Objective: The purpose of this study was to evaluate the type and frequency of psychopathological disorders observed in obese children and adolescents. We also looked for a correlation between psychic disorders in the obese children, the degree of obesity and paternal psychopathology.
Patients and methods: The study group included 84 obese children and adolescents aged 5 to 16 years (mean age 10.9 +/- 2.8 years). There were 55 girls and 29 boys. The z-score expressing deviation from the ideal body mass index (IMC) varied from +2 to +10.6 (mean 4 + 1.9). Psychopathological disorders observed in these obese patients were compared in children and adolescents with insulin-dependent diabetes mellitus. The standard diagnostic interview (K-SADS PL) and self-administered questionnaires (Sielberger STAIC-Trait for anxiety and CDI for depression in children or CBCL or GHQ for their parents) were also used to evaluate psychic disorders.
Results: More than half of the obese children (47 out of 84) had a DSM-IV diagnosis, often involving anxiety (n = 28). The rate of internalized and externalized psychopathological disorders (measured by STAIC-Trait and CBCL) was higher in the obese children than in the diabetics. The children's psychopathological disorders were more marked if their parents were perturbed, particularly when their mother had an internalized disorder. No correlation was found between the degree obesity and psychopathological disorders in the obese children and adolescents.
Conclusion: Our findings show the frequency of mental disorders in obese children and point out the importance of parental psychopathology. This underlines the usefulness of a pedopsychiatric approach implicating the entire family for therapeutic management of these patients.
