Abstract:
In order to supply a basis for uniting the reference value standard of Chinese adult and young people's hematocrit,a research is made about relationship between the reference value of Chinese healthy adult and young people'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 adult and young people's hematocrit.As the altitude increases gradually, the reference value of Chinese adult and young people's hematocrit also increases gradually, and the correlation is quite obvious.Applying the method of mathematical regression analysis, two regression equations are given out. If geographical values are obtained in some area, the refbrence value of Chinese adult and young people's hematocrit of this area can be reckoned using regression equations.Furthermore, according to the similarity of the reference value of Chinese adult and young people's hematocrit, 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, Northwest, Southeast, north and Northeast region.
