    • Interaction between gas cooking and GSTM1 null genotype in bronchial responsiveness: Results from the European Community Respiratory Health Survey 

      Amaral, André F.S.; Ramasamy, Adaikalavan; Castro-Giner, Francesc; Minelli, Cosetta; Accordini, Simone; Sørheim, Inga Cecilie; Pin, Isabelle; Kogevinas, Manolis; Jõgi, Rain; Balding, David J.; Norbäck, Dan; Verlato, Guiseppe; Olivieri, Mario; Probst-Hensch, Nicole; Janson, Christer; Zock, Jan-Paul; Heinrich, Joachim; Jarvis, Deborah L. (Peer reviewed; Journal article, 2014)
      Background: Increased bronchial responsiveness is characteristic of asthma. Gas cooking, which is a major indoor source of the highly oxidant nitrogen dioxide, has been associated with respiratory symptoms and reduced lung ...
    • Longterm follow-up in European respiratory health studies - patterns and implications 

      Johannessen, Ane; Verlato, Guiseppe; Benediktsdottir, Bryndis; Forsberg, Bertil; Franklin, Karl; Gíslason, Thorainn; Holm, Mathias; Janson, Christer; Jögi, Rain; Lindberg, Eva; Macsali, Ferenc; Omenaas, Ernst; Gomez Real, Francisco; Saure, Eirunn Waatevik; Schlünssen, Vivi; Sigsgaard, Torben; Skorge, Trude Duelien; Svanes, Cecilie; Torén, Kjell; Waatevik, Marie Johanne; Nilsen, Roy Miodini; de Marco, Roberto (Peer reviewed; Journal article, 2014-04-16)
      Background: Selection bias is a systematic error in epidemiologic studies that may seriously distort true measures of associations between exposure and disease. Observational studies are highly susceptible to selection ...
    • Parents’ smoking onset before conception as related to body mass index and fat mass in adult offspring: Findings from the RHINESSA generation study 

      Knudsen, Gerd Toril Mørkve; Dharmage, Shyamali C.; Janson, Christer; Abramson, Michael J.; Benediktsdóttir, Bryndís; Malinovschi, Andrei; Skulstad, Svein Magne; Bertelsen, Randi Jacobsen; Real, Francisco Gomez; Schlünssen, Vivi; Jögi, Nils Oskar; Sánchez-Ramos, José Luis; Holm, Mathias; Garcia-Aymerich, Judith; Forsberg, Bertil; Svanes, Cecilie; Johannessen, Ane (Journal article; Peer reviewed, 2020)
      Emerging evidence suggests that parents’ preconception exposures may influence offspring health. We aimed to investigate maternal and paternal smoking onset in specific time windows in relation to offspring body mass index ...
    • Pharmacological treatment of asthma in a cohort of adults during a 20-year period: results from the European Community Respiratory Health Survey I, II and III
