What is the preterm birth rate among twin gestations in the US?

The preterm birth rate among twin gestations in the United States is around 59%. This high rate of preterm birth is primarily attributed to the increased risk factors associated with multiple gestations, including uterine distension, higher rates of infections, and potential complications such as preeclampsia. Twins, due to their shared resources and space, often trigger physiological changes and complications that can lead to earlier birth compared to singleton pregnancies. It is essential for healthcare providers to monitor twin pregnancies closely because the risks associated with prematurity for the infants can include respiratory issues, developmental delays, and other health concerns. The significant proportion of twin pregnancies resulting in preterm birth highlights the necessity for proactive prenatal care and intervention strategies to improve outcomes for both mothers and their babies.
