Abstract：Objective: To evaluate the value of handgrip strength(HS) index in malnutrition screening for the elderly in a community. Methods: From June to August 2017, at the Huayang Community Health Service Center in Shanghai,we conducted a mini nutrition assessment-short form (MNS-SF) questionnaire based survey in elderly outpatients by fixed point continuous sampling method. Meanwhile, height, weight, calf circumference, handgrip strength were measured. HS index=Handgrip Strength(kg)/height 2(m 2). Results: ① A total of 1 276 elderly people completed questionnaires and 104 people had an MNA-SF score of less than 12 points. Malnutrition risk rate was 8.15%.The difference in HS index between the malnutrition risk group and the normal nutrition group was statistically significant［(8.31±2.45)kg/m2 vs (9.57±2.43)kg/m 2, P=0.000］.There was significant correlation between HS index and age, BMI,calf circumference and MNA-SF score(R＝-0.337，0.160，0.298，0.194, P=0.000）.Multivariate linear regression was performed with leg calf circumference,BMI and HS index as the independent variable and MNA-SF as the dependent variable, it was found that MNA-SF Score=6.895+0.042×HS index+0.229×BMI.② One hundred and four elderly people with MNA-SF greater than 11 points were selected and the parameters were analysed by paired ttest by gender and age, the results showed that there were still statistical differences between the two groups in the grip strength index ［the malnutrition risk group vs the normal nutrition group:(8.31±2.50)kg/m 2 vs (9.78±1.89)kg/m 2, P=0.000］. Conclusion: The grip strength index of the elderly with malnutrition risk were lower, grip strength index could be used as a reference indicator for nutrition screening for the elderly in the community.
