Who is affected by atopic dermatitis

atopic dermatitis is a common skin condition that affects 10% to 20% of children in industrialized countries and urban Africa. It can occur in adults but occurs mostly in young children.

• Of children with atopic dermatitis, approximately 50% first develop symptoms in their first year of life and 30% between ages 1 and 5.
• Although older studies have indicated that most children outgrow the condition, more recent studies report that many people continue to have relapses or to have the condition, although not as severely, as teenagers and adults.

People with a history of atopic dermatitis often have other allergic conditions. Of affected children:

• About 80% develop allergic rhinitis or asthma later in childhood.
• Up to 40% of children with moderate to severe atopic dermatitis also have some type of food allergy.

atopic dermatitis affects people of all races.

The prevalence of atopic dermatitis has been increasing over the last few decades, possibly due to environmental and lifestyle changes.
