What term is used for babies born before the 37th week of pregnancy?

The correct term for babies born before the 37th week of pregnancy is "Preterm." This classification indicates that the baby was delivered before reaching the full term, which is typically 39 to 40 weeks. Babies who are preterm may face various health challenges due to being born too early, as they might not have developed fully, particularly in terms of their lungs and other vital organs.

While "Premature" often describes the same situation and is used interchangeably with "Preterm," in the context of the question, "Preterm" is the specific term recognized in medical definitions to designate the gestational age of the baby accurately. This understanding helps in assessing the risks involved for preterm infants and the appropriate medical interventions they may require immediately after birth.
