Professor Clarke describes a recent case:
"That‘s a month ago who was referred to me because of delayed walking. An infant was 15 months old and the legs were so bowed the child could not stand physically."
He acknowledges the balance parents have to strike, but is greatly concerned by the lifestyle changes pursued by some families.
"It's very difficult for parents because they're encouraged to apply sunscreen because of the dermatological consequences of not. But it would seem that that excess is too much for bone health and vitamin D. So they're shutting out the sunshine which is causing problems with their bones. Similarly children, and particularly adolescents, don't go out as much,there isn't as much school sport and when they do go out they tend to cover up."
Vitamin D is known as the sunshine vitamin because our skin can produce it from the sun's ultra-violet light. It helps control the amount of calcium we absorb and is important for the development of strong bones.
Without vitamin D, rickets can develop which then causes bones to soften. Usually a child's legs appear bowed as a result of rickets.
Four-year-old Toby Ault was diagnosed with an early onset rickets nine months ago after complaining that his legs hurt.
When his mother took Toby to the family doctor, he suspected it was a vitamin D deficiency and a blood test confirmed his suspicions.
For children like Toby, it seems that too much love and protection can have serious consequences for a child's health. |
