Fewer women than average give birth on Halloween and more do on Valentine's Day,according to a U.S.study that questions whether women can control the timing of delivery.
For the study,researchers analyzed almost 2.5 million birth certificates for the week before and after the two holidays between 1996 and 2006.
On Halloween there was a 5.3 per cent decrease in "spontaneous" or vaginal births and a 16.9 per cent decrease in cesarean births,compared with other births occurring within one week before and one week after the October holiday.

答案和解析
美国一项关于女性是否能够控制分娩时间的研究表明,比起情人节,在万圣节分娩的女性数量少于平均水平.
研究中,研究人员对 1996 到 2006 年间这两个节日前后两周的约 250 万的出生证明进行了分析.
万圣节时,“自然分娩”(顺产)人数比该节日前后周的数据有百分之 5.3 的下降,而破腹产的人数下降达百分之 16.9.
