Urban kids more likely to have food allergies than rural ones

Children living in more populated urban have a much higher prevalence of food allergies than those living in rural areas, according to a new study. This is the first study to track children’s food allergies by geographical location in the United States. In particular, kids in large cities are more than twice as likely to have peanut and shellfish allergies compared to kids living in rural areas.

The study included 38,465 children, 18 years and under, who comprised a representative sample of U.S. households. Their food allergies were mapped by ZIP code. Here are the key findings of the study:

In urban centers, 9.8 percent of children have food allergies, compared to 6.2 percent in rural communities.

Peanut allergies are twice as prevalent in urban centers as in rural communities, with 2.8 percent of children having the allergy in urban centers compared to 1.3 percent in rural communities. Shellfish allergies are more than double the prevalence in urban versus rural areas; 2.4 percent of children have shellfish allergies in urban centers compared to 0.8 percent in rural communities.
Food allergies are equally severe regardless of where a child lives, the study found. Nearly 40 percent of food-allergic children in the study had already experienced a severe, life-threatening reaction to food.

The states with the highest overall prevalence of food allergies are Nevada, Florida, Georgia, Alaska, New Jersey, Delaware, Maryland and the District of Columbia.
