摘　　要：Objective To assess nutritional status and define gender-and age-specific handgrip strength（HGS） cut-point values for malnutrition or nutritional risk in elderly inpatients. Methods A cross-sectional study of 1,343 elderly inpatients was conducted in the Chinese PLA General Hospital. Nutrition Risk Screening（NRS 2002） and Subjective Global Assessment（SGA） were administered. Anthropometric measurements and blood biochemical indicators were obtained using standard techniques. The gender-and age-specific receiver operating characteristic（ROC） curves were constructed to evaluate the HGS for nutritional status by SGA and NRS 2002. Sensitivity, specificity, and areas under the curves（AUCs） were calculated. Results According to NRS 2002 and SGA, 63.81% of elderly inpatients were at nutritional risk and 28.22% were malnourished. Patients with higher HGS had an independently decreased risk of malnutrition and nutritional risk. The AUCs varied between 0.670 and 0.761. According to NRS 2002, the optimal HGS cut-points were 27.5 kg（65-74 years） and 21.0 kg（75-90 years） for men and 17.0 kg（65-74 years） and 14.6 kg（75-90 years） for women. According to SGA, the optimal HGS cut-points were 24.9 kg（65-74 years） and 20.8 kg（75-90 years） for men and 15.2 kg（65-74 years） and 13.5 kg（75-90 years） for women. Conclusion Elderly inpatients had increased incidence of malnutrition or nutritional risk. HGS cut-points can be used for assessing nutritional status in elderly inpatients at hospital admission in China.Objective To assess nutritional status and define gender-and age-specific handgrip strength（HGS） cut-point values for malnutrition or nutritional risk in elderly inpatients.
