Today’s Health Tip ~ Does Breastfeeding Boost IQ?

Children Who are Breastfed Have Higher IQ’s and Higher Earning Ability

The researchers found that information about IQ and breastfeeding was available for 3,493 of the 5,914 neonates enrolled. The durations of total breastfeeding and predominant breastfeeding correlated positively with IQ, educational attainment, and income in crude and adjusted analyses. Dose-response associations were identified for breastfeeding duration with IQ and educational attainment. Participants who were breastfed for 12 months or more had higher IQ scores, more years of education, and higher monthly incomes than those breastfed for less than one month, in confounder-adjusted analysis. Based on mediation analysis, IQ was found to be responsible for 72 percent of the effect on income.

“Our results suggest that breastfeeding not only improves intelligence up to adulthood, but also has an effect at both the individual and societal level, by increasing educational attainment and earning ability,” the authors write.
