  1. Model 1: no covariates were adjusted. Model 2: age, race, and education level were adjusted. Model 3: age, race, education level, body mass index, intake of energy, intake of protein, albumin, creatinine, total cholesterol, HDL-cholesterol, LDL-cholesterol, triglyceride, smoking status, alcohol status, hypertension, and diabetes were adjusted. OR odds ratio, 95% CI 95% confidence interval, WWI weight-adjusted-waist index.
