American doctors say that
mothers who smoke cigarettes before their babies are born may slow the growth
of their babies’ lungs. They say reduced lung growth could cause the babies to
suffer breathing problems and lung disease later in life. Doctors in Boston, Massachusetts
studied 1,100 children. The mothers of some of the children smoked, the other
mothers did not. Doctors found that the lungs of the children whose mothers did
not smoke, and that the children whose mother smoked developed 20% more cold
and breathing diseases than other children later in life.
Another recent study found
that children had a greater chance of developing lung cancer if their mothers
smoked.
The study also showed that
the danger of lung cancer increased only for sons and not for daughters, and
that the father’s smoking did not affect a child’s chance of developing lung
cancer.
