Values are presented as mean±standard deviation for continuous variables or number (%) for categorical variables.

Diabetes mellitus: fasting blood glucose (>8 h) ≥126 or diagnosis and current usage of drug or insulin injection, High-risk drinking: drinking more than twice a week and at least 7 cups at a time in males and at least 5 cups at a time in females, Hypertension: current usage of antihypertensive drug or ≥140 mmHg systolic blood pressure, or ≥90 mmHg diastolic blood pressure, Dyslipidemia: diagnosis and current usage of drug, or total cholesterol ≥240, or triglyceride ≥200, or high density lipoprotein cholesterol <40, or low-density lipoprotein cholesterol ≥160.

eGFR, estimated glomerular filtration rate; HGS, hand-grip strength; BMI, body mass index.

P-value by independent t-test for continuous variables and by χ2-test for categorical variable.

aP<0.05, bP<0.01.
