Abstract:
Objective To analyze the characteristics, trend and influencing factors of occupational pneumoconiosis in Guizhou, and to provide reference for the prevention and treatment of occupational pneumoconiosis. Methods A total of 1 974 mining patients in Guizhou province were selected from 2019-2020 by stratified sampling survey method. According to whether they were accompanied by occupational pneumoconiosis, they were divided into control group (n=1218) and experimental group (n=756) to analyze the morbidity characteristics, changing trend and influencing factors of occupational pneumoconiosis. Results From 2019 to 2020, 756 (38.30%) of the 1974 mining people in Guizhou suffered from occupational pneumoconiosis, including 602 (79.63%) in stage I, 86 (11.38%) in Stage II, and 68 (8.99%) in stage III. The average age was (57.36±6.89) years, and the average length of service was (15.56±4.47) years. The onset age was mainly from 50 to 69 years, and the difference was statistically significant (χ2=8.214，P<0.05). Pneumoconiosis was the main disease in 613 cases (81.08%), followed by silicosis in 85 cases (11.24%), the difference was statistically significant (χ2=25.429，P<0.05). The incidence trend of coal worker's pneumoconiosis was stable, while the incidence of silicosis in 2020 was higher than that in 2019 (χ2=8.797，P<0.05). There was significant difference in smoking status among patients with different stages (χ2=27.212，P<0.05). There were significant differences in age, sex, smoking ratio, length of exposure to dust and complications between the two groups (P<0.05). Logistic regression analysis showed that age, length of dust exposure and complications were independent risk factors for occupational pneumoconiosis (P<0.05). Conclusion The occupational pneumoconiosis in Guizhou area is mainly male, the high incidence age is 50-69 years old, the development is stable, while the incidence of silicosis is increasing in recent years, among which the dust exposure age, age and complications are the high risk factors of occupational pneumoconiosis.
