March of Dimes commits additional $2.4 million to prematurity research

In its ongoing effort to predict and prevent premature birth, the March of Dimes will support the innovative research of six scientists with combined grants of more than $2.4 million.

The second annual Prematurity Research Initiative (PRI) grants were awarded to four U.S.-based scientists, two from Connecticut, one each from California and Louisiana, and two working in other countries. The grants are awarded to the scientists for a three year period.

Several of the studies seek to find new ways to identify women who are at increased risk for premature birth by studying their genetic patterns.

Three of the research projects focus on what role a woman's inflammatory response to infection may play in triggering labor. By moderating or suppressing genes that control inflammatory response, it may be possible to prevent more premature births, which are the leading cause of newborn death in the United States.

Two projects focus on the role of the hormone progesterone in delaying early labor. Earlier studies have shown that giving women with a singleton pregnancy, who have had a previous spontaneous preterm delivery, weekly injections of progesterone can significantly reduce their risk of having a subsequent premature baby. Understanding of how the uterus responds to progesterone could allow doctors to better predict and prevent early labor.

More than a half million babies are born too soon each year and the preterm birth rate has increased 30 percent since 1981, the first year the government began tracking premature birth rates. While there are several factors that can help predict the risk of preterm birth, there is no known cause for half the cases of premature birth.

"These grants show the March of Dimes increasing investment in research to discover the causes of preterm labor," said Jennifer L. Howse, president of the March of Dimes. "The number of premature births is now more than 500,000 annually and the l
