Tip #45: Your Child and Vitamin D.

About 70 percent of U.S. children have low levels of vitamin D, which puts them at higher risk for bone and heart disease, researchers said today.

“We expected the prevalence of vitamin D deficiency would be high, but the magnitude of the problem nationwide was shocking,” said Dr. Juhi Kumar of Children’s Hospital at Montefiore Medical Center.  The researchers analyzed data on more than 6,000 children, ages 1 to 21, collected by the National Health and Nutrition Examination Survey 2001-2004.   The researchers found that 9 percent, or 7.6 million children across the country, were vitamin D deficient and another 61 percent, or 50.8 million, were vitamin D insufficient.

 The American Academy of Pediatrics, which recently updated its vitamin D guidelines, now recommends that infants, children, and teens should take 400 IU per day in supplement form.  Supplements are especially important for children living in northerly regions where the sun may be too weak to maintain healthy vitamin D levels. Supplements are also critical for infants who are breast-fed, the researchers said in a statement today. Breast milk contains relatively little vitamin D, while formula is fortified with the vitamin.

    Circulating 25-Hydroxyvitamin D Levels in Fully Breastfed Infants on Oral Vitamin D Supplementation this paper shows us that from one month old 400iu/daily is sufficient for a baby 10lbs weight. The same ration, 100iu per 2.5lbs or 1000iu/daily per 25lbs weight generally achieves a 25(OH)D that slightly more than covers daily vitamin D needs and permits a small store of vitamin D3 in tissues. Levels around 60ng/ml are necessary to enable human breast milk to flow replete with D3.
    These researchers found that 6400iu/daily/D3 was necessary at latitude 32N.
