Changes in ventilatory function measurements of United States miners who had participated in two surveys held nine years apart were analysed in relation to smoking habits, dust exposure, and other factors. The results showed trends similar to those reported among British miners. Loss of FEV1 over time and found to be related to smoking (0.1 litre excess decline in current smokers compared with those who had never smoked over 11 years) and to occupational exposure (0.036-0.084 litres over 11 years, depending on the index used). The results offer confirmation of the relationship between work in coal mines and loss in ventilatory function observed in British miners, and also seen in cross sectional studies.
对参加了相隔九年进行的两项调查的美国矿工的通气功能测量变化,就吸烟习惯、粉尘暴露及其他因素进行了分析。结果显示出与英国矿工中所报告的类似趋势。随时间推移第一秒用力呼气容积(FEV1)下降,且发现这与吸烟有关(在11年中,当前吸烟者比从不吸烟者的FEV1额外下降0.1升),也与职业暴露有关(11年中下降0.036 - 0.084升,具体取决于所使用的指标)。这些结果证实了煤矿工作与在英国矿工中观察到的通气功能丧失之间的关系,这在横断面研究中也可见到。
