Clinical guideline reports obstetric and neonatal growth chart variations in newborns, highlighting the need to distinguish descriptive from prescriptive references.
The use of different growth charts can lead to confusion in discussions between professionals. There are obstetric charts (of fetal growth) and neonatal charts (of measurements at birth and of postnatal growth). These charts can be descriptive (derived from an unselected population) or prescriptive (derived from of a population at low risk and with optimal conditions for growth).
