title: Language development of very low birth weight infants and fullterm controls at 12 months of age.
abstract: Twenty-eight very low birth weight (VLBW) and 32 full term infants were prospectively assessed at one year of age for hearing, language development and neurological status. The prevalence of conductive hearing deficits was the same in both groups. Language scores in VLBW infants were significantly lower than in fullterm controls and 39% had significant language delays. VLBW infants exhibited a shorter attention span and were less likely to understand simple questions, to recognize objects or body parts when named, to initiate speech-gesture games, to follow simple commands and to imitate or use words consistently. Language quotients were directly associated with gestational age and five minute Apgar scores and inversely associated with severity of intraventricular hemorrhage, bronchopulmonary dysplasia and length of hospital stay. VLBW small for gestational age infants exhibited more advanced language skills than VLBW appropriate for gestational age infants. Language delays were more prevalent among, but not limited to, infants with mild to moderate neurological abnormalities. The influence of prematurity and VLBW on language development is complex and multifactorial and research is continuing to determine the predictive validity and long term significance of the early language delays described in this study.
