Older adults with communication disabilities face a significantly higher mortality risk. This increased risk persists even after accounting for other health and demographic factors, highlighting a critical public health concern.
Area of Science:
- Gerontology
- Public Health
- Epidemiology
Background:
- Communication disabilities (CDs) are prevalent in older adults.
- The independent impact of CDs on mortality risk in this population is not well-established.
Purpose of the Study:
- To determine if older adults with communication disabilities have a higher mortality risk.
- To assess this risk independently of other health and sociodemographic factors.
Main Methods:
- Retrospective cohort study using 2011-2020 National Health and Aging Trends Study data.
- Survival analysis with multivariable Cox proportional hazards regression.
- Included a nationally representative sample of Medicare beneficiaries aged 65+.
Main Results:
- Communication disabilities were associated with a 2.79-fold increased hazard of death.
- After adjustments, older adults with CDs had a 1.46 times higher risk of death compared to those without CDs.
Conclusions:
- Communication disabilities in older adults are independently linked to increased mortality.
- Communication-specific factors may contribute to disparities in mortality outcomes among older adults.
