Effect of a Center-Based Early Childhood Care and Education Program on Child Nutritional Status: A Secondary Analysis of a Stepped-Wedge Cluster Randomized Controlled Trial in Rural Sindh, Pakistan.

BACKGROUND: High-quality early childhood care and education (ECCE) programs can positively impact children's development. However, as an unintended consequence, ECCE attendance may also affect children's nutritional status. OBJECTIVE: We evaluated the effect of a center-based ECCE intervention on child nutritional outcomes in rural Pakistan. METHODS: This study utilized data from a stepped-wedge cluster randomized controlled trial of a center-based ECCE program that trained female youth to run high-quality preschools for children aged 3.5-5.5 y (Youth Leaders for Early Childhood Assuring Children are Prepared for School (LEAPS) program) in rural Sindh, Pakistan. The program did not include any school meals. A total of 99 village clusters were randomized to receive the LEAPS intervention in 3 steps, and repeated cross-sectional surveys were conducted to assess the impact on children (age: 4.5-5.5 y) at 4- time points. ITT analyses with multilevel mixed-effect models were used to estimate the effect of the intervention on child anthropometric outcomes. RESULTS: The analysis included 3858 children with anthropometric data from 4 cross-sectional survey rounds. The LEAPS intervention was found to have a positive effect on child height-for-age z score (mean difference: 0.13 z-scores; 95% confidence interval [CI]: 0.02, 0.24). However, there was a negative effect on weight-based anthropometric indicators, -0.29 weight-for-height z score (WHZ) (95% CI: -0.42, -0.15), -0.13 BMI z score (BMIZ) (95% CI: -0.23, -0.03), and -0.16 mid-upper arm circumference-for-age z score MUACZ (95% CI: -0.25, -0.05). An exploratory analysis suggested that the magnitude of the negative effect of LEAPS on WHZ, BMIZ, and weight-for-age z score (WAZ) was greater in the survey round during the COVID-19 lockdown. DISCUSSION: The LEAPS intervention positively affected child linear growth but had negative effects on multiple weight-based anthropometric measures. ECCE programs in low- and middle-income country settings should evaluate the integration of nutrition-specific interventions (eg school lunch, counseling on healthy diets) and infection control strategies to promote children's healthy growth and development.

Early Family Experiences and Neural Activity in Rural Pakistani Children: The Differential Role of Gender.

Adversity within low- and middle-income countries (LMICs) poses severe threats to neurocognitive development, which can be partially mitigated by high-quality early family experiences. Specifically, maternal scaffolding and home stimulation can buffer cognitive development in LMIC, possibly by protecting underlying neural functioning. However, the association between family experiences and neural activity remains largely unexplored in LMIC contexts. This study explored the relation of early family experiences to later cognitive skills and absolute gamma power (21-45 Hz), a neural marker linked to higher-order cognitive skills. Drawing data from the PEDS trial, a longitudinal study in rural Pakistan, we examined maternal scaffolding at 24 months and home stimulation quality at 18 months as predictors of verbal IQ, executive functions, and absolute gamma at 48 months for 105 mother-child dyads (52 girls). Maternal scaffolding interacted with gender to predict absolute gamma power, such that higher maternal scaffolding was related to higher gamma more strongly for girls. Maternal scaffolding also interacted with absolute gamma to predict executive functions, such that higher gamma was related to better executive functions only when maternal scaffolding was average to high. Individual differences in early family experiences may partially buffer the neural underpinnings of cognitive skills from adversity in LMIC.

"When I hold my daughter, she quiets, no need [for]any verbal conversation": A qualitative understanding of responsive caregiving in rural, Sindh Pakistan.

Responsive caregiving is associated with secure attachment and positive child developmental outcomes. However, there is some debate on whether responsive caregiving is a universal construct. Few studies have researched responsive caregiving in diverse cultural settings, particularly in low- and middle-income countries. In this study, we explore if and how responsive caregiving is conceptualized among mothers of children under 3-years-old in rural, Sindh Pakistan. A phenomenological qualitative study was implemented in Naushahro Feroze through in-depth interviews with twenty mothers. Mothers were asked about their aspirations for their children and how they would respond in a variety of different scenarios. Data were analyzed using thematic content analysis with an inductive-deductive coding scheme. There was substantial variation in mothers' described responsive behaviors and beliefs. Almost all mothers described using some form of responsive parenting. Responding to children's demands while the mother was preoccupied, using verbal responses to console children, and if mothers believed that children should be praised, lacked consensus. Most mothers described using breastfeeding for consolation and highlighted the importance of immediately consoling their crying child. The results suggest that there is a need for a more nuanced approach to understand caregiver behaviors across contexts.

Una sensible prestación de cuidado se asocia con una afectividad segura y con resultados positivos en el desarrollo del niño. Sin embargo, se da un debate sobre si la sensible prestación de cuidado es una estructura universal. Pocos estudios han investigado la sensible prestación de cuidado en diversos escenarios culturales, particularmente en países de bajas y medias entradas económicas. En este estudio, exploramos si la sensible prestación de cuidado está conceptualizada entre las madres de niños menores de 3 años en el área rural de Sindh en Pakistán y cómo lo está. Un estudio fenomenológico cualitativo se implementó usando datos de Naushahro Feroze (ciudad en la provincia de Sindh), por medio de entrevistas profundas con veinte madres. A las madres se les preguntó acerca de sus aspiraciones con respecto a sus niños y cómo ellas responderían en una variedad de diferentes escenarios. Se analizaron los datos usando un análisis de contenido temático con un esquema de codificación inductivo­deductivo. Hubo variación sustancial en las descripciones de las madres acerca de sus conductas y creencias sensibles. Casi todas las madres hicieron las descripciones usando alguna forma de crianza sensible. Faltó el consenso en el caso de responder a las peticiones de los niños mientras la madre estaba preocupada, en el uso de respuestas verbales para consolar a los niños, así como en el caso de si las madres creían que los niños debían ser elogiados. La mayoría de las madres hizo sus descripciones usando el amamantar como manera de consolar y subrayó la importancia de consolar inmediatamente al niño que llora. Los resultados sugieren que hay una necesidad de un acercamiento más matizado para comprender las conductas de prestación de cuidado a través de los contextos.

The unique relevance of executive functions and self-regulation behaviors for understanding early childhood experiences and preschoolers' outcomes in rural Pakistan.

Performance-based measures of children's executive functions (EFs) do not capture children's application of these skills during everyday emotionally-laden and socially-mediated interactions. The current study demonstrates the value of using assessor report of self-regulation behaviors (inhibitory control and positive affect/engagement) in addition to EF tasks when studying early childhood experiences and development in a rural lower-middle-income country setting. In a sample of 1302 disadvantaged 4-year-olds living in rural Pakistan, we found that directly assessed EFs were significantly related to assessor observations of children's inhibitory control and positive affect/engagement during a structured assessment protocol. However, EFs and two types of self-regulation behaviors demonstrated unique associations with children's (1) contextual experiences, as indexed by family socio-economic resources, participation in parenting interventions, and children's physical growth; and (2) age-salient developmental outcomes, as indexed by direct assessment of pre-academic skills and maternal report of prosocial behaviors and behavior problems. First, family wealth uniquely predicted only observed positive affect/engagement, whereas maternal education uniquely predicted only EFs. Second, children's antecedent linear growth was a significant predictor of both EFs and positive affect/engagement, but exposure to an enhanced nutrition intervention during the first 2 years of life and preschoolers' hair cortisol concentration were associated only with observed self-regulation behaviors. Finally, both EFs and observed positive affect/engagement uniquely predicted children's pre-academic skills. In contrast, only assessors' ratings of positive affect/engagement uniquely predicted maternal report of prosocial behaviors and only assessors' ratings of inhibitory control uniquely predicted maternal report of behavioral problems.

Child diet and mother-child interactions mediate intervention effects on child growth and development.

This study examined whether child diet and mother-child interactions mediated the effects of a responsive stimulation and nutrition intervention delivered from 2009 to 2012 to 1324 children aged 0-24 months living in rural Pakistan. Results showed that the intervention improved children's cognitive, language and motor development through child diet and mother-child interactions. Although the intervention did not improve child growth or socio-emotional development, we observed positive indirect effects on child growth via child diet and on socio-emotional development via both child diet and mother-child interactions. In addition, child diet emerged as a shared mechanism to improve both child growth and development, whereas mother-child interactions emerged as a distinct mechanism to improve child development. Nevertheless, our results suggest the two mechanisms were mutually reinforcing and that interventions leveraging both mechanisms are likely to be more effective at improving child outcomes than interventions leveraging only one of these mechanisms.

Biological sensitivity to context in Pakistani preschoolers: Hair cortisol and family wealth are interactively associated with girls' cognitive skills.

Many young children in low- and middle-income countries (LMICs) face heightened risk for experiencing environmental adversity, which is linked with poorer developmental outcomes. Children's stress physiology can shed light on why children are differentially susceptible to adversity. However, no known studies have examined whether links between adversity and children's development are moderated by children's stress physiology in LMICs. The present study revealed significant interactive effects of hair cortisol concentrations, an index of chronic physiological stress regulation, and family wealth on preschoolers' cognitive skills in rural Pakistan. In a sample of 535 4-year-old children (n = 342 girls), we found significant associations between family wealth and direct assessments of verbal intelligence, pre-academic skills, and executive functions only in girls with lower hair cortisol concentrations. Specifically, girls with lower cortisol concentrations displayed greater cognitive skills if they came from relatively wealthier families, but lower cognitive skills if they came from very poor families. There were no significant associations among boys. Results provide evidence of biological sensitivity to context among young girls in a LMIC, perhaps reflecting, in part, sex differences in daily experiences of environmental adversity.

"His mind will work better with both of us": a qualitative study on fathers' roles and coparenting of young children in rural Pakistan.

BACKGROUND: Parents are the primary providers of nurturing care for young children's healthy early development. However, the literature on parenting in early childhood, especially in low- and middle-income countries, has primarily focused on mothers. In this study, we investigate how parents make meaning of fathers' parenting roles with regards to their young children's early health and development in rural Pakistan. METHODS: Data were collected between January and March 2017 through in-depth interviews with fathers (N = 33) and their partners (N = 32); as well as separate focus group discussions with fathers (N = 7) and mothers (N = 7). Data were analyzed using thematic content analysis. RESULTS: Parents described a distinct division of roles between fathers and mothers; and also several shared caregiving roles of fathers and mothers. Specifically, parents highlighted aspects of fathers' coparenting and several common ways by which fathers supported their partners. We found that these gendered divisions in parenting roles were strongly embedded within a complex network of interacting factors across the individual, family, and sociocultural contexts of the study community. CONCLUSIONS: Our findings suggest a more family-centered conceptualization of fatherhood during early childhood that encompasses both fathers' direct engagement with their young children and their indirect contributions through coparenting, while recognizing a variety of contextual systems that shape paternal parenting. Future parenting interventions that reflect the lived experiences of both fathers and mothers as parents and partners may further enhance the nurturing care environments that are critical for promoting healthy early child development.

Pakistani preschoolers' number of older siblings and cognitive skills: Moderations by home stimulation and gender.

The present study examines the link between children's number of older siblings and their cognitive development, as measured by executive function (EFs) skills and verbal skills (VIQ) in a sample of 1,302 4-year-old children (54% boys) living in rural Pakistan. Specifically, we investigate whether the links between the number of older siblings and preschoolers' EFs and VIQ are moderated by preschoolers' quality of home stimulation and gender. Multivariate regressions revealed that the number of older siblings was positively associated with EFs for boys in homes with both higher and lower levels of stimulation, and for girls in homes with lower levels of stimulation (p < .05). However, the number of older siblings was negatively associated with EFs for girls from homes with higher levels of stimulation (p = .03). Further, the number of older siblings was positively associated with VIQ in homes with lower stimulation (p < .05), but not for higher stimulation homes. Gender was not a statistically significant moderator of the association between the number of older siblings and VIQ. Findings suggest that living with more older siblings may promote emerging EFs and VIQ among boys and girls with fewer opportunities for cognitive stimulation. However, more older siblings may hinder EF development for girls in the context of adequate home stimulation, perhaps due to inequitable allocation of resources among boys and girls in more affluent, larger families.

Early and concurrent home stimulation: Unique and indirect links with fine motor skills among 4-year-old children in rural Pakistan.

Fine motor skills enable children to make precise and coordinated movements with their hands and support their ability to engage in everyday activities and learning experiences. In a longitudinal study of 1,058 4-year-old children in rural Pakistan (n = 488 girls), we examined how prior and concurrent levels of home stimulation relate to change in fine motor skills from ages 2 to 4 while controlling for family wealth, maternal education, number of siblings at birth, prior and concurrent measures of children's physical growth and food insecurity, and prior motor skills at age 2. Moreover, we tested whether the association between early home stimulation and subsequent fine motor skills was mediated by physical growth, food insecurity, motor skills at age 2, and concurrent home stimulation. Results revealed that home stimulation at 18 months was positively associated with change in fine motor skills from ages 2 to 4, over and above family socioeconomic resources. This association was mediated by physical growth, food insecurity and motor skills at age 2. In contrast to home stimulation at 18 months, home stimulation at age 4 was positively associated with concurrent motor skills at age 4 when controlling for all antecedent family factors, as well as prior and concurrent measures of physical growth and food insecurity, and prior motor skills at age 2. Findings suggest that the preschool period may be an important window of time when physically and cognitively stimulating experiences at home uniquely relate to variability in fine motor development.

Evaluating implementation of LEAPS, a youth-led early childhood care and education intervention in rural Pakistan: protocol for a stepped wedge cluster-randomized trial.

BACKGROUND: The Sustainable Development Goals (SDGs) highlight the importance of investments in early childhood care and education (ECCE) and youth development. Given Pakistan's large young population, and gender and urban-rural inequalities in access to education, training, and employment, such investments offer opportunities. LEAPS is a youth-led ECCE program that trains female youth, 18-24 years, as Community Youth Leaders (CYLs) to deliver high-quality ECCE for children, 3.5-5.5 years, in rural Sindh, Pakistan. METHODS: We use a stepped wedge cluster-randomized trial to evaluate implementation of LEAPS. Ninety-nine clusters will be randomized to receive the intervention in one of three 7-month steps (33 clusters/step). The primary outcome is children's school readiness (indexed by the total score on the International Development and Early Learning Assessment (IDELA)). Secondary child outcomes are children's IDELA domain scores and executive functions. Data are collected in cross-sectional surveys of 1089 children (11 children/cluster from 99 clusters) aged 4.5-5.5 years at four timepoints (baseline and at the end of each step). Additionally, we will enroll three non-randomized youth participant open cohorts, one per step (33 CYLs: 66 comparison youth per cohort; 99:198 in total). Youth cohorts will be assessed at enrollment and every 7 months thereafter to measure secondary outcomes of youth personal and professional development, depressive symptoms, and executive functions. A non-randomized school cohort of 330 LEAPS students (10 students/cluster from 33 clusters) will also be enrolled and assessed during Step 1 after intervention rollout and at endline. The quality of the learning environment will be assessed in each LEAPS ECCE center and in a comparison center at two timepoints midway following rollout and at endline. A concurrent mixed-methods implementation evaluation will assess program fidelity and quality, and the extent to which a technical support strategy is successful in strengthening systems for program expansion. A cost evaluation will assess cost per beneficiary. Data collection for implementation and cost evaluations will occur in Step 3. DISCUSSION: Youth-led models for ECCE offer a promising approach to support young children and youth. This study will contribute to the evidence as a means to promote sustainable human development across multiple SDG targets. TRIAL REGISTRATION: ClinicalTrials.gov NCT03764436 .

Agreement between Fathers' and Mothers' Reported Stimulation and Associations with Observed Responsive Parenting in Pakistan.

Parental stimulation and responsiveness are associated with improved early child development outcomes. However, the majority of studies have relied on maternal-reported measures of only mothers' parenting practices. The purpose of this study was to assess the agreement between fathers' and mothers' reports of their own and their partner's engagement in stimulation and assess the degree to which parents' reported stimulation correlated with their observed responsive caregiving behaviors. Data were collected from 33 couples (33 fathers and 32 mothers) who had a child under 5 years of age in rural Pakistan. Paternal and maternal stimulation were measured based on reports of their own and their partner's practices in play and learning activities with the child. Paternal and maternal responsiveness were observed in a subsample of 18 families. Moderate agreement was found between paternal and maternal reports of their own and their partner's practices. Moderate associations were also found between self-reported measures of stimulation and observed responsive caregiving for both fathers and mothers. The strengths of agreement and associations were greater among couples who had higher quality coparenting relationships. Findings highlight the feasibility, reliability, and promise of assessing fathers' parenting in a low-resource setting, using similar methods as for mothers' parenting, to triangulate measures between reported and observed parenting and gain a deeper understanding of fathers' and mothers' unique caregiving contributions.

Integration of parenting and nutrition interventions in a community health program in Pakistan: an implementation evaluation.

Policy and program implementers require evidence on whether integrated psychosocial stimulation and nutrition interventions can be effectively delivered at-scale, how, and at what cost? To address some of these issues, a comprehensive evaluation of implementation was designed for a trial in Pakistan that integrated psychosocial stimulation and nutrition interventions in a community health service. The first objective was to describe, analyze, and assess the quality and accuracy of the implementation of the interventions. The second objective was to identify barriers and facilitators for uptake of interventions. A mixed-methods evaluation of implementation processes was conducted. Interventions were accepted by the community and health providers and there was evidence for behavior change uptake of the care for early childhood care recommendations. The new interventions did not dilute delivery of routine services. However, fidelity and quality required supportive supervision and active use of monitoring data, which would require attention in scale-up.

Maternal scaffolding in a disadvantaged global context: The influence of working memory and cognitive capacities.

The current study focuses on maternal cognitive capacities as determinants of parenting in a highly disadvantaged global context, where children's experiences at home are often the 1st and only opportunity for learning and intellectual growth. In a large sample of 1,291 biological mothers of preschool-aged children in rural Pakistan, we examined the unique association of maternal working memory skills (independent of related cognitive capacities) with cognitively stimulating parenting behaviors. Path analysis revealed that directly assessed working memory, short-term memory, and verbal intelligence independently predicted greater levels of observed maternal scaffolding behaviors. Mothers from poorer families demonstrated lower levels of working memory, short-term memory, and verbal intelligence. However, mothers' participation in an early childhood parenting intervention that ended 2 years prior to this study contributed to greater levels of working memory skills and verbal intelligence. Further, all 3 domains of maternal cognitive capacity mediated the effect of family economic resources on maternal scaffolding, and verbal intelligence also mediated the effect of early parenting intervention exposure on maternal scaffolding. The study demonstrates the unique relevance of maternal working memory for scaffolding behaviors that required continuously monitoring the child's engagement, providing assistance, and minimizing external distractions. These results highlight the importance of directly targeting maternal cognitive capacities in poor women with little or no formal education, using a 2-generation intervention approach that includes activities known to promote parental executive functioning and literacy.

Gamma power in rural Pakistani children: Links to executive function and verbal ability.

Children in low- and middle-income countries are at high risk of cognitive deficits due to environmental deprivation that compromises brain development. Despite the high prevalence of unrealized cognitive potential, very little is known about neural correlates of cognition in this population. We assessed resting EEG power and cognitive ability in 105 highly disadvantaged 48-month-old children in rural Pakistan. An increase in EEG power in gamma frequency bands (21-30Hz and 31-45Hz) was associated with better executive function. For girls, EEG gamma power also related to higher verbal IQ. This study identifies EEG gamma power as a neural marker of cognitive function in disadvantaged children in low- and middle-income countries. Elevated gamma power may be a particularly important protective factor for girls, who may experience greater deprivation due to gender inequality.

Effects of responsive stimulation and nutrition interventions on children's development and growth at age 4 years in a disadvantaged population in Pakistan: a longitudinal follow-up of a cluster-randomised factorial effectiveness trial.

BACKGROUND: A previous study in Pakistan assessed the effectiveness of delivering responsive stimulation and enhanced nutrition interventions to young children. Responsive stimulation significantly improved children's cognitive, language, and motor development at 2 years of age. Both interventions significantly improved parenting skills, with responsive stimulation showing larger effects. In this follow-up study, we investigated whether interventions had benefits on children's healthy development and care at 4 years of age. METHODS: We implemented a follow-up study of the initial, community-based cluster-randomised effectiveness trial, which was conducted through the Lady Health Worker programme in Sindh, Pakistan. We re-enrolled 1302 mother-child dyads (87% of the 1489 dyads in the original enrolment) for assessment when the child was 4 years of age. The children were originally randomised in the following groups: nutrition education and multiple micronutrient powders (enhanced nutrition; n=311), responsive stimulation (n=345), combined responsive stimulation and enhanced nutrition (n=315), and routine health and nutrition services (control; n=331). The data collection team were masked to the allocated intervention. The original enrolment period included children born in the study area between April 1, 2009, and March 31, 2010, if they were up to 2·5 months old without signs of severe impairments. The primary endpoints for children were development and growth at 4 years of age. Interventions were given in monthly group sessions and in home visits. The primary endpoint for mothers was wellbeing and caregiving knowledge, practices, and skills when the child was 4 years of age. Analysis was by intention to treat. The original trial is registered with ClinicalTrials.gov, number NCT00715936. FINDINGS: 1302 mother-child dyads were re-enrolled between Jan 1, 2013, and March 31, 2013, all of whom were followed up at 4 years of age. Children who received responsive stimulation (with or without enhanced nutrition) had significantly higher cognition, language, and motor skills at 4 years of age than children who did not receive responsive stimulation. For children who received responsive stimulation plus enhanced nutrition, effect sizes (Cohen's d) were 0·1 for IQ (mean difference from control 1·2, 95% CI -0·3 to 2·7), 0·3 for executive functioning (0·18, -0·07 to 0·29), 0·5 for pre-academic skills (7·53, 5·14 to 9·92) and 0·2 for pro-social behaviours (0·08, 0·03 to 0·13). For children who received responsive stimulation alone, effect sizes were 0·1 for IQ (mean difference with controls 1·7, -0·3 to 3·7), 0·3 for executive functioning (0·17, 0·07 to 0·27), 0·2 for pre-academic skills (3·86, 1·41 to 6·31), and 0·2 for pro-social behaviours (0·07, 0·02 to 0·12). Enhanced nutrition improved child motor development, with effect size of 0·2 for responsive stimulation plus enhanced nutrition (0·56, -0·03 to 1·15), and for enhanced nutrition alone (0·82, 0·18 to 1·46). Mothers who received responsive stimulation (with or without enhanced nutrition) had significantly better responsive caregiving behaviours at 4 years of child age than those who did not receive intervention. Effect size was 0·3 for responsive stimulation plus enhanced nutrition (1·95, 0·75 to 3·15) and 0·2 for responsive stimulation (2·01, 0·74 to 3·28). The caregiving environment had a medium effect size of 0·3 for all interventions (responsive stimulation plus enhanced nutrition 2·99, 1·50 to 4·48; responsive stimulation alone 2·82, 1·21 to 4·43; enhanced nutrition 3·52, 1·70 to 5·34). INTERPRETATION: Responsive stimulation delivered in a community health service can improve child development and care, 2 years after the end of intervention. Future analyses of these data are needed to identify which children and families benefit more or less over time. FUNDING: Grand Challenges Canada.
