摘要
目的 为制定中国老年男性红细胞压积正常参考值的统一标准提供科学依据。方法 收集中国 2 2 9个单位用温氏法测定的 2 0 0 2 7例健康老年男性红细胞压积正常参考值 ,用曲线回归分析的方法研究了其与海拔高度之间的关系。结果 随着海拔高度的逐渐增大 ,老年男性红细胞压积正常参考值按指数律也在逐渐的增大 ,相关性很显著 (R=0 .90 5) ;推导出了一个曲线回归模型 :Y=44.2× 1 .0 0 0 0 68x± 2 .4。结论 如果知道了中国某地的海拔高度 ,就可以用回归模型估算这个地区的老年男性红细胞压积正常参考值。依据老年男性红细胞压积正常参考值与地理因素的依赖关系把中国分为青藏区、中部区、东部区等三个区。
Objective In order to provide a scientific basis for laying out a unified standard of the reference value of Chinese old men's hematocrit. Methods The reference values of 20027 Chinese healthy old men's hematocrit tested in 229 areas are collected, a research is made about relationship between the reference value of Chinese old men's hematocrit and altitude by using curvilinear regression analysis. Results It is found the reference value of Chinese old men's hematocrit gradually increases by index law, as the altitude gradually increases, the correlation is quite significant (R=0.905). One curvilinear regression model is given out:=44.2×1.000 068 x±2.4. Conclusions If altitude of a particular area is known, the reference value of Chinese old men's hematocrit in this area can be established by using regression model. According to the dependent relationship of Chinese old men's hematocrit to altitude, China can be divided into three districts: Qingzang district, central district, eastern district.
