Background: Diabetes mellitus (DM) has been linked to several complications; one of them is hearing impairment which adds on decreasing quality of life of victims.

There is paucity of evidence from Africa. This study determined the magnitude and characteristics of hearing impairment in people with diabetes mellitus at Muhimbili National Hospital, Tanzania’s largest tertiary hospital.

Methods: This was a hospital based descriptive cross sectional study where 390 participants were recruited from June 2014 to January 2015. Data was analyzed using SPSS program version 20.

Results: This study included 390 participants with Diabetes Mellitus, 55.4% were females. The prevalence of hearing impairment was 23.1%, majority being bilateral (16.2%). The commonest type of hearing impairment was sensorineural hearing impairment with prevalence of 20%. Sixteen percent had mild hearing loss, and prevalence decreased as severity of hearing impairment increased. Prevalence of moderately severe and profound hearing impairment was 1.8% and 0.5% respectively. Type 2 DM contributed 68.4% of participants and among this group 26.1% had hearing impairment.

Conclusion: Hearing impairment was found to be prevalent in DM patients with higher prevalence in type 2 DM than in type 1 DM. Bilateral, mild sensorineural hearing impairment is the commonest type and it is more in elderly population. Regular hearing status assessment should be advocated.
