目的：为制定中国健康老年前期女性红细胞体积分数的统一标准提供科学依据方法：收集了中国１９１个单位测定的９５５６例健康老年前期女性的红细胞体积分数，用回归分析的方法研究了其与海拔高度的关系结果：发现随着海拔高度的逐渐增大，健康老年前期女性红细胞体积分数也逐渐增大；推导出了一个回归方程＾Ｙ＝４０５＋２３４×１０－３Ｘ结论：如果知道了中国某地的海拔高度，就可以用这个回归方程估算这个地区的健康老年前期女性平均红细胞体积分数 OBJECTIVE: To provide a scientific basis for the establishment of a unified standard for the volume fraction of female red blood cells in healthy pre-senile Chinese.METHODS: The volume fraction of erythrocytes in 9556 healthy pre-senile women collected from 191 Chinese units was collected and analyzed by regression analysis. Height relationship  Results: With the gradual increase of altitude, the volume fraction of red blood cells in healthy pre-senile women also gradually increased; a regression equation was deduced ^ Y = 405 + 234 × 10-3X. Conclusion: Knowing the altitude of a certain place in China, you can use this regression equation to estimate the mean RBC volume fraction of healthy pre-senile women in this area
