Physical activity, sedentary behaviour, and childhood asthma: a European collaborative analysis.

Objectives: To investigate the associations of physical activity (PA) and sedentary behaviour in early childhood with asthma and reduced lung function in later childhood within a large collaborative study.

Design: Pooling of longitudinal data from collaborating birth cohorts using meta-analysis of separate cohort-specific estimates and analysis of individual participant data of all cohorts combined.

Setting: Children aged 0-18 years from 26 European birth cohorts.

[This corrects the article DOI: 10.1371/journal.pone.

The cross-sectional association of parental psychosocial status with children's Body Mass Index z-score and the mediating role of children's energy balance behaviors - the ABCD Study.

Objective: Investigate the cross-sectional association between the psychosocial status of mothers and fathers and the BMI z-scores of their 10 to 12-year-old children. Explore whether this association is mediated by children's diet, physical activity, screen time and sleep. Analyze the moderating effect of the educational levels of both the mother and father on the association.

Long-term cardiometabolic health in people born after assisted reproductive technology: a multi-cohort analysis.

Aims: To examine associations of assisted reproductive technology (ART) conception (vs. natural conception: NC) with offspring cardiometabolic health outcomes and whether these differ with age.

Methods And Results: Differences in systolic (SBP) and diastolic blood pressure (DBP), heart rate (HR), lipids, and hyperglycaemic/insulin resistance markers were examined using multiple linear regression models in 14 population-based birth cohorts in Europe, Australia, and Singapore, and results were combined using meta-analysis.

[Digital media use and sleep of adolescents: the effect of rules at home].

Objective: To test whether parental rules regarding the amount of digital media use is associated with the sleep of Dutch adolescents, and whether this is indirectly due to lower digital media use.

Design: Cross-sectional study METHOD: Adolescents and their parents of the Amsterdam Born Children and their Development (ABCD) study completed questionnaires in 2019 at the age of 15-16 years (n=1369; 56% girls). Parents and adolescents reported whether there are rules regarding the amount of digital media use.

Parental Discontent with Infant Sleep During the First Two Years of Life.

Background: Problematic sleep in infants can have a high impact on families. We examined parental discontent with infant sleep in the first six months of life and parent-perceived problematic sleep during the second year of life.

Methods: We used Sarphati Cohort data of 1471 children.

The need of having a plan in excessive infant crying - A qualitative study of parents' experiences of healthcare support.

Aim: Excessive infant crying increases parents' concerns regarding their infant's health and the burden of parenting. We aimed to gain insight into the healthcare support needs of parents with excessively crying infants.

Methods: An exploratory qualitative study was conducted in the Netherlands.

Exposure to natural environments during pregnancy and birth outcomes in 11 European birth cohorts.

Research suggests that maternal exposure to natural environments (i.e., green and blue spaces) promotes healthy fetal growth.

Association of Assisted Reproductive Technology With Offspring Growth and Adiposity From Infancy to Early Adulthood.

Importance: People conceived using assisted reproductive technology (ART) make up an increasing proportion of the world's population.

Objective: To investigate the association of ART conception with offspring growth and adiposity from infancy to early adulthood in a large multicohort study.

Design, Setting, And Participants: This cohort study used a prespecified coordinated analysis across 26 European, Asia-Pacific, and North American population-based cohort studies that included people born between 1984 and 2018, with mean ages at assessment of growth and adiposity outcomes from 0.

Gestational sleep deprivation is associated with higher offspring body mass index and blood pressure.

Study Objectives: The objective of this study was to evaluate the association between gestational sleep deprivation and childhood adiposity and cardiometabolic profile.

Methods: Data were used from two population-based birth cohorts (Rhea study and Amsterdam Born Children and their Development study). A total of 3,608 pregnant women and their children were followed up until the age of 11 years.

Potential determinants during 'the first 1000 days of life' of sleep problems in school-aged children.

Study Objectives: Early life determinants of sleep problems are mostly unknown. The first 1000 days of life (ie, the time between conception and a child's second birthday) is a period where the foundations for optimum health, growth and neurodevelopment are established. The aim of this explorative study is to identify potential early life determinants of sleep problems at age 7-8 years.

Sleep during Infancy and Associations with Childhood Body Composition: A Systematic Review and Narrative Synthesis.

Prevention of childhood overweight should start as early as possible preferably in "the first 1000 days of life." Sleep is one of the modifiable health behaviors during this age period, besides dietary intake and physical activity. The aim of this systematic review is to summarize the existing literature regarding the association between sleep during infancy (age ≤24 months) and body composition measures during childhood (age ≤12 years).

Does early onset asthma increase childhood obesity risk? A pooled analysis of 16 European cohorts.

The parallel epidemics of childhood asthma and obesity over the past few decades have spurred research into obesity as a risk factor for asthma. However, little is known regarding the role of asthma in obesity incidence. We examined whether early-onset asthma and related phenotypes are associated with the risk of developing obesity in childhood.

Mother's education and offspring asthma risk in 10 European cohort studies.

Highly prevalent and typically beginning in childhood, asthma is a burdensome disease, yet the risk factors for this condition are not clarified. To enhance understanding, this study assessed the cohort-specific and pooled risk of maternal education on asthma in children aged 3-8 across 10 European countries. Data on 47,099 children were obtained from prospective birth cohort studies across 10 European countries.

A Study on Mediation by Offspring BMI in the Association between Maternal Obesity and Child Respiratory Outcomes in the Amsterdam Born and Their Development Study Cohort.

Background: A causal relationship between maternal obesity and offspring asthma is hypothesized to begin during early development, but no underlying mechanism for the found association is identified. We quantitatively examined mediation by offspring body mass index (BMI) in the association of maternal pre-pregnancy BMI on risk of asthma and wheezing during the first 7-8 years of life in a large Amsterdam born birth cohort.

Methods: For 3185 mother-child pairs, mothers reported maternal pre-pregnancy BMI and offspring outcomes "ever being diagnosed with asthma" and "wheezing in the past 12 months" on questionnaires.

Drug Dosing and Pharmacokinetics in Children With Obesity: A Systematic Review.

Importance: Obesity affects nearly one-sixth of US children and results in alterations to body composition and physiology that can affect drug disposition, possibly leading to therapeutic failure or toxic side effects. The depth of available literature regarding obesity's effect on drug safety, pharmacokinetics, and dosing in obese children is unknown.

Objective: To perform a systematic literature review describing the current evidence of the effect of obesity on drug disposition in children.
