Kids and Vitamin D Deficiency. ââââââRosemont, IL, October 17, 2012 â A startling increase in the frequency of severe vitamin D deficiency is being reported in the U.S. and other countries. This severe deficiency can have a devastating impact on a childâs bone strength, the United States Bone and Joint Initiative (USBJI) says.
Vitamin D deficiency is often a silent disease. By definition, rickets occurs in children whose growth plates have not fused. These children are often found to have started walking late or prefer to sit down for prolonged periods. In adults, vitamin D deficiency results in osteomalacia, which presents as a poorly mineralized skeletal matrix. Adults in these cases can experience chronic muscle aches and pains. Vitamin D deficiency is the most common cause of nutritional rickets. Rare genetic forms of rickets occur because of defects in vitamin D metabolism.
