To get the gestation-adjusted age, we need to subtract the number of weeks the infant was born preterm from 40 weeks (full-term gestation) and add it to the chronological age.

40 weeks - 32 weeks (preterm) = 8 weeks

9 months = 36 weeks

36 weeks + 8 weeks (adjustment) = 44 weeks

44 weeks ÷ 4 weeks/month = 11 months

However, since the infant was born preterm, we need to subtract 2 months from the chronological age to get the gestational-adjusted age.

11 months - 2 months = 9 months

So the gestational-adjusted age for a 9-month-old infant born preterm (32 weeks) is 7 months.
