Overview
Vitamin D deficiency is common worldwide and the incidence of it is increasing. In the US, vitamin D deficiency is more prevalent among non-white ethnic groups. The prevalence is different based on different laboratory methods and the cut-off for the vitamin D deficiency.
Epidemiology and Demographics
Prevalence
According to Institute of Medicine (IOM), based on the National Health and Nutrition Examination Survey (NHANES) 2003–2006, there is an overall 18.8% prevalence of serum 25OHD concentrations below 40 nmol/L in the US.
