OBJECTIVE
We designed this study, to evaluate the interaction (relation) between vitamin B12 and folic acid levels and length of hospital stay in elderly inpatients.
METHODS
In this cross-sectional study, the Mini Nutritional Assessment-Short Form (MNA-SF) test was used to evaluate nutritional status of 615 (239 men, 376 female; mean age 72.89 ± 8.93 y) inpatients of a university hospital. Length of stay and blood samples in elderly inpatients were evaluated.
RESULTS
Only 33.8% of the patients were classified as having an adequate nutritional status; 44.3% had a risk of malnutrition, and 21.8% were classified as malnourished. Low MNA-SF score was related to length of stay, but vitamin B12 and folic acid were not related to risk of malnutrition and length of stay.
CONCLUSION
MNA-SF score is associated with length of stay; however, vitamin B12 level, per se, is not associated with length of hospital stay in elderly inpatients.
目的
本研究旨在评估维生素 B12 和叶酸水平与老年住院患者住院时间的相互作用（关系）。
方法
在这项横断面研究中，我们使用微型营养评估-简短表格（MNA-SF）测试评估了一所大学医院 615 名（239 名男性，376 名女性；平均年龄 72.89±8.93 岁）住院患者的营养状况。评估了老年住院患者的住院时间和血液样本。
结果
只有 33.8%的患者被归类为具有充足的营养状况；44.3%存在营养不良风险，21.8%被归类为营养不良。MNA-SF 评分较低与住院时间有关，但维生素 B12 和叶酸与营养不良风险和住院时间无关。
结论
MNA-SF 评分与住院时间有关；然而，维生素 B12 水平本身与老年住院患者的住院时间无关。
