Atopic dermatitis (AD) may be especially active and severe among older adults, and it may be associated with increased risk of comorbid conditions common in later stages of life, including osteoporosis, dementia, and cardiovascular disease.

During the Revolutionizing Atopic Dermatitis virtual symposium, Katrina Abuabara, MD, highlighted the epidemiology and burden of AD among older adults. She began by noting that the disease peaks in infancy and older adulthood. In an analysis that she and her colleagues made of physician-diagnosed AD among more than 8.6 million patients in the United Kingdom between 1994 and 2013, the mean prevalence in a given year was 12.3% among those aged 0-17 years, 5.1% among those age 18-74 years, and 8.7% among those age 75 and older.
"We saw what we expected in early infancy with very high rates of active disease," said Abuabara, associate professor of dermatology and epidemiology at the University of California, San Francisco. "We also saw a second peak in older adulthood. This was more surprising to us because the disease hadn't been as well studied in this population." Researchers who analyzed datafrom the Global Burden of Disease Study, which evaluates disease-related morbidity and mortality worldwide, found a somewhat attenuated peak but a similar trend around the world.
