Abstract

OBJECTIVE: High prevalence of vitamin D deficiency was previously reported in children with Autism Spectrum Disorder (ASD), but little is known about the efficacy of vitamin D3 treatment in ASD, although data from pilot studies seem promising. We hypothesized that serum vitamin D levels are reduced in ASD and correlate with the severity of disease. Also, we hypothesized that vitamin D3 treatment may be beneficial for a considerable portion of children with ASD. METHODS: In total, 215 children with ASD and 285 healthy control children were recruited in our study. Thirty seven of 215 ASD children received vitamin D3 treatment. The Autism Behaviour Checklist (ABC) and the Childhood Autism Rating Scale (CARS) were used to assess autism symptoms. High-performance liquid chromatography was used to assess the serum 25-hydroxyvitamin D [25(OH) D] level. Evaluations of ABC, CARS, and serum 25(OH) D levels were performed before and after 3 months of treatment. RESULTS: Serum levels of 25(OH) D were significantly lower in ASD children than typically developing children. Levels of serum 25(OH) D were negatively correlated with ABC total scores and language subscale scores. After vitamin D3 supplementation, symptom scores were significantly reduced on the CARS and ABC. In addition, the data also suggest that treatment effects were more pronounced in younger children with ASD. CONCLUSION: Vitamin D deficiency might contribute to the aetiology of ASD. Supplementation of vitamin D3, which is a safe and cost-effective form of treatment, may significantly improve the outcome of some children with ASD, especially younger children (identifier ChiCTR-CCC-13004498). CLINICAL TRIAL REGISTRATION: The trial 'Association of Polymorphisms of Vitamin D Metabolism-Related Genes With Autism and the Treatment of Autism with Vitamin D' has been registered at www.chictr.org/cn/proj/show.aspx? proj=6135 (identifier ChiCTR-CCC-13004498).

  • Feng et al. (2016) reported a higher proportion of ASD children having 25(OH)D concentrations <25 nmol/L (13% vs. 0%, p = 0.03) and <75 nmol/L (71% vs. 62%, p = 0.03) than healthy typically developing controls.

    “In a recent large study from China, Feng et al. (2016) reported higher proportion of ASD children having 25(OH)D concentrations <25 nmol/L (13% vs. 0%, p = 0.03) and <75 nmol/L (71% vs. 62%, p = 0.03) than healthy typically developing controls [117].”

  • 25(OH)D concentrations of those entering the Feng et al. study in April could be different from those entering September due to potentially limited sun exposure during winter months.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
