Prevalência de zumbido, em idosos com e sem história de exposição ao ruído ocupacional / Prevalence of tinnitus in elderly individuals with and without history of occupational noise exposure

Introdução: A variedade de alterações metabólicas e circulatórias relacionadas com o ruído pode causar o aparecimento de inúmeros sintomas auditivos, incluindo, zumbido. Objetivo: O objetivo do estudo foi avaliar a prevalência de queixa de zumbido, em idosos com e sem história de exposição ao ruído ocupacional. Método: Forma de estudo prospectivo foi realizado em uma amostra populacional com 502 indivíduos com idade superior a 60 anos, através de questionário padronizado e avaliação audiológica. As variáveis estudadas foram frequência de queixa de zumbido e de e história de ruído ocupacional. Foi usada regressão logística para controlar confusão ou modificação de efeito para as outras variáveis sobre as associações de interesse. Resultado e Discussão: A queixa de zumbido foi verificada em 50% dos idosos com história de exposição ao ruído ocupacional e em 40,43% dos idosos sem história de exposição ao ruído ocupacional. Uma alta frequência de queixa de zumbido foi detectada na população sob investigação, porém não houve significativa diferença estatística entre a queixa de zumbido e história de ruído ocupacional. Conclusão: O resultado desta pesquisa pode ter ocorrido devido à existência de outros fatores que podem ter contribuído para a presença de zumbido, como a própria idade, nos indivíduos sem história de exposição ao ruído ocupacional...

Introduction: The various metabolic and circulatory alterations that are related to noise exposure may cause the onset of several symptoms, including tinnitus. Objective: The purpose of the study was to assess the prevalence of tinnitus complaints in elderly individuals with and without history of occupational noise exposure. Method: This prospective study was conducted in a sample population consisting of 502 individuals aged over 60 years, by anamnesis and audiological evaluation. The variables that were studied were the frequency of tinnitus and the history of occupational noise. Logistic regression was used to control for potential confusion or modifications caused by the effects of the other variables on the associations of interest. Results and Discussion: Tinnitus was reported in 50% of the cases, with tinnitus reported in 40% of the elderly individuals with history of occupational noise exposure, and in 43% of controls (elderly individuals without history of occupational noise exposure). A high frequency of tinnitus was detected in the population under investigation, but there were no statistically significant associations between the presence of tinnitus and history of occupational noise exposure. Conclusion: The results of this study may have occurred due to other factors such as the age of the individuals without history of occupational noise exposure...

Prevalence of tinnitus in elderly individuals with and without history of occupational noise exposure.

Prevalência de perda auditiva e fatores associados na população idosa de Londrina, Paraná: estudo preliminar / Prevalence of hearing loss and associated factors in elderly population in Londrina, Paraná: preliminary study

OBJETIVO: estimar a prevalência de Perda Auditiva (PA), identificando os fatores associados em pacientes idosos de Londrina - PR. MÉTODOS: estudo transversal realizado em amostra populacional de 61 indivíduos com idade igual ou superior a 60 anos, em 2009, através de anamnese e avaliação audiológica. Aplicou-se o teste do Qui-quadrado e o do Risco Relativo com 95 por cento de confiança e valor de p<0,05 para as análises univariadas entre PA e fatores associados. RESULTADOS: de toda a amostra 87,70 por cento apresentaram algum tipo de PA ou rebaixamento de frequências. Destes indivíduos, o tipo de PA de maior prevalência foi a PA sensorioneural, com 63,93 por cento de ocorrência. Entre os hipertensos, 88,88 por cento tiveram PA, sendo este um aumento de 8 chances a mais de hipertensos apresentarem PA. Dos diabéticos, 90 por cento tiveram PA, ou seja, um aumento de 9 chances a mais de diabéticos apresentarem PA. Dos consumidores de álcool, 92,30 por cento apresentaram PA, sendo assim, os consumidores de álcool apresentaram 12 chances a mais de ter PA. A partir da amostra de fumantes, ex-fumantes ou fumantes passivos, 87,09 por cento apresentaram PA, tendo assim, 9 chances a mais de terem PA quando relacionados com não fumantes. CONCLUSÃO: a PA sensorioneural é a mais encontrada, sendo progressiva e proporcionalmente aumentada com o envelhecimento nesta população. Os fatores de risco hipertensão, diabetes, consumo alcoólico e fumo podem predispor as perdas auditivas, principalmente quando associados com a presbiacusia.

PURPOSE: to estimate the prevalence of hearing loss (HL), identifying the factors associated with elderly patients in the city of Londrina - PR. METHODS: cross-sectional study in a population sample with 61 individuals aged over 60 years in Londrina-Pr, 2009, through anamnesis and audiological evaluation. We used the chi-square of relative risk with 95 percent confidence and p-value <0.05 for univariate analysis between HL and associated factors. RESULTS: the whole sample 87.70 percent had some type of hearing loss or lowering of frequencies. Out of these individuals with HL, the type of HL with greater prevalence in this age group was sensorineural HL, with 63.93 percent of occurrence. Out of the sample of hypertensive patients, 88.88 percent had HL, which is an increase of 8 chances to make the hypertensive population to have HL. From the sample of diabetics, 90 percent had HL, an increase of 9 chances to cause the diabetic population to show HL. Consumers of alcohol, 92.30 percent had HL. Thus, consumers of alcohol had 12 more chances to get HL. However, from the sample of smokers, former smokers or passive smokers with daily contact with smokers, from these individuals, 87.09 percent had HL, thus, an increase of 9 chances to have HL. CONCLUSION: the study showed that people over 60 years shows mainly sensory neural HL, and it is a progressive loss and its proportion increased with aging. Risk factors, such as hypertension, diabetes, alcohol consumption and smoking are factors that can predispose to HL, especially when associated with presbycusis.
