To determine how well the Mini Nutritional Assessment (MNA) Short Form (MNA-SF) performed as a nutritional screening tool when calf circumference replaced body mass index (BMI) as the included anthropometric measurement.
A total of 100 patients ≥70 years were recruited from a Geriatric Evaluation and Management Unit.
Mean age of patients was 85.2 (6.1) years. By the full MNA, 40% of patients were malnourished. The MNA correlated highly with both of its short-form versions (r = 0.87 and r = 0.90 for the BMI and calf circumference versions, respectively). Both MNA-SF versions also showed high accuracy in identifying malnutrition (auROC values >0.89).
The MNA-SF is a rapid and accurate way to screen for malnutrition in hospitalised older adults. Substitution of BMI measurement with the time-efficient calf circumference measurement maintained MNA-SF accuracy. It is recommended that calf circumference measurement be used for nutritional screening by MNA-SF in a hospital setting.
确定当用小腿围度取代体重指数（BMI）作为纳入的人体测量指标时，微型营养评定法简表（MNA-SF）作为营养筛查工具的表现如何。
从老年评估与管理单元招募了100名年龄≥70岁的患者。
患者的平均年龄为85.2（6.1）岁。通过完整的MNA评定，40%的患者存在营养不良。MNA与其两个简表版本均高度相关（BMI版本和小腿围度版本的r值分别为0.87和0.90）。两个MNA-SF版本在识别营养不良方面也显示出较高的准确性（受试者工作特征曲线下面积值>0.89）。
MNA-SF是筛查住院老年人营养不良的一种快速且准确的方法。用省时的小腿围度测量取代BMI测量可保持MNA-SF的准确性。建议在医院环境中使用小腿围度测量进行MNA-SF营养筛查。
