The Relationship Between Avoidant/Restrictive Food Intake Disorder in Children Diagnosed with Autism Spectrum Disorder and Orthorexia Nervosa in Their Mothers

The aim is to examine the relationship between Avoidant/Restrictive Food Intake Disorder (ARFID) symptoms and sensory sensitivities in children diagnosed with Autism Spectrum Disorder (ASD), as well as the relationship between maternal orthorexia nervosa (ON) and ARFID, and to identify the factors influencing ARFID. The symptom severity of 104 children was assessed using the Childhood Autism Rating Scale (CARS), maternal ON symptoms with ORTO-11, ARFID symptoms with the Nine-Item Avoidant/Restrictive Food Intake Disorder Screening Tool (NIAS), and sensory sensitivities with the Eyuboglu Sensory Reactivity Scale (ESRS). Multiple regression analyzed predictors of NIAS scores, and moderator analysis examined whether ORTO-11 moderated the ESRS-NIAS relationship. ON was present in 58% of the mothers. Mothers with ON had significantly higher total NIAS scores and NIAS Fear subscale scores. A positive and statistically significant relationship was found between the CARS scores and the hyporeactivity and sensory-seeking subscales of the ESRS scale. When NIAS was taken as the dependent variable, a significant regression relationship was found between CARS-9 and ORTO-11. However, ORTO-11 does not play a moderating role in the effect of ESRS on NIAS. ARFID symptoms are predicted by maternal ON symptoms and CARS-9 scores in children. We emphasize the importance of evaluating the eating attitudes and food perspectives of caregivers when atypical eating behaviors are identified in the clinical follow-up of children diagnosed with ASD. Since the study was conducted solely with mothers', further research is needed to examine the effects of ON symptoms in fathers and other caregivers.
