The prevalence of suicidal ideation in patients with mild, moderate, and severe atopic dermatitis between the age of 15 to 49 years were 0.21%, 6%, and 19.6%, respectively. In addition, the prevalence of homicide-suicidal ideation in mothers or fathers of patients (aged 0-14 years) with mild, moderate, and severe atopic dermatitis were 0.11%, 0.35%, and 3.28%, respectively. These results indicate that patients with atopic dermatitis or even parents of patients with atopic dermatitis have high prevalence of suicidal ideation.
