  1. Respiratory function and immunological status in paper-recycling workers.

    Article - En anglais

    The respiratory function and immunological status of workers employed in the paper recycling industry were studied.

    The mean age of the 101 studiea workers was 41 years, and the mean duration of their exposure was 17 years.

    A group of 87 unexposed workers of similar age, duration of employment, and smoking history was studied for the prevalence of chronic respiratory symptoms.

    Lung function in the paper workers was measured by recording maximum expiratory flow volume (MEFV) curves and recording forced vital capacity (FVC), 1-second forced expiratory volume (FEV1), an d maximum expiratory flow rates at 50% and the last 25% of the FVC (FEF50, FEF25).

    Immunological studies were performed in all 101 paper workers and in 37 control workers (volunteers).

    These included skin-prick tests with paper-dust extracts and other nonoccupational allergens, as well as the measurement of total serum immunoglobulin E. Significantly higher prevalences of all chronic respiratory symptoms were found in paper compared with control workers (P<0.01).

    The highest prevalences were found for chronic cough (36.6%), chronic phlegm (34.7%), chronic bronchitis (33.7%), sinusitis (31.7%), and dyspnea (18.8%). Occupational asthma was diagnosed in four (4.0%) of the paper workers.

    A logistic regression analysis performed on chronic respiratory symptoms of paper workers indicated significant effects of smoking and exposure, with the smoking effect being the most important. (...)
