title: Preschool performance of children with normal intelligence who were very low-birth-weight infants.
abstract: Children who were very low-birth-weight infants (less than 1,500 g), beneficiaries of modern neonatal intensive care, are now of school age. To evaluate their school performance 80 children born in 1976 who had very low-birth-weight (mean birth weight 1.2 kg, mean gestational age 30 weeks) were examined at age 5 years. Sixty-five children were neurologically intact and had normal IQ (greater than or equal to 85) on the Stanford-Binet; five children were neurologically abnormal and ten had IQ below 85. Of the 65 children with normal intelligence and no neurologic impairments, 46 were single births and enrolled in preschool. These 46 children were matched by race, sex, and family background with classmate control children who had been born at full term. Outcome measurements included the Slosson Intelligence Test, the Woodcock-Johnson Psycho-Educational Battery (including subscales of Picture Vocabulary, Spatial Relations, Memory for Sentences, Visual Auditory Learning, Quantitative Concepts, and Blending) and the Beery Developmental Test of Visual-Motor Integration. No significant differences in IQ were found between children who were very low-birth-weight infants and control children; however, children who were very low-birth-weight infants performed significantly less well on the Spatial Relations subtest of the Woodcock-Johnson and on the Visual-Motor Integration test. Similar results were found for nine sets of twins and their control children. Recognition of these perceptual and visual-motor problems may permit appropriate early remedial intervention and prevent the compounding of these difficulties.
