中国中青年男性红细胞压积参考值与地理因素的关系

RELATIONSHIP BETWEEN REFERENCE VALUE OF CHINESE ADULT AND YOUNG MEN HEMATOCRIT AND GEOGRAPHICAL FACTORS

为制定中国中青年男性红细胞压积参考值的统一标准提供科学依据，收集了中国各地用温氏法测定的健康中青年男性红细胞压积参考值，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中青年男性红细胞压积参考值最主要的因素，该参考值随着海拔高度的增高而增大，相关性很显著；用逐步回归分析推导出回归方程，可以由地理因素估算这个地区中青年男性红细胞压积参考值；依据中青年男性红细胞压积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、东北区等六个区．

In order to supply a basis for uniting the reference value standard of Chinese adult and young men hematocrit, a research is made about relationship between the reference value of Chinese healthy adult and young men 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 men hematocrit. As the altitude increases gradually, the reference value of Chinese adult and young men hematocrit also increases gradually, and 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 Chinese adult and young men hematocrit of this area can be reckoned by using regression equation.Furthermore, according to the similarity of the reference value of Chinese adult and young men 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 regions.
