People worry that using tools to pull the baby out (in a vaginal birth) may affect their brains.

人们担心(在自然分娩中)用工具把婴儿拖出来可能会影响婴儿的大脑。

"The relative safety of the operation leads people to think it's as safe as vaginal birth," said Dr. A. Metin Gulmezoglu, who co-authored the Asia report.

“手术的相对安全性致使人们认为剖腹产和顺产一样安全，”亚洲报告作者之一A . Metin Gulmezoglu博士说。

A previous study by the same team of researchers found that vaginal births double the rate of pelvic floor disorders, compared to Caesarean deliveries or never giving birth.

同一研究小组在先前的一项研究中发现：跟剖腹产或从来未生育过的妇女相比，通过产道分娩的妇女盆底疾病患病率要高出一倍。

"Small bleeds in and around the brain are very common in infants who are born vaginally," Dr. Gilmore said. "It seems that a normal vaginal birth can cause these small bleeds."

Gilmore博士讲到，“产道出生的婴儿颅内出血相当常见，看来是正常产道生产造成的”。
