      Mathisen, Therese Fostervold; Rosenvinge, Jan H; Friborg, Oddgeir; Pettersen, Gunn; Stensrud, Trine; Hansen, Bjørge Hermann; Underhaug, Karoline; Teinung, Elisabeth; Vrabel, KariAnne; Svendsen, Mette; Bratland-Sanda, Solfrid; Sundgot-Borgen, Jorunn (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-23)
      <p><i>Objective</i>: Knowledge about physical fitness in women with bulimia nervosa (BN) or binge‐eating disorder (BED) is sparse. Previous studies have measured physical activity largely through self‐report, and physical fitness variables are mainly restricted to body mass index (BMI) and bone mineral density. We expanded the current knowledge in these groups by including a wider range of physical ...

    • Criterion validity of the Saltin-Grimby Physical Activity Level Scale in adolescents. The Fit Futures Study 

      Beldo, Sigurd Klemetsen; Aars, Nils Abel; Christoffersen, Tore; Furberg, Anne-Sofie; Halvorsen, Peder Andreas; Hansen, Bjørge Hermann; Horsch, Alexander; Sagelv, Edvard Hamnvik; Syed, Shaheen; Morseth, Bente (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-01)
      Background<p> <p>The Saltin-Grimby Physical Activity Level Scale (SGPALS) is commonly used to measure physical activity (PA) in population studies, but its validity in adolescents is unknown. This study aimed to assess the criterion validity of the SGPALS against accelerometry in a large sample of adolescents. A secondary aim was to examine the validity across strata of sex, body mass index (BMI), ...

    • Criterion validity of two physical activity and one sedentary time questionnaire against accelerometry in a large cohort of adults and older adults 

      Sagelv, Edvard Hamnvik; Hopstock, Laila Arnesdatter; Johansson, Jonas; Hansen, Bjørge Hermann; Søren, Brage; Horsch, Alexander; Ekelund, Ulf; Morseth, Bente (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-02-26)
      <i>Objectives</i> - We compared the ability of physical activity and sitting time questionnaires (PAQ) for ranking individuals versus continuous volume calculations (physical activity level (PAL), metabolic equivalents of task (MET), sitting hours) against accelerometry measured physical activity as our criterion.<p> <p><i>Methods</i> - Participants in a cohort from the Tromsø Study completed ...

    • Daily steps and all-cause mortality: a meta-analysis of 15 international cohorts 

      Paluch, Amanda E; Bajpai, Shivangi; Bassett, David R; Carnethon, Mercedes R; Ekelund, Ulf; Evenson, Kelly R; Galuska, Deborah A; Jefferis, Barbara J; Kraus, William E; Lee, I-Min; Matthews, Charles E; Omura, John D; Patel, Alpa V; Pieper, Carl F; Rees-Punia, Erika; Dallmeier, Dhayana; Klenk, Jochen; Whincup, Peter H; Dooley, Erin E; Pettee Gabriel, Kelley; Palta, Priya; Pompeii, Lisa A; Chernofsky, Ariel; Larson, Martin G; Vasan, Ramachandran S; Spartano, Nicole; Ballin, Marcel; Nordström, Peter; Nordström, Anna Hava; Anderssen, Sigmund Alfred; Hansen, Bjørge Hermann; Cochrane, Jennifer A; Dwyer, Terence; Wang, Jing; Ferrucci, Luigi; Liu, Fangyu; Schrack, Jennifer; Urbanek, Jacek; Saint-Maurice, Pedro F; Yamamoto, Naofumi; Yoshitake, Yutaka; Newton, Robert L; Yang, Shengping; Shiroma, Eric J; Fulton, Janet E (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-22)
      Background Although 10000 steps per day is widely promoted to have health benefits, there is little evidence to support this recommendation. We aimed to determine the association between number of steps per day and stepping rate with all-cause mortality.<p> <p>Methods In this meta-analysis, we identified studies investigating the effect of daily step count on all-cause mortality in adults (aged ...

    • Device-measured physical activity, sedentary time, and risk of all-cause mortality: an individual participant data analysis of four prospective cohort studies 

      Sagelv, Edvard Hamnvik; Hopstock, Laila Arnesdatter; Morseth, Bente; Hansen, Bjørge Hermann; Steene-Johannessen, Jostein; Johansson, Jonas Lars; Nordström, Anna Hava; Saint-Maurice, Pedro F; Løvsletten, Ola; Wilsgaard, Tom; Ekelund, Ulf; Tarp, Jakob (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-24)
      Objectives - To examine whether moderate-to-vigorous physical activity (MVPA) modifies the association between sedentary time and mortality and vice versa, and estimate the joint associations of MVPA and sedentary time on mortality risk.<p> <p>Methods - This study involved individual participant data analysis of four prospective cohort studies (Norway, Sweden, USA, baseline: 2003–2016, 11 989 ...

    • Physical activity levels in adults and elderly from triaxial and uniaxial accelerometry. The Tromsø Study 

      Sagelv, Edvard Hamnvik; Ekelund, Ulf; Pedersen, Sigurd; Brage, Søren; Hansen, Bjørge Hermann; Johansson, Jonas; Grimsgaard, Sameline; Nordström, Anna; Horsch, Alexander; Hopstock, Laila Arnesdatter; Morseth, Bente (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-03)
      <i>Introduction</i> - Surveillance of physical activity at the population level increases the knowledge on levels and trends of physical activity, which may support public health initiatives to promote physical activity. Physical activity assessed by accelerometry is challenged by varying data processing procedures, which influences the outcome. We aimed to describe the levels and prevalence estimates ...

    • 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 ...
