Abstract

Exposure to environmental tobacco smoke (ETS) has been established as a significant risk factor for respiratory symptoms and diseases in children. However, it is unclear whether the effects of childhood exposure to ETS track into adult life. By using data from the long-term population-based cohort of the TESAOD study, this study found that parental ETS exposure in childhood significantly increases the risk of persistent cough, chronic cough, and wheeze into young adult life.
