Breast is best for children's IQ

Breastfeeding for longer can boost children's IQ and language ability, new research has suggested.

Seven-year-olds who were breastfed until their first birthday were likely to score four points higher on a verbal IQ test than those who had been bottle-fed as babies, according to a US study published in JAMA Pediatrics.
       
Scientists uncovered a clear link between the duration of breastfeeding and intelligence test performance at age seven.

Verbal intelligence scores increased by 0.35 points for every extra month of breastfeeding, while non-verbal IQ scores rose by 0.29 points for every additional month a child was breastfed.

The improvement was most noticeable among children who were exclusively breastfed, who boosted their verbal IQ scores by nearly a point per month.

Seven-year-olds who were exclusively breastfed for the first six months after birth had an almost five point advantage over those who were bottle-fed.

The scientists, led by Dr Mandy Belfort of Boston Children's Hospital, wrote: "Our results support a causal relationship of breasfeeding in infancy with receptive language at age three and with verbal and non-verbal IQ at school age.

"These findings support national and international recommendations to promote exclusive breastfeeding through age six months and continuation of breastfeeding through at least age one year."
