The aim of this study was to evaluate hearing function using auditory brainstem response (ABR) in diabetes patients.</span><br> <span style="line-height:14pt"><b><i><span style="color:blue">Methods:</span></i></b> The present case-control study was performed on thirty diabetic patients as a case group and thirty healthy individuals as a control group. Baseline demographic information, HbA1c level, and duration of diabetes were obtained from all diabetic patients. In all subjects, the ABR and pure-tone audiometry (PTA) tests were performed and the results were analyzed using the t-test and logistic regression.</span><br> <span style="line-height:14pt"><b><i><span style="color:blue">Results:</span></i></b> The absolute latency of I was significantly lower in diabetes patients. The absolute latency of III and the interpeak latencies (IPL) I-III were significantly higher in diabetic patients. No significant relationship was noticed in the absolute latency of V and the IPL I-V among diabetic patients in the right and left ears (P>0.05).</span><br> <span style="line-height:14pt"><b><i><span style="color:blue">Conclusion</span></i></b><i><span style="color:blue">:</span></i> The results of this study suggested that diabetes may cause central auditory dysfunction manifested on the absolute latency of III, the IPL I-III and III-V.</span></span></span><br> &nbsp; Hearing loss, Diabetes mellitus, Auditory brainstem response, Interpeak latencies, Pure-tone audiometry 527 534 http://caspjim.com/browse.php?a_code=A-10-2807-1&slc_lang=en&sid=1 Mahbubeh Sheikhzadeh m.sheikhzadeh2@yahoo.com 100319475328460049055 100319475328460049055 No Department of Audiology, School of Rehabilitation Sciences, Babol University of Medical Sciences, Iran Fereshteh Bagheri bagheri.audio@gmail.com 100319475328460049056 100319475328460049056 No Department of Audiology, School of Rehabilitation Sciences, Babol University of Medical Sciences, IR.
