Recent trends in maternal and child health inequalities in Latin America and the Caribbean: analysis of repeated national surveys.

BACKGROUND: Although most Latin American and the Caribbean (LAC) countries made important progress in maternal and child health indicators from the 1990s up to 2010, little is known about such progress in the last decade. This study aims at documenting progress for each country as a whole, and to assess how within-country socioeconomic inequalities are evolving over time. METHODS: We identified LAC countries for which a national survey was available between 2011-2015 and a second comparable survey in 2018-2020. These included Argentina, Costa Rica, Cuba, the Dominican Republic, Guyana, Honduras, Peru, and Suriname. The 16 surveys included in the analysis collected nationally representative data on 221,989 women and 152,983 children using multistage sampling. Twelve health-related outcomes were studied, seven of which related to intervention coverage: the composite coverage index, demand for family planning satisfied with modern methods, antenatal care (four or more visits and eight or more visits), skilled attendant at birth, postnatal care for the mother and full immunization coverage. Five additional impact indicators were also investigated: stunting prevalence among under-five children, tobacco use by women, adolescent fertility rate, and under-five and neonatal mortality rates. For each of these indicators, average annual relative change rates were calculated between the baseline and endline national level estimates, and changes in socioeconomic inequalities over time were assessed using the slope index of inequality. RESULTS: Progress over time and the magnitude of inequalities varied according to country and indicator. For countries and indicators where baseline levels were high, as Argentina, Costa Rica and Cuba, progress was slow and inequalities small for most indicators. Countries that still have room for improvements, such as Guyana, Honduras, Peru and Suriname, showed faster progress for some but not all indicators, although also had wider inequalities. Among the countries studied, Peru was the top performer in terms of increasing coverage and reducing inequalities over time, followed by Honduras. Declines in family planning and immunization coverage were observed in some countries, and the widest inequalities were present for adolescent fertility and antenatal care coverage with eight or more visits. CONCLUSIONS: 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.

Trends and inequities in adolescent childbearing in Latin American and Caribbean countries across generations and over time: a population-based study.

BACKGROUND: Latin America and the Caribbean present the second highest adolescent fertility rate in the world, only after sub-Saharan Africa, and have reached the third position globally in the incidence of motherhood in adolescence. We aimed to explore trends and inequities in adolescent childbearing in the region. METHODS: We used nationally representative household surveys from Latin American and Caribbean countries to address trends in early childbearing (proportion of women having their first livebirth before age 18 years) over generations and in adolescent fertility rates (AFRs; livebirths per 1000 women aged 15-19 years) over time. For early childbearing, we analysed the most recent survey conducted since 2010 from 21 countries (2010-20); for AFR, we analysed nine countries with two or more surveys, with the most recent being conducted from 2010 onwards. For both indicators, variance-weighted least-square regression was used to estimate the average absolute changes (AACs) at the national level and by wealth (bottom 40% vs top 60%), urban versus rural residence, and ethnicity. FINDINGS: Among 21 countries studied, we noted a decrease in early childbearing along generations in 13 of them, with declines varying from -0·6 percentage points (95% CI -1·1 to -0·1) in Haiti to -2·7 percentage points (-4·0 to -1·4) in Saint Lucia. We observed increases over generations in Colombia (1·2 percentage points [0·8 to 1·5]) and Mexico (1·3 percentage points [0·5 to 2·0]) and no changes in Bolivia and Honduras. The fastest early childbearing decline occurred among rural women, whereas no clear pattern was observed for wealth groups. Decreasing estimates from oldest to youngest generations were found among Afro-descendants and non-Afro-descendant and non-indigenous groups, but results were mixed for indigenous people. All nine countries with data for AFR presented reductions over time (-0·7 to -6·5 births per 1000 women per year), with the steepest declines observed in Ecuador, Guyana, Guatemala, and the Dominican Republic. In general, adolescents in rural areas and the poorest adolescents had the largest reductions in AFR. If current trends persist, by 2030 most countries will present AFR values ranging between 45 and 89 births per 1000 women, with notable wealth-related inequalities. INTERPRETATION: Our results indicate a reduction in AFR in Latin American and Caribbean countries that was not necessarily accompanied by a decrease in early childbearing overall. Large inequalities both between countries and within countries were observed, with no clear reduction over time. Understanding trends in adolescent childbearing and its determinants is essential for planning and designing programmes to ensure the desired reductions in rates and gaps across population subgroups.

Time trends in ethnic inequalities in child health and nutrition: analysis of 59 low and middle-income countries.

BACKGROUND: Although ethnicity is a key social determinant of health, there are no global analyses aimed at identifying countries that succeeded in reducing ethnic gaps in child health and nutrition. METHODS: We identified 59 low and middle-income countries with at least two surveys since 2010 providing information on ethnicity or language and on three outcomes: under-five mortality, child stunting prevalence and a composite index (CCI) based on coverage with eight maternal and child health interventions. Firstly, we calculated population-weighted and unweighted measures of inequality among ethnic or language groups within each country. These included the mean difference from the overall national mean (absolute inequality), mean ratio relative to the overall mean (relative inequality), and the difference and ratio between the best- and worst-performing ethnic groups. Second, we examined annual changes in these measures in terms of annual absolute and relative changes. Thirdly, we compared trends for each of the three outcome indicators and identified exemplar countries with marked progress in reducing inequalities. RESULTS: For each outcome indicator, annual changes in summary measures tended to show moderate (Pearson correlation coefficients of 0.4 to 0.69) or strong correlations (0.7 or higher) among themselves, and we thus focused on four of the 12 measures: absolute and relative annual changes in mean differences and ratios from the overall national mean. On average, absolute ethnic or language group inequalities tended to decline slightly for the three outcomes, and relative inequality declined for stunting and CCI, but increased for mortality. Correlations for annual trends across the three outcomes were inconsistent, with several countries showing progress in terms of one outcome but not in others. Togo and Uganda showed with the most consistent progress in reducing inequality, whereas the worst performers were Nigeria, Moldova, Kyrgyzstan, Sao Tome and Principe, and Burkina Faso. CONCLUSIONS: 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.

Breastfeeding: crucially important, but increasingly challenged in a market-driven world.

In this Series paper, we examine how mother and baby attributes at the individual level interact with breastfeeding determinants at other levels, how these interactions drive breastfeeding outcomes, and what policies and interventions are necessary to achieve optimal breastfeeding. About one in three neonates in low-income and middle-income countries receive prelacteal feeds, and only one in two neonates are put to the breast within the first hour of life. Prelacteal feeds are strongly associated with delayed initiation of breastfeeding. Self-reported insufficient milk continues to be one of the most common reasons for introducing commercial milk formula (CMF) and stopping breastfeeding. Parents and health professionals frequently misinterpret typical, unsettled baby behaviours as signs of milk insufficiency or inadequacy. In our market-driven world and in violation of the WHO International Code for Marketing of Breast-milk Substitutes, the CMF industry exploits concerns of parents about these behaviours with unfounded product claims and advertising messages. A synthesis of reviews between 2016 and 2021 and country-based case studies indicate that breastfeeding practices at a population level can be improved rapidly through multilevel and multicomponent interventions across the socioecological model and settings. Breastfeeding is not the sole responsibility of women and requires collective societal approaches that take gender inequities into consideration.

Inequalities in the health, nutrition, and wellbeing of Afrodescendant women and children: A cross-sectional analysis of ten Latin American and Caribbean countries.

Background: Afrodescendants are systematically affected by discrimination in the Americas and few multi-country studies addressed ethnic inequalities in health and wellbeing in the region. We aimed to investigate gaps in coverage of key health outcomes and socioeconomic inequalities between Afrodescendants and non-Afrodescendants populations in Latin American and Caribbean countries. Methods: Using national household surveys (2011-2019) from ten countries, we analyzed absolute inequalities between Afrodescendants and a comparison group that includes non-Afrodescendants and non-Indigenous individuals (henceforth non-Afrodescendants) across 17 indicators in the continuum of reproductive, maternal, newborn, child, and adolescent health. These include indicators of family planning, antenatal care, delivery assistance, child nutrition, immunization coverage, child protection, access to improved water, sanitation and hygiene, adolescent fertility, and early childhood mortality. Inequalities between country-specific subgroups of Afrodescendants were also explored. The slope index of inequality was used to assess wealth-based inequalities within each ethnic group. Findings: Afrodescendants represented from 2·8% (Honduras) to 59·1% (Brazil) of the national samples. Of the 128 combinations of country and indicators with data, Afrodescendants fared worse in 78 (of which 33 were significant) and performed better in 50 (15 significant). More systematic disadvantages for Afrodescendants were found for demand for family planning satisfied, early marriage, and household handwashing and sanitation facilities. In contrast, Afrodescendants tended to present lower c-section rates and lower stunting prevalence. Honduras was the only country where Afrodescendants performed better than non-Afrodescendants in several indicators. Wealth gaps among Afrodescendants were wider than those observed for non-Afrodescendants for most indicators and across all countries. Interpretation: Gaps in health outcomes between Afrodescendants and non-Afrodescendants were observed in most countries, with more frequent disadvantages for the former although, in many cases, the gaps were reversed. Wealth inequalities within Afrodescendants tended to be wider than for non-Afrodescendants. Funding: Pan American Health Organization, Bill and Melinda Gates Foundation, and the Wellcome Trust.

Religious affiliation as a driver of immunization coverage: Analyses of zero-dose vaccine prevalence in 66 low- and middle-income countries.

Background: The literature on the association between religion and immunization coverage is scant, mostly consisting of single-country studies. Analyses in low and middle-income countries (LMICs) to assess whether the proportions of zero-dose children vary according to religion remains necessary to better understand non-socioeconomic immunization barriers and to inform interventions that target zero-dose children. Methods: We included 66 LMICs with standardized national surveys carried out since 2010, with information on religion and vaccination. The proportion of children who failed to receive any doses of a diphtheria-pertussis-tetanus (DPT) containing vaccine - a proxy for no access to routine vaccination or "zero-dose" status - was the outcome. Differences among religious groups were assessed using a test for heterogeneity. Additional analyses were performed controlling for the fixed effect of country, household wealth, maternal education, and urban-rural residence to assess associations between religion and immunization. Findings: In 27 countries there was significant heterogeneity in no-DPT prevalence according to religion. Pooled analyses adjusted for wealth, maternal education, and area of residence showed that Muslim children had 76% higher no-DPT prevalence than Christian children. Children from the majority religion in each country tended to have lower no-DPT prevalence than the rest of the population except in Muslim-majority countries. Interpretation: Analyses of gaps in coverage according to religion are relevant to renewing efforts to reach groups that are being left behind, with an important role in the reduction of zero-dose children.

Birth registration coverage according to the sex of the head of household: an analysis of national surveys from 93 low- and middle-income countries.

BACKGROUND: Within-country inequalities in birth registration coverage (BRC) have been documented according to wealth, place of residence and other household characteristics. We investigated whether sex of the head of household was associated with BRC. METHODS: Using data from nationally-representative surveys (Demographic and Health Survey or Multiple Indicator Cluster Survey) from 93 low and middle-income countries (LMICs) carried out in 2010 or later, we developed a typology including three main types of households: male-headed (MHH) and female-led with or without an adult male resident. Using Poisson regression, we compared BRC for children aged less than 12 months living the three types of households within each country, and then pooled results for all countries. Analyses were also adjusted for household wealth quintiles, maternal education and urban-rural residence. RESULTS: BRC ranged from 2.2% Ethiopia to 100% in Thailand (median 79%) while the proportion of MHH ranged from 52.1% in Ukraine to 98.3% in Afghanistan (median 72.9%). In most countries the proportion of poor families was highest in FHH (no male) and lowest in FHH (any male), with MHH occupying an intermediate position. Of the 93 countries, in the adjusted analyses, FHH (no male) had significantly higher BRC than MHH in 13 countries, while in eight countries the opposite trend was observed. The pooled analyses showed t BRC ratios of 1.01 (95% CI: 1.00; 1.01) for FHH (any male) relative to MHH, and also 1.01 (95% CI: 1.00; 1.01) for FHH (no male) relative to MHH. These analyses also showed a high degree of heterogeneity among countries. CONCLUSION: Sex of the head of household was not consistently associated with BRC in the pooled analyses but noteworthy differences in different directions were found in specific countries. Formal and informal benefits to FHH (no male), as well as women's ability to allocate household resources to their children in FHH, may explain why this vulnerable group has managed to offset a potential disadvantage to their children.

Exposure of Zero-Dose Children to Multiple Deprivation: Analyses of Data from 80 Low- and Middle-Income Countries.

The concept of multiple deprivation recognizes that the same individuals, households, and communities are often exposed to several forms of scarcity. We assessed whether lack of immunization is also associated with nutritional, environmental, and educational outcomes. We analyzed data from nationally representative surveys from 80 low- and middle-income countries with information on no-DPT (children aged 12-23 months without any doses of a diphtheria, pertussis and tetanus containing vaccine), stunting, wasting, maternal education and use of contraception, improved water and sanitation, and long-lasting insecticidal nets. Analyses of how these characteristics overlap were performed at individual and ecological levels. Principal component analyses (PCA) provided additional information on indicator clustering. In virtually all analyses, no-DPT children were significantly more likely to be exposed to the other markers for deprivation. The strongest, most consistent associations were found with maternal education, water, and sanitation, while the weakest associations were found for wasting and bed nets. No-DPT prevalence reached 46.1% in the most deprived quintile from first PCA component derived from deprivation indicators. All children were immunized in the two least deprived quintiles of the component. Our analyses provide strong support for the hypothesis that unimmunized children are also affected by other forms of deprivation.

[SDG3-related inequalities in women's, children's and adolescents' health: an SDG monitoring baseline for Latin America and the Caribbean using national cross-sectional surveysDesigualdades relacionadas ao ODS 3 na saúde da mulher, da criança e do adolescente: linha de base para o monitoramento do ODS na América Latina e no Caribe por meio de pesquisas transversais nacionais]. / Desigualdades relacionadas con el ODS 3 en la salud de las mujeres, los niños y los adolescentes: línea de base para el monitoreo de los ODS en América Latina y el Caribe por medio de encuestas transversales nacionales.

Objectives: Latin America and the Caribbean (LAC) countries have made important progress towards achieving the Sustainable Development Goal (SDG) targets related to health (SDG3) at the national level. However, vast within-country health inequalities remain. We present a baseline of health inequalities in the region, against which progress towards the SDGs can be monitored. Setting: We studied 21 countries in LAC using data from Demographic and Health Surveys and Multiple Indicator Cluster Survey carried out from 2011 to 2016. Participants: The surveys collect nationally representative data on women and children using multistage sampling. In total, 288 207 women and 195 092 children made part of the surveys in the 21 countries. Outcome measures: Five health intervention indicators were studied, related to reproductive and maternal health, along with adolescent fertility and neonatal and under-five mortality rates. Inequalities in these indicators were assessed through absolute and relative measures. Results: In most countries, subnational geographical health gradients were observed for nearly all women, child, and adolescent (WCA) indicators. Coverage of key interventions was higher in urban areas and among the richest, compared with rural areas and poorer quintiles. Analyses by woman's age showed that coverage was lower in adolescent girls than older women for family planning indicators. Pro-urban and pro-rich inequalities were also seen for mortality in most countries. Conclusions: Regional averages hide important health inequalities between countries, but national estimates hide still greater inequalities between subgroups of women, children and adolescents. To achieve the SDG3 targets and leave no one behind, it is essential to close health inequality gaps within as well as between countries.

Paving the way to understanding female-headed households: Variation in household composition across 103 low- and middle-income countries.

Background: Female-headed households (FHHs) are regarded as disadvantaged. There are multiple social trajectories that can lead to women heading households. It is important to distinguish between these trajectories, as well as societal norms and contextual factors, to understand how and when are FHHs represented as a dimension of gender inequity. Our analysis defines and describes a typology of 16 FHH types (FHH16) based on demographic characteristics. Methods: This cross-sectional study used national Demographic Health Surveys (DHS) and Multiple Indicator Cluster Surveys (MICS) in 103 low- and middle-income countries (LMICs) to identify a typology of FHHs based on the family composition and additional household members. We performed descriptive analyses at the household level to generate median proportions of the FHH16 types and selected household characteristics. We conducted cluster analyses to explore FHH16 patterns across naturally grouped clusters of countries and described selected social and economic indicators at the ecological level. Results: The most common FHH16 types were those where the women household heads lived with children only, were alone, or lived with men, women, and children, but without a husband. In Africa and South Asia, the most common FHH was one where women heads resided with children only. In East Asia and the Pacific, the highest proportion of FHHs were those with men, women, and children. In MENA and Eastern Europe & Central Asia, households with women heads living alone were the most prevalent. Latin America had more FHHs with husbands, comparatively, and the most common FHHs were those with heads living alone or with children. Our exploratory cluster analysis generated five clusters with unique FHH16 patterns. The clusters had distinct geographic, contextual and economic characteristics. Conclusions: Our typology showed that FHHs are heterogeneous within and between countries. The ecological analysis emphasized further variation created by different societal and cultural factors. Research around their vulnerabilities and strengths needs to consider these factors and their influence on socioeconomic status and health-related outcomes within households headed by women.

Ethnic disparities in immunisation: analyses of zero-dose prevalence in 64 countries.

BACKGROUND: The Sustainable Development Goals (SDGs) recommend stratification of health indicators by ethnic group, yet there are few studies that have assessed if there are ethnic disparities in childhood immunisation in low-income and middle-income countries (LMICs). METHODS: We identified 64 LMICs with standardised national surveys carried out since 2010, which provided information on ethnicity or a proxy variable and on vaccine coverage; 339 ethnic groups were identified after excluding those with fewer than 50 children in the sample and countries with a single ethnic group. Lack of vaccination with diphtheria-pertussis-tetanus vaccine-a proxy for no access to routine vaccination or 'zero-dose' status-was the outcome of interest. Differences among ethnic groups were assessed using a χ2 test for heterogeneity. Additional analyses controlled for household wealth, maternal education and urban-rural residence. FINDINGS: The median gap between the highest and lowest zero-dose prevalence ethnic groups in all countries was equal to 10 percentage points (pp) (IQR 4-22), and the median ratio was 3.3 (IQR 1.8-6.7). In 35 of the 64 countries, there was significant heterogeneity in zero-dose prevalence among the ethnic groups. In most countries, adjustment for wealth, education and residence made little difference to the ethnic gaps, but in four countries (Angola, Benin, Nigeria and Philippines), the high-low ethnic gap decreased by over 15 pp after adjustment. Children belonging to a majority group had 29% lower prevalence of zero-dose compared with the rest of the sample. INTERPRETATION: Statistically significant ethnic disparities in child immunisation were present in over half of the countries studied. Such inequalities have been seldom described in the published literature. Regular analyses of ethnic disparities are essential for monitoring trends, targeting resources and assessing the impact of health interventions to ensure zero-dose children are not left behind in the SDG era.

Children of more empowered women are less likely to be left without vaccination in low- and middle-income countries: A global analysis of 50 DHS surveys.

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 both women's empowerment and child immunisation. Zero-dose was operationally defined as the proportion of children who failed to receive any doses of the diphtheria, pertussis, and tetanus containing vaccines (DPT). We measured women's empowerment using the SWPER Global, an individual-level indicator estimated for women aged 15-49 years who are married or in union and with three domains: social independence, decision-making and attitude towards violence. We estimated two summary measures of inequality, the slope index of inequality (SII) and the concentration index (CIX). Results were presented for individual and pooled countries. Results: In the country-level (ecological) analyses we found that the higher the proportion of women with high empowerment, the lower the zero-dose prevalence. In the individual level analyses, overall, children with highly-empowered mothers presented lower prevalence of zero-dose than those with less-empowered mothers. The social independence domain presented more consistent associations with zero-dose. In 42 countries, the lowest zero-dose prevalence was found in the high empowerment groups, with the slope index of inequality showing significant results in 28 countries. When we pooled all countries using a multilevel Poisson model, children from mothers in the low and medium levels of the social independence domain had respectively 3.3 (95% confidence interval (CI) = 2.3, 4.7) and 1.8 (95% CI = 1.5, 2.1) times higher prevalence of zero-dose compared to those in the high level. Conclusions: Our country-level and individual-level analyses support the importance of women's empowerment for child vaccination, especially in countries with weaker routine immunisation programs.

[Factors associated infant development in Brazilian children: baseline of the impact assessment of the Happy Child Program]. / Fatores associados ao desenvolvimento infantil em crianças brasileiras: linha de base da avaliação do impacto do Programa Criança Feliz.

The study aimed to assess socioeconomic, family, and individual factors associated with infant development (i.e., in the first year of life) among families with social vulnerability. This was a cross-sectional analysis of baseline data from a randomized trial. The study included 3,242 children < 12 months of age living in 30 municipalities from five regions of Brazil. The choice of states and municipalities was intentional, based on the implementation of the Brazilian Happy Child Program. The sample was selected among eligible children for the Brazilian Happy Child Program, and the objective was the promotion of infant development. The Ages and Stages Questionnaire (ASQ) was used to assess infant development. A three-level analytical model (state, municipality, and individuals), using the Wald test for heterogeneity and linear trend, estimated the mean ASQ-3 and 95% confidence interval (95%CI). The analyses were adjusted for potential confounders. Information was analyzed for 3,061 (94.4%) children with available data for ASQ-3. Infant development scores (total and in all the domains) were some 12% lower in preterm children and those with intrauterine growth restriction (small for gestational age). Lower scores were seen in children of mothers with low schooling, depressive symptoms, two or more children under seven years of age living in the household, and who did not report self-perceived support or help during the pregnancy. In conclusion, potentially modifiable characteristics (schooling, maternal depression, and prematurity/intrauterine growth restriction) showed greater impact on reducing the infant development score in all the target domains.

O objetivo deste artigo foi avaliar os fatores socioeconômicos, familiares e individuais associados ao desenvolvimento infantil no primeiro ano de vida, entre famílias em vulnerabilidade social. Trata-se de uma análise transversal, com dados da linha de base de um ensaio randomizado. O estudo incluiu 3.242 crianças < 12 meses de idade, residentes em 30 municípios de cinco regiões do Brasil. A escolha de estados e municípios foi intencional, tendo como base a implementação do Programa Criança Feliz. A amostra foi selecionada a partir de crianças elegíveis para o Programa Criança Feliz, cujo objetivo é promover a estimulação e o desenvolvimento infantil. O Ages and Stages Questionnaire (ASQ) foi utilizado para avaliação do desenvolvimento infantil. Um modelo de análise multinível em três níveis (estado, município e indivíduos), usando teste de Wald para heterogeneidade e tendência linear, estimou a média do ASQ-3 e intervalo de 95% de confiança (IC95%). Análises foram ajustadas para potenciais confundidores. Foram analisadas informações de 3.061 (94,4%) crianças com dados disponíveis para ASQ-3. Escores de desenvolvimento infantil (total e em todos os domínios) foram cerca de 12% menores em crianças nascidas pré-termo e com restrição do crescimento intrauterino (pequenas para idade gestacional). Observou-se menores escores em filhos de mães com baixa escolaridade, com sintomas de depressão, com duas ou mais crianças menores de sete anos residindo no domicílio e que não relataram autopercepção de apoio/ajuda durante a gestação. Conclui-se que características potencialmente modificáveis (escolaridade, depressão materna e prematuridade/restrição do crescimento intrauterino) apresentaram maior impacto na redução do escore de desenvolvimento em todos os domínios avaliados.

El objetivo fue evaluar los factores socioeconómicos, familiares e individuales, asociados al desarrollo infantil en el primer año de vida, entre familias con vulnerabilidad social. Se trata de un análisis transversal, con datos de la base de referencia de un ensayo aleatorio. El estudio incluyó a 3.242 niños < 12 meses de edad, residentes en 30 municipios de cinco regiones de Brasil. La elección de estados y municipios fue intencional, considerando como base la implementación del Programa Niño Feliz. La muestra se seleccionó a partir de niños elegibles para el Programa Niño Feliz, cuyo objetivo es promover la estimulación y el desarrollo infantil. Se utilizó el Ages and Stages Questionnaire (ASQ) para la evaluación del desarrollo infantil. Un modelo de análisis multinivel en tres niveles (estado, municipio e individuos), usando el test de Wald para la heterogeneidad y tendencia lineal, estimó la media del ASQ-3 y el intervalo de 95% de confianza (IC95%). Los análisis se ajustaron para potenciales factores de confusión. Se analizó información de 3.061 (94,4%) niños con datos disponibles para ASQ-3. Las puntuaciones de desarrollo infantil (total y en todos los dominios) fueron cerca de un 12% menores en niños nacidos pretérmino y con restricción del crecimiento intrauterino (pequeños para la edad gestacional). Se observaron menores puntuaciones en hijos de madres con baja escolaridad, con síntomas de depresión, con dos o más niños menores de siete años residiendo en el domicilio y que no informaron autopercepción de apoyo/ayuda durante la gestación. Se concluye que las características potencialmente modificables (escolaridad, depresión materna y prematuridad/restricción del crecimiento intrauterino) presentaron un mayor impacto en la reducción de la puntuación de desarrollo en todos los dominios evaluados.

Consumption of breast milk, formula and other non-human milk by children aged under 2 years: analysis of eighty-six low- and middle-income countries.

OBJECTIVE: To investigate the prevalence and socio-economic inequalities in breast milk, breast milk substitutes (BMS) and other non-human milk consumption, by children under 2 years in low- and middle-income countries (LMIC). DESIGN: We analysed the prevalence of continued breast-feeding at 1 and 2 years and frequency of formula and other non-human milk consumption by age in months. Indicators were estimated through 24-h dietary recall. Absolute and relative wealth indicators were used to describe within- and between-country socio-economic inequalities. SETTING: Nationally representative surveys from 2010 onwards from eighty-six LMIC. PARTICIPANTS: 394 977 children aged under 2 years. RESULTS: Breast-feeding declined sharply as children became older in all LMIC, especially in upper-middle-income countries. BMS consumption peaked at 6 months of age in low/lower-middle-income countries and at around 12 months in upper-middle-income countries. Irrespective of country, BMS consumption was higher in children from wealthier families, and breast-feeding in children from poorer families. Multilevel linear regression analysis showed that BMS consumption was positively associated with absolute income, and breast-feeding negatively associated. Findings for other non-human milk consumption were less straightforward. Unmeasured factors at country level explained a substantial proportion of overall variability in BMS consumption and breast-feeding. CONCLUSIONS: Breast-feeding falls sharply as children become older, especially in wealthier families in upper-middle-income countries; this same group also consumes more BMS at any age. Country-level factors play an important role in explaining BMS consumption by all family wealth groups, suggesting that BMS marketing at national level might be partly responsible for the observed differences.

Innovative methods to analyse the impact of gender norms on adolescent health using global health survey data.

BACKGROUND: Understanding how gender norms affect health is an important entry point into designing programs and policies to change norms and improve gender equality and health. However, it is rare for global health datasets to include questions on gender norms, especially questions that go beyond measuring gender-related attitudes, thus limiting gender analysis. METHODS: We developed five case studies using health survey data from six countries to demonstrate approaches to defining and operationalising proxy measures and analytic approaches to investigating how gender norms can affect health. Key findings, strengths and limitations of our norms proxies and methodological choices are summarised. FINDINGS: Case studies revealed links between gender norms and multiple adolescent health outcomes. Proxys for norms were derived from data on attitudes, beliefs, and behaviours, as well as differences between attitudes and behaviours. Data were cross-sectional, longitudinal, census- and social network-based. Analytic methods were diverse. We found that gender norms affect: 1) Intimate partner violence in Nigeria; 2) Unhealthy weight control behaviours in Brazil and South Africa; 3) HIV status in Zambia; 4) Health and social mobility in the US; and 5) Childbirth in Honduras. INTERPRETATION: Researchers can use existing global health survey data to examine pathways through which gender norms affect health by generating proxies for gender norms. While direct measures of gender norms can greatly improve the understanding of how gender affects health, proxy measures for norms can be designed for the specific health-related outcome and normative context, for instance by either aggregating behaviours or attitudes or quantifying the difference (dissonance) between them. These norm proxies enable evaluations of the influence of gender norms on health and insights into possible reference groups and sanctions for non-compliers, thus informing programmes and policies to shape norms and improve health.

Ethnic inequalities in health intervention coverage among Mexican women at the individual and municipality levels.

BACKGROUND: Using data from Mexico, the country with the largest indigenous population in Latin America, we describe ethnic inequalities in coverage with women's health interventions at individual and municipal levels. METHODS: Cross-sectional study using data from the National Health and Nutrition Survey 2018 and the Mexican Intercensal Survey 2015. We selected five outcomes: modern contraceptive use, content-qualified antenatal care (ANCq), and skilled birth attendant (SBA) for women aged 15-49 years; Pap smear test and mammogram among women aged 25-64 and 40-69 years respectively. Municipalities were classified into three groups by the percentage of indigenous population: <10%, 10% - 39%, and ≥40%. We calculated crude and adjusted coverage ratios (CR) and 95% confidence intervals (CI) using Poisson regression. FINDINGS: Women living in municipalities with indigenous population ≥40% were poorer, less educated, and more rural. Coverage was lower for indigenous than non-indigenous for modern contraceptive use (CR: 0·73; CI 0·65-0·83), ANCq (CR: 0·72; CI 0·62-0·83), SBA (CR: 0·83; CI 0·77-0·90) and undergoing a mammogram (CR: 0·54; CI 0·41-0·71), but not for Pap smears (CR: 0·94; CI 0·83-1·07). Coverage with the five interventions increased as the municipal proportions of indigenous population decreased, both for indigenous and non-indigenous women. Coverage gaps at municipal level tended to be wider than at individual level. INTERPRETATION: Both indigenous and non-indigenous women living in municipalities with high proportions of indigenous people were systematically excluded from reproductive and maternal interventions. Our findings suggest that social and health interventions targeted at the individual level should be complemented by structural interventions in municipalities with high proportions of indigenous people, including strengthening health and social services.

Desigualdades relacionadas con el ODS 3 en la salud de las mujeres, los niños y los adolescentes: línea de base para el monitoreo de los ODS en América Latina y el Caribe por medio de encuestas transversales nacionales / SDG3-related inequalities in women's, children's and adolescents' health: an SDG monitoring baseline for Latin America and the Caribbean using national cross-sectional surveys / Desigualdades relacionadas ao ODS 3 na saúde da mulher, da criança e do adolescente: linha de base para o monitoramento do ODS na América Latina e no Caribe por meio de pesquisas transversais nacionais

RESUMEN Objetivos. Los países de América Latina y el Caribe han realizado importantes avances hacia la consecución de las metas del Objetivo de Desarrollo Sostenible relacionado con la salud (ODS 3) a escala nacional. Sin embargo, persisten enormes desigualdades en salud en los países. Se presenta una línea de base de las desigualdades en salud en la región, contra la cual se puede monitorear el progreso hacia los ODS. Contexto. Se estudiaron 21 países de América Latina y el Caribe usando datos de encuestas de demografía y salud y encuestas de indicadores múltiples por conglomerados realizadas del 2011 al 2016. Participantes. En las encuestas se recopilan datos representativos a nivel nacional de mujeres y niños por medio del muestreo polietápico. En total, 288 207 mujeres y 195 092 niños participaron en las encuestas en los 21 países. Medición de los resultados. Se estudiaron cinco indicadores de intervenciones de salud relacionadas con la salud reproductiva y materna, la fecundidad de las adolescentes y las tasas de mortalidad neonatal y de menores de 5 años. Después se evaluaron las desigualdades en estos indicadores por medio de mediciones absolutas y relativas. Resultados. En la mayoría de los países se observaron gradientes geográficos en salud a escala subnacional en casi todos los indicadores correspondientes a las mujeres y la población infantil y adolescente. La cobertura de las principales intervenciones fue mayor en las zonas urbanas y los quintiles más ricos que en las zonas rurales y los quintiles más pobres. Los análisis por edad de la mujer mostraron que la cobertura de las adolescentes era menor que la cobertura de las mujeres adultas en lo que se refiere a los indicadores de planificación familiar. En la mayoría de los países se observaron también desigualdades en la mortalidad que favorecían a las zonas urbanas y a los ricos. Conclusiones. Los promedios regionales ocultan importantes desigualdades en salud entre los países, pero las estimaciones nacionales ocultan desigualdades incluso mayores entre subgrupos de mujeres, niños y adolescentes. Para alcanzar las metas del ODS 3 y no dejar a nadie atrás es esencial subsanar no solo las brechas de la desigualdad en salud entre los países sino también dentro de ellos.

ABSTRACT Objectives. Latin America and the Caribbean (LAC) countries have made important progress towards achieving the Sustainable Development Goal (SDG) targets related to health (SDG3) at the national level. However, vast within-country health inequalities remain. We present a baseline of health inequalities in the region, against which progress towards the SDGs can be monitored. Setting. We studied 21 countries in LAC using data from Demographic and Health Surveys and Multiple Indicator Cluster Survey carried out from 2011 to 2016. Participants. The surveys collect nationally representative data on women and children using multistage sampling. In total, 288 207 women and 195 092 children made part of the surveys in the 21 countries. Outcome measures. Five health intervention indicators were studied, related to reproductive and maternal health, along with adolescent fertility and neonatal and under-five mortality rates. Inequalities in these indicators were assessed through absolute and relative measures. Results. In most countries, subnational geographical health gradients were observed for nearly all women, child, and adolescent (WCA) indicators. Coverage of key interventions was higher in urban areas and among the richest, compared with rural areas and poorer quintiles. Analyses by woman's age showed that coverage was lower in adolescent girls than older women for family planning indicators. Pro-urban and pro-rich inequalities were also seen for mortality in most countries. Conclusions. Regional averages hide important health inequalities between countries, but national estimates hide still greater inequalities between subgroups of women, children and adolescents. To achieve the SDG3 targets and leave no one behind, it is essential to close health inequality gaps within as well as between countries.

RESUMO Objetivos. Os países da América Latina e do Caribe obtiveram avanços significativos rumo à consecução do Objetivo de Desenvolvimento Sustentável relacionado à saúde (ODS 3) no nível nacional. No entanto, enormes desigualdades em saúde persistem nos países. Apresenta-se uma linha de base das desigualdades em saúde na região, com referência à qual é possível monitorar o progresso rumo aos ODS. Contexto. Foram estudados 21 países da América Latina e do Caribe usando dados de pesquisas de demografia e saúde e pesquisas de grupos de indicadores múltiplos feitas de 2011 a 2016. Participantes. As pesquisas coletam dados nacionalmente representativos sobre mulheres e crianças, por meio de amostragem multietápica. No total, 288.207 mulheres e 195.092 crianças participaram das pesquisas nos 21 países. Medição dos resultados. Foram estudados cinco indicadores de intervenções de saúde relacionadas à saúde reprodutiva e materna, à fertilidade das adolescentes e às taxas de mortalidade neonatal e de menores de cinco anos. As desigualdades nesses indicadores foram então avaliadas, empregando medidas absolutas e relativas. Resultados. Gradientes geográficos de saúde nos níveis subnacionais foram observados na maioria dos países para quase todos os indicadores referentes às mulheres e à população infantil e adolescente. A cobertura das principais intervenções foi maior nas áreas urbanas e nos quintis mais ricos do que nas áreas rurais e nos quintis mais pobres. As análises por idade das mulheres mostraram que a cobertura das adolescentes era inferior à cobertura das mulheres adultas no que se refere aos indicadores de planejamento familiar. Além disso, foram observadas desigualdades na mortalidade que favoreciam as áreas urbanas e os ricos, na maioria dos países. Conclusões. As médias regionais mascaram desigualdades significativas na saúde entre os países, mas as estimativas nacionais mascaram desigualdades ainda maiores entre os subgrupos de mulheres, crianças e adolescentes. Para alcançar as metas do ODS 3 e não deixar ninguém para trás, é essencial abordar não apenas as lacunas da desigualdade em saúde entre os países, mas também dentro deles.

Abstract: The study aimed to assess socioeconomic, family, and individual factors associated with infant development (i.e., in the first year of life) among families with social vulnerability. This was a cross-sectional analysis of baseline data from a randomized trial. The study included 3,242 children < 12 months of age living in 30 municipalities from five regions of Brazil. The choice of states and municipalities was intentional, based on the implementation of the Brazilian Happy Child Program. The sample was selected among eligible children for the Brazilian Happy Child Program, and the objective was the promotion of infant development. The Ages and Stages Questionnaire (ASQ) was used to assess infant development. A three-level analytical model (state, municipality, and individuals), using the Wald test for heterogeneity and linear trend, estimated the mean ASQ-3 and 95% confidence interval (95%CI). The analyses were adjusted for potential confounders. Information was analyzed for 3,061 (94.4%) children with available data for ASQ-3. Infant development scores (total and in all the domains) were some 12% lower in preterm children and those with intrauterine growth restriction (small for gestational age). Lower scores were seen in children of mothers with low schooling, depressive symptoms, two or more children under seven years of age living in the household, and who did not report self-perceived support or help during the pregnancy. In conclusion, potentially modifiable characteristics (schooling, maternal depression, and prematurity/intrauterine growth restriction) showed greater impact on reducing the infant development score in all the target domains.
