Overview

Prospective cohort study finds greater muscle strength reduces severe fall injuries in older adults, indicating potential prevention strategies.

Key Points

  • To investigate the relationship between muscle strength and risk of severe fall injuries in adults aged 80 and older.
  • Prospective cohort study including 3059 individuals from the HUNT4 survey in Norway.
  • Muscle strength classified as strong, moderately reduced, or reduced using sex-specific reference values.
  • Cox proportional hazards regression analysis assessed associations between strength categories and severe fall injuries.
  • 223 individuals experienced non-fatal (n=196) or fatal (n=27) fall injuries over 3.4 years.
  • Those with strong handgrip and leg strength had lower risks (adjusted HR 0.63, 95% CI 0.43–0.92; HR 0.60, 95% CI 0.43–0.86).
  • Strength associations were more pronounced for women regarding handgrip, while leg strength benefited both sexes.
