Mothers of Twins Live Longer According To Research Study
A study published by the Proceedings of the Royal Society B says that mothers of twins are more likely to live longer than mothers that have only one baby at a time.
According to the report by Live Science about the research, mums of twins usually have live longer because they are physically stronger in the first place, since giving birth to two babies requires more strength.
"We expected the exact opposite," researcher Shannen Robson of the University of Utah told LiveScience. "We expected that since most humans have one baby at a time, having two would be really burdensome ... Twins are an identifier of these women who are remarkable, physically exceptional people."
The research focused on the genealogical record of female Utah residents from 1807 to 1899 who were not widows, part of polygamous families, and lived to be at least 50 years old. The researchers were able to identify 4,603 women who had at least one set of twins and compared them with those who did not give birth to twins.
Research findings show that mothers of twins beat those without twins in different categories such as life span, reproductive life span, and faster recovery time between pregnancies.
"By identifying them, we can then look at other aspects of what it is about them that makes them more healthy, live longer and have babies at a faster rate than everyone else in the population," Robson said in an interview.
According to Family Education, identical twins -- or twins that have the same genes and sex -- are conceived when one fertilized egg splits into two separate cells. On the other hand, non-identical twins -- or twins that do not have the same genes and can be of a different sex -- are conceived when two eggs are released at ovulation.
Live Science says that the findings seem to suggest that moms of twins "could be an evolutionary adaption in which healthy moms take the chance to pass on double their genes at once".
