摘要

Objective: In order to supply a basis for uniting the reference value standard of Chinese presenile women's hematocrit. Methods: A research is made about relationship between the reference value of 17562 examples Chinese healthy presenile women's hematocrit and five geographical factors in Chinese 229 areas, which are determined by the way of Wintrobe laws. Results: It is found that altitude is the main factor affecting the reference value of Chinese presenile women's hematocrit. As the altitude increases gradually， the reference value of Chinese presenile women's hematocrit also increases gradually, and the correlation is quite significant(P=0.000). Applying the method of mathematical factor analysis, one regression equation is given out:Y=49.0+0.00250x1-0.00116x2-0.0861x3-0.00376x4-0.0000160x5±3.8Conclusion: If geographical factors are obtained in some areas, the reference value of Chinese presenile women's hematocrit of this area can be reckoned by using regression equation. Furthermore, according to the similarity of the reference value of Chinese presenile women'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 districts: Qingzang, Southwest, Northwest, Southeast, North and Northeast district.
