Overview
Vitamin D deficiency is common worldwide, and the incidence is increasing in the recent years. 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. [1]

|---|---|---|---|---|---|
| Total | Non-Hispanic White | Non-Hispanic Black | Mexican American | Others | |
| Percent | 18.8 (16.3–21.5) | 10.6 (8.9–12.4) | 53.6 (48.9–58.2) | 27.2 (22.8–32.0) | 27.2 (23.2–31.7) |
- However, data from the National Health and Nutrition Examination Surveys (NHANES) in 2001-2006 shows that one-quarter were at risk of vitamin D inadequacy (serum 25OHD 30–49 nmol/L), and 8% were at risk of vitamin D deficiency (serum 25OHD less than 30 nmol/L). [2]

- In both sexes, the prevalence was lowest in children aged 1–8 years. Risk of deficiency increased significantly with age until age 30 in males and age 18 in females, after which it did not change significantly with age. [2]

- There is a slightly higher prevalence of vitamin D deficiency in female than male. According to the National Health and Nutrition Examination Surveys (NHANES) in 2001-2006, the season-adjusted prevalence at risk of deficiency by age ranged from 1% to 8% in males and 1% to 12% in females. [2]
