新生儿的体重可能会影响他们一生，和智商、身材、健康与否都有关!

Question

英国有一项研究，专门对近4千名1946年出生的男女进行追踪调查，调查的结果显示，智商和体重是正比的关系!出生的时候越重，成人后就越聪明，而体重偏低者各种认知功能都不如体重偏高者!也就是说5-8斤的正常体重之中，越接近8斤重的新生儿以后就会越聪明!而至于原因尚未清楚，科学家猜测是与新生儿的脑容量有关。

Being born at below-normal weight is associated with a lower intelligence quotient (IQ) not only in childhood and young adulthood but even at the age of 50, a new study from Denmark showed.

Researchers found IQ differences between underweight and normal-weight babies remained stable into midlife.

And even within the normal birth weight range, higher weights equated with slightly higher IQ throughout life.

Birth weights of less than 2.5kg have long been linked to a variety of health problems. A normal birth weight ranges from 2.5kg to 4kg, and the average weight of infants in the study was 3.3kg.

Compared to babies born at 2.5kg or under, infants with a birth weight of 3.5kg to 4kg scored more than five points higher on IQ tests at age 28 and again at 50, the study found.

Said lead study author Trine Flensborg-Madsen of the University of Copenhagen: "There are long-term cognitive consequences of birth weight that do not diminish."

8斤不超重吗之前还有专家说超过7斤会增加将来得糖尿病肥胖症的风险呢。遗传和后天喂养教育都很重要吧，在家等发动好无聊...希望小孩在6-7斤

楼主仔细看原文哦原文写的是把出生体重2.5及以下的和正常体重中3.5-4公斤的做比较，而不是把正常体重中偏轻的和偏重的做比较，所以那个中文翻译有误第二，只是比较体重没有考虑其他confounding factor，只能证明有association，不能证明causation

并没有错只是不完整。原文也说了And even within the normal birth weight range, higher weights equated with slightly higher IQ throughout life.我家娃出生也是很轻的，后天加油吧&hellip;&hellip;

是哦我也看漏了那一段，不过完全没有数据支持这一段，说明那个区别多半很小，应该都不是statistically significant总之这种文章一看就是来博眼球的，不必take it seriously
