OBJECTIVES: to describe the findings of the brainstem auditive evoked potential (BAEP) test in children on a neonatal auditive triage program and analyze the difference in gender and the interference of age on the measurement of BAEP interwave latency. METHODS: 41 children aged between one and nine months referred to a Municipal Triage Program of the Education and Health Study Centre (EHSS) in the town of Marília, São Paulo State, Brazil in the year of 2010 were evaluated. RESULTS: a normal result in 31 (75.6%) and an altered result in 10 (24.4%) patients were observed. Among the latter, alterations principally of the unilateral and bilateral conductive types were observed. It was also observed that with increasing age, the interwave latency decreased in an inverse correlation. CONCLUSIONS: the diagnosis of children in this Neonatal Auditive Triage Program was premature. The results of the BAEP can serve as a reference for other studies in this field. Applying BAEP in this population allows a better direction of conduct and intervention and specific counseling for family members.
