Korean Youth with Comorbid Allergic Disease and Obesity Show Heightened Psychological Distress.

Objective: To explore psychological distress in Korean adolescents having allergic disease comorbid with obesity.

Study Design: A total of 703 869 adolescents who completed the Korean Youth Risk Behavior Web-based Survey between 2007 and 2016 were analyzed. Participants were divided into 4 groups-healthy control, allergic disease only, obesity only, and comorbidity of allergic disease and obesity-and compared them to determine whether they showed differences in mental health.

Results: Adolescents with both atopic dermatitis and obesity had significantly greater odds of experiencing unhappiness (OR, 1.17), stress (OR, 1.32), and suicidal ideation (OR, 1.25) than those without both conditions. The same was true of adolescents with obesity and allergic rhinitis (OR, 1.21, 1.37, and 1.27, respectively) or bronchial asthma (OR, 1.37, 1.39, and 1.37). The comorbidity groups also showed significantly greater odds of stress and suicidal ideation than the allergic disease-only (atopic dermatitis with obesity, 1.21 and 1.15, respectively; allergic rhinitis with obesity, 1.11 and 1.09; bronchial asthma with obesity, 1.17 and 1.14) and obesity-only groups (atopic dermatitis with obesity, 1.13 and 1.09; allergic rhinitis with obesity, 1.18 and 1.10; bronchial asthma with obesity, 1.18 and 1.21).

Conclusions: Allergic disease and obesity negatively and additively influence mental health in adolescents.
