AbstractObjective: To evaluate changes in nutritional status of hospitalized patients with different diseases by subjective global assessment (SGA) and nutritional risk screening (NRS-2002). Methods: A prospective and parallel research done by multi-center collaboration from 34 hospitals in China from June to September 2014. Hospitalized patients with the following diseases were investigated: malignant tumor (2 487 cases), benign disease of the digestive system (1 358 cases), benign disease of the nervous system (1 043 cases), benign bone disease (451 cases), benign disease of the respiratory system(395 cases), cardiovascular disease (227 cases), benign thyroid and breast disease (179 cases), and endocrine disease (149 cases). Patients above the age of 18 and hospitalization time between 7-30 days were included. Physical indexes were measured, the NRS-2002 and SGA scores were recorded, the nutritional support were recorded during hospitalization and 24 hours after discharge from hospital. Measurement data between groups were analyzed using t test or Wilcoxon rank sum test, enumeration data and ranked data between groups were analyzed using chi-square test or Fisher exact test. Results: There were 6 638 cases of hospitalized patients, 3 861 cases were males and 2 777 were females, the male/female ratio was 1.4∶1.0; the median age was 60 years; the median height was 1.66 m; the median weight was 62 kg; the median body mass index (BMI)was 22.89 kg/m(2). At discharge, compared with that of admission, the body weight, BMI, grip strength, upper arm and calf circumferences of patients with malignant tumor were significantly decreased (t=20.15-259.67, all P<0.01); the body weight and calf circumference were significantly decreased (t=35.27, 60.40, P<0.01)of patients with digestive benign disease; the body weight of patients with benign bone diseases was decreased (t=2.12, P=0.033); the body weight, grip strength and upper arm circumference were decreased in patients with benign thyroid and breast disease (t=2.79-10.18, all P<0.01); nutritional risk incidence rate (from NRS-2002) of patients with malignant tumor was significantly higher(χ(2)=21.275, P=0.000); moderate malnutrition (from SGA) incidence rate was significantly higher(χ(2)=62.318, P=0.000; χ(2)=11.312, P<0.01) in patients with malignant tumor and with orthopedics diseases. Compared with that of admission, records of the patients with other diseases had no statistically difference at discharge, no more than 50% of the patients under risk of nutritional deficiency(except those with digestive benign diseases )received nutritional support, while the proportion of non-parenteral nutrition application was higher. Conclusion: The patients with malignant tumor have higher incidence rate of malnutrition on admission and at discharge. Doctors should pay more attention to the nutritional status(screening and evaluation) of patients before discharge and use appropriate and adequate nutrition support in order to prevent the weight loss and improve the life quality of patients.
