Passive Smoking’s Effect on Children and Allergies

A new study on passive smoking and its negative effects on children indicate that damage varies according to the children’s age.

A propensity to asthma has been linked to tobacco smoke exposure during pregnancy, whilst allergies have been connected to exposure during the first few years of life.

According to a new doctorate thesis from Karolinska Institute, 4000 children from Stockholm were investigated in what is one of the world’s largest studies of allergies.

Children whose parents smoked during pregnancy were twice at risk of developing asthma before the age of four. Children exposed to smoking after their birth suffered more allergies than children from smoke-free homes.

The strongest link was established between passive smoking and an allergy to cats.
