血清25-羟维生素D与老年人跌倒骨折关系的研究进展
[摘要]我国已进入人口老龄化快速发展阶段，跌倒是老年人常见的意外事件，跌倒后伴有骨折者可达12%。维生素D（Vit D）不仅可以调节人体钙磷代谢和维持机体的骨密度，而且对老年人的平衡力和肌力也会产生重要影响;低Vit D老年人群补充Vit D可以改善其平衡能力及肌力，从而减少跌倒的发生。血清25-羟维生素D[25（OH）D]是临床上可供检测的能够反映机体Vit D代谢情况及营养状况的最佳指标，本文对25（OH）D与老年人平衡能力、肌力和跌倒的关系进行综述。

[Abstract] China has entered a rapid developing stage of population aging. Falls， 12% of which are accompanied by fractures， are common accidents for the elderly. Vitamin D （Vit D） can not only regulate calcium and phosphorus metabolism and maintain bone mineral density， but also have an important impact on the balance and muscle strength of the elderly. Vit D supplementation may improve the balance and muscle strength of the elderly people who lack Vit D， thus reducing the occurrence of falls. Serum 25-hydroxy vitamin D （25[OH]D） is the best clinical indicator to reflect the metabolism and nutritional status of Vit D. This article reviews the relationship between 25（OH） D and balance ability， muscle strength and falls in the elderly.
