      Forsdahl, Signe Helene; Solberg, Steinar; Singh, Kulbir; Jacobsen, Bjarne Koster (Journal article; Tidsskriftartikkel; Peer reviewed, 2010)
      Background: In a population-based study in Tromsø, Norway, the authors assessed whether an abdominal aortic aneurysm (AAA) or the maximal infrarenal aortic diameter in a non-aneurismal aorta influence total and cardiovascular disease (CVD) mortality. Methods: A total of 6640 men and women, aged 25–84 years, were included in a 10-year mortality follow-up: 345 subjects with a diagnosed AAA and ...
    • Active and passive smoking and the risk of myocardial infarction in 24,968 men and women during 11 year of follow-up: the Tromsø Study 

      Iversen, Birgitte; Jacobsen, Bjarne Koster; Løchen, Maja-Lisa (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Active smoking is a well-established risk factor for myocardial infarction, but less is known about the impact of passive smoking, and possible sex differences in risk related to passive smoking. We investigated active and passive smoking as risk factors for myocardial infarction in an 11-year follow-up of 11,762 men and 13,206 women included in the Tromsø Study. There were a total of 769 and 453 ...
    • Anthropometric measures are satisfactory substitutes for the DXA‐derived visceral adipose tissue in the association with cardiometabolic risk—The Tromsø Study 2015–2016 

      Lundblad, Marie Wasmuth; Jacobsen, Bjarne Koster; Johansson, Jonas; Grimsgaard, Sameline; Andersen, Lene Frost; Hopstock, Laila Arnesdatter (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-03)
      Background - Body mass index (BMI) increases while cardiometabolic risk factors decrease in individuals in high-income countries. This paradoxical observation raises the question of whether current measures of overweight and obesity properly identify cardiometabolic risk.<p> <p>Methods - A total of 3675 participants (59% women) aged 40–84 years with whole-body dual-energy x-ray absorptiometry ...
    • Body mass index and mortality in elderly men and women: the Tromso and HUNT studies
