Picky Eating in Childhood: Associations With Obsessive-Compulsive Symptoms.

ABSTRACT

OBJECTIVE: To test whether childhood picky eating (PE)-a behavior previously linked to many forms of psychopathology-is specifically associated with symptoms of obsessive-compulsive disorder (OCD). METHODS: We investigated the relationship between PE and symptoms of several forms of psychopathology in two separate observational samples a sample of 110 children (5 and 6 years old) and a sample of 210 children (8 and 9 years old) drawn from a longitudinal study. In each sample, regression models based on psychiatric symptoms or diagnoses were used to assess the specificity of PE associations while accounting for cooccurring symptoms or comorbidities. RESULTS: Although bivariate associations emerged between PE and multiple forms of psychopathology, multivariate analyses revealed these associations were driven by a strong and specific association between PE and symptoms of OCD in both samples. Moreover, PE among 8- and 9-year-olds in the longitudinal study predicted emergence of additional later psychopathology, specifically attention-deficit/hyperactivity disorder (ADHD). CONCLUSIONS: Findings suggest that PE, an easily identifiable clinical presentation, is also a specific marker for obsessive-compulsive symptomatology in school-age children and may impart risk for ADHD later in childhood.
