Scientific production on health inequalities using the Brazilian Information System on Live Births
The Brazilian Information System on Live Births (SINASC) is widely used by health managers to plan and monitor maternal and child health programs. Scientific research using SINASC data is also essential to identify underexplored topics that warrant further investigation. This study aims to describe the profile of scientific output based on SINASC data and to determine gaps in the literature, with particular attention to studies addressing health …
Exacerbation of antenatal care inequities as coverage recommendations rise in Brazil
Within-country inequalities in antenatal care (ANC) coverage are widely documented. With recent international guidelines recommending eight or more visits, we hypothesized that this increase could reveal wider inequalities in Brazil, consistent with the Inverse Equity Hypothesis, which postulates that new interventions initially widen socioeconomic gaps because privileged groups are the first to adopt them. We assess how the magnitude of inequali…

Maternity in adolescence in Brazil
Adolescent childbearing is a major public health challenge in Brazil, with a fertility rate of 43.6 births per 1,000 girls aged 15-19 years in 2022. This study investigated inequalities in adolescent fertility rates across Brazilian municipalities and regions and explored their association with sociodemographic characteristics, namely municipal deprivation and population size. Data from the Brazilian Information System on Live Births and the 2022…
Timely initiation of antenatal care in adolescent victims of sexual violence
We investigated the timely initiation of antenatal care among Brazilian adolescents to support the national discussion on the gestational age limit for legal abortion. Using data from the Live Births Information System (SINASC) 2020-2022, we correlated the timely antenatal care (first quarter of pregnancy) with the adolescent’s age, region, ethnicity/skin color, and schooling level; 11,607 annual births result from vulnerable rape. The timely ini…
Inicio oportuno de la atención prenatal en adolescentes víctimas de violencia sexual
Investigamos el inicio oportuno de la atención prenatal entre las adolescentes brasileñas para apoyar la discusión nacional sobre el límite de edad gestacional para el aborto legal. Con datos del Sistema de Información sobre Nacidos Vivos (SINASC) 2020-2022, correlacionamos el inicio oportuno del cuidado prenatal (primer trimestre del embarazo) con la edad de la adolescente, la región, la etnia/color de piel y el nivel de escolaridad; 11.607 naci…

Identifying and Characterizing the Poorest Urban Population Using National Household Surveys in 38 Cities in Sub-Saharan Africa
Identifying and classifying poor and rich groups in cities depends on several factors. Using data from available nationally representative surveys from 38 sub-Saharan African countries, we aimed to identify, through different poverty classifications, the best classification in urban and large city contexts. Additionally, we characterized the poor and rich groups in terms of living standards and schooling. We relied on absolute and relative measur…
Time trends in ethnic inequalities in child health and nutrition
Although measures of annual changes in ethnic or language group inequalities in child health were consistently correlated within each outcome, analyses of such inequalities should rely upon multiple measures. Countries showing progress in one child health outcome did not necessarily show improvements in the remaining outcomes. In-depth analyses at country level are needed to understand the drivers of success in reducing ethnic gaps
Recent trends in maternal and child health inequalities in Latin America and the Caribbean
Although LAC countries are well placed in terms of current levels of health indicators compared to most low- and middle-income countries, important inequalities remain, and reversals are being observed in some areas. More targeted efforts and actions are needed in order to leave no one behind. Monitoring progress with an equity lens is essential, but this will require further investment in conducting surveys routinely
Coverage, Trends, and Inequalities of Maternal, Newborn, and Child Health Indicators among the Poor and Non-Poor in the Most Populous Cities from 38 Sub-Saharan African Countries
Rapid urbanization is likely to be associated with suboptimal access to essential health services. This is especially true in cities from sub-Saharan Africa (SSA), where urbanization is outpacing improvements in infrastructure. We assessed the current situation in regard to several markers of maternal, newborn, and child health, including indicators of coverage of health interventions (demand for family planning satisfied with modern methods, at …
Exploring the potential for a new measure of socioeconomic deprivation status to monitor health inequality
The proposed SDS measure adds analytical possibilities to the health inequality monitoring literature, in line with ethically and conceptually well-founded notions of absolute, multidimensional disadvantage. In addition, it allows for breakdown by its dimensions and components, which may facilitate nuanced analyses of health inequality, its correlates, and determinants

Are the poorest poor being left behind? Estimating global inequalities in reproductive, maternal, newborn and child health
Introduction: Wealth-related inequalities in reproductive, maternal, neonatal and child health have been widely studied by dividing the population into quintiles. We present a comprehensive analysis of wealth inequalities for the composite coverage index (CCI) using national health surveys carried out since 2010, using wealth deciles and absolute income estimates as stratification variables, and show how these new approaches expand on traditional…

Measuring Socioeconomic Inequalities With Predicted Absolute Incomes Rather Than Wealth Quintiles
Objectives. To compare the predictive power of synthetic absolute income measures with that of asset-based wealth quintiles in low- and middle-income countries (LMICs) using child stunting as an outcome. Methods. We pooled data from 239 nationally representative household surveys from LMICs and computed absolute incomes in US dollars based on households’ asset rank as well as data on national consumption and inequality levels. We used multivariab…
