目的：使用人体测量和血清蛋白测量相结合作为评估蛋白质-能量营养不良 (PEM) 的标准，评估主观整体评估 (SGA) 和迷你营养评估 (MNA) 的有效性。设计：连续选择 65 岁以上居民的横断面研究。地点：瑞典南部的一个市。对象：从 1996 年 10 月开始的一年内，148 名女性和研究纳入了113名年龄大于或等于65-104岁、新入住特殊类型老年人住房的男性。结果：根据SGA，53%的人在入院时被评估为营养不良或中度营养不良。 MNA 的相应数字是 79% 的人营养不良或面临营养不良的风险。两种工具均表明，被分类为营养不良的居民的人体测量值和血清蛋白显着较低（P < 0.05）。检测 PEM 的灵敏度在 SGA 中为 0.93，在 MNA 中为 0.96，特异性为 0.61 和 0.26。通过回归分析，体重指数和血清白蛋白是预测 SGA 和 MNA 分类的最佳客观营养参数。 SGA 中的“肌肉萎缩”项目和 MNA 中的“自我经历的健康状况”对于被评估为营养不良的几率显示出最强的预测能力。结论：SGA 被证明是检测已确定营养不良的居民的更有用的工具，而 MNA 是检测需要预防性营养措施的居民的更有用的工具。
Objectives: To evaluate the Subjective Global Assessment (SGA) and the Mini Nutritional Assessment (MNA) with regard to validity using a combination of anthropometric and serum-protein measurements as standard criteria to assess protein-energy malnutrition (PEM).Design: Cross-sectional study with consecutive selection of residents aged greater than or equal to 65 y.Setting: A municipality in the south of Sweden.Subjects: During a year, starting in October 1996, 148 females and 113 males, aged greater than or equal to 65-104 y of age, newly admitted to special types of housing for the elderly, were included in the study.Results: According to SGA, 53% were assessed as malnourished or moderately malnourished on admission. The corresponding figure from MNA was 79% malnourished or at risk of malnutrition. Both tools indicated that anthropometric values and serum proteins were significantly lower in residents classified as being malnourished (P < 0.05). Sensitivity in detecting PEM was in SGA 0.93 and in MNA 0.96 and specificity was 0.61 and 0.26, respectively. Using regression analysis, weight index and serum albumin were the best objective nutritional parameters in predicting the SGA- and MNA classifications. Item 'muscle wasting' in SGA and 'self-experienced health status' in MNA showed most predictive power concerning the odds of being assessed as malnourished.Conclusions: SGA was shown to be the more useful tool in detecting residents with established malnutrition and MNA in detecting residents who need preventive nutritional measures.
