The association between occupational noise exposure and hypertension is inconsistent because of an exposure bias caused by outer-ear measurements of noise levels among workers. This study used hearing loss values (HLVs) measured at 4 kHz and 6 kHz in both ears as a biomarker to investigate the chronic effects of noise exposure on hypertension in 790 aircraft-manufacturing workers. Participants were divided into a high hearing loss (HL) group (n = 214; average HLVs ≥ 30 decibel [dB] at 4 kHz or 6 kHz bilaterally; 83.1 ± 4.9 A-weighted decibel [dBA]), a median HL group (n = 302; 15 ≤ average HLVs < 30 dB at 4 kHz or 6 kHz bilaterally; 83.1 ± 4.4 dBA) and a low HL group (n = 274; average HLVs < 15 dB at 4 kHz or 6 kHz bilaterally; 82.2 ± 5.1 dBA) based on the results of pure tone audiometry. Multivariate logistic regressions were used to estimate the risk of hypertension between groups. The prevalence rates of hypertension were significantly higher in the high HL (43.5%; p = 0.021) and median HL (42.1%; p = 0.029) groups than in the low HL group (33.2%). The high HL and median HL workers had 1.48-fold (95% confidence interval [95%CI] = 1.02-2.15; p = 0.040) and 1.46-fold (95%CI = 1.03-2.05; p = 0.031) higher risks of hypertension relative to the low HL workers. Employment duration was significantly and positively correlated with the risk of hypertension among workers with average HLVs ≥ 15 dB at 4 kHz (p < 0.001) and 6 kHz (p < 0.001) bilaterally. Our findings suggest that high-frequency hearing loss is a good biomarker of occupational noise exposure and that noise-induced hearing loss may be associated with the risk of hypertension.

High-frequency hearing loss, occupational noise exposure and hypertension: a cross-sectional study in male workers

Summary Aim To identify likely association between blood hypertension and hearing loss. Design: A non-paired case-control study. Setting: Institutional work carried out at Universidade Norte do Parana, in South Brazil. Material and Method 154 cases and 154 controls, both genders, aged 45 to 64, included in the research after sample estimation. Methodology: Hypertension was verified through blood pressure readings and by a systematized questionnaire about hypertension and the use of medication for blood pressure. Hearing was assessed through tonal threshold audiometrics and audiologic anamneses. Non-conditional logistic regression was used in order to control likely confusion or modification of effect of other variables on interest associations. Results There is a significant association between blood hypertension and hearing loss. Hearing loss in the population under study suggests that hypertension is an accelerating factor of degeneration of the hearing apparatus due to aging. Conclusions The results in this research, through evidence of association between blood hypertension and hearing loss, can allow for an integrated work of cardiologists, nephrologists, otorhinolaryngologists, audiologists and other health professionals concerned with alterations caused by blood hypertension.

Hypertension as a factor associated with hearing loss.

Purpose
Noise exposure is an important and highly prevalent occupational hazard in the construction industry This study examines hearing threshold levels of a large population of Dutch construction workers and compares their hearing thresholds to those predicted by ISO-1999

OBJETIVO: Identificar possivel associacao entre hipertensao arterial e perda auditiva. Foi realizado um estudo do tipo caso-controle nao pareado, na Universidade Norte do Parana, no Sul do Brasil. MATERIAL E METODO: 154 casos e 154 controles, de ambos os sexos com idade variando de 45 a 64 anos foram incluidos na pesquisa apos o calculo da amostra. A hipertensao foi verificada por medicao da pressao arterial e de questionario sistematizado sobre hipertensao e uso de medicamentos para pressao arterial. A audicao foi avaliada por audiometria e anamnese audiologica. A tecnica de regressao logistica nao-condicional foi utilizada com o objetivo de controlar a possivel acao de confusao ou modificacao de efeito exercida por outras variaveis sobre as associacoes de interesse. RESULTADOS : Pode-se verificar que existe associacao significativa entre hipertensao arterial e presenca de perda auditiva e que a perda auditiva observada nesta populacao sugere que a hipertensao arterial age como fator de aceleracao da degeneracao do aparelho auditivo proveniente da idade. CONCLUSOES: Os resultados da presente pesquisa, atraves da constatacao da associacao entre hipertensao e perda auditiva, servirao de base a uma integracao entre cardiologistas, nefrologistas, otorrinolaringologistas, fonoaudiologos e outros profissionais da area de com alteracoes provenientes da hipertensao.

Hipertensão como fator associado à perda auditiva

PURPOSE: To assess the prevalence of tinnitus and possible association with hearing loss, diabetes mellitus and hypertension in elderly. METHODS: Cross-sectional study with individuals older than 60 years who underwent audiological evaluation (pure tone audiometry and history) and answered a comorbidity questionnaire. We evaluated 519 subjects of both genders with a median age of 69 years. Individuals who did not participate in the audiometric test were excluded, then totaling 498 subjects. We applied the appropriate statistical tests to analyze the tinnitus and associated factors. RESULTS: The prevalence of 42.77% of tinnitus was found, being 58.68% bilateral tinnitus and 41.31% unilateral tinnitus. There was a difference between tinnitus and hearing loss, but there was no difference between tinnitus and hypertension and between tinnitus and diabetes mellitus alone. CONCLUSION: The prevalence of tinnitus is significant in the elderly. There are differences between tinnitus and hearing loss, with association between the side affected by tinnitus and the side of hearing loss. Only the association of comorbidity of diabetes mellitus and hypertension is an independent risk factor for tinnitus.

Queixa de vertigem e hipertensão arterial

Although the presence of otologic symptoms associated with diabetes mellitus (DM) have been discussed for six decades, its etiology still remains obscure. Since the association between DM and hearing loss is still a matter of debate, the goal of this paper was to verify the prevalence of hearing loss in patients with DM. Therefore we studied the genesis of DM by a case-control protocol, where pure tone and impedance audiometry were employed. The hearing acuity in 97.2% of the patients with DM showed sensorioneural hearing loss, mainly for high frequencies. We conclude that there was a direct association between DM and hearing loss, mainly for high frequencies.
