Adherence to Australian Infant Food Allergen Introduction Guidelines: Factors Influencing Infant Feeding Practices

Area of Science:

• Pediatric Allergy and Immunology
• Public Health Nutrition
• Evidence-Based Guideline Implementation

Background:

• Updated 2016 Australian infant feeding guidelines promoted earlier allergen introduction.
• Understanding community uptake factors is crucial for effective allergy prevention strategies.

Purpose of the Study:

• To investigate how families receive infant feeding advice.
• To identify factors associated with the accuracy and receipt of this advice.
• To determine the impact of feeding advice on allergen introduction timing.

Main Methods:

• A population-based study (EarlyNuts) surveyed 1699 infants aged 11-15 months.
• Parent-completed questionnaires collected data on demographics, feeding advice, and allergen introduction.
• Statistical analysis examined associations between advice receipt, accuracy, and introduction timing.

Main Results:

• 99% of families received feeding advice, with high accuracy for solids, egg, and peanut.
• Accurate advice was strongly linked to timely introduction of peanut, egg, tree nuts, and dairy.
• Maternal child health nurses (MCHNs) were the primary advice source, associated with increased timely introduction of key allergens.
• Infants of parents born outside Australia and families in specific regions received less accurate advice.

Conclusions:

• Widespread receipt and accuracy of infant feeding advice correlate with timely allergen introduction.
• Culturally and linguistically diverse families face lower rates of accurate advice.
• Local council and MCHN programs appear beneficial for guideline dissemination and adherence.
