• Effects of vitamin D supplementation on bone turnover markers and other bone-related substances in subjects with vitamin D deficiency 

      Jorde, Rolf; Stunes, Astrid Kamilla; Kubiak, Julia Magdalena; Joakimsen, Ragnar Martin; Grimnes, Guri; Thorsby, Per Medbøe; Syversen, Unni (Journal article; Peer reviewed, 2019)
      In observational studies, vitamin D deficiency is a risk factor for low bone density and future fractures, whereas a causal relation has been difficult to show in randomized controlled trials (RCTs). Similarly, vitamin D ...
    • Individual Variation in Adaptive Immune Responses and Risk of Hip Fracture-A NOREPOS Population-Based Cohort Study 

      Dahl, Jesper; Holvik, Kristin; Heldal, Einar; Grimnes, Guri; Hoff, Mari; Finnes, Trine; Apalset, Ellen Margrete; Meyer, Haakon E (Journal article; Peer reviewed, 2020)
      Immune‐mediated bone loss significantly impacts fracture risk in patients with autoimmune disease, but to what extent individual variations in immune responses affect fracture risk on a population level is unknown. To ...
    • Low Serum Levels of 25-Hydroxyvitamin D Predict Hip Fracture in the Elderly: A NOREPOS Study 

      Holvik, Kristin; Ahmed, Luai Awad; Forsmo, Siri; Gjesdal, Clara Gram; Grimnes, Guri; Samuelsen, Sven Ove; Schei, Berit; Blomhoff, Rune; Tell, Grethe S; Meyer, Haakon E (Journal article; Peer reviewed, 2013)
      Background: Despite considerable interest, the relationship between circulating 25-hydroxyvitamin D and the risk of hip fracture is not fully established. Objective: The objective of the study was to study the association ...
    • Smoking and other determinants of bone turnover 

      Jorde, Rolf; Stunes, Astrid Kamilla; Kubiak, Julia Magdalena; Grimnes, Guri; Thorsby, Per Medbøe; Syversen, Unni (Journal article; Peer reviewed, 2019)
      The balance between bone resorption and formation may be assessed by measurement of bone turnover markers (BTMs), like carboxyl-terminal cross-linked telopeptide of type 1 collagen (CTX-1) and procollagen type 1 amino-terminal ...
    • The influence of birth weight and length on bone mineral density and content in adolescence: The Tromsø Study, Fit Futures 

      Christoffersen, Tore; Ahmed, Luai A.; Daltveit, Anne Kjersti; Dennison, Elaine; Evensen, Elin; Furberg, Anne-Sofie; Gracia-Marco, Luis; Grimnes, Guri; Nilsen, Ole-Andreas; Schei, Berit; Tell, Grethe S.; Vlachopoulous, Dimitris; Winther, Anne; Emaus, Nina (Journal article; Peer reviewed, 2017)
      Summary The influence of birth weight and length on bone mineral parameters in adolescence is unclear. We found a positive association between birth size and bone mineral content, attenuated by lifestyle factors. This ...
