一个5年的前瞻性设计，以检验假设，暴露于柴油排放导致慢性呼吸系统的影响，在地下煤矿工人。在5年的研究期间测量呼吸功能的变化和慢性呼吸症状的发展（即，1977-1982年）在美国东部和西部地下煤矿的280名柴油暴露矿工和838名对照矿工中进行。肺功能测定包括1秒用力呼气量（FEV1.0）、用力肺活量（FVC）和50% FVC时的用力呼气流速（FEF 50）。通过问卷调查获得慢性呼吸道症状指标，包括慢性咳嗽、慢性痰和呼吸困难，以及吸烟状况和职业史。根据这些数据，无论是在柴油与非柴油矿工的年龄调整比较中，还是在柴油暴露累积年数的内部分析中，证据模式都不支持这一假设。
A 5-yr prospective design was employed to test the hypothesis that exposure to diesel emissions leads to chronic respiratory effects among underground coal miners. Changes in respiratory function and development of chronic respiratory symptoms were measured during a 5-yr study period (i.e., 1977-1982) in 280 diesel-exposed and 838 control miners from Eastern and Western USA underground coal mines. Spirometry measures of respiratory function included forced expiratory volume in 1 s (FEV1.0), forced vital capacity (FVC), and forced expiratory flow rate at 50% of FVC (FEF50). Chronic respiratory symptom measures, which included chronic cough, chronic phlegm and breathlessness, were obtained by questionnaires, as were smoking status and occupational history. Based upon these data, the pattern of evidence did not support the hypothesis either in an age-adjusted comparison of diesel vs. nondiesel miners or in an internal analysis by cumulative years of diesel exposure.
