Vitamin D Supplements may Help Overcome Osteoporosis and Fractures in Children
Decreased bone strength characterises Osteoporosis. Skeletal fragility is enhanced in this condition and hence greater are the risks of acquiring fractures. More than 300 million people in India suffer osteoporosis. A low bone density is one of the most important predisposing factors for osteoporotic fractures. A diagnosis of osteoporosis is most commonly made by measuring the Bone mineral density (BMD). Building bone density in children prevents osteoporosis in later life.
Vitamin D is essential for skeletal maintenance. It enhances calcium absorption; reduces losses of calcium from the body and promotes calcium deposition into bone. Researches embarked on a quest to find if supercharging levels of vitamin D in healthy children encouraged their bones to lay down greater amounts of calcium. Theoretically this could prevent them from developing osteoporosis on aging.
Existing literature was searched for; details from randomised controlled trials were picked up and analysed. The results were published in Cochrane Database of Systematic Reviews 2010, Issue 10.
Vitamin D supplementation had no statistically significant effects on bone density at any site in healthy children. There was, however, some indication that children who had low levels of vitamin D in their blood might benefit from supplementation, says the study leader Dr Tania Winzenberg, from the Menzies Research Institute Tasmania.
Healthy children with normal vitamin D levels do not benefit from vitamin D supplements. Vitamin D supplements can bring no improvement in bone density at the hip, lumbar spine, forearm or in the body as a whole in these healthy children.
What we now require are detailed studies to find out whether supplements are of any utility in vitamin D deficient children.
In brief this study indicates that a low bone density is one of the most important predisposing factors for osteoporotic fractures. Healthy children with normal vitamin D levels do not benefit from vitamin D supplements in terms of BMD. Vitamin D supplements can bring no improvement in bone density at the hip, lumbar spine, forearm or in the body as a whole in these healthy children.
