      Dalene, Knut Eirik; Lergenmuller, Simon; Sund, Erik Reidar; Hopstock, Laila Arnesdatter; Robsahm, Trude Eid; Nilssen, Yngvar; Nystad, Wenche; Larsen, Inger Kristin; Ariansen, Inger (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-02)
      Noncommunicable diseases (NCDs) are a leading cause of premature death globally and have common preventable risk factors. In Norway, the NCDNOR-project aims at establishing new knowledge in the prevention of NCDs by combining information from national registries with data from populationbased health studies. In the present study, we aimed to harmonize data on key NCD risk factors from the health ...

    • Life-Course Trajectories of Physical Activity and Melanoma Risk in a Large Cohort of Norwegian Women 

      Perrier, Flavie; Ghiasvand, Reza; Lergenmuller, Simon; Robsahm, Trude Eid; Green, Adele C.; Borch, Kristin Benjaminsen; Sandanger, Torkjel M; Weiderpass, Elisabete; Rueegg, Corina Silvia; Veierød, Marit Bragelien (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-22)
      Purpose: Physical activity (PA) is a cornerstone in disease prevention and varies throughout life. A pooled analysis of cohort studies and a meta-analysis of cohort studies found positive associations between PA and melanoma risk. However, previous studies focused on PA at specific ages and often lacked information on ultraviolet radiation (UVR) exposure. Using the population-based Norwegian Women ...

      Meyer, Haakon E; Støer, Nathalie; Samuelsen, Sven Ove; Blomhoff, Rune; Robsahm, Trude Eid; Brustad, Magritt; Giovannucci, Edward L; Bjørge, Tone (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-03-17)

    • National health registries – a ‘goldmine’ for studying non-communicable disease occurrence in Norway – the NCDNOR project 

      Nystad, Wenche; Hjellvik, Vidar; Larsen, Inger Kristin; Robsahm, Trude Eid; Sund, Erik Reidar; Krokstad, Steinar; Hopstock, Laila Arnesdatter; Grimsgaard, Anne Sameline; Langhammer, Arnulf; Bramness, Jørgen Gustav; Wisløff, Torbjørn; Lergenmuller, Simon; Dalene, Knut Eirik; Meyer, Haakon Eduard; Holvik, Kristin; Helgeland, Jon; Karlstad, Øystein; Ariansen, Inger (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-10)
      To estimate occurrence of non-communicable diseases (NCDs) over the life-course in the Norwegian population, national health registries are a vital source of information since they fully represent the entire non-institutionalised population. However, as they are mainly established for administrative purposes, more knowledge about how NCDs are recorded in the registries is needed. To establish this, ...

    • Nevus Count, Pigmentary Characteristics, and Melanoma-specific Mortality among Norwegian Women with Melanoma >1.0 mm Thick 

      Ahimbisibwe, Ashley; Valberg, Morten; Green, Adele C.; Ghiasvand, Reza; Rüegg, Corina Silvia; Rimal, Raju; Weiderpass, Elisabete; Sandanger, Torkjel M; Robsahm, Trude Eid; Veierød, Marit Bragelien (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-04-04)
      Little is known about if and how nevi and pigmentation are associated with melanoma-specific mortality. However, increased melanoma awareness in people with lighter pigmentation and many nevi may result in earlier diagnosis of thinner less-lethal tumors. The aim of this study was to investigate associations between nevus count (asymmetrical > 5 mm and small symmetrical), pigmentary characteristics ...

    • No association between physical activity and primary melanoma thickness in a cohort of Norwegian women 

      Perrier, Flavie; Robsahm, Trude Eid; Ghiasvand, Reza; Borch, Kristin Benjaminsen; Braaten, Tonje; Weiderpass, Elisabete; Rüegg, Corina Silvia; Greene, Adele C; Veierød, Marit Bragelien (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-21)
      Knowledge about factors associated with melanoma thickness, the most important prognostic factor for localized primary melanoma survival,1 may help reduce the risk of melanoma deaths. Previously reported associations of melanoma thickness with pigmentary characteristics, number of naevi, diet quality and body mass index (BMI)2–4 may be explained by behavioural and biological mechanisms. Physical ...

    • Phenotypic Characteristics and Melanoma Thickness in Women. 

      Ghiasvand, Reza; Green, Adele C.; Sandanger, Torkjel M; Weiderpass, Elisabete; Robsahm, Trude Eid; Veierød, Marit Bragelien (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-21)
      Patients’ phenotypic characteristics might be associated with melanoma aggressiveness, but the evidence is scarce. This study examined the associations be­tween pigmentary characteristics, naevi and melanoma thickness. Data from the Norwegian Women and Cancer (NOWAC) study were analysed. By 2014, 1,243 women were diagnosed with a primary melanoma, and 1,140 had information on thickness. Using ordinal ...

    • Physical activity and cutaneous melanoma risk: A Norwegian population-based cohort study 

      Perrier, Flavie; Ghiasvand, Reza; Lergenmuller, Simon; Robsahm, Trude Eid; Green, Adele C.; Borch, Kristin Benjaminsen; Sandanger, Torkjel M; Weiderpass, Elisabete; Rueegg, Corina Silvia; Veierød, Marit Bragelien (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-20)
      Physical activity (PA) is an important factor in cancer prevention, but positive association between PA and risk of cutaneous melanoma found in recent studies may complicate this strategy. Ultraviolet radiation (UVR) exposure during outdoor PA is a plausible explanation for a positive association. We investigated the associations between PA, UVR and melanoma risk in the Norwegian Women and Cancer ...

      Robsahm, Trude Eid; Sagstad, Silje; Thy, Jonas Evensen; Hofvind, Solveig Sand-Hanssen (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-12)
      Purpose: To collect information on sociodemographic factors, health indicators, and lifestyle factors in women who attended the nationwide breast cancer-screening program, BreastScreen Norway, with the aim of investigating how these factors influence the risk of breast cancer, other cancer types, and cancer-related outcomes. <p>Participants: The cohort data includes self-reported responses to ...

    • Sunscreens With High Versus Low Sun Protection Factor and Cutaneous Squamous Cell Carcinoma Risk: A Population-Based Cohort Study 

      Lergenmuller, Simon; Ghiasvand, Reza; Robsahm, Trude Eid; Green, Adèle C.; Lund, Eiliv; Rueegg, Corina Silvia; Veierød, Marit Bragelien (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-11)
      Evidence on sunscreen use and cutaneous squamous cell carcinoma (cSCC) risk is limited. Most studies have not taken sun protection factor (SPF) into consideration and used nonusers of sunscreen as the reference group. Nonusers are likely a priori at lower cSCC risk than users. No study has investigated the effect of high- versus low-SPF sunscreens on cSCC, appropriately adjusting for time-varying ...
