A Comparison of Self-Report and Audiometric Measures of Hearing and Their Associations With Functional Outcomes in Older Adults.

Abstract

The aim was to investigate whether associations of hearing impairment (HI) with functional outcomes in older adults differ when using self-report versus pure-tone audiometry. We examined 1,669 participants ≥70 years in National Health and Examination Survey from 2005-2006 and 2009-2010 whose hearing was assessed by self-report and pure-tone audiometry. We explored functional outcomes associated with audiometric HI (low physical activity, poor physical functioning, and hospitalization). In adjusted models, we found significant associations of audiometric HI with both subjective and objective outcomes (e.g., dichotomous HI with self-reported difficulty in activities of daily living [ADLs], odds ratio [OR] = 1.47, 95% confidence interval [CI] [1.05, 2.06], and low accelerometer-measured physical activity, OR = 2.19, 95% CI [1.11, 4.34]). In contrast, self-reported HI was only associated with subjective outcomes and not with objective outcomes (e.g., dichotomous HI with difficulty in ADLs, OR = 1.63, 95% CI [1.12, 2.38], and low accelerometer-measured physical activity, OR = 0.95, 95% CI [0.66, 1.35]). Results using self-reported hearing should not be considered representative of results using audiometry and may provide distinct aspects of HI in older adults.
