To investigate the relation between pulmonary function and occupational exposure in aluminium pot operators.
2795 observations were obtained in 630 workers over six years of follow up. An autoregressive method of analysis was used.
After adjustment for FEV1 in the three previous years, the effect of smoking v no smoking on FEV1 was -43.1 ml, 95% confidence interval (95% CI) -72.3 to -13.9. Similarly, an increase in the exposure to particulates by 1 mg/m3 corresponded to a decrease in FEV1 of -11.9 ml, 95% CI -19.9 to -3.9. Age was a significant predictor of both FEV1 and FVC.
Exposure to particulates in aluminium potrooms seems to increase the decline in FEV15 thereby increasing the risk of development of chronic obstructive lung disease in pot operators.
研究铝锅生产工人的肺功能与职业暴露之间的关系。
在630名工人中进行了为期六年的随访，共获得2795份观察数据。采用自回归分析方法。
在对前三年的第一秒用力呼气容积（FEV1）进行校正后，吸烟与不吸烟对FEV1的影响为-43.1毫升，95%置信区间（95%CI）为-72.3至-13.9。同样，颗粒物暴露每增加1毫克/立方米，FEV1相应下降-11.9毫升，95%CI为-19.9至-3.9。年龄是FEV1和用力肺活量（FVC）的重要预测因素。
铝锅车间的颗粒物暴露似乎会加速FEV1的下降，从而增加铝锅生产工人患慢性阻塞性肺疾病的风险。
