Abstract
Objective: To analyze the application of Chronic Obstructive Pulmonary Disease (COPD) Screening Questionnaire and pulmonary function test in dust-exposed migrant workers. Methods: In May 2019, 149 cases of dust exposed migrant workers were selected as the research subjects through the free clinic in the countryside. COPD Screening Questionnaire and lung function test were carried out to analyze the high-risk groups and the influencing factors of positive pulmonary function test results. Results: Among 149 cases of dust-exposed migrant workers, 107 (71.8%) were positive for questionnaire screening, 73 (49.0%) were positive for pulmonary function test, 75 (50.3%) were diagnosed with coal worker's pneumoconiosis, and 101 (67.8%) were diagnosed with lung function injury. The positive rate of pulmonary function of migrant workers with positive questionnaire screening results was significantly higher than that of those with negative results (P<0.05) . The results of multivariate analysis showed that compared with non-pneumoconiosis, the risk of positive pulmonary function test results was higher in dust-exposed migrant workers with stage Ⅲ pneumoconiosis (OR=16.462, 95%CI: 3.390-79.946; P<0.01) . Compared with non-smoking, the risks of positive pulmonary function test results of dust-exposed migrant workers with smoking index of 11-20 package years and >20 package years were higher (OR=19.814, 95%CI: 3.854-101.883; OR=9.733, 95%CI: 2.310-41.008; P<0.01) . Conclusion: The risk of COPD in dust-exposed migrant workers is high, so we should strengthen the early examination of the high pneumoconiosis stage and smoking population. The screening questionnaire can better screen out the high-risk groups of COPD, and it can be used as a basic screening tool.
