Every year an estimated 15 million babies are born preterm and this number is rising.
Preterm is defined as babies born alive before 37 weeks of pregnancy are completed.
There are sub-categories of preterm birth, based on gestational age: extremely preterm (less than 28 weeks), very preterm (28 to 32 weeks) and moderate to late preterm (32 to 37 weeks).
Induction or caesarean birth should not be planned before 39 completed weeks unless medically indicated.
According to World Health Organization (WHO), preterm birth complications are the leading cause of death among children under 5 years of age, responsible for approximately 1 million deaths in 2015.
