          Abstract

          RESUMEN: Objetivo: Analizar la tendencia de la mortalidad neonatal en Brasil de 2015 a 2019 y sus causas prevenibles. Métodos: Estudio ecológico de series temporales con datos extraídos del Sistema de Información sobre Mortalidad y del Sistema de Información sobre Nacidos Vivos. Se calcularon las tasas de mortalidad neonatal general y por causas evitables. El análisis de tendencias se realizó mediante regresión de Prais-Winsten. Resultados: La tasa global de mortalidad neonatal se redujo de 8,78 en 2015 a 8,60 en 2019. Se observaron disparidades en las tasas de mortalidad neonatal entre regiones, con tasas más elevadas en las regiones septentrional (10,3/1.000) y nororiental (9,9/1.000). Predominaron las causas prevenibles mediante una atención adecuada al embarazo, el parto y los cuidados del recién nacido, que en conjunto sumaron el 97,8% de las muertes neonatales del periodo. Se observó una tendencia a la disminución de las causas prevenibles gracias a los cuidados adecuados del recién nacido (p < 0,001). Conclusión: Hubo una disminución en la tasa de mortalidad neonatal en Brasil de 2015 a 2019.

          ABSTRACT: Aim: To analyze the trend of neonatal mortality in Brazil from 2015 to 2019 and its preventable causes. Methods: Ecological time-series study with data extracted from the Mortality Information System and Live Births Information System. Neonatal mortality rates were calculated overall and according to preventable causes. Trend analysis was performed by Prais-Winsten regression. Results: The overall neonatal mortality rate reduced from 8.78 in 2015 to 8.60 in 2019. Disparities in neonatal mortality rates were observed among regions, with higher rates in the northern (10.3/1,000) and northeastern (9.9/1,000) regions. The causes preventable by adequate care for pregnancy, delivery and neonatal care prevailed, together totaling 97.8% of neonatal deaths in the period. There was a decreasing trend in preventable causes due to adequate care of the newborn (p < 0.001). Conclusion: There was a decrease in the neonatal mortality rate in Brazil from 2015 to 2019.

          Global, regional, and national causes of under-5 mortality in 2000–15: an updated systematic analysis with implications for the Sustainable Development Goals

          Summary Background Despite remarkable progress in the improvement of child survival between 1990 and 2015, the Millennium Development Goal (MDG) 4 target of a two-thirds reduction of under-5 mortality rate (U5MR) was not achieved globally. In this paper, we updated our annual estimates of child mortality by cause to 2000–15 to reflect on progress toward the MDG 4 and consider implications for the Sustainable Development Goals (SDG) target for child survival. Methods We increased the estimation input data for causes of deaths by 43% among neonates and 23% among 1–59-month-olds, respectively. We used adequate vital registration (VR) data where available, and modelled cause-specific mortality fractions applying multinomial logistic regressions using adequate VR for low U5MR countries and verbal autopsy data for high U5MR countries. We updated the estimation to use Plasmodium falciparum parasite rate in place of malaria index in the modelling of malaria deaths; to use adjusted empirical estimates instead of modelled estimates for China; and to consider the effects of pneumococcal conjugate vaccine and rotavirus vaccine in the estimation. Findings In 2015, among the 5·9 million under-5 deaths, 2·7 million occurred in the neonatal period. The leading under-5 causes were preterm birth complications (1·055 million [95% uncertainty range (UR) 0·935–1·179]), pneumonia (0·921 million [0·812 −1·117]), and intrapartum-related events (0·691 million [0·598 −0·778]). In the two MDG regions with the most under-5 deaths, the leading cause was pneumonia in sub-Saharan Africa and preterm birth complications in southern Asia. Reductions in mortality rates for pneumonia, diarrhoea, neonatal intrapartum-related events, malaria, and measles were responsible for 61% of the total reduction of 35 per 1000 livebirths in U5MR in 2000–15. Stratified by U5MR, pneumonia was the leading cause in countries with very high U5MR. Preterm birth complications and pneumonia were both important in high, medium high, and medium child mortality countries; whereas congenital abnormalities was the most important cause in countries with low and very low U5MR. Interpretation In the SDG era, countries are advised to prioritise child survival policy and programmes based on their child cause-of-death composition. Continued and enhanced efforts to scale up proven life-saving interventions are needed to achieve the SDG child survival target. Funding Bill & Melinda Gates Foundation, WHO.

            National, regional, and global levels and trends in neonatal mortality between 1990 and 2017, with scenario-based projections to 2030: a systematic analysis

            Summary Background Reducing neonatal mortality is an essential part of the third Sustainable Development Goal (SDG), to end preventable child deaths. To achieve this aim will require an understanding of the levels of and trends in neonatal mortality. We therefore aimed to estimate the levels of and trends in neonatal mortality by use of a statistical model that can be used to assess progress in the SDG era. With these estimates of neonatal mortality between 1990 and 2017, we then aimed to assess how different targets for neonatal mortality could affect the burden of neonatal mortality from 2018 to 2030. Methods In this systematic analysis, we used nationally-representative empirical data related to neonatal mortality, including data from vital registration systems, sample registration systems, and household surveys, to estimate country-specific neonatal mortality rates (NMR; the probability of dying during the first 28 days of life) for all countries between 1990 (or the earliest year of available data) and 2017. For our analysis, we used all publicly available data on neonatal mortality from databases compiled annually by the UN Inter-agency Group for Child Mortality Estimation, which were extracted on or before July 31, 2018, for data relating to the period between 1950 and 2017. All nationally representative data were assessed. We used a Bayesian hierarchical penalised B-splines regression model, which allowed for data from different sources to be weighted differently, to account for variable biases and for the uncertainty in NMR to be assessed. The model simultaneously estimated a global association between NMR and under-5 mortality rate and country-specific and time-specific effects, which enabled us to identify countries with an NMR that was higher or lower than expected. Scenario-based projections were made at the county level by use of current levels of and trends in neonatal mortality and historic or annual rates of reduction that would be required to achieve national targets. The main outcome that we assessed was the levels of and trends in neonatal mortality and the global and regional NMRs from 1990 to 2017. Findings Between 1990 and 2017, the global NMR decreased by 51% (90% uncertainty interval [UI] 46–54), from 36·6 deaths per 1000 livebirths (35·5–37·8) in 1990, to 18·0 deaths per 1000 livebirths (17·0–19·9) in 2017. The estimated number of neonatal deaths during the same period decreased from 5·0 million (4·9 million–5·2 million) to 2·5 million (2·4 million–2·8 million). Annual NMRs vary widely across the world, but west and central Africa and south Asia had the highest NMRs in 2017. All regions have reported reductions in NMRs since 1990, and most regions accelerated progress in reducing neonatal mortality in 2000–17 versus 1990–2000. Between 2018 and 2030, we project that 27·8 million children will die in their first month of life if each country maintains its current rate of reduction in NMR. If each country achieves the SDG neonatal mortality target of 12 deaths per 1000 livebirths or fewer by 2030, we project 22·7 million cumulative neonatal deaths by 2030. More than 60 countries need to accelerate their progress to reach the neonatal mortality SDG target by 2030. Interpretation Although substantial progress has been made in reducing neonatal mortality since 1990, increased efforts to improve progress are still needed to achieve the SDG target by 2030. Accelerated improvements are most needed in the regions and countries with high NMR, particularly in sub-Saharan Africa and south Asia.

              Uso da análise de séries temporais em estudos epidemiológicos

              Esse artigo visa introduzir e cativar o interesse sobre a análise de séries temporais em estudos epidemiológicos. São descritos aspectos conceituais desse tipo de análise e sistematizadas indicações metodológicas. Foram definidos os principais conceitos da análise de séries temporais (tendência, variação cíclica e sazonal, associação e variação aleatória), e operacionalizada sua aplicação epidemiológica. Foram apresentados os métodos para avaliação da tendência (porcentagem de modificação anual), baseados em modelos de regressão de Prais-Winsten, e para quantificação da variação sazonal, segundo o modelo de Serfling. Foi, ainda, introduzida a modalidade de análise de regressão segmentada para séries temporais interrompidas, como estratégia de avaliação do efeito de intervenções em saúde.
