Vitamin D levels hit their lowest levels in early spring, not in winter as previously thought.
A study of 24,000 people in New South Wales revealed that vitamin D deficiency is also affecting more Australians, and lasting longer.
Since current testing guidelines don’t address the need to take seasonal variation into account, researchers are calling for a testing guideline review. Supplement regimes also need to be reviewed because vitamin D deficiency also plays a factor in diseases such as diabetes and cancer.

I would have thought that the researchers would have wanted to look for at-risk groups in our socio-economic-religeous groups straight up. It doesn't take much thought to find a group in our current society which covers up not juat against the sun, but also against the view of the general public. Surely, this could be a major issue to those people!
