Food allergy assessment
Parents were advised to introduce common food allergens including egg,
dairy and peanut early during weaning, as per national guidelines.
Suspected cases of food allergy were clinically assessed by the blinded
investigator and skin prick testing (SPT) was performed, as indicated.
Infants also had SPT to egg, dairy and peanut if they hadn’t safely
consumed these foods by 12 months. Where deemed necessary by the allergy
team, those with a positive SPT or a reaction suggestive of food allergy
were invited for an oral food challenge (OFC).
