Abstract: Objective To assess the reliability and validity of mini nutritional assessment(MNA)scale in community elderly, and to lay the foundation for the development of the new nutrition screening tool suitable for Chinese community elderly. Methods A total of 550 elderly in communities of Jinan were randomly selected and 544 were finally analyzed in our study. MNA scale was used to assess the nutrition status. Anthropometric parameters and laboratory indexes were also measured. The reliability, construct validity and criterion-related validity were calculated and assessed. Results Cronbachs α coefficient of MNA scale was 0.287. Factor analysis yields 9 common factors. Cumulative factor contribution rate was 60.94%. Factor analysis indicated that the factor loads of some items(MNA14 and MNA17)were less than 0.4. There were significant correlations between total MNA score and BMI, MAC and CC. Using BMI and serum 山 东 大 学 学 报 (医 学 版)56卷9期 -袁华财,等.微型营养评价量表在社区老年人群中的信效度评价 \=-albumin as objective criteria for assessing nutritional status, the sensitivity of malnutrition by MNA in older adults was 0.884 with a specificity of 0.683. Kappa value of two methods above for evaluating nutritional status was 0.215. Item analysis suggested that the scores of MNA6, MNA9, MNA10 and MNA12 were not related to total score. Conclusion Although the reliability and validity of MNA indicate this scale is not a reliable assessment tool for nutrition assessment of Chinese community elderly, it is still the cornerstone of the following revise process.

Key words: Mini-nutritional assessment, Community elderly, Reliability, Validity, Nutrition status
