对于认知能力薄弱或痴呆导致死亡的老年人来说，生存预测被认为是困难的。本研究的目的是验证体弱老年人身体质量指数（BMI）、能量摄入和液体摄入量的时间变化作为死亡的预后因素。我们评估了106名体弱多病的老年人，他们在一家老年护理机构接受了2年的护理，并在该机构死亡。我们分析了从死前最多60个月的BMI、能量摄入和液体摄入量的时间变化，并确定了这些参数之间的关系。从死亡前9个月开始，BMI显著低于参考值，但从死亡前2个月到死亡，能量摄入保持不变（p < 0.001）。然而，在死亡之前，平均液体摄入量突然下降。我们比较了死亡前一年和死亡前一年各参数的变化，发现所有参数均有显著差异（p < 0.001）。从死亡前60个月到死亡，BMI、能量摄入和液体摄入按相同的顺序随时间下降。因此，这些参数可作为体弱老年人死亡的预后因素。
Survival prediction is considered difficult in elderly individuals with cognitive frailty or dementia that leads to death. The aim of this study was to verify temporal changes in body mass index (BMI), energy intake, and fluid intake measured continuously in frail elderly people as prognostic factors for death. We assessed 106 frail elderly individuals who received >2-year care at an elderly care facility and died at the facility. We analyzed temporal changes in BMI, energy intake, and fluid intake from a maximum of 60 months premortem to death and determined the relationship between these parameters. BMI was significantly below the reference values from 9 months prior to death, but energy intake remained constant from 2 months prior to death to death (p < 0.001). However, the mean fluid intake decreased suddenly immediately prior to death. We compared the changes in each parameter during the year prior to death and during the preceding year and found significant differences in all parameters (p < 0.001). From 60 months prior to death to death, BMI, energy intake, and fluid intake decreased in the same order over time. Therefore, these parameters can be used as prognostic factors for death in frail elderly people.
