      Borch, Kristin Benjaminsen; Eliassen, Bent Martin; Melhus, Marita; Damsgård, Elin; Broderstad, Ann Ragnhild (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-14)
      Background - The Sami people is an indigenous minority population living in the northern parts of Norway and mainly in rural areas. We lack data of contemporary levels of physical activity (PA) in rural regions of Northern Norway and in the Sami population in particular. We aimed to describe the PA levels and investigate whether PA levels differs between Sami and non-Sami and between coastal and ...
    • Complex lifestyle intervention among inactive older adults with elevated cardiovascular disease risk and obesity: a mixed-method, single-arm feasibility study for RESTART—a randomized controlled trial

    • Integrative, multi-omics, analysis of blood samples improves model predictions: applications to cancer 

      Ponzi, Erica; Thoresen, Magne; Haugdahl Nøst, Therese; Møllersen, Kajsa (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-05)
      <i>Background</i> - Cancer genomic studies often include data collected from several omics platforms. Each omics data source contributes to the understanding of the underlying biological process via source specific (“individual”) patterns of variability. At the same time, statistical associations and potential interactions among the different data sources can reveal signals from common biological ...

Further safe reductions may be possible.<br><br> <i>Aim</i> - To investigate the associations between presenting features and antibiotic prescribing in patients with ...
    • Historical perspectives on using sham acupuncture in acupuncture clinical trials 

      Birch, Stephen; Lee, Myeong Soo; Kim, Tae-Hun; Alræk, Terje (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-02)
      <i>Background</i> - Trials of acupuncture in the West began before textbooks about acupuncture were generally available. This placed trials at risk of possible faulty assumptions about the practice of acupuncture and adoption of problematic research assumptions and methods. Further, this lack of information has had an influence on the theories of developing a valid and reliable sham control treatment ...

We included randomized or quasirandomized controlled trials that evaluated the use of any type of ginseng as a treatment for erectile dysfunction compared to placebo or conventional treatment. ...
    • Validity and responsiveness of EQ-5D-5L and SF-6D in patients with health complaints attributed to their amalgam fillings: a prospective cohort study of patients undergoing amalgam removal 

      Lamu, Admassu N.; Björkman, Lars; Hamre, Harald Johan; Alræk, Terje; Musial, Frauke; Robberstad, Bjarne (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-17)
      <i>Background</i> - Evidence of health utility changes in patients who suffer from longstanding health complaints attributed to dental amalgam fillings are limited. The change in health utility outcomes enables calculating quality-adjusted life-year (QALY) and facilitates the comparison with other health conditions. The purpose of this study was to estimate the validity and responsiveness of the ...

    • Religion and Health in Arctic Norway–the association of religious and spiritual factors with suicidal behaviour in a mixed Sámi and Norwegian adult population - The SAMINOR 2 Questionnaire Survey 

      Kiærbech, Henrik; Silviken, Anne; Lorem, Geir F; Kristiansen, Roald E; Spein, Anna Rita (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-12)
      Given the higher suicide rates among the adult population in the northernmost part of Norway and some unfavourable psychosocial outcomes associated with the Laestadian revival movement in this region, it is reasonable to investigate the relationship between religiosity/spirituality and suicidal behaviour in this context. This study used cross-sectional data from the population-based SAMINOR 2 ...
    • Lifestyle changes among people with type 2 diabetes are associated with participation in online groups and time since diagnosis 

      Hansen, Anne Helen; Wangberg, Silje C.; Årsand, Eirik (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-12)
      <i>Background</i> - For people with Type 2 diabetes (T2D), lifestyle changes may be the most effective intervention. Online groups for people with diabetes holds a great potential to support such changes. However, little is known about the association between participation in online groups and lifestyle changes based on internet information in people with T2D. The aim of this study was to investigate ...
