Background: Cross-sectional studies consistently suggest that the prevalence of hearing loss is higher in persons with diabetes compared with those without diabetes, especially among younger persons. Hence, the present study was conducted to assess hearing loss in patients of insulin dependent diabetes mellitus.Materials &Methods:A total of 100 patients with presence of insulin dependent diabetes mellitus were enrolled. Complete demographic and clinical details of all the patients were obtained. All the patients belonged to less than 18 years of age. The concentration of hemoglobin A1C (HbA1C) was also documented. In the diabetic cohort, HbA1C levels were measured quarterly, and the average of these measurements was utilized to assess glycemic control. Hearing thresholds were evaluated using pure tone audiometry. Both bone and air conduction thresholds were assessed across frequencies ranging from 250 to 4000 Hz and 250 to 8000 Hz, respectively. The average air conduction thresholds for both ears at each frequency were recorded as the subject's hearing threshold. Hearing loss was classified as a hearing threshold exceeding 25 dB.Results:A total of 100 patients with presence of juvenile insulin dependent DM were evaluated. The mean age of the patients was 15.3 years. Among them 61 patients were boys while the remaining were females. Incidence of hearing loss was 29 percent. While assessing the correlation of occurrence of hearing loss with HbA1c concentration, significant results were obtained. Conclusion:Significant proportion of patients with insulin dependent diabetes mellitusare affected by hearing loss. This correlates significantly with HbA1c levels.
