Prevalence and Severity of Childhood FA
Prior to our study estimates of food allergy in the US ranged from 2–8%. These studies, however, are limited by small sample size, lack data on method of diagnosis/reaction history, are not specific to children, or are limited to a specific allergen. We set out to find the real prevalence and severity of childhood food allergy in the US. The research team randomly surveyed 40,104 households with children in the US (June 2009 to February 2010). Food allergy prevalence was 8%. READ MORE...
Geographic Variability of Childhood Food Allergy
Using data from our nation-wide prevalence survey, we found that food allergy prevalence was not
associated with latitude or geographic region. Instead, urban residence was associated with increased odds of food allergy and odds of having a history of severe, potentially life-threatening, food-induced reactions. READ MORE...
Physician-diagnosis of Childhood Food Allergy
Using data from the nation-wide prevalence survey, we found that 30% of children with food allergy never receive a formal physician diagnosis; food allergy is under-diagnosed. Lower income and minority households were more likely to have a child with an undiagnosed food allergy. READ MORE...
Food Allergy Research Overview
My work in childhood food allergy is wide-ranging, though I have received the most attention for my epidemiological work in food allergy prevalence, severity, causes and tolerance overall and by specific food allergens. However, I have also published on food allergy knowledge among, parents, the general public and physicians. For physicians, we are working to improve diagnosis and management through clinical support tools. We are also working to determine the economic impact of food allergy.
