Zusammenfassung:► Different longitudinal gestural and linguistic trajectories in preterms and full-terms. ► Slower rate of development and increasing divergence between preterms and full-terms. ► Lexical comprehension and gestures/actions support development of lexical production. ► Biological, medical and social risk factors increase preterms’ risk of language delay. 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 (
