The World Might Have Reached Peak Twin Now With More Twins Being Born Than Ever Before

Experts have said that more twins are being born than ever before. However, it might have reached peak twin, said the experts. Nearly 1.6 million twins are born every year across the world. As per the data, one in every 42 children born is a twin. As per the report, due to delayed childbearing and medical methods such as IVF, there has been an increase in the rate of twin births by a third since the 1980s. Now, health experts have claimed that it might be the downfall of this trend as the focus moves to one baby per pregnancy, which has low risk. Experts have said that as per a global overview, which has been published in the journal Human Reproduction, a peak twin might have happened due to a steep increase in the rate of twin births across all regions in the last 30 years. The rate of twin births has shot up by 32 percent in Asia and by 71 percent in North America. Scientists have extracted the data on the rates of twin birth from 165 nations from 2010 to 2015. Later, they have compared this data with the rate of twin birth from 1980 to 1985. They have found that the number of twins, born per thousand pregnancies has highly shot up now across Europe and North America. It has gone up from 10 per 1000 deliveries to 12 per 1000 deliveries around the world.

The rate of twin birth has been always on a higher side in Africa and it has not changed much in the past 30 years. It might be due to population growth. As per the data, Africa and Asia contribute to 80 percent of all twin deliveries in the world at present. Prof Christiaan Monden from the University of Oxford, who is the leading author of the study, has said that the rate of twin birth in Africa has been high as the birth of dizygotic twins, those are born out of two separate eggs is quite high in the continent. Most probably, it might be due to genetic variations in the African populations and other populations. The rate of twinning has been increasing in Europe, North America, and Oceanic nations as well said the author. A significant increase in the use of medically aided reproduction since the 1970s such as IVF, ICSI, artificial insemination, and ovarian stimulation has been playing a crucial role in the high rate of twin birth across these regions. These methods of reproduction increase the likelihood of twin birth. The study has shown that women choosing to plan their family later in life, an increase in the usage of contraception, and lower fertility overall as well play a big role in the birth of twin babies.

The lead author of the study has said that single baby delivery is safer as compared to a twin delivery. He has said that twin deliveries are linked to higher death rates in infants. It is linked to higher complications during pregnancy and after delivery for women and their babies. As per the study, twins are usually at a higher risk of complications at the time of birth and are more often born before the due date. Twins have lower birth weights as well. Twins are at a greater risk of stillbirth as well, said the experts. Experts have noted that the survival chances of twins in low and middle-income nations are a huge matter of concern. They have said that in Sub-Saharan Africa, more than 200000 twins are most likely to lose their co-twin in the first year of their life. Professor Jeroen Smits has said that the rate of twin birth in the rich western nations is going to be close to the rate of twin birth in Sub-Saharan Africa. However, there is a huge difference in the rates of survival. Experts have said that India and China will see a major surge in the rate of twin birth.
