Abstract

Objectives: A cross-sectional study was carried out in this study to determine some factors related to anthrax at Vang Danh Coal Joint Stock Company, Quang Ninh, in 2021. Method: A cross-sectional survey of all employees at Vang Danh Coal Joint Stock Company, Quang Ninh eligible to participate in the study was conducted from October 2020 to October 31, 2021. Results: The results show that people with working age of more than 5 years but less than 10 years are 2,634 times more likely to have anthrax than those with less than 5 years of seniority (95% CI: 0.293-23,664; χ2=156.715, p. <0.001). There was no difference in the risk of anthrax between men and women (p > 0.05). Compared with workers exposed to cumulative total particulate matter concentrations < 4600 particles, subjects exposed to cumulative total particulate matter concentrations of 4600- 8689 particles had a 14,196 times higher risk of coal dust pneumoconiosis (95 %CI: 2.931- 68.753; p=0.001). Workers exposed to cumulative respiratory particle dust concentrations of 9757 particles were 1,044 times more likely to develop aerosol dust than subjects exposed to cumulative respiratory particulate dust concentrations of <3160 particles (95% CI: 0.306-3.556), but this difference is not statistically significant (p= 0.072>0.05). Conclusions: In this study, there was no difference in the risk of coal dust lung disease between men and women, between smokers and non-smokers. The higher the concentration of cumulative total particulate dust, the grea
