The Relationships Between Physical Performance, Activity Levels, and Falls in Older Men

Area of Science:

• Gerontology
• Epidemiology
• Biomedical Science

Background:

• Physical performance and activity are known risk factors for falls in older adults.
• The combined impact of physical activity and performance on fall risk remains unclear.
• This study investigates the joint association of these factors with incident falls in elderly men.

Purpose of the Study:

• To examine how physical activity and physical performance are jointly associated with incident falls in older men.
• To identify specific patterns of activity and performance that confer the highest fall risk.
• To inform targeted fall prevention strategies for older men.

Main Methods:

• A cohort of 2,741 men (mean age 78.8 years) was studied.
• Physical activity was measured using accelerometry.
• Physical performance was assessed via gait speed, dynamic balance, chair stand test, grip strength, and leg power.
• Falls were recorded through tri-annual questionnaires.

Main Results:

• Men with low activity and low physical performance experienced the highest number and rate of falls.
• A significant portion of falls also occurred in men with low activity/high performance and high activity/high performance.
• Interactions between activity, performance (gait speed, narrow walk), and falls were significant (p = .001–.02), with a secondary peak in fall risk observed in highly active men.

Conclusions:

• While low physical activity and performance significantly increase fall risk in older men, substantial fall risk exists across other combinations of activity and performance levels.
• Integrated assessments of physical activity and performance can enhance the identification of older men at risk of falls.
• Individualized fall prevention strategies tailored to specific activity and performance profiles are recommended.
