title: [The frequency of hearing impairment in patients with diabetes mellitus type 2].
abstract: OBJECTIVE
  To determine the prevalence of hardness of hearing in patients with diabetes mellitus type 2 and to compare the diabetes characteristics between diabetic patients with and without hardness of hearing.
  
  
  METHODS
  Computerized general practitioners office in Nijverdal, the Netherlands.
  
  
  METHODS
  Descriptive, cross-sectional study.
  
  
  METHODS
  In all patients aged 55 years and over, registered at the general practitioners (n = 1184), diabetes mellitus type 2 and hardness of hearing were determined. Hardness of hearing was defined as use of a hearing aid or an audiometrically determined hearing loss of at least 40db.
  
  
  RESULTS
  A hearing aid was three to four times more prevalent in patients with diabetes mellitus type 2 (n = 86) than in subjects without diabetes of the same age (p < 0.001). Of the diabetic patients 48% had impaired hearing. Patients with hardness of hearing had a longer duration of diabetes than diabetic patients with a normal hearing (10.5 years (SD: 6.9) versus 6.9 years (6.8); p = 0.06, adjusted for age). They suffered less hypertension and had a lower level of glycated haemoglobin.
  
  
  CONCLUSIONS
  Hardness of hearing is frequent in elderly patients with diabetes mellitus type 2. It may be due to diabetic neuropathy.
