Features of feeding difficulty in children with Autism Spectrum Disorder

Abstract Parents of children with Autism Spectrum Disorders (ASD) commonly report concerns regarding feeding difficulties and poor nutrition. Feeding difficulties, in the form of undesirable mealtime behaviours and/or skill deficits, can cause parental concern and impact on family dynamics. Poor nutrition can have an impact on development and health outcomes. The purpose of this paper was to review recent research regarding feeding difficulties in children with ASD, in order to describe: (1) the most frequently reported undesirable mealtime behaviours and skill deficits; and (2) dietary intake and weight patterns as markers of nutrition. While the ASD population is a somewhat heterogeneous group, this literature review of 44 research studies identified a number of common issues for these children. Restricted dietary variety, food neophobia, food refusal, limiting diet based on texture, and a propensity towards being overweight were frequently reported. Gaining a better understanding of the common features of feeding difficulties experienced by children with ASD will assist in directing intervention studies. Findings from such studies have the potential to enhance developmental and nutritional outcomes for this group. Well-designed longitudinal research would be valuable in monitoring the impact of feeding difficulties for these children as they age.

Efficacy of interventions to improve feeding difficulties in children with autism spectrum disorders: a systematic review and meta‐analysis

BACKGROUND Feeding difficulties are relatively common in children with autism spectrum disorders (ASD), but current evidence for their treatment is limited. This review systematically identifies, reviews and analyses the evidence for intervention in young children with ASD and feeding difficulties. METHODS A comprehensive search strategy was used to identify studies from January 2000 to October 2013. Studies were included if they described interventions where the goal was to increase desirable eating behaviours or decrease undesirable eating behaviours using an experimental design, including single-subject research methodology. Studies were reviewed for descriptive information, and research quality was appraised using a formal checklist. Individual study findings were compared using Improvement Rate Difference (IRD), a method for calculating effect size in single-subject research. RESULTS Overall, 23 papers were included. All studies reviewed had five or fewer participants, and reported on operant conditioning style intervention approaches, where the child is prompted to perform an action, and receives a contingent response. Where quality measures were not met, it was primarily due to lack of detail provided for the purposes of replication, or failure to meet social validity criteria. Meta-analysis indicated a medium-large effect size [mean = 0.69, 95% confidence interval (CI) 0.60 to 0.79] when the outcome measured was an increase in desirable behaviours (e.g. consuming food), but a small-negligible effect size (mean = 0.39, 95% CI 0.18 to 0.60) when the outcome measured was a decrease in undesirable mealtime behaviours (e.g. tantrums). Only a small proportion of studies reported outcomes in terms of increased dietary variety rather than volume of food consumed. CONCLUSIONS The reviewed literature consisted primarily of low-level evidence. Favourable intervention outcomes were observed in terms of increasing volume, but not necessarily variety of foods consumed in young children with ASD and feeding difficulties. Further research in the form of prospective randomized trials to further demonstrate experimental effect in this area is required.

A survey of practice for clinicians working with children with autism spectrum disorders and feeding difficulties

Abstract The aim of this study was to document information from allied health clinicians about children on their caseload with autism spectrum disorders and feeding difficulties. An electronic survey was disseminated to clinicians working with this group around Australia, where 150 responses were returned and 96 were able to be analysed. Variability in responses was observed for service delivery models, frequency of input, referral reasons, and intervention choices. The majority of respondents identified limited-to-average knowledge of feeding therapy options for this population. Clinician confidence was significantly correlated with perceived therapy success. Results of the survey suggest a need for clinical guidelines in the area to direct practice. Low levels of clinician confidence and perceived therapy success also highlight a need for ongoing research and training.

Use of parent report to screen for feeding difficulties in young children

This study aimed to collect data on Australian children with regard to feeding difficulties using a standardised questionnaire, compare these data to international data collected using the same tool, assess the short‐term reliability of this tool and determine the sensitivity and specificity of this tool in detecting feeding difficulties.

Clinical Characteristics of 2 Groups of Children With Feeding Difficulties

Objectives: The primary aim of this study was to describe and compare the clinical characteristics of 2 groups of children presenting to a feeding clinic: children with autism spectrum disorder (ASD) and children with a nonmedically complex history (NMC). A secondary aim was to compare participants according to the degree of oral motor impairment, presence of oral hypersensitivity, and clinically significant parent stress. Methods: Children with feeding difficulties ages between 2 and 6 years were recruited. Prospective data were collected on dietary intake, general development, mealtime behaviors, oral motor skills, oral sensory processing, and parental stress via parent questionnaire and clinical assessment. Results: In total, 68 children (ASD = 33 and NMC = 35) participated in the study. Both groups presented with a large number of difficult mealtime behaviors. Although stress was elevated in both groups, parents of children in the ASD group reported significantly higher stress levels than those with children in the NMC group (mean difference 27.3 on a percentile scale, 95% confidence interval [CI] 15.5–39.2, P < 0.01). Across both groups, the majority of children presented with mild-to-moderate oral motor impairments (ASD = 28, 85%; NMC = 28, 80%). Children with heightened oral sensory sensitivity consumed significantly fewer unprocessed fruits and vegetables (mean difference 3.3 foods, 95% CI 1.3–5.3, P < 0.01), and their parents reported a significantly greater frequency of difficult mealtime behaviors (mean difference 5.8 behaviors, 95% CI 3.4–8.1, P < 0.01). Conclusions: Features of feeding difficulty presented similarly across the ASD and NMC groups in this study. Oral motor impairment, oral sensory sensitivity, and parental stress should not be overlooked in the management of children with feeding difficulties, regardless of etiology.

Dysphagia progression and feeding skills following pediatric alkali ingestion injury: two case reports

Abstract Purpose: There is limited information regarding the nature of dysphagia and feeding difficulties following alkali ingestion injury to inform multidisciplinary intervention. The aim was to describe the history and nature of chronic dysphagia and feeding difficulties in two children following severe alkali ingestion injury. Methods: Medical records, primary caregiver report, and clinical assessment were used to compile detailed case histories and assess current dysphagia and feeding skills. Results: Both cases demonstrated heterogeneous oral motor and feeding outcomes, including delayed oral motor skills, restricted dietary variety, and difficult mealtime behaviors that contributed to protracted recovery of age-appropriate PO intake. Both children required ongoing diet and/or fluid modification and supplemental non-PO feeding via gastrostomy at the time of review, that is, 2-year post-injury. Conclusions: Recovery from dysphagia post-alkali ingestion is protracted and complex. Dysphagia, delayed oral motor skills, and difficult mealtime behaviors may persist secondary to ingestion injury and its associated complications. These cases highlight the importance of considering early referral for feeding assessment and intervention to assist children and families with recovery. Progression through safe and effective oral (per os, PO) intake is needed, as well as provision of support for primary caregivers. Implications for Rehabilitation Pediatric chemical ingestion injury can cause long-term dysphagia and long-term feeding difficulties Initial injury severity does not reliably correlate with eventuating level of aerodigestive impairment. Clinical and instrumental assessment is required to monitor swallow function to enable commencement of targeted rehabilitation when appropriate. Early involvement of a feeding therapist is recommended to minimize the long-term effects on oral motor skill development, progression to age-appropriate diet, and provision of family-centered care.

Intervention for feeding difficulties in children with a complex medical history: a randomized clinical trial

Objective: This study aimed to compare outcomes of different multidisciplinary feeding therapy approaches in children with feeding difficulties. Methods: Children aged 2 to 6 years with feeding difficulties and a medically complex history (MC) were recruited. Children with feeding difficulties and a nonmedically complex history (NMC) were included as a comparison group. Participants attended a clinical assessment, and eligible participants were randomized to receive targeted feeding intervention incorporating either operant conditioning or systematic desensitization. Parents could elect to receive intervention in an intensive (10 sessions in a week) or weekly (10 sessions during 10 weeks) format. Both groups received immersive parent training. A review was completed 3 months post-intervention. Results: In total, 98 participants were eligible to participate (MC, n = 43; NMC, n = 55). Data from 20 children from the MC group (47%) and 41 children from the NMC group (75%) were included in the final analysis. Clinically significant improvements were observed following both arms of therapy, consistent with previous research. Parents of children in the MC arm were significantly more likely to elect for intensive intervention than weekly (MC = 12/20, 60%; 12/41, 29%; P = 0.02). Conclusions: Both therapy protocols were considered clinically effective. The difference in attrition rates between the etiological groups suggests primary differences in how service delivery should be managed. Progress for the medically complex child may be slower while medical issues are stabilized, or while the focus for parents shifts to other developmental areas. In planning services for a medically complex group, therefore, it is essential that consideration be given to medical and family needs.
