Association Between Metabolic Syndrome and Hearing Impairment: a Study on 200 Subjects.

ABSTRACT

The metabolic syndrome (MS) is a cluster of conditions that occur. togehther, increase risk of heart disease, storke, type 2 diabetes mellitus and hypertension as a possible outcome. The previous research has shown a link between hearing loss and being overweight, diabetic, or suffering from heart disease. However, research on the possible link between hearing loss and metabolic syndrome is limited. Hearing loss due to metabolic syndrome was evaluated in the present investigation. Two hundred individuals with metabolic syndrome were included. All the patients were evaluated on three types of audiometry (pure tone, impedence, and DPOAE).Anthropometric data, blood pressure, blood sugar, and lipid profiles, were all collected from each patient. We also asked about their smoking and drinking habits in the past. SPSS v. 22.0 was used to conduct the statistical analysis. Overall, SNHL affected 58.5% of patients. Patients having moderate hearing loss were the largest demographic group (40%), followed by those with mild hearing loss (15% ). Severe hearing loss only occurred in 3.5% of patients. Hearing loss was shown to be more prevalent in patients with more than three components of metabolic syndrome. Significant associations were found between hearing impairment and metabolic risk factors as waist circumference, fasting blood sugar, serum high-density lipoprotein, serum triglycerides, and systolic and diastolic blood pressure. Hearing loss was only marginally connected to smoking and excessive drinking.
