Proportion of the Population Above and Below 40 nmol/L Serum 25-Hydroxyvitamin D Concentrations and Cumulative Distribution of Serum 25-Hydroxyvitamin D Concentrations: United States and Canada

The data in this appendix are provided for the readers of this report and were not reviewed by the committee.

For the United States (Table I-1 and Figures I-1 through I-8), the tables and figures for serum 25-hydroxyvitamin D (25OHD) concentrations are from analyses conducted in August 2010 by the National Center for Health Statistics, U.S. Centers for Disease Control and Prevention and based on the National Health and Nutrition Examination Survey (NHANES) 2003–2006.

For Canada (Table I-2 and Figures I-9 through I-14), the tables and figures for serum 25OHD concentrations are from analyses conducted in August 2010 by Statistics Canada and based on the Canadian Health Measures Survey (CHMS), Cycle 1, 2007–2009.
