Abstract:This study examined the associations between duration of breastfeeding and childhood cognitive abilities and academic achievement between age 8 to 18, using data collected during the course of an 18-year longitudinal study of a birth cohort of more than 1000 children. Increasing duration of breastfeeding was associated with consistent and statistically significant increases in: (i) intelligence / IQ at ages 8 and 9 (ii) reading comprehension, mathematical ability and scholastic ability assessed during the period from 10 to 13 years (iii) teacher ratings of reading and mathematics assessed at 8 and 12 years (iv) higher levels of attainment in school leaving examinations. The findings persisted after taking into account the age of the mother and her socio-economic status.

Discussion:The children included in this study were born at a time when human milk was already contaminated by industrial synthetic chemicals such as PCBs and dioxins. However the advantages of breastfeeding obviously outweighed the disadvantages. See entries 0129 and 0130
