    • Alcohol consumption, endogenous estrogen and mammographic density among premenopausal women 

      Frydenberg, Hanne; Flote, Vidar Gordon; Larsson, Ine Marie; Barrett, Emily S.; Furberg, Anne-Sofie; Ursin, Giske; Wilsgaard, Tom; Ellison, Peter; McTiernan, Anne; Hjartåker, Anette; Jasienska, Grazyna; Thune, Inger (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-08-07)
      Introduction: Alcohol consumption may promote aromatization of androgens to estrogens, which may partly explain the observations linking alcohol consumption to higher breast cancer risk. Whether alcohol consumption is associated with endogenous estrogen levels, and mammographic density phenotypes in premenopausal women remains unclear.<p> <p>Methods: Alcohol consumption was collected by self-report ...

    • Duration of Lactation, Maternal Metabolic Profile, and Body Composition in the Norwegian EBBA I-Study 

      Tørris, Christine; Thune, Inger; Emaus, A; Finstad, SE; Bye, Asta; Furberg, AS; Barrett, Emily S.; Jasienska, G; Ellison, P; Hjartåker, Anette (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      There is conflicting evidence as to whether duration of lactation may decrease the risk of subsequent development of an unfavorable maternal metabolic profile, including overweight and obesity. We hypothesized that duration of lactation is associated with a more favorable metabolic profile and healthier anthropometric measurements. Ninety-eight parous women were studied from the Norwegian EBBAI-study ...

    • Polymorphisms in the estrogen receptor alpha gene (ESR1), daily cycling estrogen and mammographic density phenotypes 

      Fjeldheim, Frøydis Nyborg; Frydenberg, Hanne; Flote, Vidar Gordon; McTiernan, Anne; Furberg, Anne-Sofie; Ellison, Peter T.; Barrett, Emily S.; Wilsgaard, Tom; Jasienska, Grazyna; Ursin, Giske; Wist, Erik; Thune, Inger (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-10-07)
      Background: Single nucleotide polymorphisms (SNPs) involved in the estrogen pathway and SNPs in the estrogen receptor alpha gene (ESR1 6q25) have been linked to breast cancer development, and mammographic density is an established breast cancer risk factor. Whether there is an association between daily estradiol levels, SNPs in ESR1 and premenopausal mammographic density phenotypes is unknown. Methods: ...
