Child Development

The objective of this research is to evaluate a mobile app-based intervention for parents of children in K-2nd grade designed that guides them in how to have productive conversations about race with their children. This study will recruit a national sample of parents and their K-2nd grade children. The impact of the intervention is tested using a wait-list controlled trial design. Outcomes include prosocial behaviors and indicators of emotional well-being.

Extreme heat exposure is an escalating global public health concern, with climate change driving increases in the frequency, duration, and intensity of heat events. Projections indicate substantial increases in heat-related morbidity and mortality in the coming decades, including among children and youth, who are increasingly recognized as a physiologically vulnerable population. The purpose of this project is to evaluate the effectiveness of commonly used heat-mitigation strategies, specifically midday access daylong electric fan use, in reducing physiological strain and maintaining cognitive function, perceptual comfort, and psychological well-being in children and youth exposed to prolonged indoor heat. The study also aims to determine whether these strategies provide comparable protection in children and youth relative to young adults. Participants will complete four sessions under the same environmental conditions (31°C and 36°C), with each temperature completed twice: once with continuous electric fan use and once without fan use. The four sessions therefore consist of: (1) 31°C without fan use; (2) 31°C with fan use; (3) 36°C without fan use; and (4) 36°C with fan use.

Healthy Adaptation to Pregnancy, Postpartum and Parenthood (HAP3) The HAP3 study is evaluating a new digital support program for pregnant women and their partners. The program includes the HAP3 Family App, which provides information and practical tools on healthy eating, physical activity, sleep, emotional well-being, pregnancy and postpartum care, healthy weight management, parenting, and child development. Researchers want to find out whether the app is easy to use, acceptable to families, and practical to implement during pregnancy and after birth. The study will also explore whether using the app may help improve parents' mental well-being, healthy lifestyle habits, weight management, and early child development. Participants will be randomly assigned to one of two groups. One group will receive access to the full HAP3 Family App, personalized coaching by phone or video call, and supportive messages. The other group will receive usual care and use the app only to complete study questionnaires. The study will follow families from pregnancy until six months after birth. Participants will complete questionnaires about their health, well-being, and parenting experiences. Those using the full app will also be asked to complete brief in-app check-ins about mood, sleep, stress, and daily habits. The HAP3 intervention is not a medical treatment and involves minimal risk. Potential benefits include increased awareness of health behaviors, access to evidence-based information, and support during the transition to parenthood. The study is being conducted by researchers from KU Leuven (Belgium), Vrije Universiteit Amsterdam (Netherlands), and Technische Universität Dresden (Germany) as part of the European HAP3 project.

Families of children with neurodevelopmental differences (NDDs) experience disproportionately high levels of parenting stress and mental health difficulties, including elevated depression, anxiety, and caregiver burden. These challenges are often compounded by increased caregiving demands, system navigation stress, and limited access to timely, tailored mental health supports. Parental mental health plays a critical role in family functioning and child outcomes; however, existing services for families of children with NDDs are frequently fragmented, inaccessible, or focused primarily on child behavior rather than caregiver well-being. As a result, many caregivers experience unmet mental health needs that persist throughout early and middle childhood. To address this gap, our team developed BEAM (Building Emotional Awareness and Mental Health), an app-based parenting and mental health intervention that integrates psychoeducation, peer support, progress monitoring, and coached support. Clinical trials evaluating BEAM with parents of young children have demonstrated promising improvements in parental depression, anxiety, and parenting stress, as well as reductions in harsh parenting practices. Building on this evidence base, the current trial examines the implementation and outcomes of BEAM delivered as-is to families of children with NDDs (BEAM-NDD), without content adaptation, to evaluate its feasibility and effectiveness within this high-need population. This trial uses a single-arm pre-post design to evaluate BEAM-NDD among parents and caregivers of children with diagnosed or suspected neurodevelopmental differences. Primary aims are to (1) assess feasibility and acceptability of BEAM-NDD, including recruitment, retention, engagement, satisfaction, and perceived unmet needs; (2) examine changes in caregiver mental health and parenting outcomes following program participation; and (3) explore individual differences in engagement and outcomes to identify for whom BEAM-NDD may be more or less effective. Participants will complete a 12-week intervention delivered through the BEAM app, consisting of weekly parenting and mental health videos, progress tracking, a moderated peer forum, and optional peer-coaching support. Assessments will be completed at baseline prior to program initiation (T1), immediately post-intervention (T2), and at follow-up (T3). By evaluating BEAM-NDD within real-world service contexts, this trial aims to determine whether an existing evidence-based digital parenting and mental health intervention can support caregiver well-being among families of children with NDDs without requiring adaptation. Findings will inform the scalability and sustainability of BEAM-NDD as an accessible mental health support for families facing long waitlists, limited specialized services, or geographic barriers to care.

The main objective of this study is to test the efficacy of an intervention package (dietary, physical and lifestyle modification) during pregnancy in improving the clinical outcomes of mother-infant dyads.

Generation Victoria (GenV) is a longitudinal, population-based study of Victorian children and their parents that will bring together data on a wide range of conditions ,exposures and outcomes. GenV blends study-collected, study-enhanced and linked data. It will be multi-purpose, supporting observational, interventional, health services and policy research within the same cohort. It is designed to address physical, mental and social issues experienced during childhood, as well as the antecedents of a wide range of diseases of ageing. It seeks to generate translatable evidence (prediction, prevention, treatments, services) to improve future wellbeing and reduce the future disease burden of children and adults. The GenV Cohort 2020s is open to all children born over a two-year period, and their parents, residing in the state of Victoria Australia. The GenV Cohort 2020s is preceded by an Advance Cohort of children born between 5 Dec 2020 and 3 October 2021, and their parents. This comprises all families recruited at GenV's Vanguard hospital (Joan Kirner Women's and Children's) and at birthing hospitals throughout Victoria as GenV scaled up to commence recruiting for the GenV Cohort 2020s. The Advance Cohort have ongoing and full participation in GenV for their lifetime unless they withdraw but may have less complete data and biosamples.

Little is known about how children and youth regulate body temperature during exercise across different environmental temperatures compared with young adults, including whether differences in whole-body heat exchange contribute to their responses. The goal of this clinical trial is to determine how ambient temperature affects thermoregulation during exercise in boys and girls aged 9-16 years compared with young adult men and women aged 20-25 years. Participants will complete four study visits at ambient temperatures of 22°C (Celsius; 72°F, Fahrenheit), 26°C (79°F), 31°C (88°F), and 36°C (97°F), while exercising at the same moderate-intensity metabolic heat production of 160 W/m² (W = watts, m = meters). During each visit, participants will complete four 15-minute periods of exercise (exercise bouts 1, 2, 3 and 4 respectively) separated by 15-minute rest periods. Testing will be performed in a whole-body air calorimeter, a specialized chamber that precisely measures heat lost through evaporation and dry heat exchange and the amount of heat stored in the body. These measurements, together with core temperature and heart rate, will allow researchers to determine how increasing ambient temperature affects the body's ability to lose heat and whether these responses differ between children and youth and young adults.

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

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).

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.

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.

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

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.

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.

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.

Early evaluation of prewriting skills is important, as prewriting skills set the stage for later learning of the fine motor and visual motor skills needed for writing. Evaluation of prewriting skills allows for the identification of those children who struggle with these tasks so that early intervention might address these foundational skills before academic demands become more challenging. However, current prewriting skill assessments are limited to pencil-and-paper assessments that require an evaluator to score the drawn shapes. Manual scoring is time consuming, can be subjective, and limit the ability to capture subtle changes in performance. We have developed an assessment on a tablet to assess prewriting skills in children. The preliminary testing of the assessment is published in a paper (https://pubmed.ncbi.nlm.nih.gov/35417278/). We are now working on developing an online version of the assessment that will allow offsite data collection and will automate the analysis on the website so that the results can be automatically generated for the clinician or educator who wants to use this with the children they work with.

The purpose of this clinical trial is to learn about the effects of a nursing support program designed for families of children aged 1 to 3 years who have undergone heart surgery. This program aims to improve parents' caregiving skills and support the healthy growth of their children. The primary questions the study aims to answer are: Does the nursing program positively affect the physical growth of children, such as their height and weight? Does the program improve children's scores on general development tests (Denver II)? Do parents' attitudes toward child feeding and their confidence in parenting skills increase? Researchers will divide participants into two groups: Experimental Group: Families who participate in the nursing education program and receive an informative booklet. Control Group: Families who only receive an informative booklet and continue with routine hospital follow-ups. The researchers will compare these two groups to see if participating in the nursing program leads to better results for the children's development and the families' skills. Participants will be asked to: Attend 5 different education and counseling sessions, starting one week before surgery and continuing until the child reaches 1 year of follow-up. Meet with the researcher at specific intervals (at 1, 2, 3, 6, 9, and 12 months) for one year to monitor the child's development (height, weight, head circumference) and skills. Complete surveys regarding child feeding attitudes and parenting skills at the 6th and 12th month follow-ups.

The goal of this clinical trial is to learn if a conditional social transfer works to improve rates of complementary breastfeeding. It will also learn about the impacts of social transfers on maternal and child health and development. The main questions it aims to answer are: * Does the social transfer increase complementary breastfeeding rates at 24-months postpartum? * Does the social transfer increase complementary breastfeeding duration? * Does the social transfer impact child health and development? * Does the social transfer impact maternal physical and mental health? Researchers will compare a conditional social transfer to a control group that only receives education about breastfeeding recommendations to see if a conditional social transfers works to increase complementary breastfeeding. Participants will: Receive a pamphlet explaining the current recommendations of breastfeeding Receive instructions that if they meet the recommendation to breastfeed until 24-months postpartum they receive a social transfer or receive no additional information Complete home visits at 12- and 24-months postpartum Complete detailed questionnaire

A significant number of children are abused or neglected every year. This exposure is associated with short- and long-term consequences for their mental and somatic health. In France, 308,000 minors are benefiting from at least one child protective service or measure. There are few data on the health status of this population, and how it is evolving. Against this backdrop, interventions are needed to address the many needs of these children early and comprehensively, both in the short and long term. The PEGASE program, funded by the French government under Article 51, aims to ensure adequate medical follow-up - both somatic and psychiatric - for children taken into care by child protective services (CPS). An evaluation of the program's effectiveness and efficiency is needed to inform public decision-making on the appropriateness of extending it to all children under CPS's care. This requires the creation of a control cohort of children followed by CPS but not benefiting from the PEGASE program, the ESPER cohort (Prospective cohort study of protected children), which will enable us to carry out a comparative evaluation of the PEGASE program, as well as to provide information on the health of children followed by the CPS at the time of their placement and its evolution over time, data which are rare in France. The main objective is to evaluate the effectiveness of the PEGASE program on the evolution of the mental health of children followed by the CPS after 2 years of follow-up.

This study aims to evaluate the feasibility and efficacy of the Building Regulation in Dual Generations (BRIDGE) program for caregivers with significant mental health concerns and preschool and young children (3-7 years old) with elevated attention and/or behavior problems. The BRIDGE program focuses on supporting parental psychological distress and improving young children's self-regulation (SR), thereby reducing their attention and behavior problems. The long-term goal of this work is to improve family well-being and social-emotional development for young children by implementing an accessible and scalable dual-regulation program. The investigators will achieve this through the following key objectives: 1. Assess the feasibility and accessibility of BRIDGE for preschool and young children (3-7 years old) with significant attention and behavior programs through questionnaires asking about attendance, satisfaction, and unmet needs. 2. Examine the efficacy of BRIDGE compared to control group at improving maternal mental health and child attention and behavioral difficulties in young children (primary outcomes). The investigators will also examine parenting stress (secondary outcome). 3. Identify predictors of academic readiness skills in preschool and young children. The investigators hypothesize that an increase in parental and child emotion-regulation skills and reduced attention, as well as behavioral problems, will lead to increased pre-academic skills in children.

The goal of this observational study is to analyze early development in infants and young children from a biopsychosocial perspective, with a particular focus on cognitive, language, motor, social-emotional, and adaptive functioning during the first years of life. The study will include infants and young children from 16 days of age up to 42 months of age, assessed during a single diagnostic session conducted by qualified specialists. The developmental assessment will include standardized diagnostic tasks and direct observation of behavior in the form of play and natural interaction, carried out in the presence of a parent or legal guardian. In addition, information regarding the child's everyday functioning will be collected from parents or caregivers using standardized questionnaires, including data on social-emotional competencies, communication, and adaptive skills. The main research questions addressed by this study are: What is the developmental profile of infants and young children in the first years of life? What relationships exist between different domains of early development within a biopsychosocial model of child functioning? Can specific developmental patterns be identified that indicate an increased risk of developmental difficulties in early childhood? How does age differentiate the structure and variability of developmental functioning across assessed domains? The study is non-invasive and observational in nature. Data will be analyzed exclusively in aggregated form and will contribute to a better understanding of early child development as well as to the development of norms and tools supporting early diagnosis and developmental intervention.

The goal of this observational study is to investigate perinatal, cognitive, linguistic and social-emotional correlates of developmental delays of preschool children. The study group consist of minimal 500 children between 3 and 6 years of age who will be examined by qualified diagnosticians. Participants will be evaluated with tasks related to the studied variables: cognitive functioning, linguistic skills and social-emotional functioning. Furthermore informations regarding social-emotional functioning of children, will be collected from parents. The main questions it aims to answer are: 1. Is there a relationship between perinatal factors and risk of occurrence of developmental delay disorder? 2. Is there a specific pattern of cognitive functioning in preschool children with indicated developmental delay disorder? 3. Is there a specific pattern of social-emotional functioning in preschool children with indicated developmental delay disorder? 4. Do gender and age moderates specific patterns of cognitive and socialemotional functioning in the studied groups? Researchers will compare the following groups of children between 3 and 6 years old: 1. With perinatal risks factors 2. With developmental delay disorder: 1. children with early intervention 2. children with delayed speech development 3. Control group

Early childhood is a critical period, laying the foundation for future growth and deveopment. This foundational period has an outsized effect, impacting health, well-being and achievement across one's lifespan. The U.S. lacks a cohesive early childhood system to support families with young children ages 0-5. The goal of this randomized controlled trial(RCT) is to test if community-based support via community health workers(CHWs) improves social and health services utilization, and child development. Furthermore, the trial will examine if income support enhances the impact of a CHW integrated system. Participants are English and Spanish speaking families with healthy newborns. This RCT was designed based on family priorities, community capacity and needs in a collective impact model. This trial is anchored at a university based children's hospital and involves many partners: families, county health, county leadership, a leading early childhood non-profit organization, the county's Medicaid managed care organization.

The association between nutrition in early life and its long-term health consequences has long been known. However, there is a scarcity of scientific evidence on how nutritional status affects child growth and development in remote, rural agro-pastoral communities with distinct dietary intake habits, geographical location, socio-economic status, and cultures.

This study will test whether a structured motor-focused exercise program can improve both brain function and gross motor skills in preschool children. About 110 children aged 4 to 6 years will be recruited from kindergartens in Changsha, China. Classes will be randomly assigned to receive either (1) motor-focused physical education three times per week for 16 weeks, or (2) ordinary physical education of the same frequency and duration. The motor-focused program includes playful, game-based activities designed to strengthen locomotor skills (such as running and hopping) and object-control skills (such as throwing and catching). The main outcome will be changes in children's gross motor skills, measured with a standardized motor test (TGMD-3). Brain activity will also be assessed using portable electroencephalography (EEG) during rest and simple tasks related to attention and memory. Parents and teachers will complete short questionnaires about children's behavior and executive function. The results of this study may provide new insights into how physical education influences both movement skills and brain development in early childhood.
