目的 探讨营养风险管理结合分期饮食指导对溃疡性结肠炎（UC）患者营养状况的影响。方法 选择郑州市大肠肛门病医院收治的90例UC患者，纳入时间为2024年1月—2025年1月，按照计算机分组法分为对照组（45例），给予分期饮食指导，观察组（45例），在对照组的基础上增加营养风险管理，观察两组患者症状改善情况、营养状况、生活质量。结果 干预后，观察组Mayo评分（4.30±1.14）分、主观整体营养状况评价表（PG-SGA）评分（1.74±0.38）分低于对照组（5.48±1.33、2.28±0.43）分（P＜0.05）；观察组血红蛋白（HB）、前白蛋白（PA）、白蛋白（ALB）水平高于对照组（P＜0.05），IBDQ各维度评分及总分更高（P＜0.05）。结论 对UC患者应用营养风险管理结合分期饮食指导，能够减轻临床症状，改善营养状况，促进生活质量的提升。

       Objective To explore the influence of nutritional risk management combined with staged dietary guidance on the nutritional status of ulcerative colitis（UC）patients．Methods A total of 90 UC patients admitted to our hospital were selected and included from January 2024 to January 2025．According to the computer grouping method，45 cases were divided into control group with staged dietary guidance，and 45 cases were divided into observation group with nutritional risk management．The symptoms improvement，nutritional status，and quality of life of the two groups were observed．Results After intervention，the observation group had lower Mayo score（4.30±1.14）and Patient?Generated Subjective Global Assessment（PG-SGA）score（1.74±0.38）than the control group（5.48±1.33 and 2.28±0.43，respectively）（P＜0.05）；the observation group had higher levels of hemoglobin（HB），prealbumin（PA），and albumin（ALB）than the control group（P＜0.05），and also had higher scores in all dimensions and total score of the Inflammatory Bowel Disease Questionnaire（IBDQ）（P＜0.05）．Conclusions The application of nutrition risk management combined with staged dietary guidance in UC patients can reduce clinical symptoms，improve nutritional status，promote the improvement of life quality．
