Sleep Disturbances and Dietary Habits in Autism: A Comparative Analysis

Area of Science:

• Neurodevelopmental Disorders
• Nutritional Science
• Sleep Medicine

Background:

• Children and adolescents with autism spectrum disorder (ASD) often experience sleep disturbances.
• Dietary patterns in ASD populations are not fully understood in relation to sleep quality.

Purpose of the Study:

• To compare dietary patterns and sleep quality in children and adolescents with and without ASD.
• To investigate the relationship between diet and sleep quality in individuals with ASD.
• To identify potential dietary interventions for improving sleep and well-being in ASD.

Main Methods:

• Cross-sectional case-control study with 158 ASD participants and 77 controls (ages 6-17) in Spain.
• Dietary patterns assessed via food frequency questionnaire.
• Sleep quality measured using the Children's Sleep Habits Questionnaire (CSHQ-SP) and Pittsburgh Sleep Quality Index (PSQI).
• Statistical analyses included non-parametric tests and Spearman's correlation.

Main Results:

• ASD group showed higher sugar intake and lower fruit/vegetable consumption than controls.
• Poorer sleep quality (increased sleep latency, parasomnias, daytime dysfunction) observed in the ASD group.
• Positive association between fruit/vegetable intake and better sleep quality in ASD children.
• Complex, potentially risky, relationship between sugar intake and sleep quality in ASD adolescents.

Conclusions:

• Significant differences in diet and sleep quality exist between ASD and non-ASD youth.
• Dietary interventions focusing on increased fruit/vegetable intake and reduced sugar may improve sleep in ASD.
• Addressing dietary habits is a potential strategy to enhance sleep and overall well-being in individuals with ASD.
