這項研究無法判斷是否是嬰兒時期的問題導致了日后的行為問題：它們也可能是日后其他一些問題的早期癥狀。
The foetal development of boys may also be more sensitive to this kind of chemical assault, the authors speculate, which could explain why boys are more likely to have behavioural problems than girls.
該報告的作者推測，男孩在胎兒發(fā)育階段可能對此類化學襲擊反應更為敏感，這就可以解釋為什么男孩比女孩更有可能出現(xiàn)行為問題。
