Association between vitamin D and sway・falls among Japanese frail elderly living in the community and intervention study for nursing care prevention

我们提出了一个包括运动和营养改善相结合的老年人护理预防方案。摄入不同食物的人身体机能较高。此外，与摇摆和跌倒相关的血清维生素D （25(OH)D）水平在90%以上的体弱老年人中缺乏。在课程结束时，25(OH)D水平大于67.5nmol/L的个体在肌肉力量/平衡/行走能力方面有更大的改善。相比之下，25(OH)D水平低于47.5nmol/L的个体的体质没有得到改善。大于67.5nmol/l似乎对日本虚弱老年人的下肢力量更有利。

We proposed a nursing care prevention program including exercise and nutrition improvement together into frail elderly. A physical function was high in the individual who did various food intakes. Furthermore, the serum level of vitamins D (25(OH)D) associated with sway and falls was short for 90% above of the frail elderly. Greater improvements in muscular strength/balance/walking ability for the individuals with 25(OH)D levels greater than 67.5nmol/L were observed at the end of class. In contrast, the individuals with 25(OH)D levels lower than 47.5nmol/L did not improve their physical fitness. Greater than 67.5nmol/l appears to be preferable for lower extremity strength in Japanese frail elderly.
