Abstract: Objective To figure out the hearing loss awareness rate and hearing situation of type 2 diabetes mellitus (T2DM) patients of the community, and further to investigate application of distortion products otoacoustic emission (DPOAE) in community T2DM patients. Methods From April 2018 to October 2018, 156 T2DM patients aged 20-79 years in the community were enrolled, including 69 males and 87 females, with average age (62.74 ±6.54)years old. All the patients were investigated by questionnaire, pure tone audiometer (PTA), acoustic conduction resistance test, and DPOAE test. Results DPOAE amplitudes of each frequency was lower than the normal amplitudes, amplitudes of the hearing loss group was lower in each frequency than that of no hearing loss group, the difference in 1.5 kHz was statistically significant (P=0.014). Among 312 ears, 98 ears (31.41%) self-report of hearing loss, 242 ears (77.56%) hearing loss at 1.5 kHz on DPOAE examination, (P=0.000). In aged group, 67 ears (29.13%) with self-report of hearing loss and 190 ears (82.61%) hearing loss at 1.5kHz with DPOAE examination(P=0.000). In middle-aged group, 82 ears (37.80%) self-report of hearing loss of patients, and 52 ears (63.41%) at DPOAE 1.5 kHz was hearing loss (P=0.001). In all ears, 216 ears (69.23%) of hearing loss with PTA. Among 214 ears self-report of normal hearing, PTA found that 130 ears (60.75%) was hearing loss (P=0.000). In aged group, 165 ears of hearing loss (71.74%)with PTA(P=0.000). In middle-aged group, PTA suggest 51 ears (62.20%) of hearing loss (P=0.002). Conclusion The detection rate with DPOAE for hearing loss in T2DM patients was higher than that with pure tone audiometer. When middle-aged patients have no conscious of hearing loss, their DPOAE examination has identified the abnormalities. Middle-aged diabetic patients in the community should receive health education of hearing care and hearing screening as early as possible.
