Adjusted age is used to estimate appropriate developmental expectations based on what calculation?

• A. Subtracting weeks premature from chronological age.
• B. Adding weeks premature to chronological age.
• C. Subtracting chronological age from weeks premature.
• D. Multiplying weeks prematurity by chronological age.

Answer: (A)

Adjusted age accounts for prematurity by subtracting the number of weeks the infant was premature from their chronological age (time since birth). This calculation aligns developmental expectations with what a full-term infant would achieve, helping clinicians assess milestones appropriately for preterm children. For example, a baby born 8 weeks early who is now 12 weeks old has an adjusted age of 4 weeks. This approach is used to compare development to term peers, especially in the first two years when the adjustment is most relevant. The other options don’t fit: adding weeks premature would overestimate age, subtracting chronological age from weeks premature would yield a meaningless negative value, and multiplying weeks prematurity by chronological age isn’t a valid way to gauge development.
