Desempenho no teste de Dígitos no Ruído de adultos com sífilis adquirida e/ou HIV

Abstract

Purpose: To study the speech recognition threshold (SRT) of the Digits in Noise Test (DIN test) in Brazilian Portuguese in adults with acquired syphilis and/or HIV in three health services in a county, comparing its application in the diotic and antiphasic modality. Furthermore, it intends to verify the influence of socioeconomic level (SES) and schooling on the LRF result. Method: This is a prospective observational cross-sectional study. The sample was composed of 57 subjects between 18 and 59 years old divided into 4 groups: G1: subjects with acquired syphilis; G2: subjects with syphilis co-occurring with HIV; G3: subjects with HIV and; G4: control group. Anamnesis, otoscopy, socioeconomic questionnaire, DIN test and transient evoked otoacoustic emissions (TOAE) were performed. The Shapiro-Wilks normality test was applied, descriptive analysis was performed and the Kruskall-Wallis test was applied between groups, considering the significance level of 5%. Results: Both NSE and schooling were not statistically significant in the performance of subjects in the RDT in the diotic or antiphasic mode. There was no statistical difference in the SRT between groups in both modalities. In the intra-group analysis, there was a significant difference between the diotic and antiphasic DIN test (p<0.001) in which the diotic resulted in more negative SRT. Conclusion: Syphilis, HIV and co-infection do not influence the LRF of the TDR in the two test modalities. Schooling and SES did not influence performance on DIN test in the population studied, in both modalities. There is a need for further studies with the paired sample.
