Percentage of VLBW infants born AGA or SGA (less than −2 SD26) with subnormal (less than −2 SD30) weight or height for age at birth, 40 weeks, 8 months, 20 months, and 8 years corrected age and at 20 years postnatal age.
↵¶ 99 male and 87 female VLBW and all the NBW subjects had weight and height measurements at age 8 years.
↵†† For males, mean age at the 8-year assessment was 8.7 years for VLBW and 8.9 years for NBW subjects. For females, mean age at the 8-year assessment was 8.6 years for VLBW and 9.0 years for NBW subjects.
↵§§ For males, mean age at the 20-year assessment was 20.2 years for VLBW and 20.1 years for NBW subjects. For females, mean age at the 20-year assessment was 20.1 years for VLBW and 20.1 years for NBW subjects.
