When Penelope Chaney met up with her friend, Eleanor Marshall, she had good news to share—she was pregnant. But Eleanor also had good news—she was pregnant too. And amazingly, they both had been given the same predicted delivery date—April 4.So what are the chances of both giving birth on the same day?
In the UK, a woman’s estimated date of delivery is first calculated by using the date of her last period and adding 280 days, or 40 weeks. That is followed by an ultrasound scan where another estimate is made, based on the size of the fetus. If the two "due dates" differ by a week or more, the scan is taken as the more accurate measure.
It’s the same in most developed countries.
But data from the Perinatal Institute, a non-profit organization, show that an estimated date of delivery is rarely accurate—in fact, a baby is born on its predicted due date just 4% of the time.
The figure is higher when premature births and pregnancies with complications are not included, but only marginally (4.4%).
While it may be helpful for parents to get an idea of when their child will arrive, the main purpose of the due date is to " define a metric for the care" of the mother during pregnancy t says Prof. Jason Gardosi of the Perinatal Institute.
The advice to the expectant mother, he says, that the baby is likely to come any time between 37 weeks (259 days) and 42 weeks (294 days), a period referred to as " term," when the baby has reached full maturity.
For women like Penelope and Eleanor, whose pregnancies are low risk, 60% of babies are born within a week either side of the estimated date of delivery.
But, as noted above, only 4% are born on the predicted date itself—in other words, the chance of this happening is less than one in 20.
What, then, are the chances of Penelope’s and Eleanor’s babies both being born on April 4?
The chance that their children will be born on the same day—any day, not necessarily April 4—is higher. It’s about one in 30.
Gardosi says the statistics reveal an important message for pregnant women. The phrase "due date" is misleading, that makes it sound too accurate, he says—it should really be called an "estimated date. "
"Many mothers are unnecessarily anxious or impatient if there’s too much reliance on the expected date of delivery," Gardosi says.
Questions 16 to 18 are based on the recording you have just heard.
16.What is the ultrasound scan estimate based on?
17.What does the data from the Perinatal Institute show?
18.What is the main purpose of the due date according to Prof. Jason Gardosi?
选项
A、To reduce parents’ unnecessary anxiety.
B、To "define a metric for the coming" of babies.
C、To help parents know when their child will come.
D、To "define a metric for the care" of would-be mothers.
答案
D
解析
讲座中提到,Jason Gardosi教授说,虽然预产期对于父母了解孩子到来的日期可能会有帮助,但是预产期的主要目的是对照顾准妈妈定义一个度量标准。因此答案为D)。
