(原po只是英文兼職譯者，剛好看到此文，
又剛好有個自閉症女兒，剛好是剖腹產，所以略翻譯一下跟大家分享。
若有誤請專業人士指正。)
簡要大意
"The study, ... a meta-analysis ... found that birth by cesarean section was
associated with a 33 percent higher risk of autism and a 17 percent higher
risk of attention deficit disorder. The increased risk was present for both
planned and unplanned cesarean deliveries."
查看以前的研究發現，無論是自願或非自願剖腹，
剖腹產出生有33%較高的風險罹患自閉症，17%較高的風險罹患注意力缺陷。
And let me say again ... we can’t say cesarean section is causing this,”
Ms. Zhang said. “We did find the association, which means further studies
are needed.” However, she said, “Women shouldn’t be hesitant about
cesarean sections when they are medically indicated.”
作者最後強調，只是發現剖腹產與自閉症有關，但不表示是因果關係。
需要更多研究釐清。
若醫生建議剖腹產，產婦不應遲疑是否要剖腹。
