Abstract: Objective To investigate and evaluate the nutritional status of hospitalized elderly patients, and explore the risk factors of malnutrition in hospitalized elderly patients, so as to provide basis for nutritional support for elderly patients. Methods A random sampling method was adopted to select the elderly patients who participated in nutrition consultation in the nutrition Department of Sanming Hospital of Integrated Chinese and Western Medicine from January 2023 to December 2023. The 262 elderly patients were enrolled by nutritional risk screening (NRS2002) and subjective overall assessment (SGA) for comprehensive nutritional status assessment. 262 questionnaires were distributed and 262 valid questionnaires were recovered, with an effective rate of 100%. The data of laboratory examination indicators and clinical data of patients were analyzed, and the influencing factors of malnutrition were analyzed by logistic regression. Results In this study, the incidence of nutritional risk (NRS≥3 points) and malnutrition was 81.3% and 72.9% in 262 elderly patients consulted by the Department of Nutrition. According to whether they had malnutrition, they were divided into malnutrition group (n=191) and good nutrition group (n=71). logistic multivariate analysis found that, Infection, activity, disease type and sufficient diet were the influencing factors of malnutrition in elderly patients (P <0.05). Conclusion The incidence of nutritional risk and malnutrition in hospitalized patients aged 65 and above is high. The occurrence of malnutrition in hospitalized elderly patients is related to many factors. Clinical attention should be paid to malnutrition identification and nutrition intervention as soon as possible.
