Abstract:
ObjectivesDetermine associations of hearing loss (HL) and hearing aid (HA) use with cognition, health-related quality of life (HRQoL), and depressive symptoms. Methods: Participants were from the Epidemiology of Hearing Loss Study or Beaver Dam Offspring Study. HL was defined as pure-tone average (.5-4.0 kHz) > 25 dB. A principal component analysis of 5 cognitive tasks measured cognition. The SF-12 measured mental and physical HRQoL. The Centers for Epidemiological Studies Depression Scale measured depressive symptoms (score ≥ 16). Regression models returned beta (B) coefficients or odds ratios (OR) with 95% confidence intervals. Results: This study included 3574 participants. HL (vs. none) was associated with poorer cognition (B-.12 [-.18, -.06]), mental (B-.99 [-1.65, -.33]) and physical (B-.76 [-1.50, -.03]) HRQoL, and increased odds of depressive symptoms (OR 1.49 [1.16, 1.91]). HA users had better cognition than non-users. Discussion: HL likely impacts cognition and well-being. HA use may have cognitive benefits.
