Prevalence of hearing impairment and hearing complaints in older adults: a study in general practice

In one general practice, 660 people aged 60 years or over were screened by means of pure tone audiometry and a specific questionnaire to assess the prevalence of hearing impairment and hearing complaints. Hearing impairment was defined as an average loss of 35 dB or more in the 1, 2 and 4 kHz frequencies in one or both ears. In total, 37.4% (95% CI, 33.3-41.1%) of the participants was hearing impaired. The prevalence was higher in men (55.1%) than in women (44.9%) and clearly increased with age in both sexes. The prevalence of hearing complaints in terms of hearing difficulties and/or tinnitus, was 37.3% (95% CI, 33.6-41.0%), and increased with age, especially in women. Of the subjects with hearing impairment, 64.4% reported hearing complaints. Of the subjects without hearing impairment, 21.1% experienced hearing complaints. This study suggests that screening older adults with relatively simple methods, may identify a large proportion of men and women in general practice with hearing problems. Providing information to both patients and general practitioners about the possibilities of hearing improvement is a crucial step in making people become more aware of hearing problems. This could ultimately lead to improvement of the quality of life of older men and women with hearing problems.
