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…

Gestational weight gain at the national, regional, and income group levels based on 234 national household surveys from 70 low-income and middle-income countries
Gestational weight gain (GWG) estimates enable the identification of populations of women at risk for adverse outcomes. We described GWG distribution in low- and middle-income countries (LMICs). Demographic and Health Surveys and other national surveys were used to calculate the average GWG by regressing the weight of pregnant women (15–49 years) at the time of the interview on their gestational age, adjusting for sociodemographic factors. A mixe…

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 …
Children of more empowered women are less likely to be left without vaccination in low- and middle-income countries
Background: To help provide a global understanding of the role of gender-related barriers to vaccination, we have used a broad measure of women's empowerment and explored its association with the prevalence of zero-dose children aged 12-23 months across many low- and middle-income countries, using data from standardized national household surveys. Methods: We used data from Demographic and Health Surveys (DHS) of 50 countries with information on …
