This is the VOA Special English Science Report.

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 Hack 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 pregnancy. 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 cerebral 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 pregnancies. 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 fully 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 watchful 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.

That's odd because people have said some of the world's greatest minds were born premature.

Really?? <,< Like who, if you know any off the top of your head?

Hmm. It's like one of those things people just say in passing. So, it's not like fact.

I went to a really gifted high school and some of the people I knew told me they were born premature.

I also think some Nobel Laureates were born premature.

But I think the genuius-ness and prematurity thing are just coincidences. Prematureness usually (should) does more harm.

Yeah... underdevelopment. Very fragile at premature stage.

Albert Einstein's mother was told that he would never be able to accomplish things that normal humans do, and look what he accomplished.

I wonder if this has anything to do with the age of the mothers. Because there are a lot more older women having babies now, and some of them are being aided by science. Or maybe it has to do with how young the mothers are, like teen pregnancy.

Biological clock definitely has a role. If you're too young, your uterus and body hasn't completely developed to handle child bearing. If you're too old, your body just isn't up for child bearing either.

hmm i found this really interesting. i guess i kinda fall into this because i was born 3 months early, 2 pounds 2 ounces. i'm healthy.. but i struggle in school =T
