    • The association of grip strength from midlife onwards with all-cause and cause-specific mortality over 17 years of follow-up in the Tromsø Study 

      Strand, Bjørn Heine; Cooper, Rachel; Bergland, Astrid; Jørgensen, Lone; Schirmer, Henrik; Skirbekk, Vegard; Emaus, Nina (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-25)
      <b>Background</b> Grip strength has consistently been found to predict all-cause mortality rates. However, few studies have examined cause-speci fi c mortality or tested age differences in these associations. <b>Methods</b> In 1994, grip strength was measured in the population-based Tromsø Study, covering the ages 50 – 80 years (N=6850). Grip strength was categorised into fi fths, and ...

      Winther, Anne; Jørgensen, Lone; Ahmed, Luai A.; Christoffersen, Tore; Furberg, Anne-Sofie; Grimnes, Guri; Jorde, Rolf; Nilsen, Ole-Andreas; Dennison, Elaine M.; Emaus, Nina (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-19)
      <p><i>Background</i>: Positive association between body weight and bone mass is well established, and the concept of body mass index (BMI) is associated with higher areal bone mineral density (aBMD) and reduced fracture risk. BMI, that comprises both fat mass (FM) and lean mass (LM) may contribute to peak bone mass achievement in different ways. This study explored the influence of body composition ...

    • Fragile bones in patients with stroke? : bone mineral density in acute stroke patients and changes during one year of follow up 

      Jørgensen, Lone (Doctoral thesis; Doktorgradsavhandling, 2001)
      This thesis highlights several clinically important questions related to bone loss the first year following stroke and with regard to bone mass at stroke onset:<br> Lack of mobility and weight bearing early after stroke is an important factor for the greater bone loss in the proximal femur on the paretic side. Relearning to walk within the first two month after stroke, even with support of another ...

    • The phosphodiesterase 8B gene rs4704397 is associated with thyroid function, risk of myocardial infarction and body height. The Tromsø Study 

      Jorde, Rolf; Schirmer, Henrik; Wilsgaard, Tom; Joakimsen, Ragnar Martin; Mathiesen, Ellisiv B.; Njølstad, Inger; Løchen, Maja-Lisa; Figenschau, Yngve Anton; Svartberg, Johan; Hutchinson, Moira Strand; Kjærgaard, Marie; Jørgensen, Lone; Grimnes, Guri (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Objective: High serum thyrotropin (TSH) levels predict cardiovascular disease (CVD). Recently several single nucleotide polymorphisms (SNPs) associated with TSH levels have been identified, one of them being the rs4704397 SNP in the phosphodiesterase 8B (PDE8B) gene. If the relation between thyroid function and CVD is causal, one could also expect rs4704397 genotypes to predict CVD and possibly ...

    • Physical activity and bone : the importance of the various mechanical stimuli for bone mineral density : a review 

      Morseth, Bente; Emaus, Nina; Jørgensen, Lone (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      Numerous studies have reported benefits of regular physical activity on bone mineral density (BMD).
