adjusted age

A premature infant's chronological age minus the number of weeks born before 40 weeks gestation, used to assess development appropriately.

Full Definition

Adjusted age, also called corrected age, accounts for prematurity when evaluating a child's development. It is calculated by subtracting the number of weeks a baby was born early from their current chronological age. This adjustment is typically used until age 2-3 years to provide a more accurate assessment of developmental progress. For example, a 6-month-old baby born 8 weeks premature would have an adjusted age of 4 months. Medical professionals use adjusted age when interpreting developmental screenings and milestones.

Usage

Usage note: Always specify which age reference is being used in developmental assessments.
