Đặc điểm các hình ảnh bất thường trên phim X-quang phổi và một số yếu tố liên quan của người lao động tiếp xúc với bụi silic tại Phú Yên năm 2020

Abstract

Exposure to silica dust increased the risk of pulmonary lesions. This cross-sectional study examined chest X-ray films of 220 workers who were directly exposed to silica dust to describe the characteristics of lesions and identify factors related to having pulmonary lesions. The proportion of workers with small, rounded opacities was 1.8%, and most of them were mild. Of which, small opacities with density 1/1 accounted for the majority with 75.0%, and 100% of the small opacities on X-ray films were p/p size. Workers older than 50 years old were significantly more likely to present with small opacities on X-ray film (p < 0.05). Measures should be taken to prevent the harmful effects of silica dust and ensure the health of workers in Phu Yen.
