"For patients with an established diagnosis of food allergy, 35 percent went on to develop asthma," said study senior author Dr. Jonathan Spergel. He is chief of the division of allergy and immunology at the Children's Hospital of Philadelphia.
"Patients with multiple food allergies were at increased risk of developing asthma as compared to those with a single food allergy," he added in a hospital news release.
Those rates are about double that of children and teens in the general population, the study authors said. However, this study doesn't prove a cause-and-effect link between these factors.
The study's lead researcher was Dr. David Hill. "Of the major food allergens, allergy to peanut, milk and egg significantly predisposed children to asthma and allergic rhinitis," Hill said.
"Eczema, asthma and allergic rhinitis are among the most common childhood medical conditions in the U.S.," he noted.
Hill, who is an allergy and immunology fellow, added that there's a greater need for more information on these conditions because the rates have been changing.
The study was published recently in the journal BMC Pediatrics.
