• Accelerometer epoch setting is decisive for associations between physical activity and metabolic health in children 

      Aadland, Eivind; Andersen, Lars Bo; Anderssen, Sigmund Alfred; Resaland, Geir Kåre; Kvalheim, Olav Martin (Journal article; Peer reviewed, 2019)
      When analysing physical activity (PA) levels using accelerometry, the epoch setting is critical to capture intensity-specific PA correctly. The aim of the present study was to investigate the PA intensity signatures related ...
    • Dynamic sitting: Measurement and associations with metabolic health 

      van der Berg, Julianne D.; Stehouwer, Coen D.A.; Bosma, Hans; Caserotti, Paolo; Eiríksdóttir, Gudny; Arnardóttir, Nanna Y.; van Domelen, Dane R.; Brychta, Robert J.; Chen, Kong Y.; Sveinsson, Thorarinn; Johannsson, Erlingur; Launer, Lenore J.; Gudnason, Vilmundur; Jonsson, Palmi V.; Harris, Tamara B.; Koster, Annemarie (Peer reviewed; Journal article, 2019)
      Dynamic sitting, such as fidgeting and desk work, might be associated with health, but remains difficult to identify out of accelerometry data. We examined, in a laboratory study, whether dynamic sitting can be identified ...
    • Effects of the Active Smarter Kids (ASK) physical activity intervention on cardiometabolic risk factors in children: A cluster-randomized controlled trial 

      Stavnsbo, Mette; Aadland, Eivind; Anderssen, Sigmund Alfred; Chinapaw, Mai; Steene-Johannessen, Jostein; Andersen, Lars Bo; Resaland, Geir Kåre (Peer reviewed; Journal article, 2019)
      The onset of cardiometabolic diseases are recognized to occur in childhood. We aimed to investigate the effect of a school-based cluster-randomized controlled trial of physical activity (PA) on single and clustered ...
    • Long-term correlates of objectively measured physical activity and sedentary time in norwegian men and women 

      Solbraa, Ane; Ekelund, Ulf; Holme, Ingar Morten K.; Graff-Iversen, Sidsel; Steene-Johannessen, Jostein; Aadland, Eivind; Anderssen, Sigmund A. (Journal article; Peer reviewed, 2015)
      Background: Sex, age, body mass index (BMI), perceived health and health behavior are correlates known to affect physical activity and sedentary time. However, studies have often been cross-sectional, and less is known ...
    • Reproducibility of domain-specific physical activity over two seasons in children 

      Aadland, Eivind; Andersen, Lars Bo; Ekelund, Ulf; Anderssen, Sigmund Alfred; Resaland, Geir Kåre (Journal article; Peer reviewed, 2018)
      Background Knowledge of the reproducibility of domain-specific accelerometer-determined physical activity (PA) estimates are a prerequisite to conduct high-quality epidemiological studies. The aim of this study was to ...
    • Reproducibility of objectively measured physical activity: Reconsideration needed 

      Aadland, Eivind; Nilsen, Ada Kristine Ofrim; Ylvisåker, Einar; Johannessen, Kjersti; Anderssen, Sigmund Alfred (Peer reviewed; Journal article, 2020)
      Reliability of accelerometer-determined physical activity (PA), and thus the required length of a monitoring period, appears to depend on the analytic approach used for its calculation. We compared reliability of objectively ...
