Conclusion vital capacity can be well predicted with the model of height , chest circumference and sitting - height and the model of age mid weight among the children aged 7 - 18 结论由身高、胸围和坐高建立的模型和由年龄、体重建立的模型，可分别准确地推测7 ~ 8岁学生肺活量、肺通气量。
Methods the relations between vital capacity pulmonary ventilation and age , height , body weight chest circumference and sitting height were analyzed with multiple correlation and stepwise regression with spss 方法对大庆市7 ~ 18岁中小学生肺活量、肺通气量与年龄、身高、体重、胸围、坐高进行多元相关及逐步回归分析。
In the multiple regression model vital capacity as dependent variable , height , chest circumference and sitting height were sent into the model , standardized coefficient of the mode was 0 . 903 in boys and 0 . 802 in girls ; pulmonary ventilation as dependent variable , age and body weight were entered as predictors , standardized coefficient of the mode was 0 . 736 in boys and 0 . 748 in girls 以肺活量为应变量，身高、胸围和坐高被引入模型，模型标化相关系数男生为0 . 903 ，女生为0 . 802 ；以肺通气量为应变量，年龄、体重被引入模型，模型标化相关系数男生为0 . 736 ，女生为0 . 748 。
