Overview
- The Pediatrics study reviewed records for roughly 120,000 to 125,000 children across nearly 50 pediatric practices, using diagnosis codes and epinephrine prescriptions to track trends.
- Peanut diagnoses fell 27% after the 2015 recommendations for high‑risk infants and 43% after the 2017 addendum expanded early introduction, with overall food allergy diagnoses down about 36% to 38%.
- Researchers estimated that early introduction could prevent about one peanut allergy per 300 infants, translating to roughly tens of thousands fewer diagnoses nationally if widely adopted.
- Egg became the most commonly diagnosed allergy in this age group and did not decline significantly, while atopic dermatitis diagnoses increased over the same periods.
- The analysis is observational, did not measure infant diets, and follows children only to age 3, and international data from Australia show smaller declines of about 16%.
