【社会人文】智力与母乳喂养相关
By Tariq Panja
LONDON (AP) ─ Breast-fed children are more intelligent than their bottle-fed counterparts, but this has nothing to do with the content of the milk they receive, a study published in the British Medical Journal said.
For decades scientists have been looking for a correlation between feeding and intelligence, but the report says genetic and environmental factors affect a child's intellect.
Researchers, who analyzed data from more than 5,000 children and 3,000 mothers in the United States, found that mothers who breast-feed tend to be more intelligent, according to a study published Wednesday on the journal's Web site.
“When this fact was taken into account, most of the relationship between breast-feeding and the child's intelligence disappeared,'' said Jeff Dar, one of the report's authors.
“This research shows that intelligence is determined by factors other than breast-feeding,''
The report won't end the debate about the relationship between intelligence and breast-feeding.
“The problem is trying to show the impact of breast-feeding over and above outside variables,'' said Mike Woolridge, senior lecturer in infant feeding at the University of Leeds.
He said other studies on the subject have claimed a link to intelligence.
“I fundamentally believe breast-feeding builds a better, more balanced brain in terms of its chemical composition and I'm sure you can measure that in terms of brain performance,'' Woolridge said.
The researchers found that children who were breast-fed did better on IQ tests, but this was because their mothers were more intelligent, better educated and able to provide a more stimulating home environment.
Part of the research methodology included testing pairs of siblings, for whom feeding habits differed.
“Comparing two people from the same family like this is a good way of getting results that are less affected by family background. This confirmed the earlier results ─ the breast-fed child was no more intelligent,'' Dar said.
Dr. Chris Lucas, director of the Early Childhood Service at the New York University Child Study Center, praised the report for taking into account the impact of maternal intelligence on the findings.
“Intelligence is probably one of the most heritable things. Intelligence of a child is very much determined by the intelligence of the parents,'' he said. “If you don't measure the mother's intelligence, it may appear that there is a link with breast-feeding.''
Dar said though his team's study found no link to intelligence, breast-feeding was “definitely the smart thing to do,'' because of other benefits to both mother and child, including a stronger ability to ward off infections, respiratory illnesses and protection against developing allergies. 认领了...

智力与母乳喂养的关联

LONDON (AP) ─ Breast-fed children are more intelligent than their bottle-fed counterparts,

英国医学杂志公布的一项研究表明：母乳喂养儿童比人工喂养的对照组儿童聪明，但这并非由于他们吸收的乳品所含成分差别引起。
For decades scientists have been looking for a correlation between feeding and intelligence,
but the report says genetic and environmental factors affect a child's intellect.
数十年来，科学家们总在寻找着喂养与智力之间的关联。但是这项报道认为基因与环境因素（决定性？）影响着孩子的智能。
Researchers, who analyzed data from more than 5,000 children and 3,000 mothers in the United States, found that
mothers who breast-feed tend to be more intelligent, according to a study published Wednesday on the journal's Web site.
根据该杂志网站周三公布的调查，研究者们分析了美国5000多名儿童及3000多名母亲的资料数据后，发现选择母乳喂养的母亲往往具有更高的智力。
“When this fact was taken into account, most of the relationship between breast-feeding and the child's intelligence
disappeared,'' said Jeff Dar, one of the report's authors.
“考虑到事实情况，母乳喂养与孩子智力之间的关联大部分都不存在了”这篇报道的作者之一杰夫·戴（Jeff Dar）这样说道。
“This research shows that intelligence is determined by factors other than breast-feeding,''
“这项研究说明智力是由除母乳喂养之外的其他因素决定的。”
The report won't end the debate about the relationship between intelligence and breast-feeding.
然而，这篇报道并没有了结智力与母乳喂养间关联的争论。
