基于多目标规划的成年炎症性肠病患者健康膳食推荐模型研究 后印本

Краткое изложение: Background  Diet is a critical component of health management for patients with inflammatory bowel disease（IBD），and modeling healthy dietary recommendations can help provide patients with tools to aid in dietary management and disease recovery. Objective  To construct and validate a healthy dietary recommendation model for adult patients with IBD. Methods  A research group was set up to clarify the recommended nutrient groups and intakes for IBD patients using literature research and Delphi expert consultation method，to screen nutrients with anti-inflammatory or pro-inflammatory properties，to identify patients' dietary preferences using food-frequency matrix method，and to establish a model for recommending healthy diets to patients with IBD using multi-objective optimization algorithms and collaborative filtering algorithm. Using purposive sampling and maximum variation sampling，20 IBD adult patients were selected from a tertiary hospital in Nanjing in December 2023，and the model was applied to recommend personalized dietary types and intake for IBD patients using a multi-objective particle swarm algorithm and collaborative filtering algorithm to validate the model's feasibility and scientificity. Results  The model of healthy dietary recommendations for IBD adult patients needs to meet the three main goals of nutritional needs，complementary therapies and dietary preferences at the same time. Nutritional requirements are mainly considered in six indicators：energy，protein，dietary fiber，vitamin D，calcium and iron；adjuvant therapy is based on the comprehensive consideration of seven anti-inflammatory nutrients such as dietary fiber，vitamin A，vitamin C，vitamin E，selenium，magnesium and zinc，as well as the four major pro-inflammatory nutrients such as energy，fat，protein and iron；and algorithmic solving results in a personalized dietary recommendation plan in line with the dietary preferences of the 20 patients with IBD. The validation results showed that the average accuracy of the model's food group recommendations was 95.5%，and the average nutrient error was 12.60%. Conclusion  The model of healthy dietary recommendations for IBD adult patients constructed in this study is accurate and effective and helps to improve the refinement of IBD dietary management.
