Mommy with twins will live longer

Women who deliver twins live longer compared to moms of only singletons, a new study has claimed.

According to the University of Utah study, it's not that doubling up on dirty diapers boosts their life span, but instead that healthier women have an increased chance of delivering twins.

"Having twins will not make you stronger or healthier, but stronger, healthier women are more likely to have twins naturally," Shannen Robson, the study's first author, said.

Ken Smith, the senior author of the study, added: "The prevailing view is that the burden of childbearing on women is heavier when bearing twins. But we found the opposite: women who naturally bear twins in fact live longer and are actually more fertile."
The research, published in the journal Proceedings of the Royal Society B, was based on genealogical record of over 58,780 non-polygamous Utah women who were born between 1807 and 1899, lived to age 50 and married for once. Of those, 4,603 were the mothers of twins and 54,183 gave birth only to one baby at a time.

It was found that mothers of twins beat moms of only singletons on every measure - they lived longer, had longer reproductive life spans, needed less time to recover between pregnancies, and had more children overall.

While mothers of twins born before 1870 had on average 1.9 more children than mothers of singletons in their age group, the moms in the post-1870 group each had 2.3 kids more than their singleton mom counterparts, the researchers found.

Because twins have a higher likelihood of death than singletons, the researchers adjusted that finding by infant mortality, assuming that a mom of twins might have more babies faster after a child died. Even after that adjustment, moms of twins came out ahead, having 1.24 to 1.56 more kids than singleton-only moms.

Smith said: "There are so many factors that contribute to longevity, health and ageing. This study has been able to identify another important factor that contributes to health and longevity in later years, namely, that women bearing twins appear to be healthier."

"That innate healthiness is contributing to their ability to have twins, and it is also contributing to their longevity," he added.

However, Smith emphasised that their study looked at women who lived past menopause, not those who died earlier, perhaps in childbirth.

"We do know women who have twins, triplets and so on do have medical complications and their health is sometimes compromised. But we are talking about the long view," he said.

The vast majority of those women in the study reached the age 50, and that is why "we're able to observe that they have healthier lives", he noted.

For women today who have access to infertility treatment and who have twins - which isn't uncommon, the researches said they "simply don't know how that will affect their health
