2002 Cohort
Extremely low birth weight infants (401-1000 g) born during 2002 and who survived discharge home were tracked and evaluated between 18 and 24 months corrected age at participating Network Centers. Twenty-seven Centers actively participated in this year's project. One thousand two hundred and thirty-five infants survived and were eligible for follow-up. Of those infants, 744 received health and neurodevelopmental status evaluations. Twenty nine percent of these evaluated infants were severely growth retarded (< 3rd percentile body size) and 10% had microcephaly (< 3rd percentile head size). Thirty eght percent of the infants were rehospitalized and 28% required rehospitalization for a surgical procedure. Overall, 27% had severe disability defined as having one of the following: bilateral blindness (.2%), hearing impairment requiring amplification (2%), inability to walk with support (3.8%), cerebral palsy (7.3%), or Bayley mental development index score < 70 (21.9%).

1998-2002 Cohort

Extremely low birth weight infants (401-1000 g) born between 1998-2002 who survived discharge home are being tracked and evaluated between 18 and 24 months corrected age at participating Network Centers. Twenty-four centers actively participated. Data completed for the 2002 Cohort year was combined with data for the completed 1998, 1999, 2000 and 2001 cohorts and analyzed as a five year cohort. Five thousand four hundred and fifty three infants survived and were eligible for follow-up. Of those infants, 3190 received health and neurodevelopmental status evaluations. One third of these evaluated infants were severely growth retarded (< 3rd percentile body size) and 12% had microcephaly (< 3rd percentile head size). Thirty percent of the infants were rehospitalized and 31% required rehospitalization for a surgical procedure. Overall, 30% had severe disability defined as having one of the following: bilateral blindness (1.1%), hearing impairment requiring amplification (2%), inability to walk with support (4.2%), cerebral palsy (8.3%), or Bayley mental development index score < 70 (23.5%).
