应用MNA-SF和NRS2002评价老年结直肠癌患者营养状况

目的旨在通过运用营养风险筛查2002(NRS-2002)及微型营养评估精法(short-form mini-nutritional assessment，MNA-SF)工具对125例老年结直肠癌患者进行营养评估，并探讨NRS2002和MNA-SF与传统营养评价方法的相关性。 方法选定2012年3月至2013年9月哈尔滨医科大学附属第二医院普外科新入院结直肠癌患者125例作为研究对象。患者入院后48小时内采集营养相关指标，并应用NRS-2002和MNA-SF对患者进行营养评估，分析研究对象营养风险的总体情况，计算两种方法与传统指标的相关性。 结果125例结直肠癌患者应答率100%，无额外费用。用BMI中国标准判定营养不足发生率为30.0%，NRS2002营养风险率为32.8%，MNA-SF营养风险率为59.2%，NRS2002与BMI、Alb、Hb呈显著负相关系(P<0.05)，MNA-SF与BMI、Alb、Hb呈显著正相关系(P<0.05)。 结论本组老年结直肠癌患者营养不良发生率较高，NRS2002和MNA-SF均适用于老年结直肠癌患者的营养评估，但尚未发现联合应用的额外获益。

Assessment of the nutritional status of elderly patients with colorectal cancer by MNA-SF and NRS2002

ObjectiveTo assess the nutritional status in elderly patients with colorectal cancer and to analyze the correlation between different tools, and to confirm the correlation of short-form mini nutritional assessment(MNA-SF)along with NRS-2002 with classical nutritional markers. MethodsNutritional status of 125 hospitalized aged patients with colorectal cancer were evaluated by MNA-SF and NRS2002, and at the same time measured their classical nutritional markers.Then the relevance between them was analyzed. ResultsThe prevalence of malnutrition in 125 patients by BMI, MNA-SF and NRS2002 was 30.0%, 59.2% and 59.2% respectively.MNA-SF and NRS2002 had the unanimous correlation with classical nutritional markers. ConclusionThere is a high prevalence of malnutrition in elderly patients with colorectal cancer.MNA-SF and NRS2002 are suitable tools to evaluate the nutritional status of the hospitalized aged patients with colorectal cancer, though the reliability is to be further confirmed in our country.
