Abstract The speech and language abilities of preterm and low birthweight children were studied at the age of 8 in the northern Finland 1-year birth cohort for 1985–86. The language abilities of 42 8-year-old preterm children with birthweight < 1750 g were studied with four different language tests: the Illinois Test of Psycholinguistic Abilities (ITPA), the Token Test for Children (TTC), the Morphological Test for Finnish speaking children (MT) and the Peabody Picture Vocabulary Test (PPVT). Full-term control children with birthweight ≥ 2500 g (n = 42) from the same birth cohort matched individually with their preterm pairs for age, sex, twinship, mother’s education, place of residence, birth order and family type were also studied. In addition, linguistic and motor abilities of low birthweight (LBW, < 2500 g) 8-year-old children (n = 279) were studied using parental (n = 8370, 90 %) and teacher (n = 8525, 92 %) evaluations by mailed questionnaire. The results showed that the 8-year-old preterm (< 1750 g) children scored significantly poorer than their controls in visual subtests measured by ITPA and that the poor performance in visual tests was associated with neonatal infections, continuous positive airway pressure (CPAP) and patent ductus arteriosus (PDA). In addition, the preterm children with minor neurodevelopmental dysfunction (MND) scored worst and differed significantly from their matched controls in verbal comprehension measured by TTC. They also differed significantly from other preterm groups, namely healthy preterm and preterm children with cerebral palsy (CP) in TTC. Periventricular leukomalasia (PVL) findings in magnetic resonance imaging (MRI) were not associated with the performance in the language ability tests. The parents evaluated the LBW (< 2500 g) children to have more problems in speech and language than the normal birth-weight (NBW, ≥ 2500 g) children. The LBW boys were the poorest in linguistic and motor skills compared with the NBW boys or any of the groups of girls. There ...
