Abstract:

Objective

To investigate the incidence and influencing factors of nutritional risk in hospitalized patients with acute ischemic stroke (AIS).

Methods

Patients with AIS admitted to the Neurology Department of Changying Campus, Beijing Chaoyang Hospital, Capital Medical University from August 1, 2024, to July 31, 2025, were retrospectively included. Nutritional status was assessed using the Controlling Nutritional Status Index (CONUT) score, the Geriatric Nutritional Risk Index (GNRI), and the Prognostic Nutritional Index (PNI). The incidence of nutritional risk in AIS patients was calculated, and multivariate Logistic regression analysis was used to analyze the related influencing factors.

Results

A total of 691 AIS patients were included. The incidence of nutritional risk assessed by CONUT score, GNRI score, and PNI score was 53.26%, 12.45%, and 2.17%, respectively. Multivariate Logistic regression analysis based on CONUT score showed that age (OR=1.031, 95%CI: 1.014 – 1.048), history of coronary heart disease (OR=1.934, 95%CI: 1.243 – 3.007), and renal insufficiency (OR=2.123, 95%CI: 1.038 – 4.342) may increase nutritional risk upon admission in AIS patients. According to the GNRI score, multivariate Logistic regression analysis showed that renal insufficiency (OR=73.631, 95%CI: 21.675 – 250.126) may increase nutritional risk upon admission in AIS patients, while body mass index (BMI; OR=0.491, 95%CI: 0.413 – 0.583) may be a protective factor.

Conclusion

Age, history of coronary heart disease, and renal insufficiency are risk factors for nutritional risk upon admission in AIS patients, while BMI is a protective factor.
