摘要

Purpose

Eating and dietary challenges are common among children with autism, but their associations with clinical symptoms remain unclear. This study aims to describe dietary issues, including nutritional problems and overexposures to food additives in autistic children, and their associations with clinical symptoms.

Methods

This case-control study involved 836 children (469 with autism and 367 without autism; mean age = 8.3 years) profiled on autistic symptoms, eating behaviors, and dietary patterns with parent-reported questionnaires. Nutritional insufficiencies, dietary quality and food additives exposures were compared using regression models adjusted for age and sex. Multivariate logistics or linear regression models were used to identify clinical symptoms that predict dietary issues, with mediation analyses examining eating behaviors’ roles.

Results

Autistic children had lower protein intake, more vitamin and mineral insufficiencies, higher exposure to food additives, and poorer diet quality. They consumed fewer fruits/vegetables and more animal-based fats, with 38.2% exceeding 125% of the Estimated Energy Requirement (vs. 22.9% controls), suggesting energy-dense, ultra-processed food preferences. Diminished food enjoyment and increased food fussiness mediated between low social motivation and nutritional insufficiencies, as well as poorer diet quality. Further, difficulties with food responsiveness and emotional eating patterns mediated between more restricted and repetitive behaviors and higher exposures to emulsifiers/thickeners.

Conclusion

Autistic children, especially those with severe core symptoms, are susceptible to multifaceted dietary issues such as preference for low-quality food and nutrient deficiencies. It is crucial to implement personalized treatment strategies that target their specific eating behaviors to effectively address dietary challenges.
