RESUMO

Objective: A Meta-analysis was used to evaluate the high frequency hearing loss detection rate, its area and time distributions in occupational noise exposed workers in China to provide evidence for the prevention and control of occupational noise-induced deafness. Methods: From February to April 2020, the number of hearing tests and the number of binaural high frequency average hearing threshold ≥40 dB of workers exposed to noise in key occupational disease monitoring and occupational health risk assessment project in China was collected from China National Knowledge Infrastructure (CNKI) , VIP database and PubMed database. The retrieval time was set from the establishment of the database to February 28, 2020. The R 3.6.2 software was used to calculate the pooled high frequency hearing loss detection rate. Results: A total of 28 studies, included 34 data and 1259571 occupational noise exposed workers, were enrolled. The articles covered 16 provinces in 2015-2018. The pooled high frequency hearing loss detection rate in occupational noise exposed workers was 9.45% (95%CI: 7.64%-11.64%) . The high frequency hearing loss detection rate (10.54%) was higher in 2018 than other years (2017: 10.17%, 2016: 9.21%, 2015: 7.88%) . The high frequency hearing loss detection rate (12.23%) was higher in central China than in eastern (10.21%) , western (7.91%) and north-eastern (5.21%) China. Conclusion: The overall high frequency hearing loss detection rate in occupational noise exposed workers is generally high in China. It is important to strengthen the hearing protection in occupational noise exposed workers to facilitate the occupational noise-induced deafness prevention and control in China.

RESUMO

Objective: To explore the effect of different diagnostic criteria on occupational noise-induced deafness (Onid) , and to provide theoretical basis for the revision of ONID diagnostic criteria. Methods: From January 2016 to January 2018, the physical examination results of noise-exposed workers during occupational health examination in Qingyuan Occupational Disease Prevention and Treatment Hospital were retrospectively investigated in September 2019, with Gbz 49-2014《diagnosis of occupational noise deafness》as the study object, 471 workers suspected of Onid were weighted with different combinations of high frequency hearing threshold, and the better ear weight was calculated, compared with the diagnostic criteria of 2007 and 2014, the degree of hearing loss was evaluated. SPSS 22.0 was used for statistical analysis, χ(2) test was used for counting data, and non-parametric test was used for measuring bias data. Results: The average age of 471 subjects was (40.32±7.01) years, and the average age of exposure to noise was (7.11±3.44) years. On the basis of the 2007 edition diagnostic standard, the suspected ONID diagnostic rate of different high frequency auditory threshold was increased by 16.35% and 30.15% at 3.0 kHz, 6.0 kHz increased by 20.17%, 3.0 kHz+4.0 kHz increased by 22.29%, 3.0 kHz+6.0 kHz increased by 17.20%, 4.0 kHz+6.0 kHz increased by 25.27%, the differences were statistically significant (P<0.05) , the frequency of 3.0 kHz+4.0 kHz+6.0 kHz increased by 22.29%. Using the 2014 edition diagnostic standard, the diagnostic rate of Onid was reduced by 30.15% and 13.80%, 6 kHz is 9.98% lower, 3.0 kHz+4.0 kHz is 7.86% lower, 3.0 kHz+6.0 kHz is 12.95% lower, 4.0 kHz+6.0 is 4.88% lower, the high frequency of 3.0 kHz+4.0 kHz+6.0 kHz decreased by 7.86%, the differences were statistically significant (P<0.05) . Conclusion: The diagnosis rate of suspected Onid is increased by weighting different high frequency hearing threshold, in which the weighted 4kHz high frequency has the greatest influence on the result, and the weighted 3 kHz high frequency has the least.

RESUMO

Objective: To understand the basic situation of noise hazards in wood furniture manufacturing, stone processing and special equipment manufacturing industries in Shenzhen City, and to provide basis for preventing and controlling noise hazards. Methods: In August 2019, stratified random sampling ws used to select 21 wood funiture manafacturing, 15 stone processing and 24 special equipment manufactruing as survey object. Through the methods of occupational health field investigation, noise intensity measurement and occupational health examination data collection, the noise hazards of 60 enterprises in three industries were statistically analyzed. Results: There were 154, 44 and 113 noise detection points in wood furniture manufacturing, stone processing and special equipment manufacturing enterprises, and 101, 27 and 78 out of standard points respectively, and the exceeding standard rates were 65.6% (101/154) , 61.4% (27/44) and 69.0% (78/113) , respectively. There were 1670, 172 and 856 workers exposed to noise in the three industries. Among them, 1198, 134 and 703 people had taken occupational health examination. The physical examination rates were 71.7% (1198/1670) , 77.9% (134/172) and 82.1% (703/856) , respectively. The abnormal rates were 19.1% (229/1198) , 51.5% (69/134) and 37.8% (266/703) , respectively. Conclusion: High intensity noise working environment, too long noise exposure time, incorrect wearing of personal protective equipment and neglect of occupational health examination are important reasons for hearing loss of noise exposed personnel.

RESUMO

Objective was to study single-nucleotide polymorphisms (SNP) in CAT, NCL, HSPA1L, PCDH15, and PON2 genes and their associations with hearing impairment among the people working among noise-exposed workers of the mashine-building plant (JSC «Krasmash¼, Krasnoyarsk, Eastern Siberia, Russia). MATERIALS AND METHODS: The 443 employees of Krasmash JSC, who have been working under conditions of increased noise for at least 1 year, were surveyed and examined. A hearing study was performed by speech and tonal audiometry. Tonal audiometry was carried out in accord with according to a standard method in the frequency range 125-8000 Hz. People with chronic hearing impairment, survivors of meningitis and family history of hearing impairment were excluded from the study. The allelic composition of the studied genes was determined in the remaining group of 288 workers (study group). Polymorphisms were detected using bioluminescent method, developed by the authors earlier. The study group comprised 122 people with hearing impairment (experimental group) and 166 people without impairment (control group). RESULTS: The genotyping results of on allelic variants rs494024 (CAT), rs7598759 (NCL), rs2227956 (HSPA1L), rs7095441 (PCDH15) and rs7785846 (PON2) showed that their frequencies in the study group did not differ and were comparable with those for the European population. No statistically significant differences were revealed in the distribution of the genotypes of the studied mutations between the experimental and control groups. Also no statistically significant associations we found between hearing impairment and availability of two or several SNPs, or these SNPs and clinical characteristics of the disease (degree of hearing impairment, tinnitus). In the group of workers with an experience of 5 to 16 years, an association was found for hearing impairment and SNP rs494024, as well as when it is combined with rs7598759. CONCLUSIONS: The associations between SNP rs7598759, rs2227956, and rs7095441 and hearing impairment were not found. In the group of workers with 5-16 year experience, this association was found for SNP rs494024, as well as when it is combined with rs7598759. Discovered associations require further study.

RESUMO

Objective: To investigate the risk of occupational hearing loss caused by noise exposure in an automobile parts manufacturing enterprise. Methods: In June 2019, an automobile parts manufacturing enterprise in Huizhou City was selected to conduct occupational hygiene field investigation, and occupational health investigation and occupational hazards detection were carried out in the workplace. 395 workers with 8-hour working day equivalent sound level (L(ex·8 h)) ≥85 dB (a) were selected as the research objects. The occupational noise exposure risk assessment method was used to assess the noise exposure risk of L(ex·8 h)≥85 dB (a) , and the risk of high-frequency hearing loss and occupational noise deafness caused by noise exposure were evaluated when the working years were 10, 20, 30, 35 and 40. Results: When the exposure years were less than or equal to 30 years, the risk of high-frequency hearing loss of bearing pedestal final examiners was medium risk, and the risk of other positions was acceptable; the highest risk of noise deafness was the bearing pedestal final examiner, and the risk classification was higher, and the other types of work were negligible risk and acceptable risk. When the exposure years are more than 30 years, the risk classification of high-frequency hearing loss of bearing pedestal final inspection workers is high-risk, and the risk classification of other types of work is medium risk; the highest risk of noise deafness is the bearing pedestal final inspection workers, and the risk classification is higher risk, and the other types of work are medium risk. Conclusion: The enterprise should pay attention to the risk of occupational hearing loss caused by noise exposure, especially the bearing pedestal final inspection workers, and strengthen the hearing protection of noise exposed people.

RESUMO

A number of epidemiological studies report an association between occupational noise exposure and arterial hypertension. Existing systematic reviews report conflicting results, so we conducted an updated systematic review with meta-analysis. We registered the review protocol with PROSPERO (registration no.: CRD 42019147923) and searched for observational epidemiological studies in literature databases (Medline, Embase, Scopus, Web of Science). Two independent reviewers screened the titles/abstracts and full texts of the studies. Two reviewers also did the quality assessment and data extraction. Studies without adequate information on recruitment, response, or without a comparison group that was exposed to occupational noise under 80 dB(A) were excluded. The literature search yielded 4583 studies, and 58 studies were found through hand searching. Twenty-four studies were included in the review. The meta-analysis found a pooled effect size (ES) for hypertension (systolic/diastolic blood pressure ≥140/90 mmHg) due to noise exposures ≥80 dB(A) of 1.81 (95% CI 1.51-2.18). There is no substantial risk difference between men and women, but data concerning this question are limited. We found a positive dose-response-relationship: ES = 1.21 (95% CI 0.78-1.87) ≤ 80 dB(A), ES = 1.77 (95% CI 1.36-2.29) >80-≤85 dB(A), and ES = 3.50 (95% CI 1.56-7.86) >85-≤90 dB(A). We found high quality of evidence that occupational noise exposure increases the risk of hypertension.

RESUMO

Objective: To provide scientific evidence for the prevention and control strategies of noise-induced deafness, to analyze the epidemiological characteristics of the occupational noise-induced deafness diagnostic applicants in Guangzhou city during 2011-2018. Methods: In March 2019, by consulting the occupational disease diagnosis records, we investigated the distribution of all 471 occupational noise-induced deafness diagnostic applicants in Guangzhou Occupational Disease Prevention and Treatment Center from 2011 to 2018. Frequency and constituent ratio were used to describe the distribution. Results: From 2011 to 2018, there were 471 cases of occupational noise-induced deafness diagnostic applicants and 211 of the applicants were diagnosed as occupational noise-induced deafness (44.8%, 211/471) . The new cases were mainly mild (83.9%, 177/211) , with the predilection age of 40.0-49.0 years old (41.7%, 88/211) and the predilection seniority of 5.0-9.9 years (38.9%, 82/211) . Among the new cases, there were mainly males (88.6%, 187/211) . Most of the new cases were distributed in Nansha district (23.2%, 49/211) , Huangpu district (22.7%, 48/211) and Panyu district (21.8%, 46/211) . Besides, in terms of industry distribution, they were concentrated in manufacturing industry (82.0%, 173/211) . The scale of enterprises was mainly medium-sized (42.7%, 90/211) , and the most of their economic type was domestic-funded (40.8%, 86/211) . Conclusion: Although most of the newly diagnosed cases of occupational noise deafness in Guangzhou are mild, they still need to be paid attention to and strengthen the noise industry protection education.

RESUMO

Excessive noise levels are a prevalent issue in food processing operations and, although there have been numerous studies on occupational noise, no single study has used a concurrent mixed-methods approach. Employing this study design allows for an understanding of the level of convergence (similarity) between measured noise levels and workers' attitudes and perceptions towards noise. This, in turn, allows for the identification of potential challenges with respect to the implementation of hearing conservation efforts. In this study, spot noise measurements were collected using a sound level meter. One-on-one interviews were conducted with workers to determine attitudes and perceptions towards noise in their workplaces. Subsequently, the results of the noise measurements (quantitative data) were integrated with the survey responses (qualitative data) to identify convergence. The majority of the noise measurements were found to exceed 85 dBA-the criterion mandated by the local occupational health and safety legislation. Although all study participants felt that it was noisy in the workplace, a large proportion of respondents indicated that the noise was not bothersome. With workers' perception being contradictory to the measured noise levels, it is a challenge to implement hearing conservation measures unless changes are made to raise the awareness of the risks associated with excessive noise exposure.

RESUMO

La relación entre la exposición a los ruidos y la pérdida auditiva se considera desde hace muchos años. La comunidad odontológica no está exenta de este problema, ya que los profesionales trabajan a diario, y durante tiempos prolongados, con instrumentos ruidosos. Esta revisión bibliográfica tiene como propósito realizar una actualización acerca del riesgo de pérdida auditiva inducida por ruido en el personal que trabaja en la clínica odontológica. En la actualidad, se afirma que los odontólogos y el personal en la clínica dental corren el riesgo de contraer diversas patologías auditivas ­como es el caso de la hipoacusia­ debido al ruido que producen los equipos de alta velocidad. Las enfermedades profesionales del tipo auditivas que se abordan en este trabajo constituyen factores que comprometen no solo el buen estado de salud de los odontólogos y demás profesionales, sino su calidad de vida (AU)


The relationship between noise exposure and hearing loss has been known for many years. The dental community is not exempt from this problem, because they work every day and for long periods of time with noisy instruments. This literature review aims to update the risk of noise-induced hearing loss in personnel working in the dental clinic. The risk to which dentists and staff in the dental clinic are subjected to the high-speed and other noisy equipment is well known, and that can cause various auditory problems such as hearing loss. The occupational diseases of the auditory type that were addressed in this article constitute factors that compromise not only the good state of health of dentists and other professionals who work in similar conditions, but also in their quality of life (AU)

RESUMO

Objective: To investigate the combined effect of noise and hand-transmitted vibration on noise-induced hearing loss (NIHL) in the automobile manufacturing industry. Methods: From September 2018 to January 2019, cluster sampling was used to select 998 workers in an automobile factory as study subjects, among whom 352 workers exposed to noise alone were enrolled as noise group, 342 workers exposed to noise and hand-transmitted vibration were enrolled as combined effect group, and 304 workers without exposure to occupational hazardous factors were enrolled as control group. A questionnaire survey and pure tone audiometry were performed for all study subjects. An analysis of variance was used for comparison of continuous data between groups, and the chi-square test was used for comparison of categorical data between groups; a ordinal polytomous logistic regression analysis was used to investigate the influencing factors for NIHL (with 0.05 as the inclusion criteria and 0.10 as the exclusion criteria for independent variables) . Results: There was a significant difference in L(Aeq, 8 h) between groups (P<0.05) ; the noise group and the combined effect group had a significantly higher L(Aeq, 8 h) than the control group (P<0.05) , while there was no significant difference in L(Aeq, 8 h) between the noise group and the combined effect group (P>0.05) . The control group had a significantly lower detection rate of hearing loss than the noise group and the combined effect group (P<0.0125) , and the combined effect group had a significantly higher detection rate of hearing loss than the noise group (P<0.0125) . The ordinal polytomous logistic regression analysis showed that after adjustment for confounding factors such as age, working years, sex, smoking, and drinking, both noise exposure and exposure to both noise and hand-transmitted vibration had an influence on workers' hearing (P<0.05) , and the workers exposed to both noise and hand-transmitted vibration had a higher risk of hearing loss than those exposed to noise alone. Conclusion: There may be a combined effect of noise and hand-transmitted vibration in the automobile manufacturing industry, which can increase the risk of NIHL in workers.

RESUMO

Background: Occupational noise-induced hearing loss (ONIHL) is one of the most common yet preventable occupational diseases. The aim of this study was to estimate the economic burden of ONIHL in the Australian working population by quantifying and monetising ONIHL-related loss of Quality Adjusted Life Years (QALY) and Productivity Adjusted Life Years (PALYs). Methods: We simulated the number of moderate-to-severe ONIHL by multiplying the age-specific prevalence of occupational noise exposure by the excess risks of ONIHL. Life table modelling was applied to workers with ONIHL. The QALY and PALY weights attributable to hearing loss were sourced from published data. The 2016 Gross Domestic Product per full-time equivalent worker in Australia was used to estimate the cost of productivity loss due to ONIHL. The cost due to the loss of well-being was quantified using willingness to pay thresholds derived from an Australian longitudinal study. Results: Under current occupational noise exposure levels in Australia, we estimated that over 80,000 male workers and over 31,000 female workers would develop ONIHL over 10 years of exposure. Following this cohort until the age of 65 years, the estimated loss of QALYs and PALYs were 62,218 and 135,561 respectively, with a projected loss of AUD 5.5 billion and AUD 21.3 billion due to well-being and productivity loss, respectively. Reducing noise exposure at work would substantially reduce the economic burden of ONIHL. Conclusion: ONIHL imposes substantial burden on Australian economy. Interventions to reduce occupational noise exposure are warranted.

RESUMO

OBJECTIVE: To analyze the effect of occupational noise exposure on hypertension in male steel workers. METHODS: The general information, noise exposure and blood pressure were collected through questionnaires and physical examinations. Chi-square test was used to investigate the prevalence of hypertension under different cumulative noise exposure, and the effect of noise exposure and other factors on hypertension was analyzed by the restrictive cubic spline(RCS) combined with multivariatenon-condition Logistic regression model. RESULTS: The prevalence of hypertension in noise exposure group was higher than that in noise non-exposure group(P<0. 001). After adjusting for multiple factors, the restricted cubic spline model showed a dose-response relationship between cumulative noise exposure(CNE) and hypertension(overall correlation χ~2=75. 76, P<0. 001, and nonlinear χ~2=24. 17, P<0. 001). Compared with the steel workers exposure to lowest dose, the risk of hypertension of steel workers exposure to 82-94 and 95-107 dB(A) in group was 1. 81(95%CI 1. 31-2. 52) times and 2. 60(95%CI 1. 84-3. 68) times. CONCLUSION: There is a non-linear dose-response relationship between cumulative noise exposure and hypertension.

RESUMO

Objective: To investigate the characteristics of asymmetric hearing loss in left and right ears of patients with occupational noise-induced deafness and to explore the possible causes of asymmetric hearing loss. Methods: A total of 423 cases of occupational noise-induced deafness diagnosed in Guangdong Province Hospital for Occupational Disease Prevention and Treatment from May 2015 to May 2018 were investigated retrospectively. On the basis of three consecutive pure tone audiometry (PTA) with intervals of more than 3 d in hospital, the minimum of hearing threshold of each frequency and the frequency response threshold of auditory steady-state response (ASSR) , and based on the GBZ 49-2014 "Diagnosis of Occupational Noise-induced Deafness". The statistical analysis of Wilcoxon signed rank test and Spearman correlation analysis were carried out by nonparametric test. The hearing threshold weight of PTA and the response threshold of ASSR were tested and compared from different dimensions according to sex, age, length of service of exposure noise, diagnosis grade and so on. Results: There were 369 male (87.23%) and 54 female (12.77%) ; the age was (41.8±7.6) years; the length of service was (10.1±6.2) years. The weighted values of left ear PTA and ASSR were higher than those of right ear (P<0.001) . The weighted values of left ear PTA and ASSR were higher than those of right ear (P<0.05) in men, patients with age ≤ 40 and 41-60 years, 3-9 years of service, and patients with mild grade (P<0.05) . After the equalization of characteristic variables, the weighted values of left ear PTA and ASSR were also higher than those of right ear (P<0.05) . There was a positive correlation between the weighted value of PTA and the weighted value of ASSR (P<0.001) . Conclusion: There is asymmetry in hearing loss of patients with occupational noise deafness, and hearing loss in the left ear is higher than that in the right ear.

RESUMO

Abstract Introduction: South Africa has a high prevalence of co-existing tuberculosis and HIV. As ototoxicity linked to the treatments for these conditions occurs with concomitant exposure to other ear toxins such as hazardous noise exposure, it is important to investigate the combination impact of these toxins. Limited published evidence exists on the co-occurrence of these conditions within this population. Objectives: The objective of this study was to compare the hearing function of gold miners with (treatment group) and without (non-treatment group) the history of tuberculosis treatment, in order to determine which group had increased risk of noise induced hearing loss. Furthermore, possible influence of age and HIV in these two groups was examined. Methods: A retrospective record review of 102 miners' audiological records, divided into two groups, was conducted, with data analyzed both qualitatively and quantitatively. Results: Findings suggest that gold miners with a history of tuberculosis treatment have worse hearing thresholds in the high frequencies when compared to those without this history; with evidence of a noise induced hearing loss notch at 6000 Hz in both groups. Pearson's correlations showed values between 0 and 0.3 (0 and −0.3) which are indicative of a weak positive (negative) correlation between HIV and hearing loss, as well as between hearing loss and age in this population. Conclusions: Current findings highlight the importance of strategic hearing conservation programs, including ototoxicity monitoring, and the possible use of oto-protective/chemo-protective agents in this population.


Resumo Introdução: A África do Sul apresenta uma alta prevalência de coinfecção de tuberculose e HIV. Como a ototoxicidade associada aos tratamentos para essas condições é observada na exposição concomitante a outros agentes ototóxicos, como a exposição a ruídos perigosos, é importante investigar o impacto da combinação desses agentes. São poucas as evidências publicadas sobre a co-ocorrência dessas condições nessa população. Objetivo: Comparar a função auditiva de garimpeiros com (grupo tratamento) e sem (grupo sem tratamento) história de tratamento de tuberculose, a fim de determinar que grupo apresentava maior risco de perda auditiva induzida por ruído. Além disso, avaliou-se a possível influência da idade e do HIV nesses dois grupos. Método: Os registros audiológicos de 102 garimpeiros, divididos em dois grupos, foram revisados de forma retrospectiva; os dados foram qualitativa e quantitativamente analisados. Resultados: Os achados indicam os garimpeiros com histórico de tratamento de tuberculose apresentam piores limiares auditivos nas altas frequências quando comparados àqueles sem esse histórico; em ambos os grupos, observou-se perda auditiva induzida por ruído com entalhe audiométrico a 6.000 Hz. As correlações de Pearson mostraram valores entre 0 e 0,3 (0 e -0,3), que são indicativos de uma fraca correlação positiva (negativa) entre o HIV e a perda auditiva, bem como entre a perda auditiva e a idade nessa população. Conclusões: Os resultados atuais destacam a importância de programas estratégicos de conservação auditiva, inclusive monitoramento de ototoxicidade, e o possível uso de agentes oto-/quimioprotetores nessa população.

RESUMO

Abstract Instruction: Noise-induced hearing loss is a leading occupational disease caused by gene-environment interaction. The Grainy Like 2, GRHL2, is a candidate gene. In this regard, many studies have evaluated the association between GRHL2 and noise-induced hearing loss, although the results are ambiguous and conflicting. Objective: The purpose of this study was to identify a precise estimation of the association between rs3735715 polymorphism in GRHL2 gene and susceptibility of noise-induced hearing loss. Methods: A comprehensive search was performed to collect data up to July 8, 2018. Finally, 4 eligible articles were included in this meta-analysis comprising 2410 subjects. The pooled odds ratios with 95% confidence intervals were used to evaluate the strength of the association. Results: Significant association was found in the overall population in the dominant model (GA/AA vs. GG, odds ratio = 0.707, 95% confidence interval = 0.594-0.841) and allele model (G allele vs. A allele, odds ratio = 1.189, 95% confidence interval = 1.062-1.333). When stratified by source of the subjects, we also found association between rs3735715 and noise-induced hearing loss risk in the dominant model (GA/AA vs. GG, odds ratio = 0.634, 95% confidence interval = 0.514-0.783) and allele model (G allele vs. A allele, odds ratio = 1.206, 95% confidence interval = 1.054-1.379). Conclusion: Rs3735715 polymorphism in GRHL2 gene may influence the susceptibility of noise-induced hearing loss. Additional large, well-designed and functional studies are needed to confirm this association in different populations.


Resumo Introdução: Perda auditiva induzida por ruído é uma das principais doenças ocupacionais causadas pela interação gene-ambiente. O Grainy Like 2, ou GRHL2 é um gene que tem sido considerado como candidato. Nesse sentido, muitos estudos avaliaram a associação entre o GRHL2 e perda auditiva induzida por ruído, embora os resultados sejam ambíguos e conflitantes. Objetivo: Identificar uma estimativa precisa da associação entre o polimorfismo rs3735715 no gene GRHL2 e a suscetibilidade à perda auditiva induzida por ruído. Método: Uma pesquisa abrangente foi feita para coletar dados até 8 de julho de 2018. No fim, quatro artigos elegíveis foram incluídos nesta metanálise, abrangeram 2.410 indivíduos. As odds ratios agrupadas com intervalos de confiança de 95% foram usadas para avaliar a força da associação. Resultados: Uma associação significante foi encontrada na população geral no modelo de dominância (GA/AA vs. GG, odds ratio = 0,707, intervalo de confiança 95% = 0,594-0,841) e modelo de alelo (alelo G vs. alelo A; odds ratio = 1,189, intervalo de confiança 95% = 1,062 a 1,333). Quando estratificados pelo local de trabalho dos indivíduos, também encontramos associação entre rs3735715 e risco de perda auditiva induzida por ruído no modelo de dominância (GA/AA vs. GG, odds ratio = 0,634, intervalo de confiança 95% = 0,514 ± 0,783) e modelo de alelo (alelo G vs. alelo A; odds ratio = 1,206, intervalo de confiança 95% = 1,054- 1,379). Conclusão: O polimorfismo Rs3735715 no gene GRHL2 pode influenciar a suscetibilidade à perda auditiva induzida por ruído. Estudos adicionais, amplos, bem desenhados e funcionais são necessários para confirmar essa associação em diferentes populações.
