Nutritional status was assessed according to the Global Leadership Initiative on Malnutrition diagnostic criteria, and risk factors associated with malnutrition were identified through univariate and logistic regression analyses. Based on the findings, a nomogram was developed, and a calibration curve model was constructed. The predictive performance of the model was evaluated using the receiver operating characteristic (ROC) curve. Finally, the model was validated using an independent cohort of 78 patients.Results: Data analysis revealed that among the 182 elderly patients with hip fractures, 76 were men and 106 were women, with a mean age of 75.77 ± 8.66 years. The fractures included 135 femoral neck fractures and 47 intertrochanteric fractures. Malnutrition was identified in 39.01% (71/182) of the patients. Independent risk factors for malnutrition included age, body mass index, the number of comorbidities, haemoglobin level and serum albumin level. A nomogram model incorporating these indicators was developed, demonstrating robust predictive performance, with an area under the ROC curve of 0.886 (95% confidence interval: 0.809– 0.962).Conclusion: It is anticipated that the proposed model will serve as a valuable tool for the timely and accurate clinical identification of malnutrition risk in elderly patients with hip fractures.Keywords: malnutrition, older adults, hip fracture, prediction model |
