The present study involved a systematic longitudinal analysis, with three points of assessment in the second year of life, of gestures/actions, word comprehension, and word production in a sample of very preterm infants compared to a sample of full-term infants. The relationships among these competencies as well as their predictive value on language development at 24 months and the contribution of biological, medical and social risk factors on language delay at 24 months were also analysed. One hundred and four monolingual Italian very preterms (mean gestational age 29.5 weeks) without major cerebral damages, and a comparison group of 20 monolingual healthy Italian full-terms were followed at 12, 18 and 24 months by administering to their parents the Italian short forms of the MacArthur-Bates CDI. Preterms showed a slower acquisition in gesture/action production, word comprehension, and word production with an increasing divergence with respect to full-terms from 12 to 24 months, when 20% of preterms were delayed in word production (less than 10th percentile) and 14% did not combine words yet. Lexical competencies at 12 months and together with gestures/actions at 18 months were predictive of word production at 24 months, with a stronger contribution of word comprehension at 12 months and of word production at 18 months. Male gender, bronchopulmonary dysplasia, and low maternal educational level increased the risk of language delay at 24 months. Our findings suggest there to be a slower rate of communicative-linguistic development in very preterms with an increasing difference in their gestural and lexical competencies in the second year of life with respect to full-terms. The interplay of the above competencies and biological, medical and social risk factors increase the risk of language delay at 24 months in very preterm infants. (Contains 6 tables and 3 figures.)
