Atopic Dermatitis in America Study: a cross-sectional study examining the prevalence and disease burden of atopic dermatitis in the US adult population

Population-based estimates on the prevalence of atopic dermatitis in adults vary widely. The objectives of the present study were to determine the prevalence of atopic dermatitis in the population of the United States, distribution of disease severity, and assess its impact on health-related quality of life. Among 1,278 participating adults, the prevalence (95%CI) of atopic dermatitis was 7.3% (5.9-8.8). 60.1% (56.1-64.1%) of participants were classified as mild 28.9% (25.3-32.7%) as moderate and 11% as severe (8.6-13.7%).
