There are no recent population-based data on the prevalence of hearing loss in older adults using standard audiometric testing.
The population-based Epidemiology of Hearing Loss Study was designed to measure the prevalence of hearing loss in adults aged 48-92 years, residing in Beaver Dam, Wisconsin.
Hearing thresholds were measured with standardized protocols using pure-tone air-and bone-conduction audiometry in sound-treated booths.
The examination also included an otoscopic evaluation, screening tympanogram, and a questionnaire on hearing-related medical history, noise exposure, other potential risk factors, and self-perceived hearing handicap.
Of the 4,541 eligible people, 3,753 (82.6%) participated in the hearing study (1993-1995).
The average age of participants was 65.8 years, and 57.7% were women.
The prevalence of hearing loss was 45.9%. The odds of hearing loss increased with age (odds ratio (OR)=1.88 for 5 years, 95% confidence interval (Cl) 1.80-1.97) and were greater for men than women (OR=4.42,95% Cl 3.73-5.24).
The male excess of hearing loss remained statistically significant after adjusting for age, education, noise exposure, and occupation (OR=3.65).
These results demonstrate that hearing loss is a very common problem affecting older adults.
Epidemiologic studies are needed to understand the genetic, environmental, and sex-related determinants of age-related hearing loss and to identify potential intervention strategies.
