American doctors say that mothers smoke before their
21
babies are born may slow the growth of their babies
22
lungs. They say reducing lung growth could cause
23
the babies suffer breathing problems and lung disease
24
late in life. Doctors in Boston studied 1,100 children.
25
The mothers of some of the children smoked; the other
26
Mothers did not. Doctor found out that the lungs of the
27
children whose mothers smoked were 8% less developed as
28
the children whose mothers did not smoke, that the
29
children whose mothers smoked were developed 20% more
30
cold and breathing diseases than the other children.
