      Sun, Yi-Qian; Brumpton, Ben Michael; Langhammer, Arnulf; Chen, Yue; Kvaløy, Kirsti; Mai, Xiao-Mei (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-14)
      <i>Background</i> - We aimed to investigate the potential causal associations of adiposity with asthma overall, asthma by atopic status or by levels of symptom control in a large adult population and stratified by sex. We also investigated the potential for reverse causation between asthma and risk of adiposity.<p> <p><i>Methods</i> - We performed a bidirectional one-sample Mendelian randomisation ...

      Sun, Yi-Qian; Richmond, Rebecca C.; Suderman, Matthew; Min, Josine L; Battram, Thomas; Flatberg, Arnar; Beisvag, Vidar; Nøst, Therese Haugdahl; Guida, Florence; Jiang, Lin; Wahl, Sissel Gyrid Freim; Langhammer, Arnulf; Skorpen, Frank; Walker, Rosie M; Bretherick, Andrew D; Zeng, Yanni; Chen, Yue; Johansson, Mattias; Sandanger, Torkjel M; Relton, Caroline L; Mai, Xiao-Mei (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-17)
      <i>Background</i> - It is unclear if smoking-related DNA methylation represents a causal pathway between smoking and risk of lung cancer. We sought to identify novel smoking-related DNA methylation sites in blood, with repeated measurements, and to appraise the putative role of DNA methylation in the pathway between smoking and lung cancer development.<br><br> <i>Methods</i> - We derived a nested ...

      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, ...

    • Sex differences in risk of smoking-related lung cancer: results from a cohort of 600,000 Norwegians 

      Hansen, Merethe Selnes; Licaj, Idlir; Braaten, Tonje; Langhammer, Arnulf; Marchand, Loic Le; Gram, Inger Torhild (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-10-26)
      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 ...
    • 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%) ...

      Background: Self-reported atrial fibrillation (AF) and diagnoses from hospital registers are often used to identify persons with AF. The objective of this study was to validate self-reported AF and hospital discharge diagnoses of AF among participants in a population-based study.
