In fact, if you compare the meta-analysis

that is done in the adult populations versus children
和孩子的元分析數據進行比較
in general there are stronger and more consistent associations

such that overall, the overall odds is almost 2 fold of
比如我使用了很多項不同研究的數據
I'm using a variety of studies, of a child being obese

And that's usually defined in the age specific threshold
這個結論以每個年齡段

Now, I'd like to review a few articles
接下來 我想回顧一下幾篇論文
that really hammer in that point a bit more
