- A population-based study estimates an atopic dermatitis (AD) prevalence of 7.3%, and patients tend to have worse QoL and increased risk of anxiety or depression.
Why this matters
- Based on these prevalence estimates, 16.5 million adults would have a diagnosis of AD, with 6.6 million meeting criteria for moderate-to-severe disease.
- Overall AD prevalence was 7.3%.
- 60.1% of cases were classified as mild, 28.9% as moderate, and 11.0% as severe.
- Marital status and level of education were associated with severity in adjusted analysis.
- Patients with AD had higher mean scores in the dermatology life quality index (4.71 vs 0.97; OR, 8.33; P<.001 in adjusted model>
- Patients with AD had higher odds of clinical anxiety and depression (Hospital Anxiety and Depression scale; OR, 3.29 [P<.001 and respectively in adjusted analysis>
- 1278 adults completed a Gfk web survey concerning AD prevalence, severity, and effects on QoL.
- Funding: Asthma and Allergy Foundation of America in partnership with the National Eczema Association sponsored by Sanofi Genzyme and Regeneron.
- Potential misclassification or recall bias.
