中国中青年男性红细胞压积参考值与海拔高度的曲线模型分析

Curvilinear model analysis between reference value of Chinese adult and young men′s hematocrit and altitude

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 46 2个单位用温氏法测定的 34 383例健康中青年男性红细胞压积参考值 ,用曲线回归分析的方法研究了其与海拔高度之间的关系 .发现随着海拔高度的逐渐增大 ,中青年男性红细胞压积参考值按指数规律也在逐渐的增大 ,相关性很显著 (R =0 .90 3) ;推导出了一个曲线回归模型Y∧ =44.8× 1 .0 0 0 0 6 6 x± 6 .0 .如果知道了中国某地的海拔高度 ,就可用回归模型估算这个地区的中青年男性红细胞压积参考值 .

In order to provide a scientific basis for laying out an unified standard of the reference value of Chinese adult and young men′s hematocrit .Methods:The reference values of 34383 Chinese healthy adult and young men′s hematocrit tested in 462 areas are collected,a research is made about relationship between the reference value of Chinese adult and young men′s hematocrit and altitude by using curvilinear regression analysis.Results:It is found the reference value of Chinese adult and young men′s hematocrit gradually increases by index law,as the altitude gradually increases,the correlation is quite significant ( R = 0. 903) . One curvilinear regression model is given out: Y∧=44.8×1.000 066 x±6. 0 . Conclusion: If altitude of a particular area is known,the reference value of Chinese adult and young men′s hematocrit in this area can be established by using regression model.
