3-Years average IQR: PM10, 31.15 μg/m3; PM2.5, 26.14 μg/m3; PM1, 24.12 μg/m3; NO2, 22.42 μg/m3. † Adjusted model includes pollutant, age, sex, tobacco use, physical activity, education, body mass index (BMI), alcohol, place of residence, household income, diabetes history, hypertension history, chronic lung disease history, indoor fuel, fruit and vegetables consumption. PM10: particulate matter with an aerodynamic diameter less than or equal to 10 μm; PM2.5: particulate matter with an aerodynamic diameter less than or equal to 2.5 μm; PM1: particulate matter with an aerodynamic diameter less than or equal to 1 μm; NO2: nitrogen dioxide; CI: confidence interval.
