  1. Abbreviations: CESD, Chinese form of Center for Epidemiology Studies Depression scale; CRP, C-reactive protein; SE: standard error.
  2. Underweight: BMI < 18.5 kg/m2; Normal weight: 18.5 ≤ BMI < 25 kg/m2; Overweight: 25 ≤ BMI < 30 kg/m2; Obesity: BMI ≥ 30 kg/m2.
  3. Model 1: adjustment for no covariates.
  4. Model 2: adjustment for age, sex, education, marital status, smoking status, alcohol consumption, baseline CESD-10 score.
  5. Model 3: adjustment for age, sex, education, marital status, smoking status, alcohol consumption, high density lipoprotein, total cholesterol, diabetes, hypertension, suffering chronic pain, baseline CESD-10 score.
