Each year in the U.S., more than 440,000 babies are born too soon (preterm). Many of these are premature infants, born before the end of 37 weeks of pregnancy, also are dangerously small, weighing less than 5 1/2 pounds. Compared with a full-term baby, one born too soon has a much greater chance of dying, having breathing problems, or suffering lifelong medical complications such as cerebral palsy, visual and hearing disabilities, and mental retardation. About 75% of infant deaths in the first month of life occur in preterm infants.

Although vast improvements have been made in treating premature infants, thus far there has been little success in understanding and preventing prematurity. In fact, since the early 1980s, the rate of preterm birth has actually increased by 17% and the rate of low birthweight has risen 10 percent. For reasons we don't fully understand, these problems take a disproportionate toll on African Americans.

There are still major gaps in our understanding of why some women go into labor well ahead of schedule. Cigarette smoking, disorders that raise blood pressure, prior preterm birth and certain pregnancy complications make a well-recognized contribution to the risk of prematurity, but they account for only a small amount of the problem. Recent research suggest that some environmental factors (e.g. genital tract infection, stress, anxiety, depression) also may play important, but as yet unspecified, roles in determining a woman's risk of delivering a preterm baby. This workshop built on previous research, and focused on the role of environmental toxins, an area often overlooked, as a risk factor for delivering a preterm infant.
