Do differences in compositional time use explain ethnic variation in the prevalence of obesity in children? Analyses using 24-hour accelerometry

  • Published on May 14, 2019

Background/Objectives: Whether variation in sleep and physical activity explain marked ethnic and socioeconomic disparities in childhood obesity is unclear. As time spent in one behaviour influences time spent in other behaviours across the 24-hour day, compositional analyses are essential. The aims of this study were to determine how ethnicity ...



Specific Sports Habits, Leisure‐Time Physical Activity, and School‐Educational Physical Activity in Children With Juvenile Idiopathic Arthritis: Patterns and Barriers

  • Published on Oct. 24, 2018

Objective: Juvenile idiopathic arthritis (JIA) may cause functional impairment and reduced time engaged in physical activity. The aim of this study was to investigate the habits of patients with JIA regarding participation in club sports, leisure‐time physical activity, and school‐educational physical activity and relate this to objectively measured ...


Effects of Interrupting Sedentary Behavior With Short Bouts of Moderate Physical Activity on Glucose Tolerance in Children With Overweight and Obesity: A Randomized Crossover Trial

  • Published on October 2018

Objective: Sedentary children have greater risk of developing abnormalities in glucose homeostasis. We investigated whether interrupting sedentary behavior (sitting) with very short periods of walking would improve glucose metabolism without affecting dietary intake in children with overweight or obesity. We hypothesized that interrupting sitting with short bouts of moderate-intensity walking ...



Physical activity and sedentary behavior across three time-points and associations with social skills in early childhood

  • Published on Jan 7, 2019

Background: The growth and development that occurs in early childhood has long-term implications, therefore understanding the relevant determinants is needed to inform early prevention and intervention. The objectives of the study were to examine: 1) the longitudinal associations of physical activity and sedentary behavior with social skills and 2) how physical activity ...



Comparison of Polar Active Watch and Waist- and Wrist-Worn ActiGraph Accelerometers for Measuring Children’s Physical Activity Levels during Unstructured Afterschool Programs

  • Published on Sep 4, 2018

Background: The purpose of this study was to examine the convergent validity of the Polar Active Watch (PAW), a consumer-grade wrist-worn activity monitor, against waist- and wrist-worn research-grade monitors, the ActiGraph GT3X+/GT9X accelerometers, in children. Methods: Fifty-one children (18 boys; mean age = 10.30 ± 0.91 years) wore the three monitors (PAW, ...


Correlates of intensity-specific physical activity in children aged 9-11 years: a multilevel analysis of UK data from the International Study of Childhood Obesity, Lifestyle and the Environment

  • Published on Feb 2018

Objectives: Physical activity (PA) can provide numerous physical and psychological health gains, yet a low proportion of children in England are sufficiently active to accrue benefit. Analyzing the correlates of PA from a socioecological perspective may help to identify factors that promote versus discourage PA. The purpose of the present ...


Impact of a classroom standing desk intervention on daily objectively measured sedentary behavior and physical activity in youth

  • Published on Mar 2, 2018

Objectives: We investigated the impact of a standing desk intervention on daily objectively monitored sedentary behavior and physical activity in 6th grade school students. Design: Cluster non-randomised controlled trial. Method: Two classes (intervention students: n=22 [aged 11.8±0.4years]; control students: n=27 [11.6±0.5years]) from a public school in Lisbon were selected. The ...
