TORONTO — While being mother is a greatly gratifying experience, most mothers are unlikely to consider the sleepless nights and temper tantrums as beneficial for aging. But, a surprising new study suggests that the more children a woman has, the slower she ages.
In the journal PLOS One, researchers reveal that women who had more children had longer telomeres than women who had fewer children.
The researchers assessed the number of children born to 75 women from two neighboring indigenous rural Guatemalan communities. In addition, they assessed the length of their telomeres at two time periods 13 years apart.
They found that producing a higher number of offspring may actually slow the pace of biological aging. The findings reveal a bit more about the process of aging and how estrogen may influence women.
“The slower pace of telomere shortening found in the study participants who have more children however, may be attributed to the dramatic increase in estrogen, a hormone produced during pregnancy,” said Pablo Nepomnaschy, one of the researchers, in a news release. “Estrogen functions as a potent antioxidant that protects cells against telomere shortening.”
With that said, the social environment in which the study participants live may influence the relationship between their reproductive efforts and the pace of aging.
“The women we followed over the course of the study were from natural fertility populations where mothers who bear numerous children receive more social support from their relatives and friends,” said Nepomnaschy. “Greater support leads to an increase in the amount of metabolic energy that can be allocated to tissue maintenance, thereby slowing down the process of aging.”Follow @gorkhapost
