- 31.6 million Americans are estimated to have symptoms of eczema, including 17.8 million with symptoms of atopic dermatitis.
- Worldwide, about 20 percent of children and up to 3 percent of the adult population have some form of eczema. Those who live in developed countries or colder climates seem to be more prone to developing eczema.
- Hand dermatitis accounts for 20–35% of all U.S. eczema cases, affecting up to 10% of the U.S. population.
- In a 2007 U.S. survey, just over one‐third (37.1%) of those with eczema symptoms reported a physician diagnosis.
General aspects of eczema
- There are at least 11 unrelated skin diseases that produce eczemas.
- Studies have found that 1/3 to nearly 2/3 of children and young people with atopic eczema also had a food allergy.
- Statistics in the United States show that about 80% of contact dermatitis is irritant‐based and about 20% is allergic.
Age of onset
- Seventy percent of eczema cases start in children younger than 5 years old, and about 60% of infants who have eczema continue to have one or more symptoms in adulthood.
- Atopic dermatitis affects between 8.7%–18.1% of all infants and young children.
- In a 2007 study of 21 patients with mild to moderate atopic dermatitis, applying an oatmeal‐based cream twice daily to eczema patches was found to “significantly improve symptoms after the first and second weeks of treatment.”*
