    • The association between timed up and go test and history of falls : The Tromsø study 

      Joakimsen, Ragnar Martin; Thornquist, Eline; Thrane, Gyrd (Journal article; Tidsskriftartikkel; Peer reviewed, 2007-01-12)
      Background: Fall-related injuries in older adults are a major health problem. Although the aetiology of falls is multifactorial, physical factors are assumed to contribute significantly. The "Timed up and go test" (TUG) is designed to measure basic mobility function. This report evaluates the association between TUG times and history of falls. Methods: A retrospective, observational, population-based ...

    • Bone mineral density is associated with Vitamin D related rs6013897 and estrogen receptor polymorphism rs4870044: The Tromsø study 

      Martinaityte, Ieva; Jorde, Rolf; Emaus, Nina; Eggen, Anne Elise; Joakimsen, Ragnar Martin; Kamycheva, Elena (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-03-02)
      Background:<br>Bone mineral density (BMD) is determined by bone remodeling processes regulated by endocrine, autocrine and genetic mechanisms. Thus, some studies have reported that BMD is associated with single nucleotide polymorphisms (SNPs) associated with vitamin D receptor (VDR), serum 25(OH)D levels and estrogen receptor 1 (ESR1), but without consensus. Therefore, we aimed to map and compare ...

    • Measurement of cortical porosity of the proximal femur improves identification of women with nonvertebral fragility fractures 

      Ahmed, Luai Awad; Shigdel, Rajesh; Joakimsen, Ragnar Martin; Eldevik, Odd Petter; Eriksen, Erik Fink; Ghasem-Zadeh, Ali; Bala, Yohann; Zebaze, Roger; Seeman, Ego; Bjørnerem, Åshild (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-04-16)
      Summary We tested whether cortical porosity of the proximal femur measured using StrAx1.0 software provides additional information to areal bone mineral density (aBMD) or Fracture Risk Assessment Tool (FRAX) in differentiating women with and without fracture. Porosity was associated with fracture independent of aBMD and FRAX and identified additional women with fractures than by osteoporosis or ...
