RESUMEN
Objective:This study investigated the nutritional risk and malnutrition of patients with digestive system malignant tumors in the day ward and evaluated the risk of comorbidity with nutritional risk and the risk factors of malnutrition in this population.Methods:A cross-sectional study was conducted to collect patients with malignant tumors of the digestive system who were admitted to the day ward of our hospital from November 23,2020,to December 14,2020.The Nutritional Risk Screening Form(NRS 2002)was used for nutritional risk screening,and the Subjective Assessment of Overall Nutritional Status(PG-SGA)was used to assess malnutrition,to investigate nutritional risk and prevalence of malnutrition,and to analyze potential influencing factors.Results:Among the 464 patients with malignant tumors of the digestive system in the day ward,the incidence of nutritional risk was 26.9％,the incidence of malnutrition was 34.7％,and the incidence of severe malnutrition was 14.2％.Multivariate analysis showed that patients with Karnofsky Performance Status(KPS)score＜90 and hypoproteinemia were more likely to have nutritional risk(P＜0.05).Patients with KPS score＜90 and chemotherapy cycles＞6 were more likely to be malnourished(P＜0.05).Conclusions:Digestive system malignant tumor patients in the day ward still have a high proportion of nutritional risks and malnutrition.For patients with KPS score＜90,hypoalbuminemia,and chemotherapy cycles＞6,nutrition issues should be given special attention.
