Examining the association between vestibular function and lower extremity circumference in an aged population

Area of Science:

• Geriatric Medicine
• Human Physiology
• Public Health

Background:

• Vestibular dysfunction affects balance and mobility in older adults.
• Anthropometric measurements are easily obtainable indicators of body composition.
• The relationship between body measurements and vestibular function requires further investigation.

Purpose of the Study:

• To investigate the association between specific anthropometric parameters and vestibular dysfunction.
• To identify potential physical indicators for increased risk of balance problems in the elderly.

Main Methods:

• Analysis of data from 2420 participants in the National Health and Nutrition Examination Survey (1999-2004).
• Vestibular dysfunction assessed using the Romberg test of standing balance.
• Anthropometric measurements included waist, thigh, and calf circumference, as well as waist-to-thigh and waist-to-calf ratios.
• Multivariable logistic regression models were employed for statistical analysis.

Main Results:

• A significant association was found between vestibular dysfunction and calf circumference (OR 0.941), thigh circumference (OR 0.948), waist-to-calf ratio (OR 1.856), and waist-to-thigh ratio (OR 2.516).
• Higher waist circumference and lower thigh and calf circumferences were observed in participants with higher waist-to-thigh and waist-to-calf ratios.
• A dose-response relationship was identified between vestibular dysfunction and these anthropometric ratios.

Conclusions:

• Lower calf and thigh circumference, and higher waist-to-calf and waist-to-thigh ratios, are associated with increased odds of vestibular dysfunction.
• These anthropometric parameters may serve as indicators for identifying individuals at higher risk of balance impairment.
• Findings contribute to understanding the interplay between body composition and vestibular health in older populations.
