Associations between gross motor skills and physical activity in Australian toddlers

  • Published on December 20, 2017

OBJECTIVES Physical activity can be promoted by high levels of gross motor skills. A systematic review found a positive relationship in children (3-18 years) but only few studies examined this in younger children. The aim of this study was to examine the association between gross motor skills and physical activity ...


Using accelerometers to characterize recovery after surgery in children.

  • Published on Oct 6, 2017

Background: Assessment of recovery after surgery in children remains highly subjective. However, advances in wearable technology present an opportunity for clinicians to have an objective assessment of postoperative recovery. The aims of this pilot study are to: (1) evaluate acceptability of accelerometer use in pediatric surgical patients, (2) use accelerometer data to ...


Does sleep disruption mediate the effects of childhood maltreatment on brain structure?

  • Published on May 31, 2018

Background: Childhood maltreatment is associated with alterations in morphology of stress susceptible brain regions. Maltreatment is also known to markedly increase risk for psychopathology and to have an enduring disruptive effect on sleep. Objective: To determine whether abnormalities in sleep continuity have effects on brain morphometry and to evaluate the ...


Comparability of children’s sedentary time estimates derived from wrist worn GENEActiv and hip worn ActiGraph accelerometer thresholds

  • Published on Apr 2018

Objectives: To examine the comparability of children’s free-living sedentary time (ST) derived from raw acceleration thresholds for wrist mounted GENEActiv accelerometer data, with ST estimated using the waist mounted ActiGraph 100 count · min−1 threshold. Design: Secondary data analysis. Methods: 108 10–11-year-old children (n = 43 boys) from Liverpool, UK wore one ActiGraph GT3...



Physical activity quantified by questionnaire and accelerometry in schoolchildren. A comparison

  • Published on Feb 9, 2018

Introduction: Questionnaires have long been the tool of choice for the measurement of physical activity in large population groups, however, they depend on the accuracy with which they are answered. Accelerometers, on the other hand, can directly measure physical activity, eliminate subjectivity and, allow comparisons with instruments such as questionnaires. ...


Physical activity and sedentary behavior following pediatric burns – a preliminary investigation using objective activity monitoring

  • Published on Feb 9, 2018

Background: Adequate levels of regular physical activity (PA) are crucial for health and well-being. Pediatric burn injuries can have major physiological consequences in both the short and long term. The question is whether these consequences affect post burn PA levels. This study therefore aimed to describe PA and sedentary behavior (...


Children’s physical activity levels during organised sports practices

  • Published on Feb 8, 2018

Objectives: This study measured the physical activity levels of children during practice sessions of four popular organised sports in Australia. Design: Cross-sectional observational design. Methods: Participants comprised children from four local organised sports clubs in suburban Adelaide, South Australia. The sports examined were Australian Rules Football (AFL), girls’ netball, boys’ ...


Parental body mass index and its association with body composition, physical fitness and lifestyle factors in their 4-year-old children: results from the MINISTOP trial

  • Published on Oct 2017

Background/Objectives: To examine the association between parental body mass index (BMI) and their offspring's body composition, physical fitness and lifestyle factors (that is, sedentary time, physical activity and diet). Subjects/Methods: A total of 307 preschoolers (4.5±0.1 years) and their parents (fathers: 38.1±5.1 years and mothers: 35.6±4.2 years) participated in this study. Parental ...
