Brain cortical features measured from MR imaging such as cortical thickness and surface area were extracted and compared among groups and correlated with Behavior Rating Inventory of Executive Function test scores.RESULTS: Clusters in the frontal and occipital lobes showed significant differences (cluster-wise P  ≤  .05, corrected for multiple comparisons) in cortical thickness or surface area among the 3 diet groups. The effects were more prominent for boys, particularly for comparison of the milk formula fed versus soy formula fed boys. Assessments of executive function and behavior showed significantly lower Behavior Rating Inventory of Executive Function test scores in soy formula fed versus milk formula fed groups, which were mostly attributed to differences in boys. There were no differences between milk formula fed and breastfed groups for either sex. Mean cortical thickness for several of the clusters in the brain showing infant diet–associated effects significantly correlated with Behavior Rating Inventory of Executive Function scores.CONCLUSIONS: Choices of infant diets (ie, breastfed, milk formula fed, soy formula fed) may have long-term and sex-specific effects on the cortical development and executive function and behavior of children’s brains.BFbreastfedBRIEFBehavior Rating Inventory of Executive FunctionMFmilk formula fedSFsoy formula fed
