Exposure to conflict and child health outcomes: evidence from a large multi-country study

BackgroundPrevious research has consistently found evidence of poor health outcomes among children living in conflict areas. However, the methodological focus of these studies has largely been on case studies, chart or registry reviews, qualitative studies, and single country studies. This reflects the need for a comprehensive multi-country analysis of the associations between conflicts and child health over a longer period. This study analyses the adverse impact of exposure to different types of conflicts from in utero to five years of age, on several child health measures across a large group of countries. Our analysis pools data from multiple countries and time-points, to provide robust evidence on the relationship between conflict and child health.MethodsGeo-referenced data on various forms of conflict are combined with the Demographic Health Survey dataset, to construct a large unique database of 590,488 pre-school age children across 52 developing countries over the period 1997 to 2018. Our analysis exploits the within-country differences in children’s exposure to conflict from in utero to age five, to estimate its association with health outcomes. Our multivariate regression models estimate the links between conflict exposure and child health outcomes, measured using child nutrition outcomes (height-for-age and weight-for-age z-scores) and immunization status.Results and conclusionsEmpirical estimates show that even after controlling for a large array of socio-economic and demographic characteristics and location fixed effects, conflict exposure is negatively associated with child nutrition and immunization, across all our measures of conflict. These findings are robust across a range of specifications, alternative measures of conflict and sub-samples.

Association of maternal characteristics with child feeding indicators and nutritional status of children under-two years in Rural Ghana

BackgroundOptimal nutrition during the first two years of a child’s life is critical for the reduction of morbidity and mortality. In Ghana, majority of children miss out on optimal nutrition and only few (13%) of children receive a Minimum Acceptable Diet (MAD). Several studies have investigated the influence of community-level factors on infants and young children feeding (IYCF) practices. However, little is known about the influence of maternal factors on IYCF practices in rural settings. Therefore, this study assessed the influence of maternal factors on the feeding indicators and nutritional status of children aged 6–23 months in two administrative districts in Ghana.MethodsData were collected among 935 mothers who had children aged 6–23 months and accessed 21 Child Welfare Clinics within the study area. The study involved a face- to-face interview using structured questionnaires to capture maternal characteristics, dietary intake and anthropometric measurements of children. Multivariate logistic regression was used to study the association between maternal factors and child nutrition outcomes (MAD, dietary diversity score (DDS) and anthropometric indicators) using Stata 16.0 software.ResultsBeing employed (AOR = 3.07, 95% CI: 1.71—5.49, p < 0.001) and attaining secondary or higher education (AOR = 2.86, 95% CI: 1.42—5.78, p = 0.003) were significant predictors of children receiving MAD. Similarly, having an average decision-making autonomy increased the child’s odds of receiving MAD (AOR = 1.68, 95% CI: 1.02—2.76, p = 0.040). Children of mothers who attained secondary or a higher level of education (AOR = 0.59, 95% CI: 0.36 -0.97, p = 0.040) and those whose mothers were employed (AOR = 0.71, 95% CI: 0.47—1.07, p = 0.043) were associated with a reduced risk of underweight and stunting respectively. Children of mothers with average financial independence status were more likely to receive diversified meals (AOR = 1.55, 95% CI: 1.01–2.38, p = 0.045).ConclusionsHigh educational level and being employed have positive influence on MAD, stunting and underweight of children. High decision-making power and average financial independence of mothers are good predictors of children receiving MAD. Family planning, women empowerment in decision-making, providing employment opportunities for mothers and promoting girl-child education are recommended.

Participating in a Nutrition-Sensitive Agriculture Intervention Is Not Associated with Less Maternal Time for Care in a Rural Ghanaian District

Nutrition-sensitive agriculture (NSA) interventions may increase farm-related work for mothers, with consequences for child nutrition. The Nutrition Links (NL) intervention provided mothers with poultry, gardening inputs, technical support, and education to improve livelihoods and child nutrition outcomes in rural Ghana. Our objective was to compare time allocated to child care by a cross-section of mothers in the intervention group of the NL intervention with the control group (NCT01985243). A cross-section of NL mother-child pairs was included in a time allocation substudy [intervention (NL-I) n=74 and control (NL-C) n=69]. In-home observations of the mother-child pair were conducted for 1 min, every 5 min, for 6 h. Observations were categorized into 4 nonoverlapping binary variables as follows: 1) maternal direct care, 2) maternal supervisory care, 3) allocare, and 4) no direct supervision. Allocare was defined as care by another person in the presence or absence of the mother. Any care was defined as the observation of maternal direct care, maternal supervisory care, or allocare. Generalized linear mixed models with binomial data distribution were used to compare the child care categories by group, adjusting for known covariates. Maternal direct care (OR=1.07; 95% CI: 0.89, 1.28) and any care (OR=1.56; 95% CI: 0.91, 2.67) did not differ by intervention group. However, there was a higher odds of allocare (OR=1.36; 95% CI: 1.04, 1.79) in NL-I than in NL-C women. Maternal participation in an NSA intervention was not associated with a decrease in time spent directly on child care but was associated with an increase in care from other household and community members.The clinicaltrials.gov number provided is for the main NL intervention and not this current substudy.

Do unwanted children face growth penalties in resource poor environments? Evidence from Roma Settlements in Serbia.

In a high fertility context, research on the relationship between parental investment, unwanted births and child nutritional outcomes is limited. The implications may be especially relevant for children coming from the most disadvantaged backgrounds and at increased risk of nutritional deprivation. This study assessed the association between maternal investment, unwanted births disaggregated into mistimed and unwanted children, and child nutritional outcomes in a poor population of Serbian Roma. Multiple Indicator Cluster Surveys rounds 5 and 6 data for Serbian Roma settlements were used to account for the association between two measures of maternal investment: weight at birth and parity, and mistimed and unwanted children, and children height-for-age z-score (HAZ), weight-for-age z score (WAZ) and weight-for- height z-score (WHZ). The sample included 130 children aged 0-24 months. The child variables were age, gender, and birth order, while maternal independent variables included age, literacy and access to improved toilet facility as proxies for socioeconomic status. Children born with low birth weight (lower maternal investment in utero) face a significant deficit in terms of their nutritional outcomes, measured by HAZ and WAZ. The effect was aggravated for height if the child was unwanted while there was a positive relationship between access to improved toilet facility and WHZ. Unwanted children were of higher birth order, with older, higher parity mothers than mistimed children. Many of the Roma children may be at risk of undernutrition, however, Roma children who received lower maternal investment in utero, unwanted and living in poorest households may face additional risk.

Does money matter for child nutrition? Exploration of a preschool nutrition program in rural South-Central China

ObjectivesThe aim of this study was to examine the relationship between poverty and children's nutritional outcomes. MethodsDrawing on a 2018 survey of the preschool nutrition program conducted in the Xiangxi Autonomous Prefecture, Hunan Province, China, we applied propensity score matching to estimate the average treatment effects on the treated children. ResultsThe most striking result was that although poverty is often used as predictive of poor childhood nutrition, this effect was only significant for weight-for-age z-score and height-for-age z-score, but not for other nutritional indicators, cognition, or social emotional indexes. The results varied using different measures of poverty. The weak linkage between poverty and children's nutritional outcomes was confirmed by a series of robustness checks by changing the covariates for matching, adopting other matching methods, using bootstrapping standard errors, and building on machine learning tools. ConclusionsA single tool of small money transfer would have limited effects, but considerable income increases that lift the poor out of poverty are important for the poor. Additionally, a mixed tool of financial support and nutritional knowledge may lead to better outcomes, especially for those living above the poverty line.

A Causal Mediation Analysis for Investigating the Effect of a Randomized Cash-Transfer Program in Nicaragua.

Mediation analysis can be applied to data from randomized trials of health and social interventions to draw causal inference concerning their mechanisms. We used data from a cluster-randomized trial in Nicaragua, fielded between 2000 and 2002, to investigate whether the impact of providing access to a conditional cash-transfer program on child nutritional outcomes was mediated by child health check-ups and household dietary diversity. In a sample of 443 children 6-35 months old, we estimated the controlled direct (CDE) effect of random assignment on measured height-for-age z scores had we intervened so that all children received a health check-up and had the same level of household dietary diversity, using inverse-probability weighted marginal structural models to account for mediator-outcome confounding. Sensitivity analyses corrected the CDE for potential nondifferential error in the measurement of dietary diversity. Treatment assignment increased height-for-age z score by 0.37 (95% CI: 0.05, 0.69) standard deviations. The CDE was 0.20 (95% CI: -0.17, 0.57) standard deviations, suggesting nearly one-half of the program's impact on child nutrition would be eliminated had we intervened on these factors, although estimates were relatively imprecise. This study provides an illustration of how causal mediation analysis can be applied to examine the mechanisms of multifaceted interventions.

Prevalence of smoking and smokeless tobacco use during breastfeeding: A cross-sectional secondary data analysis based on 0.32 million sample women in 78 low-income and middle-income countries.

SummaryBackgroundSmoking and smokeless tobacco use during the postpartum period is well studied in high-income countries, whereas low-income and middle-income countries (LMICs) lack evidence.MethodsIn this cross-sectional study we used data from the Demographic and Health Surveys (DHS) and Multiple Indicator Cluster Surveys (MICS) conducted in 78 LMICs between January 2010 and December 2019 to study tobacco use among 0.32 million sample lactating women. Age-standardized prevalence of smoking and smokeless tobacco use was estimated and presented with a 95% Confidence Interval (CI) for 78 LMICs. Pooled estimates overall and by WHO regions were obtained using random-effects meta-analyses. Country-level and community-level variance to understand contextual factors was also quantified using multilevel modelling.FindingsPooled prevalence of any tobacco use among breastfeeding women in LMICs was 3.61% (95% CI 3.53–3.70); with the lowest prevalence in regions of the Americas (1.44%, 1.26–1.63) and the highest in the Southeast Asia region (6.13%, 6.0–6.27). The pooled prevalence of tobacco smoking was reported to be 1.16% (1.11–1.21), with the highest prevalence in the Eastern Mediterranean region (4.27%, 3.88–4.67) and the lowest in the African region (0.81%, 0.76–0.86). The pooled prevalence of smokeless tobacco use was reported to be 2.56% (2.49–2.63), with the highest prevalence in the Southeast Asia region (4.92%, 4.80–5.04). Illiterate and poor women in LMICs bore the enormous burden of tobacco use.InterpretationThe prevalence of smoking and smokeless tobacco use among lactating women in LMICs varied considerably across different WHO regions. Considering the cross-sectional design of the study, caution is required while interpreting the results. To improve mothers' and children's health and nutrition outcomes and reduce health inequalities in LMICs, reducing tobacco use through evidence-based interventions is critical.FundingNone.

Association between mother’s work status and child stunting in urban slums: a cross-sectional assessment of 346 child-mother dyads in Dhaka, Bangladesh (2020)

BackgroundA growing literature highlights the increased risk of stunting among children growing up in informal or slum settlements. Despite relatively high rates of female labor force participation in slums, there is limited evidence on relationship between mother’s work participation and nutritional outcomes of children in these settings.MethodsWe conducted a cross-sectional study in two large slums (Korail and Tongi) of Dhaka and Gazipur, Bangladesh to assess the association between maternal work and childhood stunting in a low-income urban context. Logistic regression models estimated unconditional and conditional associations between maternal work status and 1) child stunting, 2) child morbidity and dietary intake, and 3) health and hygiene behaviors. Subgroup analyses were done by type of child care support available.ResultsAfter adjusting for variations in individual and household level characteristics, we found that children of working mothers had nearly twice the odds of being stunted than children of non-working mothers (OR 1.84, 95%CI 1.05-3.23). Large differences in stunting were found by available care support: compared to children of non-working mothers, children of working mothers with nuclear-type family support had 4.5 times increased odds of stunting (OR 4.49, 95%CI 1.81-11.12), while no odds differential was found for children of working mothers with an extended-type family support (OR 0.69, 95%CI 0.30-1.59).ConclusionsMaternal employment is associated with a substantial increase in the odds of child stunting in the slum areas studied. Given that these effects only appear to arise in the absence of adequate family support, integrating appropriate childcare support measures for low-income urban working mothers might be an effective strategy to help reduce the prevalence of chronic undernutrition among slum children.

Disruptions, restorations and adaptations to health and nutrition service delivery in multiple states across India over the course of the COVID-19 pandemic in 2020: An observational study.

BackgroundModeling studies estimated severe impacts of potential service delivery disruptions due to COVID-19 pandemic on maternal and child nutrition outcomes. Although anecdotal evidence exists on disruptions, little is known about the actual state of service delivery at scale. We studied disruptions and restorations, challenges and adaptations in health and nutrition service delivery by frontline workers (FLWs) in India during COVID-19 in 2020.MethodsWe conducted phone surveys with 5500 FLWs (among them 3118 Anganwadi Workers) in seven states between August–October 2020, asking about service delivery during April 2020 (T1) and in August-October (T2), and analyzed changes between T1 and T2. We also analyzed health systems administrative data from 704 districts on disruptions and restoration of services between pre-pandemic (December 2019, T0), T1 and T2.ResultsIn April 2020 (T1), village centers, fixed day events, child growth monitoring, and immunization were provided by <50% of FLWs in several states. Food supplementation was least disrupted. In T2, center-based services were restored by over a third in most states. Administrative data highlights geographic variability in both disruptions and restorations. Most districts had restored service delivery for pregnant women and children by T2 but had not yet reached T0 levels. Adaptations included home delivery (60 to 96%), coordinating with other FLWs (7 to 49%), and use of phones for counseling (~2 to 65%). Personal fears, long distances, limited personal protective equipment, and antagonistic behavior of beneficiaries were reported challenges.ConclusionsServices to mothers and children were disrupted during stringent lockdown but restored thereafter, albeit not to pre-pandemic levels. Rapid policy guidance and adaptations by FLWs enabled restoration but little remains known about uptake by client populations. As COVID-19 continues to surge in India, focused attention to ensuring essential services is critical to mitigate these major indirect impacts of the pandemic.

The association between micronutrient powder delivery patterns and caregiver feeding behaviors in rural China

BackgroundHigh adherence and proper usage of micronutrient powder (MNP) influence child nutritional outcomes, yet few studies explore the role of delivery patterns. This study explores the association between MNP delivery patterns and MNP feeding behaviors among Han and minority caregivers in rural Western China.MethodsIn August 2019, a total of 1021 caregiver-child pairs were selected through a four-stage cluster sampling process. A cross-sectional survey collected information on caregiver demographics, MNP delivery patterns (channel and frequency), and MNP feeding behaviors (proper usage and adherence). Using logistic regression, we examined which delivery channels and delivery frequencies were associated with proper usage and high adherence.ResultsThe results indicated that minority caregivers had lower levels of proper MNP usage than did Han caregivers (89.2%), with Tibetan caregivers’ reporting the lowest rates of adherence (32.6%). Logistic regression revealed that that township-based channel was significantly correlated with proper usage among Tibetan and Yi caregivers (Odds Ratio, OR = 2.0, p < 0.01; and OR = 3.5, p < 0.001). Overall, the township-based and home-visit channels were significantly correlated with high adherence (OR = 1.7 and OR = 2.3, respectively; p < 0.001); delivery frequency was significantly correlated with high adherence (2 months: OR = 2.2, p < 0.001 and ≤ 1 month: OR = 3.5, p < 0.001) but not correlated with proper usage among the whole sample and individual ethnic groups.ConclusionsIn conclusion, the study finds evidence of a correlation between MNP delivery channel and both proper usage and high adherence as well as a correlation between MNP delivery frequency and high adherence.

The Indirect Impact of Smallholder Vegetable Production on Children's Nutrition Outcomes in Rural Vietnam

Childhood undernutrition, particularly stunting, wasting, and micronutrient deficiencies, remains a major health concern in rural Vietnam. While literature suggests leveraging agriculture to improve child nutrition via agricultural diversification, market engagement, and women's empowerment, very few studies have empirically explored how smallholder vegetable production can influence household nutrition. This paper examines the association of household-level vegetable diversity, market access, and market participation with nutrition outcome measures of children in smallholder households. We use a cross-sectional household dataset, collected in 2016 in northwest Vietnam, covering 234 children aged 6–60 months. We estimate and compare the results of regression models using three-stage least squares (3SLS), ordinary least squares (OLS), logistic regression, and seemingly unrelated regression (SUR), to explore variations in six nutrition outcome measures: height-for-age z-score (HAZ), weight-for-height z-score (WHZ), weight-for-age z-score (WAZ), stunting, wasting, and underweight. Our results suggest smallholder vegetable production has a significant indirect association with children's nutrition status via market participation. Market participation is an important factor in improving girls' HAZ and WHZ, and in reducing the probability of boys being stunted and underweight. The additional income from selling vegetables allows households to purchase nutritious food, which is likely to have a positive impact on children's nutrition outcomes.

Ecological Approach to Family-Style, Multilevel Child Care Intervention: Formative Evaluation Using RE-AIM Framework

ObjectiveConduct formative evaluation of Ecological Approach to Family-Style Dining (EAT) Intervention. DesignQualitative semistructured interviews and demographic surveys. SettingEarly care and education (ECE) centers in Nebraska. ParticipantsCooperative Extension coaches (n = 9), ECE administrators (n = 8), and teachers (n = 17) caring for children aged 3–5 years. InterventionThe EAT intervention (a 16-week, 7-lesson, evidence-based online responsive feeding ECE model) uses a multilevel improvement system of 5 implementation strategies. Early care and education administrators and teachers completed 1 lesson/wk followed by a coaching session. Main Outcome MeasuresThe Reach, Effectiveness, Adoption, Implementation, and Maintenance framework includes 5 evaluative dimensions. AnalysisThematic analysis. ResultsOverall, 77% of children aged 3-5 years (n = 216) participated from targeted Child and Adult Care Food Program ECEs (Reach). All perceived EAT improved children's nutritional and developmental outcomes and encouraged a positive mealtime environment (Effectiveness). Coaches found professional development incentives important, whereas administrators/teachers valued inservice hours (Adoption). Teachers reported successful implementation of responsive feeding, and administrators supported the teachers (Implementation). All reported they intended to continue using EAT, and administrators and teachers discussed incorporating EAT practices into the handbook/school policy (Maintenance). Conclusion and ImplicationsThe EAT was valued by all stakeholders for its perceived effectiveness to positively impact children's nutritional outcomes. Furthermore, stakeholders valued the provided incentives and multilevel design with coaching, ECE administrators, and teachers. Future research is needed on how to use Extension coaches in ECE interventions.

Maternal autonomy and childhood undernutrition: Analysis of 2018 Nigeria demographic and health survey.

Existing knowledge of how maternal autonomy relates to child undernutrition in Nigeria is few and limited to children under 24months old. Nothing is known about how it affects older children. Therefore, this study investigated whether mothers' household autonomy affects children 24-59months, as do children under 24months old. We used data from 2018 Nigerian Demographic and Health Survey, which is a nationally representative survey. Samples include 3502 and 5463 children under 24months and between 24 and 59months old, respectively. Three anthropometry indexes were used to determine child undernutrition: weight-for-height, height-for-age, and weight-for-age, which indicate wasting, stunting, and underweight, respectively. Three domains of maternal autonomy: decision-making, financial-control, and mobility, were operationalized using responses from mothers. Results from logistic regression analysis show that in unadjusted models, maternal decision-making autonomy and mobility were associated with undernutrition in both samples. After adding covariates, only associations between maternal decision-making autonomy and underweight in children 24-59months old retained statistical significance. Findings show that gendered social inequalities are linked to differences in child nutritional outcomes. Future studies could investigate how feeding practices mediate associations between maternal autonomy and childhood undernutrition.

A critical comparison of the Indian school food and nutrition guidelines with the WHO-nutrition friendly school initiative and the review of existing implementation scenario.

Background: The school-based food and nutrition guidelines approach has the potential to combat undernutrition, overnutrition and micronutrient deficiencies among children and adolescents and set the foundation for a healthy adult lifestyle. Aim: To critically compare the Nutrition Friendly School Initiative (NFSI) of the World Health Organization (WHO) with the Food Safety and Standards Authority of India (FSSAI) and the Indian Academy of Pediatrics (IAP) guidelines to gauge the strengths and limitations. Additionally, to summarize the existing studies on implementing school food and nutrition guidelines. Methods: Policy documents of the above guidelines were critically evaluated, and narrative analysis was conducted. An electronic search was conducted for full-text research articles published in the English language between January 2007 to September 2021 in Science Direct, PubMed, Web of Science, and SCOPUS databases. Results: Upon critical comparison of the three guidelines, it was found that the NFSI and FSSAI guidelines shared similarities in many components and the FSSAI guidelines, if implemented adequately, could improve the school food environment and combat the triple malnutrition burden in India. After screening the articles based on the eligibility criteria, 11 studies were included in the preparation of the review. Studies reported partial or inadequate implementation and poor compliance with the guidelines or approach. A few studies identified barriers to guideline implementation. Conclusion: Implementation of school food and nutrition guidelines could improve the nutritional outcomes in children and adolescents. To sustain the effective implementation, adequate resources and preparedness are essential in low-and middle-income countries, including India.

Grandi Byen—Integrated Responsive Parenting, Nutrition, and Hygiene for Child Growth and Development: Protocol for a Randomized Controlled Trial

Objectives Grandi Byen—to grow well in Haitian Creole—tests the effectiveness of a multicomponent intervention encompassing nutrition, responsive parenting, and WASH (water, sanitation and hygiene) during the complementary feeding period on child growth and neurobehavioral development.MethodsThis study is a three-arm, longitudinal randomized controlled trial. Mothers/caregiver and their infants (ages 6–8 months at baseline) living in Cap-Haitien, Haiti (N = 600 dyads) will be randomly and equally assigned into the following groups: 1) standard well-baby care (control); 2) nutrition intervention (one egg per day for 6 months); and 3) multicomponent Grandi Byen intervention (one egg per day for 6 months + 12-week psychoeducational intervention on responsive parenting, nutrition, and WASH practices).ResultsPrimary outcomes for this study are child growth (length-for-age-, weight-for-age-, and weight-for-length Z scores) and development (cognitive, language, motor, and social-emotional). Secondary outcomes that are hypothesized as mediators to the primary outcomes are child health (bone maturation, brain growth, diarrheal morbidity and allergies, dietary intake, nutrient biomarkers) and parent-specific outcomes (responsive parenting and parental mental health). Targeted genomics will also highlight potential interactions between host genetics, enteric pathogens, gut microbiota, and overall child development. Findings will demonstrate the reproducibility and feasibility of egg-based interventions, while testing their impact on reducing child stunting and suboptimal development. Additionally, the multicomponent intervention will demonstrate whether stimulating care and WASH education induces any incremental benefits on child nutrition and developmental outcomes.ConclusionsThis project shifts from the norm of single-component nutrition interventions (e.g., single nutrient supplements and other food-based interventions) in child health research. The Grandi Byen concept approaches child well-being holistically by addressing poor child growth and development through nutrition along with proximal environmental and psychosocial determinants of child development.Funding SourcesEunice Kennedy Shriver National Institute of Child Health and Development (NICHD).

Wasting, Stunting, and Anemia in Angolan Children after Deworming with Albendazole or a Test-and-Treat Approach for Intestinal Parasites: Binary Longitudinal Models with Temporal Structure in a Four-Arm Randomized Trial.

Undernutrition, anemia, and intestinal parasitic infections are public health problems in Angola, especially in pre-school children. We analyzed binary data from a longitudinal four-arm randomized parallel trial conducted in Bengo Province, northern Angola, over the course of two years, with seven follow-up assessments to explore the effects of four interventions (deworming and a test-and-treat approach for intestinal parasites, at both the individual and household levels) on wasting and stunting, and to understand their indirect benefits for anemia, malaria, diarrhea, and vomiting. A total of 121 children with intestinal parasitic infections received baseline treatment, and were allocated to the four arms (1:1:1:1). Using continuous outcome variables of height-for-age (HAZ) and weight-for-height (WHZ) statistical approaches did not reveal a clear benefit of any particular arm (Pathogens 2021, 10, 309). Next, HAZ and WHZ were transformed into binary variables of stunting and wasting, respectively, considering their mild-to-severe (Z-score < −1) and moderate-to-severe degrees (Z-score < −2). Original clinical data (on anemia, diarrhea, vomiting, and malaria) were also analyzed. From a binary longitudinal analysis with different dependence structures, using the R package bild, fitted models revealed the potential benefit of a test-and-treat approach at the individual level for wasting compared with annual albendazole at the individual level, especially considering mild-to-severe forms (ORadj = 0.27; p = 0.007). All arms showed similar effects on stunting, compared with annual albendazole, at a 5% significance level. Time and age at baseline presented favorable effects in the percentage of stunting using both severity degrees. Results showed a decreased chance of having anemia and diarrhea over time, although with no significant differences between arms. Data from longitudinal studies are essential to study the direct and indirect effects of interventions, such as deworming, and to explore additional approaches aiming at better understanding the temporal structure of nutrition and health outcomes in children.

Understanding Discrepancies in Nutritional Outcomes Among Under-Fives in Laos: A Mixed-Methods Study Using the Positive Deviance Approach.

Background:Stunting is one of the main contributing factors in the under-five mortality rate worldwide. In Laos, the prevalence of stunting remains high, particularly in mountainous rural areas. To prevent stunting, insight into positive deviant behaviors can help understand how people can cope or adapt in resource-poor settings.Objective:This study aims to analyze the practices and underlying factors that explain discrepancies in nutritional outcomes in children under the age of 5 in remote mountainous areas in Laos.Methods:This mixed-methods study included all children under the age of 5 living in 6 selected villages. Anthropometric measurements were taken, and a Z-score for stunting was calculated to select the positive and negative deviant children. To identify the causes of discrepancies in childhood stunting, household questionnaires, focus group discussions, observations, and individual interviews with family members and health workers were conducted.Results:Fifty-five percent of children were stunted. Inappropriate care and feeding practices were observed such as providing unbalanced diets and not attending health facilities. Positive deviant mothers were less likely to follow inappropriate practices, experienced less food insecurity, and had higher motivation and autonomy, which resulted in prioritizing their children’s health. An active role of fathers seemed to benefit positive practices within households.Conclusions:The combination of many different practices in which positive deviant families are doing slightly better was associated with in less stunting of children. Those practices are related to the household resources, such as access to food and social support; and the mother’s motivation, autonomy, and perspectives on child health.

Mediating role of social capital in the association between socioeconomic status and childcare practices in rural Malawi: a cross-sectional study

Inequality of opportunity in children's nutritional outcomes in China

Using pooled data from the 1991–2011 waves of the China Health and Nutrition Survey (CHNS), this paper proposes an empirical study on inequality of opportunity in child nutritional outcomes. Children's nutritional outcomes were measured using anthropometric indicators including underweight, stunting, wasting, overweight and obesity. We examine the role played by circumstances beyond the control of individuals—for instance, children's age, gender, hukou status, household size, birth order, family background, region and sanitation—in generating nutritional outcomes inequality among Chinese children aged 0–15. We find that the largest relative share of inequality of opportunity (IOP) in child nutritional outcomes in China is 11.49% (stunting) for the entire sample. Shapley-value decompositions reveal that region and family background are the dominant contributors to inequality of opportunity for most of the nutritional outcomes. IOP turns out to be largest for the 6–10 age cohort. Heterogeneity analysis further shows that disadvantaged groups, for instance, children living in the rural area of western China, face higher unequal opportunities for undernutrition. Conversely, children from urban area of the east show a higher inequality of opportunity in overnutrition. In addition, our counterfactual analysis indicates that if those rural children had migrated to cities, the IOP for the full sample would increase by more than 19%, implying greater attention should be paid to equalizing opportunity amid massive migration and urbanization in China in the years to come.
