The objective of the present study was to evaluate the impact of exposure to crystalline silica dust on respiratory function. Methods We included 1428 male participants (aged 40 to 65) recruited from the French general population, at random from electoral rolls, in the cross-sectional ELISABET study and for whom data on forced expiratory flow-volume curve indices z-scores (calculated using the Global Lung Function Initiative 2012 equations) and exposure (via a questionnaire) were available. A cumulative exposure index (CEI) for crystalline silica dust (CEIsilica, expressed in mg.m−3.year) was calculated using the Matgéné occupational exposure matrix. Results 293 of the 1428 participants (20.52%) reported exposure to silica dust. We found that the adjusted z-scores for the forced expiratory volume in the first second/forced vital capacity (FEV1/FVC) ratio decreased significantly as CEIsilica increased. After adjustment, the adjusted z-scores for FEV1/FVC (β: −0.426 (95% confidence interval (CI): −0.792, −0.060) per 1 mg m−3.year increment) and the mean forced expiratory flow between 25 and 75% of the forced vital capacity (FEF25-75) (β: −0.552 (95% CI: −0.947, −0.157)) were significantly lower in the participants with CEIsilica ≥1 mg m−3.year than in non-exposed participants. The likelihoods of having airway obstruction (odds ratio (OR): 3.056 (95% CI: 1.107, 7.626)) or having an impaired FEF25-75 (OR: 4.305 (95% CI: 1.393, 11.79)) were also significantly higher in participants with CEIsilica ≥1 mg m−3.year. Conclusion Our results emphasize the importance of spirometry-based monitoring in workers exposed to more than 1 mg m−3.year of crystalline silica dust, in order to identify small airway obstruction or airway obstruction as early as possible.Show less >
