What is corrected age in premature infants?

By Marta Barranquero Gómez B.Sc., M.Sc. (embryologist).
Last Update: 12/16/2022

The corrected age is the time the baby would have had if delivery had occurred at 40 weeks gestation. This age is recommended when you want to evaluate the physical and psychomotor development of the baby.

It is calculated by subtracting the weeks of prematurity from the baby's weeks since birth. For example, if the birth occurs in the 32nd week of pregnancy, the baby would be 8 weeks, that is, 2 months premature. If the baby is now 4 months old (16 weeks), the corrected age would be 4 minus 2 months.
