For each exposure variable, we fitted mixed linear models for PCS and MCS, accounted for centre effect and repeated data, and adjusted for age, gender, BMI, smoking, occupation, and chronic diseases. Interaction terms between exposures and asthma and/or rhinitis status were further added.Results: 48% were men and the mean(SD) age of the ECRHSII and III participants were 43(7) and 54(7) years. Mean(SD) PCS and MCS were 49(10) and 50(11) at ECRHSII, and 47(11) and 51(10) at ECRHSIII. MCS was inversely associated with NO2, PM2.5 and PM10, and positively associated with NDVI (regression coefficients (95%CI) for one IQR change in exposure were -0.70 (-1.17; -0.23), -1.84 (-2.83; -0.85), -1.80 (-2.89; -0.71) and 0.91 (0.34; 1.48), respectively). No association was found for PCS. Similar association patterns were observed for each asthma-rhinitis phenotype.Conclusion: Higher long-term air pollution exposure and lower greenness were associated with higher MCS but not PCS, regardless of asthma-rhinitis status.FootnotesCite this article as: European Respiratory Journal 2021; 58: Suppl. 65, OA100.This abstract was presented at the 2021 ERS International Congress, in session “Prediction of exacerbations in patients with COPD”.This is an ERS International Congress abstract.
