An analysis of blood samples from more than 10,400 children showed that those with vitamin D levels of less than 30 nanograms per milliliter had an almost twofold increased risk of having anemia compared with those who had normal levels of the vitamin. Although more black children than white children in the study had anemia, researchers found that black children's odds of developing anemia did not increase until their vitamin D levels were much lower compared with their white counterparts. The findings were published on the website of the Journal of Pediatrics.
