ResearchOriginal ResearchDietary Supplementation in Children with Autism Spectrum Disorders: Common, Insufficient, and Excessive
Section snippets
Sample
Children aged 2 to 11 years with ASD were recruited from five participating AS ATN sites between 2009 and 2011.1 AS ATN is a network funded by Autism Speaks to promote research and a standard of care regarding health conditions associated with ASD. All children entering or previously enrolled in the AS ATN who met the age requirement and consumed food by mouth were eligible for participation in this study. The five participating AS ATN sites in this study were Cincinnati Children’s Hospital,
Study Cohort
A total of 1418 children with ASD were eligible for the study based on age, ASD diagnosis, and enrollment at a participating AS ATN site, of whom 368 consented to the study. The proportion enrolling did not differ by age, sex, or ethnicity, but African Americans and mixed-race children were less likely to enroll. Of those who enrolled in this study, 292 completed 3-DFRs with the following distribution among DRI age- and sex-specific groups: 74 (26%) boys or girls aged 2 to 3 years, 177 (61%)
Discussion
This is the first article to examine micronutrient intake from both food and supplements using current nutrition research methods in a large, well-characterized sample of children with ASD. The effect of vitamin and mineral supplementation has previously been examined in the general pediatric population,3, 5 revealing that supplementation often does not correct for micronutrient inadequacies and can lead to excessive intake. In this study, similar results were found in children with ASD who
Conclusions
MVM supplements are the most common nutritional supplements given to children to ensure nutrient adequacy. However, most MVM supplements do not provide sufficient amounts of the micronutrients typically consumed in inadequate amounts by children with and without ASD. Instead, they often provide more of the micronutrients already consumed in sufficient amounts. This can lead to excessive intake that may place children at risk for adverse effects. Two of the micronutrients of greatest concern in
