Food allergy may be underdiagnosed in children on Medicaid

Prevalence of food allergy among Medicaid-enrolled children across the U.S. was substantially lower (0.6 percent), compared to previous national estimates using parent surveys (7.6 percent) and reports of physician confirmation of food allergy (4.7 percent). The study, published in Academic Pediatrics, was the first to analyze Medicaid claims data of over 23 million children to estimate prevalence of food allergy diagnosis.
