Association between environmental tobacco smoke exposure and wheezing disorders in Austrian preschool children

Abstract

Our study confirms previous studies, that in particular prenatal ETS exposure is a risk factor for wheezing and asthma in preschool children. Despite this, children exposed to ETS also live a "less healthier life" in terms of breast feeding and antioxidant intake. In the light of recent studies reporting increased oxidative stress in children exposed to passive smoking, the low intake of fruits and vegetables is a further concern.
