Main Article Content
Abstract
Objective: The study aimed to describe the prevalence of coal workers’ pneumoconiosis among workers at Vang Danh Coal Joint Stock Company, Quang Ninh in 2021. Methods: a cross-sectional study on 1992 workers exposed directly to coal dust at Vang Danh Coal Joint Stock Company, Quang Ninh in 2021. Results: The prevalence of coal workers’ pneumoconiosis was 15.8%, in which, progressive massive fibrosis was 2.9%, male rate was 16.2%, more than a half (56.6%) of those from 30 to 39 year olds and the work experience from 11 to 15 years was the highest rate. The majority of lesions with small opacity size was p/p (85.1%) and small opacities density in category 1 (60.6%). Conclusion: Most workers did not suffer from coal workers’ pneumoconiosis, most of them were mild.
