Egg and peanut intake in one year old children enrolled in the babyeats study

Methods: We investigated 1-year-old (n = 1108) and 6-year-old (n = 675) children in the grass pollen season from the HealthNuts cohort. Grass pollen concentrations were measured using a volumetric spore trap and considered on the day of testing (lag 0), up to three days before (lag 1-lag 3) and cumulatively (lag 0–3). Associations between grass pollen and specific food sensitisation (skin-prick test 2 mm at age 1 year and 3 mm at age 6 years), presence of eczema, challenge-confirmed food allergy, reaction threshold to oral food challenges (OFC) and serum food-specific IgE levels were analysed using either general additive logistic or quantile regression models. Interactions were investigated using likelihood ratio tests.
