    • Using Fitness Trackers and Smartwatches to Measure Physical Activity in Research: Analysis of Consumer Wrist-Worn Wearables 

      Henriksen, André; Mikalsen, Martin Haugen; Woldaregay, Ashenafi Zebene; Muzny, Miroslav; Hartvigsen, Gunnar; Hopstock, Laila Arnesdatter; Grimsgaard, Sameline (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-22)
      Background: New fitness trackers and smartwatches are released to the consumer market every year. These devices are equipped with different sensors, algorithms, and accompanying mobile apps. With recent advances in mobile sensor technology, privately collected physical activity data can be used as an addition to existing methods for health data collection in research. Furthermore, data collected ...

    • Using mobile sensors to expand recording of physical activity and increase motivation for prolonged data sharing in a population-based study 

      Henriksen, André; Hartvigsen, Gunnar; Hopstock, Laila Arnesdatter; Grimsgaard, Sameline (Journal article; Tidsskriftartikkel; Peer reviewed, 2017)
      Regularly conducted population cohort studies contribute important new knowledge to medical research. A high participation rate is required in these types of studies in order to claim representativeness and validity of study results. Participation rates are declining worldwide, and re-searchers are challenged to develop new data collection strategies and tools to motivate people to participate. The ...

    • Utvikling av indikatorer på NCD området knyttet til rapportering for den globale og nasjonale NCD strategien 

      Ariansen, Inger; Nystad, Wenche; Graff-Iversen, Sidsel; Gulseth, Hanne Løvdal; Meyer, Haakon E; Brunborg, Geir Scott; Vedøy, Tord Finne; Vollset, Stein Emil; Reneflot, Anne; Nerhus, Kjersti Andersen; Henrichsen, Svein Høegh; Huseby, Beate Margrethe; Nylenna, Astrid; Anderssen, Sigmund Alfred; Ekelund, Ulf; Krokstad, Steinar; Møller, Bjørn; Weiderpass, Elisabete; Tell, Grethe S.; Gram, Inger Torhild; Grimsgaard, Sameline; Njølstad, Inger; Bakke, Per; Husebø, Gunnar (Research report; Forskningsrapport, 2017-04)
      Norge har sluttet seg til WHO sitt mål om 25% reduksjon 2010 til 2025 i for tidlig død som følge av de fire ikke-smittsomme sykdommene (noncommunicale disease, NCD); kreft, hjerte- og karsykdom, diabetes og kronisk lungesykdom. Bakgrunnen er at disse fire sykdomsgruppene langt på vei kan forebygges ved å redusere de fire felles risikofaktorene røyking, usunn kost, stillesitting og skadelig bruk ...

    • Validating Acute Myocardial Infarction Diagnoses in National Health Registers for Use as Endpoint in Research: The Tromsø Study 

      Varmdal, Torunn; Mathiesen, Ellisiv B.; Wilsgaard, Tom; Njølstad, Inger; Nyrnes, Audhild; Grimsgaard, Sameline; Bønaa, Kaare Harald; Mannsverk, Jan; Løchen, Maja-Lisa (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-03)
      <i>Purpose</i>: To assess whether acute myocardial infarction (MI) diagnoses in national health registers are sufficiently correct and complete to replace manual collection of endpoint data for a population-based, epidemiological study.<br><br> <i>Patients and Methods</i>: Using the Tromsø Study Cardiovascular Disease Register for 2013– 2014 as gold standard, we calculated correctness (defined ...

    • Validity of the Polar M430 Activity Monitor in Free-Living Conditions: Validation Study 

      Henriksen, André; Grimsgaard, Sameline; Horsch, Alexander; Hartvigsen, Gunnar; Hopstock, Laila Arnesdatter (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-16)
      <i>Background</i>: Accelerometers, often in conjunction with heart rate sensors, are extensively used to track physical activity (PA) in research. Research-grade instruments are often expensive and have limited battery capacity, limited storage, and high participant burden. Consumer-based activity trackers are equipped with similar technology and designed for long-term wear, and can therefore ...
