摘要
为制定中国青年男性红细胞比容参考值的统一标准提供科学依据,收集了中国200个地区用温氏法(Wintrobe)测定的13818例健康青年男性红细胞比容参考值,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青年男性红细胞比容参考值最主要的因素,在其他地理因素保持不变的情况下,随着海拔高度的逐渐增高,青年男性红细胞比容参考值也在逐渐增大,偏相关性很显著(r=0.445).用主成分分析得到的两个样本主成分作全回归分析,得到一个回归方程Y∧=52.93-1.467z1+6.975z2,将原变量代入,得到回归方程Y∧=58.15+0.002084x1-0.002438x2-0.02399x3-0.4020x4-0.0004443x5,Y∧的95%预测区间为[Y∧-7.52,Y∧+7.52].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青年男性红细胞比容参考值.依据青年男性红细胞比容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 young men's hematocrit, a research is made about relationship between the reference values of 13 818 examples of Chinese healthy young men's hematocrit and five geographical factors in Chinese 200 areas, which are determined by the way of Wintrobe laws. It is found that altitude is the main factors affecting the reference values of Chinese young men's hematocrit.In the condition that other geographical values stay unchangeable while the altitude increases gradually, the reference values of Chinese young men's hematocrit also increase gradually, and the partial correlation is quite obvious (r= 0.445). Applying the method of principal components and regression analysis, one regression equation is given out: Y∧ =58.15+0.002 084x1-0.002 438x2-0.023 99x3-0.402 0x4-0.000 444 3x5.If geographical values are obtained in some areas, the reference values of Chinese young men's hematocrit of this area can be reckoned by using the regression equation. Furthermore, according to the similarity of the reference values of Chinese young men's hematocrit, taking the altitude as the main dividing basis and considering the effects of other geographical factors and population distribution, China can be divided into six regions: Qingzang, Southwest, Northwest, Southeast, North and Northeast region.
