Abstract

Objectives: The aim of this review was to assess the relationship between sensory processing and a range of eating behaviours in autism across the lifespan.
Methods: Five electronic databases of published and unpublished quantitative studies were systematically searched, evaluated for risk of bias and synthesized according to identified eating outcomes.
Results: Across 25 studies, there was consistent evidence of a relationship between sensory processing and a range of eating behaviours. There was early evidence for the particular role of taste/smell sensitivities, as well as hypersensitivities, although future research is needed looking at different sensory patterns and modalities. There was a lack of research looking at this relationship in adolescence and adulthood, as well as a lack of exploring the relationship is disordered eating or feeding outcomes.
Discussion: Study findings are discussed in relation to implications for sensory-based eating and feeding interventions and the development of eating or feeding disorders. Methodological and conceptual limitations are discussed and suggestions for future research are made to address these limitations. A broader investigation of multi-sensory issues and clearly defined eating behaviours, including disordered eating in clinically diagnosed samples, will allow for a more comprehensive and robust understanding of the relationship between sensory processing and eating behaviours in autism.
