1 in 5 U.S. kids found deficient in vitamin D

Chicago(AP) — At least 1 in 5 U.S. children ages 1 to 11 doesn’t get enough vitamin D and could be at risk for a variety of health problems including weak bones, the most recent national analysis suggests.

By a looser measure, almost 90 percent of black children that age and 80 percent of Latino kids could be vitamin D deficient – “astounding numbers” that should serve as a call to action, said Dr. Jonathan Mansbach, lead author of the new analysis and a researcher at Harvard Medical School and Children’s Hospital in Boston.

The deficiency is a concern because recent studies suggest the vitamin might help prevent infections, diabetes and some cancers.

The new analysis, released online today by the journal Pediatrics, is the first assessment of varying vitamin D levels in children ages 1 through 11. The study used data from a 2001-06 government health survey of almost 3,000 children who had blood tests measuring vitamin D.
