title: Vitamin D status: United States, 2001-2006.
abstract: The Institute of Medicine (IOM) recently released new dietary reference intakes for calcium and vitamin D. The IOM defined four categories of vitamin D status based on serum 25-hydroxyvitamin D (25OHD): (i) risk of deficiency, (ii) risk of inadequacy, (iii) sufficiency, and (iv) above which there may be reason for concern. This brief presents the most recent national data on vitamin D status in the U.S. population based on these IOM categories. Results are presented by age, sex, race and ethnicity, and, for women, by pregnancy and lactation status.
