中年男性用力肺活量正常参考值的地理分布规律

为制定中国中年男性用力肺活量正常参考值的统一标准提供科学依据,收集了国内189个单位测定的16461例中年男性用力肺活量正常参考值,应用SPSS统计软件,运用相关分析和回归分析的方法,研究了其与8项地理因素指标的关系。结果发现期间存在很显著的相关关系;用逐步回归分析的方法推导出回归方程,如果知道某地的地理因素,就可以用回归方程计算该地区的中年男性用力肺活量正常参考值。依据中年男性用力肺活量正常参考值与地理因素的依赖关系,把中国分为8个区。

The geographical distribution of the normal reference value of forced vital capacity of middle-aged men

This paper aims at supplying a scientific basis for uniting the normal reference value standard of forced vital capacity of Chinese middle-aged men. A research is made on the relationship between the normal reference value of 16461 examples of forced vital capacity of Chinese healthy middle-aged men and eight geographical factors in 189 areas of China. It is found that the correlation of geographical factors and the normal reference value of forced vital capacity of Chinese middle-aged men is quite significant (F=29.747, P=0.000). By the method of mathematical regression analysis, one regression equation is inferred. If geographical values are obtained in some areas, the normal reference value of forced vital capacity of Chinese middle-aged men 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 middle-aged men, China can be divided into eight regions.
