Impact of eating habits and nutritional status on children with autism spectrum disorder

Objectives: Obesity is common among children with Autism Spectrum Disorder (ASD). They suffer more feeding problems than children with normal developmental milestones. Several kinds of diet are recommended for children with ASD. This study determines the frequency of eating disorders and obesity among such children. We investigate the predisposing factors of eating disorders and examine the effects of consumed food on autism scores.Methods: In this single-centre, cross-sectional study, 46 children with ASD aged between 2 and 10 years were included. Anthropometric measurements were recorded and Brief Autism Mealtime Behavior Inventory (BAMBI), Autism Behavior Checklist (ABC), and Food Frequency Questionnaire (FFQ) forms were filled in by their parents.Results: The rates of being overweight and obese were 10.9% and 28.3%, respectively. Food selectivity was observed in 84.8% of the children, and BAMBI food refusal scores were significantly higher for those aged between 2 and 5 years (p = 0.03). Autism scores and consumption of milk, yoghurt, oily seeds, rice/pasta, and fruits (p < 0.05) were significantly correlated. There were also significant differences between these scores and the frequency of consuming eggs, legumes, and other cereals (p < 0.05).Conclusion: Obesity was more common in children with ASD than typically developed children. Despite the high rate of food selectivity, our findings confirmed that food selectivity could be considered independent of obesity. Further, the diet of patients with ASD must include more fruits, yogurt, eggs, legumes, other cereals, less milk, and less rice/pasta.
