What is Known:
• Fetal, neonatal, or postnatal charts have been considered to monitor the postnatal growth of preterm infants.
• This selection influences the diagnosis of “extrauterine growth restriction” (EUGR) and the clinical strategies used.
What is New:
• Extrauterine growth restriction (EUGR) in small-for-gestational-age (SGA) infants can not be considered a true EUGR but a postnatal evolution of fetal growth restriction.
• Preeclampsia, low gestational age, severe neonatal morbidity and male sex are independently associated with EUGR in non-SGA infants (named “true-EUGR”), which can be expected in 15% of very preterm infants by 2-2.5 years of age.
