The study did show some positive short - term
cognitive effects of breastfeeding, but no long - term advantages.

We confirmed this gene — environment interaction in two birth cohorts, and we ruled out alternative explanations
of the finding involving gene — exposure correlation, intrauterine growth, social class, and maternal
cognitive ability, as well as maternal genotype
effects on
breastfeeding and breast milk.
Another strength is that our results provide a more complete assessment
of socioeconomic inequalities in
breastfeeding rates, by estimating both relative and absolute inequalities, than common practice in inequality assessments.23 Finally, our study analysed
effects of the intervention not only on an immediate, direct outcome (
breastfeeding) but also on a long - term consequence
of breastfeeding (child
cognitive ability) that is associated with important health and behavioural outcomes in later life.27
Research in the United States, Canada, Europe, and other developed countries, among predominantly middle - class populations, provides strong evidence that human milk feeding decreases the incidence and / or severity
of diarrhea,1 - 5 lower respiratory infection,6 - 9 otitis media,3,10 - 14bacteremia, 15,16 bacterial meningitis, 15,17 botulism, 18 urinary tract infection, 19 and necrotizing enterocolitis.20, 21 There are a number
of studies that show a possible protective
effect of human milk feeding against sudden infant death syndrome,22 - 24insulin - dependent diabetes mellitus,25 - 27 Crohn's disease, 28,29 ulcerative colitis, 29 lymphoma, 30,31 allergic diseases,32 - 34 and other chronic digestive diseases.35 - 37
Breastfeeding has also been related to possible enhancement
of cognitive development.38, 39
The long - term
effects of sexual abuse are divided into seven domains that may impact
breastfeeding behavior: post-traumatic stress disorder,
cognitive distortions, emotional distress, impaired sense
of self, avoidance, interpersonal difficulties, and health problems.
The most recent evidence for an
effect of infant feeding on
cognitive development will be reviewed, but it will go beyond IQ, beyond just a number, and will look at the normal brain development that happens when infants are
breastfed and what developmental, educational and social consequences occur when infants are artificially fed.
Table 3 summarizes the
effect of covariate adjustment on estimated relationships between
breastfeeding duration and child
cognitive outcomes.
To examine whether the
effects of breastfeeding varied for boys and girls, the analyses were extended to include tests
of interactions between gender and measures
of breastfeeding in their
effects on
cognitive and educational outcomes.
Another possibility is that the benefits
of breastfeeding depend on the precise content
of breast milk — that only milk with higher levels
of DHA fatty acid (docosahexaenoic acid) confers special
effects on
cognitive ability (Bernard et al 2017).
The most recent follow - up study reported associations between duration
of breastfeeding and childhood
cognitive ability and academic achievement extending from 8 to 18 years in a New Zealand cohort
of 1000 children.19 This study found that these
effects were significant after controlling for measures
of social and family history, including maternal age, education, SES, marital status, smoking during pregnancy, family living conditions, and family income, and measures
of perinatal factors, including gender, birth weight, child's estimated gestational age, and birth order in the family.
