Abstract
Objective
To assess the prevalence and predictors of language and visuomotor delay in very low birthweight (≤1250 g) children at corrected age (CA) of 2 years.
Design
Prospective observational.
Setting
Neonatal follow-up clinic of a level III center.
Participants
Children with birthweight ≤1250 g and discharged alive (n=164) from April 2012 to April 2013 were followed up till 2 years CA (n=126).
Methods
Development, neurological status, and language/visuomotor cognitive skills were assessed by Cognitive Adaptive Test/Clinical Linguistic and Auditory Milestone Scale (CAT/CLAMS). Development Quotient (DQ) was calculated.
Main Outcome
Prevalence and predictors for the language and visuomotor delay.
Results
At 2 years (n=123 CAT, 126 CLAMS), 30 (24%) children had below average DQ (90) and 93 (74%) average and above average DQ (≥90) in full scale CAT/CLAMS test. Small for gestation infants (n=86) have higher risk of below average DQ (P=0.036). Gestational age and socioeconomic status have a positive correlation with language development at 9 months and 2 years, respectively.
Conclusions
In VLBW (birth weight ≤1250 g) infants, the prevalence of language/visuomotor delay is high. Small for gestational age infants are at higher risk for language and visuomotor development delay at 2 years corrected age.
