Associations calculated using multivariate logistic regression analysis.

OR, odds ratio; CI, confidence interval.

^*Adjusted for age, current smoking status, alcohol drinking status, regular exercise status, and household income quartile.

^†Sarcopenia was defined as low muscle mass percentage (ratio between appendicular skeletal muscle mass and weight), with values ≤29.26% in men.
