Children's experiences during early childhood are critical for their cognitive and socio-emotional development, two key dimensions of human capital.However, children from low income backgrounds often grow up lacking stimulation and basic investments, leading to developmental deficits that are difficult, if not impossible, to reverse later in life without intervention.The existence of these deficits are a key driver of inequality and contribute to the intergenerational transmission of poverty.In this paper, we discuss the framework used in economics to model parental investments and early childhood development and use it as an organizing tool to review some of the empirical evidence on early childhood research.We then present results from various important early childhoods interventions with emphasis on developing countries.Bringing these elements together we draw conclusions on what we have learned and provide some directions for future research.
In this study, we analyse if in-utero exposure to Ramadan fasting period is negatively associated with child nutrition? The data for the analyses come from a retrospective assessment of 924,198 children from 103 demographic and health surveys (DHS) across 56 countries during the period 2003-2020. Considering the month-long Ramadan exposure as a natural experiment, we implement an intent-to-treat framework, comparing outcomes among individuals who were exposed to Ramadan at any time in-utero to those who were not exposed. Our findings do not show significant evidence to conclude that in-utero exposure to Ramadan fasting period is negatively associated with child nutrition. On the contrary, except for stunting in children who had in-utero exposure to Ramadan during the first trimester, among Muslims, we find slightly better nutritional outcomes among children exposed in-utero to Ramadan period. The better nutritional outcomes among children exposed in-utero can be attributed to high nutritious food intake and better hygienic practices during holy months of Ramadan compared to usual months. Our main results are robust to multiple robustness checks.
The foundations for successful child development are established in early childhood.Two main policy approaches for strengthening these foundations have been subsidized preschool programs and programs targeting the home environment.Our chapter reviews a large body of empirical work investigating whether these programs make a difference for children's development, and if so, how and under what conditions do they help, how cost-effective are they, and which programs are scalable.We start by reviewing studies that estimate how much of the variation in child outcomes can be explained by genetics versus environmental factors.These studies demonstrate that variation in environmental factors plays a key role in explaining individual life outcomes.This suggests that early childhood programs might play a significant role in helping children realize their potential in life.Nevertheless, our review of early childhood programs demonstrates that the evidence is mixed -some programs are successful in fostering lasting skill development, but many are not.We conclude that existing research on early childhood education falls short of sufficiently answering fundamental questions about what works for whom and why.A tighter link between theory, econometric methods and data is essential to compare and reconcile the mixed and sometimes conflicting empirical results across studies, and to understand when and why the impacts of home environment and pre-school interventions fadeout.
Stunting is the one factor that is responsible for the irretrievable damage to children's mental and physical health. Stunting imitates chronic undernutrition throughout the most extreme critical stages of growth and development of a child in their early life, and due to that stunted child does not completely develop and are too short for their age. Stunting is mainly linked with brain underdevelopment, along with lifelong damaging consequences, comprising weakened mental and learning capacity, deprived performance in school during childhood, and enhanced risks of nutrition linked to chronic long-lasting ailments, such as diabetes, hypertension, diabesity, and obesity in the future. In this review, the authors mainly summarize the latest studies related to chronic nutrition and how it is related to stunting. Optimal nutrition, particularly during pregnancy and the first 24 months of a child's life, is crucial in preventing stunting. Circadian rhythms play a significant role in maternal and fetal health, affecting outcomes such as premature birth and stunting. Maintaining a balanced diet, avoiding late-night carbohydrate-heavy meals during pregnancy, and promoting breastfeeding align with the body's biological clock, which can benefit newborns in various ways. Providing dedicated spaces for breastfeeding in public places is important to support infant health.

BACKGROUND: Maternal parity, which is usually measured as the number of children born to a mother, has a substantial impact on the social and environmental factors around children and their development. This paper estimates the Early Childhood Development Index (ECDI) of 3- and 4-year-old children in Bangladesh and examines the relationship between maternal parity and early childhood development. METHODS: The study analysed nationally representative data from the Bangladesh Multiple Indicator Cluster Survey 2019. The dataset had 9453 children aged from 36 to 59 months. The ECDI was computed following the UNICEF's approach involving psychometric computation of four domains of development: physical, literacy-numeracy, learning and social-emotional. Since the dataset has a hierarchical structure, we used multilevel logistic regression. RESULTS: A quarter (25%) of the children were not on track in their early childhood development. Seventy-one percent were not developmentally on track in the literacy-numeracy domain, 27% were not in the social-emotional and smaller percentages were not in learning (9%) and physical (1%) domains. There was a significant negative association between maternal parity and ECDI (adjusted odds ratio [AOR] 0.95; 95% CI: 0.91-0.99). Attendance at early childhood education programmes was significantly associated with early childhood development (AOR 1.73; 95% CI: 1.47-2.03). Also, female children, those who were not stunted, located in rural areas, received parental stimulation activities, lived in relatively wealthy households or had mothers who had received secondary or further education were more likely than others to be on track of early childhood development. CONCLUSIONS: Early childhood development is negatively correlated with maternal parity. The literacy-numeracy domain constitutes the major developmental delay. Programmes for parental awareness should be widely expanded.
One of the problems of growth and development in children is stunting, the cause of stunting is not consuming balanced nutritious food so that it greatly affects the process of growth and development of children under five.The specific objective to be achieved in this study is to analyze the effectiveness of providing balanced nutrition to stunted children.The research design used a quasiexperimental research design with one group pre and post-test design.The sample used is a random sampling of 45 children under five.Data collection tools with observation sheets and anthropometric tools.From the results of the Wilcoxon statistical test on the weight variable, the significant number or probability value (0.008) is much lower, the standard is significantly lower than 0.05 or (p < ), then H0 is rejected and H1 is accepted, which means that there is an effect of balanced nutrition on recovery.nutritional status of stunting children in the work area of the Tangerang District Health nutritional status of stunting children in the work area of the Tangerang District Health
In this paper we describe ways to measure variables of interest when evaluating the implementation of a program to improve early childhood development (ECD). The variables apply to programs delivered to parents in group sessions and home or clinic visits, as well as in early group care for children. Measurements for four categories of variables are included: training and assessment of delivery agents and supervisors; program features such as quality of delivery, reach, and dosage; recipients' acceptance and enactment; and stakeholders' engagement. Quantitative and qualitative methods are described, along with when measures might be taken throughout the processes of planning, preparing, and implementing. A few standard measures are available, along with others that researchers can select and modify according to their goals. Descriptions of measures include who might collect the information, from whom, and when, along with how information might be analyzed and findings used. By converging on a set of common methods to measure implementation variables, investigators can work toward improving programs, identifying gaps that impede the scalability and sustainability of programs, and, over time, ascertain program features that lead to successful outcomes.
BACKGROUND: Child stunting and linear growth faltering have declined over the past few decades and several countries have made exemplary progress. OBJECTIVES: To synthesize findings from mixed methods studies of exemplar countries to provide guidance on how to accelerate reduction in child stunting. METHODS: We did a qualitative and quantitative synthesis of findings from existing literature and 5 exemplar country studies (Nepal, Ethiopia, Peru, Kyrgyz Republic, Senegal). Methodology included 4 broad research activities: 1) a series of descriptive analyses of cross-sectional data from demographic and health surveys and multiple indicator cluster surveys; 2) multivariable analysis of quantitative drivers of change in linear growth; 3) interviews and focus groups with national experts and community stakeholders and mothers; and 4) a review of policy and program evolution related to nutrition. RESULTS: Several countries have dramatically reduced child stunting prevalence, with or without closing geographical, economic, and other population inequalities. Countries made progress through interventions from within and outside the health sector, and despite significant heterogeneity and differences in context, contributions were comparable from health and nutrition sectors (40% of change) and other sectors (50%), previously called nutrition-specific and -sensitive strategies. Improvements in maternal education, maternal nutrition, maternal and newborn care, and reductions in fertility/reduced interpregnancy intervals were strong contributors to change. A roadmap to reducing child stunting at scale includes several steps related to diagnostics, stakeholder consultations, and implementing direct and indirect nutrition interventions related to the health sector and nonhealth sector . CONCLUSIONS: Our results show that child stunting reduction is possible even in diverse and challenging contexts. We propose that our framework of organizing nutrition interventions as direct/indirect and inside/outside the health sector should be considered when mapping causal pathways of child stunting and planning interventions and strategies to accelerate stunting reduction to achieve the 2030 Sustainable Development Goals.

Background The urban environment presents significant health challenges for children, such as discouraging physical exercise and increasing exposure to air pollution, excessive noise and higher temperatures. Reducing exposures to these negative environmental factors can have great benefits on a child's well-being and lower their risk of developing chronic diseases later in life. There is increasing evidence that suggests that the presence of urban green space can offer benefits to human health and well-being. While studies have reported the impact green space exposure has on the individual health outcomes of children, few have paid attention to the link between green space and the child's development. This review aims to synthesise the evidence of the effect green space exposure has on early childhood development. Objectives To explore the relationship between green space and early childhood development. Methods An online search was conducted using pre-identified keywords related to green space and early childhood development using search engines such as PubMed, MEDLINE, Web of Science, MeSH and PsycINFO. Peer-reviewed papers published in the past 10 years were included in this review. Papers were selected, extracted, analysed and interpreted based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Results Fifty-one papers were identified, of which 28 were excluded due to duplications or irrelevance, yielding a total of 23 papers to be reviewed. Articles were categorised based on reported outcomes: perinatal health, physical health, psychological health and respiratory health. An increase in green space during pregnancy was associated with increased birth weight and a decreased risk for low birth weight (LBW). Further, higher greenness exposure during childhood was associated with increased levels of physical activity and a lower risk of obesity and neurodevelopmental issues such as inattentiveness. While green space exposure was negatively associated with wheezing and bronchitis in some cohorts, certain plant species increase asthmatic symptoms during childhood, indicating that plant species type is an important determinant. Conclusion The extant literature on green space exposure and early childhood development is small. Regardless, the existing research provides promising insights into the benefits of green space exposure on children's health and well-being in an ever-increasing urban world. Further research is needed on the causal relationships between both quantity and quality of green space to early childhood development.

In many developing countries, supermarkets are spreading rapidly, complementing and partly replacing traditional food markets and grocery stores. Changing retail environments can affect consumer diets and nutritional outcomes. Previous research suggested that supermarkets may contribute to rising rates of obesity. However, most existing research looked at adult populations. Here, we analyze effects of supermarkets on child nutrition with panel data from urban Kenya. Buying food in supermarkets increases child height-for-age, weight-for-age, and weight-for-height Z-scores. The effects on child height are larger than the effects on weight, which is a welcome finding because child stunting (low height-for-age) remains a major nutritional problem that is declining more slowly than child underweight. Supermarkets do not seem to be a driver of childhood obesity in this setting. The positive effects of supermarkets on child nutrition are channeled through improvements in food variety and dietary diversity.
