Indicator Profile of Preterm Singleton Births

Why Is This Important?

Prematurity increases the risk for infant morbidity and mortality. Infants born preterm are at greater risk of dying in the first month of life. Preterm infants may require intensive care at birth and are at higher risk of developmental disabilities and chronic illnesses throughout life. They are more likely to require special education services. Health care costs and length of hospital stay are higher for preterm infants.

There are many health, behavioral, and environmental factors known to increase the risk of preterm birth. Therefore, it is useful to track preterm birth as part of an Environmental Public Health Tracking system.
