【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(P0.05),MNA和MNA-SF评价营养状况等级的Spearman相关系数为0.681(P0.05),MNA和MNA-SF评价营养状况的一致性好(κ=0.681,P0.001)。以BMI18.5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。
[Abstract]:Objective to evaluate the nutritional status of the elderly in the community by using the micro nutrition evaluation method (MNA-SFV) and the micro nutrition evaluation method (MNA-SF), and to compare the application value of the two methods in the evaluation of the community elderly's nutritional status. Methods A total of 576 elderly people aged 60 and above in Jinan community were randomly selected. Nutritional status was evaluated by MNA and MNA-SF, and anthropometric and laboratory indexes were detected. Results the average time of MNA was 10 minutes and the average time of MNA-SF was 3 min.MNA. The proportion of normal nutrition was 79.93, the proportion of potential malnutrition was 20.077.The proportion of normal nutrition measured by MNA-SF was 80.48, and the proportion of malnourished was 19.52.The results showed that the average time of MNA-SF was 79.93, the proportion of potential malnutrition was 20.077.The proportion of normal nutrition measured by MNA-SF was 80.48, and the proportion of malnourished was 19.52%. Both of them were positively correlated with the traditional nutritional evaluation indexes, such as BMI-MACMACMACHCTSFSF-ALB and so on. The Pearson correlation coefficients of MNA and MNA-SF scores were 0.823 P0.05MNA and 0.681P0.05MNA and MNA-SF were consistent (魏 0.681P0.001). The sensitivity of BMI18.5 was 76. 2%, the specificity was 93. 4% and the sensitivity of MNA-SF was 100. The specificity was 99. 8%. Conclusion both MNA and MNA-SF can be used to evaluate the nutritional status of the elderly in community. MNA-SF is more simple and effective than MNA.
