BIRTH-WEIGHT AND GESTATIONAL-AGE IN CHILDREN WITH CEREBRAL-PALSY OR SEIZURE DISORDERS

Birth weight and gestational age of single-born children with cerebral palsy (CP) and those with seizure disorders were compared with norms for 40,000 single-born children in the same prospectively identified population. Low birth-weight and short gestation were important risk factors for CP, but these characteristics were uncommon, and the majority of children with CP were of normal birth weight and term gestational age. Preterm children with CP by age 7 years tended to have been even smaller at birth than was appropriate for their short gestations. Among term infants with later CP, the birth weights of the majority were appropriate for dates, but a subgroup were noticeably small for dates at term. Low birth weight, preterm birth, and smallness for dates at term were not significantly related to the risk of seizure disorders in children free of CP. © 1979, American Medical Association.
