Abstract

Objective: To test whether hearing aid use alters cognitive trajectories in older adults.Design, setting, and participants: Data were drawn from the Health and Retirement Study (HRS), a US population-based longitudinal cohort study with cognitive performance measured repeatedly every 2 years over 18 years (1996-2014). This study included 1,586 adults aged 50 and older who who took part in a minimum of three waves of the HRS and who used hearing aids for the first time between Wave 4 and Wave 11.Measurements: Cognitive outcomes were based on episodic memory scores determined by the sum of immediate and delayed recall of 10 words.Results: Hearing aid use was positively associated with episodic memory scores (β=1.24, p<0.001). The decline in episodic memory scores was slower after (β=-0.02, p<0.001) than before using hearing aids (β=-0.1, p<0.001). These results were robust to adjustment for multiple confounders and and to attrition as accounted for with joint model.Conclusions: Hearing aids may have a mitigating impact on trajectories of cognitive decline in later life. Providing hearing aids or other rehabilitative services for hearing impairment much earlier in the course of hearing impairment may stem the worldwide rise of dementia.
