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.
Depending on how early a baby is born, he or she may be: 1  Late preterm, born between 34 and 36 weeks of pregnancy. 2  Moderately preterm, born between 32 and 34 weeks of pregnancy. 3  Very preterm, born at less than 32 weeks of pregnancy.  Extremely preterm, born at or before 25 weeks of pregnancy.
