【摘要】 目的为制定中国中老年人红细胞压积的统一标准提供科学依据。方法收集了中国各地用温氏法测定的健康中老年人红细胞压积，并对其与地理因素的关系进行了研究，用逐步回归分析的方法推导出了２个回归方程。结果发现海拔高度是影响中老年人红细胞压积最主要的因素，随着海拔高度的逐渐增大，中老年人红细胞压积也在逐渐的增大，相关性很显著。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中老年人红细胞压积。结论依据中老年人红细胞压积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、华北区及东北区等６个区。更多还原

【Abstract】 Objective Provide a reference for determining the normal hematocrit value standard of Chinese adult and old people.Methods Chinese healthy adult and old people’s hematocrit value were determined by the way of wintrobe laws and their relationship with five geographical factors were observed.Results Chinese adult and old people’s hematocrit value increased gradually with the increase of altitude,and the correlation is quite obvious.Two regression equations were given out.If geographical values are obtained in some areas, the reference value of Chinese adult and old people’s hematocrit of this area can be reckoned using the regression equations.Conclusion According to the similarity of the reference value of Chinese adult and old people’s hematocrit,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,Southeast,North and Northeast region.更多还原
