Abstract: Objective To find out the malnutrition incidence rate and distribution of hospitalized patientswith acute stroke. To investigate the important factors which were related to malnutrition inpatients with acute stroke.Methods Two hundreds and three consecutive patients admitted to hospital with a recent strokewere enrolled. The method of cross-sectional study was used. The main nutrition index was thelevel of serum prealbumin. The diagnosis standard of malnutrition was that the level of serumprealbumin is lower than 200 mg/L. Data on nutritional status, clinical complications and theseverity of nerve functions losses were collected in after hospitalization. The changes of thelevel of serum prealbumin were observed. The correlations between the baseline data, clinicalcomplications and malnutrition were studied. The SPSS 11.5 software was used for statisticalanalysis.Results With the extension of hospital stay, the serum prealbumin levels decreased at differenttime points (P <0.05). There were 110 patients complicated with malnutrition. The incidencerate of malnutrition in hospitalized patients with acute stroke was 54.2% in our research and itincreased with the lasting of the length of stay. Sex, age, infection, alimentary tract hemorrhage,fever, abrosia or gastrointestinal decompression, enteral nutrition, the National Institutesof Health Stroke Scale(NIHSS) scales, cognition disorder, depression after stroke onset andswallowing difficulties were related to malnutrition (P <0.05). After adjustmnet for the otherfactors, age(OR=1.723,95%CI :2.204-15.498), the NIHSS(OR=1.159,95%CI :1.020-1.316) scales and depression (OR=4.604, 95%CI 1.952-10.860) were independent risk factors of malnutrition inpatients with acute stroke.Conclusion There was high incidence rate of malnutrition in hospitalized patients with acutestroke in our research and it increased with the lasting of the length of stay. Age, the NIHSSscales and depression were independent risk factors of malnutrition in patients with acute stroke.
