Abstract: ObjectiveNutrition Risk Screening 2002 (NRS2002) and MiniNutritional Assessment (MNA) were applied in nutritional assessment for elderly diabetic nephropathy(DN) of hospitalized patients， and appropriate nutritional assessment methods， as well as the implementation of nutrition interventions for the population were explored. MethodsA total of 210 elderly hospitalized DN patients were evaluated with NRS2002 and MNA for nutritional screening. Simultaneously assessment was made in the prevalence of malnutrition by measuring body mass index(BMI)，arm muscle circumference(AMC)， calf circumference (CC) and total protein (TP)， albumin(ALB)，prealbumin (PA). Kappa value of the two nutritional measurements，i.e. NRS2002 and MNA were compared to analyze the accuracy of the two methods，and correlation analysis was conducted for the two methods and traditional indicators. ResultsFor 210 cases of elderly patients with DN， two evaluation methods gave different nutrient malnutrition incidence results (17.1%40.5%)， NRS2002 was 37.1%， MNA 40.5%， anthropometric indexes evaluation was 17.1%， laboratory parameters evaluated method was 20.5%. MNA and NRS2002 scores were TP， ALB， PA， BMI， AMC and CC relevant. NRS2002 nutrition risk screening and MNA consistency test showed significant difference(Kappa=0.612，P<0.01). ConclusionCompared with the traditional nutritional evaluations， MNA and NRS2002 as comprehensive nutritional assessment methods， are more comprehensive and accurate.
