Variations in Postmenopausal Body Composition: A Cross-Sectional Comparison between Physical Activity Practitioners...

Area of Science:

• Gerontology
• Exercise Physiology
• Women's Health

Background:

• Physical activity is linked to weight management and health.
• Limited research exists on physical activity's effects on postmenopausal women's body composition.
• Menopause involves physiological changes impacting health and body composition.

Purpose of the Study:

• To investigate the association between physical activity levels and body composition in postmenopausal women.
• To identify specific body composition metrics influenced by physical activity in this demographic.

Main Methods:

• Cross-sectional and retrospective study design.
• Inclusion of 702 women.
• Data collection via anthropometric measurements and Dual-Energy X-ray Absorptiometry (DEXA).

Main Results:

• Many participants were overweight/obese with high waist circumference (WC), indicating disease risk.
• Physical activity did not significantly reduce most body composition metrics in postmenopausal women.
• Inactive postmenopausal women showed 1.18 times higher risk for very high disease risk based on WC.

Conclusions:

• Physical activity alone may not be sufficient to significantly alter body composition in postmenopausal women.
• Inactive postmenopausal women face a substantially elevated risk of disease, particularly related to central obesity.
• Further research is needed to optimize physical activity interventions for this population.
