1998 Cohort

Results

Extremely low birth weight infants (401-1000 g) born during the last six months of 1998 and who survived discharge home were tracked and evaluated between 18 and 24 months corrected age at participating Network Centers.  Five hundred-sixty five infants survived and were eligible for follow-up. Of those infants, 327 received health and neurodevelopmental status evaluations. One third of these infants were severely growth retarded (<3rd percentile body size) and 13% had microcephaly (<3rd percentile head size). Nearly half of the infants were rehospitalized and 33% required surgical procedures. Overall, 35% had severe disability defined as having one of the following: bilateral blindness (1.2%), hearing impairment requiring amplification (4.2%), inability to walk with support (3.0%), cerebral palsy (11.3%), or Bayley mental development index score < 70 (27.9%).
