Investing in the foundation of sustainable development: pathways to scale up for early childhood development

Co-Occurrence of Stunting and Off-Track Early Child Development in Low- and Middle-Income Countries

Importance

Although children across low- and middle-income countries (LMICs) are increasingly surviving, many are not fully thriving. Both stunting and off-track early child development (ECD) hinder children's potential to thrive.

Objectives

To estimate the global prevalence of the co-occurrence of stunting and off-track ECD and explore its association with nurturing care and sociodemographic factors.

Design, Setting, and Participants

This cross-sectional study pooled data from the most recent Demographic and Health Surveys and Multiple Indicator Cluster Surveys (2010-2020) on 173 416 children aged 36-59 months in 41 LMICs. Statistical analysis was conducted from February to December 2024.

Exposure

Risk factors pertaining to inadequate nurturing care, low socioeconomic status, and other sociodemographic characteristics.

Main Outcomes and Measures

Children were classified into 4 groups with respect to thriving: children who were stunted only (height-for-age z score <-2 SD), off-track ECD only (measured using the Early Childhood Development Index), both stunted and off-track ECD (co-occurrence), or neither.

Results

In the pooled sample of 173 416 children, the mean (SD) child age was 47.1 (6.8) months, and 88 242 (50.9%) were boys. Approximately 1 in 6 children (17.0% [95% CI, 16.8%-17.2%]) were both stunted and had off-track ECD, 17.1% (95% CI, 16.9%-17.3%) were stunted only, 27.8% (95% CI, 27.6%-28.0%) had off-track ECD only, and 38.1% (95% CI, 37.9%-38.4%) were neither stunted nor had off-track ECD. Socioeconomic gradients were observed, with more co-occurrence in lower-income countries (18.2% [95% CI, 17.9%-18.6%]), poorer households (22.1% [95% CI, 21.7%-22.5%] for poorest wealth quintile), mothers with lower educational levels (20.8% [95% CI, 20.6%-21.0%] for primary education or less), and rural settings (19.3% [95% CI, 19.1%-19.6%]). Various indicators of inadequate nurturing care along with low socioeconomic status were associated with co-occurrence. The top 5 factors associated with co-occurrence were poorest wealth quintile (adjusted odds ratio [AOR], 2.75; 95% CI, 2.53-2.99), no early childhood education (AOR, 2.22; 95% CI, 2.10-2.34), low maternal educational level (AOR, 1.44; 95% CI, 1.37-1.51), no toys at home (AOR, 1.43; 95% CI, 1.35-1.51), and diarrhea (AOR, 1.38; 95% CI, 1.31-1.45). The associations of poor household wealth, no birth registration, and no early childhood education with co-occurrence were significantly larger than their associations with stunting only or off-track ECD only.

Conclusions and Relevance

This cross-sectional study of young children in LMICs suggests that a significant proportion were both stunted and had off-track ECD. These findings underscore the need for multisectoral interventions that holistically target nutrition, health, and ECD risks to ensure that all children globally can thrive, especially those facing the double burden of stunting and off-track ECD.

Effect of a youth-led early childhood care and education programme on children's development and learning in rural Sindh, Pakistan (LEAPS): a stepped-wedge cluster-randomised implementation trial

BACKGROUND

In low-income and middle-income countries, an estimated 181·9 million (74·6%) preschool-aged children do not receive adequate nurturing care in health, nutrition, protection, learning, and responsive care, thus jeopardising their healthy development across the life course. Working alongside the health sector, multisectoral actions including social protection and education are necessary to achieve child health and development outcomes. Innovations are needed to expand access to high-quality early childhood care and education (ECCE) for young children and opportunities for youth development. Youth Leaders for Early Childhood Assuring Children are Prepared for School (LEAPS) is a two-generation programme that trains female youth aged 18-24 years to deliver ECCE. We evaluated the effectiveness of LEAPS to improve children's school readiness when delivered at scale in rural Pakistan.

METHODS

We implemented a stepped-wedge cluster-randomised trial with three steps from Dec 3, 2018, to June 30, 2021. 99 villages (clusters) in four districts in rural Sindh, Pakistan, were randomly assigned (1:1:1) to introduce LEAPS across three steps. Eligible clusters were those that had a feeder primary school run by the National Commission for Human Development, a department of the Ministry of Federal Education and Professional Training; were safe; had space for a LEAPS preschool; could identify a female youth to deliver the ECCE service; and had not previously participated in the pilot study. Government partners trained female youth, aged 18-24 years, to provide community-based ECCE, enrolling up to 20 children, aged 3·5-5·0 years, per class. Population-based cross-sectional surveys were conducted at baseline and after each step for children who were eligible if they resided in the cluster, were aged 4·5-5·5 years at the time of the survey, and without any severe clinical health conditions or disability. The primary outcome was children's school readiness using the International Development and Early Learning Assessment (IDELA) composite score comprising emergent numeracy, emergent literacy, socio-emotional development, and motor skills. An intention-to-treat analysis was conducted, using linear mixed models accounting for clustering and the stepped-wedge design. The trial is registered with ClinicalTrials.gov (NCT03764436).

FINDINGS

LEAPS was implemented in 91 of 99 villages. In eight clusters, a LEAPS preschool could not be set up. For the intervention programme, the average enrolment of children in a LEAPS preschool was 19 (SD 3, range 12-20). A total of 3858 children (n=3852 with complete IDELA data) were assessed across the four survey rounds conducted between Jan 1, 2019, and March 31, 2021. LEAPS increased school readiness (standardised mean difference: 0·30 [95% CI 0·20-0·40]; p<0·0001) as compared with the control condition.

INTERPRETATION

LEAPS offers a scalable solution to expand access to high-quality ECCE and promote children's school readiness while providing employment for female youth in rural Pakistan and settings with similarly low ECCE participation.

Factors associated with early childhood development: results from the Brazilian National Survey on Child Nutrition (ENANI-2019)

Introduction

The full achievement of early childhood development (ECD) is a human right and adhering to the nurturing care framework may facilitate it.

Objective

To evaluate the association between distal and proximal variables and developmental quotient (DQ).

Methods

Data from 14 159 children <5 years were evaluated in the Brazilian National Survey on Child Nutrition. The Survey of Well-being of Young Children-Brazilian version milestones questionnaire was used to evaluate ECD. The developmental age was estimated using the graded response models. DQ was calculated by dividing developmental age by chronological age. The expected age milestones are attained when DQ=1. DQ predictors were defined considering distal and proximal levels/variables using a multiple linear regression model and a hierarchical approach.

Results

The DQ mean was significantly lower among children aged 36-59 months (0.91 (0.88 to 0.93)), boys (1.03 (1.01 to 1.06)) and those from the North region (0.98 (0.93 to 1.04)) compared with children aged 1-35 months (1.18 (1.15 to 1.22)), girls (1.11 (1.08 to 1.13)) and from the Southeast region (1.11 (1.07 to 1.16)). For children aged 1-35 months, DQ was inversely associated with emergency C-section (β=-0.08; p<0.01), consumption of ultra-processed food (β=-0.33; p<0.01), and positively associated with attendance at daycare/school (private: β=0.09; p=0.02 and No: β=0.12; p<0.01). For children aged 36-59 months, attendance to private daycare/school (β=0.08; p<0.01) was positively associated with DQ, and small for gestational age at birth (β=-0.05; p=0.01) and access to public health services (no-primary care) (β=-0.07; p<0.01) were inversely associated with DQ.

Conclusions

Adverse health, nutrition and learning factors predicted the ECD, demonstrating an inequitable environment for Brazilian children. These findings indicate a need for public policies to ensure social and health equity in early childhood.

Developmental delay and associated factors among HIV-infected under-five children in public health facilities, Southern Ethiopia

Delays in development that occur during early childhood can have long-lasting consequences, potentially leading to poor academic achievement. Research has shown that the human immunodeficiency virus can have neurotropic effects, which may impact the development of the brain in infected children. However, there is a scarcity of evidence regarding developmental delays among children with human immunodeficiency virus in the study area. This study aimed to determine the prevalence of developmental delay and associated factors among children with the human immunodeficiency virus in southern Ethiopia. A cross-sectional study was undertaken among 422 children aged below five during October 30 to December 30, 2021, who acquired the human immunodeficiency virus at public hospitals. A pretested tool anthropometric measurements were utilized. To examine developmental delay, the age and stage questionnaires (version 3) were used. Descriptive statistics were performed. Bivariable and multivariable binary logistic regression models were fitted to identify potential factors associated with delays in child development. The analysis was performed using STATA version 14.2. Adjusted odds ratios with 95% confidence intervals and variables with p-values less than 0.05 were considered to be significantly associated with global developmental delay. A total of 413 under-five children with human immune virus participated, with a 97.9% response rate. Of all children, 222 (53.75%) were male, and the mean age of children was 3.5 ± 1 (± SD) years. Overall global developmental delay was 41.89% [95% CI 37-47%]. Maternal age 35 and older [AOR 2.2; 95% CI (1.11-4.3)], maternal educational status [AOR 0.47; 95% CI (0.23-0.96)], higher birth order [AOR 3; 95% CI (1.5-4)], and stunting [AOR 2.2; 95% CI (1.4-3.42)] were significant factors associated with global developmental delay. Half of the children examined demonstrated delayed development across domains. The global developmental delay constitutes a significant public health concern, underscoring the necessity for early detection initiatives including developmental screening, diagnostic evaluations, and therapeutic interventions. We found significant associations between the developmental status of the children and the maternal age, educational level of mothers, higher birth order, and stunting of under-five children. Policies should aim to enhance mother and child health services, expand access to early intervention programs, and incorporate developmental surveillance into routine pediatric care. Additional research may be necessary to elucidate the underlying causes of the high prevalence of Global developmental delay, evaluate the efficacy of current interventions, and investigate innovative approaches to mitigate developmental delays.

Blueprint for Enhancing Implementation Quality of Criança Feliz Program in Brazil: A Combined Program Impact Pathways-ERIC Approach

Brazil's Criança Feliz Program is one of the largest early childhood development home-visiting programs globally. After seven years of scaling up, implementation barriers across diverse municipality settings prevented the program from achieving the intended impact on parenting skills and child development. We conducted a program impact pathway analysis to generate a blueprint to enhance implementation quality by (1) identifying the critical quality control points that need to be monitored throughout the scaling up and (2) specifying implementation strategies for enhancing implementation quality. The program impact pathway analysis consisted of inductive and deductive coding of pre-existing retrospective (e.g. reports, and codebooks from in-depth interviews) and workshop with national team to identify the critical quality control points and corresponding implementation barriers and facilitators. The Expert Recommendations for Implementation Change taxonomy was used to specify implementation strategies facilitating the scaling up or opportunities to address barriers across critical quality control points. We identified seven critical quality control points: hiring municipal workforce; staff training; home visits; complementary multisectoral actions; municipal supervision; technical assistance and monitoring; and funding. Implementation strategies facilitating the scale-up were "providing assistance" and "supporting teams;" opportunities for enhancing implementation quality were "financial strategies" and "evaluative and iterative strategies." Our analysis identified seven critical quality control points necessary to achieve the intended implementation and program outcomes. The combined use of the program impact pathway and the Expert Recommendations for Implementation Change taxonomy generated a meaningful blueprint of implementation strategies to enhance implementation quality, which may support the sustainability of a large-scale program.

Division of childcare policy actors under health-oriented goals: thematic analysis of China's policy texts from the social constructionist perspective

Background

Ensuring child health, as a key objective of global childcare policies, requires coordinated efforts between the government, social organizations and communities, institutions, and families. Despite China's progress in comprehensive childcare policy development, rapid economic growth, and urbanization, challenges persist, such as urban-rural disparities and unequal resource distribution, highlighting the need for effective collaboration between policy actors.

Methods

To collect textual data, this study searched for prefectural-level childcare policy texts issued since 2019 on government websites and legal databases, ultimately identifying 224 documents for analysis. This study reviewed the literature on the impact of childcare policies on child health and identified the enhancement of childcare quality as a current research focus. This study then conducted a content analysis using Nvivo12 Plus software and coded and analyzed the childcare policy content. Finally, it applied social construction theory to interpret the policy documents.

Results

Childcare policies were centered around child health and formed a responsibility and accountability framework between the government, social organizations and communities, institutions, and families, whose action shares accounted for 38.9, 22.89, 29.05, and 9.16%, respectively. The development of childcare institutions was a key aspect of the defamilialization trend. Compared to other policy actors, institutions played a larger role in child health policy aspects such as safety management (12.97%), health and hygiene (8.56%), and scientific parenting (10.93%).

Conclusion

Within China's health-oriented framework, the refamilialization and defamilialization processes coexist in terms of childcare policies, and limited community-based childcare resources extend beyond the family. The participation of diverse policy actors in China's childcare system is expected to persist, underscoring the increased need to enhance the policy actors' negotiation skills and bolster community-based childcare services in the future.

Associations between sociodemographic exposures, growth and development during infancy with development at the age of eight years among children: Analysis of a maternal education trial in rural Uganda

Background

Links between early life exposures and child development later in life are not sufficiently explored in low- and middle-income countries. We studied associations between sociodemographic variables, growth and development at six to eight months with developmental outcomes at eight years.

Methods

We used data from a maternal education trial which included 511 mother-infant pairs at children's age of six to eight months (baseline). In this follow-up study, data from 361 mother-child pairs were available. Questionnaires were used to collect sociodemographic variables. Growth (anthropometry) was measured by study personnel and converted to z-scores according to the World Health Organization (WHO) growth reference. Child development (cognitive, motor and language) at baseline was assessed using Bayley Scales of Infant and Todler Development, third edition (BSID-III). Development at eight years was measured using two neuropsychological tools: Kaufman Assessment Battery for Children Second Edition (KABC-II) and Test of Variables of Attention (TOVA).

Results

Higher weight-for-age z-scores (adjusted odds ratio (aOR) = 0.74; 95% confidence interval (CI) = 0.53, 0.98; P = 0.04), better maternal education (aOR = 0.86; 95% CI = 0.78, 0.96; P = 0.03). and better household head education (aOR = 0.86; 95% CI = 0.78, 0.96; P = 0.03) at six to eight months of age were associated with lower odds of scoring below average on KABC-II categorical scores at eight years of age. Motor composite scores and maternal parity at six to eight months of age were positively associated with auditory and visual TOVA scores (all P-values <0.05) at eight years. Cognitive composite scores at six to eight months of age were positively associated with visual TOVA scores (P < 0.05). In contrast, weight-for-length z-scores and household head age were negatively associated with both auditory and visual TOVA scores (P < 0.05). Being a female child was associated with lower auditory and visual TOVA scores (P < 0.05).

Conclusions

At six to eight months of age, growth and development, gender, maternal education and parity, and household head age and education were associated with child development at eight years. Interventions emphasising improved growth and development in infancy, as well as parental educational attainment, may improve long-term developmental outcomes.

Emergence and evolution of developmental resilience science over half a century

This reflection on the history and future of developmental resilience science (DRS) highlights its co-emergence with developmental psychopathology (DP), as well as the roles of this journal and its founding editor, Dante Cicchetti, in the evolution of these intertwined domains of scholarship. A remarkable constellation of scholars at the University of Minnesota shaped the course of both conceptual frameworks and their dissemination. I describe fundamental assumptions common to DP and DRS frameworks that reflect their common roots and the pervasive influence of systems theory on developmental science. I describe four waves of DRS and key principles of DRS at the present time. In conclusion, I consider the possibility that a fifth wave of DRS is emerging with a focus on understanding patterns of multisystem, multilevel processes of resilience and their implications for interventions in the context of interacting, interdependent, and complex adaptive systems. I close this commentary with questions for future research and a hopeful outlook on the future of human resilience.

Preventing malnutrition within the first 1000 days of life in under-resourced communities: An integrative literature review

This integrative review aimed to summarise existing best evidence practice for preventing malnutrition within the First 1000 Days of Life in under-resourced communities. BioMed Central, EBSCOHOST (Academic Search Complete, CINAHL and MEDLINE), Cochrane Library, JSTOR, Science Direct and Scopus were searched as well as Google Scholar and relevant websites for grey literature. Most recent versions of strategies, guidelines, interventions and policies; published in English, focussing on preventing malnutrition in pregnant women and in children less than 2 years old in under-resourced communities, from January 2015 to November 2021 were searched for. Initial searches yielded 119 citations of which 19 studies met inclusion criteria. Johns Hopkins Nursing Evidenced-Based Practice Evidence Rating Scales for appraising research evidence and non-research evidence were used. Extracted data were synthesised using thematic data analysis. Five themes were derived from extracted data: 1. Improving social determinants of health using a multisector approach; 2. Enhancing infant and toddler feeding; 3. Managing healthy nutrition and lifestyle choices in pregnancy; 4. Improving personal and environmental health practices; and 5. Reducing low-birthweight incidence. Further exploration regarding preventing malnutrition in the First 1000 Days in under-resourced communities is required using high-quality studies. Systematic review registration number: H18-HEA-NUR-001 (Nelson Mandela University).

The next 1000 days: building on early investments for the health and development of young children

Following the first 1000 days of life that span from conception to two years of age, the next 1000 days of a child's life from 2-5 years of age offer a window of opportunity to promote nurturing and caring environments, establish healthy behaviours, and build on early gains to sustain or improve trajectories of healthy development. This Series paper, the first of a two-paper Series on early childhood development and the next 1000 days, focuses on the transition to the next 1000 days of the life course, describes why this developmental period matters, identifies the environments of care, risks, and protective factors that shape children's development, estimates the number of children who receive adequate nurturing care, and examines whether current interventions are meeting children's needs. Paper 2 focuses on the cost of inaction and the implications of not investing in the next 1000 days. In low-income and middle-income countries (LMICs), only 62 million children aged 3 and 4 years (25·4%) currently receive adequate nurturing care during the next 1000 days, leaving 181·9 million children exposed to risks that jeopardise their healthy development. Inputs across nurturing care dimensions of health, nutrition, protection, responsive care, and learning vary substantially across countries. In LMICs, although 86·2% of children have a healthy weight in this period, less than one in three children have access to developmental stimulation or are protected from physical punishment, and only 38·8% have access to early childhood care and education services. Intervention research in LMICs in the next 1000 days is scarce. The continuity of developmentally appropriate nurturing care, coordination across health, education, and protection sectors, and the implementation of interventions to support caregivers and improve the quality of education and care remain top priorities in this period. These sectors play key roles in promoting quality early care and education for this age group, which will help maximise developmental potential and opportunities of children globally and help progress towards the achievement of the Sustainable Development Goals.

The cost of not investing in the next 1000 days: implications for policy and practice

Building on the evidence from the first paper in this Series highlighting the fundamental importance of healthy and nurturing environments for children's growth and development in the next 1000 days (ages 2-5 years), this paper summarises the benefits and costs of key strategies to support children's development in this age range. The next 1000 days build on the family-based and health-sector based interventions provided in the first 1000 days and require broader multisectoral programming. Interventions that have been shown to be particularly effective in this age range are the provision of early childhood care and education (ECCE), parenting interventions, and cash transfers. We show that a minimum package of 1 year of ECCE for all children would cost on average less than 0·15% of low-income and middle-income countries' current gross domestic product. The societal cost of not implementing this package at a national and global level (ie, the cost of inaction) is large, with an estimated forgone benefit of 8-19 times the cost of investing in ECCE. We discuss implications of the overall evidence presented in this Series for policy and practice, highlighting the potential of ECCE programming in the next 1000 days as an intervention itself, as well as a platform to deliver developmental screening, growth monitoring, and additional locally required interventions. Providing nurturing care during this period is crucial for maintaining and further boosting children's progress in the first 1000 days, and to allow children to reach optimal developmental trajectories from a socioecological life-course perspective.

Global development assistance for early childhood care and education in 134 low- and middle-income countries, 2007-2021

INTRODUCTION

Low- and middle-income countries (LMICs) often dedicate limited domestic funds to expand quality early childhood care and education (ECCE), making complementary international donor support potentially important. However, research on the allocation of international development assistance for ECCE has been limited.

METHODS

We analysed data from the Creditor Reporting System on aid projects to assess global development assistance for ECCE in 134 LMICs from 2007 to 2021. By employing keyword-searching and funding-allocation methods, we derived two estimates of ECCE aid: a lower-bound estimate comprising projects primarily focusing on ECCE and an upper-bound estimate comprising projects with both primary and partial ECCE focus, as well as those that could benefit ECCE but did not include ECCE keywords. We also assessed aid directed to conflict-affected countries and to ECCE projects integrating COVID-19-related activities.

RESULTS

Between 2007 and 2021, the lower-bound ECCE aid totaled US$3646 million, comprising 1.7% of the total US$213 279 million allocated to education. The World Bank led in ECCE aid, contributing US$1944 million (53.3% out of total ECCE aid). Low-income countries received less ECCE aid per child before 2016, then started to catch up but experienced a decrease from US$0.8 (2020) per child to US$0.6 (2021) per child. Funding for ECCE projects with COVID-19 activities decreased from a total of US$50 million in 2020 to US$37 million in 2021, representing 11.4% and 6.6% of annual total ECCE aid, respectively. Over 15 years, conflict-affected countries received an average of US$0.3 per child, a quarter of the aid received by non-conflict-affected countries (US$1.2 per child).

CONCLUSION

Although ECCE aid increased significantly between 2007 and 2021, its proportion of total educational aid fell short of UNICEF's suggested 10% minimum. Recommendations include increasing the share of ECCE aid in total educational aid, increasing aid to low-income and conflict-affected countries, and investing more in preparing ECCE programmes for future global crises.

Refugee mothers' mental health in Denmark: possibilities and limits of home visiting programs

PURPOSE

To explore the experiences of refugee mothers and community health nurses participating in a nurse home visiting program in Denmark, focusing on the program's effects on the psychosocial well-being of refugee mothers during the transition to motherhood.

METHODS

The nurse home visiting program was an add-on the public care offered to all families, with extra training of the community health nurses and more time to engage with the families with immigrant and refugee backgrounds. Community health nurses (12) and participating women (9) participated in qualitative interviews between September and December 2020, following the program's conclusion.

RESULTS

Utilizing the Resource-Based Model of refugee adaptation as a theoretical framework, we identified four main themes: (i) negotiating parenting norms and gaining confidence through parenting resources; (ii) finding emotional support to cope with integration pressures; (iii) expanding social resources, (iv) building bridges with welfare state services. These themes captured the resources gained by mothers through the home visiting program, positively influencing their psychosocial well-being, while also acknowledging the impact of the socio-political context on community health nurses' work and mothers' daily lives.

CONCLUSION

Findings offer insights about the potential and limitations of tailored nurse home visiting programs for refugee families, emphasizing the positive impact on mental health. However, challenges such as assimilation pressures, unwelcoming immigration policies, and discrimination may hinder program effectiveness.

Interplay of paternal caregiving and screen use habits on early childhood development and children's tantrums

BACKGROUND

This study aims to examine the association for paternal care and father-child screen use with early childhood development and children's temper tantrums.

METHOD

Study file included questions about paternal characteristics, child care, father-child screen habits, and utilized the UNICEF Early Childhood Development Index (ECDI). Factors influencing ECDI-on-track status and children's responses when screen use was restricted were investigated with Chi-square test and multiple logistic regression.

RESULTS

The study included 464 fathers having children aged 3-4 years. The findings showed that 89.7% of the children were on track in three out of the four ECDI subgroups. When screen use was restricted, 55.6% of the children engaged in another activity, while 44.4% reacted by crying. Multiple logistic regression analysis revealed that the father's education level, the child's age and gender, the starting age for screen usage, the child's reaction to screen restriction, and having three or more books were associated with ECDI. Furthermore, the child's reaction to screen restriction was related to the child's and father's screen time, the presence of three or more books, the adequacy of care, and being on track in the literacy-numeracy ECDI subgroup.

CONCLUSION

Screen usage habits significantly impact early childhood development and children's reactions to screen restrictions. These findings underscore the importance of educating fathers about the effects of their own and their child's media habits, the quality of fatherly caregiving, and the presence of books in fostering positive child development.

Vision Screening and Detection of Ocular Abnormalities in School Children by Teachers in Jordan

Purpose

To evaluate the accuracy of vision screening and detection of ocular abnormalities conducted by teachers in school children in Jordan compared with vision testing by optometrists and ocular disease identification by ophthalmologists.

Methods

A non-random, purposive sampling strategy where 6-year-old and 15-year-old school children from three schools in Amman, Jordan were included. Twenty-two teachers were trained to conduct visual acuity screening using the 0.2 logMAR line of the distance visual acuity (DVA) chart at 10 feet and near visual acuity (NVA) chart at 16 inches, in addition to detecting ocular abnormalities. An optometrist assessed the visual acuity and conducted objective and subjective refraction, while an ophthalmologist examined the ocular health of all children.

Results

A total of 542 children (51% female) were included in the study, of which 47% were 6 years old and 53% were 15 years old. Teacher screening had sensitivities of 76.92% for DVA, 68% for NVA, and 37.50% for abnormality detection. The specificities of DVA, NVA, and ocular abnormalities were 98.22%, 98.48%, and 99.24%, respectively. The positive predictive value for DVA, NVA, and ocular abnormalities were 83.33%, 99.00%, and 60%, respectively. The negative predictive value for each procedure was 98.22% for DVA, 98.48% for NVA, and 98.12% for ocular abnormalities.

Conclusion

Teachers were able to conduct vision screening with a high level of accuracy compared to the gold standard of testing by optometrists, which would be useful for the early detection and referral of refractive errors in school children. However, they were unable to detect ocular abnormalities compared with the gold standard for disease identification by ophthalmologists. Further training and monitoring, or different training approaches should be implemented to enable teachers to identify ocular abnormalities at acceptable levels.

Longitudinal analysis of growth and nutritional disparities across socio-demographics from early childhood to adolescence: Findings from the Indian cohort of the Young Lives Survey

OBJECTIVES

Previous studies generally used cross-sectional data and focused on under-five children to assess the risk factors for malnutrition among Indian children. Some recent studies have reported that recovery from or faltering in malnutrition is possible after five years of age, but socio-demographic subgroup disparities have not been explored. This study aims to find the longitudinal disparity in height-for-age Z-scores (HAZ) and body-mass-index-for-age Z-scores (BMIAZ scores) across various sub-groups of a cohort from childhood to adolescence.

METHODS

This study used a cohort from the Young Lives Survey, which followed children aged of 1-15 years between 2002 and 2016-17 in the states of Andhra Pradesh and Telangana, India. Mixed-effect models were applied to find the main, time, and interaction effects of HAZ scores and BMIAZ scores. In addition, an extended Kitagawa-Oaxaca-Blinder decomposition approach to assess group-based differences over time was used.

RESULTS

The cross-sectional prevalence of stunting reduced across all subgroups, while thinness rose during the same period. The interactions of child sex, mother's education, place of residence, wealth index, and antenatal care with time were statistically significant at p <0.05. The gender disparity in adjusted HAZ score  decreased from 0.214 units at 1 year to 0.011 units at 15 years, whereas BMIAZ score differential increased from 0.106 to 0.538 units over same timeframe. Disparities in scores were also observed across rural-urban, maternal education, social group, religion, socioeconomic status, maternal age at birth, antenatal care, and premature birth status.

CONCLUSION

The study sheds light on the nuanced dynamics of paediatric growth, emphasising the importance of longitudinal approaches in understanding and addressing the health disparities across different stages of childhood and adolescence.

Perinatal and early life risk factors of adverse early childhood developmental outcomes: Protocol for systematic review using socioecological model

BACKGROUND

Adverse early childhood developmental outcomes impact later schooling and adulthood life courses. However, there needs to be more comprehensive evidence on the effect of various perinatal and early life risk exposures. Hence, we aimed to systematically identify the various perinatal and early childhood risk factors using a socioecological model to inform appropriate prevention strategies.

METHOD

The systematic review will adhere to the 2020 PRISMA guidelines. The protocol was registered in PROSPERO with a registration number of CRD42023447352. We will systematically search for articles on adverse early childhood developmental outcomes, which include physical, cognitive, language and communication and social-emotional development from main databases, such as EMBASE, Medline, Global Health, PsycINFO, CINAHL and Web of Science Core Collection, dating from 2000. We will use Population, Exposure, Comparator, Outcome and Study Design (PECOS) criteria to select eligible studies for our review: 1) Population includes children in early childhood age (i.e., up to eight years) undergoing developmental assessments. 2) Exposure: various perinatal and early life risk factors. 3) Comparators: Children with no or low levels of exposure to the risk factors. 4) Outcome: adverse early childhood developmental outcome. 5) Study design: all observational studies that report the prevalence or incidence of adverse early childhood developmental outcomes and associated risk factors published since 2000. There will be no restriction based on country of origin or geographical location except language (only published in English). Textual and narrative synthesis using the socioecological model will be used to synthesise the data.

Integrating early child development into an existing health and nutrition program: evidence from a cluster-randomized controlled trial

INTRODUCTION

In low-resource settings, introducing child health programs into community services may compete for caregiver time. We analyzed the impact of a new early childhood development (ECD) program in rural Madagascar on family attendance at other health services and of adding at-home play materials on program attendance.

METHODS

We randomized 75 communities where community health workers (CHWs) implement an existing child health and nutrition program (Projet d'Amélioration des Résultats Nutritionnels or PARN), the status quo. We offered two 6-month cycles of 12 ECD sessions to eligible caregiver-child dyads (6-30 months) in 25 sites [T]; we added take-home play materials in Cycle 2 to 25 sites [T+]. We used differences-in-differences with administrative data to analyze the effect of offering ECD sessions on monthly PARN attendance (T+/T vs. C) among age-eligible children and the impact of toy boxes/libraries on monthly ECD session attendance (T + vs. T). We used random intercept models to analyze characteristics associated with program registration.

RESULTS

We analyzed data for 9,408 dyads; 30% and 32% registered for the program in Cycle 1 and 2 (respectively). On average, CHWs delivered 11.4 sessions (SD: 1.5). Children from wealthier households who already attended PARN sessions were more likely to register, and we found no effect of T or T + on PARN attendance. Adding play materials did not affect monthly ECD session attendance. Children from more populated sites were less likely to participate in both ECD and PARN sessions.

CONCLUSIONS

Integrating new services for ECD into the health system was feasible and did not reduce dyad participation in existing services. Investment in health services in more populated areas is needed to provide coverage to all eligible children. Novel strategies should be explored to engage the most vulnerable children in new and existing health services.

Tools for screening maternal mental health conditions in primary care settings in sub-Saharan Africa: systematic review

Introduction

In sub-Saharan Africa, pregnant and postpartum women with mental health problems are often missed in healthcare systems. To address this, a practical and simple screening tool for maternal mental health should be available to primary healthcare workers. An important step toward having such a tool is to assess the existing tools and their effectiveness in primary care settings.

Methods

We systematically searched PubMed, LILAC, CINAHL, Google Scholar, African Index Medicus, HINARI, and African Journals Online from inception to 31 January 2023, without language restriction. Reference lists of retrieved articles were reviewed and experts in the field were contacted for studies not captured by our searches. All retrieved records were collated in Endnote, de-duplicated, and exported to Rayyan for screening. Study selection and data extraction were done by at least two reviewers using a pre-tested flow chart and data extraction form. Disagreements between reviewers were resolved through discussion. We contacted primary authors for missing or insufficient information and conducted a content analysis of the psychometric properties of the tools.

Results

In total, 1,181 studies were retrieved by our searches, of which 119 studies were included in this review. A total of 74 out of 119 studies (62%) were screened for depression during pregnancy and or the postpartum period. The Edinburg Postpartum Depression Scale (EPDS) and the Patient Health Questionnaire (PHQ-9) were the most commonly used tools. In total, 12 studies reported specificity and sensitivity for tools for measuring depression (EPDS, PHQ-9, and Whooley) and psychological distress [Self Report Questionnaire (SRQ) and Kessler Psychological Distress Scale (KPDS)]. The average sensitivity and specificity of the EPDS reported were 75.5 and 76.5%, respectively, at a cut-off of ≥13. The EPDS appears to be the most acceptable, adaptable, user-friendly, and effective in screening for maternal mental health conditions during pregnancy and postpartum. However, the methodological approach varied for a particular tool, and documentation on the attributes was scanty.

Conclusion

The EPDS was the most commonly used tool and considered as most acceptable, adaptable, user-friendly, and effective. Information on the performance and psychometric properties of the vast majority of screening tools was limited.

Virtual Post-Intervention Speech and Language Assessment of Toddler and Preschool Participants in Babble Boot Camp

PURPOSE

Babble Boot Camp (BBC) is a parent-implemented telepractice intervention for infants at risk for speech and language disorders. BBC uses a teach-model-coach-review approach, delivered through weekly 15-min virtual meetings with a speech-language pathologist. We discuss accommodations needed for successful virtual follow-up test administration and preliminary assessment outcomes for children with classic galactosemia (CG) and controls at age 2.5 years.

METHOD

This clinical trial included 54 participants, 16 children with CG receiving BBC speech-language intervention from infancy, age 2 years, five children receiving sensorimotor intervention from infancy and changing to speech-language intervention at 15 months until 2 years of age, seven controls with CG, and 26 typically developing controls. The participants' language and articulation were assessed via telehealth at age 2.5 years.

RESULTS

The Preschool Language Scale-Fifth Edition (PLS-5) was successfully administered with specific parent instruction and manipulatives assembled from the child's home. The GFTA-3 was successfully administered to all but three children who did not complete this assessment due to limited expressive vocabularies. Referrals for continued speech therapy based on PLS-5 and GFTA-3 scores were made for 16% of children who received BBC intervention from infancy as compared to 40% and 57% of children who began BBC at 15 months of age or did not receive BBC intervention, respectively.

CONCLUSIONS

With extended time and accommodations from the standardized administration guidelines, virtual assessment of speech and language was possible. However, given the inherent challenges of testing very young children virtually, in-person assessment is recommended, when possible, for outcome measurements.

Mediating Effect of the Parent-Child Relationship on the Association Between Maternal Nurturance and Early Child Development: A Longitudinal Study During the COVID-19 Pandemic

Background

Research on the specific pathways from maternal nurturance to early child development remains limited. Grounded in transactional theory, this study is the first to examine these pathways through the parent-child relationship.

Methods

This longitudinal study involved mothers of children aged 1-3 years. Data on sociodemographic characteristics, Comprehensive General Parenting Questionnaire, and Child-Parent Relationship Scale were collected at Time 1, when children were 1 year old. At Time 2, when children were 3 years old, Caregiver-Reported Early Development Instruments were measured. Structural equation modeling (SEM) was used to explore direct and indirect pathways from maternal nurturance to early child development.

Results

A total of 1145 mother-child dyads participated, with children averaging 32 months (SD = 6.4) and mothers averaging 28.7 years (SD = 4.0). Maternal nurturance had significant direct (β = 0.271), indirect (β = 0.065), and total (β = 0.336) effects on early child development. Direct effects accounted for 80.7% of the total effects, while indirect effects accounted for 19.3%. Maternal nurturance indirectly predicted higher early child development through increased parent-child closeness (β = 0.048), explaining 14.3% of the total effects. Maternal nurturance indirectly promoted early child development through reduced parent-child conflict (β = 0.017), explaining 5.1% of the total effects.

Conclusion

The novelty of this study lies in its demonstration of the mediating role of the parent-child relationship in the effect of maternal nurturance on early child development. This longitudinal study provides insights for governments agencies, policymakers, and healthcare workers to develop intervention programs that enhance maternal nurturance through the parent-child relationship to promote early child development.

Caregiver mental health and school-aged children's academic and socioemotional outcomes: Examining associations and mediators in Northern Ghana

While there is a strong link between caregiver mental health, caregiver engagement, and child development, limited research has examined the underlying mechanisms of these associations in Africa. We examined the mediating role of dimensions of caregiver engagement in the association of caregiver psychological distress with children's academic and socioemotional outcomes in Ghana. Data came from 4,714 children (aged 5-17 years) and their caregivers in five regions of northern Ghana. Caregiver psychological distress and engagement (i.e., engagement in education, emotional supportiveness, and parenting self-efficacy) were self-reported by children's primary caregiver. Children's academic (literacy and numeracy) and socioemotional (prosocial skills and socioemotional difficulties) outcomes were directly assessed using validated measures. Structural equation modelling was used to estimate mediation models. We tested moderation by caregiver exposure to formal education, child's age, and child's sex. Fourteen percent of caregivers experienced elevated psychological distress. Higher levels of psychological distress were associated with children's poorer literacy and numeracy skills, and higher socioemotional difficulties, but not prosocial skills. The mediating role of caregiver engagement varied by caregiver exposure to formal education but not child's age or sex. Caregiver engagement in education explained the association between psychological distress and children's literacy skills (but not numeracy or socioemotional) in families where the caregiver had no formal education (indirect effect: β = 0.007 [95% CI: 0.000, 0.016]), explaining 23% of the association. No mediator explained the association of psychological distress with child outcomes among families where the caregiver had some formal education. The mechanisms through which caregiver psychological distress is associated with child outcomes in rural Ghana differ as a function of caregivers' exposure to formal education. These results highlight the importance of developing multi-component and culturally-sensitive programs to improve child outcomes. Further research in similar contexts is needed to advance scientific understanding on how to effectively promote child and family wellbeing.

In-person versus remote (mHealth) delivery for a responsive parenting intervention in rural Kenya: a cluster randomized controlled trial

BACKGROUND

An estimated 43% of children under age 5 in low- and middle-income countries (LMICs) experience compromised development due to poverty, poor nutrition, and inadequate psychosocial stimulation. Numerous early childhood development (ECD) parenting interventions have been shown to be effective at improving ECD outcomes, at least in the short-term, but they are (a) still too expensive to implement at scale in low-resource and rural settings, and (b) their early impacts tend to fade over time. New approaches to deliver effective ECD parenting interventions that are low-cost, scalable, and sustainable are sorely needed.

METHODS

Our study will experimentally test a traditional in-person group-based delivery model for an evidence-based ECD parenting intervention against a hybrid-delivery model that increasingly substitutes in-person meetings with remote (mHealth) delivery via smartphones, featuring audiovisual content and WhatsApp social interactions and learning. We will assess the relative effectiveness and cost of this hybrid-delivery model compared to in-person delivery and will extend the interventions over two years to increase their ability to sustain changes in parenting behaviors and ECD outcomes longer-term. Our evaluation design is a cluster Randomized Controlled Trial (cRCT) across 90 villages and approximately 1200 households. Midline and endline surveys collected 12 and 24 months after the start of the interventions, respectively, will examine short- and sustained two-year intention-to-treat impacts on primary outcomes. We will also examine the mediating pathways using mediation analysis. We hypothesize that a hybrid-delivery ECD intervention will be lower in cost, but remote interactions among participants may be an inferior substitute for in-person visits, leaving open the question of the most cost-effective program.

DISCUSSION

Our goal is to determine the best model to maximize the intervention's reach and sustained impacts to improve child outcomes. By integrating delivery into the ongoing operations of local Community Health Promoters (CHPs) within Kenya's rural health care system, and utilizing new low-cost technology, our project has the potential to make important contributions towards discovering potentially scalable, sustainable solutions for resource-limited settings.

Neurological examination of healthy term infants at ages 6 and 10 weeks in Tshwane District

Background

Globally, there is a significant gap in detailed neurodevelopmental data for infants under 3 months, despite 6 weeks being identified a critical milestone for neuro-behavioural development. Normative values and optimal scores for healthy infants at 6 and 10 weeks postnatally are lacking in many settings. In South Africa, the statutory neurodevelopmental assessments at these ages exclude notable characteristics of central nervous system maturation and limit opportunities to collect data of early developmental progress.

Objectives

Our study aimed to assess developmental characteristics of healthy term infants aged 6 and 10 weeks using the Hammersmith Neonatal Neurological Examination (HNNE).

Method

A prospective longitudinal study was performed on 35 healthy term-born infants from low-risk pregnancies at 6 and 10 weeks' postnatal age in the Tshwane district. The statuses of infants' neurodevelopment in six domains were recorded using the HNNE. Optimality scores were derived from the raw scores of 34 items, using the 10th and 5th percentiles as cut-off points.

Results

Evidences of neurodevelopmental advancements, particularly in posture, muscle tone and visual behaviour between 6 and 10 weeks were illustrated, and total examination optimality scores of 29.5 in 91% and 31.5 in 94% of infants were recorded at 6 and 10 weeks, respectively.

Conclusion

This article provides data on the neurodevelopment characteristics of infants at and between 6- and 10-weeks post term ages.

Clinical Implications

The findings support the viewpoint to identify important milestone characteristics during early screening.

A comparison between different models of delivering maternal cash transfers in Myanmar

As part of a randomized controlled trial conducted in Myanmar between 2016 and 2019, we explore the performance of a maternal cash transfer program across villages assigned to different models of delivery (by government health workers vs loan agents of a non-governmental organization) and identify key factors of success. Measures include enrolment inclusion and exclusion errors, failures in payment delivery to enrolled beneficiaries (whether beneficiaries received any transfer, fraction of benefits received and whether there were delays and underpayment of benefit amounts) and whether beneficiaries remained in the program beyond eligibility. We find that women in villages where government health workers delivered cash transfers received on average two additional monthly transfers, were 19.7% more likely to receive payments on time and in-full and were 14.6% less likely to stay in the program beyond eligibility. With respect to the primary health objective of the program-child nutrition-we find that children whose mother received cash by government health workers were less likely to be chronically malnourished compared to those whose mother received cash by loan agents. Overall, the delivery of cash transfers to mothers of young children by government health workers outperforms the delivery by loan agents in rural Myanmar. Qualitative evidence suggests two key factors of success: (1) trusted presence and past interactions with targeted beneficiaries and complementarities between government health workers' expertise and the program; and (2) performance incentives based on specific health objectives along with top-down monitoring. We cannot exclude that other incentives or intrinsic motivation also played a role.

Caregivers' perspectives of early developmental tele-assessments in challenging circumstances

BACKGROUND

 Outbreaks, such as the COVID-19 pandemic in 2020, exacerbate barriers to accessing early childhood developmental care. Tele-assessment may serve as an innovative approach to developmental monitoring to overcome service delivery amidst challenging circumstances. It is vital to collect caregivers' perspectives of this potential service delivery method to inform clinical decision making.

OBJECTIVES

 This study aimed to determine caregivers' perspectives of interview-based early developmental tele-assessment in a South African context.

METHOD

 Thirty caregivers of children (aged birth - 36 months) completed a caregiver-report developmental assessment via a telecommunications platform, as well as an online questionnaire probing their perspectives on the tele-assessment.

RESULTS

 Most participants (96.7%, n = 29 out of 30) rated their overall experience of the tele-assessment as positive; however, 53.8% (n = 14 out of 26 that answered the question) indicated that they would additionally still prefer in-person assessment.

CONCLUSION

 Tele-assessment appears to be a viable approach for caregivers to access developmental care during circumstances such as COVID-19.Contribution: This study provided valuable insight into a novel approach using interview-based early developmental tele-assessment and the perspectives of caregivers thereof.

A longitudinal multi-centric cohort study assessing infant neurodevelopment delay among women with persistent postpartum depression in Nepal

BACKGROUND

Infant neurodevelopment in the first years after birth is determined by multiple factors, including parental care and maternal mental wellbeing. In this study, we aim to assess the impact of persistent maternal depressive symptoms during the first 3 months postpartum on infant neurodevelopment at 6 months.

METHODS

Using a longitudinal cohort design, 1253 mother-infant pairs were followed up at 7, 45, and 90 days to assess postpartum depressive symptoms using the Edinburgh Postnatal Depression Scale (EPDS); infants were followed up at 6 months to assess neuro-developmental status using the WHO's Infant and Young Child Development (IYCD) tool. A generalized linear regression model was used to assess the association between persistent postpartum depressive symptoms and infant neurodevelopmental delay at 6 months. A generalized linear mixed model (GLMM) with a hospital as a random intercept was used to assess the persistent postpartum depressive symptoms with an IYCD score. Linear regression was used to compare the IYCD scores between exposure groups.

RESULTS

In the study population, 7.5% of mothers had persistent depressive symptoms, and 7.5% of infants had neurodevelopmental delay. Infants born to mothers with persistent depressive symptoms had a higher proportion of neurodevelopmental delay than infants born to women without persistent symptoms (48.6% vs 5.1%; p < 0.001). In the adjusted regression model, infants whose mothers had persistent depressive symptoms at 7, 45, and 90 days had a 5.21-fold increased risk of neurodevelopmental delay (aRR, 5.21; 95% CI, 3.17, 8.55). Mean scores in the motor domain (12.7 vs 15.2; p < 0.001) and language domain (6.4 vs 8.5; p < 0.001) were significant when a mother had persistent depression vs. no depression. Mean scores in the general behavioral domain (5.9 vs 10.4, p < 0.001) and the socio-emotional domain (15.4 vs 17.7; p < 0.001) were significantly different when a mother had persistent depression vs no persistent depression.

CONCLUSIONS

Our results suggest that 6-month-old infants are at higher risk for neurodevelopment delays if their mother reports persistent symptoms of depression from 7 to 90 days postpartum. The neurodevelopmental delay can be observed in all functional domains. Preventive intervention to reduce maternal postpartum depression may reduce the impact on infant developmental delay.

A qualitative study of maternal and paternal parenting knowledge and practices in rural Mozambique

BACKGROUND

Providing nurturing care for young children is essential for promoting early child development (ECD). However, there is limited knowledge about how mothers and fathers across diverse contexts in sub-Saharan Africa care for their children and from whom they receive guidance and support in their caregiving roles. We aimed to examine caregivers' nurturing care practices and sources of parenting knowledge in rural Mozambique.

METHODS

This is a secondary analysis using data from a qualitative evaluation of a pilot intervention to improve nurturing care for early child health and development within existing health systems. The evaluation was conducted across three primary care health facilities and their catchment areas in Nampula province, Mozambique. For this study, we analyzed data from in-depth interviews conducted with 36 caregivers (32 mothers and 4 fathers) to investigate mothers' and fathers' daily caregiving experiences. Data were analyzed using thematic content analysis.

RESULTS

Caregivers described various caregiving roles relating to general caregiving of young children (e.g., feeding, bathing, caring for child's health) and stimulation (e.g., play and communication) activities. Mothers more commonly engaged in general caregiving activities than fathers, whereas both mothers and fathers engaged in stimulation activities. Other family members, including siblings, grandparents, and aunts/uncles, were also actively engaged in general caregiving activities. With respect to sources of parenting knowledge, caregivers received parenting guidance and support primarily from their own mothers/parents and facility-based health providers.

CONCLUSIONS

These findings highlight the importance of adopting a holistic approach involving caregivers and their context and reveal potential strategies to promote caregiving and ECD in rural Mozambique and similar contexts.

You are What Your Parents Expect: Height and Local Reference Points

Recent estimates are that about 150 million children under five years of age are stunted, with substantial negative consequences for their schooling, cognitive skills, health, and economic productivity. Therefore, understanding what determines such growth retardation is significant for designing public policies that aim to address this issue. We build a model for nutritional choices and health with reference-dependent preferences. Parents care about the health of their children relative to some reference population. In our empirical model, we use height as the health outcome that parents target. Reference height is an equilibrium object determined by earlier cohorts' parents' nutritional choices in the same village. We explore the exogenous variation in reference height produced by a protein-supplementation experiment in Guatemala to estimate our model's parameters. We use our model to decompose the impact of the protein intervention on height into price and reference-point effects. We find that the changes in reference points account for 65% of the height difference between two-year-old children in experimental and control villages in the sixth annual cohort born after the initiation of the intervention.

Early childhood development and nutritional status in urban Ethiopia

Early childhood development (ECD) is crucial for better health and well-being throughout life, but few studies have examined how ECD relates to child malnutrition. This is mainly due to lack of reliable and disaggregated data on ECD. We estimated the prevalence of ECD delays (communication, fine motor, gross motor, problem-solving and personal-social) and examined how different ECD domains were associated with child nutritional status in urban Ethiopia. Using a community-based cross-sectional survey design, 627 mother-child (12-36 months old) pairs were included in the study. The ECD was assessed using the Age and Stage Questionnaire (ASQ-3), and the nutritional status was assessed using anthropometric measurements. The association between the ECD domains and nutritional status was analysed using ordinal logistic regression, adjusting for confounding variables. Delays in ECD domains were common, especially in fine motor domain (41.9%); and more than half of the children were stunted (52.8%). Stunting and underweight were associated with ECD delays, while wasting was not. Accordingly, stunted children were more likely to have worst ECD delays in fine motor (odds ratios [OR] = 1.54; 95% confidence interval [CI]: 1.11; 2.15), gross motor (OR = 1.47; 95% CI: 1.05; 2.04) and problem-solving (OR = 1.41; 95% CI: 1.02; 1.96) domains compared to non-stunted children. Similarly, underweight children were more likely to have worse ECD delays in gross motor (OR = 1.91; 95% CI: 1.20; 3.04) and fine motor (OR = 1.90; 95% CI: 1.15; 3.15) domains compared to normal children. Coordinated and targeted ECD interventions, such as nurturing care, should be promoted and implemented widely to improve ECD outcomes and child nutrition.

Nurturing care assets for food security: a community asset mapping approach

BACKGROUND

Zip codes classified by the Food Insecurity Index with moderate and high food insecurity (FI) risk can be a threat to the health and well-being of children during the first 1,000 days (from pregnancy to 2 years). The presence of nurturing care assets (i.e., stable environments that promote health and nutrition, learning opportunities, security and safety, and responsive relationships) can contribute to supporting families and their communities, and ultimately reduce systemic barriers to food security. We aimed to identify and characterize nurturing care assets in under-resourced communities with moderate and high FI risk.

METHODS

Four steps were used to conduct a Community Asset Mapping (CAM): (1) review of community documents across five zip codes in Clark County, Nevada (2), engagement of community members in identifying community assets (3), definition of the assets providing nurturing care services, and (4) classification of assets to nurturing care components, i.e., good health, adequate nutrition, safety and security, opportunities for early learning, and responsive caregiving. The Food Insecurity Index was used to determine FI risk in each zip code. Analyses explored whether disparities in nurturing care assets across zip codes with moderate and high FI exist.

RESULTS

We identified 353 nurturing care assets across zip codes. A more significant number of nurturing care assets were present in zip codes with high FI risk. The adequate nutrition component had the most assets overall (n = 218, 61.8%), while the responsive caregiving category had the least (n = 26, 7.4%). Most of the adequate nutrition resources consisted of convenience stores (n = 96), food pantries (n = 33), and grocery stores (n = 33). Disparities in the number and type of good health, early learning, and security and safety assets were identified within zip codes with high FI risk compared to moderate FI risk.

CONCLUSIONS

The quantity and type of nurturing care assets can exacerbate existing demographic disparities across zip codes, which are tied to barriers to access to food in under-resourced communities in Clark County, Nevada. Co-creating a nurturing care asset-based zip code strategy to address high FI risk will require strengthening systems across existing nurturing care assets.

Effect of a parenting and nutrition education programme on development and growth of children using a social safety-net platform in urban Bangladesh: a cluster randomized controlled trial

Background

Although sustainable development goals mandate for quality early childhood development (ECD) interventions for children <8 years, little occurs for children <3 years, especially in urban settings in low-and-middle-income countries (LMICs). Our primary objective was to measure the effect of an ECD-focused parenting and nutrition education on children's development through home visits using a social safety net platform of urban Bangladesh.

Methods

A cluster randomized controlled trial was conducted with mothers of children aged 6-16 months in 20 clusters across the Rangpur city, Bangladesh. The intervention group received fortnightly ECD-focused parenting and nutrition education at homes by local Community Health Workers (CHWs) for one year. Bayley-III was used to measure children's cognitive, language and motor development. Data were analyzed using intention to treat. ClinicalTrials.gov Identifier: NCT03753646.

Findings

Out of 599 mother-child dyads, 56.6% mothers were aged ≤ 25 years old. After one year, the intervened children had higher cognitive [Effect size Cohen's d; 0.42 SD (95% CI: 0.58-0.25)], language (0.38 SD, 95% CI: 0.55-0.22) and motor (0.17 SD, 95% CI: 0.01-0.34) development. In the intervention group, mothers experienced less violence [Odds ratio; 0.6 (95% CI: 0.4-1.0)] and fathers engaged more (0.23 SD, CI: 0.39-0.06) in ECD activities with their children compared to the comparison group. Total home stimulation and mothers' knowledge on child care were also improved in the intervention. But the children's growth was not improved.

Interpretation

This ECD programme improves the development of children of young mothers in urban settings using a social safety-net platform. The evidence may help in increasing ECD coverage in urban areas in LMICs.

The impact of ever breastfeeding on children ages 12 to 36 months: A secondary data analysis of the standardization study of the Dominican system for evaluating early childhood development

Extensive research has shown that breastfeeding offers many benefits to children, including advantages in lifelong health, physical development, cognitive function, behavior, and brain development, compared to those not breastfed. In the Dominican Republic, the prevalence of exclusive breastfeeding among infants aged 0-6 months remains low, and the lack of a surveillance system has made it challenging to measure the impact of breastfeeding on early childhood development (ECD). This study aims to address the effect of ever breastfeeding on ECD. We conducted secondary data analysis from the Dominican System for Measuring Early Childhood Development (SIMEDID), a screening tool adapted and validated to the Dominican context that measures four areas of development: gross-motor, fine-motor, language, and socioemotional development. The data from SIMEDID can be cross-analyzed with other datasets generated by the National Institute for Early Childhood Comprehensive Care (INAIPI) that include information about breastfeeding. The children were evaluated during the standardization study of SIMEDID. To determine the breastfeeding impact, we: 1) conducted an analysis of covariance using ECD scores as dependent variables and ever breastfed as the independent variable, with age and sex as covariates (previously confirmed with an analysis of variance indicating the relevance of age and sex at birth in ECD); 2) analyzed the relative risk (RR) of developmental delay by breastfeeding status. We studied a sample of 699 Dominican children aged 12-36 months who receive services at INAIPI (the government institution responsible for administering comprehensive early childhood services). The results show that ever breastfed children had higher scores in overall ECD than those who were not; higher scores in language and fine motor development primarily drove this effect. The never breastfed group had a greater risk of developmental delay in fine motor and socioemotional development. These findings underscore the importance of promoting and supporting breastfeeding to improve child neurodevelopmental outcomes. This is particularly relevant in low-resource settings, where mothers may need additional support. Moreover, the study's results provide evidence of SIMEDID's validation, which can help inform future research and evidence-based decision-making toward optimal ECD in similar contexts.

Early Childhood Development Is Not Enough: In Defense of Children with Developmental Delays and Disabilities and Their Right to Family-Centered Early Childhood Intervention (In the Global South)

The international recognition of the critical importance of the early childhood phase has been firmly established through decades of rigorous research, evidence-based practices, and undeniable evidence of the returns on investment made during this formative period. Consequently, early childhood development has emerged as a top priority on both national and international agendas. This momentum reached a pinnacle in 2015 with the unanimous adoption of the 17 Sustainable Development Goals (SDGs) by the United Nations, which placed a particular emphasis on children under the age of five within the education-focused SDG 4, notably target 4.2, centered on ensuring that all girls and boys are ready for primary education through the provision of accessible "quality early childhood development, care and pre-primary education". However, the Global South reflects the glaring omission of addressing the needs of children at risk of poor development due to disabilities. This paper underscores the imperative for specialized early childhood intervention tailored to young children with disabilities and their families, commencing as early as possible following birth. It advocates for Early Childhood Intervention (ECI) as a service distinct from general Early Childhood Development (ECD), emphasizing the crucial role of families as active partners from the outset. Furthermore, the paper strengthens the case for Family-Centered Early Childhood Intervention (Fc-ECI) through the integration of evidence-based practices and an in-depth description of one such program in South Africa with specific reference to deaf and hard-of-hearing infants and their families. This model will be guided by core concepts outlined in WHO and UNICEF Early Childhood Intervention frameworks. Through this exploration, the paper aims to shed light on the urgent need for inclusive approaches to early childhood development, particularly for children with disabilities, and to advocate for the adoption of Family-Centered Early Childhood Intervention as a cornerstone of global efforts to ensure the holistic well-being and development of all children.

Coproduced, arts interventions for nurturing care (0-5 years) in low-income and middle-income countries (LMICs): a realist review

OBJECTIVES

Community-based arts interventions have the potential to support contextually relevant nurturing care programmes and policies that adapt to different settings. Understanding the distinctive features of using the arts in local, culturally specific ways in low/middle-income countries (LMICs); how this varies by context; and gaining a better understanding of the perspectives on desirable outcomes for communities is important evidence that this review generates.

DESIGN

We conducted a realist review of papers that covered outcomes related to child health or development (0-5 years) AND arts-based approaches AND community-based, participatory approaches AND based in LMICs using a range of databases and other networks. A coding framework was developed covering context, intervention, outcomes, mechanisms, study, sustainability, transferability and scalability.

RESULTS

The included papers reported 18 unique interventions. Interventions covered 14 countries, with evidence lacking for South America, Arab countries and parts of Africa. Lead authors came from mostly clinical science-based disciplines and from institutions in a different country to the country/countries studied. Intended outcomes from interventions included clinical, health systems/organisation, changes in practices/behaviours/knowledge/attitudes, and wider social and educational goals. We identified three demi-regularities (semi-predictable patterns or pathways of programme functioning): participatory design based on valuing different sources of expertise; dynamic adaptation of intervention to context; and community participation in arts-based approaches.

CONCLUSIONS

Our findings suggest that arts-based, nurturing care interventions have greater potential when they include local knowledge, embed into existing infrastructures and there is a clear plan for ongoing resourcing of the intervention. Studies with better documentation of the lessons learnt, regarding the intervention delivery process and the power dynamics involved, are needed to better understand what works, for whom and in which contexts.

Developing a context-relevant psychosocial stimulation intervention to promote cognitive development of children with severe acute malnutrition in Mwanza, Tanzania

More than 250 million children will not meet their developmental potential due to poverty and malnutrition. Psychosocial stimulation has shown promising effects for improving development in children exposed to severe acute malnutrition (SAM) but programs are rarely implemented. In this study, we used qualitative methods to inform the development of a psychosocial stimulation programme to be integrated with SAM treatment in Mwanza, Tanzania. We conducted in-depth interviews with seven caregivers of children recently treated for SAM and nine professionals in early child development. We used thematic content analysis and group feedback sessions and organised our results within the Nurturing Care Framework. Common barriers to stimulate child development included financial and food insecurity, competing time demands, low awareness about importance of responsive caregiving and stimulating environment, poor father involvement, and gender inequality. Caregivers and professionals suggested that community-based support after SAM treatment and counselling on psychosocial stimulation would be helpful, e.g., how to create homemade toys and stimulate through involvement in everyday chores. Based on the findings of this study we developed a context-relevant psychosocial stimulation programme. Some issues identified were structural highlighting the need for programmes to be linked with broader supportive initiatives.

A Factorial Randomized Controlled Trial to Optimize User Engagement With a Chatbot-Led Parenting Intervention: Protocol for the ParentText Optimisation Trial

BACKGROUND

Violence against children (VAC) is a serious public health concern with long-lasting adverse effects. Evidence-based parenting programs are one effective means to prevent VAC; however, these interventions are not scalable in their typical in-person group format, especially in low- and middle-income countries where the need is greatest. While digital delivery, including via chatbots, offers a scalable and cost-effective means to scale up parenting programs within these settings, it is crucial to understand the key pillars of user engagement to ensure their effective implementation.

OBJECTIVE

This study aims to investigate the most effective and cost-effective combination of external components to optimize user engagement with ParentText, an open-source chatbot-led parenting intervention to prevent VAC in Mpumalanga, South Africa.

METHODS

This study will use a mixed methods design incorporating a 2 × 2 factorial cluster-randomized controlled trial and qualitative interviews. Parents of adolescent girls (32 clusters, 120 participants [60 parents and 60 girls aged 10 to 17 years] per cluster; N=3840 total participants) will be recruited from the Ehlanzeni and Nkangala districts of Mpumalanga. Clusters will be randomly assigned to receive 1 of the 4 engagement packages that include ParentText alone or combined with in-person sessions and a facilitated WhatsApp support group. Quantitative data collected will include pretest-posttest parent- and adolescent-reported surveys, facilitator-reported implementation data, and digitally tracked engagement data. Qualitative data will be collected from parents and facilitators through in-person or over-the-phone individual semistructured interviews and used to expand the interpretation and understanding of the quantitative findings.

RESULTS

Recruitment and data collection started in August 2023 and were finalized in November 2023. The total number of participants enrolled in the study is 1009, with 744 caregivers having completed onboarding to the chatbot-led intervention. Female participants represent 92.96% (938/1009) of the sample population, whereas male participants represent 7.03% (71/1009). The average participant age is 43 (SD 9) years.

CONCLUSIONS

The ParentText Optimisation Trial is the first study to rigorously test engagement with a chatbot-led parenting intervention in a low- or middle-income country. The results of this study will inform the final selection of external delivery components to support engagement with ParentText in preparation for further evaluation in a randomized controlled trial in 2024.

Basic Environmental Supports for Positive Brain and Cognitive Development in the First Year of Life

Importance

Defining basic psychosocial resources to facilitate thriving in the first year of life could tangibly inform policy and enhance child development worldwide.

Objective

To determine if key environmental supports measured as a thrive factor (T-factor) in the first year of life positively impact brain, cognitive, and socioemotional outcomes through age 3.

Design, Setting, and Participants

This prospective longitudinal cohort study took place at a Midwestern academic medical center from 2017 through 2022. Participants included singleton offspring oversampled for those facing poverty, without birth complications, congenital anomalies, or in utero substance exposures (except cigarettes and marijuana) ascertained prenatally and followed up prospectively for the first 3 years of life. Data were analyzed from March 9, 2023, through January 3, 2024.

Exposures

Varying levels of prenatal social disadvantage advantage and a T-factor composed of environmental stimulation, nutrition, neighborhood safety, positive caregiving, and child sleep.

Main outcomes & measures

Gray and white matter brain volumes and cortical folding at ages 2 and 3 years, cognitive and language abilities at age 3 years measured by the Bayley-III, and internalizing and externalizing symptoms at age 2 years measured by the Infant-Toddler Social and Emotional Assessment.

Results

The T-factor was positively associated with child cognitive abilities (β = 0.33; 95% CI, 0.14-0.52), controlling key variables including prenatal social disadvantage (PSD) and maternal cognitive abilities. The T-factor was associated with child language (β = 0.36; 95% CI, 0.24-0.49), but not after covarying for PSD. The association of the T-factor with child cognitive and language abilities was moderated by PSD (β = -0.32; 95% CI, -0.48 to -0.15 and β = -0.36; 95% CI, -0.52 to -0.20, respectively). Increases in the T-factor were positively associated with these outcomes, but only for children at the mean and 1 SD below the mean of PSD. The T-factor was negatively associated with child externalizing and internalizing symptoms over and above PSD and other covariates (β = -0.30; 95% CI, -0.52 to -0.08 and β = -0.32; 95% CI, -0.55 to -0.09, respectively). Increasing T-factor scores were associated with decreases in internalizing symptoms, but only for children with PSD 1 SD above the mean. The T-factor was positively associated with child cortical gray matter above PSD and other covariates (β = 0.29; 95% CI, 0.04-0.54), with no interaction between PSD and T-factor.

Conclusions and Relevance

Findings from this study suggest that key aspects of the psychosocial environment in the first year impact critical developmental outcomes including cognitive, brain, and socioemotional development at age 3 years. This suggests that environmental resources and enhancement in the first year of life may facilitate every infant's ability to thrive, setting the stage for a more positive developmental trajectory.

Understanding child development and care integrality: Primary Health Care doctors and nurses' view

OBJECTIVE

To identify perceptions of primary care health professionals regarding the conceptual aspects of child development and propose strategies to address difficulties.

METHODS

This descriptive-analytical study was conducted in a small municipality in the countryside of the State of São Paulo, Brazil. The primary health care in this region is comprised of Family Health Units and Basic Health Units. The sample included 52 participants, consisting of doctors and primary care nurses. A questionnaire with open and closed questions was utilized, covering knowledge and practices related to child development. For this study, the first question of the questionnaire, which asked for a descriptive response about participants' understanding of child development, was employed. The responses were transcribed, and content analysis using the thematic approach was conducted.

RESULTS

Among the participants, 54% were nurses, and the average duration of working with the pediatric population was ten years. 80% reported never having undergone training in child development. The analysis of the responses revealed heterogeneity in the professionals' understanding of the conceptual dimension of child development. Additionally, there was an insufficient grasp of the theoretical and practical aspects and a scarcity of resources to support comprehensive care for children. A predominant biomedical model focusing on disease and biological aspects of child health was evident in defining the understanding of the subject.

CONCLUSIONS

The findings underscore the necessity of implementing health education initiatives and service projects in primary care settings. It is crucial to strengthen a comprehensive perspective of child health within the biopsychosocial model of the health-disease process.

Cost-effectiveness of a radio intervention to stimulate early childhood development: protocol for an economic evaluation of the SUNRISE trial in Burkina Faso

INTRODUCTION

Approximately 250 million children under 5 years of age are at risk of poor development in low-income and middle-income countries. However, existing early childhood development (ECD) interventions can be expensive, labour intensive and challenging to deliver at scale. Mass media may offer an alternative approach to ECD intervention. This protocol describes the planned economic evaluation of a cluster-randomised controlled trial of a radio campaign promoting responsive caregiving and opportunities for early learning during the first 3 years of life in rural Burkina Faso (SUNRISE trial).

METHODS AND ANALYSIS

The economic evaluation of the SUNRISE trial will be conducted as a within-trial analysis from the provider's perspective. Incremental costs and health outcomes of the radio campaign will be compared with standard broadcasting (ie, 'do nothing' comparator). All costs associated with creating and broadcasting the radio campaign during intervention start-up and implementation will be captured. The cost per child under 3 years old reached by the intervention will be calculated. Incremental cost-effectiveness ratios will be calculated for the trial's primary outcome (ie, incremental cost per SD of cognitive gain). A cost-consequence analysis will also be presented, whereby all relevant costs and outcomes are tabulated. Finally, an analysis will be conducted to assess the equity impact of the intervention.

ETHICS AND DISSEMINATION

The SUNRISE trial has ethical approval from the ethics committees of the Ministry of Health, Burkina Faso, University College London and the London School of Hygiene and Tropical Medicine. The results of the economic evaluation will be disseminated in a peer-reviewed journal and presented at a relevant international conference.

TRIAL REGISTRATION NUMBER

The SUNRISE trial was registered with ClinicalTrials.gov on 19 April 2019 (identifier: NCT05335395).

The effects of a large-scale home visiting programme for child development on use of health services in Brazil

Partnership between early childhood development interventions and primary health care services can help catalyse health care uptake by socially vulnerable families. This study aimed to assess the real-life effects of a large-scale home visiting programme [Primeira Infância Melhor (PIM)] in Brazil on the use of preventive (prenatal visits, well child visits, dentist visits and vaccination) and recovery (emergency room visits and hospitalization) health services. A quasi-experiment nested in a population-based birth cohort study was conducted. The intervention group was firstly defined as all children enrolled in PIM up to age 6 months, and afterwards stratified between those enrolled during pregnancy or after birth up to 6 months. Children receiving PIM were matched with controls on propensity scores based on 27 confounders to estimate effects on health service use from prenatal to age 2 years. Double adjustment was applied in outcome Quasi-Poisson regressions. No evidence was found for effects of PIM starting anytime up to 6 months (262 pairs), or for the children enrolled only after birth (133 pairs), on outcomes occurring after age 6 months. When the programme started during pregnancy (129 pairs), there was a 13% higher prevalence of adequate prenatal visits (prevalence ratio = 1.13; 95% confidence interval 1.01-1.27), but no effect on use of any other health service. Sensitivity analyses suggested longer participation in the programme with reduced visitor turnover might improve its impact on prenatal visits. Integration between PIM and primary health care was not adequate to affect overall patterns of contacts with health services. Nevertheless, prenatal home visits showed potential to increase health service contact during a sensitive period of development, indicating the need to start such programmes before birth, when there is more time for maternal care, and family engagement in a network of services is facilitated.

Practices and outcomes of responsive caregiving on child neurodevelopment and mental health across diverse global populations: a scoping review protocol

INTRODUCTION

Responsive caregiving (RC) leads to positive outcomes in children, including secure attachment with caregivers, emotional regulation, positive social interactions and cognitive development. Through our scoping review, we aim to summarise the practices and outcomes of RC in diverse caregiver and child populations from 0 to 8 years.

METHODS AND ANALYSIS

We will use the Arksey and O'Malley framework and the Joanna Briggs Institute methodology for scoping reviews. We shall present our findings as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for scoping review. Only peer-reviewed, English-language articles from 1982 to 2022 will be included from PubMed, Web of Science, APA PsychInfo, APA PsycArticles, SocINDEX and Google Scholar databases. Reference lists of included articles will also be screened. The search strategy will be developed for each database, and search results will be imported into Rayyan. Screening will be done in two phases: (1) titles and abstracts will be screened by two authors and conflicts will be resolved by mutual discussion between both or by consulting with a senior author; and (2) full-texts of shortlisted studies from the first phase will then be screened using the same inclusion/exclusion criteria. A data extraction form will be developed to collate relevant information from the final list of included articles. This form will be pilot tested on the first 10 papers and iteratively refined prior to data extraction from the remaining articles. Results will be presented in figures, tables and a narrative summary.

ETHICS AND DISSEMINATION

No ethics approval needed as the review shall only use already published data. We shall publish the review in an open-access, peer-reviewed journal and disseminate through newsletters, social media pages, and presentations to relevant audiences.

Perinatal depression and infant and toddler neurodevelopment: A systematic review and meta-analysis

Many studies have focused on the effect of perinatal depression on neurodevelopment among children and adolescents. However, only a few studies have explored this relationship in infants and toddlers with inconsistent results. We performed a systematic review and meta-analysis to evaluate the association between perinatal depression and infant and toddler neurodevelopment during the first two postnatal years. Twenty-three studies were included in this meta-analysis. Perinatal depression was associated with poorer cognitive (Cohen's d = -0.19, SE= 0.06, 95% CI = -0.30 to -0.08), language (Cohen's d = -0.24, SE = 0.09, 95% CI = -0.40 to -0.07), and motor (Cohen's d = -0.15, SE = 0.05, 95% CI = -0.26 to -0.05) development. Subgroup analyses showed that the types of maternal depression (prenatal depression vs. postnatal depression), the method of measuring maternal depression (rating scale vs. diagnostic interview), and the time interval between assessment of exposure and outcome had an impact on the observed effect about neurodevelopment of infants and toddlers. In addition, the results of our study pointed to a stronger significant association between prenatal depression and cognitive, language, and motor delays in infants and toddlers, whereas the association between postnatal depression and cognitive, language, and motor delays in infants and toddlers was not statistically significant. In conclusion, this study provided convincing evidence that the perinatal window is a sensitive period for offspring neurodevelopment.

A meta-analytic review of the implementation characteristics in parenting interventions to promote early child development

This review summarizes the implementation characteristics of parenting interventions to promote early child development (ECD) outcomes from birth to 3 years. We included 134 articles representing 123 parenting trials (PROSPERO record CRD42022285998). Studies were conducted across high-income (62%) and low-and-middle-income (38%) countries. The most frequently used interventions were Reach Up and Learn, Nurse Family Partnership, and Head Start. Half of the interventions were delivered as home visits. The other half used mixed settings and modalities (27%), clinic visits (12%), and community-based group sessions (11%). Due to the lack of data, we were only able to test the moderating role of a few implementation characteristics in intervention impacts on parenting and cognitive outcomes (by country income level) in the meta-analysis. None of the implementation characteristics moderated intervention impacts on cognitive or parenting outcomes in low- and middle-income or high-income countries. There is a significant need in the field of parenting interventions for ECD to consistently collect and report data on key implementation characteristics. These data are needed to advance our understanding of how parenting interventions are implemented and how implementation factors impact outcomes to help inform the scale-up of effective interventions to improve child development.

Perspectives on anemia: Factors confounding understanding of past occurrence

OBJECTIVE

This paper reviews factors confounding the understanding of the past occurrence of anemia. Using the evidence gathered, a framework is presented of ways forward to enable greater confidence in diagnosing acquired anemia in paleopathology, facilitating insights into longer-term perspectives on this globally relevant condition.

RESULTS

To date, porotic lesions have been central to paleopathological investigations of anemia. The fact that porotic bone lesions are omnipresent and have multiple causes but are likely to have a relatively low, age-related frequency in individuals with anemia, a condition that will have been common in past communities, is confounding.

METHODS

Establishing frameworks that move away from porotic lesions is proposed to facilitate higher levels of more accurate anemia diagnoses in paleopathology.

SIGNIFICANCE

Acceptance of the fundamental principle that anemia may be better considered as a condition requiring metric evaluation of bone structures, supplemented by careful consideration of lesions, will advance understanding of acquired anemia in past communities. Such an approach would provide a clear basis for further consideration of congenital conditions causing anemia, such as sickle-cell disease and thalassemia.

LIMITATIONS

This paper simply opens the conversation on the better diagnosis of anemia in paleopathology; it starts the iterative process of achieving some consensus and progress on diagnosing anemia in paleopathology.

SUGGESTIONS FOR FURTHER RESEARCH

Engagement with ideas presented, sharing data and development of metric parameters will assist in identifying the effects of marrow hyperplasia on bone, enabling more robust work on the important topic of anemia.
