Abstract Objective To evaluate the nutritional status of elderly medicine patients with MNA-SF， to analyze the relationship between nutritional status， sarcopenia and other related factors， and to propose better clinical strategies on the evidences of nutrition treatment for elderly patients. Methods A total of 200 cases of patients aged more than 65 older who received treatment in the elderly medicine of the first affiliated hospital of Kangda college of Nanjing medical university from June 2017 to December 2017 were enrolled in this study. According to the scores of MNA-SF， the patients were divided into normal nutritional group， risk of malnutrition group and malnutrition group. The body composition was measured by body composition analyzer and in the meantime， grip strength， stride speed and laboratory index were evaluated. Results Among the 200 elderly medicine patients， the incidence of normal nutritional status， the risk of malnutrition and malnutrition were 50.5%， 26.5% and 23.0%， respectively. The prevalence of sarcopenia was significantly different between three groups， and the prevalence of sarcopenia in malnutrition group was higher than that in the risk of malnutrition group and the normal nutrition group (P<0.05). The levels of albumin， prealbumin， hemoglobin， body mass index， skeletal muscle， appendicular skeletal muscle mass index， grip strength and stride speed were significantly different between three groups (P<0.05). Conclusions There is a high proportion of malnutrition risk and malnutrition in elderly patients. Patients with malnutrition were more likely to suffer from sarcopenia. Timely nutritional treatment is necessary.
