Understanding modifiable caregiver factors contributing to child development among young children in rural Malawi.

This study examined modifiable caregiver factors influencing child development in Malawi using baseline data from 1,021 mothers and their children <2 years of age participating in a cluster-randomized controlled trial implemented in rural Malawi (2022-2025). We fit an evidence-based theoretical model using structural equation modelling examining four caregiver factors: (1) diet diversity (sum of food groups consumed in the past 24 h), (2) empowerment (assessed using the project-level Women's Empowerment in Agriculture Index), (3) mental health (assessed using the Self-Reported Questionnaire, SRQ-20), and (4) stimulation (number of stimulation activities the mother engaged in the past 3 days). Child development was assessed using the Malawi Development Assessment Tool (norm-referenced aggregate Z-score). The model controlled for child, caregiver, and household socioeconomic characteristics. Results showed that caregiver dietary diversity was directly associated with higher child development scores (standardized coefficient 0.091 [95% CI 0.027, 0.153]) and lower SRQ-20 scores -0.058 (-0.111, -0.006). Empowerment was directly associated with higher child development scores (0.071 [0.007, 0.133]), higher stimulation score (0.074 [0.013, 0.140]), higher dietary diversity (0.085 [0.016, 0.145]), and lower SRQ-20 scores (-0.068 [-0.137, -0.002]). Further, higher empowerment was indirectly associated with improved child development through enhancement of caregiver dietary diversity, with an indirect effect of 0.008 (0.002, 0.018). These findings highlight the important role that caregiver diet and empowerment play in directly influencing child development and other aspects of caregiver well-being. Interventions aimed at enhancing child development should consider these factors as potential targets to improve outcomes for children and caregivers.

Current Understanding of Giardia lamblia and Pathogenesis of Stunting and Cognitive Deficits in Children from Low- and Middle-Income Countries.

Purpose of Review: Giardia lamblia is a common intestinal parasite worldwide, mainly in children from low- and middle-income countries (LMIC). Also, it has been associated with increased intestinal permeability, stunting, and cognitive impairment. Nonetheless, the pathogenesis of long-term consequences is difficult to elucidate. Recent Findings: Recent studies try to understand the long-term consequences of Giardia infections. First, well-characterized studies associate Giardia with intestinal damage and child growth. Second, infections appear not to be associated with inflammation, but "lack of inflammation" may not, however, entirely exclude a pro-inflammatory pathway. Finally, some important amino acids are lower and could contribute to prolongate stunting and cognitive deficit. Summary: Giardia infections in LMIC used to be associated with child growth shortfalls, gut permeability, and cognitive deficits. Multifactorial effects could be associated with Giardia, including nutritional, altered microbiota, and generation of potentially toxic microbial metabolic byproducts, all together increasing risk of long-term outcomes.

Parental prenatal representations of the child are related to 18-month-old children's social-emotional competence.

Parental representations of the child are linked to positive developmental outcomes in children, but the impact of prenatal representations on early social-emotional development, particularly from fathers, is less understood. This study explores how fathers' and mothers' prenatal representations within two-parent families are associated with early social-emotional development. Prenatal representations of fathers (n = 88) and mothers (n = 92) were assessed between 28 and 32 weeks of gestation using the Working Model of the Child Interview, categorizing them as balanced or nonbalanced. The children's (n = 97; 49.5% girls) social-emotional and behavioral problems and competencies were measured at 18 months using the Brief Infant-Toddler Social and Emotional Assessment. Balanced prenatal representations of both parents were related to higher social-emotional competence in toddlers. However, prenatal representations were not related to social-emotional and behavioral problems. The results highlight the benefits of balanced prenatal representations in promoting early social-emotional competence in children.

Coparenting Profiles and Children's Socioemotional Outcomes in Unmarried Parents with Low-Income.

Objective: This study aimed to examine patterns of mother-father coparenting relationship quality and their associations with child empathy, emotional insecurity, and behavior problems in families with low income. Background: Given the growing number of nonmarital births and the high risk of relationship dissolution among cohabiting couples living with low income, it is important to examine the coparenting relationships among racially diverse unmarried couples from low-income contexts. To date, little research has assessed patterns of coparenting relationships and their associations with child socioemotional outcomes among this population. Method: Participants were 4,266 unmarried couples and their preschool-aged children from the Building Strong Families study. Latent profile analysis was conducted. Results: Latent profile analysis of survey data from mothers and fathers revealed four coparenting patterns: Profile 1: low quality, more negative maternal coparenting perceptions (7.2%); Profile 2: moderate-high quality, high congruence, slightly more negative paternal coparenting perceptions (25.2%); Profile 3: low congruence, severely more negative maternal coparenting perceptions (11.8%); and Profile 4: mutual high-quality coparenting (55.8%). Conclusion: Children of parents with the mutual high-quality coparenting profile had the most positive outcomes according to maternal reports of child socioemotional development. Highly congruent and positive perceptions of the other parent as a coparent were found to be significant promotive factors for positive child socioemotional development. Implications: Family strengthening policies and programs for unmarried couples with low income should target and support the development of mutually satisfying, high-quality coparenting relationships, with the ultimate goal to improve developmental outcomes for young children in such families.

Factors influencing on gross motor skills in infants: Implications for walking development.

BACKGROUND: This longitudinal study aimed to explore the impact of containers on gross motor percentile from 8 to 13 months corrected age during the walking development in moderate to late preterm infants. METHODS: Sixty preterm infants were enrolled in this study, and their monthly assessment the gross motor percentile using the Alberta Infant Motor Scale. Monthly parent interviews focused on collecting information about container characteristics. RESULTS: Infants exhibited fluctuating percentiles in gross motor development, averaging 37.81 (SD = 21.9; SEM = 1.4). The gross motor skills percentiles varied between 2 and 86 points across the six assessments. Factors significantly associated with gross motor development percentiles were a large container size (Coef. = 15.29; p < 0.001*) and a container with a soft floor surface (Coef. = 3.64; p = 0.042*). CONCLUSION: Healthy preterm infants exhibited minimal instability in gross motor development and attained walking independently by 13 months. Placing preterm infants in a baby container during their first year should prioritize a wide space and a soft floor surface to enhance gross motor development.

Impact of family and caregiver factors on development and behaviours in maltreated young children.

Introduction: This study aimed to evaluate the prevalence of developmental and emotional/ behavioural concerns in maltreated children and to examine the impact of adverse family/caregiver risk factors on these outcomes. Method: We analysed family demographic and baseline data of 132 maltreated children and their caregivers from a family support programme in Singapore. We examined the associations of 3 main risk factors (i.e., caregiver mental health, educational attainment, and family socio-economic status [SES]) with developmental/behavioural outcomes using multivariable logistic regression, controlling for caregiver relationship to the child. Caregiver mental health was assessed using the Patient Health Questionnaire 9 (PHQ-9) and General Anxiety Disorder 7 (GAD-7) tools. Developmental/behavioural outcomes were assessed using the Ages and Stages Questionnaires (ASQ-3), ASQ-Social-Emotional (ASQ-SE), and the Child Behaviour Checklist (CBCL). Results: The children ranged in age, from 2 months to 3 years 11 months (median age 1.7 years, interquartile range [IQR] 0.9-2.6). Among caregivers, 86 (65.2%) were biological mothers, 11 (8.3%) were biological fathers, and 35 (26.5%) were foster parents or extended family members. Low family SES was associated with communication concerns on the ASQ-3 (adjusted odds ratio [AOR] 3.04, 95% CI 1.08-8.57, P=0.04). Caregiver mental health concerns were associated with increased behavioural concerns on the CBCL (AOR 6.54, 95% CI 1.83-23.33, P=0.004) and higher scores on the ASQ-SE (AOR 7.78, 95% CI 2.38-25.38, P=0.001). Conclusion: Maltreated children with caregivers experiencing mental health issues are more likely to have heightened emotional and behavioural concerns. Those from low SES families are also at increased risk of language delay, affecting their communication.

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.

Facial impressions of niceness influence children's interpretations of peers' ambiguous behavior.

Children infer personality traits from faces when they are asked explicitly which face appears nice or mean. Less is known about how children use face-trait information implicitly to make behavioral evaluations. We used the Ambiguous Situations Protocol to explore how children use face-trait information to form interpretations of ambiguous situations when the behavior or intention of the target child was unclear. On each trial, children (N = 144, age range = 4-11.95 years; 74 girls, 67 boys, 3 gender not specified; 70% White, 10% other or mixed race, 5% Asian, 4% Black, 1% Indigenous, 9% not specified) viewed a child's face (previously rated high or low in niceness) before seeing the child's face embedded within an ambiguous scene (Scene Task) or hearing a vignette about a misbehavior done by that child (Misbehavior Task). Children described what was happening in each scene and indicated whether each misbehavior was done on purpose or by accident. Children also rated the behavior of each child and indicated whether the child would be a good friend. Facial niceness influenced children's interpretations of ambiguous behavior (Scene Task) by 4 years of age, and ambiguous intentions (Misbehavior Task) by 6 years. Our results suggest that the use of face-trait cues to form interpretations of ambiguous behavior emerges early in childhood, a bias that may lead to differential treatment for peers perceived with a high-nice face versus a low-nice face.

Growth and respiratory status at 3 years of age after moderate preterm, late preterm and early term births: the Japan Environment and Children's Study.

OBJECTIVE: To assess the association between gestational age at birth and the risk of growth failure and respiratory symptoms at 3 years of age. DESIGN: Cohort study using the Japan Environment and Children's Study database. PATIENTS: A total of 86 158 singleton infants born without physical abnormalities at 32-41 weeks of gestation were enrolled between January 2011 and March 2014. MAIN OUTCOME MEASURES: Growth failure (weight <10th percentile and height <10th percentile) and respiratory symptoms (asthma and wheezing) at 3 years of age. METHODS: Logistic regression analysis was used to evaluate the risk of growth failure and respiratory symptoms in the moderately preterm, late preterm and early term groups compared with the full-term group after adjusting for socioeconomic and perinatal factors. Multiple imputation was used to reduce the attrition bias related to missing data. RESULTS: The respective adjusted ORs (95% CI) of growth failure and respiratory symptoms for the moderate preterm, late preterm and early term groups compared with the full-term group were as follows: weight <10th percentile, 2.29 (1.48-3.54), 1.43 (1.24-1.71) and 1.20 (1.12-1.28); height <10th percentile, 2.34 (1.59-3.45), 1.42 (1.25-1.60) and 1.15 (1.09-1.22); asthma, 1.63 (1.06-2.50), 1.21 (1.04-1.41) and 1.16 (1.09-1.23); and wheezing, 1.39 (1.02-1.90), 1.37 (1.25-1.51) and 1.11 (1.06-1.17). CONCLUSION: Moderate preterm, late preterm and early term births were associated with a higher risk of growth failure and respiratory symptoms at 3 years of age than full-term births, with an inverse dose-response pattern.

Associations between prenatal caffeine exposure and child development: Longitudinal results from the Adolescent Brain Cognitive Development (ABCD) Study.

Objective: Though caffeine use during pregnancy is common, its longitudinal associations with child behavioral and physical health outcomes remain poorly understood. Here, we estimated associations between prenatal caffeine exposure, body mass index (BMI), and behavior as children enter adolescence. Method: Longitudinal data and caregiver-reported prenatal caffeine exposure were obtained from the ongoing Adolescent Brain and Cognitive Development (ABCD) SM Study, which recruited 11,875 children aged 9-11 years at baseline from 21 sites across the United States starting June 1, 2016. Prenatal caffeine exposure was analyzed as a 4-level categorical variable, and further group contrasts were used to characterize "any exposure" and "daily exposure" groups. Outcomes included psychopathology characteristics in children, sleep problems, and BMI. Potentially confounding covariates included familial (e.g., income, familial psychopathology), pregnancy (e.g., prenatal substance exposure), and child (e.g., caffeine use) variables. Results: Among 10,873 children (5,686 boys [52.3%]; mean [SD] age, 9.9 [0.6] years) with nonmissing prenatal caffeine exposure data, 6,560 (60%) were exposed to caffeine prenatally. Relative to no exposure, daily caffeine exposure was associated with higher child BMI (ß=0.08; FDR-corrected p=0.02), but was not associated with child behavior. Those exposed to two or more cups of caffeine daily (n=1,028) had greater sleep problems than those with lower/no exposure (ß>0.92; FDR-corrected p<0.04). Conclusion: Daily prenatal caffeine exposure is associated with heightened childhood BMI, and when used multiple times a day greater sleep problems even after accounting for potential confounds. Whether this relationship is a consequence of prenatal caffeine exposure or its correlated factors remains unknown.

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.

Development of full-body rhythmic synchronization in middle childhood.

Rhythmic entrainment is a fundamental aspect of musical behavior, but the skills required to accurately synchronize movement to the beat seem to develop over many years. Motion capture studies of corporeal synchronization have shown immature abilities to lock in to the beat in children before age 5, and reliable synchronization ability in adults without musical training; yet there is a lack of data on full-body synchronization skills between early childhood and adulthood. To document typical rhythmic synchronization during middle childhood, we used a wireless motion capture device to measure period- and phase-locking of full body movement to rhythm and metronome stimuli in 6 to 11 year-old children in comparison with adult data. Results show a gradual improvement with age; however children's performance did not reach adult levels by age 12, suggesting that these skills continue to develop during adolescence. Our results suggest that in the absence of specific music training, full-body rhythmic entrainment skills improve gradually during middle childhood, and provide metrics for examining the continued maturation of these skills during adolescence.

Adherence to the Mediterranean diet during pregnancy and behavioural problems at 4 years of age.

There is an increasing prevalence of psychological issues in childhood. Lifestyle factors during pregnancy, including maternal nutrition, have been linked to children's behavioural development. This study aims to assess the impact of adherence to the Mediterranean diet during pregnancy on the behavioural problems of children at the age of 4. A total of 231 mother-child pairs were assessed. Maternal adherence to the Mediterranean diet during pregnancy was estimated using a relative Mediterranean Diet Score (rMED). Behavioural outcomes were evaluated through the Child Behaviour Checklist 1½--5, Teacher's Report Form 1½-5, and Behaviour Rating Inventory of Executive Function-Preschool Version questionnaires. The results indicated that a higher rMED score during pregnancy was associated with a reduced probability of obtaining a clinical score for total problems (OR = 0.42; 95% IC from 0.21 to 0.85), including externalising (OR = 0.29; 95% IC from 0.14 to 0.62), attention problems (OR = 0.32; 95%IC from 0.15 to 0.70), attention-deficit/hyperactivity problems (OR = 0.36; 95% IC from 0.15 to 0.87), oppositional defiant problems (OR = 0.06; 95% IC from 0.06 to 0.75), and depressive problems (OR = 0.38; 95% IC from 0.15 to 0.96). This study highlights the importance of maternal diet, especially Mediterranean diet, during gestation for proper child development.

Proof of concept of the Universal Baby video innovation for early child development in Lima, Peru.

OBJECTIVE: Community-based video interventions offer an effective and potentially scalable early interaction coaching tool for caregivers living in low resource settings. We tested the Universal Baby (UB) video innovation; an early interaction coaching tool using video sourced and produced locally with early child development (ECD) expert supervision. METHODS: This proof-of-concept study enrolled 40 caregivers of children ages 10-18 months assigned to intervention and control groups by health establishments in Carabayllo, Lima, Peru. Mother/child dyads received 12 weekly group health education sessions with social support. Of those, 16 caregivers also received 6 UB videos featuring brain science education and local clips of responsive, reciprocal interaction, also known as "serve and return" interaction. Survey data assessed feasibility and acceptability of the intervention. We assessed improved quality of mother/child interaction using the Parenting Interactions with Children: Checklist of Observations Linked to Outcomes (PICCOLO). RESULTS: We found the program feasible. We successfully trained the local team to produce UB videos using locally-sourced footage and delivered the videos as part of a community-based intervention. We also found it to be acceptable in that participants enthusiastically received the UB videos, reporting they enjoyed being videotaped, and learned how to recognize and appropriately respond to their child's nuanced sounds and gestures. The median change in total PICCOLO scores favored the intervention group compared to the control group. CONCLUSIONS: UB offers great potential as a sustainable, potentially scalable, and culturally appropriate tool to promote equity for child development among young children living in low resource homes globally.

Building resilience in families experiencing homelessness through integration of health, parenting and child development programs.

Children who experience homelessness are vulnerable to mental health problems, developmental delays and lower academic achievement. Research suggests that parental health literacy, sensitive parenting behaviour and child self-regulation are modifiable mechanisms that might enhance children's resilience to adversities associated with homelessness, yet empirical evidence on implementing such interventions in shelter settings is limited. Through a coordinated academic-community partnership, this study aimed to examine the (1) feasibility of conducting an integrated health approach in shelter settings and (2) the effectiveness of separate interventions on child and parent outcomes. Results are discussed in terms of best practices in shelter settings and building resilience in families experiencing homelessness with young children.

Developmental Impacts of PANS/PANDAS and Inadequate Support for Children and Families.

This article examines the degree to which major domains of child development are affected by Pediatric Acute-Onset Neuropsychiatric Syndrome (PANS)/Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections (PANDAS). Using cross-sectional survey data collected with an international sample of parents who identify as having children with PANS/PANDAS (N = 402), this study analyzed parent-reported developmental impacts and access to treatment and adequate supports. Parents reported that PANS/PANDAS negatively impacted their children's development across all domains: Emotional Development (92% of children), Social Development (90%), Cognitive Development (86%), Academic Growth (86%), Identity Development (83%), Talent Development (73%) and Language Development (50%). In addition, developmental impacts were likely to be more severe for children whose parents reported a greater number of inadequate supports with parenting, school, extracurricular activities, and crisis situations. These results indicate that children and families affected by PANS/PANDAS need better support to maximize children's opportunities, at home, in school, and in their communities, to continue developing despite challenging neuropsychiatric symptoms.

Child developmental outcomes associated with postpartum depression and anxiety in low and middle-income countries: a systematic review.

AIMS: This systematic review aims to summarize the findings of empirical studies conducted in low- and middle-income countries (LMICs) examining the relationship between postpartum depression and anxiety, and child developmental outcomes measured at 24 months of child's age. METHODS: The study was performed as per PRISMA guidelines for a systematic review. EBESCO, ProQuest, PubMed, Science Direct, Google Scholar, and BMJ databases were examined, along with a forward and backward examination of the citations published. The New Ottawa scales (NOS) was used to assess the quality of the studies. The findings of the studies were integrated using a narrative synthesis approach. RESULTS: The systematic review revealed that there are 14 studies examining the impact of postpartum depression (n=14) and postpartum anxiety (n=2) across different domains of child development in LMICs. Studies varied regarding the severity and duration of maternal depression, the context and nature of evaluation, and motherinfant characteristics which are important to understand the association between postpartum depression and anxiety and infant development. Maternal depression is negatively associated with language development, socio-emotional and behavioural development while its association with motor and cognitive development is inconsistent. The impact of maternal anxiety on infant development was examined in two studies, and both have identified a negative association. However, the results of the current review need to be interpreted within the scope and limitations of the methodologies adopted by each study details of which are elaborated in the manuscript. CONCLUSION: Postpartum depression and anxiety can have a wide range of effects on child development. Therefore, periodic infant developmental assessments should become part of routine psychiatric evaluation. There is a need for uniform guidelines for conducting studies and reporting data related to postpartum mental health and child development.

Developmental milestones and daily living skills in individuals with Angelman syndrome.

BACKGROUND: Angelman syndrome (AS) is a neurodevelopmental disorder associated with severe global developmental delay. However, the ages at which different developmental skills are achieved in these individuals remain unclear. We seek to determine the probability and the age of acquisition of specific developmental milestones and daily living skills in individuals with AS across the different molecular subtypes, viz. class I deletion, class II deletion, uniparental disomy, imprinting defect, and UBE3A variants. METHODS: Caregivers participating in a longitudinal multicenter Angelman Syndrome Natural History Study completed a questionnaire regarding the age at which their children achieved specific developmental milestones and daily living skills. The Cox Proportional Hazard model was applied to analyze differences in the probability of achievement of skills at various ages among five molecular subtypes of AS. RESULTS: Almost all individuals, regardless of molecular subtype, were able to walk with support by five years of age. By age 15, those with a deletion had at least a 50% probability of acquiring 17 out of 30 skills compared to 25 out of 30 skills among those without a deletion. Overall, fine and gross motor skills such as holding and reaching for small objects, sitting, and walking with support were achieved within a fairly narrow range of ages, while toileting, feeding, and hygiene skills tend to have greater variability in the ages at which these skills were achieved. Those without a deletion had a higher probability (25-92%) of achieving daily living skills such as independently toileting and dressing compared to those with a deletion (0-13%). Across all molecular subtypes, there was a low probability of achieving independence in bathing and brushing teeth. CONCLUSION: Individuals with AS without a deletion are more likely to achieve developmental milestones and daily living skills at an earlier age than those with a deletion. Many individuals with AS are unable to achieve daily living skills necessary for independent self-care.
