RESUMO
Feeding problems represent a frequent concern reported by caregivers of children with autism spectrum disorders, and growing evidence suggests atypical patterns of intake may place this population at risk of nutritional and/or related medical issues, including chronic vitamin and mineral deficiencies, poor bone growth, and obesity. This combination of factors emphasizes a clear need to identify and disseminate evidence-based treatment of feeding problems associated with autism spectrum disorders. Behavioral intervention represents an effective treatment for chronic feeding concerns in this population; however, evidence has largely been established with trained therapists working in highly structured settings. This pilot study seeks to fill this gap in the literature by describing and evaluating the Autism MEAL Plan, a behaviorally based parent-training curriculum to address feeding problems associated with autism spectrum disorders. We assessed the feasibility of the intervention in terms of program content and study protocol (e.g. recruitment and retention of participants, assessment procedures), as well as efficacy in terms of changes in feeding behaviors. A total of 10 families participated in the treatment condition, and the program was evaluated using a waitlist control design (n = 9), representing the first randomized-control study of a feeding intervention in autism spectrum disorders. Results provide provisional support regarding the utility of the program, including high social validity, parent perception of effectiveness, and reduced levels of caregiver stress following intervention. Implications, limitations, and future directions for this line of research are discussed.

We conducted a comprehensive review and meta-analysis of research regarding feeding problems and nutrient status among children with autism spectrum disorders (ASD). The systematic search yielded 17 prospective studies involving a comparison group. Using rigorous meta-analysis techniques, we calculated the standardized mean difference (SMD) with standard error and corresponding odds ratio (OR) with 95 % confidence intervals (CI). Results indicated children with ASD experienced significantly more feeding problems versus peers, with an overall SMD of 0.89 (0.08) and a corresponding OR of 5.11, 95 % CI 3.74-6.97. Nutrient analyses indicated significantly lower intake of calcium (SMD: -0.65 [0.29]; OR: 0.31, 95 % CI 0.11-0.85) and protein (SMD: -0.58 [0.25]; OR: 0.35, 95 % CI: 0.14-0.56) in ASD. Future research must address critical questions regarding the cause, long-term impact, and remediation of atypical feeding in this population.

The current study examined the effects of bite placement with a flipped versus upright spoon on expulsion and mouth clean (product measure of swallowing) in the treatment of 3 children diagnosed with a pediatric feeding disorder and oral-motor deficits. For all 3 participants, extinction in the form of nonremoval of the spoon led to improvements in inappropriate mealtime behavior and acceptance of bites; however, re-presentation did not reduce expulsion or improve mouth clean. Results showed a lower level of expulsion and higher percentage of mouth clean during flipped spoon presentations and re-presentations for all participants. Findings from follow-up analyses supported transitioning back to an upright spoon in all 3 cases, although the time required for this to occur differed across participants.

The current study examined the rate of expulsions and mouth cleans across 3 presentation methods (upright spoon, flipped spoon, Nuk brush) for a 3-year-old girl with a feeding disorder. The participant expelled all bites presented on an upright spoon. Results showed reduced rates of expulsions and increased mouth cleans during the flipped spoon and Nuk brush presentation methods.

A systematic review of the literature regarding treatment of pediatric feeding disorders was conducted. Articles in peer-reviewed scientific journals (1970-2010) evaluating treatment of severe food refusal or selectivity were identified. Studies demonstrating strict experimental control were selected and analyzed. Forty-eight single-case research studies reporting outcomes for 96 participants were included in the review. Most children presented with complex medical and developmental concerns and were treated at multidisciplinary feeding disorders programs. All studies involved behavioral intervention; no well-controlled studies evaluating feeding interventions by other theoretical perspectives or clinical disciplines met inclusion criteria. Results indicated that behavioral intervention was associated with significant improvements in feeding behavior. Clinical and research implications are discussed, including movement toward the identification of key behavioral antecedents and consequences that promote appropriate mealtime performance, as well as the need to better document outcomes beyond behavioral improvements, such as changes in anthropometric parameters, generalization of treatment gains to caregivers, and improvements in nutritional status.
