We were able to follow about 68 % of the participants, which is a very good follow-up rate, we observed that breastfeeding was positively associated with performance and intelligence at 30 years old, as well as with education, school achievement and higher monthly incomes.

It's suggesting that the positive effect of breastfeeding on IQ leads to a higher income, this is our main finding at this moment.
