The Role of Occupational Therapy in Managing Food Selectivity of Children with Autism Spectrum Disorder: A Scoping Review

Eating disorder in children: Impact on quality of life, with a spotlight on autism spectrum disorder

Eating behavior, which includes eating habits and preferences, frequency of eating, and other features related to diet, is a major characteristic not only of a person's nutritional status, but also of health in general. In recent years, the prevalence of eating disorders in children has tended to increase; they also require cross-system approaches in diagnosis by a variety of specialists and correction requires appropriate selection of optimal methods. Maladaptive eating attitudes formed at an early age can contribute to the formation of eating disorders, which can lead to or worsen various neuropsychiatric diseases, digestive diseases, and other related conditions. In children with autism spectrum disorder (ASD), eating disorders often appear earlier than other major symptoms of the condition. However, the clinical manifestations of eating disorders in children with ASD are varied and differ in severity and duration, whereas these disorders in neurotypical children might present as short-lived and may not lead to serious consequences. Nevertheless, cases of progressive eating disorders accompanied by a child presenting as under- or overweight and/or with macronutrient and micronutrient deficiencies cannot be excluded. Given the high prevalence of eating disorders in children, many researchers have highlighted the lack of a valid and universally accepted instruments to assess atypical eating behaviors in this population. Therefore, in this review, we wanted to highlight the problems and causes of eating disorders in children, and also to analyze the existing approaches to the validation of these problems, taking into account the existing behavioral features in children with ASD.

Autism Spectrum Disorder and Eating Problems: The Imbalance of Gut Microbiota and the Gut-Brain Axis Hypothesis

This review explores the complexities of autism spectrum disorder (ASD), primarily focusing on the significant eating challenges faced by children and adolescents with this neurodevelopmental condition. It is common for individuals with ASD to exhibit heightened sensitivity to various sensory aspects of food such as taste, texture, smell, and visual appeal, leading to restricted and less diverse diets. These dietary limitations are believed to contribute to an imbalance in the gut microbiota. This review elaborates on how these eating problems, coupled with the distinctive characteristics of ASD, might be influenced by and, in turn, influence the gut-brain axis, a bidirectional communication system between the gastrointestinal tract and the brain. This discussion aims to shed light on the multifaceted interactions and potential implications of diet, gut health, and neurological development and function in children and adolescents with ASD.

Role of gastrointestinal health in managing children with autism spectrum disorder

Children with autism spectrum disorders (ASD) or autism are more prone to gastrointestinal (GI) disorders than the general population. These disorders can significantly affect their health, learning, and development due to various factors such as genetics, environment, and behavior. The causes of GI disorders in children with ASD can include gut dysbiosis, immune dysfunction, food sensitivities, digestive enzyme deficiencies, and sensory processing differences. Many studies suggest that numerous children with ASD experience GI problems, and effective management is crucial. Diagnosing autism is typically done through genetic, neurological, functional, and behavioral assessments and observations, while GI tests are not consistently reliable. Some GI tests may increase the risk of developing ASD or exacerbating symptoms. Addressing GI issues in individuals with ASD can improve their overall well-being, leading to better behavior, cognitive function, and educational abilities. Proper management can improve digestion, nutrient absorption, and appetite by relieving physical discomfort and pain. Alleviating GI symptoms can improve sleep patterns, increase energy levels, and contribute to a general sense of well-being, ultimately leading to a better quality of life for the individual and improved family dynamics. The primary goal of GI interventions is to improve nutritional status, reduce symptom severity, promote a balanced mood, and increase patient independence.

Picky eating in children: Current clinical trends, practices, and observations within the Australian health-care context

BACKGROUND/AIM

Childhood picky eating occurs when there is limited intake or variety of food and/or unwillingness to try new foods. Within research settings, standardised assessments are used to describe picky eating behaviours in children. However, little is known about assessment practices of occupational therapists. Similarly, occupational therapy interventions for picky eating in the literature focus on; providing strategies for parents, and working with the child on self-feeding skills. Despite this, interventions and strategies utilised by occupational therapists in clinical practice within an Australian health-care context are unknown. This study examines Australian health professionals' observations of picky eating behaviours, the use of childhood picky eating assessments and interventions, and differences between occupational therapists and other professionals.

METHODS

Health professionals (n = 179) were recruited through professional organisations, such as Occupational Therapy Australia. Participants completed an online survey between March and May 2021. Independent variables were reported using descriptive statistics, with logistic regression used to consider differences between occupational therapists and other health professionals. Conventional content analysis was used to analyse responses to open-ended questions.

RESULTS

The final sample included 109 eligible participants, with an average of 8.5 years working with picky eaters. Results indicated picky eating behaviours aligned with those reported in the literature. Participants relied on clinical observations and workplace designed assessments. The most common interventions were education, coaching, and the sequential oral sensory approach to feeding. Occupational therapy participants were significantly more likely than other health professional participants to report always using coaching and education.

CONCLUSION

Although few health professionals used standardised or validated assessments, the use of education and coaching by occupational therapists aligned with the literature. Results highlight the need for more rigorous investigation to determine the sensitivity of current assessments to differentiate between clinical and typical picky eating, and the effectiveness of interventions for childhood picky eating.
