how do you do, guys and gals, Trace here for DNews, and I think we can all agree puberty is terrible.
大家好,我是Trace,欢迎大家收看本期的DNews,我想,我们应该都会觉得青春期很烦人吧。
you want to start like talking to girls, and your voice gets all crackly Havers Janice.
你正想跟女生说说话,你的声音却把所有人都给惊到了。
or maybe you want boys to notice how nice you look, and your body's going through all these weird changes and acne is popping up and awkwardly sized.
又或者你希望男生们能注意到你有多好看,结果你的身体却发生了各种奇怪的变化,痘痘也开始冒出来,还大得让人尴尬。
Everything.
这类问题简直不胜枚举。
Now, a long-term study following 1,200 girls in New York Chicago in San Francisco has some troubling results.
针对纽约,芝加哥,旧金山1200名女生的一项长期研究得出了一些令人不安的结果。
Girls are starting puberty younger than ever before. And we don't really know why.
如今,女生们进入青春期的时间比以往任何时候都要早。这背后的原因我们还不清楚。
The study published in the journal Pediatrics explains that in the 1990s African American girls were developing breasts at about age nine.
发表在《儿科学》杂志上的这项研究解释说,在20世纪90年代,非裔美国女孩胸部开始发育的时间是9岁左右。
Hispanic girls were a few months later.
拉美裔女孩要晚几个月。
And while white and Asian girls began developing breasts at about nine and a half.
白人和亚洲女孩则是在九岁半左右开始胸部发育。
Today they show girls are developing breasts four months earlier than in 97.
研究人员们发现,如今,女生的胸部发育时间较97年提前了四个月。
And that is a huge change over such a short time.
就这么短的时间来看,这一变化可谓十分迅速了。
So why this time shift? Obesity, really.
问题是,为什么会出现这种时间上的变化呢?原因就是肥胖,真的。
According to the researchers, they write that heavier girls start puberty earlier,
研究人员写道,身体较胖的女生进入青春期的时间也会更早,
but added that there are literally hundreds of chemicals which could be causing this shift.
但他们也补充说,实际上能引起这种变化的化学物质有数百种。
Other experts weighed in claiming obesity was unlikely to be the only cause,
其他专家也称肥胖不太可能是女生青春期提前的唯一原因,
and that where girls live and how much meat and dairy they have in their diet will also affect puberty onset,
生活的地方,以及饮食中肉和乳制品的含量也会影响女生进入青春期的时间,
even family stress has changed pubertal timing.
就连家庭压力也是改变青春期开始时间的因素之一。
Some of the more sensationalized chemicals known to cause estrogen activation are BPAs or bisphenol A, found in some plastic drink bottles,
一些已知会激活雌激素并且比较耸人听闻的化学物质是一些塑料饮料瓶里含有的BPA,也即双酚A,
and 34 of the 200 NIH tested pesticides contained estrogen mimicking compounds.
以及200种经过NIH测试的含有类雌激素化合物的农药中的34种农药。

Chemicals on furniture like brominated flame retardants can be absorbed through the skin, and could be yet another cause of this.
家具上的化学物质,溴化阻燃剂等,也可以通过皮肤被人体吸收,从而变成导致女生青春期提前的又一原因。
Again, literally hundreds of chemicals and we don't know.
重申一下,影响青春期开始时间的化学物质的种类数以百计,我们也不知道究竟是哪一种引起的。
In the past, there have been stories about hormones in the water supply.
过去有传闻说我们的自来水里也有激素。
It seems to have hit the presses in the late Ott's, focusing on how hormones from birth control pills were finding their way back into our kids and food sources.
这种说法似乎是在OTT服务后期开始出现在媒体上的,主要说的是避孕药中的激素是如重新回到我们的孩子身上以及我们的食物来源里的。
In reality, a study in 2011 found otherwise sewage treatment plants remove virtually all EE2 - which is the main estrogen founded contraception.
事实上,2011年的一项研究发现,污水处理厂以及已经过滤了所有的EE2——避孕药里发现的主要激素。
But cattle are given five times the dosage,
但牛肉里的剂量相当于避孕药里的5倍,
and hormones like plant estrogen, known as phytoestrogen, are found in soy products, nuts, grains, and meats, which then brings us all the way back to diet.
而植物雌激素等激豆类食品、坚果、谷类和肉类里都有,这样一来,雌激素又重新回到了我们的膳食里。
Some blogs are reporting moms being more stringent with their kids meat and dairy, to eliminate at least that source of possible contamination.
一些博客写道,妈妈们对孩子摄入的肉类和乳制品的控制已经更加严格了,以便除掉至少这一种可能的“污染”来源。
Regardless though, the obesity and diet factors are major.
尽管如此,肥胖和饮食仍是女生青春期提前的主要因素。
And many of the experts agree on that, with all agreeing that more research is needed and fast.
而且,许多专家都同意这一点,但所有人都一致认为还迫切需要更多的研究。
So what can science do about this really?
那么,科学究竟能做些什么呢?
For the moment, nothing.
从目前来看,什么都做不了。
Because we don't know what's causing it.
因为我们根本就不知道真实的原因是什么。
But what do you think about studies like this?
你们对这些研究有什么看法呢?
Are we just evolving to be more mature younger? Or are we missing something in our food regulations?
我们是在往更早成熟的方向发展呢?还是我们在食品管理环节出了什么纰漏呢?
