Comparison of a physical activity recall questionnaire with accelerometry in children and adolescents with obesity: a pilot study

  • Published on Sep 21, 2016

This study aimed to determine the validity of the Habitual Activity Estimation Scale (HAES) for assessing physical activity (PA) in children and adolescents with severe obesity. Data were obtained from participants (n = 17) in the High Impact Strategies Toward Overweight Reduction in Youth study at the Hospital for Sick Children ...


Effect of Accelerometer Cut-Off Points on the Recommended Level of Physical Activity for Obesity Prevention in Children

  • Published on Oct 10, 2016

There is no general consensus regarding which accelerometer cut-off point (CoP) is most acceptable to estimate the time spent in moderate-to-vigorous physical activity (MVPA) in children and choice of an appropriate CoP primarily remains a subjective decision. Therefore, this study aimed to analyze the influence of CoP selection on the ...


Physical Activity and Sedentary Time among Children with Disabilities at School

  • Published on Feb 2017

Purposes: Physical activity (PA) is important for the development of children with disabilities, but rarely does this population meet the recommended standards. Schools are salient locations for PA, but little is known about how specific school settings affect the PA of children with diverse disabilities. We assessed PA and sedentary ...


Physical Activity in Pediatric Pulmonary Arterial Hypertension Measured by Accelerometry: A Candidate Clinical Endpoint

  • Published on July 15, 2017

Background Although the six-minute walk distance is well established as a clinically relevant endpoint for adults with pulmonary arterial hypertension (PAH), this endpoint is less applicable to infants and children who may be unable to participate in such testing. Thus, there is a critical need to develop and validate means ...


A randomised controlled trial of multiple periods of outdoor free-play to increase moderate-to-vigorous physical activity among 3 to 6 year old children attending childcare: study protocol

  • Published on Sep 2, 2016

Background: The implementation of physical activity interventions in centre-based childcare services has been recommended to improve child health. This study aims to evaluate the efficacy of scheduling multiple periods of outdoor free play in increasing the time children spend in moderate-to-vigorous physical activity (MVPA) during childcare. Methods: The study will ...


Effects of physical activity on schoolchildren’s academic performance: The Active Smarter Kids (ASK) cluster-randomized controlled trial

  • Published on Sep 7, 2016

Objective: To investigate the effect of a seven-month, school-based cluster-randomized controlled trial on academic performance in 10-year-old children. Methods: In total, 1129 fifth-grade children from 57 elementary schools in Sogn og Fjordane County, Norway, were cluster-randomized by school either to the intervention group or to the control group. The children in the 28 ...


Longitudinal associations of lifestyle factors and weight status with insulin resistance (HOMA-IR) in preadolescent children: the large prospective cohort study IDEFICS

  • Published on Sep 2, 2016

Background: This study investigates prospective associations of anthropometrical and lifestyle indices with insulin resistance (IR) in European children from the IDEFICS cohort. Insulin resistance (IR) is a growing concern in childhood obesity and a central aspect of the metabolic syndrome (MS). It most likely represents the link between obesity and ...


Longitudinal Growth, Diet, and Physical Activity in Young Children With Cerebral Palsy

  • Published on Sep 7, 2016

Objectives: To describe the longitudinal relationship between height-for-age z score (HZ), growth velocity z score, energy intake, habitual physical activity (HPA), and sedentary time across Gross Motor Function Classification System (GMFCS) levels I to V in preschoolers with cerebral palsy (CP). Methods: Children with CP (n = 175 [109 (62.2%) boys]; mean recruitment age 2 ...


Household-level correlates of children’s physical activity levels in and across 12 countries

  • Published on Aug 25, 2016

Objective: Household factors (electronic media equipment, play equipment, physical activity in the home, and social support) have been associated with childhood moderate- to vigorous-intensity physical activity (MVPA), but little is known about how these factors differ across diverse countries. The objective was to explore household correlates of objective MVPA in ...


Neighborhoods for Active Kids: study protocol for a cross-sectional examination of neighborhood features and children’s physical activity, active travel, independent mobility and body size

  • Published on Aug 1, 2016

Introduction: New Zealand children's physical activity, including independent mobility and active travel, has declined markedly over recent decades. The Neighbourhoods for Active Kids (NfAK) study examines how neighbourhood built environments are associated with the independent mobility, active travel, physical activity and neighbourhood experiences of children aged 9–12 years in ...
