Abstract : EVIDENCE‐BASED ANSWER : The overall prevalence of vitamin D deficiency (25‐hydroxyvitamin D levels <30 nmol/L) in the United States is 8.1% and is slightly higher in females (9.9%) than males (6.3%). Mexican Americans (11%), and non‐Hispanic blacks (31%) have a higher prevalence than whites (3.6%). In adolescents, the prevalence is 8.5% to 24.1% using 30 to 37.5 nmol/L cutoffs. Breastfed infants not receiving vitamin supplements have a prevalence of 64%. The data on children are inconsistent, with rates ranging from 0.7% to 40% (SOR: C, cross‐sectional studies of diseaseoriented data).
