ATLANTA The number of young people who had a food or digestive allergy increased 18 percent between 1997 and 2007, according to a new report issued Wednesday by the Centers for Disease Control and Prevention.
In 2007, approximately 3 million U.S. children and teenagers under age 18—or nearly 4 percent of that age group—were reported to have a food or digestive allergy in the previous 12 months, compared to just over 2.3 million (3.3 percent) in 1997.
The report found that eight types of food account for 90 percent of all food allergies: milk, eggs, peanuts, tree nuts, fish, shellfish, soy and wheat. Reactions to these foods by an allergic person can range from a tingling sensation around the mouth and lips, to hives and even death, depending on the severity of the reaction.
Children with food allergy are two to four times more likely to have other related conditions such as asthma and other allergies, compared to children without food allergies, the report said.
The mechanisms by which a person develops an allergy to specific foods are largely unknown. Food allergy is more prevalent in children than adults. Most affected children will outgrow food allergies, although food allergy can be a lifelong concern.
The findings are published in a new data brief, “Food Allergy Among U.S. Children: Trends in Prevalence and Hospitalizations.” The data are from the National Health Interview Survey and the National Hospital Discharge Survey, both conducted by CDC?s National Center for Health Statistics.
