Abstract

In Vietnam, pneumoconiosis among coal mine workers is a public health problem due to its irreversibility, high cost of diagnosis, and lack of data related to its prevalence. Therefore, this cross-sectional study was conducted to determine the prevalence of pneumoconiosis in underground coal mining workers in Vang Danh stock joint Company. The crude prevalence of pneumoconiosis was 21.3% and the age-standardized prevalence was 10.3%. The mean age at diagnosis was 18.8 ± 6.93 years. Among the coal worker’s pneumoconiosis (CWP) cases, 75.5% were smokers. The proportion of coal mine worker with pneumoconiosis increased gradually with cumulative dust exposure. The majority of CWP cases (70.8%) were diagnosed in stage I. The most frequently observed parenchymal abnormalities were q/q type (87.5%) and 2.1% CWP cases has been determined to have progressive massive fibrosis (complicated cases). The result of this study contributes to the planning of treatment and prevention of pneumoconiosis for coal mine workers, slowing the progression of the disease.
