CHAPEL HILL, N.C.A study published in the May issue of the Journal of Allergy and Clinical Immunology showed that obese children and adolescents are at increased risk of having some kind of allergy, especially to a food. The study (2009 May;123(5):1163-9, 1169.e1-4. Epub 2009 Feb 23) sought to examine the association of obesity with total and allergen-specific Immunoglobulin E (IgE), antibodies that fight allergies, levels and allergy symptoms in 4,111 U.S. children and adolescents aged 2 to 19 by reviewing the National Health and Nutrition Examination Survey data from 2005-2006. IgE levels were 26 percent higher among obese and overweight children than among normal-weight children. The odds for having higher IgE levels were increased in the obese children compared with that seen in those of normal weight. The rate of having a food allergy was 59 percent higher for obese children. The study concluded obesity might be a contributor to the increased prevalence of allergic disease in children, particularly food allergy, but the research does not prove obesity causes allergies.

The study was funded by the National Institute of Environmental Health Sciences (NIEHS) and the National Institute of Allergy and Infectious Diseases (NIAID), both parts of the National Institutes of Health.
