This study examined how comorbid anxiety and depression to eating disorders in children affect the relationship between stress in children and their emotional eating behaviours. We sampled 1 120 children from 60 public primary schools across Taiwan (female = 42.5%; age range = 11 to 12 years old). The children completed measures of mood and eating disorders, as well as stress experience. Following simple mediation and a moderated mediation analysis, results indicated that anxiety and depression scores significantly mediate the relationship between stress and emotional eating scores. Specifically, those children self-reporting higher anxiety and depression scores also had higher stress experience and emotional eating compared to those with lower anxiety and depression scores. These results suggest that while an eating disorder is associated with stress experience and emotional eating, the co-occurrence of anxiety and depression increases the risk for emotional eating.
