OBJECTIVE
Despite the large number of workers in surface sand and gravel mines, there are no previous studies on a cohort of these workers.
METHODS
A cross-sectional study of Michigan surface mine workers included a questionnaire and for those who worked ≥15 years spirometry and chest x-ray.
RESULTS
Questionnaires were completed by 1207 miners, 111 had an X-ray and 70 had spirometry. There were no silicosis cases. There were 117 with asthma, 22 COPD, 129 saw a doctor for shortness of breath (SOB), 125 with possible work-related asthma, and 26 abnormal spirometry results.
CONCLUSIONS
Although, no cases of silicosis were identified, there was more current asthma; and an association of current asthma, COPD and seeing a doctor for SOB with time since first worked, and obstructive changes in some nonsmokers that suggested the potential for adverse respiratory effects.
目的
尽管地表砂石矿工人数量众多，但此前尚无针对这些工人队列的研究。
方法
对密歇根州地表矿工人进行的一项横断面研究包括一份问卷，对于工作≥15年的工人进行肺功能测定和胸部X光检查。
结果
1207名矿工完成了问卷，111人进行了X光检查，70人进行了肺功能测定。未发现矽肺病病例。有117人患哮喘，22人患慢性阻塞性肺疾病（COPD），129人因呼吸急促就医，125人可能患有与工作相关的哮喘，26人肺功能测定结果异常。
结论
尽管未发现矽肺病病例，但当前哮喘病例更多；当前哮喘、COPD以及因呼吸急促就医与首次工作后的时间存在关联，并且一些不吸烟者出现阻塞性改变，提示存在不良呼吸影响的可能性。
