Abstract:
OBJECTIVE: To explore the detection of small airway dysfunction in occupational populations and its influencing factors. METHODS: A convenient sampling method was adopted, and 15 490 occupational health workers who were tested for pulmonary ventilation function in 2018 were selected as study subjects. The results of pulmonary ventilation function examination and chest direct digital radiography(DR) were collected and analyzed. RESULTS: Among the study subjects, 2 083 were detected to have abnormal pulmonary ventilation function, the abnormal detection rate was 13.4%; 3 089 subjects were detected to have small airway dysfunction, and the abnormal detection rate was 19.9%. The two-class logistic regression analysis results suggested that female, exposure to organic dusts during work, exposure to asthmogenic during work, chest DR abnormalities and abnormal pulmonary ventilation function were risk factors for abnormal small airway function(P<0.05). CONCLUSION: The abnormal small airway function in occupational populations is related to various factors such as gender and occupational exposure to allergens. The screening of small airway function in this group may help advance the prevention and treatment of respiratory diseases.
