Slide: 3 of 29

The Burden of Preterm Birth

Preterm birth is defined as birth prior to the 37th week of pregnancy. Each year in the United States, 12.5 percent of births (representing more than 475,000 infants) occur preterm.

The risk of complications from preterm birth is related to how early the birth occurs. The morbidity and mortality associated with preterm birth represent untold distress for families, as well as significant costs to patients, health care systems, and payers. The estimated additional cost for neonatal care is $17,300 (2004 dollars) per preterm infant.
