Changes in time-segment specific physical activity between ages 10 and 14 years: A longitudinal observational study

  • Published on Jan. 2016

Objectives: Describe (1) time-segment specific changes in physical activity (PA) into adolescence, (2) differences in change in PA between specific time-segments (weekdays–weekends, in-school–out-of-school, out-of-school–weekends, lesson-time–lunch-time), and (3) associations of change in time-segment specific with overall PA. Design: Longitudinal observational study (4-year follow-up). Methods: Children from the SPEEDY study (n = 769, 42% ...


The effect of a cluster randomised control trial on objectively measured sedentary time and parental reports of time spent in sedentary activities in Belgian preschoolers: the ToyBox-study

  • Published on Jan. 5, 2016

Background: In preschoolers, high levels of sedentary behaviour are associated with several adverse health outcomes. The purpose of this study is to report the effects of the ToyBox-intervention (a European 24-week cluster randomised controlled trial) on sedentary behaviour in preschoolers. Methods: In Belgium, 859 preschoolers from 27 kindergartens (15 intervention and 12 control) wore ...


Nocturnal sleep-related variables from 24-h free-living waist-worn accelerometry: International Study of Childhood Obesity, Lifestyle and the Environment

  • Published on Dec. 2015

Objectives: We describe the process of identifying and defining nocturnal sleep-related variables (for example, movement/non-movement indicators of sleep efficiency, waking episodes, midpoint and so on) using the unique 24-h waist-worn free-living accelerometer data collected in the International Study of Childhood Obesity, Lifestyle and the Environment (ISCOLE). Methods: Seven consecutive ...


Cross-sectional and prospective associations between moderate to vigorous physical activity and sedentary time with adiposity in children

  • Published on Oct. 13, 2015

Background: Physical activity (PA) and sedentary time (SED) have both been suggested as potential risk factors for adiposity in children. However, there is paucity of data examining the temporal associations between these variables. Objective: This study aimed to analyze the cross-sectional and prospective associations between PA, SED and body composition ...





The objective measurement of physical activity and sedentary behaviour in 2–3 year olds and their parents: a cross-sectional feasibility study in the bi-ethnic Born in Bradford cohort

  • Published on Nov. 11, 2015

Background: The reported lower physical activity (PA) levels of British South Asians (SA) are suggested as a key influence in their increased risk of non-communicable diseases compared to their White British peers. Differences in objectively measured PA and sedentary behaviour (SB) between these ethnic groups have been observed during childhood (...


Agreement of objectively measured physical activity and sedentary time in preschool children

  • Published on July 21, 2015

Objective: To determine the intra-individual agreement for objectively measured physical activity (PA) and sedentary behavior (SED) over two subsequent weeks in preschool children. Method: Ninety-one children aged 3 to 5 years (49% boys) from three preschools in Sogn og Fjordane, Norway, provided 14 consecutive days of accelerometer data (Actigraph GT3X +) during the autumn ...


Too hot to move? Objectively assessed seasonal changes in Australian children’s physical activity

  • Published on June 19, 2015

Background: Seasonal variations may influence children’s physical activity patterns. The aim of this study was to examine how children’s objectively-measured physical activity differed across seasons, and whether different seasonal patterns were observed for boys and girls. Methods: Three hundred and twenty-six children aged 8–11 years from nine primary schools ...
