Objective To explore the relationship between the nutritional status of elderly in-patients and the handgrip strength and skeletal muscle mass.

Method  Nutritional risk screening (NRS-2002) was performed on 142 elderly inpatients who were newly admitted to the General Practice Department of Central Hospital of Wuhan from October 2020 to December 2020. The weight, height, BMI, waist circumference, Crus circumference, hip circumference, arm circumference, grip strength, skeletal muscle and body fat were measured. The blood hemoglobin, albumin, total protein and other biochemical indicators reflecting the nutritional status of the body were counted. Pearson correlation and Spearman correlation were used to analyze the correlation of nutritional status with HGS and SMM.

Result  The NRS-2002 score of elderly inpatients showed that the proportion of malnutrition risk (score≥3) was 12.6%(18/142), and the grip strength of malnutrition risk group was significantly lower than that of non-nutrition risk group (score<3) [(18.45±10.330) kg/m² vs. (23.49±8.796) kg/m², P=0.028]. The crus circumference of malnutrition risk group was lower than that of non-nutrition risk group [(32.06±3.809) cm vs (33.91±3.069) cm, P=0.022].

Conclusion  Analysis showed that grip strength was negatively correlated with NRS-2002 score, positively correlated with hip circumference, calf circumference, hemoglobin and SMM, and negatively correlated with age. Skeletal muscle mass was positively correlated with grip strength, but not with NRS-2002 score, and positively correlated with waist circumference, hip circumference, upper arm circumference, calf circumference, hemoglobin and albumin Conclusion handgrip strength and skeletal muscle mass can be used as nutritional screening methods for elderly inpatients.
