5 Key Takeaways

• 1

  A population-based study found lower egg allergy prevalence in Australian infants after guidelines recommended earlier egg introduction.

• 2

  The median age for egg introduction decreased from 8 months to 6 months, with the proportion of infants introduced to egg by 6 months rising from 25% to 57%.

• 3

  Egg allergy prevalence was estimated at 9.2% in the earlier cohort and 7.6% in the later cohort, reflecting a relative reduction of approximately 18%.

• 4

  The reduction in egg allergy was more significant among infants with early eczema, decreasing from 34.6% to 21.9%.

• 5

  The findings suggest that food-allergy prevention recommendations can lead to measurable population-level changes when widely adopted.
