Research suggests that later reproductive ages lead to longer lifespans

Reported by Reference News on July 17thAccording to the website of New Scientist on July 14th, women who give birth later have a longer lifespan than those who give birth earlier. Those who are able to conceive and give birth at an older age may have overall good health and therefore a longer life expectancy.

In order to better understand the link between overall health and reproductive health, and how this link changes with age, Niels van den Berg of the Leiden University Medical Center in the Netherlands and his colleagues analyzed more than 11500 women in two existing studies. These women all lived to be over 50 years old and had at least one child without using assisted reproductive techniques such as in vitro fertilization. This does not include transgender individuals.

Researchers have found that women who give birth to their last child at an older age live longer. Overall, for every additional year of age at the end of childbirth, life expectancy increases by 22 days, and statistical analysis shows that this is not an accidental phenomenon.

After comparing women aged 40 or below who gave birth to their last child with women aged 45 or above who gave birth to their last child, they found that the average lifespan of the latter was 17 months longer. Taking into account all the risk factors for death, the 1.41 year difference can be said to be quite significant, "Vandenberg said

Previous studies have shown that giving birth at or above the age of 40 increases the risk of complications, such as those affecting the blood and immune system, compared to women who give birth under the age of 40. But Vandenberg said that women who give birth later may live longer because they are generally healthier, which not only prolongs their lifespan but also enables them to conceive at an older age.

However, the longevity of parents or other relatives is not related to women giving birth later. Researchers suggest that this suggests that their reproductive health may be not only related to genetics, but also to their lifestyle.

Vandenberg said, "Other factors that contribute to longevity may also have an impact on reproductive health." However, he added that the team cannot rule out the role of genetics and further research is needed to analyze this in depth.

Jennifer Garrison of the Global Alliance for Reproductive Longevity and Equality in Novato, California, said it is unclear at what age women will have their last child and why it will affect lifespan. She said that a better understanding of the mechanisms driving this association may have profound impacts on women's health.
