Objective:To evaluate the nutritional status quo of inpatients with type 2 diabetes by using NRS2002,SGA and MNA-SF,and to analyze the results.Methods:The general information of patients was collected by continuous fixed-point sampling,and 537 inpatients with type 2 diabetes were evaluated by NRS2002 and SGA.Among them,188 elderly inpatients were assessed by MNA-SF.Human body measurements and blood biochemical indexes were performed to analyze the relevant influencing factors of the three nutrition assessment methods.Results:Compared with middle-aged type 2 diabetes inpatients,the height,TC and HB of elderly type 2 diabetes patients were all decreased(P<0.05), while BUN and Cr were significantly increased(P<0.05).Body weight,ALB,TP and TG decreased significantly in elderly male patients (P<0.05),while LC decreased significantly in elderly female patients(P<0.05).According to BMI criteria,the proportions of malnutrition,overweight and obesity was 3.0%,42.7% and 21.4% respectively.According to the SGA assessment,the proportion of malnutrition was 9.9%.According to NRS2002,the composition ratio of nutritional risk was 16.8%.According to the MNA-SF assessment,the constituent ratio of malnutrition was 19.7%.Spearman correlation analysis showed that there was a positive correlation between NRS2002,SGA and MNA-SF(P<0.05).NRS2002,SGA and MNA-SF were positively correlated with body weight,BMI,WC and LC in both male and female inpatients with type 2 diabetes(P<0.05).Conclusion:Type 2 diabetes patients had a higher proportion of overweight and obesity,and NRS2002,SGA and MNA-SF should be combined with gender,age,anthropometric measurement and blood biochemical indexes for comprehensive evaluation.
