas, utilizando os índices e mapas de Moran para visualizar clusters de áreas críticas (95% de confiança). Os municípios do Norte (n=450) e Nordeste (n=1.794) apresentaram 132,2 mil ACS, 18,4 mil eSF, 13 mil eSB e 2,2 mil NASF. A proporção de municípios com taxas dentro do preconizado pelo MS: ACS (>1,33/mil) 96% no Norte e 98,5% no Nordeste; eSF (>2,9/10 mil) 54% e 80% nas respectivas regiões; eSB (>2,9/10 mil) 28% e 59% nestas respectivas regiões. Equipes NASF foram implantadas em 70% do Norte e 89% do Nordeste. Exceto ACS, a região Norte constituiu-se em área crítica de equipes, principalmente no Pará, Rondônia, Amazonas e Amapá. No Nordeste, essas áreas foram menores e concentradas a oeste da Bahia e leste do Maranhão. O Nordeste exibiu melhor composição de equipes e menor extensão de áreas críticas.

Proposal for classifying the different types of descriptive epidemiological studies. / Proposta de classificação dos diferentes tipos de estudos epidemiológicos descritivos.

Descriptive epidemiological studies are of relevance, given that there are inconsistencies in the literature with regard to their nomenclature and classification. We reviewed 19 international and six national academic textbooks on epidemiology, where the main criterion was to have them available in order to undertake an in-depth review of chapters on descriptive epidemiology and study types. In 11 books, the authors prioritize analytical studies. Twelve foreign texts and two from Brazil include descriptive studies, although the majority did not specifically refer to a category with this name. We propose a classification based on the answers to research questions, including the following types of study: case report, case series, clinical cohort, prevalence study, incidence study (cohort) and descriptive ecological study. We discuss potential uses, implementation of novel data analysis methods and their relevance in health surveillance.

A categoria dos estudos epidemiológicos descritivos é tema relevante, uma vez que existem inconsistências na literatura quanto a sua nomenclatura e classificação. Foram revistos livros de textos acadêmicos de epidemiologia, 19 estrangeiros e seis nacionais, sendo o critério principal tê-los disponíveis para revisão detalhada dos capítulos de epidemiologia descritiva e tipos de estudo. Em 11 livros, os autores dão prioridade aos estudos analíticos. Doze textos estrangeiros e dois brasileiros incluem estudos descritivos, apesar de a maioria não explicitar uma categoria específica com esse nome. Propõe-se uma classificação com base nas respostas a questões norteadoras de pesquisa, incluindo os seguintes tipos de estudos: relato de caso, série de casos, coorte clínica, estudo de prevalência, estudo de incidência (coorte) e estudo ecológico descritivo. Discutem-se as potencialidades do seu uso, a implementação de novos métodos de análise e sua relevância na vigilância à saúde.

Frequency and factors associated with recording deaths due to unspecified external causes in Brazil: a cross-sectional study, 2017. / Frequência e fatores associados ao registro inespecífico de óbitos por causas externas no Brasil: estudo transversal, 2017.

OBJECTIVE: To analyze the frequency and factors associated with recording deaths due to unspecified external causes in Brazil. METHODS: This was a cross-sectional study of Mortality Information System data for the year 2017. Univariate logistic regression was used to obtain odds ratios (OR) and 95% confidence intervals (95%CI) of nonspecific recording according to the explanatory variables - (hospital deaths and deaths certified by coroners). RESULTS: Brazil registered 159,720 deaths from external causes; 38.9% occurred in hospital, 83.4% were certified by coroners and 21.7% were from unspecified causes. Factors associated with the recording of unspecified external causes were hospital death (OR=2.00 - 95%CI 1.96;2.05) and the coroner's certification (OR=1.08 - 95%CI 1.04;1.11). CONCLUSION: The frequency of recording unspecified external causes is greater for hospital deaths than for coroner's certification.

Factors associated with knowledge and use of hiv prevention strategies among female sex workers in 12 brazilian cities. / Fatores associados ao conhecimento e utilização de estratégias de prevenção do HIV entre mulheres trabalhadoras do sexo em 12 cidades brasileiras.

This article aims to Identify factors associated with knowledge and use of combined HIV prevention strategies among female sex workers (FSW). Cross-sectional epidemiological study, using the Respondent Driven Sampling (RDS) method. Descriptive analyzes were performed after adjustments required by the RDS method. To investigate factors associated with knowledge of PEP and PrEP and use of the female condom, Poisson regression was applied, using odds ratio as an association measure. FSW not affiliated with NGOs, who did not receive informational material on prevention and / or participated in lectures in the last six months and who do not identify themselves as FSW in healthcare service facilities have less knowledge about PEP and PrEP and use the female condom less frequently. In general, FSW do not have sufficient knowledge and access to combined HIV prevention methods to take advantage of their benefits. We believe that the adoption of different models of care for FSW in partnership with NGOs can be an effective strategy for expanding knowledge and use of HIV prevention methods in Brazil.

O objetivo deste artigo é identificar fatores associados ao conhecimento e utilização de estratégias de prevenção combinada do HIV entre mulheres trabalhadoras do sexo (MTS). Estudo epidemiológico transversal, utilizando o método Respondent Driven Sampling (RDS). Foram realizadas análises descritivas após ajustes requeridos pelo método RDS. Para investigar fatores associados ao conhecimento de PEP e PrEP e utilização do preservativo feminino foi usada a regressão de Poisson, utilizando como medida de associação o Odds Ratio. MTS sem vínculo com ONGs, que não receberam material informativo sobre prevenção e/ou participaram de palestras nos últimos seis meses e que não se identificam como MTS nos serviços de saúde têm menos conhecimento sobre PEP e PrEP e utilizam com menor frequência o preservativo feminino. De maneira geral, as MTS não têm conhecimento e acesso suficiente às tecnologias de prevenção combinada do HIV a ponto de usufruir de seus benefícios. Consideramos que a adoção de modelos diferenciados de cuidados voltados para MTS em parceria com ONGs pode ser uma estratégia efetiva para ampliação do conhecimento e utilização das tecnologias de prevenção do HIV no Brasil.

[Syphilis in young Brazilian military recruits in 2016: sociodemographic, behavioral, and clinical aspects]. / Sífilis em jovens conscritos brasileiros, 2016: aspectos sociodemográficos, comportamentais e clínicos.

The objective was to characterize sociodemographic, behavioral, and clinical aspects in young Brazilian military recruits according to prevalence of syphilis. This was a descriptive study based on a nationwide population-based survey in 2016 with a probabilistic sample of military recruits 17 to 22 years of age. A confidential self-applied questionnaire was used. Blood samples were drawn from participants for treponemal and non-treponemal syphilis tests. Descriptive statistical techniques were used to estimate syphilis prevalence rates and distribution of frequencies between the target variables, considering 95% confidence intervals (95%CI), after weighting the data. Of the total of 37,282 participants, 73.7% were sexually initiated. Prevalence rates for lifetime and confirmed syphilis were 1.6% and 1.1%, respectively. The following population variables showed higher prevalence of syphilis: lack of Internet access at home; initiation of sexual activity before 14 years of age; men who have sex with men; more than five sexual partners; having received presents, drugs, or other incentives in exchange for sex; and prior history of symptoms of sexually transmissible infections. An increase was observed in syphilis in Brazilian military recruits when compared to previous surveys. This increase emphasizes the importance of this sentinel population for performing active surveillance in order to support healthcare strategies for youth, including in the school system.

O objetivo foi caracterizar aspectos sociodemográficos, comportamentais e clínicos entre conscritos brasileiros, segundo a prevalência de sífilis. Estudo descritivo desenvolvido valendo-se de pesquisa nacional de base populacional, realizada em 2016, com amostra probabilística de jovens conscritos de 17 a 22 anos de idade. Realizou-se autoaplicação de questionários confidenciais. As amostras de sangue total dos participantes foram coletadas para testagem de sífilis, com a utilização de testes treponêmicos e não treponêmicos. Empregaram-se técnicas de estatística descritiva para estimar as prevalências de sífilis e a distribuição de frequências entre as variáveis pesquisadas, considerando os intervalos de 95% de confiança (IC95%), após a ponderação dos dados. Do total de 37.282 participantes, 73,7% haviam iniciado a vida sexual. As prevalências de sífilis na vida e de sífilis confirmada foram de 1,6% e 1,1%, respectivamente. As seguintes variáveis populacionais apresentaram maior prevalência de sífilis: ausência de acesso à Internet no domicílio; início da atividade sexual antes dos 14 anos; categoria de exposição homens que fazem sexo com homens; práticas sexuais com mais de cinco parcerias; recebimento de presentes, drogas ou outros incentivos em troca de sexo; e história prévia de sintomatologia de infecções sexualmente transmissíveis. Observou-se o aumento de sífilis entre os jovens conscritos brasileiros, em comparação aos inquéritos anteriores. Tal incremento reforça a importância dessa população sentinela para realizar vigilância ativa, de forma a subsidiar estratégias de atenção à saúde dos jovens, incluindo cenários escolares.

Del total de 37.282 participantes, un 73,7% habían iniciado su vida sexual. Las prevalencias de sífilis en la vida y de sífilis confirmada fueron de 1,6% y 1,1%, respectivamente. Las siguientes variables poblacionales presentaron una mayor prevalencia de sífilis: ausencia de acceso a Internet en el domicilio; inicio de la actividad sexual antes de los 14 años; categoría de exposición hombres que practican sexo con hombres; prácticas sexuales con más de cinco personas; recibimiento de regalos, drogas u otros incentivos a cambio de sexo; e historia previa de sintomatología de infecciones sexualmente transmisibles. Se observó el aumento de sífilis entre los jóvenes reclutas brasileños, en comparación con las encuestas anteriores. Tal incremento refuerza la importancia de esa población centinela para realizar una vigilancia activa, de forma que se apoyen estrategias de atención a la salud de los jóvenes, incluyendo escenarios escolares.

[Trend and distribution of the homicide mortality rate in accordance with the size of the population of Brazilian municipalities - 2000 and 2015]. / Tendência e distribuição da taxa de mortalidade por homicídios segundo porte populacional dos municípios do Brasil, 2000 e 2015.

The scope of this study is to analyze the trends and distribution of homicide mortality rates (HMR) according to the population size of Brazilian municipalities between 2000 and 2015. It is an ecological study of deaths recorded in the Mortality Information System, with HMR standardized by the direct method and 95% confidence interval. HMR in Brazil grew 6% (to 29.1/100,000) in the period, with an increase in small municipalities (83%; 12.7 to 23.2/100,000) and mediumsized cities (52%; 19.7% to 30.1/100,000); which is true for both sexes, different ages, regions and firearm-related events. HMR decreased in major cities (19%; 40.6% to 32.9/100,000) and the Southeast region (55%; 45.6% to 20.6/100,000). The relative risk (RR) of small and medium-sized cities in relation to large cities is already greater than or close to 1 among women (RR 0.99; 1.03), people aged 60 years or older (RR 1.43; 1.36) and homicides by other means (RR 1.16; 1.18). The cities of São Paulo and Rio de Janeiro contributed the most to the reduction of HMR, especially in large cities (-37.6 and -22.3 homicides/100,000 inhabitants). Small and medium-sized municipalities have consistent trends of an increase in HMR even considering population subgroups.

O estudo tem como objetivo analisar tendências e distribuição das taxas de mortalidade por homicídios (TMH) segundo porte populacional dos municípios brasileiros entre 2000 e 2015. Trata-se de estudo ecológico dos óbitos do Sistema de Informações sobre Mortalidade, com TMH padronizada pelo método direto e intervalo de 95% de confiança. A TMH no Brasil cresceu 6% (para 29,1/100 mil) no período, com aumento em municípios de pequeno (83%; 12,7 para 23,2/100 mil) e médio porte (52%; 19,7 para 30,1/100 mil); o que se verifica para ambos os sexos, diferentes idades, regiões e em eventos por arma de fogo. A TMH decresceu em municípios de grande porte metropolitanos (19%; 40,6 para 32,9/100 mil) e da região Sudeste (55%; 45,6 para 20,6/100 mil). O risco relativo-RR de cidades pequenas e médias em relação a grandes já é maior ou próximo de 1 em mulheres (RR 0,99; 1,03), pessoas com 60 ou mais anos (RR 1,43; 1,36) e homicídios por outros meios (RR 1,16; 1,18). As cidades de São Paulo e Rio de Janeiro foram as que mais contribuíram para a redução das TMH, em especial nas cidades grandes (-37,6 e -22,3 homicídios/100 mil hab.). Municípios de porte pequeno e médio apresentam tendências consistentes de incremento de TMH mesmo considerando subgrupos populacionais.

[Expansion, displacement and interiorization of homicides in Brazil, between 2000 and 2015: a spatial analysis]. / Expansão, deslocamento e interiorização do homicídio no Brasil, entre 2000 e 2015: uma análise espacial.

The scope of this paper is to analyze the variation of the spatial pattern of the homicide rate in Brazil between 2000 and 2015. It is an ecological study by micro-regions of homicides taken from the Mortality Information System, using Moran indexes, and critical area clusters (95% CI). The rate increased by 6% (to 29.1/100,000 inhabitants (95% CI 28.9, 29.4), and in 80% of the micro regions between 2000 and 2015. The areas with high rates (> 38.2/100,000) increased 2.7-fold. In 2000, the highest rates were concentrated in areas in Pernambuco, São Paulo, Mato Grosso and Rio de Janeiro; by 2015, it will affect most states in the North and Northeast. The coastal regions of the Northeast and borders of Pará and Maranhão in the Amazon are critical areas. The lowest rate (19.1/100,000) is in São Paulo and Santa Catarina micro regions, with less critical clusters in the Southeast and South regions. Homicides have expanded into the interior of Brazil, with displacement between regions, mainly gravitating towards the poorest, which exhibit more critical areas in several scenarios, such as state borders and the coast. Conversely, there is marked contraction of homicides in states of highly developed regions with the presence of less critical areas. Key words Homicide.

O objetivo do estudo é analisar a mudança do padrão espacial da taxa de mortalidade por homicídios (TMH) no Brasil, entre 2000 e 2015. Trata-se de estudo ecológico por microrregiões das TMH do Sistema de Informações sobre Mortalidade, utilizando os índices de Moran e clusters de áreas críticas (95% de confiança). A TMH cresceu 6% (para 29,1/100 mil hab.; IC95% 28,9; 29,4), e em 80% das microrregiões entre 2000 e 2015. O número de áreas com altas TMH (> 38,2/100 mil) aumentou 2,7 vezes. Em 2000, as áreas com TMH mais altas concentravam-se em Pernambuco, São Paulo, Mato Grosso e Rio de Janeiro; em 2015, passam a ocupar estados das regiões Norte e Nordeste. As áreas mais críticas estão no litoral do Nordeste e nas fronteiras do Pará e Maranhão na Amazônia Legal. As menores TMH (até 19,1/100 mil) estão mais presentes nas microrregiões de São Paulo e Santa Catarina, com aglomerados menos críticos nas regiões Sudeste e Sul. O homicídio se expandiu para dentro do território nacional, com deslocamento entre regiões, em direção principalmente às mais pobres, que mostram áreas mais críticas em cenários distintos, como fronteiras de estados e litoral. Inversamente, há contração expressiva do homicídio em estados de regiões de desenvolvimento alto, com presença de áreas menos críticas.

Health Academy Program: correlation between noncommunicable chronic disease hospitalizations and program adherence in Brazilian municipalities, 2011-2017. / Programa Academia da Saúde: correlação entre internações por doenças crônicas não transmissíveis e adesão nos municípios brasileiros, 2011-2017.

OBJECTIVE: To analyze the correlation between municipalities adhering to the Health Fitness Center Program, noncommunicable chronic disease (NCD) hospitalizations and socioeconomic levels from 2011 to 2017. METHODS: This was an ecological study; HFCP adherence indicators for 2,837 municipalities were calculated, as were NCD hospitalization indicators, according to funding categories and the Firjan Socioeconomic Development Index. RESULTS: The HFCP adherence indicator was higher for municipalities that received Congress funding (1.18), had moderate to high Firjan Socioeconomic Development Indices (0.94) and high NCD hospitalization indicators (1.03) (p<0.001). There were positive correlations (p<0.05) between the two indicators in municipalities receiving Ministry of Health funding (r=0.14) and those receiving both Congress and Ministry of Health funding (r=0.12); whereas correlation was negative in municipalities with moderate to low Firjan Socioeconomic Development Indices (r=-0.09; p=0.013). CONCLUSION: The main form of adherence to the HFCP, according to population size, was through Congress funding. Municipalities with poorer socioeconomic and NCD indicators had lower adherence to the HFCP.

Workers' Health in Brazil: Accidents recorded by Social Security from 2008 to 2014.

OBJECTIVES: to analyze the incidence of occupational accidents in Brazil, recorded by Social Security according to the geographic regions, age group, gender and their prevalence according to the causes and branch of economic activity. METHODS: ecological descriptive study with time series analysis from 2008 to 2014. Data on the beginning and end of the historical series were compared in each ecological unit studied. RESULTS: the South and Southeast regions, male, between 20 and 49 years of age presented the highest falls in incidence. 70.87% of the causes occurred in group XIX of ICD-10. The economic activity with the highest prevalence of accidents was the manufacturing industry. CONCLUSIONS: accidents at work have decreased in Brazil, however, the incidence is still high. Advances need to be made in the recording of accidents and in the prevention and surveillance of workers' health.

Human rabies in Brazil: a descriptive study, 2000-2017. / Raiva humana no Brasil: estudo descritivo, 2000-2017.

OBJECTIVE: to describe the epidemiological profile of human rabies in Brazil. METHODS: this is a descriptive study of human rabies cases reported in 2000-2017, with an estimate of incidence and spatial distribution. RESULTS: 188 cases were studied, mostly males (66.5%), rural residents (67.0%), children under 15 years (49.6%), with biting being the most frequent form of exposure (81.9%); frequency was highest in the period 2000-2008 (85.6%), with 46.6% of cases involving dogs and 45.9% bats; median incubation was 50 days, followed by, predominantly, symptoms of fever (92.6%), agitation (85.2%), paresthesia (66.7%), and dysphagia/paralysis (51.9%); the majority (70.2%) did not have prophylaxis and for the rest (29.8%) who did have prophylaxis, it was untimely and/or incomplete; 13 patients were treated according to the Recife Protocol, and two survived. CONCLUSION: human rabies incidence reduced and its epidemiological profile changed, with predominance of cases transmitted by bats; we suggest that secondary cases be investigated, and that pre-exposure prophylaxis be made available to populations at greater risk of accidents involving bats.

Characteristics of hormone use by travestis and transgender women of the Brazilian Federal District.

INTRODUCTION: Travestis and transgender women resort to the use of hormones for body modification. Due to restrictions in the access to health services, self-medication is frequent. The aim of this study was to describe the self-reported prevalence of hormones used by travestis and transgender women in the Federal District. Method: This is a cross-sectional study with Respondent Driven Sampling (RDS) and Knowledge, Attitudes and Practices questionnaire (KAP) along with travestis and transgender women over 18 years in the FD. Prevalence was calculated using the RDS-II estimator. Logistic models were used to investigate the associated factors. A total of 201 volunteers participated. RESULTS: There was a young sample (median age of 24 years). The overall prevalence of continuous use of hormones was 64.5%. The most used formulation was the combination of estrogen and progesterone (86.2%) by injectable (75.1%) and oral (66%) administration. Most participants (84%) got the hormones without a prescription. Guidance on the use of these hormones came from their peers in 41% of the cases. We observed that the continuous use of hormones is associated with race, income and age, as well as the search for guidance of healthcare professionals, which is also associated with schooling. DISCUSSION: The reality of the process of hormone use by these people in the quest for femininity is reflected in high rates of self-medication. CONCLUSION: This study contributes to the visibility of the need to improve the access conditions of these people to health services.

Improvement of the unspecified external causes classification based on the investigation of death in Brazil in 2017. / Melhoria da classificação das causas externas inespecíficas de mortalidade baseada na investigação do óbito no Brasil em 2017.

BACKGROUND: Unspecified causes of death are among the traditional indicators of quality of information. OBJECTIVE: To verify the performance of the 60 cities in the Data for Health Initiative project and to analyze the reclassification of unspecified external causes of death (UEC). METHODS: Using the 2017 records from the Mortality Information System, the proportion and percent change in UEC were compared after investigation between project cities and other cities, and the percent of reclassification to specific external causes was calculated. RESULTS: The project cities comprised 52% (n = 11,759) of the total UEC in Brazil, of which 64.5% were reclassified after investigation, whereas the other cities reclassified 31% of UEC. Results were similar for men, youth, blacks, metropolitan cities, the Southeast region, and deaths attested by forensic institutes. In the project cities, pedestrian traffic accidents were external causes with greater reclassification. In men, the UEC was reclassified to homicides (23.8%) and accident of terrestrial transportation (ATT) (11.1%), with motorcyclists (4.4%) and pedestrians (4.3%) being the most prominent. In women, these causes were changed to other accident causes (20.8%), ATT (10.6%) and homicides (7.9%). UEC changed to ATT (18.3%) in the age groups of 0-14 years old and to homicides (32.5%) in the age groups of 15-44 years. CONCLUSION: The project cities obtained better results after investigation of UEC, enabling analysis of the reclassification to specific causes by sex and age groups.

INTRODUÇÃO: Causas inespecíficas de mortalidade estão entre os indicadores tradicionais de qualidade da informação. OBJETIVO: Verificar o desempenho das 60 cidades do projeto Dados para a Saúde e analisar a reclassificação das causas externas inespecíficas de mortalidade (CEI). MÉTODOS: A partir de registros de 2017 do Sistema de Informações sobre Mortalidade, comparou-se proporções e variações percentuais após investigação das CEI, entre cidades do projeto e demais cidades, e calculou-se percentual de reclassificação para causas específicas. RESULTADOS: As cidades do projeto concentraram 52% (n = 11.759) das CEI do Brasil, das quais 64,5% foram reclassificadas após investigação, enquanto as demais cidades reclassificaram 31%. Resultados foram semelhantes para homens, jovens, negros, cidades metropolitanas, região Sudeste, e em eventos atestados por institutos forenses. Nas cidades do projeto, acidentes de pedestres foram causas com maior reclassificação. Em homens, as CEI migraram para homicídios (23,8%) e acidentes de transporte terrestre (ATT) (11,1%), com destaque para motociclistas (4,4%) e pedestres (4,3%). Em mulheres, essas causas foram alteradas para outras causas acidentais (20,8%), ATT (10,6%) e homicídios (7,9%). CEI migraram para ATT (18,3%) no grupo de idade de 0 a 14 anos, e homicídios (32,5%) no grupo de 15 a 44 anos. CONCLUSÃO: As cidades do projeto obtiveram melhores resultados após investigação de CEI, possibilitando analisar a reclassificação para causas específicas, por sexo e faixas etárias.

The 12 city HIV Surveillance Survey among MSM in Brazil 2016 using respondent-driven sampling: a description of methods and RDS diagnostics.

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.
