指数曲线在高血压年龄患病率分析中的应用

THE APPLICATION OF THE INDEX CURVE TO THE ANALYSIS OF THE PREVALENCE RATE OF HYPERTENSION RELATING TO AGES

本文试用指数曲线??=de^(bx)模拟了1987年莱芜市疾病监测点血压年龄患病率趁势,拟合良好,为探讨高血压年龄患病率规律,提供了流行病学定量估计指标.不同性别模型中d、b值的差异表明:高血压患病率随年龄增高的幅度女性大于男性.

Applying the index curve ■yy=de^(bx), the author imitates the trend of the prevalence rate of hypertension relating to ages, which is from the village of disease-surveillance in Laiwu in 1987 the results being very much alike. This affords us the quantitatively estimating index of epidemiology for going into the rule of the prevalence rate of hypertension relating to ages. In the different sex models, the difference between d and b number shows that the prevalence rate of hypertension is higher in females than in males with the increase of ages.
