The number of US children with food allergies has grown by 18% in the past decade, according to a report by the national Centers for Disease Control and Prevention (CDC).
About 3 million US children and adolescents—nearly 4% of this age group—were reported to have a food or digestive allergy in 2007 compared with 2.3 million (3.3%) in 1997, according to data from the National Health Interview Survey, a national survey of the parents of 9500 children. These data, as well as data from the National Hospital Discharge Survey, were included in a report published by the CDC in October (http://www.cdc.gov/nchs/data/databriefs/db10.htm#Data).
