Understanding Corrected Age

Corrected age (also called adjusted age) is used for premature babies to account for their early arrival. It represents the age the child would be if born at full term (40 weeks gestation).

How is it calculated?

Corrected Age = Chronological Age - (40 weeks - Gestational Age at Birth)

For example, a baby born at 32 weeks who is now 4 months old chronologically would have a corrected age of 2 months (4 months - 2 months early = 2 months corrected).

Why is corrected age important?

  • Developmental milestones should be assessed using corrected age
  • Growth charts are more accurate when using corrected age
  • Vaccination schedules may be adjusted based on corrected age
  • It helps set realistic expectations for development

When to stop using corrected age?

Most healthcare providers recommend using corrected age until the child is 2-3 years old, as the developmental gap typically closes by this time. However, this varies based on the degree of prematurity and individual development.

Important: Always consult with your pediatrician for medical advice regarding your premature infant\'s development and care.
