Global Burden of Atopic Dermatitis: Examining Disease Prevalence Across Pediatric and Adult Populations World-Wide.

Atopic Dermatitis (AD) is a common, pruritic inflammatory skin disease associated with marked disease burden and substantial health care costs. AD does not discriminate between populations; prevalence estimates vary widely with most studies focusing on general or pediatric populations and a limited number of studies in adult populations solely. The costs of treating AD are staggering. Studies that examine differences in prevalence may be difficult to compare due to differences in study designs. However, understanding the prevalence of AD across populations is critical if we are to improve the lives of patients and caregivers living with this disease.
