BRONX, N.Y.—Seven out of 10 U.S. children have low levels of vitamin D, raising their risk of bone and heart disease, according to a study of more than 6,000 children by researchers at Albert Einstein College of Medicine of Yeshiva University. The striking findings suggest vitamin D deficiency could place millions of children at risk for high blood pressure and other risk factors for heart disease. The study was published in the online version of Pediatrics.
