Abstract
AbstractBackgroundThe objective of this study is to examine the association between the Geriatric Nutritional Risk Index (GNRI) and overall mortality in this population.MethodsGNRI 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.ResultsGNRI 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.ConclusionThe 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.
