Abstract: | Objective: To clarify the impact of hearing aids on mental health, social engagement, cognitive function, and physical health outcomes in older adults with hearing impairment. Design: We assessed hearing handicap (hearing handicap inventory for the elderly; HHIE-S), cognition (mini mental state exam, trail making, auditory verbal learning, digit-symbol substitution, verbal fluency, incidence of cognitive impairment), physical health (SF-12 physical component, basic and instrumental activities of daily living, mortality), social engagement (hours per week spent in solitary activities), and mental health (SF-12 mental component) at baseline, five years prior to baseline, and five and 11 years after baseline. Study sample: Community-dwelling older adults with hearing impairment (N = 666) from the epidemiology of hearing loss study cohort. Results: There were no significant differences between hearing-aid users and non-users in cognitive, social engagement, or mental health outcomes at any time point. Aided HHIE-S was significantly better than unaided HHIE-S. At 11 years hearing-aid users had significantly better SF-12 physical health scores (46.2 versus 41.2; p = 0.03). There was no difference in incidence of cognitive impairment or mortality. Conclusion: There was no evidence that hearing aids promote cognitive function, mental health, or social engagement. Hearing aids may reduce hearing handicap and promote better physical health. |
