Although engagement in social interactions is one of the key diagnostic features of autism spectrum disorders (ASDs), few studies have examined if social engagement related to physical activity of children with ASD. Age is another variable of interest to researchers studying behaviors, but has not been explored in physical activity ...
Measurement of physical activity in young children must be objective, since self or parental reports are not valid The advent of accelerometry has provided a practical and accurate means of objectively assessing engagement in habitual physical activity and inactivity (sedentary behavior) suitable even in young children. However; there is a ...
Objective
To explore the association between measures of insulin resistance with objectively assessed physical activity.
Design
School-based, cross-sectional study.
Subjects
A randomly selected sample of 589 children (310 girls, 279 boys, mean (standard deviations, s.d.) age=9.7 (0.44) y, weight=33.6 (6.4) kg, height=1.39 (0.06) m) from Denmark.
Methods
Fasting blood samples were analysed for serum insulin ...
Low physical activity has an important role in the development of obesity in youth. To date, little evidence exists on the physical activity patterns of severely obese young people and no study has examined their habitual activity using objective measurements. The aims of this study were to 1) objectively determine physical ...
Objective
This study aimed to describe levels of physical activity in a representative sample of preschool children and to quantify tracking of activity over 1 year.
Research Methods and Procedures
Physical activity (mean accelerometry counts/minute) was assessed over 3 days using the Computer Science and Applications accelerometer in 3- to 4-year-old ...
Self-report measures remain the most popular tool for measuring the habitual physical activity of large samples of children The Multimedia Activity Recall for Children and Adolescents (MARCA) is a computer delivered questionnaire which requires children to recall the previous 24-h in 5 min segments The MARCA retains the key features of ...
We examined the ability of the Computer Science Applications (CSA) accelerometer to predict energy expenditure during treadmill walking and stair stepping in nine children and adolescents with cystic fibrosis (CF) (mean age 12.1 yr, SD + 2.8) and ten healthy controls (mean age 10.8 yr. SD + 2.2). The accelerometer was attached above the hip and ...
Objective
To highlight the discrepancies in accelerometry cut-off points of moderate-to-vigorous physical activity (MVPA) according to the definitions of Puyau et al. (MVPA(P)) and Trost et al. (MVPA(T)).
Research Methods and Procedures
Forty-five children from 8 to 11 years old were monitored with the ActiGraph (ActiGraph, LLC, Fort Walton Beach, ...
There is increasing public health concern that levels of physical activity in children are extremely low. This study aimed to describe objectively levels of physical activity and sedentary behaviour during the waking hours in a sample of 4-5 year old (median 5.4 years range 4.3, 6.0) rural Irish children (n=41) and to test ...
Purpose
To examine the levels of PA in children and adolescents in relation to published recommendations.
Methods
total of 439 nine-year-olds (202 boys and 237 girls) and 364 fifteen-year-olds (156 boys and 208 girls) agreed to participate. Amount of PA was measured during four consecutive days (two weekdays and two weekend days) with an activity monitor (...
