Abstract Pediatric vitamin and mineral supplements are thought to be used commonly in the United States, but details of their use are lacking. Using data from the Slone Survey (a cross-sectional national random-digit-dial medication use survey), this study sought to define the prevalence and patterns of use of supplemental vitamins, fluoride, and iron among US children younger than 12 years of age. Primary statistical analyses involved descriptive statistics and calculation of weighted prevalence of use estimates with 95% confidence intervals. Between February 1998 and April 2007, there were 2,857 children 0 to 11 years of age enrolled from the 48 contiguous United States with weighted prevalence of use of vitamins, iron, and fluoride as the primary outcome. The response rate to the survey was 61%. Overall, 23.1% of children had used a vitamin, fluoride, or iron supplement in the 7 days before the interview, with use being highest among 2- to 5-year-olds. Almost all vitamins and most fluoride and iron were taken in the form of multicomponent products. The most commonly taken specific vitamins were C, D, B-12, B-6, and B-2, each by >20% of children. Overall, 3.3% of study participants took supplemental fluoride and 9.7% took supplemental iron. In conclusion, this study found that almost one-quarter of US children younger than 12 years of age, and 30% of 2-year-olds, use supplemental vitamins, fluoride, and iron in a given week. These data should be combined with what is known about the need for pediatric supplementation with vitamins, fluoride, and iron to help clinicians and policy makers counsel parents about the optimal use of these products.
