3D Body Scanning-Derived Normative Values of Appendicular Circumferences: A Novel Tool for Sarcopenia Screening in Chinese Adults.

ABSTRACT:

Background

Appendicular circumferences (ACs) are critical predictors of skeletal health, cardiovascular disease risk and mortality. Currently, comprehensive reference values and associated factors for thigh (TC), calf (CC), upper arm (UAC) and forearm (FC) circumferences remain unestablished in Chinese adults.

Methods

This community-based cross-sectional study (China National Health Survey, April 2023-November 2024) enrolled 8915 adults (≥20 years) for reference value development and 10 632 for association analysis. ACs were measured via 3D scanning, body composition via bioelectrical impedance analysis and handgrip strength using a Jamar dynamometer. Sex-specific centile curves (P2.5-P97.5) were generated using lambda-mu-sigma methods. Propensity score matching balanced age
