Association Between Atopic Dermatitis and Suicidal Behaviors in North Korean Adolescent Defectors From 2011 to 2019

Objective To evaluate the association between atopic dermatitis (AD) and suicidal behaviors in adolescent defectors among residents who escaped from North Korean (adolescent defectors, n=423) and adolescents with South Korean parents (Korean adolescents,Methods The study used data from the Korea Youth Risk Behavior Survey conducted from 2011 to 2019. Differences in general characteristics, health behaviors, suicidal ideation, suicide plans, suicide attempts, and AD between adolescent defectors and Korean adolescents were examined. Multiple logistic regression analysis was used to determine the association between AD and suicidal behaviors.Results The adolescent defectors group had lower AD (16.3% vs. 24.2%), poorer subjective health (10% vs. 6%), smoked more (47% vs. 18%), drank more (60% vs. 43%), lived with family less frequently (56% vs. 96%), and were more than twice as likely to have depression (42% vs. 27%), suicidal ideation (30% vs. 14%), a suicide plan (23% vs. 5%), or have made a prior suicide attempt (19% vs. 3%) compared with the Korean adolescent group (p<0.001). The adjusted odds ratio for the adolescent defectors group compared to the Korean adolescent group was 1.66 for suicidal ideation, 3.59 for suicide plans, and 4.34 for suicide attempts (p<0.001). AD was found to be associated with suicide plans and attempts in adolescent defectors and associated with suicidal ideation in Korean adolescents.Conclusion AD was significantly associated with suicide plans and suicidal attempts among adolescent defectors and suicidal ideation in Korean adolescents, based on a random sample of middle- and high-school students.
