Abstract |
33 production workers at 3 chemical plants were examined for changes in forced vital capacity (FVC), FEV1 and % of maximal mid-expiratory flow (FEF25-75) resulting from their rotating 3-day, 12h work-shift schedule. An average workshift decrease of 1.1% was observed in % FVC and % FEV1 values and 2.1% in % FEF25-75. Workers on the evening shift (6pm-6am) showed the largest decrease in lung function over the shift. A work week effect was shown in that no recovery in mean % FEV1 and % FEF25-75 was shown by the last working day. Diurnal variation in respiratory function was regarded as being only partly responsible for the observed workshift effect. |
