Anomalies in the definitions

Authoring team

There are many discrepancies in the definitions used for classifying perinatal mortality:

  • gestational age may be uncertain with stillbirths

  • the time of delivery of a stillbirth is often not the time of death

  • stillbirth is deemed to be from 24 weeks only, however live birth can occur as early as 23 weeks; 23 week gestation babies who show signs of life and subsequently die are early neonatal deaths; the same baby who is not alive when born is not included in the tally.

  • there is a grey area between livebirth and abortion at very early gestational ages
