This study is a multicenter cross-sectional study design aimed at screening risk factors for the combination of disease and syndrome in high-risk individuals with chronic obstructive pulmonary disease (COPD).
Targeting high-risk populations for chronic obstructive pulmonary disease (COPD), targeted at key issues such as unclear risk factors and lack of prevention and treatment plans, high-risk population screening was conducted to identify risk factors. This study is expected to detect at least 3600 high-risk individuals with early-stage chronic obstructive pulmonary disease. The incidence rate of high-risk individuals in the early stage of chronic obstructive pulmonary disease is 30%, which means the total screening population is 12000 cases.

Scores for each questionnaire item were tallied based on the participant's responses, and if the total score was ≥2, the participant needed to be seen by a physician for further testing to determine if they had COPD. | During screening |
| COPD Assessment Test (CAT) | 0-40 scores. Scores for each questionnaire item were tallied based on the participant's responses, and if the total score was >10, the participant needed to be seen by a physician for further testing to determine if they had COPD. | During screening |
| COPD screening questionnaire (COPD-Q) | 0-10 scores. Scores for each questionnaire item were tallied based on the participant's responses, and if the total score was ≥4, the participant needed to be seen by a physician for further testing to determine if they had COPD. | During screening |
| chronic obstructive pulmonary disease diagnostic questionnaire (CDQ) | 0-38 scores. Scores for each questionnaire item were tallied based on the participant's responses, and if the total score was ≥17, the participant needed to be seen by a physician for further testing to determine if they had COPD. | During screening |

According to the Diagnosis and Treatment Guidelines for Chronic Obstructive Pulmonary Disease (Revised in 2021), a multi-stage cluster random sampling method was used to select individuals from representative administrative villages with a history of chronic cough or sputum production, breathing difficulties, recurrent lower respiratory tract infections, and/or exposure to potential risk factors for chronic obstructive pulmonary disease.

| Standardised Scale of Physical Fitness in Chinese Medicine | Answer all the questions in the Classification and Determination of Physical Qualities in Chinese Medicine Table. Each question is rated on a 5-point scale, and the raw and transformed scores are calculated to determine the type of physical qualities according to the criteria. Raw score = sum of the scores of each entry. Transformation score = [(raw score - number of entries)/(number of entries × 4)] × 100. | During screening |
| Syndrome therapeutic evaluation scale of chronic obstructive pulmonary disease (COPD-STES) | Subjects should fill in the relevant entries truthfully according to the category of symptoms as judged by the doctor and tick the appropriate box. Among them, the part of tongue and pulse should be filled in by the doctor. | During screening |
