AIM: This study was aimed at systematically reviewing evidence of the association between breastfeeding and performance in intelligence tests.
METHODS: Two independent searches were carried out using Medline, LILACS, SCIELO and Web of Science. Studies restricted to infants and those where estimates were not adjusted for stimulation or interaction at home were excluded. Fixed- and random-effects models were used to pool the effect estimates, and a random-effects regression was used to assess potential sources of heterogeneity.
RESULTS: We included 17 studies with 18 estimates of the relationship between breastfeeding and performance in intelligence tests.
