AimSarcopenia has been associated with a decrease in masseter muscle (MM) thickness in high-risk older populations. However, the relationship to sarcopenia and determinants of MM volume (MMV) in the general older population remain unclear. MabethodIn a cross-sectional study of 1484 older adults of Tokyo, we evaluated MMV using 3D MRI scanning, appendicular skeletal muscle mass (ASMM), handgrip strength, dietary intake, smoking, insulin-like growth factor 1 (IGF-1) levels, and the ACTN3 R577X po...
