School performance of children with birth weights of 1,000 g or less
Insights
Neonatal intensive care survivors born weighing 1,000g or less often experience significant neurodevelopmental challenges. These children frequently require special education and exhibit specific academic and motor skill deficits.
Area of Science:
- Neonatalogy
- Developmental Pediatrics
- Neuroscience
Background:
- Long-term outcomes for extremely low birth weight infants remain a critical area of research.
- Understanding the neurodevelopmental trajectory of survivors born weighing 1,000 grams or less is essential for early intervention.
Purpose of the Study:
- To assess the neurodevelopmental status and academic achievement of long-term survivors born with birth weights of 1,000 grams or less.
- To identify specific areas of cognitive and motor impairment in this high-risk population.
Main Methods:
- Retrospective examination of 25 survivors from a neonatal intensive care unit cohort (1960-1972).
- Assessment included evaluation of neurologic and sensory handicaps, special education placement, academic performance, and motor skills at a mean age of 10.6 years.
Main Results:
- 28% of survivors had major neurologic or sensory handicaps.
- 64% required special education services.
- Only 28% achieved at or above grade level, with specific weaknesses in arithmetic reasoning, mathematics achievement, and reading comprehension.
- Impairments in fine and gross motor skills were noted, with lesser impairment in perceptual skills.
Conclusions:
- Extremely low birth weight infants surviving neonatal intensive care face significant long-term neurodevelopmental challenges.
- Early identification and targeted interventions are crucial for supporting academic and motor skill development in these children.
- Continued follow-up is necessary to optimize outcomes for survivors of neonatal intensive care.
Abstract:
Twenty-five of the 45 long-term survivors with birth weights of 1,000 g or less who were cared for in the University of Washington, Seattle, Neonatal Intensive Care Unit from 1960 to 1972 were examined at a mean age of 10.6 years. Seven of the 25 children (28%) had one or more major neurologic or sensory handicaps. Sixteen (64%) have been or presently are in a special education program. Only seven children (28%) are currently rated by their teachers to be achieving at or above grade level. Arithmetic reasoning, mathematics achievement, and reading comprehension were specific weaknesses. Fine and gross motor skills were impaired. Perceptual skills were impaired to a lesser degree.
