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 ...


Physical Activity Levels and Nutritional Knowledge's Among Children and Adolescents

  • Presented on July 3, 2014

Introduction: Childhood obesity is a consequence of environments that disrupt the balance of energy intake and energy expenditure. Obesogenic environments consist of social norms and environmental factors that facilitate unhealthy behaviors around diet and physical activity. Nutritional knowledge and physical activity are cornerstones of every obesity treatment. The aims are ...



Project PANK: Rationale, Design and Baseline Results of a Multidisciplinary School-Based Intervention in Children with Cardiovascular and Metabolic Risk Factors. A Randomized Controlled Trial.

  • Presented on July 3, 2014

Introduction: Atherosclerosis begins in youth and is related to the presence of cardiovascular and metabolic risk factors (CMRF): age, gender, nutrition, physical inactivity, cardiorespiratory fitness (CF), blood pressure (BP), lipids and overweight/obesity. There is strong evidence showing that schools should include nutrition and physical activity (PA) in the curriculum. ...
