Background: Atopic dermatitis (AD) is associated with eczematous lesions, pruritus, pain, and sleep disturbance, which may negatively impact mental health over time.
Objective: To determine the predictors and longitudinal course of depressive symptoms in adults with AD.
Methods: A prospective, dermatology practice-based study was performed (N = 695). AD signs, symptoms, and severity and patient health questionnaire-9 (PHQ-9) were assessed.
Results: At baseline, of the 695 participants, 454 (65.32%) had minimal, 139 (20.00%) had mild, 57 (8.20%) had moderate, 27 (3.88%) had moderately severe, and 8 (2.59%) had severe depression. Most had fluctuating levels of depressive symptoms. Feeling bad, thoughts of self-harm, difficulty concentrating, and slow movement were most persistent. Predictors of persistent depression included older age, non-White race, male sex, public or no insurance, more severe itch, skin pain, facial erythema, nipple eczema, sleep disturbance, and presence of pityriasis alba.
Limitations: Single center study.
Conclusion: Depressive symptoms are closely related to and fluctuate with AD severity over time. Improved control of AD signs and symptoms, particularly itch, may secondarily improve mental health.
