Association between Adiposity Indexes and Kidney Disease: Findings from the Longitudinal Study of Adult Health (Elsa-Brazil).

INTRODUCTION: Chronic kidney disease (CKD) is a public health problem and it is associated with a high risk of mortality. Overweight and obesity are known as independent risk factors for CKD. OBJECTIVE: To investigate the association between adiposity indexes and kidney disease. METHODS: This study included 14,636 adults from ELSA-Brazil. Outcome variables: altered glomerular filtration rate (GFR), categorized as yes (GFR <60 mL/min/1.73 m2) and no (GFR ≥60 mL/min/1.73 m2), albuminuria, estimated by albumin-creatinine ratio and categorized as yes (≥30 mg/g) and no (<30 mg/g), and presence of chronic kidney disease (CKD) (altered GFR and/or albuminuria). Exposure variables: obesity and overweight (body mass index (BMI)≥30 and ≥25 kg/m2, respectively), high waist circumference (WC) (≥102 cm in men and ≥88 cm in women), high waist-to-hip ratio (WHR) (≥0.90 in men and ≥0.85 in women), and high waist-to-height ratio (WHtR) (≥0.5). To estimate the association between main exposures and outcomes, logistic regression analyses were performed using models adjusted for sociodemographic variables (age, gender, race/skin color, education), behavioral (smoking, physical activity, alcohol consumption), components of the metabolic syndrome (HDL cholesterol, triglycerides, hypertension, diabetes mellitus) and history of cardiovascular disease (myocardial infarction, angina or heart failure). RESULTS: Individuals with obesity, high WC, WHR and WHtR were more prone to albuminuria when compared to individuals with normal values for these measures. It was also observed that these altered measures were positively associated with the presence of CKD. CONCLUSION: Adiposity indexes have a direct and significant association with albuminuria and CKD.

Factors associated with chronic kidney disease, according to laboratory criteria of the National Health Survey. / Fatores associados à doença renal crônica segundo critérios laboratoriais da Pesquisa Nacional de Saúde.

OBJECTIVE: To identify the prevalence of glomerular filtration rate (GFR) less than 60 mL/min/1.73 m2 in Brazil and the associated factors. METHODS: This is a cross-sectional household-based epidemiological survey. Data were collected from the National Health Survey (PNS), conducted in 2013, by carrying out creatinine blood test and GFR calculation (n = 7,457). The groups of explanatory variables were: sociodemographic characteristics, lifestyles, chronic diseases, anthropometry, and health assessment. The prevalence of GFR < 60 mL/min/1.73 m2 and the respective 95% confidence intervals were estimated using the Poisson regression to calculate the crude and adjusted prevalence ratio (PR and adjPR) by age, sex, education level, and region. RESULTS: The prevalence of GFR < 60 mL/min/1.73 m2 was 6.48% (95%CI 5.88 - 7.09). After the adjustment, the following aspects remained associated: women (PR = 1.40; 95%CI 1.16 - 1.68), age of 45-59 years (adjPR = 7.27; 95%CI 3.8 - 14.1), 60 years or older (adjPR = 33.55; 95%CI 17.8 - 63.4), obesity (PR = 1.32 (95%CI 1.1 - 1.7), diabetes (PR = 1.44; 95%CI 1.2 - 1.8), poor/very poor self-rated health (PR = 1.50; 95%CI 1.2 - 1.9); and the lowest adjPR was found for the Northeast and Southeast regions, among smokers with high salt intake. CONCLUSION: GFR < 60 mL/min/1.73 m2 was higher in women, increased with age, in addition to being associated with obesity, diabetes, and poor self-rated health. Knowing the prevalence of chronic kidney disease through biochemical tests and risk and protective factors are paramount to support public health policies.

OBJETIVO: Identificar a prevalência da taxa de filtração glomerular estimada pelo clearance da creatinina endógena (estimativa da taxa de filtração glomerular - eTFG) menor que 60 mL/min/1,73 m2 no Brasil e os fatores associados. MÉTODOS: Trata-se de um inquérito epidemiológico transversal de base domiciliar. Os dados foram obtidos em subamostra de participantes da Pesquisa Nacional de Saúde (PNS), realizada em 2013, na qual foi feita coleta de sangue para medida de creatinina plasmática e calculado a eTFG (n = 7.457). Os grupos de variáveis explicativas foram: características sociodemográficas, estilos de vida, doenças crônicas, antropometria e avaliação de saúde. Foram estimadas as prevalências de eTFG < 60 mL/min/1,73 m2 e os respectivos intervalos de confiança de 95% (IC95%) utilizando a regressão de Poisson para calcular a razão de prevalência bruta (RPb) e ajustada (RPaj) por idade, sexo, escolaridade e região. RESULTADOS: A prevalência de eTFG < 60 mL/min/1,73 m2 foi de 6,48% (IC95% 5,88 - 7,09). Após ajuste, mantiveram-se associados: sexo feminino (RP = 1,40; IC95% 1,16 - 1,68), idade 45-59 anos (RPaj = 7,27; IC95% 3,8 - 14,1), 60 anos ou mais (RPaj = 33,55; IC95% 17,8 - 63,4), obesidade (RP = 1,32; IC95% 1,1 - 1,7), diabetes (RP = 1,44; IC95% 1,2 - 1,8), autoavaliação de saúde ruim/muito ruim (RP = 1,50; IC95% 1,2 - 1,9); menor RPaj foi encontrado nas regiões Nordeste e Sudeste, entre fumantes e com consumo elevado de sal. CONCLUSÃO: eTFG < 60 mL/min/1,73 m2 foi mais elevada no sexo feminino, aumentou com a idade, foi associada com obesidade, diabetes e pior avaliação de saúde. O conhecimento da prevalência da doença renal crônica, por meio de exames bioquímicos e dos fatores de risco e proteção, é essencial para subsidiar políticas públicas de saúde.

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.

ACCIDENTAL POISONING IN CHILDREN AND ADOLESCENTS ADMITTED TO A REFERRAL TOXICOLOGY DEPARTMENT OF A BRAZILIAN EMERGENCY HOSPITAL.

OBJECTIVE: To describe the profile of children and adolescents admitted for exogenous unintentional poisoning in the emergency room and analyze factors associated with subsequent in-hospital admissions. METHODS: This is a cross-sectional study based on hospital records of all subjects up to 19 years-old admitted in 2013 at a specialized toxicology service on a major public emergency hospital due to unintentional intoxication (as reported). Accidents with poisonous animals and insects were excluded. Percentages and frequencies were calculated for the qualitative variables, and measures of central tendency and dispersion for the continuous quantitative variables. Multivariate analysis was performed using binary logistic regression to identify variables associated with subsequent in-hospital admissions. RESULTS: In 2013, 353 cases were reported. Poisonings were more frequent in children 0-4 years-old (72.5%) and in boys (55%). The vast majority was of dwellers of the Metropolitan Region of Belo Horizonte (83%), and 90% of the accidental poisonings occurred at home. 82.7% of the poisonings occurred by oral ingestion, especially of medicinal (36.5%) and cleaning products (29.4% of all poisonings). Only 12.2% of the cases resulted in hospitalization, and only one resulted in death. Residing outside Belo Horizonte (OR=5.20 [95%CI 2.37-11.44]) and poisoning by two or more products (OR=4.29 [95%CI 1.33-13.82]) were considered risk factors for hospitalization. CONCLUSIONS: Accidental poisonings occurred most frequently by ingestion of household medications and cleaning products, especially among children under 4 years-old. Preventive strategies should be primarily directed for this prevalent profile.

RESUMO Objetivo: Descrever o perfil dos atendimentos de crianças e adolescentes vítimas de intoxicações exógenas acidentais e os fatores associados às internações hospitalares. Métodos: Foi realizado um estudo transversal com base na revisão dos registros de todas as intoxicações acidentais de indivíduos com até 19 anos de idade, atendidos no setor de toxicologia de um hospital público de referência em 2013, excluídos os acidentes com animais peçonhentos e insetos. A intencionalidade da intoxicação foi baseada nos relatos. Foram calculadas percentagens e frequências para as variáveis qualitativas, e medidas de tendência central e de dispersão das variáveis quantitativas contínuas. Foi realizada análise múltipla, utilizando regressão logística binária para identificar as variáveis associadas à internação hospitalar das vítimas atendidas. Resultados: Em 2013, foram identificados 353 atendimentos em crianças e adolescentes. A faixa etária mais prevalente foi a de zero a quatro anos (72,5%), e predominaram indivíduos do sexo masculino (55%). A maioria dos atendimentos foi de pacientes residentes na região metropolitana (83%). Noventa por cento das intoxicações ocorreram nos domicílios; 82,7% se deram pela via oral, especialmente por medicamentos (36,5%) e produtos de limpeza (29,4% de todas as intoxicações). Resultaram em internações 12,2% dos casos, ocorrendo um único óbito. As variáveis associadas à internação foram: residir fora do município sede (razão de chances [OR]=5,20; intervalo de confiança de 95% [IC95%] 2,37-11,44) e o envolvimento de mais do que uma substância na intoxicação (OR=4,29; IC95% 1,33-13,82). Conclusões: O ambiente doméstico é o principal local em que ocorrem as intoxicações em crianças e adolescentes, especialmente por ingestão de medicamentos e produtos de limpeza e abaixo de quatro anos de idade. Esses achados justificam a priorização de ações preventivas direcionadas para esse perfil de acidentes.

Evaluation of a smartphone application to improve medical certification of the cause of death. / Avaliação de um aplicativo para smartphone para aprimoramento da certificação médica da causa da morte.

INTRODUCTION: A smartphone application named AtestaDO was developed to support physicians with medical certification of the cause of death. The objective of this study is to evaluate the acceptability of the app. METHODS: Physicians were invited to attend meetings on the proper certification of cause of death, and to evaluate the application in a national workshop in Natal (first stage) and in two large hospitals in Belo Horizonte (second and third stages). RESULTS: In Natal, 82% of 38 physicians had more than 20 years of experience and in Belo Horizonte, more than 67% of 58 physicians had less than 5 years of experience. The sections "Application interface", "How to certify the causes of death", "Practice with exercises" and "Other information for physicians" were positively evaluated by more than 50% of physicians in Belo Horizonte. In Natal, all sections were positively evaluated by at least 80% of participants. More than 70% of the participants in both Natal and the second stage of Belo Horizonte indicated they would possibly use AtestaDO to guide filling of a death certificate. The probability of using AtestaDO to teach classes on filling death certificates was 83.3% for Natal's physicians but less than 60% in Belo Horizonte. In the three stages, most physicians would recommend using the application to other colleagues. CONCLUSION: The evaluation of AtestaDO showed good acceptability. We expect that the use of this tool enables improvements in medical certification of causes of death.

Racial disparities in renal function: the role of racial discrimination. The Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).

BACKGROUND: Racial discrimination may play a significant role in higher incidence and poorer prognosis of chronic kidney disease among Black individuals. This study set out to investigate the association between racial discrimination and renal function and to estimate the contribution of racial discrimination to existing racial disparities in renal function. METHODS: A cross-sectional analysis using baseline data (2008-2010) of 14 355 participants (35-74 years) in the Brazilian Longitudinal Study of Adult Health cohort study. Renal function was estimated based on estimated glomerular filtration rates (eGFR) obtained by the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. Racial discrimination was assessed using a modified version of the Lifetime Major Events Scale ; race/colour was self-reported. Covariates included were age, sex, level of education and selected health-related factors. RESULTS: Racial discrimination was reported by 31.6%, 6.3% and 0.8% of Black, Brown and White individuals, respectively. The older the age, the lower the prevalence of racial discrimination among Blacks. Racial discrimination was independently associated with lower mean eGFR (ß=-2.38; 95% CI -3.50 to -1.25); however, associations were limited to individuals aged under 55 years. In this age group, eGFR differences between Black and White individuals were reduced by 31% when exposure to racial discrimination was accounted for. CONCLUSION: Blacks are approximately 40 times more likely to report racial discrimination than Whites. Racial discrimination was associated with lower mean eGFR and explained a significant portion of eGFR differences between Black and White individuals aged under 55 years. Exposure to experiences of racial discrimination should be accounted for in studies investigating racial disparities in renal function.

First stages chronic kidney disease have mild effects on cognitive performance. Results of a 15,105 brazilian adult baseline cohort.

INTRODUCTION: The aging of the population may lead to an increased prevalence of dementia and chronic kidney disease (CKD) and their overlap. OBJECTIVE: We investigated the association between CKD and cognitive performance among Brazilian adults (35-74 years). METHODS: Baseline data analysis of the Longitudinal Study of Adults (ELSA-Brasil), a multicenter cohort comprising 15,105 civil servants, was performed. Kidney function was defined by the CKD-Epi-estimated GRF and albumin creatinin ratio (ACR). Cognitive performance was measured across tests that included the word memory tests, verbal fluency tests and Trail Making Test B. Multiple logistic and linear regressions were used to investigate the association between CKD and global as well as test-specific lowered cognitive performance. RESULTS: More than 90% of participants did not present CKD even considering reduced GFR or increased ACR simultaneously. Lowered cognitive performance was detected among 15.8% of the participants and mean values of GFR were slightly higher among those with normal than with lowered cognitive performance (86 ± 15 mL/min/1.73 m2 x 85 ± 16 mL/min/1.73 m2, p < 0.01). Age, education, skin-color, smoking, drinking, hypertension, and diabetes were associated with lowered cognition. After adjustment for these variables, there was no association between CKD and lowered cognitive performance. Negligibly small beta values were observed when analyzing CKD and the scores of all tests. CONCLUSION: These results suggest that cognitive performance remains preserved until renal function reaches significant worsening. Preventive measures to maintain renal function may contribute to the preservation of cognitive function.

Resumo Introdução: o envelhecimento da população pode levar a uma maior prevalência de demência, doença renal crônica (DRC) e da coexistência dessas doenças. Objetivo: investigamos a associação entre DRC e desempenho cognitivo em adultos brasileiros (35-74 anos). Métodos: análise de dados da linha de base do Estudo Longitudinal em Adultos (ELSA-Brasil), uma coorte multicêntrica envolvendo 15.105 funcionários públicos. A função renal foi definida pela TFG estimada CKD-Epi e pela razão albumina/creatinina (RAC). O desempenho cognitivo foi medido em avaliações que incluíram testes de memória de palavras, testes de fluência verbal e Teste de trilhas, versão B (Teste de Trilhas). Regressões logísticas e lineares múltiplas foram usadas para investigar a associação entre DRC e desempenho cognitivo global, bem como desempenho cognitivo reduzido em testes específicos. Resultados: Mais de 90% dos participantes não apresentaram DRC, mesmo considerando redução da TFG ou RAC aumentada, simultaneamente. O desempenho cognitivo reduzido foi detectado entre 15,8% dos participantes e os valores médios da TFG foram discretamente maiores entre os que apresentam desempenho cognitivo normal (86 ± 15 mL/min 1,73 m2 x 85 ± 16 mL/min/1,73 m2, p < 0,01). A idade, nível educacional, a cor da pele, o tabagismo, o consumo de álcool, a hipertensão e o diabetes estavam associados à cognição reduzida. Após o ajuste para essas variáveis, não houve associação entre DRC e desempenho cognitivo reduzido. Foram observados valores beta insignificantes ao analisar a DRC e as pontuações de todos os testes. Conclusão: estes resultados sugerem que o desempenho cognitivo permanece preservado até a função renal atingir piora significativa. Medidas preventivas para manter a função renal podem contribuir para a preservação da função cognitiva.

Cause-specific mortality for 249 causes in Brazil and states during 1990-2015: a systematic analysis for the global burden of disease study 2015.

BACKGROUND: Reliable data on cause of death (COD) are fundamental for planning and resource allocation priorities. We used GBD 2015 estimates to examine levels and trends for the leading causes of death in Brazil from 1990 to 2015. METHODS: We describe the main analytical approaches focused on both overall and specific causes of death for Brazil and Brazilian states. RESULTS: There was an overall improvement in life expectancy at birth from 1990 to 2015, but with important heterogeneity among states. Reduced mortality due to diarrhea, lower respiratory infections, and other infectious diseases contributed the most for increasing life expectancy in most states from the North and Northeast regions. Reduced mortality due to cardiovascular diseases was the highest contributor in the South, Southeast, and Center West regions. However, among men, intentional injuries reduced life expectancy in 17 out of 27 states. Although age-standardized rates due to ischemic heart disease (IHD) and cerebrovascular disease declined over time, these remained the leading CODs in the country and states. In contrast, leading causes of premature mortality changed substantially - e.g., diarrheal diseases moved from 1st to 13th and then the 36th position in 1990, 2005, and 2015, respectively, while violence moved from 7th to 1st and to 2nd. Overall, the total age-standardized years of life lost (YLL) rate was reduced from 1990 to 2015, bringing the burden of premature deaths closer to expected rates given the country's Socio-demographic Index (SDI). In 1990, IHD, stroke, diarrhea, neonatal preterm birth complications, road injury, and violence had ratios higher than the expected, while in 2015 only violence was higher, overall and in all states, according to the SDI. CONCLUSIONS: A widespread reduction of mortality levels occurred in Brazil from 1990 to 2015, particularly among children under 5 years old. Major shifts in mortality rates took place among communicable, maternal, neonatal, and nutritional disorders. The mortality profile has shifted to older ages with increases in non-communicable diseases as well as premature deaths due to violence. Policymakers should address health interventions accordingly.

Mortality and years of life lost by interpersonal violence and self-harm: in Brazil and Brazilian states: analysis of the estimates of the Global Burden of Disease Study, 1990 and 2015. / Mortalidade e anos de vida perdidos por violências interpessoais e autoprovocadas no Brasil e Estados: análise das estimativas do Estudo Carga Global de Doença, 1990 e 2015.

OBJECTIVE:: To analyze mortality and years of life lost due to death or disability (disability-adjusted life years - DALYs) for interpersonal violence and self-harm, comparing 1990 and 2015, in Brazil and Federated Units, using estimates produced by the Global Burden of Disease 2015 (GBD 2015). METHODS:: Secondary data analysis of estimates from the GBD 2015, producing standardized death rates and years of life lost due to death or disability. The main source of death data was the Mortality Information System, submitted to correction of underreporting of deaths and redistribution of garbage codes. RESULTS:: From 1990 to 2015, homicide mortality rates were stable, with a percentage variation of -0.9%, from 28.3/100 thousand inhabitants (95% UI 26.9-32.1) in 1990 to 27.8/100,000 (95% UI 24.3-29.8) in 2015. Homicide rates were higher in Alagoas and Pernambuco, and there was a reduction in São Paulo (-40.9%). Suicide rates decreased by 19%, from 8.1/100,000 (95% UI 7.5-8.6) in 1990 to 6.6/100,000 (95% UI 6.1-7,9) in 2015. Higher rates were found in Rio Grande do Sul. In the ranking of external causes for years of life lost due to death or disability (DALYs), firearm aggression predominated, followed by transportation accidents; self-inflicted injuries were in sixth place. CONCLUSIONS:: The study shows the importance of external causes among young people and men as a cause of premature death and disabilities, which is a priority problem in the country. The Global Burden of Disease study may support public policies for violence prevention.

Road traffic accidents: Global Burden of Disease study, Brazil and federated units, 1990 and 2015. / Acidentes de transporte terrestre: estudo Carga Global de Doenças, Brasil e unidades federadas, 1990 e 2015.

OBJECTIVE:: To describe the global burden of disease due to road traffic accidents in Brazil and federated units in 1990 and 2015. METHODS:: This is an analysis of secondary data from the 2015 Global Burden of Disease study estimates. The following estimates were used: standardized mortality rates and years of life lost by death or disability, potential years of life lost due to premature death, and years of unhealthy living conditions. The Mortality Information System was the main source of death data. Underreporting and redistribution of ill-defined causes and nonspecific codes were corrected. RESULTS:: Around 52,326 deaths due to road traffic accidents were estimated in Brazil in 2015. From 1990 to 2015, mortality rates decreased from 36.9 to 24.8/100 thousand people, a reduction of 32.8%. Tocantins and Piauí have the highest mortality risks among the federated units (FU), with 41.7/100 and 33.1/100 thousand people, respectively. They both present the highest rates of potential years of life lost due to premature deaths. CONCLUSION:: Road traffic accidents are a public health problem. Using death- or disability-adjusted life years in studies of these causes is important because there are still no sources to know the magnitude of sequelae, as well as the weight of early deaths. Since its data are updated every year, the Global Burden of Disease study may provide evidence to formulate traffic security and health attention policies, which are guided to the needs of the federated units and of different groups of traffic users.

RESUMO: Objetivo: Analisar a mortalidade e os anos de vida perdidos por morte ou incapacidade (Disability-Adjusted Life Years - DALYs) por violências interpessoais e autoprovocadas, comparando 1990 e 2015, no Brasil e nas Unidades Federadas, utilizando estimativas produzidas pelo estudo Carga Global de Doença 2015 (GBD 2015). Métodos: Análise de dados secundários das estimativas do GBD 2015, com produção de taxas padronizadas de mortes e DALYs. A principal fonte de dados de óbitos foi o Sistema de Informações sobre Mortalidade, submetido à correção do sub-registro de óbitos e redistribuição de códigos garbage. Resultados: De 1990 a 2015, observou-se estabilidade das taxas de mortalidade por homicídios, com variação percentual de -0,9%, passando de 28,3/100 mil habitantes (II 95% 26,9-32,1), em 1990, para 27,8/100 mil (II 95% 24,3-29,8), em 2015. As taxas de homicídio foram mais altas em Alagoas e Pernambuco, e ocorreu redução em São Paulo (-40,9%). As taxas de suicídio variaram em -19%, saindo de 8,1/100 mil (II 95% 7,5-8,6), em 1990, para 6,6/100 mil (II 95% 6,1-7,9), em 2015. Taxas mais elevadas ocorreram no Rio Grande do Sul. No ranking de causas externas por Disability-Adjusted Life Years (DALYs), predominaram as agressões por arma de fogo, seguidas de acidentes de transporte e em sexto lugar lesões autoprovocadas. Conclusões: O estudo aponta a importância das causas externas entre jovens e homens na morte prematura e em incapacidades, constituindo um problema prioritário no país. O estudo Carga Global de Doença poderá apoiar políticas públicas de prevenção de violência.

Acidentes de transporte terrestre: estudo Carga Global de Doenças, Brasil e unidades federadas, 1990 e 2015 / Road traffic accidents: Global Burden of Disease study, Brazil and federated units, 1990 and 2015

RESUMO: Objetivo: Descrever a carga global dos acidentes de transporte terrestres no Brasil e Unidades Federadas, em 1990 e 2015. Métodos: Análise dos dados secundários das estimativas do estudo Carga Global de Doenças 2015. Utilizam-se as estimativas de taxas padronizadas de mortalidade e anos de vida perdidos por morte ou incapacidade, anos potenciais de vida perdidos por morte prematura, e anos de vida não saudáveis. O Sistema de Informações sobre Mortalidade foi a principal fonte de dados de óbitos. Houve a correção do sub-registro e ajustes por códigos garbage. Resultados: No ano de 2015 foram estimados 52.326 óbitos por acidentes de transportes terrestres no Brasil. De 1990 a 2015, as taxas de mortalidade diminuíram de 36,9 para 24,8/100 mil habitantes, redução de 32,8%. Tocantins e Piauí têm os maiores riscos de mortalidade entre as unidades federadas (UF), com 41,7 e 33,1/100 mil, respectivamente. Ambos também têm as maiores taxas de anos potenciais de vida perdidos por morte prematura. Conclusão: Os acidentes de transportes terrestres constituem um problema de saúde pública. Utilizar anos de vida perdidos ajustados por morte ou incapacidade nos estudos dessas causas é importante, pois não existem fontes para conhecer a magnitude da incapacidade nem o peso das mortes precoces. O estudo Carga Global de Doenças, ao atualizar os dados anualmente, poderá fornecer evidências para a formulação de políticas de segurança no trânsito e de atenção à saúde, orientadas para as necessidades das UF e de diferentes grupos de usuários do trânsito.

Thyrotropin levels are associated with chronic kidney disease among healthy subjects in cross-sectional analysis of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).

BACKGROUND: Few studies have evaluated a possible relationship between thyrotropin levels and glomerular filtration rate (GFR) and albumin/creatinine ratio in euthyroid subjects. We aimed to analyze this association using baseline data from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). METHODS: Cross-sectionally, we included subjects with normal thyroid function and with subclinical hypothyroidism (SCH). We excluded individuals using medications that affect thyroid function. Linear and logistic regression models evaluated GFR estimated by Chronic Kidney Disease Epidemiology Collaboration (CKD-Epi) and albuminuria/creatinine ratio as dependent variables and thyrotropin quartiles in individuals with euthyroidism and SCH as independent variables, adjusted for demographical characteristics and diseases related to CKD. RESULTS: We included 13,193 subjects with a median age of 51 years [interquartile range, (IQR): 45-58], 6840 (51.8%) women, 12,416 (94.1%) euthyroid, and 777 (5.9%) with SCH. SCH subjects were characterized by higher age, triglycerides, frequency of white race, cardiovascular disease, CKD, and former smokers. In adjusted models, log-transformed TSH in euthyroid subjects was inversely and strongly associated with CKD (ß = -2.181, 95% CI -2.714 to -1.648), P < 0.0001 for glomerular filtration rate and 4.528 (1.190-7.865) for albuminuria/creatinine ratio. Multivariate logistic models for euthyroid subjects showed an OR of 1.45 (95% CI 1.15-1.83) for GFR and of 1.95 (95% CI 1.08-3.54) for albuminuria/creatinine ratio in the fourth quartile of TSH using the first as the reference. CONCLUSIONS: Thyrotropin levels are independently associated with CKD in euthyroid subjects.

Evaluating the Brazilian zero tolerance drinking and driving law: Time series analyses of traffic-related mortality in three major cities.

OBJECTIVE: A zero tolerance alcohol restriction law was adopted in Brazil in 2008. In order to assess the effectiveness of this intervention, the present study compares specific mortality in 2 time series: 1980-2007 and 2008-2013. METHODS: Data on mortality and population were gathered from official Brazilian Ministry of Health information systems. Segmented regression analyses were carried out separately for 3 major Brazilian capitals: Belo Horizonte, Rio de Janeiro, and São Paulo. RESULTS: In 2 cities (Belo Horizonte and Rio de Janeiro) there were no significant changes in mortality rate trends in 2 periods, 1980 to 2007 and 2008 to 2013, where the observed rates did not differ significantly from predicted rates. In São Paulo, a decreasing trend until 2007 unexpectedly assumed higher levels after implementation of the law. CONCLUSION: There is no evidence of reduced traffic-related mortality in the 3 major Brazilian capitals 5.5 years after the zero tolerance drinking and driving law was adopted.

Frequency of cholecystectomy and associated sociodemographic and clinical risk factors in the ELSA-Brasil study.

CONTEXT AND OBJECTIVE: There are few data in the literature on the frequency of cholecystectomy in Brazil. The frequency of cholecystectomy and associated risk factors were evaluated in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). DESIGN AND SETTING: Cross-sectional study using baseline data on 5061 participants in São Paulo. METHODS: The frequency of cholecystectomy and associated risk factors were evaluated over the first two years of follow-up of the study and over the course of life. A multivariate regression analysis was presented: odds ratio (OR) and 95% confidence interval (95% CI). RESULTS: A total of 4716 individuals (93.2%) with information about cholecystectomy were included. After two years of follow-up, 56 had undergone surgery (1.2%: 1.7% of the women; 0.6% of the men). A total of 188 participants underwent cholecystectomy during their lifetime. The risk factors associated with surgery after the two-year follow-up period were female sex (OR, 2.85; 95% CI, 1.53-5.32), indigenous ethnicity (OR, 2.1; 95% CI, 2.28-15.85) and body mass index (BMI) (OR, 1.10; 95% CI, 1.01-1.19 per 1 kg/m2 increase). The risk factors associated over the lifetime were age (OR, 1.03; 95% CI, 1.02-1.05 per one year increase), diabetes (OR, 1.92; 95% CI, 1.34-2.76) and previous bariatric surgery (OR, 5.37; 95% CI, 1.53-18.82). No association was found with parity or fertile age. CONCLUSION: Female sex and high BMI remained as associated risk factors while parity and fertile age lost significance. New factors such as bariatric surgery and indigenous ethnicity have gained importance in this country.

RESUMO CONTEXTO E OBJETIVO: Há escassez de dados na literatura sobre a frequência de colecistectomia no Brasil. Avaliou-se a frequência de colecistectomia e os fatores de risco associados no Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil). DESENHO E LOCAL: Estudo transversal com dados da linha de base de 5061 participantes em São Paulo. MÉTODOS: Avaliou-se a frequência de colecistectomia e fatores de risco associados nos dois primeiros anos de seguimento do estudo e ao longo da vida. Apresentou-se regressão logística [razão de chances (RC); intervalo de confiança de 95% (IC 95%)] multivariada. RESULTADOS: Um total de 4716 (93,2%) indivíduos com informação sobre colecistectomia foi incluído. Após 2 anos de seguimento, 56 participantes tinham sido operados (1,2%: 1,7% nas mulheres; 0,6% nos homens), totalizando 188 participantes com colecistectomia durante a vida. Os fatores de risco associados à cirurgia após dois dois anos de seguimento foram sexo feminino (RC, 2,85; IC 95%, 1,53-5,32), etnia indígena (RC, 2,1; IC 95%, 2,28-15,85) e índice de massa corpórea, IMC (RC, 1,10; IC 95%, 1,01-1,19 por aumento de 1 kg/m2); e, ao longo da vida: idade (RC, 1,03; IC 95%, 1,02-1,05 por um ano de aumento), diabetes (RC, 2,10; IC 95%, 1,34-2,76) e cirurgia bariátrica prévia (RC, 5.37; IC 95%, 1,53-18,82). Não se observou associação com paridade ou idade fértil. CONCLUSÃO: Sexo feminino e IMC elevado permanecem sendo fatores de risco associados à colecistectomia, mas paridade e idade fértil perderam significância. Novos fatores de risco, como cirurgia bariátrica prévia e etnia indígena, ganharam relevância no país.
