Researchers have revealed something interesting that more twins are being born than ever before this year.
Seeing the increasing number of twins being born, researchers say that the world may now see the ‘peak twin’.
According to the international news agency, around 1.6 million twins are born each year worldwide, and one in every 42 children born a twin. The rate of twins births has increased by a third since the 1980s probably due to delayed childbearing and medical techniques such as IVF.
What do the researchers say?
According to a global overview in the journal Human Reproduction, the peak increased because of large increases in twinning rates in all regions over 30 years – from a 32% rise in Asia to a 71% rise in North America.
Data on twinning rates from 165 countries were collected by the researchers from 2010 to 2015. They then compared the data with rates from 1980 to 1985.
The study says that the number of twins born per thousand deliveries is now greater in Europe and North America. The number has gone from nine per 1,000 deliveries to 12.
On the other hand, twin rates in Africa have always remained high for the past 30 years.
Prof Christiaan Monden, the study’s author from the University of Oxford, said there was a reason for that.
“The twinning rate in Africa is so high because of the high number of dizygotic twins – twins born from two separate eggs – born there,” he said.
“This is most likely to be due to genetic differences between the African population and other populations.”
