An epidemiological survey to determine the prevalence of chronic bronchitis in a mixed mining and non-mining population of Carletonville on the Witwatersrand is described. Eight hundred and twenty-seven men over the age of 35 years were investigated. Chronic bronchitis is shown to significantly more common in miners than in non-miners for every age and smoking category with the exception of the non-smoker no significant difference exists in the prevalence of chronic bronchitis between the mining and non-mining groups. Smoking habits were found to have overwhelming effects on the prevalence of chronic bronchitis in both groups. It is suggested that a synergistic interplay of smoking and general underground aerial pollution (rather than dust inhalation alone) is responsible for the excess prevalence of chronic bronchitis in the miner who smokes.
本文描述了一项流行病学调查,旨在确定威特沃特斯兰德卡尔顿维尔混合采矿与非采矿人群中慢性支气管炎的患病率。对827名35岁以上男性进行了调查。结果显示,除不吸烟者外,在每个年龄和吸烟类别中,矿工患慢性支气管炎的比例均显著高于非矿工。采矿组和非采矿组慢性支气管炎的患病率无显著差异。研究发现,吸烟习惯对两组慢性支气管炎的患病率均有压倒性影响。有人提出,吸烟与一般井下空气污染(而非仅吸入粉尘)的协同相互作用是导致吸烟矿工慢性支气管炎患病率过高的原因。
