Egg allergy rates declining in Australia

Australian children have seen a 17% reduction in egg allergies following the implementation of 2016 guidelines recommending egg introduction in the first year of life. A study by the University of Queensland and the Murdoch Children’s Research Institute involving over 7,200 children found the biggest benefits among infants with eczema.

The research, published in JAMA Pediatrics, assessed whether allergy rates declined after the 2016 feeding guidelines took effect. Australia currently reports one of the highest food allergy rates in the world, with one in 10 infants affected.

Associate Professor Jennifer Koplin of the University of Queensland stated this is the first study to demonstrate a reduction in egg allergy at a population level following new feeding guidelines.

Why did egg allergy rates drop in Australian children?

The decline is attributed to the shift toward introducing eggs during the first year of life. Two population-based studies involving more than 7,200 children provided the data for these findings.

Infants with eczema, a known risk factor for food allergies, experienced the most significant impact. According to Associate Professor Rachel Peters of the Murdoch Children’s Research Institute, egg allergy rates among these babies dropped from 35% to 22%.

How do current allergen guidelines differ from previous advice?

Current guidelines represent a major departure from the advice given in the 1990s and early 2000s. Dr. Peters noted that previous recommendations suggested parents delay introducing eggs and other allergenic foods until children were 1 to 3 years old if a strong family history of allergy existed.

Brisbane child health nurse Sarah McKenzie reports that parents frequently ask when to start eggs in her clinic. The updated research provides nurses with clearer evidence to guide these conversations.

Expert Insight: Samantha Carter notes that the transition from avoidance to early introduction reflects a fundamental shift in pediatric allergy management. By challenging the immune system early, these guidelines aim to prevent the very allergies that previous decades of “delay and avoid” strategies may have inadvertently encouraged.

What are the current recommendations for introducing allergens?

The Australasian Society of Clinical Immunology and Allergy (ASCIA) recommends introducing eggs soon after a baby starts solids, which usually occurs around six months.

ASCIA guidance also states that other common allergens should be introduced before a child reaches 12 months. These include tree nuts, wheat, sesame, fish, and cow’s milk.

What happens next for allergy prevention?

Egg allergies remain common despite the downward trend. Dr. Koplin noted that some babies may still develop allergies even when parents follow the guidelines.

Further research is currently underway to identify additional prevention strategies. These findings may provide continued reassurance to parents to follow current recommendations while researchers seek to further lower allergy rates.
