中国健康中青年女性全血比粘度参考值与地理因素的多元回归分析

MULTIVARIATE REGRESSION ANALYSIS BETWEENREFERENCE VALUE OF CHINESE HEALTHY ADULTAND YOUNG WOMEN WHOLE BLOOD CONTRASTVISCOSITY AND GEOGRAPHICAL FACTORS

为制定中国健康中青年女性全血比粘度参考值的统一标准提供科学依据，收集了中国各地用毛细管法测定的健康中青年女性全血比粘度参考值最主要的因素，随着海拔高度的逐渐增大，健康中青年女性全血比粘度参考值也在逐渐的增大，相关性很显著，用多元回归分析的方法推导出了一个回归方程．如果知道了中国某地的地理因素，就可以用回归方程估算这个地区的健康中青年女性全血比粘度参考值．依据健康中青年女性全血比粘度参考值与地理因素的依赖关系把中国分为青藏区、西南区、西北区、东南区、华北区、东北区等６个区．

In order to supply a basis for uniting the reference value standard of Chinese healthy adult and young women whole blood contrast viscosity, a research is made about relationship between the reference value of Chinese healthy adult and young women whole blood contrast viscosity and five graphical factors. It is found that altitude is the main factor affecting the reference value. As the altitude increases gradually, the reference value increases gradually. The correlation is quite obvious. Applying the method of mathematical regression analysis, one regression equation is given out. If geographical values are obtained in some area, the reference value of this area healthy adult and young women whole blood contrast viscosity can be reckoned by using the regression equation. Furthermore, according to the similarity of the reference value of Chinese healthy adult and young women whole blood contrast viscosity, taking the altitude as the main dividing basis and considering effects of other geographical factors and population distribution, China can be divided into six regions: Qingzang, Southwest, Nothwest, Southeast, North and Northeast regions.
