Important growth and development occur throughout pregnancyâincluding in the final months and weeks. Premature (also known as preterm) birth is when a baby is born too early, before 37 weeks of pregnancy have been completed. The earlier a baby is born, the higher the risk of death or serious disability. In 2013, about one-third (36%) of infant deaths were due to preterm-related causes.
Birth is considered premature, or preterm, when it occurs before 37 weeks of gestation (development time in the womb). Normal, full-term gestation is 37 to 42 weeks. Those final weeks in the womb are crucial for healthy weight gain and development of the babyâs vital organs. Late preterm babies (born at 35 to 37 weeks gestation) may look fully mature, but they still have greater risks of health problems than babies born full term.
