The relationship of autistic traits to taste and olfactory processing in anorexia nervosa / Emma KINNAIRD in Molecular Autism, 11 (2020)
[article]
Titre : The relationship of autistic traits to taste and olfactory processing in anorexia nervosa Type de document : Texte imprimé et/ou numérique Auteurs : Emma KINNAIRD, Auteur ; Catherine STEWART, Auteur ; Kate TCHANTURIA, Auteur Article en page(s) : 25 p. Langues : Anglais (eng) Mots-clés : Anorexia nervosa Autism Eating disorders Olfaction Sensory Taste Index. décimale : PER Périodiques Résumé : BACKGROUND: There is a heightened prevalence of autism in anorexia nervosa (AN) compared to the general population. Autistic people with AN experience a longer illness duration and poorer treatment outcomes. Whether sensory differences in autism could contribute to altered taste and smell as a potential maintaining factor in AN is under-explored. The aim of this study was to explore whether autistic traits are associated with taste and olfaction differences in AN. METHODS: The study recruited n = 40 people with AN, and n = 40 healthy controls (HC). Smell sensitivity was measured using the Sniffin' Sticks test. Taste sensitivity was measured using taste strips. Participants self-rated their autistic traits using the Autism Spectrum Quotient. RESULTS: There were no significant differences on taste and olfactory outcomes between people with AN and HC. These findings did not change after controlling for the heightened levels of autistic traits in the AN group. No relationship between taste and smell outcomes and autistic traits were identified within the AN group. LIMITATIONS: The current study is not able to draw conclusions about taste and smell processing in co-occurring autism and AN as it only measured levels of autistic traits, rather than comparing people with and without an autism diagnosis. CONCLUSIONS: No significant associations between autistic traits and taste and smell processing in AN were identified. Future research should consider further exploring this area, including by comparing autistic women to women with AN.

Titre : A preliminary study of self-reported food selectivity in adolescents and young adults with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Emily S. KUSCHNER, Auteur ; Ian W. EISENBERG, Auteur ; Bako ORIONZI, Auteur ; W. Kyle SIMMONS, Auteur ; Lauren KENWORTHY, Auteur ; Alex MARTIN, Auteur ; Gregory L. WALLACE, Auteur Article en page(s) : p.53-59 Langues : Anglais (eng) Mots-clés : Autism Food Taste Sensory Adolescent Adult Index. décimale : PER Périodiques Résumé : Although it is well-established that picky eating is a common feature of early development in autism spectrum disorder (ASD), far less is known about food selectivity during adolescence and adulthood. Using portions of the Adult/Adolescent Sensory Profile, food selectivity self-ratings were obtained from 65 high-functioning adolescents/young adults with ASD and compared to those of 59 typically developing controls matched on age, IQ, and sex ratio. Individuals with ASD reported preferring familiar foods (food neophobia) and disliking foods with particular textures and strong flavors. Providing linkage to everyday behavior, parent ratings of daily living skills were lower among individuals with ASD and food neophobia than among those without food neophobia. Food selectivity continues to be an important issue for adolescents/young adults with ASD.
