OBJECTIVE: Little epidemiological evidence exists on rumination disorder behavior (RB) and pica behavior (PB). We examined prevalence of RB and PB and presence of comorbid feeding/eating disorder symptoms among school-aged children.
METHOD: In elementary schools in Switzerland, 1,430 children (54.0% female) ages 7-13 completed the Eating Disorder Examination-Questionnaire for children (ChEDE-Q) and the Eating Disturbances in Youth Questionnaire (EDY-Q).
RESULTS: EDY-Q behavior frequency showed 9.7% reported RB only, 10.0% reported PB only, and 3.1% reported RB + PB (≥1 on 0-6 Likert scale). At a clinical cut-off score of ≥ 4, 1.7% had RB only, 3.8% had PB only, and 1.1% had RB + PB. Avoidant/restrictive food intake disorder symptoms were most common in those with RB + PB, and more common in those with RB or PB than those without. The degree of eating disorder symptoms (by ChEDE-Q) over the past 28 days were similar among those with RB, PB, or RB + PB, but less common in those without RB or PB.
DISCUSSION: RB and PB were commonly reported in our sample of school-aged children, even at a potential clinically significant cut-off. Our findings also suggest that the degree of eating disorder symptom comorbidity is similar between those with RB and PB.
