Abstract

Abstract

The aim of the study was to estimate the prevalence of the exposure to ototraumatic factors and auditory symptoms, and to analyse the relations between these factors in a group of young healthy men. A total of 839 men, 19–22 years old, were recruited for the study when reporting for primary military service. A questionnaire was distributed and audiometry was performed. The prevalence of tinnitus, sensitivity to noise, and measured hearing impairment in the study group was 23.2%, 15.5%, and 14.5% respectively. Exposure to occupational noise often was reported by 21.4%, and playing loud music often by 16.5%. The young men who had experienced tinnitus after noise exposure had an elevated risk of high frequency hearing impairment, tinnitus, and sensitivity to noise. Those who played loud music had elevated prevalence values of tinnitus but not of hearing impairment. In this young group we observed high prevalence values of ototraumatic factors and auditory symptoms. We also observed significant correlations between tinnitus after noise exposure, self-assessed hearing symptoms, and hearing impairment.

Sumario

El objetivo de este estudio fue estimar la prevalencia de la exposición de factores traumáticos al oído y síntomas auditivos y analizar las relaciones entre estos factores y un grupo de hombres jóvenes y sanos. Un total de 839 hombres entre 19 y 22 años fueron reclutados para el estudio al momento que se reportaban para el servicio militar primario. Se distribuyó un cuestionario y se realizó una audiometría. En el grupo de estudio hubo presencia de acufeno, sensibilidad al ruido y se midió hipoacusia en un 23.2%, 15.5% y 14.5% respectivamente. EL 21.4% reportó exposición frecuente a ruido y 16.5% tocaban música a alta intensidad. El joven que presentó acufeno después de haberse expuesto a ruido tenía un alto riesgo de hipoacusia en frecuencias agudas, acufeno y sensibilidad al ruido. Aquellos que tocaban música a alta intensidad tenían valores de prevalencia elevados para acufeno pero no para hipoacusia. En este grupo de jóvenes observamos altos valores de prevalencia para factores traumáticos para el oído y síntomas auditivos. También observamos correlaciones significativas entre acufeno y exposición a ruido, síntomas auto-evaluados e hipoacusia.
