Abbreviations:NO2, nitrogen dioxide; HbA1c, glycosylated hemoglobin; HDL, high density lipoprotein; LDL, low density lipoprotein. Note: Model1, adjusted age, sex, educational level (low, medium, high), BMI (<18.5, 18.5–24.9, ≥25), smoking status (current smokers, ex-smoker and non-smoker), pack-years for current smokers, drinking frequency (never, < 1 / month, > 1 / month), energy types for cooking and heating (clean, unclean); Model2, Model1 + O3; Model3, Model1 + PM2.5; Model4, Model1 + O3 + PM2.5. All biomarkers were log transformed in the association analysis.
