Abstract

Objective This study investigated the prevalence of feeding and eating disorders, and identified their correlates and comorbidities among children and adolescents. Method We used the nationally representative sample of the Iranian Children and Adolescents' Psychiatric disorders (IRCAP) survey, with 30,532 participants randomly selected by a multistage cluster sampling method. We employed the kiddie schedule for affective disorders and schizophrenia-present and lifetime version (K-SADS-PL) semi-structured face-to-face interview to screen for any psychiatric disorders, including feeding and eating disorders, and associated factors. We used multivariate binary logistic regression to analyze the data. Results Valid data from 27,111 participants were analyzed. The total prevalence of feeding and eating disorders among children and adolescents was 0.89 (0.81-1.10). In all types of feeding and eating disorders, the adjusted odds ratio was higher among girls (except binge-eating disorder) and older adolescents but was lower among rural residents. The most common psychiatric comorbidities observed in children and adolescents with feeding and eating disorders were obsessive-compulsive disorder (20.2%), agoraphobia (20.2%), depressive disorder (16.4%), social phobia (10.1%), oppositional defiant disorder (10.1%), generalized anxiety disorder (9.4%), attention deficit hyperactivity disorder (7.5%), and conduct disorder (5.7%), which were significantly more common compared to their peers without feeding and eating disorders. Discussion Older age, female gender and living in an urban area are predisposing factors in feeding and eating disorders (in binge-eating disorder, the male gender is a positive correlate). We suggest that future works pay attention to the role of gender, comorbidities and predisposing factors.
