“…As discussed earlier, the children's reactions must indeed be understood as an effect of the whole familiarization procedure, including both the most general aspects of our intervention and the tailormade adaptations we used to respond to the neurodiverse needs of this population and to best fit the individual functioning of each child. The individual adaptations raise questions, however, about the sampling procedure in populations known to present a certain heterogeneity and/or consisting of subgroups, which is the case for people with ASD (Brunsdon and Happé, 2014;Georgiades et al, 2013;Morales-Hidalgo et al, 2018;Wiggins et al, 2017). Given the limited data available to characterize the participants, the sample would have benefited from being selected from a given subgroup in order to be more homogeneous.…”

This study assessed whether olfactory familiarization can render food odors more pleasant, and consequently food more attractive, to children with autism spectrum disorder. Participants were first presented with a series of food odors (session 1). Then, they were familiarized on four occasions (time window: 5 weeks) with one of the two most neutral odors (the other neutral odor was used as control) (session 2). In session 3, participants smelled the entire series of odors again. Both verbal and facial responses were compared from session 1 to session 3. After session 3, the children were presented with two identical foods (one containing the familiarized odor and one the control odor) and were asked to choose between these foods. Results revealed (1) a specific increase in positive emotions for the familiarized odor and (2) that 68% of the children chose the food associated with the “familiarized odor” (children who chose the “familiarized odor” food exhibited significantly more sensory particularities). These findings suggest that it is possible to modulate olfactory emotions and expand the dietary repertoire of children with autism spectrum disorder. Application of this paradigm may enable innovative prospects for food education in autism.

“…In Spain, a two-phase cross-sectional study in the framework of EPINED project was performed in Tarragona (year of study performance not specified), yielding prevalence estimates of 15.5/1000 and 10.0/1000 in the age classes 3-5 years and 10-12 years, respectively [22]. At about the same time, a study was performed using data from the Catalan Public Health Service on children aged 2 to 17 years.…”

Epidemiology of Autism Spectrum Disorders: A Review of Worldwide Prevalence Estimates Since 2014

The prevalence of Autism Spectrum Disorder (ASD) has increased dramatically in recent decades, supporting the claim of an autism epidemic. Systematic monitoring of ASD allows estimating prevalence and identifying potential sources of variation over time and geographical areas. At present, ASD prevalence estimates are available worldwide, coming either from surveillance systems using existing health and educational databases or from population studies specifically performed. In the present article, we present a review of the ASD prevalence estimates published since 2014. Data confirm a high variability in prevalence across the world, likely due to methodological differences in case detection, and the consistent increase of prevalence estimates within each geographical area.

“…In the past few years, research has recognised ASD as a continuum of severity ranging from subclinical autistic traits or symptoms to full syndrome (Constantino & Charman, 2016; Morales-Hidalgo et al, 2017). The prevalence has increased in recent years, with ASD being diagnosed in 1 of 53/54 children (Maenner et al, 2020; Morales-Hidalgo et al, 2021) and subdiagnostic autistic symptoms requiring support in 3%–4% of the child population (Jussila et al, 2020; Morales-Hidalgo et al, 2018).…”

This article assesses nutritional intake and adequacy in children with autism spectrum disorder (ASD), subdiagnostic autistic symptoms and children with typical development (TD). In total, 77 children diagnosed with ASD, 40 with subdiagnostic autistic symptoms and 333 children with TD were assessed. A validated food frequency questionnaire was used. Very few nutritional differences were found between ASD and TD groups. Preschool children with ASD and subdiagnostic autistic symptoms had slightly lower intake of monounsaturated fatty acids (MUFA), vitamin D and vitamin B12, and primary school children with ASD and subdiagnostic autistic symptoms had slightly higher intake of protein, cholesterol, thiamine and niacin, and a higher percentage of obesity than children with TD. All samples had an unbalanced energy intake (high in added sugars, fats and saturated fatty acids (SFAs); extremely inadequate intake (80%–100%) of vitamins D and E; high intake (50%–80%) of fibre, b-carotene (except preschool children with TD), calcium (except preschool children) and magnesium). The fact that differences between diagnoses are scarce may be related to the low level of ASD severity in this school sample. Lay abstract Children with autism spectrum disorder (ASD) have a fivefold elevated risk of developing eating problems, which predisposes them to nutritional deficiencies. This study assesses nutritional intake and adequacy in children with ASD, subdiagnostic autistic symptoms and typically developing (TD) children. Preschool children with ASD and subdiagnostic symptoms had slightly lower intake of monounsaturated fatty acids (MUFA), vitamin D and vitamin B12. Primary school children with ASD and subdiagnostic symptoms had slightly higher intake of protein, cholesterol, thiamine and niacin, and a higher percentage of obesity than children with TD. All children had a high intake in sugars, fats and saturated fatty acids; a very highly inadequate intake of vitamins (vitamins D and E), fibre, b-carotene, calcium and magnesium; and a moderately inadequate intake of vitamin C, folate and iron. However, although all children need nutrition advice, children with ASD and subdiagnostic autistic symptoms had a poorer quality diet than those with TD.
