Lenehan SM, Boylan GB, Livingstone V, et al. - Researchers investigated how short-term breastfeeding influence long-term IQ. They performed secondary analysis of the prospective Cork BASELINE Birth Cohort Study categorizing children as predominantly breastfed (n = 288) vs exclusively formula-fed (n = 254) at 2-months of age. Following adjustment for confounding variables, children, they observed increased overall IQ (2.00 points) and non-verbal IQ at 5-years of age (1.88 points) among those who were predominately breastfed at 2-months of age compared with those never breastfed. This study adds to a growing body of evidence supporting the promotion of healthy cognitive development in relation to short-term breastfeeding.
