Brief Report: Decreased Bone Health in Children with Autism Spectrum Disorder and Avoidant Restrictive Food Intake Disorder.

PURPOSE: Children with autism spectrum disorder (ASD) and food selectivity are at increased risk for nutritional deficiencies which could affect bone health.

METHODS

We report on four male patients with ASD and avoidant restrictive food intake disorder (ARFID) with significant bone conditions including rickets, vertebral compression fractures, osteopenia, and slipped capital femoral epiphyses.

RESULTS

Each patient was at risk for at least one nutritional deficiency. Two out of four patients had deficiencies in Vitamins A, B12, E, and zinc. Calcium and Vitamin D deficiency were noted in all four. Two out of four patients with Vitamin D deficiency developed rickets.

CONCLUSION

Provisional evidence suggests that children with ASD and ARFID are at elevated risk for serious adverse bone health outcomes.
