Outline
To analyze the risk factors affecting pneumoconiosis stages and the correlation between pneumoconiosis stages and respiratory complications.
The data were collected from pneumoconiosis patients admitted to West China Fourth Hospital of Sichuan University from 2018 to 2022. The risk factors affecting pneumoconiosis stages were studied by a multivariable ordinal logistic regression model, and the association between pneumoconiosis stages and respiratory complications was analyzed using the Cochran-Armitage trend test.
A total of 564 cases were included in the study, including 144 cases (26%) of stage I, 119 cases (21%) of stage II, and 301 cases (53%) of stage III pneumoconiosis. The results of ordinal logistic regression analysis showed that a duration of dust exposure of more than 20 years (OR=2.380, 95% CI: 1.337-4.238) was a risk factor for higher pneumoconiosis stages (P<0.05). Better self-perception (OR=0.232, 95% CI: 0.086-0.624; OR=0.359, 95% CI: 0.140-0.921; OR=0.140, 95% CI: 0.054-0.360), and high body mass index (BMI≥28.0) (OR=0.391, 95% CI: 0.174-0.878) were protective factors for higher pneumoconiosis stages (P<0.05). The detection rate of respiratory complications was 89.72%. The detection rates of pulmonary tuberculosis (Z=5.495), pleural effusion (Z=2.122),pneumothorax (Z=2.710) and emphysema (Z=3.086) increased with the increase of pneumoconiosis stage, while the detection rate of bronchiectasis (Z=-4.472) decreased with the increase of pneumoconiosis stage (P<0.05).
Occupational disease history and psychological status of patients are important factors affecting the development of pneumoconiosis, and the incidence of respiratory complications increases with the increase of pneumoconiosis stages. Therefore, early prevention should be actively implemented, patients’psychological problems should be addressed, attention should be paid to the prevention and treatment of respiratory complications, and the quality of life of patients should be improved.
