剖腹产的婴儿死亡率高于自然生产

News Background

新闻背景　　

美国心理学家弗赫于多年前公布的研究结果：分娩方式可能决定着孩子的未来。弗赫经长期研究发现，分娩的过程尽管相对于孩子一生来看是极为短暂的，但这一过程将影响一个人未来的性格、脾气和气质。弗赫的研究，引起了西方医学界，尤其是妇产科、儿科专家和心理学家们的关注，并就此作了大量的调查研究后，不仅证实了弗赫的观点，而且还有许多新的发现。正常分娩的婴儿比未经历分娩过程的剖腹婴儿肺容量大且较少患呼吸系统疾病；正常儿童弱视发病率仅为4%，而受钳产、剖宫产、臀位产等各种方式难产儿童的弱视率却高达15%以上。

News Transcript VOA 新闻梗概

A World Health Organization survey of hospital and clinic births in nine Asian countriesearlier this year found 27 percent were c-sections, and in China it was nearly half of all births.

And there were more deaths and complications when women had a cesarean delivery that wasn’tmedically required.

Now, a small but intriguing new study looks at one way the delivery method might affectthe baby’s health. Co-lead author Elizabeth Costello, now at Stanford, was at the University ofColorado when the study was done.

The researchers suspect that the newborn c-section babies might be picking up their genericbacteria mix from the air - one way bacteria gets on our skin.

Exactly how the differences in bacteria might make vaginally born babies less prone toallergies and asthma isn’t yet clear, but it does point to a difference that researchers can look atgoing forward. Costello says she expects more studies as DNA analysis gets cheaper and faster.

“I think further studies will be necessary to show whether the differences we’

ve demonstrated depending on delivery mode of babies when they fi rst emergeinto the world actually carry over time, and whether those differences mightcontribute to health outcomes.”

Elizabeth Costello’s paper is published online by the Proceedings of theNational Academy of Sciences.
