Epidemiology and Demographics
Hearing impairment is the third most commonly reported chronic problem affecting the aged population.[1]In one study in the United States, the prevalence of hearing loss (defined by audiometry) increased steadily with age. It is about 11 percent in ages 44 to 54, 25 percent in ages 55 to 64 and 43 percent in ages 65 to 84. The World Health organization (WHO) estimates that in 2025, there will be 1.2 billion people over 60 years of age worldwide, with more than 500 million individuals who will suffer significant impairment from presbycusis. The incidence of presbycusis for people aged 75 years and older is thought to to have risen to 40-50%.
Age
The prevalence of hearing loss increases with age. Presbycusis affects more than half of all adults by age 75 years.
Sex
There is no difference in the prevalence of presbycusis between the sexes.
Race
No known difference exists in the prevalence of presbycusis based on race.
