목적: The purpose of this study is to detect the percentage of hearing loss in patients with diabetes and to evaluate the relationship of age, duration of diabetes and glucose control to hearing loss. 방법:The cross-sectional study involved 160 participants (121 males and 39 females mean age, (55.3 9.01 years) from Erdenet Medical Hospital in 2022. We analyzed serum levels glucose HbA1C% levels.The clinical characteristics of the groups were compared using Independent Samples test. All patients underwent clinical ear examinations and were referred for audiological evaluation. During the patients evaluation process, the RION AA-79 device, which is manufactured in Japan, was tested in both ears at frequencies of 500kHz, 1kHz, 2kHz, 4kHz, and 8kHz. 결과:23.2% of all clients had hearing loss and 76.8% had normal hearing. A higher frequency of hearing loss was present in patients with glycated hemoglobin levels >13%. In the multivariate logistic regression analysis, the most important factors associated with hearing loss were longer diabetes duration, poor glycemic control and age. In the group with HbA1C >13% (n-17), 35.3% had hearing loss while 21.7% of participants had hearing loss in the HbA1C< 13% group (P= 0.002). 결론:Patient age and disease duration had an effect on hearing loss, and it was notable that hearing loss was more pronounced in those with poor glucose control.
