Abstract: Objective To analyze the influencing factors of the nutritional status in the elderly patients with stroke during convalescence by comprehensive geriatric assessment (CGA). Methods A total of 114 patients with stroke ( age≥60 years old, the length of stay>24 h) in our hospital from August 2019 to April 2021 were selected, and were divided into 3 groups: the old aged group (aged ≥80 years old, n=38), the middle aged group ( aged 70-79 years old, n=40) and the young aged group ( aged 60-69 years old, n=36). The nutritional status of the patients were assessed by mini-nutritional assessment (MNA). All the patients received CGA. The influencing factors of malnutrition in the elderly patients with stroke during convalescent were analyzed by multivariate Logistic regression. Results Among the 114 patients, 34 patients presented with malnutrition risk (29.82%) and 32 patients with malnutrition (28.07%). There was significant difference in the incidence of malnutrition between the old aged group and the young aged group (P< 0.05). Multivariate Logistic regression analysis showed that age, the course of stroke, activities of daily living, dysphagia, tooth loss or aging affecting eating, psychological disorders, cognitive impairment and offspring looking after their parents were the independent influencing factors of malnutrition in the elderly patients with stroke during convalescence. Conclusions CGA can more comprehensively evaluate the influencing factors of nutritional status in the elderly patients with stroke during convalescence, which is helpful for the development of individualized management measures.
