dc.description.abstract Aim: Breastfeeding is associated with IQ, school attendance and income. Despite the known benefits of breastfeeding, the rate of exclusive breastfeeding up to 6-months is low globally. We examined the effect of short-term breastfeeding on long-term IQ. Methods: In this secondary analysis of the prospective Cork BASELINE Birth Cohort Study, children were categorised as predominantly breastfed (n = 288) versus exclusively formula-fed (n = 254) at 2-months of age. Infants (n = 404) receiving mixed-feeding were excluded. Outcome was assessed using the KBIT II at 5-years. Multivariable linear regression was used to adjust for confounding variables. Results: Following adjustment for confounding variables, children, predominately breastfed at 2-months of age, demonstrated increased overall IQ (2.00 points (95% CI: 0.35 to 3.65) ; p = 0.018) and non-verbal IQ at 5-years of age (1.88 points (95% CI: 0.22 to 3.54); p = 0.027) compared to those never breastfed. No significant relationship was found with verbal IQ (p = 0.154). Conclusion: A significant increase in composite and non-verbal IQ at 5-years of age was associated with short-term breastfeeding. This study adds to a growing body of evidence that short-term breastfeeding promotes healthy cognitive development. en
