This is an observational study into more comprehensive understanding, including the trajectories of lung function decline, inflammatory/immunological mechanisms on pre-COPD or PRISm, clinical outcomes and relevant endotypes on physician-diagnosed COPD. The sponsor will follow up all participants for 1-year period.

This is a multi-center, longitudinal, observational study which includes COPD group with external healthy controls. External healthy controls will be selected from the healthy volunteers enrolled in the asthma translational study (D2287R00186, sponsored by AstraZeneca), whose characteristics match as the entry criteria for Cohort A in the study. Other than participating the procedures of asthma translational study with additional specific activities for COPD, no other activities will be performed in this COPD translational study for Cohort A.
