摘　　要：目的利用微型营养评价法(MNA)和微型营养评价精法(MNA-SF)评价社区老年人的营养状况,比较二者在社区老年人营养状况评价中的应用价值。方法随机抽取济南市社区60岁及以上老年人576例,应用MNA和MNA-SF评价营养状况,并检测人体测量指标和实验室指标。结果 MNA平均用时10 min,MNA-SF平均用时3 min。MNA测得的营养正常者所占比例为79.93%,潜在营养不良者占20.07%,未发现营养不良者。MNA-SF测得的营养正常者所占比例为80.48%,营养不良者占19.52%。二者均与BMI、MAC、CC、WC、HC、TSF、SSF、ALB等传统营养评价指标呈正相关(r=0.001~0.530,P均<0.05),MNA和MNA-SF得分的Pearson相关系数为0.823(P<0.05),MNA和MNA-SF评价营养状况等级的Spearman相关系数为0.681(P<0.05),MNA和MNA-SF评价营养状况的一致性好(κ=0.681,P<0.001)。以BMI<18.5为评价营养不良的标准,MNA的灵敏度76.2%、特异度93.4%,MNA-SF的灵敏度100%、特异度99.8%。结论 MNA和MNA-SF均可以用于评价社区老年人的营养状况,MNA-SF比MNA更为简便、有效。Objective To compare the value of Mini-Nutritional Assessment（ MNA） and the Short-Form Mini-Nutritional Assessment（ MNA-SF） in evaluating the nutritional status of the elderly in community. Methods A total of 576 elderly ≥60 years in Jinan City were randomly selected. MNA and MNA-SF were used to evaluate the nutritional status of the population. The anthropometric parameters and laboratory indexes were also measured. Results MNA took 10 min to complete while MNA-SF only needed 3 min. MNA showed that the proportion of adequate nutritional status was 79.93%,and that of potential malnutrition was 20. 07%,and no malnutrition was found. MNA-SF showed that the proportion of adequate nutritional status was 80. 48% and that of malnutrition was 19. 52%. Both of them were positively correlated with BMI,MAC,CC,WC,HC,TSF,SSF,ALB and other traditional nutritional evaluation indicators（ r = 0.001-0. 530,P〈0. 05）. The Pearson correlation coefficient between MNA and MNA-SF scores was 0. 823（ P〈0. 05）. The Spearman correlation coefficient between MNA and MNA-SF was 0. 681（ P〈0. 05）. MNA and MNA-SF had good consistency in evaluating nutritional status（ κ = 0. 681,P〈0. 001）. With BMI 18. 5 as the evaluation criteria of malnutrition,the sensitivity and specificity of MNA were 76. 2% and 93. 4% respectively,and the sensitivity and specificity of MNA-SF were 93. 4% and 100% respectively. Conclusion Both MNA and MNA-SF can be used to evaluate the nutritional status of elderly from community,and MNA-SF is more simple,rapid and effective.
