Hipertensão como fator associado à perda auditiva

OBJETIVO: Identificar possivel associacao entre hipertensao arterial e perda auditiva. Foi realizado um estudo do tipo caso-controle nao pareado, na Universidade Norte do Parana, no Sul do Brasil. MATERIAL E METODO: 154 casos e 154 controles, de ambos os sexos com idade variando de 45 a 64 anos foram incluidos na pesquisa apos o calculo da amostra. A hipertensao foi verificada por medicao da pressao arterial e de questionario sistematizado sobre hipertensao e uso de medicamentos para pressao arterial. A audicao foi avaliada por audiometria e anamnese audiologica. A tecnica de regressao logistica nao-condicional foi utilizada com o objetivo de controlar a possivel acao de confusao ou modificacao de efeito exercida por outras variaveis sobre as associacoes de interesse. RESULTADOS : Pode-se verificar que existe associacao significativa entre hipertensao arterial e presenca de perda auditiva e que a perda auditiva observada nesta populacao sugere que a hipertensao arterial age como fator de aceleracao da degeneracao do aparelho auditivo proveniente da idade. CONCLUSOES: Os resultados da presente pesquisa, atraves da constatacao da associacao entre hipertensao e perda auditiva, servirao de base a uma integracao entre cardiologistas, nefrologistas, otorrinolaringologistas, fonoaudiologos e outros profissionais da area de com alteracoes provenientes da hipertensao.
