Low Physical Activity Level and Short Sleep Duration Are Associated with an Increased Cardio-Metabolic Risk Profile: A Longitudinal Study in 8-11 Year Old Danish Children

  • Published on Aug. 7, 2014

Background: As cardio-metabolic risk tracks from childhood to adulthood, a better understanding of the relationship between movement behaviors (physical activity, sedentary behavior and sleep) and cardio-metabolic risk in childhood may aid in preventing metabolic syndrome (MetS) in adulthood. Objective: To examine independent and combined cross-sectional and longitudinal associations between movement ...



Physical Activity and Skills Intervention: SCORES Cluster Randomized Controlled Trial

  • Published on July 18, 2014

Purpose: Physical activity declines dramatically during adolescence and activity levels are consistently lower among children living in low-income communities. Competency in a range of fundamental movement skills (FMS) may serve as a protective factor against the decline in physical activity typically observed during adolescence. The purpose of this study was ...


Identifying Children's Nocturnal Sleep Using 24-h Waist Accelerometry

  • Published on Sept. 8, 2014

Purpose: The purposes of this study were (1) to add layers and features to a previously published fully automated algorithm designed to identify children's nocturnal sleep and to exclude episodes of nighttime non-wear/wakefulness and potentially misclassified day time sleep episodes, and (2) to validate this refined sleep algorithm (RSA) against sleep ...


The associations of objectively measured physical activity and sedentary time with cognitive functions in school-aged children

  • Published on July 25, 2014

Abstract: Low levels of physical activity among children have raised concerns over the effects of a physically inactive lifestyle, not only on physical health but also on cognitive prerequisites of learning. This study examined how objectively measured and self-reported physical activity and sedentary behavior are associated with cognitive functions in ...


Prediction of activity type in preschool children using machine learning techniques

  • Published on June 24, 2014

Objectives: Recent research has shown that machine learning techniques can accurately predict activity classes from accelerometer data in adolescents and adults. The purpose of this study is to develop and test machine learning models for predicting activity type in preschool-aged children. Design: Participants completed 12 standardised activity trials (TV, reading, tablet ...


A repeated measurement study investigating the impact of school outdoor environment upon physical activity across ages and seasons in Swedish second, fifth and eighth graders

  • Published on Aug. 7, 2014

Background: School children are confined to and exposed to outdoor environment that happens to be at their disposal during compulsory school time. The health-promoting potential of outdoor environment, and the use of it, is therefore important. We have studied the impact of school outdoor environment in terms of playground features, ...


Associations between objectively assessed child and parental physical activity: a cross-sectional study of families with 5–6 year old children

  • Published on June 27, 2014

Background: A number of studies have suggested that there is a need to increase the physical activity levels of children. Parents are important influences on children’s behaviour. There is a lack of information about whether there are associations between the physical activity levels of young children and their parents. ...


Differences in Physical Activity among Youth with and without Intellectual Disability.

  • Published on June 30, 2014

Introduction: Very little is known about physical activity (PA) and PA patterns measured with objective methods among children with intellectual disability (ID). Purpose: To investigate PA and PA patterns among Icelandic school children with mild-to-severe ID. Methods: A sample of 91 children with ID and a randomly selected age- and sex-matched ...


Validity of the Omron pedometer and the actigraph step count function in preschoolers

  • Published on June 12, 2014

Objectives: To validate the GT1M actigraph accelerometer step count function, and the Omron Walking Style Pro pedometer against accelerometer-based activity counts, and to compare pedometer-based and accelerometer-based steps in preschoolers. Design: A sample of 41 preschoolers (21 boys, mean age 5.43 ± 0.63 years) from one preschool in Flanders, Belgium, was included in data ...
