中国健康老年人血沉参考值(温氏法)与地理因素的多元回归分析

Multivariate Regression Analysis between ReferenceValue (Wintrobe) of Chinese Healthy Old People′sErythrocyte Sedimentation Rate (ESR)and Geographical Factors

为制定中国健康老年人血沉参考值（温氏法）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老年人血沉参考值，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健康老年人血沉参考值（温氏法）最主要的因素，随着海拔高度的逐渐增大，健康老年人血沉参考值（温氏法）在逐渐的减小，相关性很显著．用多元回归分析的方法推导出了二个回归方程．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健康老年人血沉参考值（温氏法），依据健康老年人血沉参考值（温氏法）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 oder to supply a basis for uniting the reference value (wintrobe) standard of Chinese healthy old people′s ESR,a research is made about relationship between the reference value (wintrobe) of Chinese old people′s ESR 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 (wintrobe) of Chinese healthy old people′s ESR.As the altitude increase gradually,the reference value (wintrobe) of Chinese healthy old people′s ESR decrease gradually,the correlation is quite obvious.Applying the method of mathematical regression analysis ,two regression equations are given out.If geographical index values are obtained in some area the reference value (wintrobe) of Chinese healthy old people′s ESR of this area can be reckoned using regression equations.Furthermore according to the similarity of the reference value (wintrobe) of Chinese healthy old people′s ESR,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,Southease,north and Northease region.
