    • Accelerometer-measured physical activity in Norwegian adolescents. Results from The Fit Futures Study 

      Beldo, Sigurd (Doctoral thesis; Doktorgradsavhandling, 2021-12-16)
      This thesis examined the prevalence and patterns of accelerometer-measured physical activity in a cohort of urban-rural older adolescents in Northern Norway, participating in the Fit Futures Study. The thesis also assessed the validity of self-reported physical activity against accelerometer measurements, and explored the association between accelerometer-measured physical activity and subsequent ...

    • Association between objectively measured physical activity and longitudinal changes in body composition in adolescents: the Tromsø study fit futures cohort 

      Aars, Nils Abel; Beldo, Sigurd; Jacobsen, Bjarne K.; Horsch, Alexander; Morseth, Bente; Emaus, Nina; Furberg, Anne-Sofie; Grimsgaard, Sameline (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-07)
      <i>Objectives</i> - Physical activity may be important in deterring the obesity epidemic. This study aimed to determine whether objectively measured physical activity in first year of upper secondary high school predicted changes in body composition over 2 years of follow-up in a cohort of Norwegian adolescents (n=431).<p> <p><i>Design</i> - A longitudinal study of adolescents (mean age of 16 (SD ...

    • Prevalence of accelerometer-measured physical activity in adolescents in Fit Futures – part of the Tromsø Study 

      Beldo, Sigurd; Morseth, Bente; Christoffersen, Tore; Halvorsen, Peder Andreas; Hansen, Bjørge Hermann; Furberg, Anne-Sofie; Ekelund, Ulf; Horsch, Alexander (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-17)
      <i>Background</i> - Previous studies show large variations in physical activity (PA) levels among adolescents. However, the number of studies is limited and even fewer studies have assessed PA in adolescents by accelerometer devices. This study aimed to describe accelerometer-measured PA levels in adolescents in a population-based cohort in Northern Norway.<p> <p><i>Methods</i> - In 611 students ...
