Secular trends in physical growth, biological maturation, and intelligence in children and adolescents born between 1978 and 1993
Introduction: Human physical growth, biological maturation, and intelligence have been documented as increasing for over 100 years. Comparing the timing of secular trends in these characteristics could provide insight into what underlies them. However, they have not been examined in parallel in the same cohort during different developmental phases. Thus, the aim of this study was to examine secular trends in body height, weight, and head circumfe…
Raised in conditions of psychosocial deprivation
Institutionalization is associated with a substantial developmental risk. Ethical constraints make it challenging to obtain robust empirical data on the effects of deprivation. Furthermore, because institutionalized children often face global deprivation, assessing the specific effects of psychosocial deprivation becomes difficult. Moreover, limited research exists on factors explaining interindividual differences. To investigate developmental ou…
Death from Failed Protection? An Evolutionary-Developmental Theory of Sudden Infant Death Syndrome
Sudden infant death syndrome (SIDS) has been mainly described from a risk perspective, with a focus on endogenous, exogenous, and temporal risk factors that can interact to facilitate lethal outcomes. Here we discuss the limitations that this risk-based paradigm may have, using two of the major risk factors for SIDS, prone sleep position and bed-sharing, as examples. Based on a multipronged theoretical model encompassing evolutionary theory, deve…
Secular trends in motor performance in Swiss children and adolescents from 1983 to 2018
Introduction: Environmental changes, including globalization, urbanization, social and cultural changes in society, and exposure to modern digital technology undoubtedly have an impact on children's activity and lifestyle behavior. In fact, marked reductions in children's physical activity levels have been reported over the years and sedentary behavior has increased around the world. The question arises whether these environmental changes had an …
The relationship of parenting style and eating behavior in preschool children

Sleep and Health-Related Characteristics among Adolescents during Covid-19
Two opposing effects on adolescents' health during COVID-19 lockdown have been described: A beneficial one due to longer sleep times during school closures and a detrimental one of psychological distress. This study investigated how sleep and health changed in the course of the pandemic when schools were open again. Overall, 12,238 adolescents in Switzerland participated in three cross-sectional online surveys: In 2017 under regular conditions (c…
Development of the circadian system in early life
In humans, an adaptable internal biological system generates circadian rhythms that maintain synchronicity of behavior and physiology with the changing demands of the 24-h environment. Development of the circadian system begins in utero and continues throughout the first few years of life. Maturation of the clock can be measured through sleep/wake patterns and hormone secretion. Circadian rhythms, by definition, can persist in the absence of envi…

Motor Competence and Physical Activity in Early Childhood
Background Normal motor development and adequate levels of engagement in physical activity during the early years of life form the foundation of long-term psychological and physiological health. This is one of the very few studies that investigate the stability and relationships of motor competence and physical activity in preschool children. Methods Baseline and 12-month follow-up data of 550 preschool children aged 2 to 6 years from the Swiss P…
Using Participatory Methods to Develop and Implement Research on Historical Compulsory Social Measures and Placements in Switzerland
Many of the child welfare policies and practices in Switzerland before the law reform of 1981 were rather invasive and were exercised under a legal context that sometimes threatened basic human rights. The inclusion of survivors of such measures in the research process has been vigorously requested in Switzerland. Therefore, four individuals who had been placed in institutions as children have been included in the process of preparing a recently …
A Novel Approach to Assess Sleep-Related Rhythmic Movement Disorder in Children Using Automatic 3D Analysis
Background: Unlike other episodic sleep disorders in childhood, there are no agreed severity indices for rhythmic movement disorder. While movements can be characterized in detail by polysomnography, in our experience most children inhibit rhythmic movement during polysomnography. Actigraphy and home video allow assessment in the child's own environment, but both have limitations. Standard actigraphy analysis algorithms fail to differentiate rhyt…
Accelerometer-derived physical activity estimation in preschoolers – comparison of cut-point sets incorporating the vector magnitude vs the vertical axis

Prevalence and Predictors of Behavioral Problems in Healthy Swiss Preschool Children Over a One Year Period
Emotional eating is related with temperament but not with stress biomarkers in preschool children
Emotional eating (EE) corresponds to a change in eating behavior in response to distress and results in an increase of food intake (overeating (EOE)) or in food avoidance (undereating (EUE)). EE has been related to temperament (i.e. negative emotionality) and dysregulated stress biomarkers in school-aged children; parenting has been understood to influence this relationship in older children. The aim of the study was to investigate to which exten…

All articles of this category Einleitung Kinder gleichen Alters sind sehr verschieden. Auch das einzelne Kind ist in sich unterschiedlich weit entwickelt. So kann zum Beispiel das eine Kind in der Motorik weiter fortgeschritten sein als in seiner intellektuellen Entwicklung, während ein anderes Kind sprachlich sehr begabt, aber motorisch ungeschickt ist. Seine Entwicklung verläuft also nicht im Gleichschritt. Jedes Kind verfügt über ein individue…
Standardization of the Tanner-Whitehouse bone age method in the context of automated image analysis
The new automated TW ratings show good accuracy relative to the manual ratings of the Zurich data and the Gold Series. There are significant differences between manual TW raters, an effect which is eliminated with the automated method
Association between sleep duration and intelligence scores in healthy children
We examined the association between sleep behavior and cognitive functioning in 60 healthy children between 7 and 11 years of age under nonexperimental conditions. Intellectual abilities were assessed by the Wechsler Intelligence Scale for Children (4th edition) and sleep variables by questionnaires, actigraphy, and sleep diaries. Correlation analysis revealed a negative association between sleep duration on weekends and measures of intelligence …
Sleep Duration From Infancy to Adolescence
Objective. The main purpose of the present study was to calculate percentile curves for total sleep duration per 24 hours, for nighttime and for daytime sleep duration from early infancy to late adolescence to illustrate the developmental course and age-specific variability of these variables among subjects. Methods. A total of 493 subjects from the Zurich Longitudinal Studies were followed using structured sleep-related questionnaires at 1, 3, 6…
