Background: sarcopenia is a disease associated with muscle changes during aging, and its detection remains a challenge outside specialized clinical units. Objective: to evaluate the utility of the Mini-Nutritional Assessment (MNA) in detecting sarcopenia in institutionalized older persons. Materials and methods: we conducted a cross-sectional study in adults aged 55 and older from Puebla. We administered both the short form (SF) and the complete form (LF) of the MNA. We diagnosed sarcopenia according to EWGSOP2 criteria. We plotted the points obtained from MNA-SF and MNA on a ROC curve. We evaluated the odds ratio (OR) for presenting sarcopenia based on the recommended cutoff points using logistic regression models adjusted for age and sex. Results: the study included 162 participants, with 64.1 % of them being women, and the mean age was 69.8 years (SD: 5). The mean scores of MNA-SF and MNA-LF were 12.17 (SD: 1.78), and 25.1 (SD: 2.83), respectively. The prevalence of sarcopenia was 20.4 %. The AUC of MNA-SF was 0.68 (95 % CI: 0.58-0.78), and for MNA-LF, 0.60 (95 % CI: 0.49-0.71). The OR for presenting sarcopenia with MNA-SF < 12 was OR = 2.87 (95 % CI: 1.31-6.29) and, after adjustment for age and sex, OR = 2.47 (95 % CI: 1.10-5.54). Conclusions: according to AUC, MNA-SF may help detect sarcopenia in institutionalized older persons, while MNA-LF may have reduced utility in practice.
肌肉减少症是一种与衰老过程中肌肉变化相关的疾病，在专业临床机构之外，其检测仍然是一项挑战。目的：评估微型营养评定法（MNA）在检测机构养老老年人肌肉减少症方面的效用。材料与方法：我们对普埃布拉55岁及以上的成年人进行了一项横断面研究。我们同时使用了MNA的简表（SF）和完整版（LF）。我们根据欧洲老年人肌肉减少症工作组（EWGSOP2）标准诊断肌肉减少症。我们将从MNA-SF和MNA获得的分数绘制在ROC曲线上。我们使用根据年龄和性别调整的逻辑回归模型，基于推荐的截断点评估出现肌肉减少症的比值比（OR）。结果：该研究纳入了162名参与者，其中64.1%为女性，平均年龄为69.8岁（标准差：5）。MNA-SF和MNA-LF的平均得分分别为12.17（标准差：1.78）和25.1（标准差：2.83）。肌肉减少症的患病率为20.4%。MNA-SF的曲线下面积（AUC）为0.68（95%置信区间：0.58 - 0.78），MNA-LF的AUC为0.60（95%置信区间：0.49 - 0.71）。MNA-SF < 12时出现肌肉减少症的OR = 2.87（95%置信区间：1.31 - 6.29），在调整年龄和性别后，OR = 2.47（95%置信区间：1.10 - 5.54）。结论：根据AUC，MNA-SF可能有助于检测机构养老老年人的肌肉减少症，而MNA-LF在实际应用中的效用可能较低。
