Balance performance and related soft tissue components across three age groups.

Area of Science:

• Gerontology
• Kinesiology
• Women's Health

Background:

• Falls and injuries are significant concerns for aging women, particularly after menopause.
• Declining bone health and balance performance increase fall risk and potential for serious injury.

Purpose of the Study:

• To investigate balance performance and its relationship with body composition in Korean-American women across different menopausal stages.
• Identify factors influencing static and dynamic balance in aging women.

Main Methods:

• Cross-sectional study involving 63 Korean-American women aged 25-65+ years, grouped by age (young, middle, old).
• Dual X-ray absorptiometry used to measure lean mass and fat mass (total body, appendicular, gynoid).
• Assessed static balance, dynamic balance, and physical performance (e.g., sit to stand test).

Main Results:

• Aging correlated with significant changes in lean mass, fat mass, and body mass index.
• Balance and physical performance decreased significantly with advancing age.
• Android/gynoid fat ratio predicted static balance and physical performance; appendicular lean mass predicted dynamic balance.

Conclusions:

• Body composition, specifically lean mass and fat distribution, plays a critical role in maintaining balance in aging women.
• Strategies to preserve lean mass and manage fat accumulation are essential for fall prevention in older women.
