Multivariable Logistic regression analysis with complex sampling design was performed by adjusting for covariates. OR, odds ratio; 95% CI, 95% confidence interval
a BMI was categorized into underweight (< 18.5 kg/m2), normal weight (18.5–24.9 kg/m2), overweight (25.0–29.9 kg/m2), and obesity (≥30.0 kg/m2)
Model 1 was adjusted for age
Model 2 was adjusted for Model 1 + smoking, alcohol consumption, occupation, education, household income, physical activity, depression, and duration of sleep
