Abstract
The prevalence of food allergies in New Zealand infants is uncertain but is believed to be similar to Australia, exceeding 10%. Current recommendations for reducing food allergy risk are to offer all major food allergens to infants from as early as six months of age (start of complementary feeding), and before 12 months of age. However, little is known regarding parental practices around introducing major food allergens. This study aimed to explore parental offering of major food allergens to infants during complementary feeding, and parent-reported food allergies. The cross-sectional study is a secondary analysis of the multi-centre (Auckland and Dunedin) First Foods New Zealand study of 625 parent-infant dyads. Participants were recruited in 2020-2022 when infants were 7-10 months of age. Questionnaires assessed sociodemographic characteristics, complementary feeding approach, infant pouch use and parental responses to five food allergy questions. All major food allergens had been offered to only 17% of infants by 9-10 months of age. Having offered egg, peanut, tree nuts, sesame, soy and seafood was more commonly associated with using a baby-led complementary feeding approach than a parent-led approach (p < 0.001). Frequent baby food pouch use was associated with a lower likelihood of offering egg and peanut (both p < 0.001). Overall, 12.6% of infants had a reported food allergy, with symptomatic response after exposure being the most common diagnostic tool. Most infants are not offered all major food allergens during early complementary feeding, with some parents actively avoiding major food allergens in the first year of life. These results provide up-to-date knowledge of parental practices, highlighting the need for more targeted advice and strategies to improve parental engagement with allergy prevention and diagnosis.
