RESUMO
Abstract Introduction: Chronic diseases can act as an accelerating factor in the auditory system degeneration. Studies on the association between presbycusis and diabetes mellitus and systemic arterial hypertension have shown controversial conclusions. Objective: To compare the initial audiometry (A1) with a subsequent audiometry (A2) performed after a 3 to 4-year interval in a population of elderly patients with diabetes mellitus and/or systemic arterial hypertension, to verify whether hearing loss in these groups is more accelerated when compared to controls without these clinical conditions. Methods: 100 elderly individuals participated in this study. For the auditory threshold assessment, a previous complete audiological evaluation (A1) and a new audiological evaluation (A2) performed 3-4 years after the first one was utilized. The participants were divided into four groups: 20 individuals in the diabetes mellitus group, 20 individuals in the systemic arterial hypertension group, 20 individuals in the diabetes mellitus/systemic arterial hypertension group and 40 individuals in the control group, matching them with each study group, according to age and gender. ANOVA and Kruskal-Wallis statistical tests were used, with a significance level set at 0.05. Results: When comparing the mean annual increase in the auditory thresholds of the A1 with the A2 assessment, considering each study group and its respective control, it can be observed that there was no statistically significant difference for any of the frequencies for the diabetes mellitus group; for the systemic arterial hypertension group, significant differences were observed after 4 kHz. For the diabetes mellitus and systemic arterial hypertension group, significant differences were observed at the frequencies of 500, 2 kHz, 3 kHz and 8 kHz. Conclusion: It was observed that the systemic arterial hypertension group showed the greatest decrease in auditory thresholds in the studied segment when compared to the other groups, suggesting that among the three studied conditions, hypertension seems to have the greatest influence on hearing.
Resumo: Introdução: Doenças crônicas podem atuar como fator de aceleração na degeneração do sistema auditivo. Os estudos sobre a associação da presbiacusia com o diabetes mellitus e com a hipertensão arterial sistêmica mostraram conclusões controversas. Objetivo: Comparar a audiometria inicial (A1) com uma audiometria sequencial (A2) feita com um intervalo de três a quatro anos em uma população de idosos portadores de diabetes mellitus e/ou hipertensão arterial sistêmica, a fim de saber se a perda de acuidade auditiva nesses grupos é mais acelerada comparados com controles sem essas condições clínicas. Método: Participaram deste estudo 100 idosos. Para a análise dos limiares auditivos, foram usadas: uma avaliação audiológica completa feita anteriormente (A1) e uma nova avaliação audiológica (A2) feita após três a quatro anos da primeira. Os participantes foram distribuídos em quatro grupos: 20 indivíduos no grupo com diabetes mellitus, 20 no grupo hipertensão arterial sistêmica, 20 no grupo diabetes mellitus/hipertensão arterial sistêmica e 40 indivíduos no grupo controle, foram pareados com cada grupo de estudo, de acordo com as características referentes a idade e sexo. Foram usados os testes estatísticos Anova e Kruskal-Wallis, com nível de significância de 0,05. Resultados: Na comparação da média de aumento anual dos limiares auditivos da avaliação A1 com a avaliação A2, considerando cada grupo estudo e seu respectivo controle, pode-se observar que para o grupo diabetes mellitus não houve diferença estatisticamente significante para qualquer das frequências; para o grupo hipertensão arterial sistêmica foram observadas diferenças significantes a partir de 4 kHz. Já para o grupo diabetes mellitus/hipertensão arterial sistêmica foram observadas diferenças significantes nas frequências de 500, 2k, 3k e 8 kHz. Conclusão: Verificou-se que o grupo hipertensão arterial sistêmica foi o que apresentou maior queda dos limiares auditivos no segmento estudado, quando comparado com os outros grupos, sugeriu que entre as três condições estudadas a hipertensão parece ser a que teve maior influência sobre a audição.

INTRODUCTION: Chronic diseases and metabolic changes may act as accelerating factor in the degeneration of the auditory system due to age. However, studies involving an association between hearing loss and diabetes mellitus (DM) and hypertension (HA) in the elderly have shown controversial conclusions. Thus, further studies on this topic are needed in order to elucidate the effect of these chronic diseases on the auditory system. AIM: To compare the hearing thresholds of elderly patients with DM, HA and DM + HA with a control group (CG). METHODS: Retrospective study was conducted through survey charts of 80 elderly people with full hearing assessment, between 2008 and 2012. Subjects were divided into four groups: DM, HA, DM + HA and without chronic diseases known (CG). The ANOVA, Tukey and Mauchly tests, with a significance level of 0.05, were used. RESULTS: There was no statistically significant difference between the ears, which are grouped. Comparisons between the means of hearing thresholds of CG and DM or HA showed no statistically significant differences. However, a statistically significant difference in the comparison between these three groups and DM + HA group for several of the frequencies evaluated was observed. CONCLUSION: It was found that older adults with DM and hypertension associated showed greater hearing impairment in comparison with the other groups, suggesting a synergistic effect of the two chronic diseases on hearing.

RESUMO Introdução: Doenças crônicas e alterações metabólicas podem atuar como fator de aceleração na degeneração do sistema auditivo decorrente da idade. No entanto, estudos envolvendo a associação entre a perda auditiva com a diabetes mellitus (DM) e com a hipertensão arterial (AH) em idosos mostraram conclusões controversas. Sendo assim, novos estudos sobre essa temática são necessários, a fim de elucidarmos o efeito dessas doenças crônicas sobre o sistema auditivo. Objetivo: Comparar os limiares auditivos de idosos portadores de DM, de HA e de DM+AH com um grupo controle (GC). Métodos: Estudo retrospectivo realizado por meio de levantamento de prontuários de 80 idosos com avaliação audiológica completa, entre 2008 e 2012. Os idosos foram distribuídos em quatro grupos: portadores de DM, portadores de AH, portadores de DM+AH e sem doenças crônicas conhecidas (GC). Foram utilizados os testes estatísticos ANOVA, Tukey e Mauchly, com nível de significância de 0,05. Resultados: Não houve diferença estatisticamente significante entre as orelhas, sendo esses resultados agrupados. As comparações entre as médias dos limiares auditivos dos grupos GC e DM ou AH não mostraram diferenças estatisticamente significantes, entretanto houve diferença estatisticamente significante na comparação entre esses três grupos e o grupo DM+AH para várias das frequências da audiometria avaliadas. Conclusão: Verificou-se que idosos com DM e AH associados apresentaram maior comprometimento auditivo com relação aos outros grupos, sugerindo um efeito sinérgico das duas doenças crônicas sobre a audição.
