IMPACT COPD Cohort (China)

Chronic obstructive pulmonary disease (COPD) is a major chronic respiratory condition with high prevalence of multimorbidity. COPD and comorbidities interact dynamically, contributing to symptom fluctuation, acute exacerbations, hospitalization, and long-term disease progression. The IMPACT COPD Cohort (China) is a multicenter prospective observational cohort designed to establish a real-world evidence base for integrative Chinese-Western medicine management of COPD with comorbidities. The cohort integrates conventional clinical assessments (symptoms, questionnaires, spirometry, imaging, and biomarkers) with continuous multisensor digital monitoring (e.g., heart rate, blood pressure, activity, sleep patterns, and other physiological and behavioral measures) and digital Traditional Chinese Medicine (TCM) phenotyping (e.g., tongue, pulse, and facial diagnostics). The study aims to characterize risk profiles of high-risk populations and patients with confirmed comorbidities, develop and validate prediction models for comorbidity risk and acute exacerbation events, and support evidence generation for long-term management strategies with early screening and risk warning capabilities across hospital, community, and home settings.

Chinese Population Health and Multimorbidity Study

The Chinese Population Health and Multimorbidity Study (CPHMS; initially named China Pulmonary Health Study, CPHS) was a large-scale epidemiological survey designed to investigate the pulmonary health of Chinese adults aged 20 years or older leveraging a multistage stratified sampling scheme between 2011 and 2014 in mainland China. Briefly, a total number of 57,779 local residents were recruited from 10 representative provinces and municipalities and were invited to participate in the study. A final number of 50,991 adults who met the major inclusion criteria could be considered in further analyses. In order to investigate the changes of pulmonary health and disease status (e.g. occurrence and development of chronic respiratory diseases and other important relevant multimorbidities, lung function indices, etc.) and corresponding impact factors in the CPHMS study population, we plan to initiate the first round of follow-up investigation between 2025 and 2027 (planned) , i.e. more than 10 years after the baseline survey.
