中国青年女性血沉参考值与地理因素的多元回归分析

目的 为制定中国青年女性血沉参考值的统一标准提供科学依据，方法 收集中国各地用温氏法测定的青年女性血沉参考值，并对其与地理因素的关系进行了研究。结果 发现海拔高度是影响青年女性血沉参考值最主要的因素，随着海拔高度的逐渐增大，青年女性血沉参考值在逐渐的减小，相关性很显著，用多元回归分析的方法推导了一个回归方程。结论 如果知道了中国某地的地理因素，就可以用这个回归方程估算这个地区的青年女性血沉参考值。

MULTIVARIATE REGRESSION ANALYSIS BETWEEN REFERENCE ERYTHROCYTE SEDIMENTATION RATE VALUE OF CHINESE YOUNG WOMEN AND GEOGRAPHICAL FACTORS

ObjectiveIn order to supply a basis for uniformed reference value standard of Chinese young women erythrocyte sedimentation rate(ESR).MethodsThe relationship of the reference ESR value of Chinese young women and five geographical factors was studied with multivariate regression analysis.ResultsIt was found that altitude was the main factor affecting the reference ESR value of Chinese young women.As the altitude increased gradually,the reference ESR value decreased.The regression equation between the reference ESR value and geographical factors was established with multivariate regression analysis.ConclusionIf geographical index values are obtained in some area,the reference value of Chinese young women ESR of this area can be reckoned using regression equation. Furthermore,according to the similarity of the reference value of Chinese 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,southeast,north and northeast region.
