Objectives Decreased physical activity levels in children may partly explain the rising prevalence of functional constipation in childhood. The aim of the present study, therefore, was to examine the association between physical activity and functional constipation during the preschool period. Methods This study was embedded in the Generation R study, ...
Background To assess the relationship between physical activity in second year of life and respiratory symptoms during the pre-school period. Methods This study was embedded in the Generation R Study, a large prospective birth-cohort study in Rotterdam, the Netherlands. Physical activity was measured in the second year of life by ...
Objective To calibrate and validate the ActiGraph GT3X+ to measure sedentary behaviour (SB) and physical activity (PA) in 2-3 year olds, using 5-second epochs; and to compare the predictive validity of the resulting cut-points with that of NHANES’, Trost's, and Pate's 15-second cut-points. Design Cross-sectional study Method Eighteen children (2.86 ± 0.60...
Background Adequate sleep is a critical factor for adolescent’s health and health-related behaviors Objective (a) to describe sleep duration in European adolescents from nine countries, (b) to assess the association of short sleep duration with excess adiposity and (c) to elucidate if physical activity (PA), sedentary behaviors and/or ...
Purpose Accurate, nonintrusive and feasible methods are needed to predict energy expenditure (EE) and physical activity (PA) levels in preschoolers. Herein, we validated cross-sectional time series (CSTS) and multivariate adaptive regression splines (MARS) models based on accelerometry and heart rate (HR) for prediction of EE using room calorimetry and doubly ...
Background Understanding fluctuations in lifestyle indicators is important to identify relevant time periods to intervene in order to promote a healthy lifestyle; however, objective assessment of multiple lifestyle indicators has never been done using a repeated-measures design. The primary aim was, therefore, to examine between-season and within-week variation in physical ...
Abstract This study examines the association between objectively-measured physical activity (PA) intensities and sedentary behaviour (SED) in a cohort of 532 children aged 8-10 y. PA and SED were assessed by accelerometer over 7-days. Television and computer/video-game use were self-reported. Associations between PA intensities and SED variables were assessed by ...
Objective To determine the independent associations of moderate to vigorous physical activity (MVPA), fitness, screen time, and adiposity with insulin secretion in children. Design and Methods Caucasian youth (n = 423/630), 8-10 years old, with at least one obese biological parent, were studied (QUALITY cohort). Insulin secretion was measured using HOMA2-%...
Abstract The objective of this study was to examine the combined associations between time spent in moderate- to vigorous-intensity physical activity (MVPA) and time spent sedentary in relation to cardiometabolic risk factors in a cohort of Canadian children. A cross-sectional study was conducted on 536 white children aged 8–10 years with at ...
Objective To investigate the independent associations between objectively measured levels of movement intensity (i.e. time spent sedentary and at light, moderate and vigorous intensities) and indicators of adiposity in a cohort of Canadian children. Methods A cross-sectional study was conducted in 550 Caucasian children aged 8–10 years with at least one ...
