PURPOSE: To explore the influences of environment factors on the migratory birds patients with chronic obstructive pulmonary disease (MDCOPD).

METHODS: Among the 82 stable MDCOPD from Beijing area in analysis. At Sanya, from October to April the following year (represent wintertime), this study gave COPD assessment test (CAT) scores and medicine research council scale (mMRC) scores respectively, every 2 months follow-up was performed. From May to September (represent summertime), when the MDCOPD patients coming back to Beijing area, this study gave CAT scores and mMRC scores respectively again, every 2 months follow-up was performed. Comparison of the stable MDCOPDs scoring change after changed the living environment. During the follow up period, if the MDCOPDs with acute exacerbation or hospitalization, this study would record it and give the scores after they were coming to stable 1month. At the same time, in the national urban air quality publishing platform record daily air quality index (AQI), record the temperature and relative humidity in the weather network

RESULTS: The scores of CAT in Sanya was significantly lower than Beijing [(20.0±8.0) vs (26.4±7.1) scores, P=0.001]. The scores of mMRC in Sanya was significantly lower than Beijing [(1.9±0.8) vs (2.9±0.9) scores, P=0.001]; according to the latest guidelines, using mMRC evaluation of MDCOPD, its classification had D to C, the CAT scores did not cause the change of classification. Temperature had no obvious change in the wintertime and summertime [(23.1±4.2) vs (24.3±2.3) ℃, P=0.674]; the wintertime of AQI was significantly lower than the summertime of AQI [(49.4±8.9) vs (113.1±14.2) μg/m3, P<0.001]; the wintertime of relative humidity was significantly higher than the summertime of relative humidity [(90.6±4.9)% vs (58.0±10.0)%, P=0.001].

CONCLUSIONS: When the MDCOPDs are coming to the area where have a better air quality and higher relative humidity, it quality of life and activity tolerance can improved obviously.

CLINICAL IMPLICATIONS: air quality and relative humidity affects the quality lift and activity tolerance of patients with COPD, improve air quality and increase humidity, the quality of life and realtive humidity can increased accordingly.
