Abstract

Introduction: The P300 is an objective procedure for assessment of hearing function. The elicitation of its components involves cortical areas related to perception, attention, auditory memory and cognition mechanisms. Objective: To evaluate the latencies of N1 , N2 , P1 , P2 and P3 in adolescents according to nutritional status and social, economic, demographic and educational variables Methods: A case series study was carried out involving 32 adolescents aged 13-18 years of both sexes attending public schools in Recife - PE. The P300 components were analyzed with 200 stimuli by using the Ep Smart Intelligent Hearing Systems (IHS) device. Results: It was observed that adolescents with records of class repetition had higher (p= 0.04) extension of P1 component latency when compared to adolescents without class repletion records, as well as adolescents from higher social-economic profile had better P3 component latency, when compared with those situated in lower socio-economic level. Conclusion: Prolongation in latency of P1 and P3 components were found in adolescents with class repetition records and lower socioeconomic status.
