Objective:

To assess abdominal fat distribution by ultrasound (US) and explore its association with sarcopenia parameters in community-dwelling older adults aged 60–74 years.

Approach:

Key Findings:

• VAT was positively associated with muscle mass indices across the entire population based on regression analysis.
• SAT was negatively associated with gait speed and relative handgrip strength based on regression analysis.
• In men, VAT was positively associated with appendicular skeletal muscle mass index (ASMI) and inversely associated with relative handgrip strength based on regression analysis.
• In women, SAT was positively associated with ASMI and inversely associated with both relative handgrip strength and gait speed based on regression analysis, while VAT was positively associated with skeletal muscle mass index (SMI) and ASMI based on regression analysis.

Interpretation:

Abdominal fat distribution assessed by ultrasound showed sex-specific associations with sarcopenia parameters.

Limitations:

• The study's cross-sectional design limits causal inferences.
• The sample size may not be representative of the broader population.

Conclusion:

The findings indicate that evaluating abdominal fat distribution is relevant when assessing sarcopenia parameters in aging populations.
