  3. 3. Tobacco use and dependence : does it originate in utero?

    Författare :Mina Rydell; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Sammanfattning : Prenatal nicotine exposure (such as from maternal smoking during pregnancy) has been hypothesized to cause a so called programming effect, where epigenetic changes might result in a long-lasting vulnerability to tobacco use and dependence, manifesting during adolescence or young adulthood. However, previous observational studies show mixed results, perhaps because the association could be influenced by a common genetic predisposition to tobacco use as well as by social factors influencing both parental tobacco use during pregnancy and tobacco use in the offspring.

    Sammanfattning : Tobacco use is common among people who suffer from depressive symptoms. This cooccurrence is associated with several negative health outcomes. The present thesis will contribute to the understanding of if, how, and in which contexts this specific association occurs in early adolescence. LÄS MER
