A UK study finds that children who are breastfeeding in six months show measurable profits in IQ, Reading and Math skills, with unique benefits for language and conversation.

In a recent article in the magazine NutrientsResearchers at the University of Bristol in the United Kingdom examined the correlations between breastfeeding at the age of six months and a wide range of neurogenic effects to delayed adolescence.
Their findings indicate that, despite demographic and social influences, more than 40 results, including better academic skills, higher ratings of quoter information (IQ) and improved speech skills may be related to breastfeeding.
Background
Previous studies have explored the impact of breastfeeding on children’s cognitive and behavioral development. However, the results were inconsistent. Some studies have shown clear benefits, while others have reported mixed or no results, often due to limited signs or fluctuations in the measurement tools.
One of the strongest evidence comes from a randomized controlled test (RCT) in Belarus, which showed better verbal IQs, vocabulary, writing and reading skills in children whose mothers received breastfeeding support, with improvements remaining in adolescence. However, no behavior differences were observed between intervention and control groups.
Systematic revisions largely support a positive correlation between breastfeeding and IQ, and some extend to executive, knowledge and behavior. However, the results are usually small. Analyzes that compare breastfeeding duration suggest that breastfeeding over 6 months provides additional benefits. Larger observation studies also show wider results.
For example, Scotland’s data for 177,000 children found lower risk of learning difficulties among lactating children, while Japanese and Australian groups reported reduced development delays and enhanced effects of language and intelligence.
However, despite the consistent findings for IQ, there was a limited investigation of other neuro -conspiracy effects based on large data sets.
For the study
The study used data from the timeless study of parents and children Avon (ALSPAC), which hired over 14,500 pregnant women in the United Kingdom. Mothers and associates completed questionnaires during pregnancy and after birth, providing data on infants’ diet and background characteristics.
Breastfeeding was assessed in 4 weeks, 6 months and 15 months. For this analysis, breastfeeding in six months was the main exposure, without being distinguished between exclusive and partial breastfeeding.
Several confusion were included to take into account social and demographic influences, namely parent and father -education, motherhood at birth, birth class, home, manner of delivery and smoking of the mother during pregnancy. These factors are known to affect both breastfeeding practices and children’s results.
The neurogenic results were evaluated through 373 continuous measures collected from infancy through adolescence through parents, teachers and self -reports, as well as immediate tests by ALSPAC staff.
Multifunctional linear reflux was used to adapt to the confusing factors. The missing data was not attributed to the possibility of non -random patterns, with some results showing up to 62% missing (eg IQ at the age of 15). The researchers applied a two -stage statistical exam procedure, requiring an initial non -adjusted P <0.0001 and then a customized threshold p <0.001 for the results that must be considered significant.
Basic findings
Of the 11,337 mothers who responded to six months, 28.7% were still breastfeeding, 24.4% had never breastfed and 46.9% had stopped six months ago. Analyzes focused on children who were breastfed in 6 months compared to those who were never breastfed. Children who stopped breastfeeding six months ago were excluded. Of the 373 neurogenic measures, 42 results showed significant adapted compounds.
Early development tests have shown a few constant differences, with fine motor skills at ages 30 and 42 months being the only preschool features that are strongly associated with breastfeeding. IQ showed consistently positive results, as children were breastfed for six months rated higher in verbal, performance and total IQ at ages 8 and 15, with an average profit of about 4.1 to 5.1 IQ points.
Reading ability also showed strong compounds in multiple measures, including national evaluations, while spelling compounds were weaker. The results of the languages ​​were mixed, but significant improvements were observed in realistic conversation skills at the age of nine, as measured by the children’s communication control list (CCC).
Breastfeeding children had better math performance both in teachers and national evaluations, but similar associations for science did not reach the strict limit of importance (p <0.001).
The benefits of behavior were limited, although breastfeeding children showed reduced hyperactivity and lower levels of activity in preschool years. Additional findings included a greater chance of a right and more inner control over the age of eight.
Conclusions
This study found that breastfeeding for six months was associated with higher IQ, improved reading and mathematics performance, stronger thinner motor skills and better conversation skills, with weaker behaviors and personality associations.
Specifically, realistic speech improvements at the age of nine appeared as a new finding. The results are largely aligned with previous tests and reviews, enhancing the spiritual benefits of breastfeeding.
The advantages include population -based design, objective teacher and testing data and adaptation for multiple confusing factors, including parents’ education. The recording of the power into six months of minimized bias.
However, restrictions include wear and tear, a primarily white European group that limits generality, dependency only on continuous results and the possibility that strict statistical limits (p <0.0001 followed by p <0.001) may have hidden some real correlations.
In conclusion, breastfeeding for six months was steadily associated with long -term cognitive advantages in this group, with no evidence of damage. While the causality cannot be confirmed, the findings support breastfeeding as beneficial for the neurogenic development of children.
