Occupational and Environmental Risk Factors for Chronic Fibrosing idiopathic Interstitial Pneumonia in South Korea

Abstract

We used conditional logistic regression models to analyze associations with chronic fibrosing IIP adjusted for age, smoking and clinical risk factors. Exposure to stone, sand, or silica significantly increased the risk of chronic fibrosing IIP (odds ratio = 5.01; 95% confidence interval, 1.07-24.21) CONCLUSIONS:: Our findings indicate that exposure to stone, sand, and silica might constitute a risk factor for developing chronic fibrosing IIP in the Korean population.
