According to the most recent estimates, preterm birth is a leading cause of under-5 mortality, claiming nearly 1 million lives every year, with the rate of preterm birth increasing in many countries.
The World Health Organization defines preterm birth as babies born alive before 37 weeks of pregnancy are completed. While many preterm babies survive in high-income countries, in low- and middle-income countries a lack of adequate newborn care puts the lives of many preterm babies at risk.

Preventing preterm birth
Although we still do not have a full understanding of the causes of preterm birth, several interventions may reduce the risk of a woman delivering early, including high-quality antenatal care; good nutrition; screening and management of maternal infections, diabetes, and hypertension; smoking cessation; family planning; and prenatal care for adolescents. If a woman presents in preterm labor, administration of antenatal corticosteroids may reduce mortality from respiratory distress, and antibiotics can reduce a baby’s risk for infection.
