Scientists have reported the first long-term study of children who were born earlier and smaller than normal. The
researchers measured the progress of these premature babies compared with normal children.

Maureen Hack² of Rainbow Babies and Children’s Hospital in Cleveland, Ohio led the
twenty-year study. The New England Journal of Medicine published the results.The
researchers studied almost five-hundred premature and normal children. The children were
born in a poor area of Cleveland between Nineteen-Seventy-Seven and Nineteen -Seventy-
Nine.

On average, the premature babies were born in the twenty-ninth week of pregnancy³. Thirty-
seven weeks of pregnancy is considered full-term. The babies weighed less than one-thousand-five -hundred
grams. They were more likely to have serious medical problems including cerebral⁴ palsy, blindness and lung
disease.

The premature group did worse on intelligence tests than the others. Still, seventy-four percent of them
completed high school. Eighty-three percent of the normal group finished high school.

Both groups tested lower than average on intelligence tests. Experts say these results may not represent the rest of
the nation. They say children from rich families usually do better on intelligence tests.

The researchers say the study showed that the young people born too soon got into less trouble than the other
group. They had fewer problems with alcohol, drugs and crime. The girls had fewer pregnancies⁵. Children of
lower intelligence often get involved in risk-taking activities. So the scientists had not expected this result.

Doctor Hack said the medical problems of the premature group did not surprise the researchers. The babies were
born before their organs had a chance to fully⁶ develop. Blindness and lung disease often threaten premature
babies. Some also suffer severe muscular damage.

The researchers say the premature children had unusually protective and careful parents. This may have saved
their lives. The researchers also say extremely watchful⁷ parents may have prevented the children from getting
into trouble.

About forty -thousand premature babies are born each year in the United States. This is about one -percent of the
total number of babies born in this country every year.
