Abstract
Lung function in steelworkers was examined in a longitudinal and cross sectional analysis. The medical records of 1,171 employees were randomly chosen and reviewed for spirometry data as well as for demographic data; in all, the records of 475 steelworkers who had at least three spirometry tests between 1982 and 1991 were studied. The group included 451 white men and 24 black men. A relationship was found between smoking, aging, being overweight, excessive weight gain, and dust exposure with a lower level and a steeper slope of decline of pulmonary function. Forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), and FEV1/FVC% displayed a loss of baseline due to dust exposure of 9.3 milliliters (ml), 6.4ml and 0.1% per year of employment in a dusty area. However, the association between dust exposure and longitudinal decline of lung function was weak. There was a strong relationship between weight gain and longitudinal decline of FEV1 and FVC. A FEV1 decline of 4.7ml per pound per year and a FVC loss of 6.3ml was due to weight gain. The authors suggest that weight gain is an important factor for longitudinal lung function decline.
