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 measures in the identification process. For absolute ones, we selected people living below the poverty line, socioeconomic deprivation status and the UN-Habitat slum definition. We used different cut-off points for relative measures based on wealth distribution: 30%, 40%, 50%, and 60%. We analyzed all these measures according to the absence of electricity, improved drinking water and sanitation facilities, the proportion of children out-of-school, and any household member aged 10 or more with less than 6 years of education. We used the sample size, the gap between the poorest and richest groups, and the observed agreement between absolute and relative measures to identify the best measure. The best classification was based on 40% of the wealth since it has good discriminatory power between groups and median observed agreement higher than 60% in all selected cities. Using this measure, the median prevalence of absence of improved sanitation facilities was 82% among the poorer, and this indicator presented the highest inequalities. Educational indicators presented the lower prevalence and inequalities. Luanda, Ouagadougou, and N'Djaména were considered the worst performers, while Lagos, Douala, and Nairobi were the best performers. The higher the human development index, the lower the observed inequalities. When analyzing cities using nationally representative surveys, we recommend using the relative measure of 40% of wealth to characterize the poorest group. This classification presented large gaps in the selected outcomes and good agreement with absolute measures.

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 least four antenatal care visits (ANC4+), institutional birth, and three doses of DPT vaccine[diphtheria, pertussis and tetanus]) and health status (stunting in children under 5 years, neonatal and under-5 mortality rates) among the poor and non-poor in the most populous cities from 38 SSA countries. We analyzed 136 population-based surveys (year range 2000-2019), contrasting the poorest 40% of households (referred to as poor) with the richest 60% (non-poor). Coverage in the most recent survey was higher for the city non-poor compared to the poor for all interventions in virtually all cities, with the largest median gap observed for ANC4+ (13.5 percentage points higher for the non-poor). Stunting, neonatal, and under-5 mortality rates were higher among the poor (7.6 percentage points, 21.2 and 10.3 deaths per 1000 live births, respectively). The gaps in coverage between the two groups were reducing, except for ANC4, with similar median average annual rate of change in both groups. Similar rates of change were also observed for stunting and the mortality indicators. Continuation of these positive trends is needed to eliminate inequalities in essential health services and child survival in SSA cities.

Measures of women's empowerment based on individual-level data: a literature review with a focus on the methodological approaches.

Background: Quantifying women's empowerment has become the focus of attention of many international organizations and scholars. We aimed to describe quantitative indicators of women's empowerment that are based on individual-level data. Methods: In this scoping review, we searched PubMed, Scopus, Web of Science, Science Direct, Google, and Google Scholar for publications describing the operationalization of measures of women's empowerment. Results: We identified 36 studies published since 2004, half of them since 2019, and most from low- and middle-income countries. Twelve studies were based on data from the Demographic and Health Surveys and used 56 different variables from the questionnaires (ranging from one to 25 per study) to measure the overall empowerment of women 15-49 years. One study focused on rural women, two included married and unmarried women, and one analyzed the couple's responses. Factor analysis and principal component analysis were the most common approaches used. Among the 24 studies based on other surveys, ten analyzed overall empowerment, while the others addressed sexual and reproductive health (4 studies), agriculture (3) and livestock (1), water and sanitation (2), nutrition (2), agency (1), and psychological empowerment (1). These measures were mainly based on data from single countries and factor analysis was the most frequently analytical method used. We observed a diversity of indicator definitions and domains and a lack of consensus in terms of what the proposed indicators measure. Conclusion: The proposed women's empowerment indicators represent an advance in the field of gender and development monitoring. However, the empowerment definitions used vary widely in concept and in the domains/dimensions considered, which, in turn influence or are influenced by the adopted methodologies. It remains a challenge to find a balance between the need for a measure suitable for comparisons across populations and over time and the incorporation of country-specific elements.

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.

Differences in food consumption of the Brazilian population by race/skin color in 2017-2018.

OBJECTIVE: To evaluate food consumption in Brazil by race/skin color of the population. METHODS: Food consumption data from the Pesquisa de Orçamentos Familiares (POF - Household Budget Survey) 2017-2018 were analyzed. Food and culinary preparations were grouped into 31 items, composing three main groups, defined by industrial processing characteristics: 1 - in natura/minimally processed, 2 - processed, and 3 - ultra-processed. The percentage of calories from each group was estimated by categories of race/skin color - White, Black, Mixed-race, Indigenous, and Yellow- using crude and adjusted linear regression for gender, age, schooling, income, macro-region, and area. RESULTS: In the crude analyses, the consumption of in natura/minimally processed foods was lower for Yellow [66.0% (95% Confidence Interval 62.4-69.6)] and White [66.6% (95%CI 66.1-67.1)] groups than for Blacks [69.8% (95%CI 68.9-70.8)] and Mixed-race people [70.2% (95%CI 69.7-70.7)]. Yellow individuals consumed fewer processed foods, with 9.2% of energy (95%CI 7.2-11.1) whereas the other groups consumed approximately 13%. Ultra-processed foods were less consumed by Blacks [16.6% (95%CI 15.6-17.6)] and Mixed-race [16.6% (95%CI 16.2-17.1)], with the highest consumption among White [20.1% (95%CI 19.6-20.6)] and Yellow [24.5% (95%CI 20.0-29.1)] groups. The adjustment of the models reduced the magnitude of the differences between the categories of race/skin color. The difference between Black and Mixed-race individuals from the White ones decreased from 3 percentage points (pp) to 1.2 pp in the consumption of in natura/minimally processed foods and the largest differences remained in the consumption of rice and beans, with a higher percentage in the diet of Black and Mixed-race people. The contribution of processed foods remained approximately 4 pp lower for Yellow individuals. The consumption of ultra-processed products decreased by approximately 2 pp for White and Yellow groups; on the other hand, it increased by 1 pp in the consumption of Black, Mixed-race, and Indigenous peoples. CONCLUSION: Differences in food consumption according to race/skin color were found and are influenced by socioeconomic and demographic conditions.

Trends in the prevalence and social determinants of stunting in India, 2005-2021: findings from three rounds of the National Family Health Survey.

Objectives: To assess social determinants of stunting and the shifts in contributions of socio-demographic factors to national prevalence trends in India between 2005 and 2021. Methods: We leveraged data from three rounds of the National Family Health Survey (NFHS-3: 2005-2006, NFHS-4: 2015-2016, NFHS-5: 2019-2021) for 443 038 children under 5 years. Adjusted logistic regression models and a Kitigawa-Oaxaca-Blinder decomposition were deployed to examine how wealth, residence, belonging to a marginalised social group, maternal education and child sex contributed to changes in stunting prevalence. Results: The decrease in stunting prevalence was notably slower between NFHS-4 and NFHS-5 (annual average rate of reduction (AARR): 1.33%) than between NFHS-3 and NFHS-4 (AARR: 2.20%). The protective effect of high wealth diminished from 2015 onwards but persisted for high maternal education. However, an intersection of higher household wealth and maternal education mitigated stunting to a greater extent than either factor in isolation. Residence only predicted stunting in 2005-2006 with an urban disadvantage (adjusted OR: 1.18; 95% CI: 1.07 to 1.29). Children from marginalised social groups displayed increased likelihoods of stunting, from 6-16% in 2005-2006 to 11-21% in 2015-2016 and 2020-2021. Being male was associated with 6% and 7% increased odds of stunting in 2015-2016 and 2019-2021, respectively. Increased household wealth (45%) and maternal education (14%) contributed to decreased stunting prevalence between 2005 and 2021. Conclusions: Stunting prevalence in India has decreased across social groups. However, social disparities in stunting persist and are exacerbated by intersections of low household wealth, maternal education and being from a marginalised social group. Increased survival must be accompanied by needs-based interventions to support children and mitigate mutually reinforcing sources of inequality.

RESUMO OBJETIVO Avaliar o consumo alimentar no Brasil por raça/cor da pele da população. MÉTODOS Foram analisados dados de consumo alimentar da Pesquisa de Orçamentos Familiares 2017-2018. Alimentos e preparações culinárias foram agrupados em 31 itens, compondo três grupos principais, definidos por características do processamento industrial: 1 - in natura/minimamente processados, 2 - processados e 3 - ultraprocessados. O percentual de calorias de cada grupo foi estimado por categorias de raça/cor da pele - branca, preta, parda, indígena e amarela -, utilizando-se regressão linear bruta e ajustada para sexo, idade, escolaridade, renda, macrorregião e área. RESULTADOS Nas análises brutas, o consumo de alimentos in natura/minimamente processados foi menor para amarelos [66,0% (Intervalo de Confiança 95% 62,4-69,6)] e brancos [66,6% (IC95% 66,1-67,1)] que para pretos [69,8% (IC95% 68,9-70,8)] e pardos [70,2% (IC95% 69,7-70,7)]. Amarelos consumiram menos alimentos processados, com 9,2% das calorias (IC95% 7,2-11,1) enquanto os demais consumiram aproximadamente 13%. Ultraprocessados foram menos consumidos por pretos [16,6% (IC95% 15,6-17,6)] e pardos [16,6% (IC95% 16,2-17,1)], e o maior consumo ocorreu entre brancos [20,1% (IC95% 19,6-20,6)] e amarelos [24,5% (IC95% 20,0-29,1)]. O ajuste dos modelos reduziu a magnitude das diferenças entre as categorias de raça/cor da pele. A diferença entre pretos e pardos em relação aos brancos diminuiu, de 3 pontos percentuais (pp), para 1,2 pp no consumo de alimentos in natura/minimamente processados e as maiores diferenças remanescentes foram no consumo de arroz e feijão, com maior percentual na alimentação de pretos e pardos. A participação de alimentos processados permaneceu aproximadamente 4 pp menor para amarelos. O consumo de ultraprocessados diminuiu aproximadamente 2 pp para brancos e amarelos; por outro lado, aumentou 1 pp no consumo de pretos, pardos e indígenas. CONCLUSÃO Diferenças no consumo alimentar segundo raça/cor da pele foram encontradas e são influenciadas por condições socioeconômicas e demográficas.

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.

Obesity and health service utilization in Brazil: data from the National Health Survey.

BACKGROUND: Obesity, a complex public health problem, is generally associated with other chronic diseases. The association of obesity with health service utilization has been little investigated in low- and middle-income countries. This study aimed to analyze the association between obesity and health service utilization (considering those services related to hypertension and/or diabetes). METHODS: A cross-sectional, nationally-representative, study of Brazilians aged ≥18 years was conducted. Data from the National Health Survey (2013) for 59,402 individuals were analyzed, including measured weight and height. The association between body mass index (BMI) category (under/normal weight, overweight, and obesity) and health service utilization due to hypertension and/or diabetes was investigated using Poisson regression models (crude and adjusted). To analyze the health services utilization, the following variables were considered: 1) routine visits to a general doctor or health service; 2) referrals/consultations with a specialist; 3) prescribed exams done; and 4) hospital admission due to the disease or related complication. All analyses were stratified by sex. RESULTS: Compared with under/normal-weight individuals, subjects with obesity (both male and female) made roughly double the use of all health care services assessed. Men with hypertension that had obesity had a higher risk of hospital admission (adjusted PR = 2.55; 95%CI 1.81-3.61), than those with under/normal weight. Women with diabetes that had obesity had more referrals/consultations with specialists (adjusted PR = 2.56; 95%CI 1.94-3.38), than those with under/normal weight. CONCLUSIONS: The presence of obesity was associated with increased use of health care services for hypertension and/or diabetes, indicating greater demand for human resources and materials, and a greater burden on the national health system.

Changes in socioeconomic inequalities in food consumption among Brazilian adults in a 10-years period.

Objective: To evaluate changes in socioeconomic inequalities in food consumption in Brazil over a 10-year period. Methods: Data on 24-h recalls of adults (aged 20 years or more) from the 2008/9 (n = 26,327) and 2017/8 (n = 37,689). Brazilian Dietary Survey were analyzed. We used the Nova classification system to group food items and estimate the percentage of total energy from ultra-processed foods and plant-based natural or minimally processed foods. For sex and area of residence, we calculated the percentage points (p.p.) difference between the estimates for women and men, and rural and urban populations. Negative values indicate higher consumption among men or urban residents, positive values indicate higher consumption among women or rural residents, and zero indicates equality. For education and wealth levels we calculated the slope index of inequality (SII). The SII varies from -100 to 100, with positive values indicating higher consumption among more educated or wealthiest groups, negative values indicating higher consumption among less educated or poorest groups, and zero equality. Results: Over the period, we observed a reduction in the percentage of total energy from plant-based natural/minimally processed foods from 13.0 to 12.2% and an increase in that of ultra-processed foods from 17.0 to 18.3%. The urban population and those in the wealthier and more educated groups presented higher consumption of ultra-processed foods and lower consumption of plant-based natural/minimally processed foods in both survey years. Over the 10-year period, there was an overall reduction of the socioeconomic inequalities, mainly explained by the greater increase in ultra-processed food consumption by the rural population and those from the poorest and less educated groups (difference for area -7.2 p.p. in 2008/9 and -5.9 p.p. in 2017/8; SII for education 17.7 p.p. in 2008/9 and 13.8 p.p. in 2017/8; SII for wealth 17.0 p.p. in 2008/9 and 11.2 p.p. in 2017/8). Conclusion: Socioeconomic inequalities in food consumption decreased in Brazil, but it may lead to the overall deterioration of the dietary quality of the more vulnerable groups.

Growth patterns by sex and age among under-5 children from 87 low-income and middle-income countries.

INTRODUCTION: Although boys tend to be more affected by linear growth faltering than girls, little is known about sex differences across distinct age groups. We aimed to compare sex differences in linear growth throughout the first 5 years of life among children from low-income and middle-income countries. METHODS: We analysed 87 cross-sectional Demographic and Health Surveys and Multiple Cluster Indicator Surveys (2010-2019). Growth was expressed as height-for-age z-scores (HAZ) based on the 2006 WHO Growth Standards. Sex-specific means were estimated for each country and results were pooled through random-effects meta-analysis for all children and by 12-month age groups. Using linear regression, we assessed the association between sex differences in HAZ and gross domestic product as a proxy for national economic development. RESULTS: Boys presented lower mean HAZ than girls in the first 30 months. Sex differences were mostly absent between 30 and 45 months, and in several countries, girls had lower HAZ at ages over 45 months. The pooled sex difference (boys minus girls) for the whole sample was -0.10 (95% CI -0.12 to -0.08). The difference was -0.17 (95% CI -0.20 to -0.14) at 0-11 months and -0.22 (95% CI -0.25 to -0.19) at 12-23 months. This was followed by a narrowing of the sex gap to -0.10 (95% CI -0.13 to -0.07) and -0.04 (95% CI -0.07 to -0.01) among children aged 24-35 and 36-47 months, respectively. At 48-59 months, there was evidence of female disadvantage; the mean height-for-age of boys was 0.02 (95% CI 0.00 to 0.05) SDs higher than for girls. Ecological analyses showed that in all age groups, male disadvantage decreased with increasing national income, and this was no longer present for the 4-year-old children, particularly in wealthier countries. CONCLUSION: Male disadvantage in linear growth is most evident in the first years, but by the age of 4 years, the sex gap has mostly disappeared, and in some countries, the gap has been reversed.

Levels and potential drivers of under-five mortality sex ratios in low- and middle-income countries.

BACKGROUND: Non-biological childhood mortality sex ratios may reflect community sex preferences and gender discrimination in health care. OBJECTIVE: We assessed the association between contextual factors and gender bias in under-five mortality rates (U5MR) in low- and middle-income countries. METHODS: Full birth histories available from Demographic and Health Surveys and Multiple Indicator Cluster Surveys (2010-2018) in 80 countries were used to estimate U5MR male-to-female sex ratios. Expected sex ratios and their residuals (difference of observed and expected) were derived from a linear regression model, adjusted for overall mortality. Negative residuals indicate more likelihood of discrimination against girls, and we refer to this as a measure of potential gender bias. Associations between residuals and national development and gender inequality indices and with survey-derived child health care indicators were tested using Spearman's correlation. RESULTS: Mortality residuals for under-five mortality were not associated with national development, education, religion, or gender inequality indices. Negative residuals were more common in countries where boys were more likely to be taken to health services than girls (rho -0.24, 95% confidence interval -0.45, -0.01). CONCLUSIONS: Countries where girls were more likely to die than boys, accounting for overall mortality levels, were also countries where boys were more likely to receive health care than girls. Further research is needed to understand which national characteristics explain the presence of gender bias, given that the analyses of development levels and gender equality did not discriminate between countries with or without excess mortality of girls. Reporting on child mortality separately by sex is required to enable such advances.

[Consumption of fruits and the association with ultra-processed food intake in Brazil in 2008-2009]. / Consumo de frutas e associação com a ingestão de alimentos ultraprocessados no Brasil em 2008-2009.

The scope of this study was to describe the consumption of fruit in Brazil and its association with the intake of ultra-processed (UP) foods in a representative sample of 32,900 individuals from the 2008-2009 Household Budget Survey. The association between calory contribution of fruit to the diet and quintiles of UP food intake was analyzed using linear regression. Fruit accounted for just over 5% of the calories, about half of which (2.4%) was in the form of juice. Men revealed lower consumption than women, and consumption increased with increasing age, income, and schooling. An inverse association between consumption of whole fruits and UP food was observed. Among the individuals who reported consuming fruit (68%), there was little diversity (mean: 1.16 types/day). The fruit most consumed included orange, banana, and apple. Whole fruit was consumed mainly at lunchtime and as snacks. The consumption was inversely associated with UP food intake at lunch, afternoon snack, and dinner. Juices were consumed mainly at lunchtime and did not vary with UP food intake. Higher fruit consumption outside the home occurred in all quintiles of UP food intake. Low fruit intake in Brazil and the association with UP consumption highlight the need for initiatives to promote healthy eating.

O objetivo deste estudo foi descrever o consumo de frutas no Brasil e a associação com a ingestão de alimentos ultraprocessados (UP) em amostra representativa de 32.900 brasileiros da Pesquisa de Orçamentos Familiares 2008-2009. A associação entre a participação calórica (% energia) das frutas na dieta e quintos de consumo de UP foi analisada por meio de regressão linear. Frutas representaram 5% das calorias, sendo cerca de metade (2,4%) como suco. Homens apresentaram consumo inferior ao das mulheres e houve maior consumo com aumento da idade, renda e escolaridade. Foi observada associação inversa entre consumo de frutas inteiras e UP. Dentre os indivíduos que consumiram frutas (68%) houve pouca diversidade (média: 1,16 tipos/dia). As frutas mais consumidas foram laranja, banana e maçã. Consumiu-se frutas inteiras principalmente nos horários de almoço e lanches e o consumo foi inversamente associado com a ingestão de UP no almoço, lanche da tarde e jantar. Os sucos foram mais consumidos no almoço e não variaram com o consumo de UP. Maior consumo de frutas fora do domicílio se repetiu em todos os quintos de UP. A baixa ingestão de frutas no Brasil e a associação com UP reforçam a necessidade de iniciativas de promoção da alimentação saudável.

Among the individuals who reported consuming fruit (68%), there was little diversity (mean: 1.16 types/day). The fruit most consumed included orange, banana, and apple. Whole fruit was consumed mainly at lunchtime and as snacks. The consumption was inversely associated with UP food intake at lunch, afternoon snack, and dinner. Juices were consumed mainly at lunchtime and did not vary with UP food intake. Higher fruit consumption outside the home occurred in all quintiles of UP food intake. Low fruit intake in Brazil and the association with UP consumption highlight the need for initiatives to promote healthy eating.

A scoping review of methods for assessment of sex differentials in early childhood mortality.

BACKGROUND: While assessment of sex differentials in child mortality is straightforward, their interpretation must consider that, in the absence of gender bias, boys are more likely to die than girls. The expected differences are also influenced by levels and causes of death. However, there is no standard approach for determining expected sex differences. METHODS: We performed a scoping review of studies on sex differentials in under-five mortality, using PubMed, Web of Science, and Scopus databases. Publication characteristics were described, and studies were grouped according to their methodology. RESULTS: From the 17,693 references initially retrieved we included 154 studies published since 1929. Indian, Bangladeshi, and Chinese populations were the focus of 44% of the works, and most studies addressed infant mortality. Fourteen publications were classified as reference studies, as these aimed to estimate expected sex differentials based upon the demographic experience of selected populations, either considered as gender-neutral or not. These studies used a variety of methods - from simple averages to sophisticated modeling - to define values against which observed estimates could be compared. The 21 comparative studies mostly used life tables from European populations as standard for expected values, but also relied on groups without assuming those values as expected, otherwise, just as comparison parameters. The remaining 119 studies were categorized as narrative and did not use reference values, being limited to reporting observed sex-specific estimates or used a variety of statistical models, and in general, did not account for mortality levels. CONCLUSION: Studies aimed at identifying sex differentials in child mortality should consider overall mortality levels, and report on more than one age group. The comparison of results with one or more reference values, and the use of statistical testing, are strongly recommended. Time trends analyses will help understand changes in population characteristics and interpret findings from a historical perspective.

The double burden of malnutrition in under-five children at national and individual levels: observed and expected prevalence in ninety-three low- and middle-income countries.

OBJECTIVE: To assess whether the observed prevalence of the double burden of malnutrition (DBM) would be higher than expected on the basis of chance, through analyses at national, wealth quintile and individual child levels. DESIGN: We selected nationally representative surveys from low- and middle-income countries (LMIC) carried out since 2005 with anthropometric measures on children under 5 years of age. Household wealth was assessed through asset indices. The expected prevalence of DBM was estimated by multiplying the prevalence of stunting (low height/length for age) and overweight (high weight for height/length). The WHO recommended cut-offs (20% for stunting and 10% for overweight) that were used to define DBM at national level. DBM at individual level was defined as co-occurrence of stunting and overweight in the same child. SETTING: Nationally representative surveys from ninety-three LMIC. PARTICIPANTS: A total of 825 633 children were studied. RESULTS: DBM at national level was observed in five countries, whereas it would be expected to occur in eleven countries. Six countries did not present evidence of DBM at national level but did so in at least one wealth quintile. At individual level, thirty countries (32·3%) showed higher prevalence of DBM than would be expected, but most differences were small except for Syria, Azerbaijan, Albania and Egypt. CONCLUSIONS: The observed number of countries or socio-economic subgroups within countries with the DBM using recommended thresholds was below what would be expected by chance. However, individual-level analyses showed that one-third of countries presented higher prevalence of DBM than would be expected.

Ciência & Saúde Coletiva - 25 years: contributions to pregnancy, delivery, and childhood studies. / Ciência & Saúde Coletiva - 25 anos: contribuição para os estudos sobre gestação, parto e infância.

We reviewed the scientific production on maternal health and the health of children under ten years of age, published in Journal Ciência & Saúde Coletiva during the last 25 years, focusing on quantitative studies. The authors' characteristics, populations under study, thematic areas, and methodology are described. A total of 170 publications were identified and grouped into 12 major themes. Pregnancy, delivery, and puerperium were the subject of 47 studies, followed by child anthropometric assessments (29), breastfeeding (24), and mortality (13). The selected publications represented 3.5% of the total original papers published by the Journal since its creation in 1996 and about 5% of the publications in the 2015-2020 period. The primary data sources were health service records, information systems, and population surveys. The cross-sectional design was used in 113 of the 170 articles, and 70% covered only one municipality. The Southeast and Northeast Regions of Brazil were the target of most studies, and the North Region was the least represented. The publications reflect the complexity of maternal and child health themes, with a particular focus on the importance of the Unified Health System and showing how open access data can contribute to public health research.

Association between ethnicity and under-5 mortality: analysis of data from demographic surveys from 36 low-income and middle-income countries.

BACKGROUND: The UN Sustainable Development Goals (SDGs) call for stratification of social indicators by ethnic groups; however, no recent multicountry analyses on ethnicity and child survival have been done in low-income and middle-income countries (LMICs). METHODS: We used data from Demographic and Health Surveys and Multiple Indicator Cluster Surveys collected between 2010 and 2016, from LMICs that provided birth histories and information on ethnicity or a proxy variable. We calculated neonatal (age 0-27 days), post-neonatal (age 28-364 days), child (age 1-4 years), and under-5 mortality rates (U5MRs) for each ethnic group within each country. We assessed differences in mortality between ethnic groups using a likelihood ratio test, Theil's index, and between-group variance. We used multivariable analyses of U5MR by ethnicity to adjust for household wealth, maternal education, and urban-rural residence. FINDINGS: We included data from 36 LMICs, which included 2 812 381 livebirths among 415 ethnic groups. In 25 countries, significant differences in U5MR by ethnic group were identified (all p<0·05 likelihood ratio test). In these countries, the median mortality ratio between the ethnic groups with the highest and lowest U5MRs was 3·3 (IQR 2·1-5·2; range 1·5-8·5), whereas among the remaining 11 countries, the median U5MR ratio was 1·9 (IQR 1·7-2·5; range 1·4-10·0). Ethnic gaps were wider for child mortality than for neonatal or post-neonatal mortality. In nearly all countries, adjustment for wealth, education, and place of residence did not affect ethnic gaps in mortality, with the exception of Guatemala, India, Laos, and Nigeria. The largest ethnic group did not have the lowest U5MR in any of the countries studied. INTERPRETATION: Significant ethnic disparities in child survival were identified in more than two-thirds of the countries studied. Regular analyses of ethnic disparities are essential for monitoring trends, targeting, and assessing the impact of health interventions. Such analyses will contribute to the effort towards leaving no one behind, which is at the centre of the SDGs.

Religious affiliation and immunization coverage in 15 countries in Sub-Saharan Africa.

BACKGROUND: Although religious affiliation has been identified as a potential barrier to immunization in some African countries, there are no systematic multi-country analyses, including within-country variability, on this issue. We investigated whether immunization varied according to religious affiliation and sex of the child in sub-Saharan African (SSA) countries. METHODS: We used data from 15 nationally representative surveys from 2010 to 2016. The major religious groups were described by country in terms of wealth, residence, and education. Proportions of fully immunized and unvaccinated children were stratified by country, maternal religion, and sex of the child. Poisson regression with robust variance was used to assess whether the outcomes varied according to religion, with and without adjustment for the above cited sociodemographic confounders. Interactions between child sex and religion were investigated. RESULTS: Fifteen countries had >10% of families affiliated with Christianity and >10% affiliated with Islam, and four also had >10% practicing folk religions. In general, Christians were wealthier, more educated and more urban. Nine countries had significantly lower full immunization coverage among Muslims than Christians (pooled prevalence ratio = 0.81; 95%CI: 0.79-0.83), of which seven remained significant after adjustment for confounders (pooled ratio = 0.90; 0.87-0.92). Four countries had higher coverage among Muslims, of which two remained significant after adjustment. Regarding unvaccinated children, six countries showed higher proportions among Muslims, all of which remained significant after adjustment [crude pooled ratio = 1.83 (1.59-2.07); adjusted = 1.31 (1.14-1.48)]. Children from families practicing folk religions did not show any consistent patterns in immunization. Child sex was not consistently associated with vaccination. CONCLUSION: Muslim religion was associated with lower vaccine coverage in several SSA countries, both for boys and girls. The involvement of religious leaders is essential for increasing immunization coverage and supporting the leave no one behind agenda of the Sustainable Development Goals.
