Examination of the Relationship between the Creatinine/cystatin C Ratio and Sarcopenia and Locomotive Syndrome Using the Dual-energy X-ray Absorptiometry Method

Objective: The creatinine/cystatin C (Cre/CysC) ratio is attracting attention as a potential readily available biomarker of the muscle mass. We evaluated the correlation between the Cre/CysC ratio and skeletal muscle mass index (SMI) measured using dual-energy X-ray absorptiometry. We also aimed to investigate the associations of the Cre/CysC ratio with sarcopenia and locomotive syndrome (LS) components.
