Summary
This summary is machine-generated.

Older adults with hearing disability face a significantly higher risk of injury. Greater hearing loss severity increases this risk, highlighting the need for targeted interventions and support.

Area of Science:

  • Gerontology
  • Public Health
  • Injury Prevention

Background:

  • Population aging is increasing the prevalence of both traumatic injuries and hearing disability in older adults.
  • Hearing disability may heighten injury vulnerability due to impaired balance, reduced environmental awareness, and functional limitations.
  • Longitudinal data on the association between hearing disability and injury risk in older adults is limited.

Purpose of the Study:

  • To investigate the association between hearing disability and the risk of injury among older adults.
  • To utilize a quasi-experimental design with propensity score matching (PSM) for robust analysis.

Main Methods:

  • A population-based cohort study included individuals aged 60+ with and without hearing disabilities (2008-2019).
  • Propensity score matching (1:3 ratio) balanced baseline characteristics between groups.
  • Cox proportional hazard regression models estimated injury admission risk (ICD codes S00-S99).

Main Results:

  • The hearing-disabled group had a higher incidence of injury admissions (14.3%) compared to the nondisabled group (12%).
  • Older adults with hearing disability showed a significantly higher risk of injury admission (HR=1.21, 95% CI 1.14-1.28).
  • The association between hearing disability and injury risk was stronger with greater disability severity and varied by injury site.

Conclusions:

  • Hearing disability is independently linked to increased injury admission risk in older adults.
  • Higher hearing disability severity is associated with a greater risk of injury.
  • Interventions including hearing aids, traffic safety measures, and community support are recommended to reduce injury burden.
