One reason is that until the 1970s, the chances of survival for a baby born before the 37th week of pregnancy were very slim. The other is that it is difficult, sometimes difficult, to follow thousands of premature infants for several years, even into adulthood, in order to subject them to regular learning and behavior tests, with all the mystery this places on them and their parents. in 2015, Journal report nature He further emphasized how “we are just beginning to understand the effects of preterm birth”.
