AIM: To investigate the relationship between factors which influence external microbial exposures (FEMEs), previously identified to be protective or to increase the risk of the development of allergic disease, and cognition and behaviour in infants 2 years of age in an Australian population. METHOD: The Barwon Infant Study is a birth cohort (n = 1074) in Victoria, Australia. Comprehensive questionnaire, clinical and biological measures were collected at multiple time oints. Multiple linear regression was used to evaluate the associations between 56 FEMEs and 3 outcomes; cognition (Bayley Scales of Infant and Toddler Development (BAYLEY-III)) (n = 667, mean (standard deviation) age = 2.45 (0...View full abstract
