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 severe, potentially life-threatening, food-induced reactions. This suggests a north-to-south increase in prevalence rates, which is at odds with studies supporting the role of vitamin D deficiency in the mechanism of developing food allergy.
