      Aims: This paper describes the history, purpose, data collection and contributions in the research collaboration Norwegian Osteoporosis Epidemiologic Studies (NOREPOS). <br>Methods: NOREPOS encompasses almost 85,000 bone mineral density measurements within Cohort of Norway and data on almost 140,000 hip fractures in Norway 1994–2008. Included are anthropometric measurements, blood pressure, ...
    • Impact of total hip replacements on the incidence of hip fractures in Norway during 1999-2019. A NOREPOS study 

      Kjeldgaard, Helena Kames; Meyer, Haakon E.; O’Flaherty, Martin; Apalset, Ellen Margrete; Dahl, Cecilie; Emaus, Nina; Fenstad, Anne Marie; Furnes, Ove; Gjertsen, Jan-Erik; Hoff, Mari; Schei, Berit; Søgaard, Anne-Johanne; Tell, Grethe S.; Holvik, Kristin (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-07-25)
      The knowledge about why hip fracture rates in Norway have declined is sparse. Concurrent with decreasing hip fracture rates, the rates of total hip replacements (THRs) have increased. We wanted to investigate if hip fracture rates continued to decline, and whether the increase in THRs had any influence on this decline, assuming that living with a hip prosthesis precludes fracture of the operated ...
    • 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; Tidsskriftartikkel; Peer reviewed, 2013-08-01)
      <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 ...
    • Urban–Rural Differences in Hip Fracture Mortality: A Nationwide NOREPOS Study 

      Solbakken, Siri Marie; Magnus, Jeanette H.; Meyer, Haakon E; Dahl, Cecilie; Stigum, Hein; Søgaard, Anne-Johanne; Holvik, Kristin; Tell, Grethe S.; Emaus, Nina; Forsmo, Siri; Gjesdal, Clara Gram; Schei, Berit; Vestergaard, Peter; Omsland, Tone Kristin (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-09)
      Higher hip fracture incidence in urban than in rural areas has been demonstrated, but urban–rural differences in posthip fracture mortality have been less investigated, and the results are disparate. Hence, the aims of the present register‐based cohort study were to examine possible urban–rural differences in short‐ and long‐term mortality in Norwegian hip fracture patients and their potential ...
