Abstract: Objective To evaluate the nutritional status of elderly patients with fracture, used by mini nutritional assessment (MNA-SF). Methods Total 1353 cases of hospitalized elderly patients with fracture were included. The MNA-SF investigations were completed within 3 days after admission. The relationships among nutritional status and different ages, with or without exercise, different fracture site, with different diseases were analyzed. Results There were statistical significances about the sum of rates of malnutrition risk and malnutrition among different ages, between with and without exercise, between femoral intertrochanteric fracture and upper limb fracture (P=0.000). There were statistical significances about the sum of rates of malnutrition risk and malnutrition between patients with cardiovascular disease and two kinds of diseases, between patients with cardiovascular disease and three kinds of diseases, between cerebral vascular diseases and two kinds of diseases, between cerebral vascular diseases and three kinds of disease (P=0.001; P=0.001; P=0.001; P=0.004). Conclusion Patients aged 70~90 years old, with no regular exercise, intertrochanteric fracture, diabetes mellitus or a variety of chronic disease a higher incidence of malnutrition risk and malnutrition.
