SATURDAY, Feb. 23 (HealthDay News) -- Race and possibly genetics
play a role in childhood allergies, according to a new study.
Researchers at the Henry Ford Hospital in Detroit skin-tested
more than 500 children, all of whom were 2 years old, for three
food allergens -- egg whites, peanuts and milk -- and seven
The tests showed that about 20 percent of black children and 6.5
percent of white children were sensitized to a food allergen, while
nearly 14 percent of black children and 11 percent of white
children were sensitized to an environmental allergen.
Black children with an allergic parent were sensitized to an
environmental allergen about two and a half times more often than
black children without an allergic parent, according to the study,
scheduled for Saturday presentation at the annual meeting of the
American Academy of Allergy, Asthma and Immunology, in San Antonio,
Sensitization means that a person's immune system produces a
specific antibody to an allergy -- not that a person will
experience allergy symptoms, the researchers pointed out.
"Our findings suggest that African-Americans may have a gene making them more susceptible to food allergen sensitization or the sensitization is just more prevalent in African-American children than white children at age 2," allergist and study lead author Dr. Haejim Kim said in a Henry Ford Health System news release.
"More research is needed to further look at the development of allergy," Kim added.
Studies presented at medical meetings should be viewed as
preliminary until published in a peer-reviewed journal.
