Chinese children are much taller and stronger than four decades ago, with the height gap standing at 8 centimeters (cm), a government survey showed Wednesday.

The National Health and Family Planning Commission (NHFPC) surveyed 161,774 healthy children under seven years old from nine cities and their suburbs in 2015. Health authorities have conducted the survey once every 10 years since 1975.

Taking children aged 5 to 5.5 for example, the boys on average measure 113.6 cm, 8 cm taller than boys in 1975 and 1.7 cm taller than boys in 2005, while girls have an average height of 112.5 cm, 8.2 cm more than four decades ago and 1.8 cm more than ten years ago, according to the 2015 survey results.

They also weigh 3.7 to 3.28 kilograms more than children four decades ago, the survey showed.

The physical development of the children surveyed surpassed the World Health Organization's child growth standards, according to the NHFPC.

The weight and height gaps between urban children and rural children have also narrowed, according to the survey.

In 1975, urban boys aged four to five were on average 4-cm taller than their rural peers, but the gap was only 0.6 cm in 2015, while for girls of the same age the difference dropped from 4.3 cm to 0.4 cm.
 
整个动物界的规律:食物充足时身体就高大。
工业革命前欧洲人比中国人矮很多,工业革命后食物充足了营养比中国人好了欧洲人身高逐渐超过中国人。
 
前几天door open,去了几个老房子看看,里面的床又窄又小。和里面的人聊起来,过去的人就是矮小,营养的关系。
 
这不奇怪,现在的孩子普遍比父母个子高。营养好了呗。
 
以前母乳喂养多,孩子个头长得慢,但是后来冲刺。
现在配方奶多,孩子头几年发育快,但一定年龄就长不快了。

不过为啥南方人普遍比北方人矮呢?南方人没有牛奶喝?

南方天气炎热,人吃的少。
北方天气爽,吃的多。
还有一点北方一般阳光充足,不缺钙就容易长高。
 
小日本 是不是长得更多?
 
是这样啊。
我的几个在这边出生长大的表兄弟都比我高至少5 cm。他们父母都比我父母矮的。
我70-80年代我们婴儿时期都没这么多formula的,很早就吃米汤和米糊了。我个人认为吃面比吃米要高大,吃肉和马铃薯多的更高大。我们国人就是米吃得多,肉吃得少,几乎没有人用马铃薯做主食的。
 
60年代初出生的都比较矮小,连普遍身高还可以的北京人都这样,“三年自然灾害”,没饿死就不错了。说明一个人的身高和体质,孩提时代的营养决定因素很大。再早出生的比如40-50后,十几岁时饿一下子,事后还能缓过来,60后就没戏了。
