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.
Osteomalacia is a disease in adults that results from vitamin D deficiency. Characteristics of this disease are softening of the bones, leading to bending of the spine, bowing of the legs, proximal muscle weakness, bone fragility, and increased risk for fractures.itamin D deficiency causes osteomalacia (called rickets when it occurs in children). Use of vitamin D in children with normal vitamin D levels does not appear to improve bone density. Beyond that, low serum vitamin D levels have been associated with falls, and low bone mineral density.
