Description

Background: Eating problems and in particular food selectivity is a condition that worsens a long-life disorder such as ASD, both on an individual level , both on family and social ones . Regarding factors that contribute to this eating behavior have been identified sensory atypia , rigid behaviors and behavioral problems , however the problem has not yet been fully clarified.

Objective: The study aims to:

1. evaluate the presence and characteristics of food selectivity, in a sample of preschool children with ASD, the impact of this on the child's height and weight growth, the possible correlation with gastrointestinal symptoms and with oro-motor skills; b) assess the correlation between food selectivity and the characteristics of ASD (sensory atypia, repetitive behaviors, level of severity of symptoms), the cognitive development/ability quotient, adaptive functioning and the presence of behavioral disorders; c) highlight the impact of food selectivity of ASD children on parental stress.These aims are relevant in order to identify possible future therapeutic interventions that rate both the child's needs and parents involvement.

Methods: children (2-6 years) diagnosed with ASD according to DSM-5 criteria at the IRCCS Stella Maris institute (Clinical Unit ASD Department), were enrolled in an observational, cross-sectional and multicentric study conducted by three different Italian clinical centers (IRCCS Stella Maris Foundation Pisa, Regional Center for Autism Spectrum Disorders - Verona, Observation Diagnostic Training Lab - Trento). This study received the approval of the Tuscany Regional Ethics Committee for the pediatric age (Meyer).

In detail, the study involves parents by administering an anamnestic interview regarding the medical history and development of the child, the rehabilitation and pharmacological intervention in progress; the collection of a video recording of two meals in a family context. Parents complete a series of questionnaires including Child Oral and Motor Proficiency Scale( ChOMPS ), Brief Autism Mealtime Behavior Inventory, (BAMBI) ; Sensory Profile 2( SP2); Child Behavior Checklist (CBCL) 1.5-5 or 6-18 ; Parenting Stress Index, (PSI); Food diary ; Autism-Spectrum Quotient Test (AQ) ); Gastrointestinal Symptom Severity Index (GISSI); Mac Arthur questionnaire . The study includes the evaluation of children' cognitive functioning through the administration of a psychometric/developmental test, the administration of a standardized test for the evaluation of socio-communicative skills (Autism Diagnostic Observation Schedule 2 Edition ) and the observation of a meal of the child at the institute. The study provides a database dedicated to the collection data obtained.

As regards the statistical analyses, the researchers want to examine subjects affected by food selectivity identified and compared with the remaining group. A clinical characterization of children with food selectivity will be defined to describe any differences in the sensory profile and in eating difficulties based on the characteristics of the ASD and the cognitive abilities of the children. Then the impact of the same eating difficulties will be evaluated on the child's adaptive and emotional difficulties and on parental stress index.
