Objective To evaluate the nutritional status of elderly inpatients by using the nutritional risk screening table 2002(NRS2002)and the short-form mini-nutritional assessment(MNA-SF),and to eval-uate the applicability of the two tools.Methods The general data were collected from the inpatients aged ≥80 years old by the random sampling method.They were divided into the two age groups:≥90 years old and＜90 years old,and their nutritional status was assessed by using the two nutritional screening tools.Meanwhile,the fasting venous blood nutritional related indicators including albumin(Alb),hemoglobin(Hb),C-reactive protein(CRP),transferrin(TRF),prealbumin(PA)and retinol-binding protein(RBP)levels were detected.Furthermore the results conducted the correlation analysis.Results There were 404 cases(48.56％)of nutri-tional risk in the NRS2002 evaluation.The occurrence rate of nutritional risk in the ≥90 years old group was higher than that in the＜90 years old group(P＜0.01).There were 616 cases(74.04％)of malnutrition/risk of malnutrition in the MNA-SF evaluation.The incidence rate of malnutrition risk in the≥90 years old group was higher than that in the＜90 years old group(P＜0.01).With the serum ALB＜30 g/L as the ref-erence standard,the applicabilities were compared between the two kinds of nutritional screening tools,the re-sults found that the two kinds of nutritional screening tools all were suitable for the nutritional status screen-ing of elderly inpatients.The area under the receiver operating characteristic(ROC)curve(AUC)of the MNA-SF for evaluating the nutritional status in the elderly inpatients was 0.814,the sensitivity and specificity were 75.7％and 87.7％respectively.AUC of ROC in NRS2002 for evaluating the nutritional status in the elderly inpatients was 0.805,the sensitivity and specificity were 88.6％and 62.2％respectively.The correla-tion analysis results of Hb,CRP,PA,RBP and TRF biochemical indexes with MNA-SF score and NRS2002 score showed that NRS2002 score and MNA-SF score were correlated with PA,RBP and TRF.Conclusion The incidence rate of nutritional risk in elderly inpatients is high.Both NRS2002 and MNF-SF nutritional screening tools are suitable for elderly inpatients and have high accuracy.Meanwhile,combining nutrition-related indicators to evaluate the nutritional status of elderly patients can improve the accuracy of nutritional assessment.
