BACKGROUND
Recent NIOSH publications have focused on the respiratory health of coal miners in central Appalachia, yet 57% of U.S. coal miners work in other regions. We characterized respiratory morbidity in coal miners from these regions.
METHODS
Active coal miners working outside of central Appalachia who received chest radiographs and/or spirometry during 2005-2015 were included. Chest radiographs were classified according to International Labour Office standards and spirometry was interpreted using the American Thoracic Society guidelines. Prevalence of coal workers' pneumoconiosis (CWP) and abnormal spirometry were compared by region.
RESULTS
A total of 103 (2.1%) miners had CWP. The eastern region had the highest prevalence (3.4%), followed by the western (1.7%), and interior (0.8%) regions. A total of 524 (9.3%) miners had abnormal spirometry.
CONCLUSIONS
CWP occurs in all U.S. coal mining regions. Prevalence of CWP was higher in the eastern region, but lower than levels reported in central Appalachia.
背景
美国国家职业安全与健康研究所（NIOSH）近期的出版物聚焦于阿巴拉契亚中部地区煤矿工人的呼吸健康，然而美国57%的煤矿工人在其他地区工作。我们对这些地区煤矿工人的呼吸道发病率进行了特征描述。
方法
纳入2005年至2015年期间在阿巴拉契亚中部以外地区工作且接受了胸部X光检查和/或肺功能测定的在职煤矿工人。胸部X光片根据国际劳工组织标准进行分类，肺功能测定结果依据美国胸科学会指南进行解读。按地区比较煤工尘肺（CWP）患病率和异常肺功能测定结果。
结果
共有103名（2.1%）矿工患有煤工尘肺。东部地区患病率最高（3.4%），其次是西部地区（1.7%）和内陆地区（0.8%）。共有524名（9.3%）矿工肺功能测定结果异常。
结论
美国所有煤矿开采地区均有煤工尘肺发生。东部地区煤工尘肺患病率较高，但低于阿巴拉契亚中部地区报告的水平。
