摘要
目的探讨微型营养评价量表(MNA)在老年脑卒中恢复期患者中的适用性及其与生命质量的相关性。方法选取2021年9月至2022年1月在该院就诊的236例老年脑卒中恢复期患者为研究对象。采用自行设计的一般资料调查表和MNA,以面对面逐一询问并填写的方式进行问卷调查,评价MNA的信度及效度。Pearson相关分析和多元逐步线性回归分析老年脑卒中恢复期患者MNA评分与生命质量的关系。结果MNA在老年脑卒中恢复期患者中的Cronbach’sα系数为0.779,重测信度组内相关系数(ICC)为0.939;Bland-Altman分析显示,仅1.27%(3/236)的数据位于一致性界限外。探索性因子分析结果显示,KMO值为0.772,累计方差解释率为65.26%。Pearson相关分析显示,老年脑卒中恢复期患者MNA评分与世界卫生组织生命质量简表(WHOQOL-BREF)评分呈正相关(r=0.623,P<0.001)。多元逐步线性回归分析显示,经校正其他因素后,MNA评分为老年脑卒中恢复期患者生命质量的独立影响因素(β=0.433,95%CI:1.121~2.444,P<0.001)。结论MNA在老年脑卒中恢复期患者中具有较好的信度和效度,MNA评分所反映的营养状况与生命质量密切相关。
Objective To investigate the applicability of the mini nutritional assessment(MNA)scale in elderly patients with stroke convalescent stage and its correlation with the quality of life.Methods Totally 236 elderly patients with stroke convalescent stage visited in the outpatients department of this hospital from September 2021 to January 2022 were selected as the study subjects.The self-designed General Data Questionnaire and MNA Scale were adopted to conduct the questionnaire survey by the ways of face to face one by one inquiry and filling in.The reliability and validity of MNA scale were evaluated.The Pearson correlation analysis and multiple stepwise linear regression were used to analyze the relationship between the MNA score and the quality of life in elderly patients with stroke convalescent stage.Results The Cronbach’sαcoefficient of MNA scale in elderly patients with stroke convalescent stage was 0.779 and the inter-group correlation coefficient of test-retest reliability was 0.939,and the Bland-Altman analysis showed that only 1.27%(3/236)of the data were beyond the consistency limits.The exploratory factor analysis results revealed that the KMO value was 0.772 and the cumulative variance explanation rate was 65.26%.The Pearson correlation analysis showed that the MNA scale score in elderly patients with stroke convalescent stage was positively correlated with the WHOQOL-BREF score(r=0.623,P<0.001).The multiple stepwise linear regression analysis showed that after adjusting other factors,the MNA score was an independent influential factor for the quality of life in elderly patients with stroke convalescent stage(β=0.433,95%CI:1.121-2.444,P<0.001).Conclusion The MNA scale has good reliability and validity in elderly patients with stroke convalescent stage.The nutritional status reflecting by MNA scores is closely related to the quality of life.
