Title The burden of silicosis, pulmonary tuberculosis and COPD among former Basotho goldminers
Bibliographic information Sep. 2008, Vol.51, No.9, p.640-647. Illus. 25 ref.
Abstract The burden of silicosis, pulmonary tuberculosis and COPD is described in 624 South African gold miners 18 months after cessation of work. Questionnaires were administered, and spirometry, chest radiography, tuberculosis investigations and urine HIV antibody assays were performed. The mean age of subjects was 49.4 years and their mean employment duration 25.6 years. Most subjects had had jobs with medium (26.5%) or high (65.4%) dust exposure. Current smoking rate was 35%, with ever smoking 61%. HIV antibodies were detected in the urine in 22.3%. Prevalences were: silicosis 24.6%, past tuberculosis 26%, current tuberculosis 6.2%, airflow obstruction 13.4% and chronic productive cough 17.7%. Almost 50% of these miners had at least one of these respiratory conditions.
