Title Non-malignant asbestos-related diseases in Brazilian asbestos-cement workers
Bibliographic information Sep. 2001, Vol.40, No.3, p.240-254. Illus. 69 ref.
Abstract 828 former asbestos-cement workers enrolled in a cross-sectional and cohort study of respiratory morbidity were submitted to a detailed occupational history, respiratory symptoms questionnaire, spirometry, chest x-ray, and high resolution computed chest tomography (HRCT). Asbestosis and pleural thickening were assessed according to HRCT criteria. Asbestosis was present in 74 (8.9%) and pleural thickening in 246 (29.7%) cases. Latency time from first exposure was the best predictor for both asbestosis and pleural thickening. Subjects in the higher exposure groups presented lower levels of lung function. Obstructive defects were significantly related to smoking, shortness of breath, body mass index, and age, whereas restrictive defects were related to asbestosis, shortness of breath, and latency time. Chronic bronchitis increased with latency time in the three smoking groups and was significantly related to pleural thickening (OR 1.56). Shortness of breath was significantly associated with body mass index and pleural thickening (OR 1.30).
