• Age-related patterns of vigorous-intensity physical activity in youth: The International Children's Accelerometry Database 

      Corder, Kirsten; Sharp, Stepher J.; Atkin, Andrew J.; Andersen, Lars Bo; Cardon, Greet; Page, Angie; Davey, Rachel; Grøntvedt, Anders; Hallal, Pedro C.; Janz, Kathleen F.; Kordas, Katarzyna; Kriemler, Susi; Puder, Jardena J.; Sardinha, Luis B.; Ekelund, Ulf; van Sluijs, Esther M. F. (Journal article; Peer reviewed, 2016-05-16)
      Physical activity declines during youth but most evidence reports on combined moderate and vigorous-intensity physical activity. We investigated how vigorous-intensity activity varies with age. Cross-sectional data from ...
    • Association between maternal education and objectively measured physical activity and sedentary time in adolescents 

      Sherar, Lauren B.; Griffin, Tom P.; Ekelund, Ulf; Cooper, Ashley R.; Esliger, Dale W.; van Sluijs, Esther M. F.; Andersen, Lars Bo; Cardon, Greet; Davey, Rachel; Froberg, Karsten; Hallal, Pedro C.; Janz, Kathleen F.; Kordas, Katarzyna; Kriemler, Susi; Pate, Russell R.; Puder, Jardena J.; Sardinha, Luis B.; Timperio, Anna F.; Page, Angie S. (Journal article; Peer reviewed, 2016-01-22)
      Background: Investigating socioeconomic variation in physical activity (PA) and sedentary time is important as it may represent a pathway by which socioeconomic position (SEP) leads to ill health. Findings on the association ...
    • A closer look at the relationship among accelerometer-based physical activity metrics: ICAD pooled data 

      Kwon, Soyang; Andersen, Lars Bo; Grøntved, Anders; Kolle, Elin; Cardon, Greet; Davey, Rachel; Kriemler, Susi; Northstone, Kate; Page, Angie S.; Puder, Jardena J.; Reilly, John J.; Sardinha, Luís B.; van Sluijs, Esther M.F.; Janz, Kathleen F. (Peer reviewed; Journal article, 2019)
      Background: Accelerometers are widely used to assess child physical activity (PA) levels. Using the accelerometer data, several PA metrics can be estimated. Knowledge about the relationships between these different metrics ...
    • Objectively measured physical activity and sedentary time in youth: the International children’s accelerometry database (ICAD). 

      Cooper, Ashley R.; Goodman, Anna; Page, Angie S.; Sherar, Lauren B.; Esliger, Dale W.; van Sluijs, Esther M.F; Andersen, Lars Bo; Anderssen, Sigmund A.; Cardon, Greet; Davey, Rachel; Froberg, Karsten; Hallal, Pedro; Janz, Kathleen F.; Kordas, Katarzyna; Kreimler, Susi; Pate, Russell; Puder, Jardena; Reilly, John J.; Salmon, Jo; Sardinha, Luis B.; Timperio, Anna M.; Ekelund, Ulf (Journal article; Peer reviewed, 2015-09-17)
      Background: Physical activity and sedentary behaviour in youth have been reported to vary by sex, age, weight status and country. However, supporting data are often self-reported and/or do not encompass a wide range ...
    • Tracking of accelerometry-measured physical activity during childhood: ICAD pooled analysis 

      Kwon, Soyang; Janz, Kathleen F.; Cooper, Ashley R.; Ekelund, Ulf; Esliger, Dale W.; Griew, Pippa; Judge, Ken; Ness, Andy; Riddoch, Chris J.; Salmon, Jo; Sherar, Lauren (Journal article; Peer reviewed, 2012-06-07)
      Background Understanding of physical activity (PA) tracking during childhood is important to predict PA behaviors and design appropriate interventions. We compared tracking of PA according to PA level and type of day ...
    • 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 ...
