Workers in intensive agricultural operations are exposed to dust and endotoxin that are associated with respiratory effects. The authors investigated the longitudinal changes in lung function in male grain farmers. In this study, male grain farmers (n = 263) and male nonfarming control subjects (n = 261) studies initially in 1990/91 were followed-up in 1994/95 and 2003/04. After controlling for potential confounders, grain farmers had an excess annual decline of 9.2 ml/year (95% confidence interval [CI]: 2.7, 15.8, p = .006) in forced vital capacity (FVC) in comparison to control. Long-term exposure to grain dust and other substances in lifetime grain farmers results in progressive loss in lung function.
在密集型农业作业中工作的工人会接触到与呼吸道效应相关的粉尘和内毒素。作者研究了男性谷物种植者肺功能的纵向变化。在这项研究中，1990/91 年最初对男性谷物种植者（n=263）和男性非农业对照者（n=261）进行了研究，随后在 1994/95 年和 2003/04 年进行了随访。在控制了潜在的混杂因素后，与对照组相比，谷物种植者的用力肺活量（FVC）每年过量下降 9.2 毫升/年（95%置信区间[CI]：2.7，15.8，p=0.006）。终身暴露于谷物粉尘和其他物质的长期接触会导致肺功能逐渐丧失。
