About Preterm Birth

According to the March of Dimes, preterm birth, or the birth of a baby prior to 37 completed weeks of pregnancy, affects one in eight babies born in the United States1. Additionally, the rate of preterm birth has increased more than 35 percent in the last 25 years2, and is the leading cause for infant mortality and morbidity. Preterm birth is currently the number one cause of neonatal mortality, and babies born preterm tend to grow more slowly, have more problems with their eyes, ears, breathing and nervous system, and experience more learning and behavioral problems3,4. Preterm birth has been estimated to cost the United States more than $26 billion a year5.
