Hearing Impairment and Loneliness in Older Adults in the United States.

Hearing impairment impacts fluidity of communication and social interactions and thus may contribute to loneliness. We investigated the cross-sectional association between hearing impairment and loneliness in community-dwelling older U.S. adults using data from the National Social Life, Health, and Aging Project (N = 3,196). Individuals reporting fair/poor hearing had 50% (95% confidence interval [CI] = [1.09-2.05]) higher odds of any loneliness compared with those reporting excellent hearing after adjusting for comorbidity index, functional and cognitive ability, self-reported health, and demographic characteristics. Test for trend suggests a dose-response relationship over levels of hearing impairment. Hearing impairment is highly prevalent and may be an important target for consideration in interventions to reduce loneliness. Further investigation of whether treatment of hearing impairment alleviates loneliness and its disabling effects is also needed.
