Goat Infant Formula Feeding and Eczema (the GIraFFE Study)

To determine the relative risk of developing atopic dermatitis in infants fed a study formula based on whole goat milk compared to infants a study formula based on cow milk protein.

Maternal Omega-3 Supplementation to Reduce Bronchopulmonary Dysplasia

The aim of this randomized controlled trial is to determine whether docosahexaenoic acid (or DHA, an omega-3 lipid) supplementation in lactating mothers providing breast-milk to their infant born below 29 0/7 weeks of gestational age (GA) improves BPD-free survival at 36 weeks post-menstrual age (PMA). Half of participants will receive docosahexaenoic acid (DHA), an omega-3 lipid, while the other half will receive a placebo.

Musical Group Intervention for Children in Shelters

The aim of the study is to augment knowledge on interventions for children who live, or have lived, in shelters after exposure to domestic violence. Research questions concern the feasibility of a music group intervention for children. The experiences of children, caregivers, and professionals will be investigated. Additionally, outcomes concerning emotional reactivity, capacity for emotional regulation, quality of life, and psychological health will be evaluated.

Omega Tots Long Term Follow-up

This is a continuation study to the Omega Tots trial (NCT01576783). The purpose of this study is to follow-up with participants of the original study to determine the long-term effect a daily fatty acid dietary supplement taken during toddlerhood might have on children born preterm now that they are 8.5-10.5 years old.

Interventions in Mathematics and Cognitive Skills

The purpose of this study is to investigate neurocognitive mechanisms underlying response to intervention aimed at enhancing, and remediating weaknesses in, numerical skills in children, including those with mathematical learning disabilities (MLD).

Intergenerational Risk and Resilience of Rohingya in Displacement

The iRRRd study is an ongoing prospective longitudinal prenatal birth cohort study based in Cox's Bazar, Bangladesh. Between February 2023 and March 2024, 2,888 pregnant women were enrolled (approximately 80% Rohingya refugees living in camps, 20% Bangladeshi host community). The study aims to investigate (1) the effects of being conceived, gestated, born, and raised in contexts of conflict and forced displacement on child health and development; (2) the mechanisms underlying the intergenerational transmission of conflict and displacement trauma to offspring; and (3) the sources of heterogeneity in these associations across individual, social, biological, and contextual risk and protective factors. Five waves of data collection have been completed: prenatal recruitment (Wave 1), third-trimester follow-up for a subset of the sample (Wave 2), birth (Wave 3), 28 days postpartum (Wave 4), and 6 months postpartum (Wave 5, completed April 2025; N=2,526). This registration covers Wave 6, the 36-month follow-up, in which target children are assessed when they reach 36 months of age. Anticipated enrollment for this wave is approximately 2,200 mother-child dyads. Waves 1-5 were conducted without preregistration due to logistical and timing constraints inherent to launching large-scale research in a complex humanitarian context. Design and preparation for the 36-month wave began in June-July 2025, and field piloting of study procedures and measures began in September 2025. Follow-ups with children reaching 36 months of age began in late May 2026. The original planning estimate of March 2026 reflected the 36-month mark for the earliest-born children in the cohort (first births occurred in March 2023); the ±2-month eligibility window (Part 5) accommodated the modest delay to actual fieldwork start. Up to the first week of August, fieldwork progressed slowly with a smaller number of enumerators, as several measures were still being refined and modified based on ongoing piloting. We consider this wave officially launched once onboarding and training of an expanded group of data collectors is complete and the pace of follow-ups picks up with number of children turning 36 months of age. All field activities that predate this registration are considered piloting and have served to iron out remaining logistical, technical, and language issues, and to finalize decisions on tool and item selection. No data have been analyzed, with the exception of measures for which psychometric properties needed to be examined to inform modification and selection decisions.

Evaluating a Strengths-based Community-grounded Intervention

Structural inequities and historical underinvestment in marginalized communities create developmental contexts that constrain access to high-quality education, healthcare, stable housing, and other critical resources. This study evaluates effects of a strengths-based, community-led intervention on young children and their families, which aims to buffer structural inequities while recognizing families' strengths. Between ages 18-36 months, English- and Spanish-speaking families consented and were randomly assigned to the intervention group (ParentChild+) or the active control group (FamilyNutrition+). Each group received 92 contacts from a specialist matched with their demographics. For the intervention group, contact focused on supporting parents and children's early learning, and families received a book or toy each week; for the control group, contact focused on supporting child nutrition, and families received a small food voucher each week. The current study evaluates whether the intervention altered parents' mental health, children's early environments, and/or children's test performance and brain development.

China Children Eye Study

The primary objective of this multi-center, observational study is to establish the reference ranges of axial length in Chinese children and adolescents. 30,000 children aged 3-18 years were examined with cycloplegia to collect their ocular parameters and were all followed up for three years with annual visits.

Screen Time and Language Development in Toddlers Assessed With the Bayley-4

This cross-sectional study investigated whether caregiver-reported daily screen time is associated with language development in toddlers aged 12 to 42 months, measured with the Bayley-4. Receptive language was the primary outcome; expressive language, cognitive, and motor scaled scores were secondary. The study was conducted at the pediatric outpatient clinics of a tertiary care city hospital in Türkiye.

Impact of a Medical-Financial Partnership Intervention on Parent Mental Health, Perinatal Outcomes, and Child Developmental Risk

Poverty and financial stress are key social drivers of health and root causes of worse health beginning in pregnancy, continuing into childhood, and extending over the life course, but clinical tools to address the health impacts of poverty and financial stress are needed. This trial is of a multi-site medical-financial partnership intervention to examine its effect on parent, perinatal, and child outcomes, as well as health care utilization, and family financial and social risk. This pragmatic randomized clinical effectiveness trial will examine the impact of a clinic-based medical-financial partnership intervention beginning either 1) in the newborn period (Intervention Arm 1) or 2) during prenatal care (Intervention Arm 2) versus controls on parent, child, and family/household outcomes.

Gastrocnemius Tightness and Foot Pain in Children

Foot and leg pain among otherwise healthy children is a common reason for referral to our pediatric orthopaedics outpatient clinic. The pain is often intermittent and transient, but for some the pain is more dominating and has an impact on the child and families. Children grown and have normal anatomical variations such as in-toeing, out-toeing, hypermobility, flatfeet, knock knees etc. Assessing such normal variants is a major part of pediatric orthopaedic practice, and a common finding is a positive Silvferskiöld test, indicating gastrocnemius tightness. This is when dorsiflexion of the ankle is limited with extended knee, compared to flexed knee. We do not know if this is a more frequent finding among children with foot and leg pain. There is however evidence that adults with painful foot conditions often have gastrocnemius tightness. This project will investigate for gastrocnemius tightness in otherwise healthy children referred to our pediatric orthopaedic outpatient clinic with foot and leg pain, and compare results with a similar control group of children without pain. The aim is to investigate if there is an association, and how pain and tightness develops over time. The knowledge from this project will enable us to develop new treatment strategies to this patient group, where current evidence based recommendations are few.

Does Daily Physical Education Improve Motor Skill Development and Health-Related Physical Fitness in Preschool Children?

Background: During childhood, physical activity (PA) plays a fundamental role in motor development, as movement experiences during this critical period support the acquisition of both fine and gross motor skills (GMS) and foster an active lifestyle. This developmental phase, marked by regular engagement in PA and the progressive attainment of motor competence, has been consistently linked to a range of health benefits. Accordingly, early motor intervention programs have received considerable research attention for their demonstrated positive impact on children's motor skill development. Beyond such general approaches, more targeted strategies have also been explored, including programs aimed at increasing the amount of time devoted to PA within school settings. Prior studies have shown that incorporating structured exercise interventions-based on enjoyable, game-like activities-into the curriculum can significantly enhance children's fundamental motor skills. Method and Materials: A total of 258 preschool children (128 boys, 130 girls) were assigned to either a gender-balanced experimental group participating in an innovative, daily physical education program (EG; n=125) or a control group following the standard institutional curriculum (CG; n=133). The average age of participants was 6.07±0.42 years (EG: 6.05±0.43; CG: 6.10±0.40). In EG, participants had organized physical activity 5 days per week (3 days led by physical education specialists, 2 days by preschool teachers), with each session lasting approximately 30-40 minutes. The CG continued their usual routine with structured physical activity two times per week (1 day led by a specialist, 1 day by a teacher). The program was implemented over a period of six months. The Test of Gross Motor Development-2 (TGMD-2) and Body Coordination Test for Children (KTK) were used to assess GMS, while the PREFIT battery was used to assess health-related physical fitness. Aim: Тhe study aimed to empirically determine the effects of an experimental physical education program in preschool institutions on the development of motor skills and the improvement of health-related physical fitness in preschool-aged children.

Improving Maternal and Child Health Through Prenatal Fatty Acid Supplementation

The purpose of the study is to test whether nutritional supplementation during pregnancy is associated with 1) improved maternal health during pregnancy; 2) improved infant birth and neurodevelopmental outcomes, and 3) whether the association between nutritional supplementation during pregnancy and infant outcomes is partially mediated by reductions in maternal perceived stress and stress reactivity during pregnancy.

Embracing Morning BReakfast and Activity for Classroom Engagement

This experiment will test the effects of healthy breakfast and morning exercise on children's focus and classroom behavior. Food and exercise each influence child focus, but little is known about their effects on classroom behavior and less about their combined effects. For one week (Monday-Friday), 10 children will be randomly assigned to receive healthy breakfast and morning exercise, 10 assigned to only healthy breakfast, 10 to only exercise, and 10 to neither. After exercise and breakfast, study staff will assess how focused children are during class-time, ask them to complete puzzle-like tasks, and wear a helmet that measures brain blood flow

The Influence of Maternal Age, Employment Status, and Parenthood Status on Children's Cognitive Development

Research and theory tend to agree when suggesting that certain activities done by mothers have both immediate and delayed consequences for children's mental development in the first years of life. The everyday interaction between an infant and a caregiver can be broken down into many categories. There are data linking both of these types of interaction to the mental development of children. The study will focus on the extent to which maternal characteristics (age, employment status, parenthood status, and birth order of the child) influence the relation between maternal social and didactic caregiving and the social and mental development of children. Mother-infant interaction will be observed when the infants are 5 months old. When the children are 20 months old, measures of toddler function (e.g., ability to play and language development) and maternal behavior (e.g., encouragement of attention to the environment and I.Q.) will be obtained. When the children are 48 months old, researchers will measure preschooler psychosocial functioning (e.g., I.Q., cognitive and social competencies) and maternal behavior (e.g., "scaffolding"). Understanding the relation between children's experiences as infants, toddlers, and preschoolers and their eventual intellectual and social functioning is an essential part of normal developmental research.\<TAB\>

In Vitro Fertilization (IVF) and Prenatal Effects Independent of Genetics

This study examines how maternal stress during pregnancy affects infant brain and behavioral development, focusing on whether these effects are due to the prenatal environment or shared genes. By comparing IVF pregnancies using donor eggs/embryos (no shared genetics) with non-donor IVF pregnancies, the investigators aim to understand how stress influences the baby's development independent of genetic factors. Participants will complete questionnaires, provide blood samples, and take part in placenta and cord blood collection, fetal monitoring, and newborn brain activity assessments. Aim 1: The influence of maternal distress on perinatal neurobehavioral development. Hypotheses: Independent of IVF group status, higher maternal AL will be associated with higher 3rd trimester FHR reactivity, lower FHR variability, AND lower FHR-movement coupling Aim 2: Maternal distress affecting placenta gene methylation. Hypotheses: Independent of IVF group status, maternal AL will be associated with placenta differential DNA methylation in glucocorticoid-regulating genes (FKBP5 and HSD11B2), Aim 3: Maternal experiences associated with unique placenta transcriptomic profiles. Hypotheses: Independent of IVF group status, maternal AL and well-being each will be associated with unique placenta gene expression in pro-inflammatory genes

LOVING (Learning About Our Behavior is Valuable for Increasing Nurturing Relationships and Healthy Growth) RCT

The LOVING study is a randomized controlled trial designed to determine whether adaptations to an internationally recognized parenting program that enhances sensitive caregiving likewise improves sensitive caregiving in Singapore and, in turn, downstream child outcomes in emotional, behavioral, and cognitive development during the early childhood years. Research shows that sensitive caregiving is linked to secure relationships, decreased child mental health problems, better executive functioning, and potentially healthier body mass indices. The Video Feedback to Improve Positive Parenting and Sensitive Discipline (VIPP-SD) program is an internationally recognized home-based intervention designed to enhance sensitive caregiving. However, evidence demonstrating its efficacy in Asia remains extremely limited. Moreover, most previous evaluations have focused primarily on parenting or child mental health outcomes, with newer work only beginning to focus upon additional child outcomes. In this study, families with young children from median-income and below households living in Singapore will be randomly assigned to one of three groups. Some families will participate in a locally adapted version of the home-based VIPP-SD program that includes additional health-related scenarios (VIPP-SD-SingH). Other families will be assigned to CARE-SD, which was developed within the context of proof-of-concept research. CARE-SD is a standardized, digitally delivered parenting program using vicarious pre-rendered video examples and comments derived from the VIPP-SD program and does not include personalized feedback during home visits. Furthermore, CARE-SD includes health related scenarios and language and settings familiar to families living in Singapore. A third group will receive developmental information about children's learning and development (i.e., NeuroEducation Active Control). The programs are brief and are designed to be practical and accessible for families. Families participating in the study will take part in research visits that include questionnaires, observations of parent-child interaction, and activities designed to assess children's development. Laboratory visits will take place at IHDP (a collaborating institution) research facilities. Information collected in the study will help researchers better understand how parenting support programs influence children's emotional well-being, behavior, learning, and physical health. The results of this research may help inform the development of effective programs to support families and promote healthy child development.

Development, Sensory Profile, and Sleep Quality in Preschool Children Across Different Caregiving Models

This observational study aims to examine developmental status, sensory processing, and sleep quality in preschool children aged 3 to 6 years across different caregiving models. Children raised primarily by first-degree relatives, second-degree relatives, caregivers, or in daycare settings will be compared. Data will be collected using the Denver II Developmental Screening Test, the Dunn Sensory Profile, and the Tayside Children's Sleep Questionnaire. The study will also evaluate the relationships among developmental status, sensory processing, and sleep quality, and explore whether caregiving model is associated with differences in these outcomes.

Prospective Monitoring of Children Born in Haute Vienne From Uterine Life to Adulthood

The purpose of this survey is to collect data from intrauterine life until the age of 18 of children born in Haute Vienne. The interest to realize such survey is to find correlations and interactions that may exist between the events that occurred during intrauterine life and those that will occur after the birth of the child. The investigators will examine every aspect of these children's lives from the perspectives of health, social sciences and environmental health These are medical events (occurrence of disease, medication), but also socio-cultural for this child (living environment, exposure to possible contaminants, events in family history). This cohort aims to include 3000 children a year (whose parents consented to their inclusion), all born at Haute-Vienne.

Sharing Tales That Teach: Shared Picturebook Reading for Early Childhood Emotional and Cognitive Development

Sharing Tales That Teach is a randomised study of a shared picturebook reading programme for 4- to 5-year-old children and their primary caregivers. The study will test whether a caregiver-delivered, emotion-focused shared reading programme leads to greater improvements in children's emotion regulation than a standard dialogic shared reading programme. Emotion regulation refers to children's developing ability to understand, express and manage emotions in ways that support learning, relationships and wellbeing. These skills are closely linked with executive function, including children's ability to remember instructions, control impulses and shift flexibly between activities. Shared picturebook reading may provide a natural, low-cost way for caregivers to support these skills through everyday interaction. Families in the randomised part of the study will be allocated to one of two 8-week shared reading programmes. In the emotion-focused group, caregivers will receive training in strategies such as naming emotions, discussing why characters feel as they do, talking about consequences of emotions and modelling ways to manage feelings. In the comparison group, caregivers will receive training in standard dialogic picturebook reading strategies, such as naming, describing, sequencing and asking open questions, without an explicit focus on emotions or emotion regulation. Both groups will use the same picturebooks and will be asked to complete three shared reading sessions per week at home. The main hypothesis is that children in the emotion-focused shared reading group will show greater improvement in emotion regulation from baseline to 12-month follow-up than children in the standard dialogic shared reading group. The study will also examine whether the programme affects children's executive function, caregiver wellbeing and caregiver emotion regulation. Additional exploratory analyses will examine caregiver-child interaction processes and whether caregiver or child characteristics are associated with different intervention effects. The study will recruit caregiver-child dyads through state primary schools in Greater London. Children will complete age-appropriate tasks and caregivers will complete questionnaires at baseline and follow-up. A laboratory subsample may also complete additional behavioural, observational and neurophysiological assessments. The study is low risk, non-invasive and does not involve medical treatment.

Achieving Sustained Early Child Development Impacts at Scale: A Test in Kenya

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 in the absence of continued support. New ways to deliver effective ECD parenting interventions are sorely needed that are both low-cost to be potentially scalable, while also able to sustain impacts long-term. The rapid growth and low cost of mobile communications in LMIC settings presents a potentially promising solution to the competing problems of scalability and sustainability. Yet there is no rigorous research on mobile-health (mHealth) interventions for ECD outcomes in LMIC settings. Study investigators recently showed that an 8-month ECD parenting intervention featuring fortnightly group meetings delivered by Community Health Workers (CHWs) from Kenya's rural health care system significantly improved child cognitive, language, and socioemotional development as well as parenting practices, and a group-based delivery model was more cost-effective than previous ECD interventions. Yet it is still too expensive for scaling in a rural LMIC setting such as rural Kenya, particularly if interventions are needed that can be extended for longer periods of time to increase their ability to sustain impacts. This study will experimentally test a traditional in-person group-based delivery model for an ECD parenting intervention against an mHealth-based delivery model that partially substitutes remote delivery for in-person group meetings. The relative effectiveness and costs of this hybrid-delivery model will be assessed against a purely in-person group model, and the interventions will extend over two years to increase their ability to sustain changes in child outcomes longer-term. The evaluation design is a clustered Randomized Control Trial across 90 CHWs and their associated villages and 1200 households. The central hypothesis is that a hybrid ECD intervention will be lower cost, but remote delivery may be an inferior substitute for in-person visits, leaving open the question of the most cost-effective program.

Pregnancy and Early Neurodevelopmental Outcomes Following In Utero Lyme Disease Exposure

The purpose of this pilot study is to assess the feasibility of longitudinal neurodevelopmental evaluation of fetuses and infants exposed to Lyme disease in utero. Participants with Lyme disease or Post-Treatment Lyme Disease Syndrome (PTLDS) will be recruited during pregnancy. Pregnancies will be monitored and infant development will be assessed from birth until age 18 months.

Study Protocol: Cognitive, Emotional and Social Stimulation Programme for Low-SES Children.

Latin America and the Caribbean exhibit high rates of poverty and social exclusion, where a significant portion of the population faces challenges in meeting basic needs. This socioeconomic vulnerability exacerbates environmental violence and its associated consequences. Recognizing that contexts of poverty and social exclusion can adversely impact children's cognitive and emotional development, this research protocol aims to address these challenges. It proposes a cognitive and emotional stimulation program, complemented by an intervention targeting teachers and caregivers, grounded in neuroeducational principles. The overarching goal is to enhance children's cognitive and academic performance, thereby improving their long-term quality of life. Methods: A randomised controlled trial will be conducted to evaluate the efficacy of the intervention in an experimental group compared to a control group. A sample of more than 500 children from primary schools in disadvantaged contexts in Colombia A digital stimulation programme, designed and supervised by neuropsychologists, will be implemented within the classrooms and will be complemented with educational sessions in neuroeducation for teachers and caregivers, with weekly activities for 3 months. Three evaluations will be carried out: 1) pre-intervention, 2) post-intervention and 3) follow-up. During follow-up, the control group will receive the stimulation programme. Conclusions: The researchers anticipate a positive impact on the cognitive, emotional and academic performance of these children, providing evidence and support for the long-term creation of a tested and validated cognitive and emotional stimulation programme that could be integrated into the academic curriculum of educational centres in disadvantaged contexts.

Mother-infant Bonding During COVID-19

This study will assess whether the promotion of emotional exchange between mother and infant during the first four months of life improves primarily mother-child early relational health (ERH) and secondarily child neurodevelopmental and maternal mental health outcomes. In prior research on preterm infants, a similar intervention demonstrated increased quality of maternal caregiving behaviors and significant improvements in premature infants' neurodevelopment across multiple domains, including social-relatedness and attention problems. The goal of the emotional exchange intervention is to help mothers provide appropriate stimulation crucial for social, emotional, and neurobehavioral development, by helping the mother and child become attuned, or 'in sync', with each other. Measures of ERH, such as bonding, maternal sensitivity, and mother-child emotional connection will be compared between two groups: one receiving newborn parenting education and the other undergoing facilitated emotional exchange. Assessments will involve videos of mother-infant interactions during each intervention session and follow-up surveys conducted as part of a linked Institutional Review Board-approved study. Data collected in this study will contribute to understanding the underlying mechanisms of mother-infant interactions and their role in shaping optimal neurodevelopmental trajectories for infants and maternal mental health.
