Malnutrition is a common and critical problem that greatly influences the clinical outcomes of hospitalized patients. Nutrition support therapy and food intake, in addition to disease-related factors, are also important to maintain the nutrition status of patients. In light of this, we aimed to examine the risk factors associated with malnutrition in 3 hospitals in China. This project was part of the NutritionDay audit, an international daylong cross-sectional audit investigating the nutritional intervention profiles of hospitalized patients. Seven standardized questionnaires were used, and malnutrition was defined as a body mass index <18.5 kg/m2 or unintentional weight loss >5% in last 3 months. A total of 842 hospitalized patients from 9 units in 3 Chinese hospitals participated in the project on November 19, 2015. Among them, 825 were included in the analyses. Malnutrition was identified in 29.3% of the patients and oral nutrition was the primary nutrition support therapy administered (n = 623, 75.6%). Age, nutrition support, and food intake during the past week were independent risk factors for malnutrition. Furthermore, nutrition status, nutrition support therapy, and food intake during the past week were associated with prolonged length of stay. The prevalence of malnutrition in Chinese hospitals was similar to that in European hospitals. Nutrition status was associated with age, nutrition support, and food intake, which was closely related to patients' clinical outcome, such as prolonged hospital stays as confirmed in this study. More studies are needed to determine why nutrition intake is often inadequate and to determine efficient methods for correcting the nutrition status of patients.
