Crude and odds ratios (ORs), and 95% confidence intervals (95% CI) were calculated by using the complex-sample logistic regression analysis.

Model 1 was adjusted for age.

Model 2 was adjusted for age and waist circumference.

NO, normal body composition; SP, sarcopenic non-obesity; OB, non-sarcopenic obesity; SO, sarcopenic obesity.
