Neurodevelopmental and behavioral outcome of very low birth weight babies at corrected age of 2 years.
OBJECTIVE
Neurodevelopmental and behavioral assessment of very low birth weight babies (VLBW) at corrected age (CA) of 2 years.


METHODS
127, 110, 99 and 101 babies ≤34 weeks and ≤1500 g were followed at CA of 3, 6, 9, 12 months respectively for developmental and neurological assessment. DASII (Developmental assessment scale for Indian infants) was used at CA of 18 months and preschool behavioural checklist (PBCL) at CA 2 years.


RESULTS
Of 101 VLBW babies available for follow up at CA 1 year, 3 (3%) babies had Cerebral Palsy (CP) and 3% (n = 3) had suspect abnormality (mild hypotonia), 11% (n = 11) had gross motor and 8% (n = 8) had language abnormality. Their mean mental (MeDQ) and motor (MoDQ) quotients were 80.4 ± 10.7 and 77.2 ± 13.3 and a score of < 70 was found in 17% (MeDQ) and 25.7% (MoDQ) VLBW babies. High PBCL score (mean 16.8 ± 5.4) was seen in 84%VLBW babies. On subgroup analysis, 2 babies (5%) in subgroup1 ( n = 54, ≤1200 g,) and 1 (1.6%) in subgroup 2 (n = 78, 1201-1500 g) had CP. Twelve (29%) in subgroup 1 had significant language delay (p = 0.004) as compared to 4 (15%) in subgroup 2 at 1 year. BSID and PBCL scores were comparable. Amongst ELBW babies (<1000 g), 6.6% (n = 1) had CP, 25% (n = 3) and 42% (n = 5) had low MeDQ and MoDQ respectively and all of them had high PBCL score. AGA and SGA had similar outcome.


CONCLUSIONS
VLBW babies need close and longer follow up due to high risk of neurodevelopmental and behavioral abnormality.
