Efficacy of Electric Fans in Children During Heat Waves

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.

Play-Based Motor Training in Children Aged 7-10 Years

This randomized controlled study evaluated the effects of an 8-week structured play-based motor training program on motor competence in children (boys and girls) aged 7-10 years. Eighty eligible participants (40 boys and 40 girls) were individually randomized in a 1:1 ratio to an intervention group or a usual physical-education control group. The intervention consisted of 24 play-based motor-training sessions delivered three times per week for 60 minutes, whereas the control group continued usual physical education twice per week for 40 minutes. The primary outcome was motor competence assessed using the MABC-2 total score. Cognitive test performance measured using the Kay Cognitive-Diagnostic Test and parent-rated executive-function difficulties measured using the BRIEF Parent Form were exploratory secondary outcomes. Posttest outcomes were compared between groups using ANCOVA with the corresponding baseline score as a covariate. This study record was created retrospectively after completion of the study.

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\>

Effects of Animal Fun Program in Children With DCD.

This randomized clinical trial investigates the effects of animal fun program on motor skills in children with developmental coordination disorder. The study involves 40 children from normal school age group 6 to 12 year old, who will be randomly assigned to one of the two groups for a six-week intervention period. Key performance outcomes -body management truck control, locomotion, balance ,object control,body sequencing social and emotional control will be assessed both before and after the intervention.This study aims to address this gap by evaluating the effects of the Animal Fun Program on both fine and gross motor activity levels in children diagnosed with DCD. By examining objective motor outcomes and child engagement, the study seeks to determine whether this novel, enjoyable intervention can enhance traditional therapy methods, leading to improved motor development and overall quality of life for children with DCD. Data will be analyzed through SPSS version 27.00.

Factors Affecting Newborn Body Composition and Later Health in Helsinki Birth Cohort 2018-2022

In Helsinki Birth Cohort 2018-2022 a large, longitudinal and well-phenotyped birth cohort of infants and their parents will be established. Mothers, fathers/spouses and their children in Helsinki and Uusimaa Hospital District are recruited in the study and newborn composition of the children born in Helsinki Women's Hospital will be measured. Data on maternal and paternal diet quality, physical activity and depression during and after pregnancy will be collected and data from the hospital and national registers will be collected. Health of offspring and parents will be followed during their later life.

The Effect of In-utero Exposure to Metformin in 5-11 Year Old Offspring of Mothers in the MiTy Trial

The incidence of diabetes in pregnancy is rising, with rates of 1 in 7 pregnancies globally. Metformin is used for type 2 diabetes (T2DM) outside of pregnancy and is now increasingly prescribed during pregnancy. There are some concerns as metformin crosses the placenta and effects on offspring exposed during pregnancy are unknown. Animal and human evidence indicate that metformin may create an atypical in-utero environment similar to under-nutrition which has been associated with adult obesity. This is supported by studies in children of mothers treated with metformin in other populations where an increase in childhood obesity was found at 4-9 years of age. We now have evidence from the MiTy trial, that offspring of metformin-exposed women with T2DM have less large infants and are less adipose at birth, but are also more likely to be small for gestational age (SGA). These effects could lead to benefit or harm in the long-term. Offspring of MiTy mothers are currently being followed up to 2 years. Given that long-term effects may not be evident until 5 years of age, it is imperative to follow these children longer. Goals/Research Aims:To determine whether in-utero exposure to metformin, in offspring of women with T2DM, is beneficial or harmful in the long-term. Research Questions: 1. In offspring of women with T2DM, how does treatment with metformin during pregnancy affect a) adiposity b) growth over time c) metabolic syndrome d) cognitive and behavioral measures:2. What factors predict altered childhood adiposity and insulin resistance in these offspring? Primary Outcome: Body mass index (BMI) z-score. Secondary Outcomes: 1) other measures of adiposity (i.e. skinfolds, 2) growth over time 3) measures of insulin resistance 4) adipocytokines 5)neurodevelopment Expected Outcomes Given these increasing concerns, this study will inform the best treatment for pregnant mothers with diabetes by studying the long-term outcomes of children exposed to metformin during pregnancy.

Healthy Adaptation to Pregnancy, Postpartum and Parenthood

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.

Study of the Effects of Soy Exposure in Early Life on Bone Development and Gut Microbiota

In this project, the investigators aim to investigate the effects of soy consumption at early life on the development of gut microbiota and bone growth. The hypothesis to be tested is that early-life exposure to soy optimize bone growth via the alteration of gut microbiota composition. Clinical samples from mother-child pairs recruited into the SMART Gen Hong Kong cohort will be used to examine the association between maternal soy intake with infant gut microbiota and child's bone development. Primary outcome: Bone mineral density; dynamic bone formation parameters; messenger ribonucleic acid (mRNA) expression of bone markers. Secondary outcome: Gut microbiome profile; metabolomic profile in serum, urine or feces; correlation between soy-induced gut microbiota or metabolites and bone growth. The investigators expect that early life exposure to soy will improve bone growth via gut microbiota and provide scientific evidences for the use of soy preparation in early life as a preventive measure for optimizing bone health.

Generation Victoria Cohort 2020s: A Statewide Longitudinal Cohort Study of Victorian Children and Their Parents

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.

Single-Session Psychotherapy for Young Kids Through Patient Engagement Techniques

The goal of this clinical trial is to compare outcomes between participants in the single-session psychotherapy for young kids (SPYKids) conditions and participants in the services as usual (SAU) condition. The main questions it aims to answer are: * What is the feasibility and acceptability of SPYKids compared to services as usual? * What are the changes in child mental health between the SPYKids group compared with the SAU group? Participants will * Fill out questionnaires at baseline, immediately post-program, approximately one month after the baseline assessment, and three months after the baseline assessment * Meet with a parent coach in a virtual 90-minute session to discuss coping strategies relevant to their identified concerns Researchers will compare participants in the SPYKids group with participants in the Services as Usual group to see if there are changes in child well-being, parent well-being, and parent self-efficacy.

School-Based Mental Health Effectiveness Study

This study involves efforts to advance the science of prevention in early childhood mental health in low-resource communities. Investigators will assess the effectiveness, practical implementation strategies, and underlying mechanisms of the evidence-based intervention, ParentCorps-Professional Development, in urban and rural Uganda. Two implementation approaches, with and without the teacher stress management package, T-Wellness, will be compared for efficacy.

A Study to Compare the Long-term Outcomes After Two Different Anaesthetics

There is considerable evidence that most general anaesthetics modulate brain development in animal studies. The impact is greater with longer durations of exposure and in younger animals. There is great controversy over whether or not these animal data are relevant to human clinical scenarios. The changes seen in preclinical studies are greatest with GABA agonists and NMDA antagonists such as volatile anaesthetics (eg sevoflurane), propofol, midazolam, ketamine, and nitrous oxide. There is less evidence for an effect with opioid (such as remifentanil) or with alpha 2 agonists (such as dexmedetomidine). Some, but not all, human cohort studies show an association between exposure to anaesthesia in infancy or early childhood and later changes in cognitive tests, school performance or risk of developing neurodevelopmental disorders. The evidence is weak due to possible confounding. A recent well designed cohort study (the PANDA study) comparing young children that had hernia repair to their siblings found no evidence for a difference in a range of detailed neuropsychological tests. In that study most children were exposed to up to two hours of anaesthesia. The only trial (the GAS trial) has compared children having hernia repair under regional or general anesthesia and has found no evidence for a difference in neurodevelopment when tested at two years of age. The GAS and PANDA studies confirm the animal data that short exposure is unlikely to cause any neurodevelopmental impact. The impact of longer exposures is still unknown. In humans the strongest evidence for an association between surgery and poor neurodevelopmental outcome is in infants having major surgery. However, this is also the group where confounding is most likely. The aim of our study is to see if a new combination of anaesthetic drugs results in a better long-term developmental outcome than the current standard of care for children having anaesthesia expected to last 2 hours or longer. Children will be randomised to receive either a low dose sevoflurane/remifentanil/dexmedetomidine or standard dose sevoflurane anaesthetic. They will receive a neurodevelopmental assessment at 3 years of age to assess global cognitive function.

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.
