Model 1, no covariates were adjusted; Model 2, age, gender, and race were adjusted; Model 3, gender; age; race; Education level; Marital status; PIR; BMI; Total cholesterol.; Alcohol consumption; smoking; Diabetes; Coronary heart disease and stroke were adjusted. OSA, obstructive sleep apnea; RLS, restless legs syndrome.95% CI, 95% confidence interval; OR, odds ratio; *p < 0.05, **p < 0.01, ***p < 0.001; ap < 0.05 was considered statistically significant.
