摘要：

目的 研究主观综合性营养评估(subjective global assessment,SGA)、营养不良-炎症评分(malnutrition inflammation score,MIS)和微型营养评定简表(mini nutrition assessment short form,MNA-SF)3种方法用于维持性血液透析(maintenance hemodialysis,MHD)患者营养评估的差异。 方法 MHD患者120例，对其进行问卷调查、体格检查，分别计算SGA、MIS和MNA-SF营养评分，进行营养评分的两两相关性分析，并根据SGA＜25分为营养不良标准，对MIS、MNA-SF行受试者工作特征(ROC)曲线分析。 结果 相关性分析发现SGA、MIS和MNSA-SF之间有显著相关性(P＜0.01)。MNA-SF的ROC曲线下面积为0.342，MIS的ROC曲线下面积0.689,当MIS为6.5分时，敏感性(70.00%)、特异性(61.70%)最高。 结论 MIS用于MHD患者的营养评估效果与SGA相似，MNA-SF不适用于MHD患者，同样不适用于老年(年龄≥60岁)MHD患者。

Abstract:

Objective To study the differences of nutritional status in maintenance hemodialysis (MHD) patients assessed by Subjective Global Assessment (SGA), Malnutrition Inflammation Score (MIS) and Mini Nutritional Assessment-Simple Form (MNA-SF). Methods SGA, MIS and MNA-SF were used to assess the nutritional status in 120 MHD patients, and correlations were analyzed among the results from the 3 methods. Receiver operating characteristic (ROC) curve was applied to study the sensitivity and specificity of the 3 methods for the evaluation of malnutrition status. Results A strong correlation existed among SGA, MIS and MNA-SF (P＜0.01). Area under the ROC curve of MNA-SF and MIS was 0.342 and 0.689, respectively, for malnutrition diagnosed by SGA score of ＜25. When the MIS score was >6.5, the sensitivity (70.00%) and specificity (61.70%) was highest. Conclusion MIS is similar to SGA for malnutritional assessment in MHD patients. MNA-SF is unsuitable for this purpose, neither for the assessment in elderly (age ≥60 years) MHD patients.
