Binary logistic regression analysis was performed using the occurrence of sarcopenia as the dependent variable, while the aforementioned variables with P < 0.05, including age, serum albumin, BMI, waist circumference, hip circumference, biceps circumference, handgrip strength, total water content, protein concentration, inorganic salt content, skeletal muscle mass, basal metabolic rate, obesity degree, InBody score, SMI, and body fat content, were included as the independent variables.
