Sarcopenia was defined as the presence of both low muscle mass and low muscle function. Model 1, adjusted for age, current smoking, alcohol drinking, regular exercise, medical comorbidities, monthly income, and education level. Model 2, adjusted for all variables in model 1 plus depressive symptom. CI, confidence interval; OR, odds ratio.
