Drs. Leonid Gavrilov and Natalia Gavrilova reported that the chances of being alive up to the ripe old age of 100 and above is double for a child born to a woman below the age of 25 years. The father's age is less significant for longevity.
In a previous study, they had identified that first-born children, especially daughters, have more chances to live up to the age of 100.
They found that although being born to a young mother was an important predictor of longevity, other factors seem to help, such as, growing up in the Western part of the U.S., spending part of one's childhood on a farm, and being born first.
"The finding that children born to young women are more likely to live to 100 may have important social implications," Gavrilov said, "because many women postpone their childbearing to later ages because of career demands."
The researchers emphasize that further study is required .
