A Spanish study shows that four- and five-year-olds who were breastfed as infants show better cognitive abilities compared to their non-breastfed peers. These children have higher IQs and stronger non-verbal skills.
In the study, Susana Vargas-Pérez, a researcher at the University Rovira i Virgili in Tarragona, analyzed data from two previous studies, ECLIPSES and EPINED. These studies followed 613 children, born in 2013 and 2014, from birth up to 4-5 years of age and collected information on both breastfeeding habits and the children’s cognitive abilities at the age of four.
The results, published in the International Journal of Early Childhood, showed that children who were breastfed between one and eight months performed slightly better in cognitive tests than children who were not breastfed. These children showed higher overall IQ, improved working memory and stronger non-verbal skills.
Children breastfed for more than eight months showed improvements in non-verbal thinking and processing speed, but did not always perform better than those breastfed for one to eight months. This suggests that the greatest cognitive benefits can be achieved in the first eight months, although longer breastfeeding also provides some benefits.
“Our study emphasizes the numerous advantages of breastfeeding and underscores the importance of infants being breastfed through healthcare and health policies. Advocating breastfeeding for the first six months of life is crucial for enhancing lifelong well-being and cognitive development in children“, the study authors write.
The study included both exclusive breastfeeding and mixed feeding (combination of breastfeeding and bottle feeding), which makes it difficult to determine whether exclusive breastfeeding provides greater cognitive benefits. Another limitation is that the study only included children from one region of Spain, which may affect how the results can be applied to other populations.
