Childhood Food Allergy Epidemiology

The Prevalence, Severity, and Distribution of Childhood Food Allergy in the United States

Prior to this landmark study estimates of food allergy in the US ranged from 2–8%. This study of 40,000+ US households found that 8% or 1 in 13 children had a food allergy.  We also found that roughly 40% of these children had experienced a severe reaction in the past.  CLICK HERE TO READ MORE. 

The 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 more severe reactions.  CLICK HERE TO READ MORE.   

The High Economic Impact of Childhood Food Allergy in the United States

This paper was the first to estimate the economic impact of childhood food allergy in the United States.  After surveying 1643 familes of children with food allergy we estimated the overall cost of food allergy to be $24.8 billion annually, which corresponds to $4184 per child.

The Epidemiology of Pediatric Milk Allergy in the US

Milk is one of the most common food allergies, yet little is known about its distribution and diagnosis. This study  found that 20% of food-allergic children were allergic to milk and that Black and Asian kids were half as likely as their white peers to have a milk allergy.  CLICK HERE TO READ MORE.  

Parent Report of Childhood Shellfish Allergy in the US

Although shellfish allergy frequently results in ER visits, national prevalence studies focusing on shellfish allergy in children are scarce. Of the nearly 40,0000 children in the study, 1.3% had a shellfish allergy.  The average age of first reaction to shellfish was 6 years.  CLICK HERE TO READ MORE.  

Epidemiology of Childhood Peanut Allergy 

The goal of this study was to better characterize peanut allergy prevalence, how it is being diagnosed, and the type of allergic reactions that children with peanut allergy tend to have.  We found that childhood peanut allergy, which represents nearly a quarter of all food allergy, presents more severe reactions and is less likely to be outgrown than other food allergies.
