Ultrasound-assessed abdominal fat distribution and its relation to sarcopenia parameters in community-dwelling young older adults: a cross-sectional study
Ultrasound Evaluation of Abdominal Fat Distribution and Its Association with Sarcopenia Indicators
Overview
This study investigates the relationship between abdominal fat distribution and sarcopenia indicators in older adults. It finds that visceral adipose tissue (VAT) is positively associated with muscle mass indices, while subcutaneous adipose tissue (SAT) shows negative associations with muscle strength and physical performance.
Background
Ageing leads to significant changes in body composition, notably increased abdominal fat and decreased muscle mass, contributing to sarcopenia. Understanding the specific associations between abdominal fat distribution and sarcopenia parameters is crucial. This study aims to clarify these associations using ultrasound to assess abdominal fat distribution.
Data Highlights
Parameter
Association
VAT
Positively associated with muscle mass indices
SAT
Negatively associated with gait speed and relative handgrip strength
Men
VAT positively associated with ASMI, inversely with HGS/BW
Women
SAT negatively associated with HGS/BW and GS
Key Findings
VAT is positively associated with muscle mass indices in both sexes.
SAT is negatively associated with gait speed and relative handgrip strength.
In men, VAT shows a positive association with ASMI and an inverse relationship with HGS/BW.
In women, SAT is negatively associated with HGS/BW and gait speed.
VAT is positively associated with SMI and ASMI in women, while SAT is negatively associated with physical performance.
Clinical Implications
Evaluating abdominal fat distribution using ultrasound may provide insights into sarcopenia parameters in older adults. Clinicians should consider both VAT and SAT when assessing muscle strength and physical performance in this population.
Conclusion
The study emphasizes the need for targeted assessments of abdominal fat distribution in relation to sarcopenia indicators in ageing populations.

An artificial intelligence–based optical coherence tomography pathway met noninferiority criteria for false-positive diabetic macular edema referrals and was associated with fewer referral decisions in a randomized clinical trial.
