Abstract

Background: The objective of this study is to examine the association between the Geriatric Nutritional Risk Index (GNRI) and overall mortality in this population.

Methods: GNRI values were calculated by using the serum albumin levels and body weight and the GNRI variability reflects the changes in GNRI change slopes in the follow-up.

Results: GNRI values showed a decrease from the median baseline GNRI of 106.3 (IQR, 95.0,113.4) to 98.4 (interquartile range [IQR], 91.9108.9) (p < 0.001). The median GNRI variability was 4.7 (IQR, 2.5, 10.3). Both baseline GNRI levels (adjusted odds ratio [OR]: 0.96, 95% confidence interval [CI]: 0.93, 0.99, p = 0.04) and more profoundly GNRI variability (adjusted OR: 1.23, 95% CI: 1.01, 1.44, p = 0.03) were independently associated with mortality.

Conclusion: The monitorization of the changes in GNRI values as a variability index is an easy tool that might improve the predictive accuracy of mortality in peritoneal dialysis patients.

老年营养风险指数变异性与腹膜透析患者死亡率之间的关系。

背景:本研究的目的是研究老年营养风险指数(GNRI)与该人群总死亡率之间的关系。方法:采用血清白蛋白水平和体重计算GNRI值，GNRI变异性反映随访期间GNRI变化斜率的变化。结果:GNRI值从基线GNRI的中位数106.3 (IQR, 95.0113.4)下降到98.4(四分位间距[IQR]， 91.9108.9) (p)。结论:监测GNRI值的变化作为变变性指标是一种简便的工具，可以提高腹膜透析患者死亡率的预测准确性。
