      Earlier analyses within the EPIC study showed that dietary fibre intake was inversely associated with colorectal cancer risk, but results from some large cohort studies do not support this finding. We explored whether the association remained after longer follow-up with a near threefold increase in colorectal cancer cases, and if the association varied by gender and tumour location. After a mean ...

      Konglevoll, Dina Moxness; Andersen, Lene Frost; Hopstock, Laila Arnesdatter; Strand, Bjørn Heine; Thoresen, Magne; Totland, Torunn Holm; Hjartåker, Anette; Carlsen, Monica Hauger (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-05)
      Background Pre-frailty is an intermediate, potentially reversible state before the onset of frailty. Healthy dietary choices may prevent pre-frailty. Fish is included in most healthy diets, but little is known about the association between long-term habitual fish intake and pre-frailty. We aimed to elucidate the longitudinal association between the frequency of fish intake and pre-frailty in a ...

    • Milk and risk of colorectal, colon and rectal cancer in the Norwegian Women and Cancer (NOWAC) Cohort Study 

      Bakken, Toril; Braaten, Tonje; Olsen, Anja; Hjartåker, Anette; Lund, Eiliv; Skeie, Guri (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-17)
      According to World Cancer Research Fund International/American Institute for Cancer Research, it is ‘probable’ that dairy products decrease the risk of colorectal cancer (CRC). However, meta-analyses restricted to women have not shown associations between milk intake and risk of CRC. The aim of this study was to examine the association between milk intake and risk of CRC, colon cancer and rectal ...

    • Normal and unusual days for dietary intake during the 12 months after a breast cancer diagnosis in women 

      Brunvoll, Sonja Hjellegjerde; Flote, Vidar Gordon; Halset, Eline Holli; Bertheussen, Gro Falkener; Skjerven, Helle; Lømo, Jon; Thune, Inger; Hjartåker, Anette (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-24)
      Purpose There are several reasons to report days as being unusual with regard to dietary intake, including special occasions and celebrations. For breast cancer patients during the 12 month post-surgery period, unusual days may also include days that are afected by being a cancer patient. The aim of this study was to study dietary intake on “normal” and “unusual” days, and to study what is reported ...

    • Regression analysis with categorized regression calibrated exposure. Some interesting findings 

      Dalen, Ingvild; Hjartåker, Anette; Buonaccorsi, John P.; Laake, Petter; Thoresen, Magne (Journal article; Tidsskriftartikkel; Peer reviewed, 2006-07-04)
      Background: Regression calibration as a method for handling measurement error is becoming increasingly well-known and used in epidemiologic research. However, the standard version of the method is not appropriate for exposure analyzed on a categorical (e.g. quintile) scale, an approach commonly used in epidemiologic studies. A tempting solution could then be to use the predicted continuous ...
