The concept of adjusting for prematurity helps compare an infant's development to milestones of which reference point?

• A. Term age milestones.
• B. Chronological age milestones.
• C. Adult milestones.
• D. Neonatal growth charts.

Answer: (A)

Adjusting for prematurity means evaluating a preterm infant against the milestones expected at full-term gestation, not against the child’s actual chronological age. Since the baby was born early, their brain and body have had less time to develop in utero, so using term age as a reference helps reflect where they should be developmentally at a given point in time. This is done by calculating an adjusted age (chronological age minus weeks of prematurity) and then comparing development to term-age milestones. For example, a baby born at 32 weeks who is 12 weeks old chronologically would have an adjusted age of about 4 weeks, so their development is judged against what a typical 1-month-old at term would be doing. The other options don’t fit because chronological age milestones don’t account for prematurity, adult milestones aren’t relevant, and neonatal growth charts track size rather than developmental milestones.
