Language development of term and preterm children during the first five years of life.
Language development during the first five years is reported for 114 high-risk preterm children (20 with varying degrees of cerebral palsy) and 97 healthy term children. Most stages of language development occurred at slightly later ages among the neurologically unimpaired preterm children than among those born at term. Preterm children with cerebral palsy were more delayed and had more articulation defects compared with neurologically unimpaired preterm children. Girls were more advanced in early language development and showed less articulation defects than boys. The perinatal optimality score was significantly correlated with the ages at which the stages of language development were reached, and with language performance at five years in preterm children, but much less in term children. Birthweight and gestational age were negatively correlated with language development at all ages. Socio-economic status and birth order had an age-related influences on language development, but no correlation was found with the number of minor congenital malformations.
