In four related studies about food allergies,
the researchers found a common theme: “Food-allergic individuals need to
increase the awareness of their food allergy among the people around them,” says
lead researcher Matt Greenhawt, M.D., MBA, who conducted the research while he
was a fellow in the Division of Allergy and Immunology at the U-M Health System
and now is an associate at the Allergy & Asthma Center, LLC in the Atlanta metro
area.
“This would include not only telling them that they are food allergic but also
showing them how to treat them and how to recognize signs of an ongoing
reaction,” Greenhawt notes.
The most common food allergens are peanuts, tree nuts, milk, eggs, fish,
shellfish, soy and wheat. Food allergies can lead to death; a life-threatening
reaction caused by allergies is called anaphylaxis. Food allergy occurs in 6 to
8 percent of children 4 years old or under, and in 3.7 percent of adults,
according to the National Institute of Allergy and Infectious Diseases.
Among college students, researchers found that only 50 percent of the students
who identified themselves as having an allergy to a food said they always
avoided the food.
About two-thirds could verify that somebody close to them on campus was aware
that they were food-allergic. About 60 percent could verify that either a
roommate, house mate or suite mate was aware of his or her food allergy.
The findings that cause the most concern, says Marc S. McMorris, M.D., is that
only 43 percent who identified themselves as food-allergic could verify that
they had in their possession an emergency medication to treat a reaction, and
only about 20 percent had self-injectable epinephrine – the recommended
treatment – available to treat a reaction.
“These students are taking unnecessary risks,” says McMorris, medical director
of Food Allergy Service at the U-M Health System. “There are serious issues that
need to be addressed in terms of educating these young adults that it is of
utmost importance to not only maintain emergency medication but to have it with
you at all times.”
At schools and child-care facilities, researchers found that 43 percent of
food-allergic children have had at least one reaction at school, and nearly
two-thirds of these occurred in children in kindergarten or younger. The finding
suggests that these individuals might be at more risk than older children,
McMorris says.
Only one in five of the schools these children attended had a peanut or tree nut
free policy. Less than half of these facilities had staff that were trained to
recognize an ongoing allergic reaction or were trained to treat a reaction,
though the rate was much higher among schools with full-time nurses on staff.
Like on college campuses, the use of self-injectable epinephrine to treat a
reaction was irregular. While nearly three-quarters of the food-allergic
children had epinephrine available, less than one-third received the treatment.
Among the group that received it, one-third received it at a delay of 15 minutes
or greater, which also poses a risk to the children because treatment should
occur immediately.
“Until all students who display symptoms of a severe reaction are receiving
epinephrine, I would say that there’s a significant gap that needs to be
closed,” Greenhawt says.
