This study compared mental illnesses in patients with AD with those of patients with nonatopic eczema, urticaria, and psoriasis in Korea.Methods: A cross-sectional study design was used, analyzing data from the 2015 Korean National Health Insurance Research Database, a survey of 42,641 AD and 139,486 non-AD (nonatopic eczema, urticaria, and psoriasis) patients (103,938 males, 78,189 females) classified by age: infant, aged 0–3 years; early childhood, aged 4–8 years; late childhood, aged 9–12 years; adolescent, aged 13–18 years; adult, aged 19–64 years; elderly, aged above 65 years. Multiple logistic regression analysis was performed, and the odds ratio (OR) of various mental illnesses – attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder (ASD), conduct disorder, depression, anxiety, suicidal ideation, schizophrenia, and sleep disorder – were calculated for patients with and without AD.Results: The incidence of depression was not significantly different between AD and non-AD patients. Severe AD showed a high OR of depression (moderate AD OR=1.75; severe AD OR=3.15, P
