Abstract
The National Health Interview Survey (NHIS) data on self-reported trouble hearing and the use of hearing aids were examined for the 12 recent surveys from 2007 to 2018 for adults from 18 to 85+ years of age. The aggregate dataset for all years included data from 357,714 adult respondents. Sample size for annual data ranged from 22,058 (2008) to 36,798 (2014). The prevalence of self-reported trouble hearing and hearing aid use, both current use and ever-using hearing aids, are reported for males and females for each age decade. Measures of unmet hearing healthcare (HHC) need were derived from estimates of the prevalence of hearing aid use among those with self-reported trouble hearing. Logistic-regression analyses identified variables affecting the odds of having self-reported trouble hearing, of using or rejecting hearing aids, and of having unmet HHC needs. The results largely corroborate and extend the findings of recent analyses of data from the National Health and Nutrition Examination Survey (NHANES) for a similar period (2011-2020). Overall, for males, 18.5% (95% CI [18.2%-18.8%]) had self-reported trouble hearing and 76.6% [76.0%-77.2%] of these individuals had never used hearing aids and, for females 13.1% [12.9%-13.4%] had trouble hearing and 79.5% [78.9%-80.1%] of these individuals had never used hearing aids. Unmet HHC needs are highly prevalent in the United States and have been so for many years.
