A new study has indicated that at least two-thirds of all adult asthma sufferers also have an allergy.
The research concluded that an astonishing 75 percent of asthmatic adults aged 20- to 40-years-old, and 65 percent of asthmatic adults aged 55 years and older, have at least one allergy.
"Allergists have known the prevalence of allergies among asthmatic children is high at 60 to 80 percent, but it was thought allergies were not as common in asthmatic adults," said allergist Paula Busse, MD, lead study author. "These findings are important, and can help lead to proper diagnosis and treatment."
While asthma is frequently associated with children, it is not uncommon among adults 60 years and older, affecting three to seven percent. This number is likely higher, however, because asthma is often underdiagnosed in older adults, the report said.
The study has been published in the April issue of Annals of Allergy, Asthma and Immunology.
