      Hansen, Bjørge Herman; Anderssen, Sigmund Alfred; Andersen, Lars Bo; Hildebrand, Maria; Kolle, Elin; Steene-Johannessen, Jostein; Kriemler, Susi; Page, Angie S.; Puder, Jardena J.; Reilly, John J.; Sardinha, Luis B.; van Sluijs, Esther M.F.; Wedderkopp, Niels; Ekelund, Ulf (Peer reviewed; Journal article, 2018)
      Introduction Sedentary time and time spent in various intensity-specific physical activity are co-dependent, and increasing time spent in one behaviour requires decreased time in another. Objective The aim of the present ...
    • Harmonising data on the correlates of physical activity and sedentary behaviour in young people: Methods and lessons learnt from the international Children's Accelerometry database (ICAD) 

      Atkin, Andrew J.; Biddle, Stuart J. H.; Broyles, Stephanie T.; Chinapaw, Mai; Ekelund, Ulf; Esliger, Dale W.; Hansen, Bjørge Herman; Kriemler, Susi; Puder, Jardena J.; Sherar, Lauren B.; van Sluijs, Esther M.F.; Andersen, Lars Bo; Anderssen, Sigmund A.; Cardon, G.; Davey, R.; Hallal, P.; Janz, K. F.; Møller, N.; Molloy, L.; Page, A.; Pate, R.; Reilly, J.; Salmon, J.; Sardinha, L. B.; Timperio, A. (Peer reviewed; Journal article, 2017)
      Background: Large, heterogeneous datasets are required to enhance understanding of the multi-level influences on children’s physical activity and sedentary behaviour. One route to achieving this is through the pooling and ...
    • Perceived family functioning and friendship quality: cross-sectional associations with physical activity and sedentary behaviours 

      Atkin, Andrew J.; Corder, Kirsten; Goodyer, Ian M.; Bamber, Diane J; Ekelund, Ulf; Brage, Søren; Dunn, Valerie J.; van Sluijs, Esther M.F. (Journal article; Peer reviewed, 2015-02-21)
      Background: This study examined the association of adolescent-reported family functioning and friendship quality with objectively-measured moderate to vigorous physical activity (MVPA), sedentary time, and self-reported ...
    • Revising on the run or studying on the sofa: prospective associations between physical activity, sedentary behaviour, and exam results in British adolescents. 

      Corder, Kirsten; Atkin, Andrew J.; Bamber, Diane J.; Brage, Søren; Dunn, Valerie J.; Ekelund, Ulf; Owens, Matthew; van Sluijs, Esther M.F.; Goodyer, Ian M. (Journal article; Peer reviewed, 2015-09-04)
      Background: We investigated prospective associations between physical activity/sedentary behaviour (PA/SED) and General Certificate of Secondary Education (GCSE) results in British adolescents. Methods: Exposures were ...
    • Substituting prolonged sedentary time and cardiovascular risk in children and youth: a meta-analysis within the International Children’s Accelerometry database (ICAD) 

      Wijndaele, Katrien; White, Thomas; Andersen, Lars Bo; Bugge, Anna; Kolle, Elin; Northstone, Kate; Wedderkopp, Niels; Ried-Larsen, Mathias; Kriemler, Susi; Page, Angie S.; Puder, Jardena J.; Reilly, John J.; Sardinha, Luis B.; van Sluijs, Esther M.F.; Sharp, Stephen J.; Brage, Søren; Ekelund, Ulf (Peer reviewed; Journal article, 2019)
      Background: Evidence on the association between sitting for extended periods (i.e. prolonged sedentary time (PST)) and cardio-metabolic health is inconsistent in children. We aimed to estimate the differences in cardiometabolic ...
    • Variations in accelerometry measured physical activity and sedentary time across Europe: Harmonized analyses of 47,497 children and adolescents

    • Weather and children's physical activity; How and why do relationships vary between countries? 

      Harrison, Flo; Goodman, Anna; van Sluijs, Esther M.F.; Andersen, Lars Bo; Cardon, Greet; Davey, Rachel; Janz, Kathleen F.; Kriemler, Susi; Molloy, Lynn; Page, Angie S.; Pate, Russ; Puder, Jardena J.; Sardinha, Luís B.; Timperio, Anna; Wedderkopp, Niels; Jones, Andy P. (Peer reviewed; Journal article, 2017)
      Background: Globally most children do not engage in enough physical activity. Day length and weather conditions have been identified as determinants of physical activity, although how they may be overcome as barriers is ...
