The Association between Daily Walking Behavior and Self-Reported Physical Function in Community-Dwelling Older Adults

Area of Science:

• Gerontology
• Physical Activity and Health
• Biomedical Engineering

Background:

• Many older adults have low participation in organized exercise.
• Daily walking is a primary source of physical activity for this demographic.

Purpose of the Study:

• To examine the relationship between daily walking habits and self-reported physical function in older adults.
• To assess how steps per day and number of walks per day correlate with health-related physical functioning.

Main Methods:

• Utilized activity-registering sensors to objectively measure daily walking behavior in community-dwelling older adults.
• Employed the SF36 10-item Physical Function (PF) subscale for self-reported physical functioning assessment.
• Conducted multiple regression analysis to identify associations between walking metrics and physical function scores.

Main Results:

• Higher daily steps were positively associated with better physical function (p≤.001).
• More frequent daily walks showed a negative association with physical function (p=.010), potentially indicating more indoor ambulation.
• The study included 46 participants with a mean age of 77.6 years.

Conclusions:

• Daily walking volume (steps) is linked to better physical function in older adults.
• While encouraging walking, consider the context (e.g., indoor vs. outdoor) for optimal health benefits.
• Findings support health professionals advising older individuals to integrate walking into their daily routines.
