中国老年人血沉参考值与地理因素的一元回归分析

Univariate regression analysis between reference value of Chinese old people's erythrocyte sedimentation rate (ESR) and geographical factors

为制定中国老年人血沉参考值的统一标准提供科学依据，我们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5项地理因素的关系进行了研究，发现海拔高度是影响老年人血沉参考值最主要的因素，随着海拔高度的逐渐增大，老年人血沉参考值在逐渐的减少，相关性很显著，用回归分析方法推导出10个一元回归方程、可根据中国某地的地理因素，用回归方程估算这个地区的老年人血沉参考值。

In order to supply a basis for uniting the reference value standard of Chinese old people's ESP, aresearch is made about relationship between the reference value of Chinese healthy old people's ESR and fivegeographical factors, which are delermined by means of wintrobe laws. It is found that altitude is the main factoraffecting the reference value of Chinese old people's ESR. As the altitude increase gradually; the reference valueof Chinese old people's ESR decrease gradually, the correlation is'quite obvious Applying the method ofmathematical regression analysis- ten univariate regression equations are givcn out. If geographical index valuesare obtained in some areas, the reference value of Chinese old people's ESR of this area can be reckoned usingregression equation.
