Data were indicated as ORs (95% CIs of ORs) which were calculated by multivariate logistic regression models, adjusting for age, affiliation, marital status, position level, smoking status, drinking status, physical activity, mood symptoms, night sleep duration hours, bedtime at night, use of sleeping medicine, sleep quality, and gender as appropriate. ORs, odds ratios; CIs, confidence intervals; WC, waist circumference; TG, triglycerides; HDL-C, high-density lipoprotein cholesterol; BP, blood pressure; FPG, fasting plasma glucose.
