  1. Abbreviations: CI Confidence interval, PM Particulate matter with aerodynamic diameter ≤ 1 μm, PM10 Particulate matter with aerodynamic diameter ≤ 10 μm, NO2 Nitrogen dioxide
  2. Modela: Model III unadjusted; Model IV adjusted for age, gender, education; Model V adjusted for those in Model IV, as well as marriage status, the number of chronic diseases, quality of life, BMI index and cognitive function
  3. Model Vb: We utilized the z-score method to standardize the air quality data
  4. βc (95% CI): Logistic regression coefficient (95% CI) estimating the decline in depression scores per point for increase of AQ improvement
  5. Pd-values were calculated using Wald t test
