Objectives:
To clarify the relationship between self-reported hearing loss (HL) and 5-year decline in higher-level functional capacity in high-functioning elderly adults.
Design:
Population-based, prospective cohort study.
Setting:
The Fujiwara-Kyo Study, Nara, Japan.
Participants:
Community-dwelling individuals aged 65 and older with a perfect baseline and valid follow-up instrumental activity of daily living (IADL) (n = 3,267), intellectual activity (IA) (n = 2,925), and social role (SR) (n = 2,698) scores.
Measurements:
Self-reported HL was evaluated using a single question: "Do you feel you have hearing loss?" IADLs, IA, and SR were measured using the Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG-IC) subscales. Geriatric syndromes (depressive symptoms, cognitive impairment, sleep disturbance, falls, urinary incontinence, visual impairment) were self-reported at baseline. Blood tests were performed to measure cardiovascular risk factors.
Results:
During 5-year follow-up, new declines developed for 213 participants in IADLs, 272 in IA, and 327 in SR. After adjustment for all covariates, including geriatric syndromes, using multiple logistic regression analysis, self-reported HL at baseline was associated with a decline in IA (odds ratio (OR) = 1.39, 95% confidence interval (CI) = 1.04-1.86) and SR (OR = 1.34, 95% CI = 1.02-1.76) but not IADLs (OR = 1.07, 95% CI = 0.76-1.48).
Conclusion:
Self-reported HL was found to be a significant predictor of decline in IA and SR. Preventive intervention against age-related HL may contribute to maintaining high-level functional capacity in independent elderly adults.
