男性青年红细胞压积参考值与地理因素的分析

Multivariate Regression Analysis between Reference Value of Chinese Young Men′s Hematocrit and Geographical Factors

为制定中国男性青年红细胞压积参考值的统一标准提供科学依据，收集了全国各地用温氏法测定的健康男性青年红细胞压积参考值，并对其与地理因素的关系进行了研究，发现海拔高度是影响男性青年红细胞压积参考值最主要的因素．随着海拔高度的逐渐增大，男性青年红细胞压积参考值也在逐渐地增大，相关性很显著．

In order to supply a basis for uniting the reference value standard of Chinese young men′s hematocrit,a research is made about relationship between the reference value of Chinese healthy young men′s hematocrit and five geographical factors,which are determined by the way of Wintrobe lows.It is found that altitude is the main factor affecting the reference value of Chinese young men′s hematocrit.As the altitude increases gradually,the reference value of Chinese young men′s hematocrit also increases gradually,and the correlation is quite obvious.Applying the method of mathematical regression analysis,one regression equation is given out.
