To know the prevalence of risk of malnutrition in community-dwelling elderly (defined as aged >65) attended in a Primary Care Center, to find the main factors associated to malnutrition risk and to evaluate the Mini Nutritional Assessment Questionnaire (MNA) MNA Short Form vs. MNA Full Test.
Design: Cross-Sectional study.
Primary Care Center.
337 participants visited in the Community Care Center. Mini Nutritional Assessment Questionnaire (MNA) was applied; sociodemographic and Health variables were collected as well as functional evaluation tests (Short Portable Mental Status Questionnaire and Lawton & Brody Instrumental Activities of Daily Living Scale). Clinical history information was taken from the Medical Records. Using MNA Full Test (MNA-FT) as the gold standard, sensitivity, specificity and predictive values of MNA Short Form (MNA-SF) were evaluated.
prevalence according MNA-FT was 0.6% for malnutrition and 7.7% for malnutrition risk. No gender differences were found. The average age was higher in the population with malnutrition or at risk for malnutrition (p=0.016). Significant association of malnutrition with having carer (p<0.0001) or being more dependent (p<0.0001) was found. MNA-SF showed an acceptable sensitivity (67.9%) and good specificity (92.6%).
Compared with other studies this data showed a low prevalence of malnutrition risk in community-living elderly using the MNA test. It is recommended to use the MNA-FT in order to avoid under diagnosing malnutrition with MNA-SF.
了解在初级保健中心就诊的社区老年人（定义为年龄> 65 岁）的营养不良风险流行情况，找出与营养不良风险相关的主要因素，并评估简易营养评估量表（MNA）短表与 MNA 全量表。
设计：横断面研究。
初级保健中心。
337 名在社区护理中心就诊的参与者。应用简易营养评估量表（MNA）；收集社会人口统计学和健康变量以及功能评估测试（简短便携精神状态问卷和 Lawton 和 Brody 日常生活活动工具量表）。从病历中获取临床病史信息。以 MNA 全量表（MNA-FT）为金标准，评估 MNA 短表（MNA-SF）的灵敏度、特异性和预测值。
根据 MNA-FT，营养不良的患病率为 0.6%，营养不良风险的患病率为 7.7%。未发现性别差异。营养不良或有营养不良风险的人群平均年龄较高（p=0.016）。营养不良与有照顾者（p<0.0001）或依赖性更强（p<0.0001）显著相关。MNA-SF 显示出可接受的灵敏度（67.9%）和良好的特异性（92.6%）。
与其他研究相比，本研究使用 MNA 测试显示社区居住的老年人营养不良风险的患病率较低。建议使用 MNA-FT，以避免使用 MNA-SF 低估营养不良的诊断。
