Background: Food selectivity has been documented in children and is more prevalent in children with autism spectrum disorder (ASD). This can create feeding difficulties that may present as restricted food intake, texture based food selectivity, food refusal, and/or repetitive food choices. Objective: To describe food selectivity in obese adolescent with ASD and suggests directions for future research. Methods: Previous research assessed the effects of video game playing on obese adolescents with ASD utilizing a single subject multiple baseline design. Over 12 weeks, the participant played inactive (6 weeks) and active video games (6 weeks) on the Wii console. Physiological data (weight, height, waist-to-hip ratio, tricep skinfold) were evaluated weekly at home. Participants logged food intake each week during all phases (baseline, inactive video gaming, and active video gaming). Foods were grouped into the following categories: fruits, vegetables, proteins, starches, juices and other sweetened non-dairy drinks, and dairy. Results: Similar to previous research, participants preferred starches to other categories of food (50-75% of food intake). Proteins were the second most chosen food group. Fruits and vegetables were comprised less than 5% of the participants’ diet. Conclusions: Although numerous studies have examined food selectivity, none have assessed it in adolescents exclusively. This study describes food selectivity in obese adolescents and provides direction for future research.
