摘要
目的:为制定中围青春期男性用力肺活量(FVC)正常参考值的统一标准提供科学依据.方法:收集了中国70个单位测定的6071例青春期男件FVC正常参考值,应用SPSS统计软件,运用相关分析和回归分析的方法,研究其与8项地理因素指标的关系.结果:发现青春期男性FVC正常参考值与中国地理因素之间有很显著的相关关系(F=10.636,P=0.000).用逐步回归分析的方法推导出了1个回归方程:Y=2.501+0.009689X_2-0.4050X_3+0.1393X_4-0.02982X_5-0.001257X_7±0.660.在该的回归方程中,Y是青春期男性FVC正常参考值(L),X_2是年日照时数(h),X_3是年日照百分率(%),X_4是年平均气温(℃),X_5是气温年较差(℃),X_7是年降水量(mm);0.660是剩余标准差的值.结论:如果知道了中国某地的地理因素,就可以用回归方程计算这个地区的青春期男性FVC正常参考值.依据青春期男性FVC正常参考值与地理因素的依赖关系,把中国分为8个区.
Abstract
AIM: To supply a scientific basis for uniting the normal reference value standard of forced vital capacity of Chinese adolescent boys. METHODS: A research is made about the rela tionship between the normal reference value of 6071 examples of forced vital capacity of Chinese healthy adolescent boys and eight geographical factors in 70 areas in China. RESULTS: It is found that the correlation of geographical factors and the normal reference value of forced vital capacity of Chinese adolescent boys are quite significant ( F = 10. 636, P = 0.000). Applying the method of mathematical regression analysis, one regression equation isinferred: Y = 2.501 + 0. 0O9689X_2 - 0.4050X_3 + 0. 1393X_4 -0.02982X_5 -0. 001257X_7 ±0.660. In the above equation, Y is the normal reference value of forced vital capacity of adolescent boys( L) ; X_2 is the annual sunshine duration( h) ; X_3 is the annu al percentage of sunshine duration ( % ) ; X_4 is the annual mean air temperature (t ) ; X_5 is the annual range of air temperature (℃ ) ; X_7 is the annual precipitation amount( mm) ; 0. 660 is the value of the residual standard deviations. CONCLUSION : If geographical values are obtained in some areas, the normal reference value of forced vital capacity of Chinese adolescent boys of this area can be reckoned by using the regression equations. Furthermore, according to the similarity of the normal reference value of forced vital capacity of Chinese adolescent boys, China can be divided into eight regions.
