ABSTRACT OBJECTIVE To compare the incidence of hearing loss among adults stratified by the occurrence of hypertension, and to investigate the association between hypertension and hearing loss. METHODS Longitudinal observational study, part of the Estudo Longitudinal da Saúde do Adulto (ELSA-Brasil, Longitudinal Study on Adult’s Health). Data from the first and second waves were analyzed, including information from audiological assessment and general health of the subjects. As outcome, we considered the presence of hearing loss (hearing thresholds above 25 dBHL at frequencies from 500 Hz to 8 kHz) and, as exposure variable, hypertension (report of medical diagnosis of hypertension; and/or use of drugs to treat hypertension; and/or pressure systolic blood pressure ≥ 140 mmHg; or diastolic blood pressure ≥ 90 mmHg). As covariables for adjustment were considered: sex, age, education, race / ethnicity, income, smoking, diabetes, and occupational exposure to noise. Poisson regression analysis was conducted, estimating the crude and adjusted relative risks, with 95% confidence intervals, in order to assess the factors associated with hearing loss. RESULTS In crude analyses, the incidence of hearing loss was higher for subjects with hypertension (9.7% versus 5.4%). The crude relative risks for hearing loss was almost double (1.93; 95%CI: 1.10–3.39) for subjects with hypertension in the right ear. In the adjusted analyses, the relative risks was not significant for the hypertension variable (1.42; 95%CI: 0.75–2.67). Being 60 years or older (RR: 5.41; 95%CI: 2.79–10.50) showed a statistically significant association with hearing loss, indicating that older adults have higher relative risks for hearing loss. CONCLUSION In the adjusted analyses controlled for multiple risk factors there was no association between hypertension and hearing loss. The dichotomous variable age (being 60 years or older), on the other hand, has shown a significant association with hearing loss.

RESUMO Objetivo Analisar o uso do teste dicótico de dígitos (TDD) como método de triagem e comparar seu desempenho com questionário de autopercepção e demais testes comportamentais do processamento auditivo central (PAC). Método Estudo do tipo transversal, retrospectivo e com análise de prontuários. Foram analisados 66 prontuários de crianças com idade de 8 a 11 anos, sendo as mesmas divididas em grupo controle (G1), constituído por 34 crianças que não apresentaram alteração no TDD e o grupo estudo (G2), por 32 crianças que apresentaram alteração no TDD. Foi utilizado o questionário Scale of Auditory Behaviors (SAB). Além de testes comportamentais que avaliaram as habilidades auditivas de localização, fechamento, figura-fundo, ordenação e resolução temporal. Resultados Os indivíduos do G2 apresentaram maiores percentuais de alteração em todos os instrumentos, com exceção do teste fala com ruído. Houve associação estatisticamente significante entre as categorias de desempenho do TDD com as categorias do questionário SAB (p-valor 0,022) e da Avaliação simplificada do PAC (p-valor<0,001).O TDD apresentou correlação significante com o questionário SAB e com todos os testes do PAC utilizados, em pelo menos uma das orelhas analisadas. Conclusão Conclui-se o TDD pode ser utilizado como método triagem do transtorno do processamento auditivo central na avaliação audiológica básica, uma vez que houve associação no seu desempenho com o questionário de autopercepção SAB.Além de correlação, especialmente na orelha esquerda, com os testes comportamentais aplicados para realizar o diagnóstico do transtorno do PAC.

ABSTRACT Purpose To analyze the use of the Dichotic Digit Test (DDT) as a screening method and to compare its performance with a self-perception questionnaire and other Central Auditory Processing (CAP)behavioral tests. Methods Cross-sectional, retrospective study with analysis of medical records. The study analyzed 66 medical records of children aged 8 to 11 years, and divided them into control group (G1), consisting of 34 children who did not show changes in the DDT, and the study group (G2) with 32 children who showed changes in the DDT. The Scale of Auditory Behaviors (SAB) questionnaire was used in addition to behavioral tests that assessed the auditory abilities of localization, closure, figure-ground, temporal ordering and resolution. Results Individuals in G2 showed higher percentages of changes in all instruments, except for the speech-in-noise test. There was a statistically significant association between the DDT performance categories with the categories of the SAB questionnaire (p-value 0.022) and the simplified CAP assessment (p-value<0.001). The DDT showed a significant correlation with the SAB questionnaire and with all CAP tests used in at least one of the analyzed ears. Conclusion In conclusion, the DDT can be used as a screening method for central auditory processing disorder in basic audiological assessment as there was an association in its performance with the self-perception in the SAB questionnaire, in addition to correlation, especially in the left ear, with behavioral tests applied to diagnose CAPD.

RESUMO Objetivo Analisar o desempenho das crianças sem alteração do processamento auditivo central no teste de fala comprimida. Método Trata-se de um estudo do tipo descritivo, observacional, transversal. Participaram do estudo 22 crianças com idade entre 7 e 11 anos, normo-ouvintes, sem transtorno do processamento auditivo central. Para descartar esse transtorno, foram aplicados o questionário Scale of Auditory Behaviors, a avaliação simplificada do processamento auditivo e o teste dicótico de dígitos na etapa de integração binaural. Nas crianças sem alteração, foi aplicado o teste de fala comprimida. Resultados Os indivíduos apresentaram melhor desempenho na lista de monossílabos do que na de dissílabos, apesar de não haver diferença significativa. Não houve influência da ordem de apresentação das listas, das variáveis gênero e orelha no desempenho do teste. Em relação à idade, apenas na lista de dissílabos houve diferença no desempenho. Conclusão Foi possível concluir que a média de acertos das crianças no Teste de Fala Comprimida foi inferior aos achados na literatura nacional em adultos. Houve diferença no desempenho do Teste de Fala Comprimida com a idade apenas na lista de dissílabos. Não houve diferença quanto à ordem de apresentação das listas de aplicação nem em relação ao tipo de estímulo.

ABSTRACT Purpose To analyze the performance of children without alteration of central auditory processing in the Time-compressed Speech Test. Methods This is a descriptive, observational, cross-sectional study. Study participants were 22 children aged 7-11 years without central auditory processing disorders. The following instruments were used to assess whether these children presented central auditory processing disorders: Scale of Auditory Behaviors, simplified evaluation of central auditory processing, and Dichotic Test of Digits (binaural integration stage). The Time-compressed Speech Test was applied to the children without auditory changes. Results The participants presented better performance in the list of monosyllabic words than in the list of disyllabic words, but with no statistically significant difference. No influence on test performance was observed with respect to order of presentation of the lists and the variables gender and ear. Regarding age, difference in performance was observed only in the list of disyllabic words. Conclusion The mean score of children in the Time-compressed Speech Test was lower than that of adults reported in the national literature. Difference in test performance was observed only with respect to the age variable for the list of disyllabic words. No difference was observed in the order of presentation of the lists or in the type of stimulus.
