Physical disability predicts stroke incidence in older adults. Impaired physical function, measured by daily living and mobility scales, is a significant risk factor for stroke in the elderly.

Area of Science:

  • Gerontology
  • Epidemiology
  • Neurology

Background:

  • Stroke is a leading cause of disability and death in the elderly population.
  • Identifying predictive factors for stroke is crucial for preventive strategies.

Purpose of the Study:

  • To evaluate physical function as a predictor of stroke incidence.
  • To investigate the association between physical function and stroke in non-institutionalized elderly individuals without prior stroke history.

Main Methods:

  • Prospective longitudinal study of 2,812 individuals aged 65+ in New Haven, CT.
  • Stroke incidence monitored from 1982 to 1988 (167 cases).
  • Physical function assessed using the Katz scale (activities of daily living) and Rosow scale (gross mobility).

Related Experiment Videos

Main Results:

  • Impairment in activities of daily living was independently associated with increased stroke incidence.
  • Reduced gross mobility function was also independently associated with higher stroke incidence.
  • These associations remained significant after controlling for age, sex, diabetes, hypertension, and angina (p < 0.001).

Conclusions:

  • Physical disability emerges as a newly identified risk factor for stroke in the elderly.
  • Physical function assessment can aid in identifying elderly individuals at higher risk of stroke.
  • These findings underscore the importance of maintaining physical function for stroke prevention in older adults.
