2001 Cohort
Extremely low birth weight infants (401-1000 g) born during 2001 and who survived
discharge home were tracked and evaluated between 18 and 24 months corrected
age at participating Network Centers. Twenty-six Centers actively participated in this year's project. One thousand one hundred and seventy-seven infants survived and were eligible for follow-up. Of those infants, 671 received health and
neurodevelopmental status evaluations.
Thirty four percent of these evaluated infants were severely growth retarded
(< 3rd percentile body size) and 14% had microcephaly (< 3rd percentile head size).
Thirty nine percent of the infants were rehospitalized and 31% required rehospitalization
for a surgical procedure. Overall, 31% had severe disability defined as having one of
the following: bilateral blindness (1.6%), hearing impairment requiring
amplification (1.5%), inability to walk with support (3.8%), cerebral palsy (7.1%),
or Bayley mental development index score < 70 (25.7%).
1998-2001 Cohort
Extremely low birth weight infants (401-1000 g) born between 1998-2001
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 2001
Cohort year was combined with data for the completed 1998, 1999 and 2000 cohorts
and analyzed as a four year cohort. Four thousand two hundred eighteen infants
survived and were eligible for follow-up. Of those infants, 2446 received
health and neurodevelopmental status evaluations. One third of these evaluated
infants were severely growth retarded (< 3rd percentile body size)
and 13% had microcephaly (< 3rd percentile head size). Forty two percent of the infants were rehospitalized and 32% required rehospitalization
for a surgical procedure. Overall, 31% had severe disability defined as
having one of the following: bilateral blindness (1.4%), hearing impairment
requiring amplification (2%), inability to walk with support (4.2%),
cerebral palsy (8.6%), or Bayley mental development index score < 70
(24.2%).
