Background The nutrition status of coronavirus disease 2019 patients is unknown. This study evaluates clinical and nutrition characteristics of severely and critically ill patients infected with severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) and investigates the relationship between nutrition risk and clinical outcomes. Methods A retrospective, observational study was conducted at West Campus of Union Hospital in Wuhan. Patients confirmed with SARS‐CoV‐2 infection by a nucleic acid–positive test and identified as severely or critically ill were enrolled in this study. Clinical data and outcomes information were collected and nutrition risk was assessed using Nutritional Risk Screening 2002 (NRS). Results In total, 413 patients were enrolled in this study, including 346 severely and 67 critically ill patients. Most patients, especially critically ill patients, had significant changes in nutrition‐related parameters and inflammatory markers. As for nutrition risk, the critically ill patients had significantly higher proportion of high NRS scores ( P < .001), which were correlated with inflammatory and nutrition‐related markers. Among 342 patients with NRS score ≥3, only 84 (of 342, 25%) received nutrition support. Critically ill patients and those with higher NRS score had a higher risk of mortality and longer stay in hospital. In logistic regression models, 1‐unit increase in NRS score was associated with the risk of mortality increasing by 1.23 times (adjusted odds ratio, 2.23; 95% CI, 1.10–4.51; P = .026). Conclusions Most severely and critically ill patients infected with SARS‐CoV‐2 are at nutrition risk. The patients with higher nutrition risk have worse outcome and require nutrition therapy.
