    • Maternal Smoking in Pregnancy and Offspring Depression: A cross cohort and negative control study 

      Taylor, Amy E; Carslake, David; De Mola, Christian Loret; Rydell, Mina; Nilsen, Tom Ivar Lund; Bjørngaard, Johan Håkon; Horta, Bernardo Lessa; Pearson, Rebecca; Rai, Dheeraj; Galanti, Maria Rosaria; Barros, Fernando C.; Romundstad, Pål Richard; Davey Smith, George; Munafo, Marcus R (Journal article; Peer reviewed, 2017)
      Previous reports suggest that offspring of mothers who smoke during pregnancy have greater risk of developing depression. However, it is unclear whether this is due to intrauterine effects. Using data from the Avon ...
    • Stratification by smoking status reveals an association of CHRNA5-A3-B4 genotype with body mass index in never smokers

      We previously used a single nucleotide polymorphism (SNP) in the CHRNA5-A3-B4 gene cluster associated with heaviness of smoking within smokers to confirm the causal effect of smoking in reducing body mass index (BMI) in a ...
