中年女性红细胞计数正常参考值与地理因素的相关分析

Correlation Analysis on Geographic Factors and the Normal Reference Value of Red Blood Cell Count of Middleaged Women

目的:为制定中国中年女性红细胞计数正常参考值的统一标准提供科学依据.方法:收集了中国331个单位用显微镜计数法测定的41003例中年女性红细胞计数正常参考值,运用相关分析和回归分析的方法,研究了其与八个地理因素的关系.结果:发现中年女性红细胞计数正常参考值与中国地理因素之间有很显著的相关关系(F=364.76,P=0.000).用逐步回归分析的方法推导出了一个回归方程:■=4.184+0.0002421X_1-0.02921X_4+0.0002582X_7+0.08144X_8±0.47.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红细胞计数正常参考值.依据红细胞计数正常参考值与地理因素的依赖关系,把中国分为八个区.

This paper aims at supplying a scientific basis for unifying the normal reference value standard of red blood cell count of Chinese middleaged women.A research is made about relationship between the normal reference value of 41003 examples of Chinese healthy middleaged women＇s red blood cell count and eight geographical factors in 331 areas in China; the normal reference value is determined by the microscopical counting method.It is found that the correlation of geographical factors and the normal reference value of Chinese middleaged women＇s red blood cell count are quite significant（F=364.76,P=0.000）.Applying the method of mathematical regression analysis,one regression equation is inferred：Y^= 4.184＋0.0002421X1-0.02921X4＋0.0002582X7＋0.08144X8±0.47.If geographical values are obtained in some areas,the normal reference value of Chinese middleaged women＇s red blood cell count of this area can be reckoned using the regression equations.Furthermore,according to the similarity of the normal reference value of Chinese middleaged women＇s red blood cell count, China can be divided into eight regions.
