    • Epidemiologisk atrieflimmerforskning i Tromsøundersøkelsen. Hva har vi lært? 

      Løchen, Maja-Lisa; Tiwari, Sweta (Journal article; Tidsskriftartikkel; Peer reviewed, 2019)
      Tromsøundersøkelsen er Norges lengste, mest omfattende og best besøkte epidemiologiske befolkningsundersøkelse gjennom mer enn 40 år. Forskningen har gitt oss viktig kunnskap om helse og sykdom og bidrar til bedre pasientbehandling, nasjonalt og internasjonalt. Atrieflimmerforskning har bidratt til ny kunnskap om utbredelse og risikofaktorer.

    • Advancing alcohol Research in low-income and middle-income countries: a global alcohol environment framework 

      Walls, Helen; Cook, Sarah Anne; Matzopolous, Richard; London, Leslie (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-16)
      Alcohol-related harm has gained increased attention in high-income countries (HICs) in recent years which, alongside government regulation, has effected a reduction in alcohol consumption. The alcohol industry has turned its attention to low-income and middle-income country (LMIC) markets as a new source of growth and profit, prompting increased consumption in LMICS. Alcohol use in LMICs is also ...

      Pancreatic cancer (PC) is a highly fatal cancer with currently limited opportunities for early detection and effective treatment. Modifiable factors may offer pathways for primary prevention. In this study, the association between the Healthy Lifestyle Index (HLI) and PC risk was examined. Within the European Prospective Investigation into Cancer and Nutrition cohort, 1113 incident PC (57% women) ...

(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-28)
      Growing epidemiologic evidence supports chronic inflammation as a mechanism of ovarian carcinogenesis. An association between a circulating marker of inflammation, C-reactive protein (CRP), and ovarian cancer risk has been consistently observed, yet, potential heterogeneity of this association by tumor and patient characteristics has not been adequately explored. In this study, we pooled data from ...

A large international trial documented that Internet-based training in CRP point-of-care testing, in enhanced communication skills, or both reduced antibiotic prescribing at 3 months, with risk ratios (RRs) of 0.68, 0.53, 0.38, respectively. We report the longer-term impact in this ...

    • Global test for high-dimensional mediation: Testing groups of potential mediators 

      Djordjilovic, Vera; Page, Christian Magnus; Gran, Jon Michael; Nøst, Therese Haugdahl; Sandanger, Torkjel M; Veierød, Marit Bragelien; Thoresen, Magne (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-05-09)
      We address the problem of testing whether a possibly high‐dimensional vector may act as a mediator between some exposure variable and the outcome of interest. We propose a global test for mediation, which combines a global test with the intersection‐union principle. We discuss theoretical properties of our approach and conduct simulation studies that demonstrate that it performs equally well or ...

      Evidence suggests an influence of sex hormones on cutaneous melanoma risk, but epidemiologic findings are conflicting. We examined the associations between use of oral contraceptives (OCs) and menopausal hormone therapy (MHT) and melanoma risk in women participating in the European Prospective Investigation into Cancer and Nutrition (EPIC). EPIC is a prospective cohort study initiated in 1992 in 10 ...
    • Women Who Trade Sexual Services from Men: A Systematic Mapping Review 

      Berg, Rigmor; Molin, Sol-Britt; Nanavati, Julie (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-02)
      Most research on transactional sex frame men as buyers and females as sellers of sex. We conducted a systematic mapping review of the empirical research on transactional sex where women form the demand (buyer) and men the supply (seller). We included 46 studies, of which 25 explicitly researched women as buyers of sex from male sellers, and 21 studies where this topic was a subset of larger topics. ...

(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-07-26)
      <i>Background & Aims</i> - Colorectal cancer located at different anatomical subsites may have distinct etiologies and risk factors. Previous studies that have examined this hypothesis have yielded inconsistent results, possibly because most studies have been of insufficient size to identify heterogeneous associations with precision.<p><p> <i>Methods</i> - In the European Prospective Investigation ...
