Objectives
To investigate the association between hearing loss, hearing aid use, and cognitive decline.
Design
Prospective population-based study.
Setting
Data gathered from the Personnes Agées QUID study, a cohort study begun in 1989–90.
Participants
Individuals aged 65 and older (N = 3,670).
Measurements
At
baseline, hearing loss was determined using a questionnaire assessing
self-perceived hearing loss; 137 subjects reported major hearing loss,
1,139 reported moderate problems (difficulty following the conversation
when several persons talk at the same time or in a noisy background),
and 2,394 reported no hearing trouble. Cognitive decline was measured
using the Mini-Mental State Examination (MMSE), administered at
follow-up visits over 25 years.
Results
Self-reported hearing loss was significantly associated with lower baseline MMSE score (β = −0.69, P < .001) and greater decline during the 25-year follow-up period (β = −0.04, P
= .01) independent of age, sex, and education. A difference in the rate
of change in MMSE score over the 25-year follow-up was observed between
participants with hearing loss not using hearing aids and controls (β =
−0.06, P < .001). In contrast, subjects with hearing loss using a hearing aid had no difference in cognitive decline (β = 0.07, P = .08) from controls.
Conclusion
Self-reported
hearing loss is associated with accelerated cognitive decline in older
adults; hearing aid use attenuates such decline.
