This study looked at leukocyte telomere length of three hundred eighty-seven women who gave birth to at least one child and lived to the top fifth percentile of their birth cohort, or died before the top fifth percentile of their birth cohort died, but were at least 70 years old. Significant association was found between the woman’s age at her last child’s birth and leukocyte telomere length. Women who were older than 33 when they gave birth to their last child were two to three times more likely to have telomere length in the highest 2 tertiles for telomere length. These findings suggest that giving birth later in life may be a marker for longevity.
