Hay fever or respiratory allergy starts to be present in the early childhood and is related to immunoglobulin E (IgE)- mediated reactions to various allergens in the nasal mucosa. The purpose of this study is, in children up to 6 years, to investigate various infant feeding patterns in the first 6 months of life as risk factors of hay fever or respiratory allergy compared to direct breastfeeding for at least 3 months. The Infant Feeding Practice Study II was conducted between 2005 and 2007 and its 6- year follow up was done in the year 2012, provided data on feeding modes in infancy and, based on parental reports, doctor diagnosed hay fever in the first six year of life (n=1,387). Log-linear models were used to estimate the prevalence ratios (PRs) of hay fever in the first 6 years of life for different infant feeding patterns adjusting for confounders. Compared to direct breastfeeding for at least 3 months (BF3m), the combination of direct breastfeeding (BF), pumping and feeding (P&F) of stored breast milk, and formula feeding (FF) since birth (BF/P&F/FF) showed a statistical significant higher risk of hay fever/respiratory allergy in the first 6 years of life (PR=1.81 CI: 1.11, 2.91). In addition, formula feeding for the first 2-3 months followed by a combination of formula and solid food (FF2-3) was also related to a higher risk of hay fever (PR=1.66 CI: 1.01, 2.64). Among the confounders, both maternal and paternal history of hay fever was associated with hay fever/respiratory allergy.
