The association between anemia and falls in community-living women and men aged 65 years and older from the fifth Tromsø Study 2001-02: a replication study
Hopstock, Laila Arnesdatter; Utne, Elisabeth Bøe; Horsch, Alexander; Skjelbakken, Tove (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-12-27)Background: <br> Falls are common among elderly people, and the risk increase with age. Falls are associated with both health and social consequences for the patient, and major societal costs. Identification of risk factors should be investigated to prevent falls. Previous studies have shown anemia to be associated with increased risk of falling, but the results are inconsistent. The aim of this ... -

Change in physical activity is not associated with change in mental distress among adolescents: The Tromsø Study: Fit Futures
Opdal, Ida Marie; Morseth, Bente; Handegård, Bjørn Helge; Lillevoll, Kjersti; Ask, Helga; Nielsen, Christopher Sivert; Horsch, Alexander; Furberg, Anne-Sofie; Rosenbaum, Simon; Rognmo, Kamilla (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-09)<i>Background</i>: Previous research shows that physical activity has a protective effect on mental distress in adults, but the relationship is less researched and seems more ambiguous for adolescents. Studies in this field have typically been cross-sectional by design and based on self-reported physical activity measures, which are known to be vulnerable to response bias. The aim of this study ... -
Electronic Symptom Reporting Between Patient and Provider for Improved Health Care Service Quality: A Systematic Review of Randomized Controlled Trials. Part 1: State of the Art
Johansen, Monika Alise; Henriksen, Eva; Horsch, Alexander; Schuster, Tibor; Berntsen, Gro (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)Background: Over the last two decades, the number of studies on electronic symptom reporting has increased greatly. However, the field is very heterogeneous: the choices of patient groups, health service innovations, and research targets seem to involve a broad range of foci. To move the field forward, it is necessary to build on work that has been done and direct further research to the areas holding ... -
Electronic Symptom Reporting Between Patient and Provider for Improved Health Care Service Quality: A Systematic Review of Randomized Controlled Trials. Part 2: Methodological Quality and Effects
Johansen, Monika Alise; Berntsen, Gro; Schuster, Tibor; Henriksen, Eva; Horsch, Alexander (Tidsskriftartikkel; Journal article; Peer reviewed, 2012)Background: We conducted in two parts a systematic review of randomized controlled trials (RCTs) on electronic symptom reporting between patients and providers to improve health care service quality. Part 1 reviewed the typology of patient groups, health service innovations, and research targets. Four innovation categories were identified: consultation support, monitoring with clinician support, ... -
Physical activity and cold pain tolerance in the general population
Årnes, Anders; Nielsen, Christopher Sivert; Stubhaug, Audun; Fjeld, Mats Kirkeby; Hopstock, Laila Arnesdatter; Horsch, Alexander; Johansen, Aslak; Morseth, Bente; Wilsgaard, Tom; Steingrímsdóttir, Ólöf Anna (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-09)<p>Background - The relationship between habitual physical activity (PA) and experimental pain tolerance has been investigated in small samples of young, healthy and/or single‐sex volunteers. We used a large, population‐based sample to assess this relationship in men and women with and without chronic pain. <p>Methods - We used data from the sixth and seventh Tromsø Study surveys (2007–2008; ... -
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 ...
