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 ...
After-school hours are considered critical for children's physical activity (PA) and sedentary behaviors (SB); however, whether the after-school setting influences children's activity patterns is unknown. This study examined the influence of after-school setting (i.e., parent report of the child's usual after-school setting) on 5th grade children's PA and SB, ...
Objective This study aimed to determine the difference in body composition and its effect on 24 hour fat oxidation and dietary fat oxidation between Asians and Caucasians. Methods Seventeen Asians, (8 males) were matched for BMI, age and gender with 17 Caucasians. Physical activity was measured for 7 days with an accelerometer, followed by ...
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 ...
Introduction There is much interest in children’s physical activity (PA), but little understanding of its control. The evidence that total activity levels could be increased by the provision of greater opportunity for physical activity is lacking. Methods and Participants MTI-Actigraph accelerometers recorded weekly PA in two groups of healthy ...
Purpose Sedentary behaviour is known to have a detrimental effect on health. However, the manner in which is it accumulated may also be important. Therefore, we examined the association of daily sedentary time and breaks in sedentary time with various markers of cardio-metabolic risk. Methods Cross-sectional analysis using 725 participants from ...
