We compared the prevalence of respiratory disease in former and current US coal miners using chest radiographs and lung functions collected from 2009 to 2013 among miners of the Appalachian and Interior US coalfields. We calculated prevalence ratios (PRs) of pneumoconiosis and impaired lung function. Significantly higher prevalences of pneumoconiosis (PR = 1.5; 95% confidence interval = 1.2, 2.0) and impaired lung function were observed among former miners compared with active miners. Former miners continue to suffer negative health effects from occupational coal mine dust exposure. The respiratory health of active and former miners is a global concern because international coal production is projected to increase for decades to come.
我们利用2009年至2013年期间从美国阿巴拉契亚和内陆煤田矿工处收集的胸部X光片和肺功能数据,比较了美国前煤矿工人和现煤矿工人的呼吸道疾病患病率。我们计算了尘肺病和肺功能受损的患病率比值(PRs)。与在职矿工相比,在前矿工中观察到尘肺病(PR = 1.5;95%置信区间 = 1.2, 2.0)和肺功能受损的患病率显著更高。前煤矿工人继续因职业性接触煤矿粉尘而遭受负面健康影响。在职和前矿工的呼吸道健康是一个全球关注的问题,因为预计未来几十年国际煤炭产量将增加。
