Hearing Loss: Self-Reported Onset and Etiology Among Older Adults in the United States.

This study investigated self-reported age of onset and etiology of hearing loss among older adults in the United States. Study cohort included older adult (≥70 years) survey respondents from the 2017 to 2020 National Health and Nutrition Examination Survey (n = 797). Overall, 51.1% [95% confidence interval [CI]: 46.1-56.1] of older adults self-reported hearing loss. Among older adults who reported hearing loss, the most reported age of onset was age 70 or older (41.7% [95% CI: 38.1%-45.3%]), followed by sequentially younger age brackets including ages 60 to 69 years (27.3% [95% CI: 23.6%-31.3%]) and ages 40 to 59 years (15.7% [95% CI: 12.9%-19.0%]). The most common etiology of hearing loss was aging (66.3% [95% CI: 60.8%-71.4%]) followed by loud long-term noise (30.3% [95% CI: 26.2%-34.9%]) and loud brief noise (13.8% [95% CI: 10.3%-18.4%]). Our study describes the most common age of onset and etiologies of hearing loss among a representative sample of United States older adults.
