Inequalities in infant mortality in Brazil at subnational levels in Brazil, 1990 to 2015

Temporal trends in neonatal mortality in Pernambuco

OBJECTIVE

To verify the temporal trend of neonatal mortality in the health regions of Pernambuco between 2000 and 2020.

METHOD

A time-series ecological study was conducted, analyzing the total neonatal mortality rate and its early and late components. For regression analysis, Joinpoint Regression was applied, trends were classified, and annual and average percentage changes were calculated for the period, with a significance level of 95%.

RESULTS

The average neonatal mortality rate in Pernambuco was 11.5 during the studied period. A decreasing trend in neonatal mortality rate was observed, especially in the early component. The region where the state capital is located showed the fastest decrease across all components.

CONCLUSION

The temporal trend of neonatal mortality was decreasing; however, the rate of reduction was not uniform across the health regions of the state, and the implementation of the Mãe Coruja Pernambucana Program did not impact the trend in neonatal mortality.

Mortality by avoidable causes in Brazil from 1990 to 2019: data from the Global Burden of Disease Study

OBJECTIVES

The aim of this study was to analyse the trends of avoidable mortality in Brazil from 1990 to 2019 and its correlation with sociodemographic indexes (SDIs).

STUDY DESIGN

Epidemiological mortality trends.

METHODS

This study analysed data from the Global Burden of Disease database. The list of causes of avoidable death, as proposed by Nolte and McKee, was applied and included 32 causes. The current study used age-standardised mortality rates and the rates of change, in addition to a correlation analysis between avoidable death and the SDI.

RESULTS

Mortality rates decreased from 343.90/100,000 inhabitants in 1990 to 155.80/100,000 inhabitants in 2019. Infectious diseases showed the largest decline in mortality rates, but notable decreases were also found for diarrhoeal diseases (-94.9%), maternal conditions (-66.5%) and neonatal conditions (-60.5%). Mortality rates for non-communicable diseases (NCDs) also decreased (-48%) but maintained a similar absolute number of deaths in 2019 compared with 1990. Decreased mortality rates were also found for ischaemic heart disease (-49.1%), stroke (-61.4%) and deaths due to adverse effects caused by medical treatments (-26.2%). Avoidable mortality rates declined in all of the 27 Brazilian states, and a high correlation was found between deaths and SDI (R = -0.74; P < 0.000001).

CONCLUSIONS

A reduction in avoidable deaths was found throughout Brazil over the study period, although major regional inequalities were revealed. Richer states presented the best overall reduction in mortality rates. The biggest decreases in mortality were seen in maternal and paediatric infectious diseases in the poorest states due to the expansion of the Primary Health System and improvements in sanitation. Today, NCDs predominate and efforts should be made to formulate public policies for the prevention and control of NCDs.

Infant mortality in the municipality of São Paulo: trend and social inequality (2006-2019)

OBJECTIVE

Considering the published evidence on the impact of recent economic crises and the implementation of fiscal austerity policies in Brazil on various health indicators, this study aims to analyze how the trend and socio-spatial inequality of infant mortality behaved in the municipality of São Paulo from 2006 to 2019.

METHODS

This is an ecological study with a temporal trend analysis that was developed in municipality of São Paulo, using three residence area strata differentiated according to their social vulnerability following the 2010 São Paulo Social Vulnerability Index. Infant mortality rate, as well as neonatal, and post-neonatal mortality rates, were calculated for each social vulnerability stratum, each year in the period, and for the first and last three triennia. Temporal trends were analyzed by the Prais-Winsten regression model and inequality magnitude, by rate ratios.

RESULTS

We found a decline in infant mortality rate and its components from 2006 to 2015, greater in the stratum with low social vulnerability and in the post-neonatal period when compared to the neonatal one. This decline ended in 2015, stagnating in the next period (2016-2019). Our analysis of infant mortality inequality across social vulnerability stratum showed a significant increase from the initial to the final triennia in the analyzed period; rate ratios increased from 1.36 to 1.48 in the high stratum (compared to the low social vulnerability stratum), and from 1.19 to 1.32 between the medium and low social vulnerability strata.

CONCLUSIONS

The observed stagnation of infant mortality rate decline in 2015 and the increase in socio-spatial inequality point to the urgent need to reformulate current public policies to reverse this situation and reduce inequalities in the risk of infant death.

Associations between primary healthcare and infant health outcomes: a cohort analysis of low-income mothers in Rio de Janeiro, Brazil

Background

Expanding primary healthcare to urban poor populations is a priority in many low-and middle-income countries and is essential to achieve universal health coverage (UHC). Between 2008 and 2016 the city of Rio de Janeiro undertook an ambitious programme to rapidly expand primary care to low-income areas through the family health strategy (FHS). Infant health impacts of this roll out are unknown. This study examines associations between maternal FHS utilisation and birth outcomes, neonatal and infant mortality.

Methods

A cohort of 75,339 live births (January 2009-December 2014) to low-income mothers in Rio de Janeiro was linked to primary care, birth, hospital and death records. The relationship between maternal FHS use and infant health outcomes was assessed through logistic regression with inverse probability treatment weighting and regression adjustment. Socioeconomic inequalities in the associations between FHS use and outcomes were explored through interactions. Primary outcomes were neonatal and infant death. Thirteen secondary outcomes were also examined to explore other important health outcomes and potential mechanisms.

Results

A total of 9002 (12.0%) infants were born to mothers in the cohort who used FHS services either before pregnancy or in the first two trimesters. There was a total of 527 neonatal and 893 infant deaths. Maternal FHS usage during the first two trimesters was associated with substantial reductions in neonatal [adjusted odds ratio (aOR): 0.527, 95% confidence interval (95% CI): 0.345; 0.806] and infant mortality (aOR: 0.672, 95% CI: 0.48; 0.924). Infants born to lower-income mothers and those without formal employment had larger reductions in neonatal and infant mortality associated with FHS use. Maternal FHS in the first two trimesters use was also associated with more antenatal care consultations and a lower risk of low birth weight and preterm birth.

Interpretation

Expanding primary care to low-income populations in Rio de Janeiro was associated with improved infant health and health equity benefits.

Neighborhood inequalities and the decline of infant mortality in São Paulo

This paper documents changes in infant mortality (IM) rates in São Paulo, Brazil, between 2003 and 2013 and examines the association among neighborhood characteristics and IM. We investigate the extent to which increased use of health care services and improvements in economic and social conditions are associated with reductions in IM. Using data from the Brazilian Census and the São Paulo Secretaria Municipal da Saúde/SMS, we conducted a longitudinal analysis of panel data in all 96 districts of São Paulo for every year between 2003 and 2013. Our regression model includes district level measures that reflect economic, health care and social determinants of IM. We find that investments in health care have contributed to lower IM rates in the city, but the direct effect of increased spending is most evident for people living in São Paulo's middle- and high-income neighborhoods. Improvements in social conditions were more strongly associated with IM declines than increases in the use of health care among São Paulo's low-income neighborhoods. To reduce health inequalities, policies should target benefits to lower-income neighborhoods. Subsequent research should document the consequences of recent changes in Brazil's economic capacity and commitment to public health spending for population health.

Interprofessional qualification of prenatal care in the context of primary health care

This study aims to describe and analyze an interprofessional educational intervention for the qualification of prenatal care in the context of primary health care.

METHOD

action-research comprising a prenatal care qualification course with 65 primary health care professionals. Collaborative learning activities were conducted in synchronous and asynchronous meetings.

RESULTS

the reflexive thematic analysis of participants' experiences, views and perceptions on the meanings of the intervention revealed three categories: quality of prenatal care: conceptions and meanings; collaborative learning: strategy to overcome linear and isolated care; the need to evolve from acting locally to thinking globally.

CONCLUSION

the analysis of the interprofessional educational intervention for the qualification of prenatal care in the context of primary health care showed that constructivist, participatory and interprofessional approaches are relevant and pertinent to broaden theoretical perceptions and give new meanings to the work process at different settings of the health network.

Physical/functional rehabilitation in Brazil: spatiotemporal analysis of the offer in the Public Healthcare System

Abstract The complex epidemiological profile of Brazil, the aging population and the proportion of individuals with disabilities have led to a substantial increase in the demand for rehabilitation. The spatiotemporal distribution of the offer of physiotherapy, speech therapy and occupational therapy in the Brazilian public healthcare system from 2007 to 2019 was analyzed for the five macro-regions of the country. Data from the National Register of Health Establishments and census estimates from the Brazilian Institute of Geography and Statistics were used. Indicators of the offer of professionals in these fields services and relative changes in the offer were calculated. The spatial distribution of the relative change in the offer was also determined. A regression model with inflection points was adopted for the analysis of the temporal trend. A growing temporal trend was found in the offer of the three professionals in Brazil as a whole and in all regions of the country, but with a slowdown in growth. Differences were observed in the offer among the regions of the country, revealing healthcare inequality that needs to be overcome. The present findings can assist in planning to expand access to rehabilitation services in the country.

Social inequalities in the temporal trend of mortality from sickle cell disease in Brazil, 1996-2019

Contrary to international trends, the mortality rate of sickle cell disease increased in Brazil after the implementation of the neonatal screening program, probably due to improving access to diagnosis. This study aimed to assess differences in the temporal trend of the mortality rate and median age at death from sickle cell disease in Brazil, considering implemented measures to expand diagnosis, and improve health care access in-country and in the international scenario. Time series were extracted from the Brazilian Mortality Information System from 1996 to 2019. Changes in the mortality rate and median age at death were verified via segmented regression models, which were stratified by sex, region of residence, and age. Most deaths occurred in non-white people, young adults, and the Southeast and Northeast population. Sickle cell disease mortality rate increased until 2010 (13.31%; 95%CI: 6.37; 20.70), particularly in individuals aged 30 years or more (12.78%; 95%CI: 2.98; 23.53) and in the Northeast (12.27%; 95%CI: 8.92; 15.72). Most deaths occurred in the second decade of life (3.01 deaths/million), with a 59% increase in the median age of death in Brazil, from 27.6 to 30.3 years, more pronounced in females and the North Region. The observed gain in the survival of sickle cell disease in Brazil is still much lower than in developed countries and presents regional disparities, probably due to the lack of access to health care and recent treatments, such as hydroxyurea, still restricted to hematological referral centers in Brazilian capitals.

Levelling up: Global examples of reducing health inequalities

There are significant inequalities in health by socio-economic status, race/ethnicity, gender, neighbourhood deprivation and other axes of social inequality. Reducing these health inequalities and improving health equity is arguably the 'holy grail' of public health. This article engages with this quest by presenting and analysing historical examples of when sizeable population-level reductions in health inequalities have been achieved. Five global examples are presented ranging from the 1950s to the 2000s: the Nordic social democratic welfare states from the 1950s to the 1970s; the Civil Rights Acts and War on Poverty in 1960s USA; democratisation in Brazil in the 1980s; German reunification in the 1990s; and the English health inequalities strategy in the 2000s. Welfare state expansion, improved health care access, and enhanced political incorporation are identified as three commonly held 'levellers' whereby health inequalities can be reduced - at scale. The article concludes by arguing that 'levelling up' population health through reducing health inequalities requires the long-term enactment of macro-level policies that aggressively target the social determinants of health.

Changes in the Infant Mortality Rate in Twin Towns of Brazil: An Ecological Study

BACKGROUND

The infant mortality rate (IMR) is a proxy of the living and health conditions of a given population, which allows us to assess the risk of death for children under one year. Although there is, in general, a reduction in infant mortality in Brazil little is known about this indicator in the regions and cities located on the international borders of the Brazilian territory and the changes that occurred in the face of the migratory impact of the Americas in the period from 1996 to 2020. The objectives of this study are to assess IMR in Brazilian Twin Cities (municipalities that are located on the border with a large influx of people) and its social determinants over time.

METHODS

This is an ecological study, whose units of analysis were the Brazilian Twin Cities, between 1996 and 2020, based on data on births and deaths in children under one year, available in the public vital information system in Brazil. Data were identified by the city in which the infant death occurred in addition to the mother's primary city of residence. Correlation measurements were performed to test the associations of the IMR means between the independent variables.

RESULTS

The Twin Cities (Bonfim, Tabatinga, Pacaraima, Porto Murtinho, Cáceres, Foz do Iguaçu, Santo Antônio do Sudoeste e Dionísio Cerqueira) had higher numbers of infant deaths per place of occurrence than the number of deaths per place of maternal residence. The Northern Twin Cities exhibited the highest IMRs. Cities in the Midwest region showed variability. In the South region, most cities showed low rates. A positive correlation was identified with the Gini index with r = 0.67 and a negative correlation with the Municipal Human Development Index indicator of r= -0.70.

CONCLUSIONS

The averages of IMRs in the Twin Cities were higher than in their States. In recent years, there has been an upward trend in infant mortality in these cities.

Spatio-temporal analysis of infant mortality in the city of Rio de Janeiro, 2010-2019

OBJECTIVE

To describe the spatio-temporal distribution of infant mortality and its components in the city of Rio de Janeiro, Brazil, in 2010 and 2019.

METHODS

Infant mortality rate and the neonatal and postneonatal components were estimated. The standardized mortality rate was calculated to detect excess child mortality in the planning areas. Poisson regression was performed to estimate the effect of these planning areas on the years 2010 and 2019. Spatial analysis per neighborhoods was performed to identify the spatial autocorrelation rates, using the Moran's Index and local indicator of spatial association (LISA).

RESULTS

The planning areas are very heterogeneous, depending on the history and evolution of occupation. There is an excess of mortality in planning areas with greater social vulnerability. In the Poisson model, it was observed that in all components, the planning area (PA) of residence was statistically significant as well as the year. Moran's index did not show global spatial autocorrelation. However, when applying the LISA method, autocorrelation was observed at the local level and spatial clusters in the municipality of Rio de Janeiro.

CONCLUSIONS

The spatial heterogeneity of the infant mortality rate in Rio de Janeiro suggests that local health policy strategies of each region consist in an efficient measure for reducing this rate.

Análise espaço-temporal da mortalidade infantil no município do Rio de Janeiro, 2010–2019

RESUMO Objetivo: Descrever a distribuição espaçotemporal da mortalidade infantil eseus componentes no município do Rio de Janeiro nos anos de 2010 e 2019. Métodos: Estimamos a taxa de mortalidade infantil e os componentes neonatal e pós-neonatal. Calculamos a taxa de mortalidade padronizada para detectar excesso de mortalidade infantil nas áreas de planejamento e realizamos regressão de Poisson para estimar o efeito dessas áreas nos anos de 2010 e 2019. Efetuamos análise espacial por bairros para detectar autocorrelação espacial das taxas, com uso do índice de Moran e do indicador local de associação espacial (LISA). Resultados: As áreas de planejamento são muito heterogêneas em função da história e da evolução da ocupação. Há excesso de mortalidade nas áreas de planejamento com maior vulnerabilidade social. No modelo de Poisson, observamos que em todos os componentes a área de planejamento de residência teve significância estatística, assim como o ano. O índice de Moran não mostrou autocorrelação espacial global. Contudo, ao aplicarmos o método LISA, observou-se autocorrelação em nível local e aglomerados espaciais no município do Rio de Janeiro. Conclusões: A heterogeneidade espacial da taxa de mortalidade infantil no Rio de Janeiro sugere que estratégias locais de políticas de saúde para cada região são uma medida eficiente para sua redução.

Burden of disease attributable to Risk Factors in Brazil: an analysis of national and subnational estimates from the 2019 Global Burden of Disease study

INTRODUCTION:

Monitoring trends in risk factors (RFs) and the burden of diseases attributable to exposure to RFs is an important measure to identify public health advances and current inadequate efforts. Objective: Analyze the global burden of disease attributable to exposure RFs in Brazil, and its changes from 1990 to 2019, according to the sex and age group.

METHODS:

This study used data from the Global Burden of Disease study. The Summary Exposure Value, which represents weighted prevalence by risk, was used to estimate exposure to RFs. The mortality and DALYs (Disability Adjusted Life Years) measurements were used to estimate the burden of diseases. For comparisons by year and between Brazilian states, age-standardized rates were used.

RESULTS:

Arterial hypertension was the factor responsible for most deaths in both sexes. For DALYs, the most important RF was the high body mass index (BMI) for women and alcohol consumption for men. Smoking had a substantial reduction in the attributable burden of deaths in the period. An important reduction was identified in the exposure to RFs related to socioeconomic development, such as unsafe water, lack of sanitation, and child malnutrition. Metabolic RFs, such as high BMI, hypertension, and alcohol consumption showed an increase in the attributable burden.

CONCLUSIONS:

Our findings point to an increase in metabolic RFs, which are the main RFs for mortality and DALYs. These results can help to consolidate and strengthen public policies that promote healthy lifestyles, thus reducing disease and death.

Food and nutrition actions for the maternal and child population in primary healthcare: comparative analysis of municipalities in the Metropolitan Region of Baixada Santista, São Paulo, Brazil

ABSTRACT Objective Characterize and comparatively analyse the organization of nutritional attention to prenatal care, the puerperium period and breastfeeding, in primary health care, in two municipalities of Baixada Santista, São Paulo, Brazil. Methods This was an exploratory-analytical study of family health units and the mixed basic care units of Cubatão (n=17) and Guarujá (n=14). For this purpose, seven domains of the Nutritional Attention Assessment Instrument in Primary Health Care were used. Descriptive analysis and the Mann-Whitney and Pearson’s chi-square tests were performed. Results In the comparison between the municipalities, the best scores were obtained in Guarujá. Statistically significant differences were found for the following indicators: support for nutritional attention actions: infrastructure and permanent education (<0.001); food and nutritional surveillance (<0.001); nutritional attention focused on prenatal care (<0.001); and nutritional attention focused on postpartum care and breastfeeding (0.012). Nutritional attention actions for mother-infant groups were more frequent in the city of Guarujá, which compared with Cubatão, achieved better scores for the nutritional attention evaluation indicators. Conclusion The municipality of Guarujá had better indicators of infrastructure and permanent education, food and nutrition surveillance, and puerperal and breastfeeding nutritional care. However, weaknesses persist in the organization of nutritional care in the two cities studied, especially regarding the work process.

Health capabilities and the determinants of infant mortality in Brazil, 2004-2015: an innovative methodological framework

BACKGROUND

Despite the implementation of a set of social and health policies, Brazil has experienced a slowdown in the decline of infant mortality, regional disparities and persistent high death levels, raising questions about the determinants of infant mortality after the implementation of these policies. The objective of this article is to propose a methodological approach aiming at identifying the determinants of infant mortality in Brazil after the implementation of those policies.

METHOD

A series of multilevel panel data with fixed effect nested within-clusters were conducted supported by the concept of health capabilities based on data from 26 Brazilian states between 2004 and 2015. The dependent variables were the neonatal, the infant and the under-five mortality rates. The independent variables were the employment rate, per capita income, Bolsa Família Program coverage, the fertility rate, educational attainment, the number of live births by prenatal visits, the number of health professionals per thousand inhabitants, and the access to water supply and sewage services. We also used different time lags of employment rate to identify the impact of employment on the infant mortality rates over time, and household income stratified by minimum wages to analyze their effects on these rates.

RESULTS

The results showed that in addition to variables associated with infant mortality in previous studies, such as Bolsa Família Program, per capita income and fertility rate, other factors affect child mortality. Educational attainment, quality of prenatal care and access to health professionals are also elements impacting infant deaths. The results also identified an association between employment rate and different infant mortality rates, with employment impacting neonatal mortality up to 3 years and that a family income below 2 minimum wages increases the odds of infant deaths.

CONCLUSION

The results proved that the methodology proposed allowed the use of variables based on aggregated data that could hardly be used by other methodologies.
