Factors Affecting Under-Five Mortality Rate (U5MR) in India- National Family Health Survey (NFHS) 5 Factsheet What It Speaks?

Introduction: In developing countries various factors lead to Under-5 Mortality and irreversible losses which can be prevented by proper measures take on factors affecting to it. Objective: This study was conducted to analyse the changing trends of Under-5 Mortality in India. The new National Family Health Survey (5th round) which was published recently came up with several new findings, which were both encouraging and disheartening and also one of the major Sustainable Development Goals.Method: A secondary data analysis was conducted of NFHS factsheets to study the U5MR in India. The indica-tors which had a correlation either positive or negative with the Under-five mortality rate were included.Result- When we look at the result, few states' performance is encouraging because they have shown some of the best declines. Correlation was found between dependant variable that is U5MR which is a dependent vari-able and several independent variables which concluded that factors like Women literacy, Men literacy, Breastfeeding, Nutritional insufficiencies, Caesarean delivery, ANC visits and IFA consumptions are negatively associated withU5MR. Conclusion: Various steps have been taken in order to improve our healthcare sector since independence, every government had their fair share of contribution, that’s the reason why we are this stage. Now it’s time to increase efforts with targeted interventions to solve this problem and complete our commitment towards the SDGs.

Sickle cell disease related mortality in Brazil, 2000-2018

Abstract Introduction There is a demand to update national mortality trends data related to sickle cell disease (SCD) in Brazil. This study describes causes of death and mortality issues related to SCD using the multiple-cause-of-death methodology. Methods The annual SCD mortality data was extracted from the public databases of the Mortality Information System by researching deaths in rubric D57 "sickle-cell disorders" of the International Classification of Diseases, Tenth Revision and processed by the Multiple Cause Tabulator. Results From 2000 to 2018 in Brazil, a total of 9817 deaths related to SCD occurred during the 19-year period, as the underlying cause in 6924 (70.5%) and as the associated cause of death in 2893 (29.5%). The mean and median ages at death during the entire period were significantly lower for males, 29.4 (±19.6) and 27.5 (15.5-41.5), respectively, than for females, 33.3 (±20.3) and 31.0 (19.5-46.5), respectively. The leading SCD overall associated causes of death were septicemias (32.1%), followed by pneumonias (19.4%) and respiratory failure (18.2%). On certificates with SCD as an associated cause, the underlying causes of death were circulatory system diseases (8.7%), followed, in males, by digestive system and infectious diseases and respiratory system failures, while in females, maternal deaths, included in the chapter on pregnancy, childbirth and the puerperium, accounting for 4.6% of female deaths, were succeeded by digestive system and infectious diseases. Conclusion This study revised mortality data on death rate trends, underlying and associated causes of death, age at death and regional distribution of death in Brazil.

Analysis of trends in sepsis mortality in Brazil and by regions from 2010 to 2019 / Análise de tendência de mortalidade por sepse no Brasil e por regiões de 2010 a 2019

ABSTRACT OBJECTIVE To characterize the profile of inpatients and trend of sepsis mortality in the Brazilian Unified Health System (SUS), throughout Brazil, and in its regions separately, from 2010 to 2019. METHODS Observational, analytical and retrospective study of secondary data obtained through consultation to the Sistema de Informação Hospitalar (Hospital Information System). All incoming septicemia notifications from January 1, 2010 to December 31, 2019 were included. The following sociodemographic variables were used: sex, age, race, region and federative unit of residence. For data analysis, we used mortality and hospitalization coefficient, relative risk and Joinpoint regression. RESULTS There were a total of 1,044,227 cases of sepsis in Brazil, yielding a mean prevalence coefficient of 51.3/100 thousand inhabitants. There were 463,000 deaths from sepsis recorded, with a mean prevalence coefficient of 22.8 deaths/100,000 inhabitants. The highest rates occurred among the elderly, of brown race, and there was no significant difference between genders. The Southeast region accounted for the highest rates of hospitalization and deaths. A general trend toward increased mortality was observed in the period studied. CONCLUSION The heterogeneity of Brazil should be considered regarding socioeconomic and demographic characteristics, and differences in health investment and underreporting between regions, in order to understand the disease's epidemiological course. Finally, these findings should be correlated with other studies, in an effort to understand the behavior of the disease, and provide inputs for public and private policies in order to reduce the expressiveness of cases and deaths from sepsis in Brazil.

RESUMO OBJETIVO Caracterizar o perfil dos pacientes internados e a tendência de mortalidade por sepse no Sistema Único de Saúde (SUS), em todo Brasil e em suas regiões separadamente, entre os anos de 2010 e 2019. MÉTODOS Estudo observacional, analítico e retrospectivo de dados secundários obtidos por consulta ao Sistema de Informação Hospitalar. Foram incluídas todas as notificações por septicemia admitidas entre 1 de janeiro de 2010 e 31 de dezembro de 2019. Utilizou-se as variáveis sociodemográficas: sexo, idade, raça, região e unidade federativa de residência. Para a análise dos dados, utilizou-se coeficiente de mortalidade e de internação, risco relativo e regressão por Joinpoints. RESULTADOS Totalizaram-se 1.044.227 casos de sepse no país, perfazendo um coeficiente de prevalência média de 51,3/100 mil habitantes. Foram registrados 463 mil óbitos por sepse, com coeficiente médio de 22,8 óbitos/100 mil habitantes. As maiores taxas ocorreram entre os idosos, de raça parda e não houve uma diferença significativa entre os sexos. A Região Sudeste foi responsável pelo maior índice de internação e óbitos. Observou-se uma tendência geral de aumento da mortalidade no período estudado. CONCLUSÃO Cabe considerar a heterogeneidade do Brasil, no que concerne às características socioeconômicas e demográficas e às diferenças de investimento em saúde e de subnotificações entre as regiões, a fim de entender o traçado epidemiológico da doença. Por fim, é necessário correlacionar esses achados com demais estudos, buscando entendimento do comportamento da doença e embasamento para políticas públicas e privadas, com intuito de diminuir a expressividade de casos e óbitos por sepse no país.

Mortality attributed to sickle cell disease in children and adolescents in Brazil, 2000-2019 / Mortalidade atribuída à doença falciforme em crianças e adolescentes no Brasil, 2000-2019

ABSTRACT OBJECTIVE Estimate rates and describe mortality trends attributed to sickle cell disease in children and adolescents in Brazil from 2000 to 2019. METHODS This is an ecological study of the time-trend of mortality rates that used the autoregressive method, proposed by Prais-Winsten, to evaluate trends in the estimated rates of sickle cell disease deaths in children and adolescents in Brazil. Deaths with code D57 were obtained from the Mortality Information System, considering age groups (0-4, 5-9, 10-14, 15-19 years) and were used to estimate age-specific and standardized rates by gender and age. RESULTS From 2000 to 2019, Brazil had 2,422 deaths from sickle cell disease in people under 20 years of age, with higher frequency in the Northeast (40.46%), followed by the Southeast (39.02%), Midwest (9.58%), North (7.84%), and South (3.10%). The main victims were people of Black skin/race (78.73%). In Brazil, the global standardized average rate was 0.20/100,000 people-year, with an elevation trend (annual percentage change - APC = 5.44%; confidence interval - 95%CI: 2.57-8.39). The pattern was repeated in males (APC = 4.38%; 95%CI: 2.17-6.64) and females (APC = 6.96%; 95%CI: 3.05-11.01). Elaborating age-specific rates showed that the range up to four years experienced the highest rates, without distinction by region. The age group of 15 and 19 years was the second most affected in Brazil and in the Northeast, Southeast, and Midwest regions. CONCLUSION Deaths due to sickle cell disorders showed an elevation trend in children and adolescents. Considering that the magnitude of deaths was more evident in the first years (0-4) and late adolescence (15-19), the study suggests that age-specific approaches may impact the control of fatal outcomes caused by sickle cell disease in Brazil.

RESUMO OBJETIVO Estimar taxas e descrever tendências de mortalidade atribuídas à doença falciforme em crianças e adolescentes no Brasil, de 2000 a 2019. MÉTODOS Este é um estudo ecológico do tipo séries temporais de taxas de mortalidade que usou o método autorregressivo, proposto por Prais-Winsten, para avaliar tendências das taxas estimadas de mortes por doença falciforme em crianças e adolescentes no Brasil. Os óbitos com código D57 foram obtidos no Sistema de Informações sobre Mortalidade, considerando as faixas etárias (0-4, 5-9, 10-14, 15-19 anos) e usados para estimar taxas específicas por idade e taxas padronizadas por sexo e idade. RESULTADOS De 2000 a 2019, houve 2.422 óbitos por doença falciforme em menores de 20 anos no Brasil, com maior frequência na região Nordeste (40,46%), seguida de Sudeste (39,02%), Centro-Oeste (9,58%), Norte (7,84%) e Sul (3,10%). As principais vítimas foram pessoas de raça/cor da pele negra (78,73%). No Brasil, a taxa média padronizada global foi de 0,20/100 mil pessoa-ano, com tendência de elevação (mudança percentual anual - APC = 5,44%; intervalo de confiança - IC95% 2,57-8,39). O padrão se repetiu no sexo masculino (APC = 4,38%; IC95% 2,17-6,64) e no sexo feminino (APC = 6,96%; IC95% 3,05-11,01). A elaboração de taxas específicas por idade mostrou que a faixa até quatro anos experimentou as maiores taxas, sem distinção por região. A faixa etária de 15 e 19 anos foi a segunda mais afetada no Brasil e nas regiões Nordeste, Sudeste e Centro-Oeste. CONCLUSÃO Houve tendência de aumento dos óbitos por transtornos falciformes em crianças e adolescentes. Considerando que a magnitude dos óbitos foi mais evidente nos primeiros anos (0-4) e no final da adolescência (15-19), o estudo sugere que abordagens específicas por faixa etária podem impactar no controle dos desfechos fatais causados pela doença falciforme no Brasil.

Mortality in Brazilian federal highway police officers: time series from 2001 to 2020 / Mortalidade em agentes da polícia rodoviária federal: série temporal entre 2001 e 2020

ABSTRACT OBJECTIVE To analyze the mortality trend from all causes in Brazilian federal highway police officers from 2001 to 2020. METHODS This is an ecological time-series study based on mortality official data from the Brazilian federal highway police registry system and death certificates from the federal registry system. Deaths of active police officers from 2001 to 2020 were assessed. We performed a descriptive analysis reporting proportions and incidence rates per 1,000 police officers. The chi-square test was used for bivariate analyzes and Prais-Winsten regression was used for trend analysis. RESULTS Among 346 deaths, 146 were from natural and 189 from unnatural causes (11 were from undefined causes). Most deaths occurred among police officers who were men (n = 333; 96.3%), over 35 years old (n = 265; 76.6%), whose service time was up to 15 years (n = 185; 53.5%), living in Northeast Brazil, and from unnatural causes (n = 189; 56.4%). The absolute number of deaths presented a decreasing trend throughout the series (p = -0.78; 95%CI: -1.03 to -0.5). Traffic accidents (n = 96; 28.7%), cardiovascular diseases (n = 58; 17.3%), interpersonal violence (n = 51; 15.2%), suicides (n = 35; 10.5%), and malignant neoplasms (n = 35; 10.4%) were the main causes of death. Most natural deaths occurred among police officers who were 51-73 years old (68.3%; 95%CI: 58.6 to 76.7) and worked more than 26 years (64.7%; 95%CI: 52.7 to 75.1), while most unnatural deaths occurred among officers who were 19-35 years old (87.3%; 95%CI: 78.0 to 93.1) and worked up to 15 years (70.2%; 95%CI: 63.1 to 76.4). CONCLUSION The mortality trend in Brazilian federal highway police officers decreased within the period studied. Understanding mortality causes may help to develop policies for disease prevention and health protection of police officers.

RESUMO OBJETIVO Descrever e analisar a tendência de mortalidade, por todas as causas, em agentes da polícia rodoviária federal, entre os anos de 2001 e 2020. MÉTODOS Trata-se de um estudo ecológico de séries temporais, baseado em dados oficiais sobre mortalidade registrados no sistema de cadastro nacional da polícia rodoviária federal e de certidões de óbitos do sistema de cadastro federal. Foram coletados os óbitos de agentes que estavam em efetivo exercício entre 2001 e 2020. Realizou-se análise descritiva, calcularam-se proporções e taxas de incidência por 1.000 policiais. Utilizou-se qui-quadrado para análises bivariadas e regressão de Prais-Winsten para análise de tendência. RESULTADOS Ocorreram 346 óbitos (11 por causas indeterminadas), dos quais 146 foram por mortes naturais e 189 não naturais. A maioria das mortes ocorreu em policiais do sexo masculino (n = 333; 96,3%), acima de 35 anos (n = 265; 76,6%), tempo de serviço até 15 anos (n = 185; 53,5%), da região Nordeste e por causas não naturais (n = 189; 56,4%). O número absoluto de óbitos de agentes apresentou tendência decrescente ao longo da série (p = -0,78; IC95% -1,03 - -0,5). Entre as principais causas de morte estão acidentes de trânsito (n = 96; 28,7%), doenças cardiovasculares (n = 58; 17,3%), violência interpessoal (n = 51; 15,2%), suicídio (n = 35; 10,5%) e neoplasias malignas (n = 35; 10,4%). As mortes naturais predominaram entre os agentes com idade entre 51-73 anos (68,3%; IC95% 58,6-76,7) e mais de 26 anos de serviço (64,7%; IC95% 52,7-75,1), já as não naturais, entre a faixa etária de 19-35 anos (87,3%; IC95% 78,0-93,1) e de até 15 anos de serviço (70,2%; IC95% 63,1-76,4). CONCLUSÕES Conclui-se que a tendência das mortes de agentes da polícia rodoviária federal foi decrescente no período. O conhecimento das causas de mortalidade pode auxiliar no desenvolvimento de políticas de prevenção de doenças e proteção à saúde desses policiais.

Mortality inequalities measured by socioeconomic indicators in Brazil: a scoping review

ABSTRACT OBJECTIVE Summarize the literature on the relationship between composite socioeconomic indicators and mortality in different geographical areas of Brazil. METHODS This scoping review included articles published between January 1, 2000, and August 31, 2020, retrieved by means of a bibliographic search carried out in the Medline, Scopus, Web of Science, and Lilacs databases. Studies reporting on the association between composite socioeconomic indicators and all-cause, or specific cause of death in any age group in different geographical areas were selected. The review summarized the measures constructed, their associations with the outcomes, and potential study limitations. RESULTS Of the 77 full texts that met the inclusion criteria, the study reviewed 24. The area level of composite socioeconomic indicators analyzed comprised municipalities (n = 6), districts (n = 5), census tracts (n = 4), state (n = 2), country (n = 2), and other areas (n = 5). Six studies used composite socioeconomic indicators such as the Human Development Index, Gross Domestic Product, and the Gini Index; the remaining 18 papers created their own socioeconomic measures based on sociodemographic and health indicators. Socioeconomic status was inversely associated with higher rates of all-cause mortality, external cause mortality, suicide, homicide, fetal and infant mortality, respiratory and circulatory diseases, stroke, infectious and parasitic diseases, malnutrition, gastroenteritis, and oropharyngeal cancer. Higher mortality rates due to colorectal cancer, leukemia, a general group of neoplasms, traffic accident, and suicide, in turn, were observed in less deprived areas and/or those with more significant socioeconomic development. Underreporting of death and differences in mortality coverage in Brazilian areas were cited as the main limitation. CONCLUSIONS Studies analyzed mortality inequalities in different geographical areas by means of composite socioeconomic indicators, showing that the association directions vary according to the mortality outcome. But studies on all-cause mortality and at the census tract level remain scarce. The results may guide the development of new composite socioeconomic indicators for use in mortality inequality analysis.

Causes of death and mortality trends related to hemophilia in Brazil, 1999 to 2016

ABSTRACT Introduction Multiple cause of death methodology enhances mortality studies beyond the traditional underlying cause of death approach. Aim: This study aims to describe causes of death and mortality issues related to haemophilia with the use of multiple-cause-of-death methodology. Methods: Annual male haemophilia mortality data was extracted from the public multiple-cause-of-death databases of the Mortality Information System, searching deaths included in rubrics D66 "hereditary factor VIII deficiency" (haemophilia A), and D67 "hereditary factor IX deficiency" (Haemophilia B) of the International Classification of Diseases, Tenth Revision, and processed by the Multiple Cause Tabulator. Results: In Brazil, from 1999 to 2016, a total of 927 male deaths related to haemophilia occurred during the 18 year period, of which 418 (45,1 %) as underlying cause, and 509 (54,9 %) as associated cause of death. The leading associated cause of 418 deaths of haemophilia as underlying cause was hemorrhage (52.6%), half of which intracranial hemorrhage. Infectious and parasitic diseases accounted for 40,5% as the underlying causes of 509 deaths where haemophilia was an associated cause, where human immunodeficiency virus disease prevailed, however falling from 37,0% to 19.7%, and viral hepatitis increased from 6.0% to 7.9%; diseases of the circulatory system, increased from 13.5% to 18.4%, including intracranial hemorrhage from 5.7% to 7.0%, and neoplasms, from 8,5% to 13.2%, respectively from 1999-2007 to 2008-2016, followed as main underlying causes. Conclusion: Hemorrhages, mainly intracranial hemorrhage, human immunodeficiency virus disease, and viral hepatitis are the chief prevention goals aiming at the control of haemophilia mortality.

Trends in abdominal aortic aneurysm-related mortality in Brazil, 2000-2016: a multiple-cause-of-death study

OBJECTIVES: Remarkable changes in the epidemiology of abdominal aortic aneurysm (AAA) have occurred in many countries during last few decades, which have also affected Brazilian mortality concurrently. This study aimed to investigate mortality trends related to AAA mortality in Brazil from 2000 to 2016. METHODS: Annual AAA mortality data was extracted from the public databases of the Mortality Information System, and processed by the Multiple Cause Tabulator. RESULTS: In Brazil, 2000 through 2016, AAA occurred in 69,513 overall deaths; in 79.6% as underlying and in 20.4% as an associated cause of death, corresponding to rates respectively of 2.45, 1.95 and 0.50 deaths per 100,000 population; 65.4% male and 34.6% female; 60.6% in the Southeast region. The mean ages at death were 71.141 years overall, and 70.385 years and 72.573 years for men and women, respectively. Ruptured AAA occurred in 64.3% of the deaths where AAA was an underlying cause, and in 18.0% of the deaths where AAA was an associated cause. The standardized rates increased during 2000-2008, followed by a decrease during 2008-2016, resulting in an average annual percent change decline of -0.2 (confidence interval [CI], -0.5 to 0.2) for the entire 2000-2016 period. As associated causes, shock (39.2%), hemorrhages (33.0%), and hypertensive diseases (26.7%) prevailed with ruptured aneurysms, while hypertensive diseases (29.4%) were associated with unruptured aneurysms. A significant seasonal variation, highest during autumn and followed by in winter, was observed in the overall ruptured and unruptured AAA deaths. CONCLUSIONS: This study highlights the need to accurately document epidemiologic trends related to AAA in Brazil. We demonstrate the burden of AAA on mortality in older individuals, and our results may assist with effective planning of mortality prevention and control in patients with AAA.

Mortality from diabetes mellitus and its impact on life expectancy at 60 years of age in Mexico / Mortalidad por diabetes mellitus y su impacto en la esperanza de vida a los 60 años en México

ABSTRACT OBJECTIVES To analyze the behavior of mortality from diabetes mellitus (DM) for both sexes in Mexico from 1998 to 2018, and its impact on life expectancy (LE) from 60 to 85 years of age in the three-year periods 1998-2000 and 2016-2018, compared with other causes of death, as well as to determine the loss of years of life expectancy associated with DM in each three-year period. METHODS The current study is observational and descriptive. Age-adjusted rates of mortality from DM were calculated for each sex from 1998 to 2018. Sex-specific life tables were constructed for 1998-2000 and 2016-2018, and both LE between 60 and 85 years, and years of life expectancy lost (YLELL) due to DM and selected causes between both ages were calculated. RESULTS Between 1998 and 2018, the adjusted DM-resulting male mortality rate grew 55% in the population aged 60 and over, while the female mortality rate grew 20%. Between 1998-2000 and 2016-2018, male LE for 60-85 age group decreased 0.22 years, while female LE increased 0.24. In 2016-2018, DM was responsible for 1.30 YLEL among men of 60 to 85 years (19% of the total YLEL), and 1.24 YLEL for women (24% of the total), more than the other causes analyzed. CONCLUSIONS The increase in mortality from DM has substantially contributed both to reduce LE of older adult men, and to slow the increase of LE among women aged 60 years and older so far this century. Thus, preventive policies should be implemented since early ages to reduce the high levels of overweight and obesity in the country and, therefore, the significant population ratio suffering from DM.

RESUMEN OBJETIVOS Analizar el comportamiento de la mortalidad por diabetes mellitus (DM) para ambos sexos en México entre 1998 y 2018 y su impacto sobre la esperanza de vida (EV) entre los 60 y 85 años de edad en los trienios 1998-2000 y 2016-2018 - en comparación con otras causas de muerte -, así como determinar la pérdida de años de esperanza de vida asociados a la DM en cada trienio. MÉTODOS El presente estudio es observacional y descriptivo. Se calcularon tasas de mortalidad por DM ajustadas por edad para cada sexo entre 1998 y 2018. Se construyeron tablas de vida por sexo para 1998-2000 y 2016-2018 y se calculó tanto la EV entre 60 y 85 años, como los años de esperanza de vida perdidos (AEVP) por DM, y causas seleccionadas, entre ambas edades. RESULTADOS Entre 1998 y 2018 la tasa ajustada de mortalidad masculina por DM creció 55% en la población de 60 y más, y la femenina 20%. Entre 1998-2000 y 2016-2018, la EV masculina entre 60 y 85 años se redujo 0,22 años, en tanto la femenina aumentó 0,24. En 2016-2018 la DM fue responsable, para los hombres, de 1,30 AEVP entre 60 y 85 años, (19% del total de AEVP) y para las mujeres 1,24 AEVP (24% del total), más que el resto de causas analizadas. CONCLUSIONES El incremento de la mortalidad por DM ha contribuido de manera sustancial tanto a reducir la EV de los hombres adultos mayores, como a ralentizar el aumento de la EV de las mujeres de 60 años y más en lo que va de siglo. Así, resulta necesario implementar políticas preventivas desde edades tempranas que permitan reducir los altos niveles de sobrepeso y obesidad existentes en el país, y por ende, la notable proporción de población que padece DM.

Cancer mortality in the Capitals and in the interior of Brazil: a four-decade analysis / Mortalidade por câncer nas capitais e no interior do Brasil: uma análise de quatro décadas

ABSTRACT OBJECTIVE: to describe the trend of mortality from general cancer and more frequent types among men and women living in the Capitals and other municipalities of the five macro-regions of Brazil between 1978 and 2017. METHODS: Time series study with mortality data corrected by redistribution of ill-defined causes. Proportional cancer mortality was calculated for Brazil and regions. The annual percentage change in rates for total cancer and specific types in each segment and in the selected unit of analysis was calculated by generalized linear regression with Gaussian binding. RESULTS: the proportion of cancer increased progressively for both sexes from 1978 to 2017. Important differences between the Capitals and the interior of the macro-regions were seen with disaggregated data. The greatest declines occurred for stomach cancer, except in the northern and interior regions of the Northeast, and for the cervix cancer, with a generalized fall, with the exception of the interior of the northern region. Lung cancer decreased among men in the Southeast and South regions and had a generalized increase among women. Breast and prostate cancers tended to decrease in the Southeast and South regions and among residents of the Capitals but showing an increase in the interior of the North and Northeast regions. Colorectal cancer had a general tendency to increase; with stability among men in the Capitals of the South region and among women of the Southeast and Midwest regions and, since 2007, a decrease among women in the South region. CONCLUSIONS: Cancer mortality showed great variation among residents of capitals and the interior of the country's major regions. Clear decrease in mortality was seen for the main types in the Southeast and South regions. The North and Northeast regions have patterns compatible with cancers associated with poverty, while the large increase of the cancers related to sedentary lifestyle stand out.

RESUMO OBJETIVO: Descrever a tendência da mortalidade por câncer geral e tipos mais frequentes entre homens e mulheres residentes nas capitais e demais municípios das cinco macrorregiões do Brasil entre 1978 e 2017. MÉTODOS: Estudo de séries temporais com dados de mortalidade corrigidos por redistribuição das causas maldefinidas. Foi calculada a mortalidade proporcional de câncer para Brasil e regiões. A variação percentual anual das taxas para o total de câncer e tipos específicos em cada segmento e na desagregação selecionada foi calculada por regressão linear generalizada com ligação gaussiana. RESULTADOS: A proporção de câncer aumentou progressivamente para ambos os sexos de 1978 a 2017. Diferenças importantes entre as capitais e o interior das macrorregiões foram vistas com dados desagregados. Os maiores declínios ocorreram para o câncer de estômago, exceto nas regiões Norte e interior da Nordeste, e de colo do útero, com queda generalizada, com exceção do interior da região Norte. O câncer de pulmão teve queda entre homens nas regiões Sudeste e Sul e aumento generalizado entre mulheres. Os cânceres de mama e de próstata tenderam a diminuir nas regiões Sudeste e Sul e entre residentes das capitais, mostrando, porém, aumento no interior das regiões Norte e Nordeste. O câncer colorretal teve tendência geral de aumento; nas capitais houve estabilidade entre homens da região Sul e entre mulheres das regiões Sudeste e Centro-Oeste e queda entre mulheres da região Sul a partir de 2007. CONCLUSÕES: A mortalidade por câncer apresentou grande variação entre os residentes de capitais e do interior das grandes regiões do país. Diminuição clara da mortalidade foi vista para os principais tipos nas regiões Sudeste e Sul. As regiões Norte e Nordeste apresentam padrões compatíveis com cânceres associados à pobreza ao mesmo tempo que se destacam pelo grande aumento daqueles relacionados ao estilo de vida sedentário.

Mortality trend due to Hepatitis B and C in the city of São Paulo, 2002-2016 / Tendência de mortalidade por hepatites B e C no município de São Paulo, 2002-2016

ABSTRACT OBJECTIVE: To describe mortality due to hepatitis B and C as underlying cause in the municipality of São Paulo, verifying the trend of these rates, and to assess the association of these diseases with others, from 2002 to 2016. METHODS: This is a time series study on mortality due to hepatitis B and C according to sex, with data from the Sistema de Informação de Mortalidade (SIM - Mortality Information Sistem). Prais Winsten regression was used in rate trend analysis. RESULTS: The findings of this study showed a trend of decline of mortality from hepatitis B and C in recent years, particularly among males. These infections were important associated causes of liver cell carcinoma and HIV. The proportion of deaths under 70 years of age stands out. CONCLUSIONS: The study provides a baseline for research on mortality trend and the impact of interventions, given the history of expanded detection and supply of treatments, including the most recent antivirals in Brazil, since 2015.

RESUMO OBJETIVO: Descrever a mortalidade por hepatites B e C como causa básica no município de São Paulo, verificando a tendência dessas taxas, e avaliar a associação dessas doenças a outras no período de 2002 a 2016. MÉTODOS: Trata-se de um estudo de série temporal sobre mortalidade por hepatites B e C segundo sexo, com dados do Sistema de Informação de Mortalidade. A regressão de Prais Winsten foi usada na análise de tendência das taxas. RESULTADOS: Os achados do presente estudo mostraram tendência de declínio da mortalidade por hepatites B e C nos últimos anos, particularmente entre pessoas do sexo masculino. Essas infecções foram causas associadas importantes ao carcinoma de células hepáticas e ao HIV. Destaca-se a proporção de óbitos com menos de 70 anos de idade. CONCLUSÕES: O estudo fornece uma linha de base para pesquisas de tendência de mortalidade e de impacto de intervenções, visto o histórico de ampliação da detecção e oferta de tratamentos, incluindo os mais recentes antivirais no Brasil, desde 2015.

Trends in prostate cancer mortality in the state of São Paulo, 2000 to 2015 / Tendências na mortalidade por câncer de próstata no estado de São Paulo, 2000 a 2015

ABSTRACT OBJECTIVE To estimate the magnitude and identify patterns of change in prostate cancer mortality in the state of São Paulo and in the 17 regional health care networks, according to age groups from 50 years onwards, in the period between 2000 to 2015. METHODS Age-adjusted mortality rates (per 100,000 men) were calculated by the direct method using the Segi world population as standard. Joinpoint regression was used to calculate the average annual percent change (AAPC), with a confidence interval of 95% (95%CI), by regional network and age group (50-59, 60-69, 70-79 and 80 years or more). RESULTS For the state of São Paulo, age-adjusted mortality rates were 15.2, 13.3 and 11.9 per 100,000 men, respectively, in the periods between 2000 to 2005, 2006 to 2010 and 2011 to 2015, with a significant decrease trend (AAPC = -2.10%; 95%CI -2.42 - -1.79) each year. Among the 17 networks, 11 presented significant mean annual reductions, ranging from -1.72% to -3.05%. From the age of 50 onwards, there was a sharper reduction in the groups from 50 to 59 (AAPC = -2.33%; 95%CI -3.04 - -1.62) and 60 to 69 years (AAPC = -2.84%; 95%CI - 3.25 - -2.43). CONCLUSION Although reductions in mortality are still slight, they indicate progress in prostate cancer control actions. Screening actions and changes in therapeutic behaviors in recent decades may be modifying incidence and survival, resulting in changes in the mortality profile. More detailed studies will be useful in understanding the factors that lead to the interregional variations found.

RESUMO OBJETIVO Estimar a magnitude e identificar padrões de mudança na mortalidade por câncer de próstata no estado de São Paulo e nas 17 redes regionais de atenção à saúde, segundo grupos etários a partir dos 50 anos, no período de 2000 a 2015. MÉTODOS As taxas de mortalidade ajustadas por idade (por 100 mil homens) foram calculadas pelo método direto usando a população mundial de Segi como padrão. A análise de regressão Joinpoint foi utilizada para calcular as variações percentuais anuais médias (AAPC), com intervalo de confiança de 95% (IC95%), por rede regional e grupo etário (50-59, 60-69, 70-79 e 80 anos ou mais). RESULTADOS Para o estado de São Paulo, as taxas ajustadas de mortalidade foram de 15,2, 13,3 e 11,9/100 mil homens, respectivamente, nos períodos de 2000 a 2005, 2006 a 2010 e 2011 a 2015, com tendência de decréscimo significativo (AAPC = -2,10%; IC95% -2,42 - -1,79) a cada ano. Das 17 redes, 11 apresentaram reduções médias anuais significativas, que variaram entre -1,72% e -3,05%. A partir dos 50 anos, verificou-se redução mais acentuada nos grupos de 50 a 59 (AAPC = -2,33%; IC95% -3,04 - -1,62) e 60 a 69 anos (AAPC = -2,84%; IC95% -3,25 - -2,43). CONCLUSÕES Embora as reduções na mortalidade ainda sejam discretas, indicam progresso nas ações de controle do câncer de próstata. Ações de rastreamento e mudanças nas condutas terapêuticas nas últimas décadas podem estar modificando a incidência e a sobrevida, resultando em mudanças no perfil de mortalidade. Estudos mais detalhados serão úteis na compreensão dos fatores que levam às variações inter-regionais encontradas.

Mortality from gastroschisis in the state of Rio de Janeiro: a 10-year series / Mortalidade por gastrosquise no estado do Rio de Janeiro: uma série de 10 anos

ABSTRACT OBJECTIVE To analyze mortality and associated factors in a series of gastroschisis at birth in the state of Rio de Janeiro in a 10-year period (2005 to 2014). METHOD A retrospective cohort study, which related the databases of the Live Births Information System and the Mortality Information System by probabilistic linkage. Final database was constructed in two stages: preparation of the two initial databases and establishment of relationships between them. RESULTS Preterm newborns and those with low birthweight had higher risk of death, with statistical significance (p = 0.03 and p = 0.006, respectively). Regarding place of birth, although death frequency was higher in maternity units than in general hospitals (p = 0.04; OR = 0.5; 95%CI 0.3-1.0), it was observed that a unit characterized as a general hospital had a high birth frequency (61.2%). Furthermore, the comparative analysis of the risk of death between this unit and others showed a 7.5 higher risk of death in general hospitals and 3.2 higher in maternity units, with statistical significance (p < 0.001). Moreover, births in level II intensive care units had 3.9 times more risk of death compared with level III (p < 0.001). CONCLUSION This study foments the discussion of two possible strategies in the treatment of gastroschisis in newborns. First, the centralization of care in tertiary units, enabling malformation care to be analyzed in a more detailed and standardized manner. Second, and perhaps more feasible, the elaboration of clinical guidelines to standardize immediate care for gastroschisis in babies born outside tertiary centers, as well as the standardization of their transportation until arrival at the tertiary center.

RESUMO OBJETIVO Analisar a mortalidade e fatores associados em uma série de nascimentos com gastrosquise no estado do Rio de Janeiro em 10 anos (2005 a 2014). MÉTODO Estudo de coorte retrospectiva, no qual foram relacionadas as bases de dados do Sistema de Informação sobre Nascidos Vivos e do Sistema de Informação sobre Mortalidade por linkage probabilístico. A base de dados final foi construída em duas etapas, que consistiram em: preparo das duas bases de dados iniciais e estabelecimento de relações entre elas. RESULTADOS Os recém-nascidos pré-termo e os com baixo peso ao nascer tiveram maior chance de óbito, com significância estatística (p = 0,03 e p = 0,006, respectivamente). Em relação ao local de nascimento, embora a frequência de óbito tenha sido maior nas maternidades do que em hospitais gerais (p = 0,04; OR = 0,5; IC95% 0,3-1,0), foi observado que uma unidade caracterizada como hospital geral apresentou uma frequência alta de nascimentos (61,2%) e, na análise comparativa da chance de óbito dessa unidade com as demais, encontrou-se uma chance de morrer 7,5 maior em hospitais gerais e 3,2 maior em maternidades, com significância estatística (p < 0,001). Além disso, nascer em unidades de terapia intensiva tipo II aumentou a chance de óbito em 3,9 vezes em comparação com as do tipo III (p < 0,001). CONCLUSÃO Este estudo dá subsídios para a discussão de duas possíveis estratégias no tratamento de recém-nascidos com gastrosquise. A primeira seria a centralização do cuidado em unidades terciárias, possibilitando que o cuidado à malformação seja analisado de forma mais minuciosa e padronizada. A segunda, e talvez mais factível, seria a elaboração de diretrizes clínicas que padronizem o cuidado imediato aos bebês com gastrosquise nascidos fora de centros terciários, bem como a padronização do transporte deles até a chegada ao centro terciário.

Fetal mortality and the challenges for women's health care in Brazil / Mortalidade fetal e os desafios para a atenção à saúde da mulher no Brasil

ABSTRACT OBJECTIVE: To establish a historical series of fetal mortality in Brazil and regions between 1996 and 2015, identifying its behavior and trend. METHODS: A descriptive study on cases of fetal deaths in Brazil and in each region reported from 1996 to 2015, registered in DATASUS and classified by ICD-10. Maternal age and schooling, duration of gestation and type of delivery were considered. We calculated the fetal mortality rate between 1996 and 2015 to build historical series. RESULTS: The time series shows a steady chart of the fetal mortality rate (FMR) from 2000 in Brazil and in all regions. The country's fetal mortality rate rose from 8.19 in 1996 to 9.50 per 1,000 births in 2015. There was an increasing trend in fetal deaths whose root cause appears in chapter XVII of ICD-10 in Brazil and in all regions. Deaths from Chapter XVI causes showed a trend of increase only in the Northeast region, while other basic causes showed a trend of increase in the Southeast and South regions. In the Brazilian scope, there was an increasing trend of fetal deaths in mothers in the 10-14 and 25-44 years age groups. In Brazil and in all regions, there was an increase of the FMR in women with more than 8 years of schooling. Fetal deaths predominated between 28 and 36 weeks of gestation, with a growing trend in Brazil and all regions, except in the South (steady). Vaginal delivery prevailed, with a steady trend, while cesarean sections showed an increasing trend in Brazil and in all regions. CONCLUSIONS: The quality of information about fetal deaths, investments in research committees, and improvement in the quality of prenatal care should be prioritized to enable more effective coping and to reduce the fetal mortality rate in Brazil.

RESUMO OBJETIVO: Traçar uma série histórica da mortalidade fetal no Brasil e regiões entre 1996 e 2015, identificando seu comportamento e tendência. MÉTODOS: Estudo descritivo sobre casos de óbitos fetais no Brasil e em cada região notificados de 1996 a 2015, registrados no Datasus e classificados pela CID-10. A idade e escolaridade da mãe, duração da gestação e tipo de parto foram considerados. Foi realizado o cálculo da taxa de mortalidade fetal entre 1996 e 2015 para construção das séries históricas. RESULTADOS: A série temporal apresenta um quadro estacionário na taxa de mortalidade fetal a partir de 2000 no Brasil e em todas as regiões. A taxa de mortalidade fetal do país passou de 8,19 em 1996 para 9,50 por 1.000 nascimentos em 2015. Houve tendência crescente dos óbitos fetais cuja causa básica consta no capítulo XVII da CID-10 no Brasil e em todas as regiões. Óbitos por causas do capítulo XVI apresentaram tendência de aumento somente na região Nordeste, enquanto outras causas básicas mostraram tendência de aumento nas regiões Sudeste e Sul. No âmbito brasileiro, houve tendência crescente de óbitos fetais em mães nas faixas etárias de 10-14 anos e 25-44 anos. No Brasil e em todas as regiões, houve aumento nas mulheres com mais de oito anos de escolaridade. Os óbitos fetais predominaram entre a 28ª e a 36ª semana de gestação, com tendência crescente no Brasil e todas as regiões, exceto no Sul (estacionário). O tipo de parto predominante foi vaginal, com tendência estacionária, enquanto as cesarianas apresentaram tendência crescente no Brasil e em todas as regiões. CONCLUSÕES: A qualidade da informação sobre os óbitos fetais, investimentos nos comitês de investigação e melhora na qualidade do pré-natal devem ser priorizados para possibilitar um enfrentamento mais efetivo e diminuir a taxa de mortalidade fetal no Brasil.

Trends in tuberculosis mortality in Brazil (1990-2015): joinpoint analysis / Tendência da mortalidade por tuberculose no Brasil (1990-2015): análise por pontos de inflexão

ABSTRACT The objective of this study was to analyze trends in the tuberculosis mortality rate in Brazil (1990-2015) in an ecological time-series analysis. The indicators were obtained from the Brazilian National Ministry of Health. A joinpoint regression model was applied for the temporal analysis, with a level of significance of 5%. During the period in question, there was a trend toward a reduction in mortality in the country as a whole (p < 0.001) and in each of its five regions. The states with the highest tuberculosis mortality rates were Rio de Janeiro (7.0/100,000 population) and Pernambuco (5.0/100,000 population). Eleven states and the Federal District of Brasília showed downward trends. Only the state of Alagoas showed a significant increase (p < 0.001). The temporal behavior observed indicates that tuberculosis continues to be a major public health problem in Brazil.

RESUMO Objetivou-se analisar a tendência da taxa de mortalidade por tuberculose no Brasil (1990-2015) em um estudo ecológico de séries temporais. Os indicadores foram obtidos do Ministério da Saúde. Aplicou-se o modelo por pontos de inflexão para a análise temporal. Houve uma tendência significativa de redução da mortalidade no Brasil (p < 0,001) e em suas cinco regiões no período estudado. Os estados com as maiores taxas foram Rio de Janeiro (7,0/100.000 habitantes) e Pernambuco (5,0/100.000 habitantes). Onze estados e o Distrito Federal apresentaram tendência de redução da taxa. Somente Alagoas mostrou um crescimento significativo (p < 0,001). O comportamento temporal verificado indica que a tuberculose ainda figura como um importante problema de saúde pública no país.

Desaceleración en la reducción de la mortalidad materna en Chile impide alcanzar el 5° Objetivo de Desarrollo del Milenio / Slowdown in reducing maternal mortality in Chile prevents reach the 5th Millennium Development Goal

Antecedentes: en Chile, a pesar de la importante reducción de la mortalidad materna en la década de los 90, los avances distan de los objetivos comprometidos. Objetivos: analizar la tendencia de la razón de mortalidad materna (RMM) en Chile desde 1990 al 2015 y de factores epidemiológicos que afectan el cumplimiento del 5° Objetivo del Mileno (5°OM). Métodos: estudio observacional a nivel nacional. Analizamos la tendencia del cambio porcentual anual promedio (CPAP) y puntos de inflexión de la RMM junto con la evolución de los nacimientos, muertes maternas y sus causas. Además, analizamos los nacimientos por edad y la distribución de la razón de mortalidad materna por edad y por causa de muerte materna. Resultados: en Chile la RMM se redujo un 61% entre 1990 y 2015, con una inflexión desde el 2001 (IC 95% 1997 a 2004) demostrando dos periodos: 1990-2001 (CPAP -6,97%; IC 95% -8,63 a -5,29) y 2001-2015 (CPAP -0,66%; IC 95% -2,40 a 1,10). En el segundo período la tasa de natalidad disminuyó con menor pendiente, los nacimientos de madres de 15-29 años disminuyeron, mientras que en los otros estratos de edad los nacimientos aumentaron. En ambos períodos las primeras causas de muerte fueron hipertensión arterial, enfermedades concurrentes y aborto. En el segundo período la muerte materna por hipertensión arterial y aborto se redujo, mientras que por enfermedades concurrentes aumentó. Conclusiones: en Chile la RMM es estacionaria desde el 2001 y se asocia a cambios en la distribución en la edad materna y causas de muerte. (AU)

Background: in Chile, despite the significant reduction in maternal mortality in the 1990s, the advances are far from the committed objectives. Aim: To analyze trends of the maternal mortality ratio (MMR) in Chile from 1990 to 2015 and epidemiologic factors that threaten the5th Millennium Goal. Methods: an observational study at the country level. We performed a trend analysis of the average annual percent change (AAPC) and models for joint point analyses for MMR, births, maternal deaths and their causes. In addition, we assessed the Odds Ratios for births by maternal age and the distribution of the maternal mortality rate by maternal age and main death causes. Results: in Chile, a reduction of 61% in MMR was observed from 1990 to 2015 with a trend join point in 2001 (CI 95% 1997 to 2004) indicating two periods: 1990-2001 (AAPC -6.97%; 95% CI -8.63 to -5.29) and 2001-2015 (AAPC - 0.66%; 95% CI -2.4 to 1.10). In the second period the birth rate decreased with a lower slope, the births of mothers in the age group 15-29 decreased, while in the other age groups the births increased. In both periods, main maternal death causes were hypertension, concurrent illness, and abortion. In the second period, maternal deaths associated to hypertension and abortion decreased, whereas deaths associated to concurrent illness increased. Conclusions: in Chile, MMR has been stationary since 2001 and is associated with changes in the distribution of maternal age and causes of death.(AU)

Infant mortality trend in the city of Rio Branco, AC, 1999 to 2015 / Tendência da mortalidade infantil no município de Rio Branco, AC, 1999 a 2015

ABSTRACT OBJECTIVE Analyze the trend of infant mortality in Rio Branco, state of Acre, from 1999 to 2015. METHODS An ecological observational study of a time series, in which data from deaths from the Information System on Mortality and Births of the Information System on Live Births were used. The annual percentage change was estimated using the Joinpoint software. RESULTS The infant mortality rate decreased from 26.99 in 1999 to 14.50 in 2015 per 1,000 live births, with an annual percentage change of -4.37 (95%CI -5.4- -3.4). When stratified by age components, the neonatal period presented an annual percentage change of -4.73 (95%CI -5.7- -3.7), and the post-neonatal period was -3.7 (95%CI -5.4- -2.0). Avoidability, avoidable causes and poorly defined causes showed a downward trend throughout the period and causes not clearly preventable showed an upward trend until 2008. The group of causes that contributed most to the infant deaths during the period studied was perinatal diseases, followed by malformations, infectious and parasitic diseases, and respiratory diseases. CONCLUSIONS Despite the decreasing trend in infant mortality rates in the capital compared to developed countries, it is relatively high.

RESUMO OBJETIVO Analisar a tendência da mortalidade infantil em Rio Branco, AC, de 1999 a 2015. MÉTODOS Estudo observacional ecológico de série temporal, em que foram utilizados dados de óbitos do Sistema de Informações sobre Mortalidade e Nascimentos do Sistema de Informações sobre Nascidos Vivos. Estimou-se a variação percentual anual por meio do software Joinpoint. RESULTADOS A taxa de mortalidade infantil reduziu de 26,99, em 1999, para 14,50, em 2015, por 1.000 nascidos vivos, com variação percentual anual de -4,37 (IC95% -5,4- -3,4). Quando estratificada por componentes etários, o neonatal apresentou variação percentual anual de -4,73 (IC95% -5,7- -3,7), e o pós-neonatal de -3,7 (IC95% -5,4- -2,0). A evitabilidade, as causas evitáveis e as causas mal definidas apresentaram tendência descendente em todo o período e as causas não claramente evitáveis apresentaram tendência ascendente até 2008. O grupo de causas que mais contribuiu para os óbitos infantis no período estudado foi o das afecções perinatais, seguido pelo das malformações, das doenças infecciosas e parasitárias, e do grupo das doenças respiratórias. CONCLUSÕES Apesar da tendência decrescente da taxa de mortalidade infantil na capital, quando comparada à de países desenvolvidos, mostra-se relativamente elevada.

Trend of oral and pharyngeal cancer mortality in Brazil in the period of 2002 to 2013 / Tendência de mortalidade por câncer de boca e faringe no Brasil no período 2002-2013

ABSTRACT OBJECTIVE To analyze the trend of oral and pharyngeal cancer mortality rates in the period of 2002 to 2013 in Brazil according to sex, anatomical site, and macroregion of the country. METHODS The mortality data were obtained from the Mortality Information System and the population data were obtained from the Brazilian Institute of Geography and Statistics. The trend of the rates standardized by sex and age was calculated using the Prais-Winsten estimation, and we obtained the annual percentage change and the respective 95% confidence intervals, analyzed according to sex, macroregion, and anatomical site. RESULTS The average coefficient of oral cancer mortality was 1.87 per 100,000 inhabitants and it remained stable during the study period. The coefficient of pharyngeal cancer mortality was 2.04 per 100,000 inhabitants and it presented an annual percentage change of -2.6%. Approximately eight in every 10 deaths occurred among men. There was an increase in the rates of oral cancer in the Northeast region (annual percentage change of 6.9%) and a decrease in the Southeast region (annual percentage change of -2.9%). Pharyngeal cancer mortality decreased in the Southeast and South regions with annual percentage change of -4.8% and -5.1% respectively. Cancer mortality for tonsil, other major salivary glands, hypopharynx, and other and unspecified parts of mouth and pharynx showed a decreasing trend while the other sites presented stability. CONCLUSIONS Pharyngeal cancer mortality decreased in the period of 2002 to 2013. Oral cancer increased only in the Northeast region. Mortality for tonsil cancer, other major salivary glands, hypopharynx, and other and ill-defined sites in the lip, oral cavity, and pharynx decreased.

RESUMO OBJETIVO Analisar a tendência das taxas de mortalidade por câncer de boca e de faringe no período de 2002-2013 no Brasil segundo sexo, sítio anatômico e macrorregião do país. MÉTODOS Os dados sobre mortalidade foram obtidos junto ao Sistema de Informações sobre Mortalidade e os dados das populações foram obtidos junto ao Instituto Brasileiro de Geografia e Estatística. A tendência das taxas padronizadas por sexo e faixa etária foi calculada por regressão de Prais-Winstein, obtendo a sua variação percentual anual e os respectivos intervalos de confiança de 95%, analisados segundo sexo, macrorregião e sítio anatômico. RESULTADOS O coeficiente médio de mortalidade por câncer de boca foi de 1,87/100.000 habitantes e permaneceu estável durante o período estudado. O coeficiente de mortalidade por câncer de faringe foi de 2,04/100.000 habitantes e apresentou variação percentual anual de -2,6%. Aproximadamente oito em cada 10 óbitos ocorreram entre homens. Observou-se aumento nas taxas por câncer de boca na região Nordeste (variação percentual anual de 6,9%) e diminuição na região Sudeste (variação percentual anual -2,9%). Mortalidade por câncer de faringe diminuiu nas regiões Sudeste e Sul com variação percentual anual de -4,8% e -5,1% respectivamente. Mortalidade por câncer de amígdala, outras glândulas salivares maiores, hipofaringe e outras partes não especificas de boca e faringe, apresentaram tendência de declínio enquanto os demais sítios apresentaram estabilidade. CONCLUSÕES A mortalidade por câncer de faringe apresentou diminuição no período 2002-2013. O câncer de boca apresentou aumento só na região Nordeste. Mortalidade por câncer de amígdala, outras glândulas maiores, hipofaringe e outras localizações mal definidas de lábio, cavidade oral e faringe mostraram declínio.

Maternal education and age: inequalities in neonatal death / Escolaridade e idade materna: desigualdades no óbito neonatal

ABSTRACT OBJECTIVE Evaluate the interaction between maternal age and education level in neonatal mortality, as well as investigate the temporal evolution of neonatal mortality in each stratum formed by the combination of these two risk factors. METHODS A nonconcurrent cohort study, resulting from a probabilistic relationship between the Mortality Information System and the Live Birth Information System. To investigate the risk of neonatal death we performed a logistic regression, with an odds ratio estimate for the combined variable of maternal education and age, as well as the evaluation of additive and multiplicative interaction. The neonatal mortality rate time series, according to maternal education and age, was estimated by the Joinpoint Regression program. RESULTS The neonatal mortality rate in the period was 8.09‰ and it was higher in newborns of mothers with low education levels: 12.7‰ (adolescent mothers) and 12.4‰ (mother 35 years old or older). Low level of education, without the age effect, increased the chance of neonatal death by 25% (OR = 1.25, 95%CI 1.14-1.36). The isolated effect of age on neonatal death was higher for adolescent mothers (OR = 1.39, 95%CI 1.33-1.46) than for mothers aged ≥ 35 years (OR = 1.16, 95%CI 1.09-1.23). In the time-trend analysis, no age group of women with low education levels presented a reduction in the neonatal mortality rate for the period, as opposed to women with intermediate or high levels of education, where the reduction was significant, around 4% annually. CONCLUSIONS Two more vulnerable groups - adolescents with low levels of education and older women with low levels of education - were identified in relation to the risk of neonatal death and inequality in reducing the mortality rate.

RESUMO OBJETIVO Avaliar a interação entre idade e escolaridade materna na mortalidade neonatal, assim como investigar a evolução temporal da mortalidade neonatal em cada estrato formado pela combinação desses dois fatores de risco. MÉTODOS Estudo de coorte não concorrente, resultante de relacionamento probabilístico entre o Sistema de Informações sobre Mortalidade e o Sistema de Informações sobre Nascidos vivos. Para investigar o risco de óbito neonatal, foi realizada regressão logística, com estimativa de odds ratio para variável combinada escolaridade e idade materna, além da avaliação de interação aditiva e multiplicativa. A série temporal da taxa de mortalidade neonatal, de acordo com escolaridade e idade maternas, foi estimada pelo programa Joinpoint regression. RESULTADOS A taxa de mortalidade neonatal no período foi de 8,09‰, sendo mais elevada em recém-nascidos de mães com baixa escolaridade: 12,7‰ (mães adolescentes) e 12,4‰ (mães com 35 anos e mais). A baixa escolaridade, sem efeito da idade, aumentou a chance de óbito neonatal em 25% (OR = 1,25; IC95% 1,14-1,36). Já o efeito isolado da idade no óbito neonatal foi maior para mães adolescentes (OR = 1,39; IC95% 1,33-1,46) do que para mães com idade ≥ 35 anos (OR = 1,16; IC95%1,09-1,23). Na análise temporal, nenhuma faixa etária de mulheres com baixa escolaridade apresentou redução da taxa de mortalidade neonatal no período, em contraponto às mulheres com escolaridade intermediária ou elevada, onde a redução foi significante, em torno de 4% anualmente. CONCLUSÕES Detectaram-se dois grupos mais vulneráveis - adolescentes de baixa escolaridade e mulheres mais velhas de baixa escolaridade - em relação ao risco de óbito neonatal e à desigualdade na redução da taxa de mortalidade.
