很难区分衰老引起的健康变化和死亡引起的健康变化，因为这两个过程高度相关。一些潜在的可治疗的疾病可能会被错误地认为是由于年老而被忽视。本文的目的是检查衰老和死亡与10个健康相关变量变化的关系：自评健康、抑郁、ADL、IADL、最低状态检查、体重指数、每周步行街区、住院天数、住院时间和步行速度（所有编码都是为了使值越高越好）。我们使用来自心血管健康研究的纵向数据来估计与5岁老龄化相关的变量的变化，以及死亡前5年的变化，分别控制死亡后的年份和年龄。所有10个健康变量都随着死亡的临近而下降，其中大多数也随着年龄的增长而下降。死亡过程的“影响”通常明显大于衰老的影响。这些健康指标的大幅下降可能不是由于衰老，患者及其提供者应该认真对待。(C)2002年爱思唯尔科技有限公司All rights reserved.
It is difficult to distinguish changes in health due to aging from those related to dying, because the two processes are highly related. Some potentially treatable conditions may mistakenly be dismissed as due to old age. The goal of this article was to examine the relationships of aging and of dying to changes in 10 health-related variables: self-rated health, depression, ADLs, IADLs, minimental state examination, body mass index, blocks walked per week, bed days, hospitalization, and walking speed (all coded so that higher values were better). We used longitudinal data from the Cardiovascular Health Study to estimate the changes in the variables associated with 5 years of aging and also in the 5 years before death, controlling for years from death and for age, respectively. All 10 health variables declined as death approached, and most of them also declined with age. The "effect" of the dying process was usually significantly larger than the effect of aging. Large declines in these health measures are probably not due to aging, and should be taken seriously by patients and their providers. (C) 2002 Elsevier Science Inc. All rights reserved.
