Overview
- Published in Pediatrics, the Children’s Hospital of Philadelphia study examined electronic records for roughly 120,000–125,000 children under age 3 across nearly 50 pediatric practices.
- Peanut allergy diagnoses fell about 43% after the 2017 guidance compared with 2012–2015, contributing to a 36% drop in overall IgE-mediated food allergies in this age group.
- Researchers estimate roughly 57,000–60,000 fewer children developed peanut allergies since early-introduction recommendations began in 2015.
- Egg has now surpassed peanut as the most commonly diagnosed new food allergy in young children during the study period.
- Authors and an accompanying editorial note limits including lack of direct feeding data, a subset of practice sites, and follow-up only to age 3, while uptake of early-introduction advice by clinicians and caregivers remains uneven.
