And among these allergic children, 38.7% had a history of severe reactions and 30.4% were allergic to more than one type of food, they reported online in Pediatrics.
Previous studies have suggested that the prevalence of food allergy among U.S. children ranged from 1% to 8%, with an analysis of data from the 2005 National Health and Nutrition Examination Survey finding a prevalence of 4.2% in children ages 1- to 5-years-old.
These earlier estimates were imprecise, and also provided no information on the severity of the allergies, so Gupta’s group conducted a cross-sectional survey using a representative sample of households with children.
