Prevalence Of Auditory And Vestibular Symptoms Among Workers Exposed To Occupational Noise [prevalência De Sintomas Auditivos E Vestibulares Em Trabalhadores Expostos A Ruído Ocupacional]

The purpose of the study was to assess the prevalence of auditory and vestibular symptoms in workers exposed to occupational noise. There were examined medical records of 175 workers with noise-induced hearing loss who attended an occupational health reference center in the city Campinas, Southeastern Brazil, from 1997 to 2003. The variables studied were frequency of symptoms of hypoacusis, tinnitus, and vertigo. Association with age, noise exposure time, and auditory thresholds were analyzed using the chi-square test and Fisher's exact test. Hypoacusis was reported in 74% of cases, tinnitus in 81%, and vertigo in 13.2%. There was found an association between hypoacusis and age, noise exposure time, and auditory thresholds and between vertigo and noise exposure time. No other significant associations were found. © 2009 Faculdade de Saúde Pública da Universidade de São Paulo.432377380Aragute, M., Souza, M.M.N., Mastrochirico, R.J., Santos, S.A., Caracterização do zumbido em trabalhadores atendidos no CERESTSP (2000) Disturb Comun, 11 (2), pp. 207-225Dias, A., Cordeiro, R., Corrente, J.E., Gonçalves, C.G.O., Associação entre perda auditiva induzida pelo ruído e zumbidos (2006) Cad Saude Publica, 22 (1), pp. 63-8. , DOI:10.1590/S0102-311X2006000100007Golz, A., Westerman, S.T., Westerman, L.M., Goldenberg, D., Netzer, A., Wiedmyer, T., The effects of noise on the vestibular system (2001) Am J Otolaryngol, 22 (3), pp. 190-6. , DOI:10.1053/ajot.2001.23428Neuberger, M., Korpert, K., Raber, A., Schwtz, F., Bauer, P., Hearing loss from industrial noise, head injury and ear disease - a multivariate analysis on audiometric examinations of 110647 workers (1992) Audiology, 31 (1), pp. 45-57. , DOI:10.3109/00206099209072901Nudelmann, A.A., Costa, E.A., Seligman, J., Ibañez, R.N., Atualização sobre os documentos do Comitê Nacional de Ruído e Conservação Auditiva (2001) PAIR - Perda auditiva induzida pelo ruído, pp. 225-34. , Nudelmann AA, Costa EA, Seligman J.
