(Journal article; Peer reviewed, 2016-12-12)Background: Sedentary behaviours (SB) are highly prevalent in young people and may be adversely associated with physical and mental health. Understanding of the modifiable determinants of SB is necessary to inform the ... -
Does birth weight influence physical activity in youth? a combined analysis of four studies using objectively measured physical activity
Ridgway, Charlotte L.; Brage, Søren; Sharp, Stephen J.; Corder, Kirsten; Westgate, Kate; van Sluijs, Esther M. F.; Goodyer, Ian M.; Hallal, Pedro C.; Anderssen, Sigmund A.; Sardinha, Luis B.; Andersen, Lars Bo; Ekelund, Ulf (Journal article; Peer reviewed, 2011-01-12)Animal models suggest growth restriction in utero leads to lower levels of motor activity. Furthermore, individuals with very low birth weight report lower levels of physical activity as adults. The aim of this study was ... -

Collings, Paul J.; Wijndaele, Katrien; Corder, Kirsten; Westgate, Kate; Ridgway, Charlotte L.; Dunn, Valerie; Goodyer, Ian; Ekelund, Ulf; Brage, Søren (Journal article; Peer reviewed, 2014-02-24)Background: Few studies have quantified levels of habitual physical activity across the entire intensity range. We aimed to describe variability in total and intensity-specific physical activity levels in UK adolescents ... -
Magnitude and determinants of change in objectively-measured physical activity, sedentary time and sleep duration from ages 15 to 17.5y in UK adolescents: the ROOTS study.
Collings, Paul J.; Wijndaele, Katrien; Corder, Kirsten; Westgate, Kate; Ridgway, Charlotte L.; Sharp, Stephen J.; Dunn, Valerie; Goodyer, Ian; Ekelund, Ulf; Brage, Søren (Journal article; Peer reviewed, 2015-05-14)Background: Self-reported physical activity (PA) and sleep duration (SLP) change markedly throughout adolescence. We sought to quantify changes in objectively-measured PA, sedentary time (ST) and SLP through adolescence, ... -
