研究美国消防员5年内肺功能的变化。从弗吉尼亚州的662名职业消防员中检查了5年（2009年至2016年）职业体检的肺量测定值。使用第三次全国健康与营养检查调查（NHANES III）数据生成的参考方程估计1秒用力呼气量（FEV 1）、用力肺活量（FVC）和FEV 1/FVC的预测值和预期5年变化。使用配对t检验来确定随时间的显著变化以及观察到的变化和预期变化之间的显著变化。FEV 1和FVC占预计值的百分比分别从100.9± 0.6%下降到92.3 ± 0.5%和99.0 ± 0.6%下降到91.9 ± 0.5%（P<0.001）。 观察到的FEV 1、FVC和FEV 1/FVC的下降是5年内预期下降的2 - 4倍（P <0.001）。 需要加大努力，确保美国消防员的呼吸保护，以尽量减少他们的肺损伤风险。
To examine changes in pulmonary function over a 5-year period in US firefighters. Spirometry values from occupational medical examinations separated by 5 years (2009 to 2016) were examined from 662 career firefighters in Virginia. Predicted values and expected 5-year changes in one-second forced expiratory volume (FEV1), forced vital capacity (FVC), and FEV1/FVC were estimated using reference equations generated from the Third National Health and Nutrition Examination Survey (NHANES III) data. Paired t-tests were used to identify significant changes over time and between the observed and expected changes. FEV1 and FVC (percentage of predicted) decreased (P < 0.001) from 100.9 ± 0.6% to 92.3 ± 0.5% and 99.0 ± 0.6% to 91.9 ± 0.5%, respectfully. The observed decreases in FEV1, FVC, and FEV1/FVC were two to four times greater (P < 0.001) than the expected decrease over 5 years. Increased efforts are needed to ensure respiratory protection for US firefighters to minimize their risk of pulmonary damage.
