Recent Vitamin D Data from NHANES: Variability, Trends, Deficiency and Sufficiency Rates, and Assay Compatibility Issues

Abstract

data, the order of mean 25OHD levels and vitamin D sufficiency rates by race/ethnicity was: non-Hispanic white (NHW) > Mexican American (MA) > non-Hispanic black (NHB) and sufficiency rate was as low as 2.8% for NHB 12-19 years old. The order of vitamin D deficiency rates by race/ethnicity was: NHB > MA > NHW and deficiency rate was as high as 17% for 20-64 years old NHB. Females had higher mean 25OHD levels than males except for age groups 6-11 and 12-19 years old. Females had higher vitamin D deficiency rates than males and the deficiency rate for females was as high as 4.5% for those aged 12-19 and 65+ years old. Females had higher sufficiency rates than males except for 6-11 years old and the sufficiency rate for females was as high as 47.2% for 65+ years old. Recent release of 25OHD data from NHANES for 2001-2006 was not found to be compatible with 2007-2010 NHANES data.
