The purpose of the present study was to examine the effect of breastfeeding on the relationship between executive functioning and math achievement for preschool-aged African American children. Although the effects of breastfeeding have been widely researched, the cognitive effects of breastfeeding on African American children has yet to be extensively researched. Thus, the following research will provide insights in identifying cognitive factors that promote development and reduce the achievement gap for African American children in mathematics. It was hypothesized that executive functioning will have a stronger association with math achievement among children who are breastfed. The sample for the study was part of a larger study conducted on nearly 200 four- and five-year-old African American children. The implications that will be discussed are in relation to the disparity of academic achievement among African American children. This study aims to inform future research about how breastfeeding affects the relationship between executive functioning and math achievement among African American children using statistical modeling to perform a moderated data analysis.
