PURPOSE: To compare language development, according to gender, gestational age and birth weight, at four, eight and 12 months of life, of infants who remained in the Neonate Intensive Care Unit, who presented at least one risk factor for hearing loss with delayed onset. METHODS: Longitudinal study of infants born between August 2007 and July 2008, who, in the Intensive Care Unit (ICU), showed normal results in the Automated Auditory Brainstem Evoked Potential test, and required audiological and language monitoring for presenting risk factors for hearing loss. The infants were assessed at four, eight and 12 months, using the Early Language Milestone Scale. RESULTS: Eighty-seven infants were evaluated, and 60 (69%) of them presented, as a risk factor, the permanence at the ICU associated with pulmonary hypertension. In the Early Language Milestone Scale, nine infants showed alterations at four months, and 11 at eight months of age. At 12 months, 18 (20.6%) infants showed alterations, and five of these had showed delays in the previous evaluations. Statistical analyses demonstrated that altered results at four and eight months can predict difficulties in the infant's responses at 12 months. The infants showed transitory alterations in oral language development, which were overcome in most cases. CONCLUSION: The first language evaluation of children with risk factors for hearing loss should be carried during the first year of life, allowing early detection of language development issues.
