A nutritional survey performed in 46 elderly long-term surgical patients in an orthopedic ward showed that, although a sufficient hospital diet was served, the intakes of vitamin B12 were borderline, while the intakes of folate were inadequate inmost patients. Low energy intake combined with a high consumption of titbits in bedridden patients was assumed to be responsible for this malnourishment.
对某骨科病房46名老年长期手术患者进行的一项营养调查显示，尽管提供了充足的医院饮食，但维生素B12的摄入量处于临界水平，而大多数患者叶酸摄入量不足。卧床患者能量摄入低且卧床时零食消耗量高被认为是造成这种营养不良的原因。
