The March of Dimes has announced a major fund raising effort to understand and battle premature deliveries.
March of Dimes medical director Dr. Nancy Green told Time magazine that there has been a 27 percent rise in premature births over the last few decades. (http://www.time.com/time/magazine/article/0,9171,1101030210-418559,00.html)
At least 50 published studies have shown significantly higher risk of premature birth and low birth weight deliveries among women with a history of abortion.(1-50)
One of the best, a Danish record based study (1), found the risk doubled after just one abortion. Multiple abortions increase the risk even more. A doubling of risk among an estimated one-fourth of delivering women who have a prior history of abortion would result in a 25 percent rise overall. Other risk factors such as drinking, smoking, and drug use are also elevated by a history of abortion. According to the March of Dimes, "In 2000, hospital charges for 23,000 prematurity-related infant stays totaled $1.2 billion. The average charge was $58,000 per baby, compared to $4,300 for a typical newborn stay." (http://www.marchofdimes.com/aboutus/791_6775.asp) Treatment of these children through employer health plans is estimated at $4.7 billion per year. One fifth of these costs may be is attributable to extra cases of prematurity arising from abortion-related morbidity.

Premature birth is the leading cause of neonatal death and is related to increased risk of cerebral palsy, vision and hearing loss, retardation and other lifelong health problems.
The March of Dimes encourages prenatal screening for birth defects that can only be "treated" by abortion yet claims that they are neutral.
