    • Does the frequency and intensity of physical activity in adolescence have an impact on bone? The Tromsø Study, Fit Futures 

      Christoffersen, Tore; Winther, Anne; Nilsen, Ole-Andreas; Ahmed, Luai Awad; Furberg, Anne-Sofie; Grimnes, Guri; Dennison, Elaine; Emaus, Nina (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-11-10)
      Background: Optimization of the genetic potential for bone accrual in early life may prevent future fractures. Possible modification factors include lifestyle factors such as nutrition and physical activity. Measured levels of bone mineral density (BMD) and bone mass content (BMC) are indicators of bone strength, and are correlated with fracture risk. This study explored the impact of self-reported ...

Fracture rates correspond with other reports from Scandinavia, although with a slightly higher proportion in girls. Indications of increased vulnerability during stages of puberty require further exploration. <p>Introduction: Fractures are common injuries during ...

      <p>Objectives: Low levels of physical activity may have considerable negative effects on bone health in adolescence, and increasing screen time in place of sporting activity during growth is worrying. This study explored the associations between self-reported screen time at weekends and bone mineral density (BMD). <p>Design: In 2010/2011, 1038 (93%) of the region’s first-year upper-secondary ...

      <p><i>Background</i>: Despite considerable interest, the relationship between circulating 25-hydroxyvitamin D and the risk of hip fracture is not fully established.</p> <p><i>Objective</i>: The objective of the study was to study the association between serum 25-hydroxyvitamin D concentrations [s-25(OH)D] and the risk of hip fracture in Norway, a high-latitude country that has some of the highest ...

    • 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 ...

    • Musculoskeletal complaints (pain and/or stiffness) and their impact on mortality in the general population. The Tromsø study 

      Andorsen, Ole Fredrik; Ahmed, Luai Awad; Emaus, Nina; Klouman, Elise (Journal article; Tidsskriftartikkel; Peer reviewed, 2016)
      Background The long-term consequences of chronic pain and/or stiffness from the musculoskeletal system (musculoskeletal complaints: MSCs) have not been well explored. The aims of this study were to investigate whether MSCs reported at baseline influence all-cause and cause-specific mortality during 21 years follow-up of a general Northern Norwegian adult population. Methods A total of 26,977 ...

    • Risk factors for fractures in Tromsø : the Tromsø study 

      Ahmed, Luai Awad (Doctoral thesis; Doktorgradsavhandling, 2005)
      <p>A fracture is a break or crack in a bone. Fractures are common and anyone can fracture a bone. They occur when the bone can not withstand the physical force excerpted on it. There are several types or classifications of fracture; simple, stress, comminuted, impact, compound, complete and incomplete. Depending on the type and location of a fracture, the treatment varies from immobilization ...
