Neurology disorders are one of the major public health problems that seriously threaten human health. It often accompanied by various nutritional problems, which can aggravate the primary disease, lead to serious complications, prolong the hospitalization, lead to poor prognosis, and increase family and social economic burdens. According to the previous studies, the risk of malnutrition was approximately 58.5% of stroke patients, and 6% had moderate to severe malnutrition in China. Another study conducted in Beijing showed that the risk of malnutrition of elderly patients in the department of neurology was significantly higher than in other departments (28.5% vs. 26.4%). Strengthening nutritional supervision of patients with neurology disorders will benefit to improve patients' prognosis. Therefore, the aim of this study is to investigate the nutritional status of inpatients with neurology disorders in China, evaluate the impact of different nutritional status on patients' health outcomes, and establish a high-quality, standardized nutrition and health cohort database for neurology disorders.
