Relation between ARFID symptomatology and picky eating onset and duration

Area of Science:

• Pediatric Psychology
• Childhood Nutrition
• Eating Disorders

Background:

• Picky eating (PE) is common in early childhood but can persist, leading to health and psychosocial issues.
• Avoidant/restrictive food intake disorder (ARFID) involves restrictive eating with significant impairment.
• This study investigates the link between early childhood PE and ARFID symptoms.

Purpose of the Study:

• To examine the relationship between the onset and duration of picky eating (PE) in early childhood and avoidant/restrictive food intake disorder (ARFID) eating restrictions and symptoms.
• To identify if persistent PE beyond the normative period is associated with ARFID criteria.

Main Methods:

• A retrospective study involving 437 children aged 6-17.
• Parents completed surveys on child's eating behavior, including the Nine-item ARFID Screen (NIAS).
• Children were grouped by PE onset (before/after age 5) and duration: never, normative, persistent, and late-onset picky.

Main Results:

• Groups significantly differed in NIAS subscale and total scores (p < .05).
• Persistent picky eaters (PEs) showed higher NIAS-PE, NIAS-A, and NIAS-T scores than never or normative PEs (p < .05).
• Persistent PEs were significantly more likely to meet ARFID criteria compared to other groups.

Conclusions:

• Picky eating persisting beyond the normative period is associated with elevated ARFID symptoms.
• Persistent PE increases the risk of impairment from eating restrictions.
• Early identification and intervention for children with persistent PE are warranted due to ARFID-related health and psychosocial risks.
