      Objective Although metabolic profiles have been associated with chronic disease risk, lack of temporal stability of metabolite levels could limit their use in epidemiological investigations. The present study aims to evaluate the reliability over a two-year period of 158 metabolites and compare reliability over time in fasting and non-fasting serum samples. <p>Methods Metabolites were measured ...

      Borch, Kristin Benjaminsen; Weiderpass, Elisabete; Braaten, Tonje; Hansen, Merethe Selnes; Licaj, Idlir (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-01)
      We aimed to investigate physical activity (PA) and risk of different histological subtypes of lung cancer according to smoking status and body mass index using repeated measurements in a large cohort of women in Norway. The study sample for the multiple imputation analyses consisted of 86,499 and for the complete-case analysis 80,802 women. Repeated measurements of PA level, smoking habits, weight, ...

      Whether women are more susceptible than men to smoking-related lung cancer has been a topic of controversy. To address this question, we compared risks of lung cancer associated with smoking by sex. Altogether, 585,583 participants from 3 Norwegian cohorts (Norwegian Counties Study, 40 Years Study, and Cohort of Norway (CONOR) Study) were followed until December 31, 2013, through linkage of data to ...

      Purpose - Sexual health (SH) is an emerging concern in the assessment of quality of life in patients surviving head and neck cancer (HNC). Using data from the French National Prospective VICAN Survey, this study aimed to assess SH deterioration five years after HNC diagnosis and related factors.<p> <p>Methods - Using univariate and multivariate analyses were performed in the 241 HNC survivors. ...
    • Smoking and risk of ovarian cancer by histological subtypes: an analysis among 300 000 Norwegian women.

      Background: We prospectively investigated the association between different measures of smoking exposure and the risk of serous, mucinous, and endometrioid ovarian cancers (OC) in a cohort of more than 300 000 Norwegian women. <br>Methods: We followed 300 398 women aged 19–67 years at enrolment until 31 December 2013 for OC incidence through linkage to national registries. We used Cox proportional ...
    • Smoking related lung cancer mortality by education and sex in Norway 

      Hansen, Merethe Selnes; Licaj, Idlir; Braaten, Tonje; Langhammer, Arnulf; Marchand, Loic Le; Gram, Inger Torhild (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-21)
      Lung cancer is one of the most common forms of cancer and the leading cause of cancer death worldwide, with tobacco smoking as the main cause [1]. In Norway, as in other western countries, smoking was more prevalent among men and in the highest social classes six to seven decades ago [2]. The proportion of male smokers increased until the 1960s, when it was around 65%. Among women, the peak (35%) ...
