Gestational age

Gestational age is the duration of pregnancy in completed weeks.


The first weight of the baby taken within an hour of birth.

Birthweight adjusted for gestational age

Allows for differentiation in a baby’s growth status and maturity to be taken into account.

Active measures taken shortly after birth to assist the baby’s ventilation and heartbeat or to treat depressed respiratory effort or correct metabolic disturbances.
