Relationship between sleep characteristics and MetS components. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using logistic regression model for sleep characteristics’ association with hypertension and hyperglycemia. The standardized regression coefficients (β) and 95% CI was estimated using multiple linear regression model for sleep characteristics’ association with WC levels, TG levels and HDL-C levels. The OR and β were adjusted for age, sex, BMI, smoking status, alcohol use status, physical activity and depression. P values were presented with asterisks: *P < 0.05, **P < 0.01
