Following on from another thread about some countries "not" having Vit D deficiency, I thought I'd do a quick google scholar and see what I could find.

Australia & New Zealand
Between 11-100% greatly varied due to season, age and ethnicity
Paper

UK
About 35% of 4-18 year olds
Paper

USA
21-49% of sample 6-18 year olds
Paper

Iran
86% of 9-12 year olds
Paper

India
10-35% of 10-18 year olds

And then they all started to blend but basically Malaysia and Singapore for kids is pretty Vit D safe.

So the "not in my back yard" approach needs to be rethought. Especially when

Careful you don't miss it and treat them with an orthotic.

 

Interesting. I'm currently working with an adolescent female athlete with a history of two spinal stress fractures and now a suspected stress fracture in her 2nd metatarsal. When retrieving a history, the mother said that the patient had been diagnosed a couple of years ago with vitamin D deficiency. At this time her GP had insisted that there was no need to test for this, but the mother had persisted only for the diagnosis to be made. Seems I was the first person to suggest the potential link between her history of stress fracture and Vit D deficiency :morning:. Just goes to show...

 

Thanks Cylie.

I'm actually quite surprised that the prevalence in the UK is not much higher!

 

So was I, but there was quite a few papers so it may have been higher, especially in the Black & Indian population which I didn't see. The lighter the skin, the less sun that is actually needed and I've seen what happens with the UK sun worship. I think there is a bit of a culture as well, that babies are parked in the sunshine in their prams, kids are pushed out to play regardless. Where as in Aus was are so sunsmart and have gone so far the other way due to skin cancer.

Don't forget though in the really young ones, there is an impact from extended breast feeding or formula. If the maternal health system is excellent in pushing out the monitoring during pre/post natal that will impact the baby/toddler.

Lastly obesity is also huge factor. The 100% quoted in the Polynesian South Island NZ population. So there is the dark skin, obese and cold factors to content with.
