近年来结直肠癌发病率和死亡率持续攀升,化疗已成为结直肠癌重要的治疗手段之一。 随着《国民营养计划 (2017—2030 年)》的发布,患者营养素养水平逐渐受到医务人员重视,营养素养水平高低已成为影响结直肠癌化疗患者肿瘤 预后的重要因素之一。 营养素养定义是建立在健康素养定义基础之上,两者相互补充又各具特点,目前学者们对于营养素养 的定义虽然存在不同见解,但是都强调个人对营养相关知识的掌握,培养其营养相关问题决策的能力,运用相关信息做出正 确的营养决策。 患者营养素养水平可以提示医务人员其营养知识储备水平,对饮食行为也具有预测价值,同时作为营养干预 的核心内容,不同人群受教育程度、认知水平等存在差异也会导致个体营养素养水平较低,从而影响其健康与发展。 本文通 过对结直肠癌化疗患者营养素养概念框架、研究现状、评估工具、干预模式进行综述,以期优化医务人员对患者营养素养水平 的管理,提高结直肠癌患者的营养素养水平,改善患者的化疗效果和肿瘤预后。
