中国健康老年人全血比粘度参考值与地理因素的关系

Relationship between reference value of Chinese healthy old people's whole blood contrast viscosity and geographical factors

为制定中国健康老年人全血比粘度参考值的统一标准提供科学依据，收集了中国各地用毛细管法测定的健康老年人全血比粘度参考值，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入全血比粘度参考值最主要的因素，随着海拔高度的逐渐增大，健康老年人全血比粘度参考值也在逐渐的增大，相关性很显著。用逐步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，就可以用这二个回归方程估算这个地区的健康老年人全血比粘度参考值。依据健康老年人全血比粘度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、东北区等六个区。

In order to supply a basis for uniting the reference value standard of Chinese healthy old people's whole blood contrast viscosity, a research is made about relationship between the reference value of Chinese healthy old people's whole blood contrast viscosity and five geographical factors. It is found that altitude is the main factor affecting the reference value of Chinese healthy old people's whole blood contrast viscosity. As the altitude increase gradually, the reference value of Chinese healthy old people's whole blood contrast viscosity also increase gradually, the correlation is quite obvious. Applying the method of mathematical regression analysis, two regression equations are given out. If geographical values are obtained in some area, the reference value of Chinese healthy old people's whole blood contrast viscosity of this area can be reckoned using regression equations. Furthermore, according to the similarity of the reference value of Chinese healthy old people's whole blood contrast viscosity taking the altitude as the main dividing basis and considering effects of other geogrphical factors and population distribution,China can be divided into sir regions: Qingzang, Southwest, Northwest, Southeast, north and Northeast region.
