摘要
目的调查上海地区健康人群的肺功能情况,验证1988年成人肺功能正常预计值公式在现阶段的适用性。方法选取2009年6月至2010年2月的健康体检者,对合格人群进行肺功能测定。根据1988年肺功能正常预计值公式判断结果,以肺功能正常:基本正常为2:1的比例入选360例受试者,年龄19~83岁,平均(42±12)岁,按年龄分为6组,每组60人,男女各半。收集14项肺功能参数:肺活量、功能残气量、肺总量、残气容积、残气容积/肺总量、FVC、FEV,、FEV./FVC、呼气流量峰值、用力呼出25%肺活量时呼气流量(FEF73%)、用力呼出50%肺活量时呼气流量(FEF。)、用力呼出75%肺活量时呼气流量(FEF73%)、D。.CO、每升肺泡容积的一氧化碳弥散量(KCO)。采用多元回归分析,建立新的肺功能正常预计值公式。将受试者数据分别输入上述2种公式,得到2组肺功能参数的预计值,将各参数的实测值和新预计值进行拟合度检验,然后将2组预计值进行相关性分析和差异度比较。结果新肺功能正常预计值公式中各参数的实测值和预计值非常接近,其中肺活量(L)分别为3.6±0.8和3.6±0.8,FVC(L)分别为3.5±0.9和3.5±0.8,FEV,(L)分别为3.0±0.8和3.0±0.7,FEV./FVC(%)分别为83.8±3.1和83.3±2.6,呼气流量峰值(I/s)分别为7.7±1.9和7.5±1.6,FEF25%(L/s)分别为6.8±1.7和6.7±1.2,FEF㈣(L/s)分别为4.0±0.8和3.9±0.7,FEF75%(L/s)分别为1.5±0.7和1.5±0.6,残气容积(L)分别为1.6±0.4和1.6±0.3,功能残气量(L)分别为2.8±0.4和2.9±0.4,肺总量(L)分别为5.0±1.0和5.0±0.9,残气容积/肺总量(%)分别为33.1±4.6和32.7±4.5,DICO(ml·min~·mmHg一,1mmHg=0.133kPa)分别为21.2±5.0和21.2±4.3,KCO(ml·min~·mmHg“)分别为4.4±0.7和4.5±0.4,差异均无统计学意义(t值为一0.856~1.673,均P〉0.05),说明新预计值公式拟合良好。两组的12项肺功能参数(除外D1.CO和KCO)预计值均呈正相关(r值为0.966~0.989,均P〈0.01),差异度均〈5%。结论1988年上海地区成人肺功能正常预计值公式仍适用于现阶段人群。
[Abstract] Objective To collect current information of normal adult pulmonary function in Shanghai, and to verify the applicability of the prediction equations for pulmonary function parameters established in 1988. Methods Subjects who underwent routine physical check-up were initially screened in Zhongshan Hospital from Jun. 2009 to Feb. 2010. Those who met the enrollment criteria were asked to take pulmonary function tests. A total of 240 subjects with normal pulmonary function and 120 subjects with mild small airway abnormalities were enrolled in this study according to the prediction equations established in 1988. The age of these subjects ranged from 19 to 83 years old, with a mean age of (42 + 12) years. All subjects were assigned into 6 groups according to their age, with 60 subjects (30 males, 30 females) in each . Pulmonary function parameters were collected, including VC, FVC, FEVI, FEVj/FVC, PEF, FEgroupF25%, EF50%, FEF75%, RV, FRC, TLC, RV/TLC, DLCO and KCO. New prediction equations for the above 14 parameters were established by multiple regression analysis. The parameters of anthropometry were introduced into the new and the 1988 prediction equations to get 2 groups of prediction values. Comparison ofvariance and correlation analysis between the new and the old prediction values were conducted. Results New prediction equations for normal adult pulmonary function parameters in Shanghai were established. The actually measured parameters were very close to the predicted values: VC (L) 3.6 ±0. 8 vs 3.6 ±0. 8, FVC (L) 3.5 ±0.9 vs 3.5 ±0. 8, FEVI(L) 3.0 +0. 8 vs 3,0 +0.7, FEV1/FVC (%) 83.8±3.1 vs 83.3 ± 2.6, PEF (L/s) 7.7 ±1.9 vsT. 5 ±1.6, FEF25% (L/s) 6.8 +1.7 vs 6.7 ±1.2, FEFs0qo (L/s) 4.0±0.8 vs3.9±0.7, FEF75%(L/s) 1.5+0.7vsl. 5+0.6, RV (L) 1.6+0.4vsl. 6±0.3, FRC (L) 2.8±0.4 vs 2.9 ±0.4, TLC (L) 5.0±1.0 vs 5.0 ±0.9, RV/TLC (%) 33.1 ±4. 6 vs 32.7 ±4.5, DLCO (ml ~ rain-1 .mmHg-1, 1 mm Hg=0.133 kPa) 21.2±5.0vs 21.2±4.3, KCO (ml · min-1 . mm Hg-1) 4.4±0.7vs4.5 ±0.4 (t = -0.856 - 1.673, all P 〉0.05). Except DLCO and KCO, there was a significant positive correlation between each pair of the predicted values ( r = 0. 966 - 0. 989, all P 〈 0. O1 ) , and the variance between each pair of predicted values was within 5% . Conclusion The prediction equations for normal adult pulmonary function parameters established in 1988 is still valid currently for the population in Shanghai.
