Empirically derived cut-points for sedentary behaviour: are we sitting differently?

  • Published on Sep 21, 2016

Sedentary behaviour (SB) is associated with a number of adverse health outcomes. Studies that have used ActiGraph monitors to define sedentary time tend to use a threshold of  <100 counts per minute (cpm) for classifying SB; however, this cut-point was not empirically derived for adults. It is not known ...


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 ...


Estimating Physical Activity and Sedentary Behavior in a Free-Living Context: A Pragmatic Comparison of Consumer-Based Activity Trackers and ActiGraph Accelerometry

  • Published on Jul 9, 2016

Background: Activity trackers are increasingly popular with both consumers and researchers for monitoring activity and for promoting positive behavior change. However, there is a lack of research investigating the performance of these devices in free-living contexts, for which findings are likely to vary from studies conducted in well-controlled laboratory settings. ...


Does duration of physical activity bouts matter for adiposity and metabolic syndrome? A cross-sectional study of older British men

  • Published on Mar 15. 2016

Background: Older adults have low physical activity(PA) and high sedentary behaviour(SB) levels. We investigate how total volume and specific patterns of moderate to vigorous PA(MVPA), light PA(LPA) and SB are related to adiposity and metabolic syndrome (MS). Then, with reference to physical activity guidelines which encourage ...


School grounds and physical activity: Associations at secondary schools, and over the transition from primary to secondary schools

  • Published on May 2016

This paper aims to further understanding of the physical environments of secondary schools and their associations with young peoples' physical activity. Accelerometer-derived physical activity measurements from 299 participants in the SPEEDY study (Norfolk, UK) were obtained from baseline measurements (age 9–10 y) and +4y follow-up. These were linked to objective measures ...


Investigating elementary school children’s daily physical activity and sedentary behaviours during weekdays

  • Published on Mar 7, 2016

The purpose of the study was to quantify the contributions of physical education, exergaming (active video games that also are a type of exercise), recess, lunch break and after-school time segments to children’s daily physical activity and sedentary behaviours. Participants were 138 second and third graders (71 girls) who attended 20-min ...


Validation of thigh-based accelerometer estimates of postural allocation in 5–12 year-olds

  • Published on Aug 12, 2016

Objectives: To validate activPAL3™ (AP3) for classifying postural allocation, estimating time spent in postures and examining the number of breaks in sedentary behaviour (SB) in 5–12 year-olds. Design: Laboratory-based validation study. Methods: Fifty-seven children completed 15 sedentary, light- and moderate-to-vigorous intensity activities. Direct observation (DO) was used as the criterion ...


Assessment of sedentary behaviors and transport-related activities by questionnaire: a validation study

  • Published on Aug 9, 2016

Background: Comprehensive assessment of sedentary behavior (SB) and physical activity (PA), including transport-related activities (TRA), is required to design innovative PA promotion strategies. There are few validated instruments that simultaneously assess the different components of human movement according to their context of practice (e.g. work, transport, leisure). We examined ...


Does home equipment contribute to socioeconomic gradients in Australian children’s physical activity, sedentary time and screen time?

  • Published on Aug 5, 2016

Background: Activity behaviours (physical activity, sedentary time and screen time) have been linked to health outcomes in childhood. Furthermore, socioeconomic disparities have been observed in both children’s activity behaviours and health outcomes. Children’s physical home environments may play a role in these relationships. This study aimed to examine ...
