Breastfed babies seem more likely to do well at high school and to go on to attend college than infants raised on a bottle, according to a new U.S. study.
Professors Joseph Sabia from the American University and Daniel Rees from the University of Colorado Denver based their research on 126 children from 59 families, comparing siblings who were breastfed as infants to others who were not.
By comparing siblings, the study was able to account for the influence of a variety of difficult-to-measure factors such as maternal intelligence and the quality of the home environment.
The study, published in the Journal of Human Capital, found that an additional month of breastfeeding was associated with an increase in high school grade point averages of 0.019 points and an increase in the probability of college attendance of 0.014.
"The results of our study suggest that the cognitive and health benefits of breastfeeding may lead to important long-run educational benefits for children," Sabia, a professor of public policy who focuses on health economics, said in a statement.
