Internalizing and externalizing problems in obese children and adolescents: associations with daily salivary cortisol concentrations

摘要

OBJECTIVE: Pediatric obesity commonly co-exists with emotional and behavioral disorders, while disturbed cortisol concentrations have been reported in both obese and chronically stressed individuals with anxiety and/or depression. We investigated the prevalence of internalizing and externalizing problems, reported by both parents and children, in a clinical population of obese children (OC) compared to normal-weight children. We examined the role of cortisol as a potential mediator between obesity and such problems. DESIGN: We compared 110 obese with 31 normal-weight children. The Greek version of the child behavior checklist (CBCL) and the youth self-report (YSR) were used and salivary cortisol was determined serially five times a day. RESULTS: T-scores of internalizing problems (anxiety/depression, social withdrawal, somatic complains) reported by both children (49.3±12.3 vs. 43.2±9.1) and mothers (60.6±11.3 vs. 50.6±10.4) were significantly higher (p=0.03 and p
