“…Demir et al conducted their study on 456 noise-exposed (≥85 Db) and control unexposed workers to assess the relationship between lipid profile parameters and NIHL occurrence. They found no significant association between lipid profile parameters and NIHL occurrence ( 5 ). Arlien-soborg et al conducted their study to assess the relationship between noise exposure and serum lipid levels.…”

“…NIHL is an irreversible occupational disease and therefore prevention has a critical role in controlling NIHL among industrial workers. Recent studies have reported that changes in some metabolic factors such as serum levels of sugar and lipids might have a role in suffering from NIHL among workers exposed to noise ( 5 , 6 ). Unfortunately, most studies in this field have not provided sufficient evidence to create a causative relationship between lipid profile changes and NIHL occurrence.…”

Background Noise induced hearing loss (NIHL) is an irreversible occupational disease among industrial workers. Recent studies have reported that changes in some metabolic factors such as the serum level of sugar and lipids might have a role in suffering from NIHL among workers exposed to noise. We designed this study to assess the association between lipid profile changes and NIHL occurrence among noise-exposed workers. Methods This case-control study has been conducted according to noise-exposed workers registry data in one of the Iranian automobile factories between 2007 and 2017. We classified study workers into the NIHL and control groups. We assessed the impact of lipid profile parameters across the study groups using the independent samples t-test, chi-square, and regression. Results The mean serum level of cholesterol was significantly higher in the NIHL group than in workers of the control group (215.27 ± 60.30 vs 204.49 ± 63.69 mg/dL; P = 0.041). Moreover, the serum level of HDL was significantly lower in workers in the NIHL group compared with the control group (35.21 ± 6.87 vs 37.43 ± 7.28 mg/dL; P < 0.001). Although other lipid profile parameters (LDL, TG, LDL/HDL ratio) were higher among workers of the NIHL group, their differences were not significant. Conclusion A cholesterol level lower than 200 mg/dL is known as a protective factor and an HDL level lower than 40 mg/dL is an NIHL risk factor. More attention should be paid to controlling serum levels of cholesterol and HDL.

Background/objectivesHearing loss (HL) is associated with certain diseases and affects health, resulting in a low quality of life. Some components of the metabolic syndrome (MetS) coincide with the risk factors for sensorineural hearing loss (SNHL). To date, very few studies have examined the link between MetS and HL. The aim of the current study was to try to understand the potential association between MetS and HL.MethodsUsing Iranian health surveys of professional drivers, we enrolled 11,114 individuals aged 20–60 years, whose main job is to operate a motor vehicle. We examined participants for the presence and absence of SNHL and the components of the MetS. Additionally, we investigated the relationship between MetS and the pure tone air conduction hearing thresholds of participants with SNHL, including low-frequency and high-frequency thresholds.ResultsThis cross-sectional study consisted of 11,114 participants: 3202 (28.81%) diagnosed with MetS and 7911 (71.18%) without and 2772 (24.94%) with SNHL and 8432 (75.86%) without. Participants with SNHL had a higher number of components of MetS (P<0.001 for all components).ConclusionOur results demonstrated that an association possibly exists between different components of MetS (obesity, hypertension, hypertriglyceridemia, high fasting glucose levels, and waist circumference) and SNHL in a population of West Azerbaijan drivers. Therefore, it is important to schedule periodic checkups for drivers to detect and avoid the increase in MetS components at an early stage in this population.

Introduction:The association between hearing impairment and nutritional aspects has received greater attention in research since nutritional factors can cause or potentiate several diseases. Methods to evaluate this variable can be used, enabling the investigation of nutritional health and the adoption of healthy behaviors and diet. Research suggests that higher body mass index (BMI) and waist circumference (WC) are associated with higher hearing thresholds. Objective: to assess the association between anthropometric measurements and hearing loss, based on data from the 2013 Brazilian National Health Survey (PNS). Methods: This is a cross-sectional, analytical study using data from individual interviews with 39,561 individuals from the 2013 PNS. The prevalence of self-reported hearing loss was obtained through the question: "Do you have hearing loss?". BMI and WC were considered exposure variables. The covariates used were: sex, region of Brazil, education level, age group, skin color or race, noise exposure, diabetes, hypertension, high cholesterol, tobacco use, alcohol use, and practice of physical activity. In the multivariate analysis, a hierarchical model was adopted, based on a conceptual theoretical model of factors associated with hearing loss with distal, intermediate, and proximal levels. Univariate and multivariate Logistic Regression models were applied for complex samples. The measure of effect used was the Odds Ratio together with the 95% confidence interval. The significance level adopted was 5%. Results: Prevalence of hearing loss was 2.9%, higher in the age group 75 years or older (15.3%), in males (3.4%), in residents of the South region of Brazil (3.3%), in self-declared white individuals (3.2%), in those with incomplete primary education (7.4%), in overweight (3.2%) and obese (2.9%) individuals, and in individuals at very high risk of developing cardiovascular problems (3.4%). Hearing loss was significantly associated with noise exposure (OR = 1.50 -95%CI: 1.06-2.12), overweight (OR = 1.50 -95%CI: 1.10-2.04), and WC categorized as very high cardiovascular risk (OR = 1.49 -95%CI: 1.14-1.95). In the adjusted analyses, in model 1, hearing loss was significantly associated with overweight (OR=1.57 -95%CI: 1.07-2.30) and obese individuals (OR=1.57 -95%CI: 1.01-2.44). In model 3, the "overweight" category was significantly associated with hearing loss (OR=2.30 -95%CI: 1.25-4.24). Conclusion: Individuals with diabetes, hypertension, and high 13 cholesterol, as well as those exposed to noise, had a higher prevalence of hearing loss. The association between hearing loss and BMI in multivariate analyses was observed in "obese" in model 1 and "overweight" individuals in models 1 and 3.
