While late pregnancies are often flagged for risks to mother and baby, emerging research highlights a surprising benefit: women delivering their last child after age 33 tend to outlive those whose youngest arrived before 29.
Researchers drew from the Long Life Family Study database, examining over 300 women who reached at least 95 years old. Key finding: those with a final pregnancy after 33 were twice as likely to hit that milestone. Columbia University experts link this to telomeres—DNA caps shielding chromosome ends. Longer telomeres offer better cellular protection and longevity. Among late mothers, 35.7% had the longest telomeres, compared to 20% in the earlier group. Crucially, no causal link is established—don't base family planning on this research.
