Dietary Patterns and Body Mass Index in Children with Autism and Typically Developing Children.

To determine whether dietary patterns (juice and sweetened non-dairy beverages, fruits, vegetables, fruits & vegetables, snack foods, and kid's meals) and associations between dietary patterns and body mass index (BMI) differed between 53 children with autism spectrum disorders (ASD) and 58 typically developing children, ages 3 to 11, multivariate regression models including interaction terms were used. Children with ASD were found to consume significantly more daily servings of sweetened beverages (2.6 versus 1.7, p=0.03) and snack foods (4.0 versus 3.0, p=0.01) and significantly fewer daily servings of fruits and vegetables (3.1 versus 4.4, p=0.006) than typically developing children. There was no evidence of statistical interaction between any of the dietary patterns and BMI z-score with autism status. Among all children, fruits and vegetables (p=0.004) and fruits alone (p=0.005) were positively associated with BMI z-score in our multivariate models. Children with ASD consume more energy-dense foods than typically developing children; however, in our sample, only fruits and vegetables were positively associated with BMI z-score.

Food selectivity in children with autism spectrum disorders and typically developing children.

OBJECTIVES: To define food selectivity and compare indices of food selectivity among children with autism spectrum disorders (ASDs) and typically developing children, and to assess the impact of food selectivity on nutrient adequacy. STUDY DESIGN: Food selectivity was operationalized to include food refusal, limited food repertoire, and high-frequency single food intake using a modified food frequency questionnaire and a 3-day food record. Food selectivity was compared between 53 children with ASDs and 58 typically developing children age 3-11 years. Nutrient adequacy was assessed relative to the dietary reference intakes. RESULTS: The children with ASDs exhibited more food refusal than typically developing children (41.7% of foods offered vs 18.9% of foods offered; P <.0001). They also had a more limited food repertoire (19.0 foods vs 22.5 foods; P <.001). Only 4 children with ASDs and 1 typically developing child demonstrated high-frequency single food intake. Children with a more limited food repertoire had inadequate intake of a greater number of nutrients. CONCLUSIONS: Our findings suggest that food selectivity is more common in children with ASDs than in typically developing children, and that a limited food repertoire may be associated with nutrient inadequacies.

Behavioral Health in Developmental Disabilities: A Comprehensive Program of Nutrition, Exercise, and Weight Reduction.

We review the literature on the prevalence and conditions resulting in overweight and obesity in people with intellectual disability (ID), followed by obesity treatment research with typically developing children and adaptations for children with ID. In addition to proposing directions for future research and practice, we report a comprehensive randomized control trial (RCT) of family-based behavioral intervention targeting weight loss among adolescents with Down syndrome.
