健康老龄化的过程可以通过绘制与健康有关的变量随时间变化的轨迹来最好地描述。不幸的是，只包括幸存者数据的图表可能会产生误导，因为它们可能会混淆死亡率模式和健康变化模式。在这种情况下，有两种方法可以创建说明死亡的图表：1）将死亡的类别或值纳入纵向健康变量; 2）测量死亡或其他事件发生前的时间（以年为单位）。第一种方法已被应用于自评健康（优秀到差）和36项健康调查简表（SF-36）。它允许灵活和可解释的分析，并可能适用于其他变量。第二种方法也完全解释了死亡，但它能解决的问题有限。这两种方法都是有用的，应至少用于支持纵向研究中的分析，其中人员在观察期间死亡。
The process of healthy aging can best be described by plotting the trajectory of health-related variables over time. Unfortunately, graphs including data only from survivors may be misleading because they may confuse patterns of mortality with patterns of change in health. Two approaches for creating graphs that account for death in such situations are 1) to incorporate a category or value for death into the longitudinal health variable and 2) to measure time in years before death or some other event. The first approach has been applied to self-rated health (excellent to poor) and the 36-Item Short-Form Health Survey (SF-36). It allows for flexible and interpretable analyses and may be appropriate for other variables as well. The second approach also accounts fully for death, but the questions it can address are limited. Both approaches are useful and should be used at a minimum for supporting analyses in longitudinal studies in which persons die during observation.
