男性红细胞压积参考值与中国地理因素的关系

Relationship between Reference Value of Chinese Adult Men's Hematocrit and Geographical Factors

为制定中国成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 997个单位用温氏法测定的 951 2 3例健康成年男性红细胞压积参考值 ,运用相关分析和回归分析的方法 ,研究了其与地理因素的关系 .结果发现海拔高度是影响红细胞压积参考值最主要的因素 ,随着海拔高度的逐渐增大 ,红细胞压积参考值也在逐渐增大 ,相关性很显著 (r1 =0 .91 1 ) .用逐步回归分析的方法推导出了一个回归方结论 :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红细胞压积参考值 .依据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

In order to supply a basis for uniting the reference value standard of Chinese adult men's hematocrit, a research is made about relationship between the reference value of 95123 examples Chinese healthy adult men's hematocrit and five geographical factors in Chinese 997 areas,which are determined by the way of wintrobe laws.It is found that altitude is the main factor affecting the reference value of Chinese adult men's hematocrit.As the altitude increases gradually,the reference value of Chinese adult men's hematocrit also increases gradually,and the correlation is quite obvious( r 1=0.911). Applying the method of mathematical regression analysis,two regression equations are given out: =44.6+0.00347 x 1-0.00366x 4 ±5.2. The conclusion is achieved that if geographical values are obtained in some areas, the reference value of Chinese adult men's hematocrit of this area can be reckoned using regression equations. Furthermore, according to the similarity of the reference value of Chinese adult men'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.
