儿童少年肺活量肺通气量及形态指标相关研究【摘要】目的 了解儿童少年肺活量、肺通气量与 形态发育指标的相互关系，为儿童生长发育研究提供依据。 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。 结果 肺活量与年龄及4项形态指标的相关系数男生为0.81 ～0.93，女生为0.70～0.90；肺通气量与年龄及4项形态指标的相关系数男生为0.64～0.93 ，女生为0.64～0.90。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。 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7～18岁学生肺活量、肺通气量。 【关键词】 肺活量；肺通气；身高；体重；回归分析；学生 【中图分类号】R 179R 195.2【文献标识码】A【文章编号】1000-98 17(2007)06-0521-02 Correlation Analysis Between Vital Capacity, Pulmonary Ventilation and M orphological Parameters Among Children/XIE Jin-xiang. Daqing Center fo r Disease Control and Prevention, Daqing(163311), Heilongjiang Province, China 【Abstract】ObjectiveTo explore the relations between vital capacity, pulmonary ve ntilation and morphological parameters. MethodsThe relationsbetween vital cap acity pulmonary ventilation and age, height, body weight chest circumference andsitting height were analyzed with multiple correlation and stepwise regressionwith SPSS.ResultsThe coefficients of correlation between vit al capacity and age, height,body weight, chest circumference and sitting heightwere 0.81-0.93 in boys and 0.70-0.90 in girls and the coefficients of correlatio n between pulmonar y ventilation and the parameters were 0.64-0.93 in boys and 0.64-0.90 in girls.In the multiple regression model vital capacity as dependent variable, height, c h est circumference and sitting height were sent into the model, standardized coef fic ient of the mode was 0.903 in boys and 0.802 in girls; pulmonary ventilation asdependent variable, age and body weight were entered as predictors,standardizedcoefficient of the mode was 0.736 in boys and 0.748 in girls.Conclusion Vital c apacity can be well predicted with the model of height, chest circumference andsitting-height and the model of age and weight among the children aged 7-18. 【Key words】Vital capacity;Pulmonary ventilation;Body height; Body weight;Regression analysis;Students
