- Hearing Loss and Cognitive Function: Baseline Findings From the Brazilian Longitudinal Study of Adult Health: ELSA-Brasil(2022) SAMELLI, Alessandra G.; SANTOS, Itamar S.; DEAL, Jennifer A.; BRUNONI, Andre R.; PADILHA, Fernanda Y. O. M. M.; MATAS, Carla G.; MOREIRA, Renata R.; RABELO, Camila M.; MURANO, Emi Z.; BENSENOR, Isabela J.; LOTUFO, Paulo A.; SUEMOTO, Claudia K.Objective: Hearing loss (HL) has been associated with cognitive impairment in high-income countries. However, no study has investigated this association in low- and middle-income countries. Therefore, our aim was to investigate the association between cognitive function and HL in the Brazilian Longitudinal Study of Adult Health. Design: Cross-sectional analysis of Longitudinal Study of Adult Health (ELSA-Brasil) with 802 individuals (35-74 years old). Hearing was measured using pure-tone audiometry. A pure-tone average (s) of thresholds at 500, 1000, 2000, and 4000 Hz was calculated. HL was defined as a PTA above 25 dB in the better ear or either ear, as a categorical variable. Cognitive performance was measured using the Consortium to Establish a Registry for Alzheimer's Disease word list memory test, the semantic and phonemic verbal fluency (VF) tests, and the Trail Making test version B. To investigate the association between cognitive performance and HL, we used linear regression models adjusted for sociodemographic and clinical variables. Results: Of the total of participants, 7.6% had HL. After adjustment for sociodemographic and health confounding variables, only VF was associated with HL; a 10 dB increase in the PTA in the better ear was associated with worse performance in the phonemic VF test (beta = -0.115 [95% CI, -0.203 to -0.027], p = 0.01). We found a significant interaction between HL and age in the VF domain (p = 0.01). HL was related to poor VF performance among older adults only. Conclusion: In a community-dwelling sample of most middle-aged adults, objectively measured HL was associated with lower VF. These results should be evaluated with caution, given the likelihood of residual confounding and the fact that only VF showed an association with HL.
- Effects of Noise and Chemical Exposure on Peripheral and Central Auditory Pathways in Normal-hearing Workers(2022) TRABANCO, Julio C. S.; MORITA, Bruno; MATAS, Carla Gentile; PAIVA, Karina Mary de; MOREIRA, Renata R.; SANCHES, Seisse G. G.; SAMELLI, Alessandra G.Objectives: To assess the effects of noise and chemical exposure on peripheral and central auditory pathways in normal-hearing workers exposed to chemicals or high noise levels and compare the groups with each other and with workers not exposed to either of these agents. Methods: A total of 54 normal-hearing workers were divided into three groups (chemical, noise, control) and submitted to the following assessments: conventional and extended high-frequency pure-tone audiometry; transient and distortion-product otoacoustic emissions, the inhibitory effect of the efferent auditory pathway; and Staggered Spondaic Word (SSW) and Pitch Pattern Sequence (PPS) test. Results: There were no significant differences between the groups in extended high-frequency hearing thresholds. Significantly lower amplitudes were observed in the noise group for otoacoustic emissions. There were significantly more absences of the inhibitory effect of the efferent system in the noise group. There was no difference between the groups in the SSW test, while in PPS, the noise group performed worse than the control group. Conclusion: These findings suggest that noise exposure produced deleterious effects on the workers' peripheral and central auditory systems, despite their normal hearing thresholds. The chemical group did not have significantly different results from those of the control group. It is important that individuals exposed to noise or chemicals have their auditory pathways monitored with complementary assessments.
- ELSA-Brasil: a 4-year incidence of hearing loss in adults with and without hypertension(2022) PADILHA, Fernanda Yasmin Odila Maestri Miguel; OENNING, Nagila Soares Xavier; SANTOS, Itamar de Souza; RABELO, Camila Maia; MOREIRA, Renata Rodrigues; BENSENOR, Isabela M.; LOTUFO, Paulo A.; SAMELLI, Alessandra GiannellaOBJECTIVE: 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 Saude 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.
- Noise Exposure, Headsets, and Auditory and Nonauditory Symptoms in Call Center Operators(2022) SILVA, Barbara Gabriela; GONZAGA, Denise; ROCHA, Clayton Henrique; GOMES, Raquel Fornaziero; MOREIRA, Renata Rodrigues; BISTAFA, Sylvio R.; SAMELLI, Alessandra GiannellaPurpose: This study evaluates the exposure of call center operators (CCOs) to occupational noise, its association with auditory and nonauditory symptoms, and the feasibility of monaural and binaural headsets. Method: We measured the noise exposure sound pressure levels (SPLs) with the microphone-in-real-ear technique and administered a questionnaire on auditory/nonauditory symptoms and headset preference. Results: We assessed 79 CCOs with normal hearing. Overall, 98.7% of the participants reported at least one auditory symptom, and 88.6% reported at least one nonauditory symptom after using the headset. We found significant associations between the headset volume setting and the number of auditory and nonauditory symptoms and between sharp increases in sound level and tinnitus. The microphone-in-real-ear diffuse-field-related SPLs with monaural headsets (85.5 dBA) were significantly higher than those with binaural headsets (83.1 dBA). Binaural headsets were the preference of 84.8% of the subjects. The SPLs of the binaural headsets were significantly lower than those of the monaural headsets in the subjects who preferred the binaural headsets. Conclusions: CCOs with normal hearing reported auditory and nonauditory symptoms, highlighting the need for attention and further investigation. The binaural headsets were preferable, as they were associated with a lower SPL and a higher call quality.
