  • Model 1: Completely adjusted multiple linear regression model (adjusted for sex, age, BMI, occupation, marital status, education, physical exercise, subjective sleep quality, taking sleep medications).

  • Model 2: U-shaped test regression model (adjusted for sex, age).

  • Model 3: U-shaped test regression model (adjusted for sex, age, BMI).

  • Model 4: U-shaped test regression model (adjusted for sex, age, BMI, occupation, marital status, education, physical exercise, subjective sleep quality, taking sleep medications).

  • Model 5: Multiple linear regression model (adjusted for sex, age).

  • Model 6: Multiple linear regression model (adjusted for sex, age, occupation, marital status, education, physical exercise, subjective sleep quality, taking sleep medications).

  • BMI, body mass index; FG, fasting glucose; HDL-C, high-density lipoprotein cholesterol; TG, triglyceride.
