Purpose The increasing prevalence of overweight and obesity in children and adolescents has been associated with a decline in physical activity (PA). The majority of children display insufficient activity levels (Trojano et al, 2008). Various environmental and biological constraints have been shown to influence children’s PA but only limited information ...
Objectives To investigate the impact of the CHANGE! curriculum-based intervention across time on children’s weekday and weekend day physical activity (PA) levels and to report effect of covariates on the outcome measures. Methods Twelve primary schools were randomised to an Intervention (N = 6) or Control condition. Baseline, 20-week post-intervention and 10...
Introduction Children with Down Syndrome (DS) have been demonstrated as being less active1 and have showed lower levels of physical fitness2 than children without DS. To date, the information regarding physical activity (PA) and persons with DS is limited and inconclusive. Therefore, the aim of this study was to assess ...
Objective Parents who overestimate their child's physical activity (PA) level may not encourage their children to increase their PA. We assessed parental awareness of child PA, and investigated potential correlates of overestimation. Method Child PA (accelerometer) and parent-classified child PA ['active' ≥ 60 min/day vs. 'inactive' <60 min/day moderate and ...
Background The Developmental Origins of Health and Disease hypothesis suggests that intrauterine, infancy and early childhood variables play a key role at programming later health. However, little is known on the programming of behavioral variables, because most studies so far focused on chronic disease-related and human capital outcomes. The aim ...
Objectives The purpose of this study was to determine whether ActiGraph accelerometer activity counts and estimates of moderate-to-vigorous physical activity collected at a single larger epoch are comparable to those collected at smaller epochs reintegrated into a larger epoch. Design A cross-sectional study design. Methods Thirty-one preschoolers (3–5 years) concurrently wore ...
Objectives The GT1M ActiGraph has been replaced by the triaxial GT3X which includes an inclinometer to detect postures. The purpose of this study was to investigate comparability of the GT3X to the GT1M and to develop activity intensity cut-points for the vector magnitude of the GT3...
Objective To evaluate the classification accuracy of five ActiGraph moderate-to-vigorous physical activity (MVPA) cut-point definitions in pre-school children using energy expenditure measured by whole-room calorimetry as the criterion measure. Methods 20 children aged 4-6 years (5.1 ± 0.8years) completed a ~50 min whole-room calorimeter protocol involving age-appropriate moderate and vigorous physical activities (eg. rumling ...
Objective To investigate the single and combined associations of physical activity (PA), body mass index (BMI), and sleep duration with clustering of cardiovascular disease risk markers in healthy children. Methods We did a cross-sectional pilot-study of 74 Danish school children aged 8-11 years. Risk factors included in a continuous metabolic syndrome ...
Introduction physical activity (PA) is perceived to be a key determinant of childhood adiposity. This study objectively characterizes the daily PA of 7-year-olds and relates it to waking time, intensity, UK recommendations and body fat. Methods and Participants MTI-Actigraph accelerometers were worn by 129 (88) healthy boys (girls) for seven days. Calibration ...
