Malnutrition is common in community-dwelling older adults and is associated with poor outcomes including hospitalization and mortality. Recently, a 6-question short form mini nutritional assessment (SF-MNA) was validated for rapid nutrition screening. Ideally, nutrition screening could be performed by individuals or their caregivers prior to or during an outpatient clinical visit, thus allowing for the ongoing monitoring of nutritional status among older adults.
We compared the SF-MNA administered by a healthcare professional (HCP) to a 6-item self-administered screening tool (Self-MNA) in 463 community dwelling older adults who gave informed consent. The population was 60% women with a mean age of 76.8±6.8 years. The HCP was blinded to the results of the Self-MNA questionnaire.
Using the SF-MNA, 27% of subjects were malnourished, 38% were at risk, and 35% had normal nutrition status. The agreement between the Self-MNA and the SF-MNA was 99% (Self-MNA sensitivity 99%, specificity 98%, false negative rate 1%, false positive rate 2%) for identifying Malnourished subjects and 83% (sensitivity 89%, specificity 77%, false negative rate 11%, false positive rate 23%) for identifying At Risk of Malnutrition compared to the MNA-SF administered by a HCP.
We found that the Self-MNA demonstrates sufficient inter-rater reliability for use in nutrition screening among community-dwelling older adults. Further validation studies and the possible impact of language translation should be pursued.
营养不良在社区居住的老年人中很常见，与不良结局相关，包括住院和死亡。最近，一种 6 问简短营养评估表（SF-MNA）被验证可用于快速营养筛查。理想情况下，营养筛查可以在门诊就诊前或就诊期间由个人或其护理人员进行，从而可以持续监测老年人的营养状况。
我们在 463 名知情同意的社区居住的老年人中比较了由医疗保健专业人员（HCP）进行的 SF-MNA 和 6 项自我管理的筛查工具（Self-MNA）。该人群中 60%为女性，平均年龄为 76.8±6.8 岁。HCP 对 Self-MNA 问卷的结果不知情。
使用 SF-MNA，27%的受试者存在营养不良，38%存在营养风险，35%的受试者营养状况正常。Self-MNA 和 SF-MNA 之间的一致性为 99%（Self-MNA 敏感性 99%，特异性 98%，假阴性率 1%，假阳性率 2%），用于识别营养不良的受试者，而 83%（敏感性 89%，特异性 77%，假阴性率 11%，假阳性率 23%）用于识别与 HCP 管理的 MNA-SF 相比存在营养风险的受试者。
我们发现 Self-MNA 对于社区居住的老年人的营养筛查具有足够的评分者间可靠性。应进一步进行验证研究和可能的语言翻译影响研究。
