摘　　要：目的建立煤矿接尘工人肺通气功能预测值方程,为接尘工人肺通气功能的判定提供依据。方法 2011年3-8月,2994名某矿业集团接尘工人进行职业健康体检,1389人肺通气功能测试结果正常。从肺通气功能正常者中选取1139人用于建立线性预测值方程,250人用于预测值方程的回代检验。结果年龄与FVC、FEV1、FEV1%、MMF和PEFR均呈负相关(P<0.05),身高与FEV1%呈负相关,与其他指标呈正相关,体重与MMF呈负相关,与FVC、PEFR呈正相关(P<0.05)。以年龄、身高、体重为自变量,肺通气功能各指标为因变量建立预测值回归方程,将预测值回归方程经原始资料、回代资料进行回代检验,符合率均大于90%,且原始资料与回代资料的肺通气功能指标差异无显著性(P>0.05)。应用建立的预测值方程得出的预测值比固化在仪器内的预测值低,差别有统计学意义(P<0.05)。结论通过建立的5项肺通气功能指标的预测值方程得出的正常预测值较固化仪器中的预测值效果好。Objective To establish the predictive value of pulmonary ventilation function for dust-exposed-workers in some coal mine. Methods From March to August in 2011, 2994 coal workers were involved in the research, their pulmonary ventilation function were examined by pulmonary function measuring instrument. 1389 worker＇s pulmonary ventilation function were normal, the data of 1139 workers established the predictive value equation, and those of 250 workers tested the equation. Results Age was negatively correlated with FVC, FEV1, FEV1%, MMF and PEFR （P 〈0. 05）. Height was negatively correlated with FEV1% , however, it was positively eorrelated with others （ P 〈 0. 05 ）. Weight was negatively eorrelated with MMF and positively eorrelated with FVC and PEFR （P 〈 0. 05）. The regression equation of the predictive value was established by age, height and weight as in dependent variables. It were above 90% that the aeeordanee ratio to test the equation by original data and test data. Predictive value of pulmonary ventilatory function from predictive value equation were lower than that of lung fucntion machine （P 〈 0. 05 ）. Conclusion Predictive value of pulmonary ventilatory function from predictive value equation was superior to that of lung fucntion machine.
