“…However, in spite of these pathological findings in the inner ear, an evaluation of the existing literature showed that the relationship between diabetes and hearing loss is still controversial. While some studies revealed an increased risk of hearing loss in diabetes patients, other studies did not find any differences in hearing loss between controls and diabetes patients [6,[10][11][12][13][14][15][16][17][18][19][20].…”

OBJECTIVE:Considering that both hearing loss and Type 2 diabetes (DM2) are significant health issues, it is worthwhile to examine the relationship between the two. After evaluating the existing literature, it was evident that there have not been sufficient prospective studies about hearing loss and DM2 that include elderly participants. Therefore, the aim of this study was to focus on and evaluate the interaction between DM2 and hearing loss in an elderly population. MATERIALS and METHODS:The current study included 93 DM2 subjects, 65-89 years of age, as well as a control Group of 90 non-diabetic subjects, aged 65-85 years of aged, who were matched to the DM2 subjects by age and sex. RESULTS:The current investigation produced five major findings. The diabetics had higher thresholds for all frequencies, except 0.25 kHz, compared to the controls. Although there were significant differences at low frequencies, such as 0.5 and 1 kHz, the differences were most pronounced at 2, 4, and 8 kHz. The thresholds for speech reception were significantly higher in the diabetics than in the controls. Also, there were no side differences between the right and left ears in the diabetics or the controls, and the diabetics had lower speech discrimination scores than the controls. CONCLUSION:Diabetes is a complex, systemic disease that can affect multiple organs and physiological functions, on molecular and biochemical levels. The current investigation showed that elderly DM2 subjects had poorer hearing levels when compared with age and sex matched non-DM2 subjects.

“…Erdem et al (2003) noted that the nature of the hearing loss associated with T2DM was still controversial, and found mixed results comparing emissions amplitude in type II diabetics with controls. Other studies utilizing limited hearing measures and/or small numbers of subjects have revealed no differences in hearing loss for type II diabetics and their offspring relative to controls (Malpas et al, 1989;Ma et al, 1998;Ologe et al, 2005).…”

Characterization of hearing loss in aged type II diabetics

Presbycusis - age-related hearing loss - is the number one communicative disorder and a significant chronic medical condition of the aged. Little is known about how type II diabetes, another prevalent age-related medical condition, and presbycusis interact. The present investigation aimed to comprehensively characterize the nature of hearing impairment in aged type II diabetics. Hearing tests measuring both peripheral (cochlea) and central (brainstem and cortex) auditory processing were utilized. The majority of differences between the hearing abilities of the aged diabetics and their age-matched controls were found in measures of inner ear function. For example, large differences were found in pure-tone audiograms, wideband noise and speech reception thresholds, and otoacoustic emissions. The greatest deficits tended to be at low frequencies. In addition, there was a strong tendency for diabetes to affect the right ear more than the left. One possible interpretation is that as one develops presbycusis, the right ear advantage is lost, and this decline is accelerated by diabetes. In contrast, auditory processing tests that measure both peripheral and central processing showed fewer declines between the elderly diabetics and the control group. Consequences of elevated blood sugar levels as possible underlying physiological mechanisms for the hearing loss are discussed.

“…Previous studies investigating hearing thresholds in DM, in Nigeria7–9 and elsewhere,10–16 have been dominated by descriptive cross-sectional surveys, often with widely variable results. The reported prevalence of hearing loss ranges from 0.0% to 90.0%.…”

ObjectivesTo determine the prevalence, types and severity of hearing loss and associated factors in a hospital population of adult Nigerians with diabetes mellitus.Subjects and methodsThis study was a prospective hospital-based study conducted at the Otorhinolaryngology and Diabetic Clinics of the University of Nigeria Teaching Hospital (UNTH) Ituku-Ozalla, Enugu, for a period of 12 months. Consecutively presenting eligible adult diabetics and their age- and sex-matched healthy controls were recruited. Each case and control participant had clinical and otologic examination, followed by pure tone audiometry. Data were analyzed using descriptive and comparative statistics.ResultsThere were 224 patients and 192 control participants. The patients comprised 112 males and 112 females (sex ratio=1:1), whose mean age was 47.6 years (range: 26–80 years). The prevalence of hearing loss was 46.9%. This comprised 43.8% sensorineural and 3.1% conductive hearing losses. The distribution of hearing loss by severity was mild 25.0%, moderate 15.6% and severe 6.3%. The controls comprised 96 males and 96 females whose mean age was 44.6 years (range: 25–79 years). The prevalence of hearing loss was significantly higher overall and by type (sensorineural hearing loss, conductive hearing loss) in cases compared with controls.ConclusionThe prevalence of hearing loss among diabetic adults at UNTH, Enugu, is comparatively high. Hearing loss is predominantly sensorineural and often mild to moderate in severity. Routine audiometric evaluation of all adult diabetics at UNTH is recommended.
