Abstract: Objective: To explore the application effect of the nutrition education program based on the transtheoretical model in esophageal cancer patients undergoing radiotherapy. Methods: A total of 110 esophageal cancer patients receiving radiotherapy from June 2024 to December 2024 were selected as the study subjects and divided into the control group (55 cases) and the study group (55 cases) according to the patients suquence of admission. The control group received conventional nutrition education, while the study group received the transtheoretical model based nutrition education program. Both groups were intervened for 6 months. Differences in nutrition knowledge-attitude-practice levels, quality of life, and clinical nutrition indicators were compared before and after the intervention between the two groups. Results: A total of 108 patients completed the study, with 54 in the control group and 54 in the study group. After 6 months of intervention, the study group showed higher scores in nutrition knowledge-attitude-practice levels and quality of life than the control group, with statistically significant differences (P<0.05). The study group also exhibited better improvements in nutritional indicators such as body mass index, triceps skin fold thickness, albumin, and hemoglobin compared to the control group, with statistically significant differences (P<0.05). Conclusion: Implementing a nutrition education program based on transtheoretical models for esophageal cancer radiotherapy patients can improve their nutritional knowledge, attitudes, and behavioral levels, thereby improving their nutritional status and quality of life.

摘要： 目的：探讨基于跨理论模型的营养教育方案在食管癌放疗患者中的应用效果。方法：以 2024 年 6 月至 2024 年 12 月收治的110 例食管癌放疗患者作为研究对象，按照患者入院先后顺序分为对照组（55 例）和研究组（55 例）。对照组实施常规营养教育，研究组实施基于跨理论模型的营养教育方案，两组持续干预 6 个月。比较两组干预前后营养知识-态度-行为水平、生活质量及临床营养指标差异。结果：共 108 例患者完成了研究，对照组 54 例，研究组 54 例。干预 6 个月后，研究组患者营养知识-态度-行为水平、生活质量得分高于对照组，差异均有统计学意义（P<0.05）；研究组患者身体质量指数、肱三头肌皮褶厚度、白蛋白、血红蛋白等营养指标改善状况优于对照组，差异均有统计学意义（P<0.05）。结论：对食管癌放疗患者实施基于跨理论模型的营养教育方案，可提高患者的营养知识、态度、行为水平，从而改善患者的营养状况及生活质量。
