Analysis of screening questionnaire on chronic obstructive pulmonary disease and pulmonary function test on dust-exposed migrant workers

Abstract

Objective. To analyze the application of screening questionnaire on chronic obstructive pulmonary disease (COPD) and pulmonary function test on dust-exposed migrant workers.

Methods. According to 149 eligible objects of study selected in medical outreach, the real situation on them threaten by COPD and influential elements are analyzed in depth.

Results. 73 workers are suspected to be suffered COPD by pulmonary function test. Th e detection rate (62.6%)of suspected COPD in the population with total score of more than 5 is significantly higher than that of the population with total score of less than 5 (14.3%). Th e result has the statistical significance (X2=28.19, p<0.000). Age, working years, stage of pneumoconiosis, smoking or not, smoking index are all the factors influencing the positive results of pulmonary function tests, and pneumoconiosis stage is the biggest influencing one.

Conclusion. By using questionnaires and pulmonary function tests, the early diagnosis and intervention of COPD are available.
