| Summary: | Objective To explore the risk factors for malnutrition (MN) in elderly patients with long-term bed and to construct a risk prediction model for MN.Methods Elderly patients with long-term bed admitted to the Department of Geriatrics of the Fourth People's Hospital of Yaan from January 2016 to January 2024 were retrospectively selected, and their clinical data were collected. The elderly patients with long-term bed were randomly divided into training set and validation set, according to the ratio of 7∶3. The patients were divided into MN group and non-MN group according to whether MN occurred. In the training set, the differences in clinical data between the groups were compared by univariate analysis (t-test, chi-square test or Fisher's exact test), and the risk factors for MN in patients were analyzed by stepwise multivariate Logistic regression, and a risk prediction model was constructed. The predictive efficiency of the risk prediction model was evaluated and verified by the receiver operating characteristic curve (ROC) and ROC area under curve (AUC), calibration curve and decision curve.Results A total of 896 elderly patients with long-term bed were included, and the incidence of MN was 46.43%. There were 627 cases in the training set and 269 cases in the validation set. Multivariate Logistic regression analysis showed that long bed rest time [OR=1.259, 95%CI (1.197, 1.324)], stroke [OR=2.866, 95%CI (1.621, 5.067)], and anemia [OR=2.479, 95%CI (1.162, 5.288)] were risk factors for MN in elderly patients with long-term bed, and high Barthel index score [OR=0.921, 95%CI (0.905, 0.938)] was a protective factor (P |
