abstract="Although an increase in vitamin D has a small effect on bone mineral density, it has an influence on fracture prevention. This may be explained by a mechanism of improvement of bone strength that does not necessarily depend on bone mineral density. The level of serum 25 (OH) D is low in hip fracture patients compared with non-fracture controls, which suggests that a background of vitamin D insufficiency may be involved in hip fracture. Vitamin D acts on skeletal muscle and nerve cells, and it has been reported that this has an effect on fall prevention. Furthermore, recent reports suggest a role of vitamin D in cognitive function and in other tissues not involving bone.<p /> <p>Language: ja</p>",
