Notes: Quartile-based multiple logistic regression analysis was used to examine the risk of dynapenia and sarcopenia. Adjusted covariates: Model 1= age, health behaviors (smoking, alcohol consumption). Model 2= Model 1+ hypertension, diabetes, stroke, coronary artery disease, physical activity, fat to muscle ratio.

Abbreviations: OR, odds ratio; CI, confidence interval.
