Increasing number of long-lived ancestors marks a decade of healthspan extension and healthier metabolomics profiles

Globally, the lifespan of populations increases but the healthspan is lagging behind. Previous research showed that survival into extreme ages (longevity) clusters in families as illustrated by the increasing lifespan of study participants with each additional long-lived family member. Here we investigate whether the healthspan in such families follows a similar quantitative pattern using three-generational data from two databases, LLS (Netherlands), and SEDD (Sweden). We study healthspan in 2143 families containing index persons with 26 follow-up years and two ancestral generations, comprising 17,539 persons. Our results provide strong evidence that an increasing number of long-lived ancestors associates with up to a decade of healthspan extension. Further evidence indicates that members of long-lived families have a delayed onset of medication use, multimorbidity and, in mid-life, healthier metabolomic profiles than their partners. We conclude that both lifespan and healthspan are quantitatively linked to ancestral longevity, making family data invaluable to identify protective mechanisms of multimorbidity. Although human life expectancy has been increasing, time spent in good physical and cognitive health has not been rising at similar rate. Here, the authors show that both lifespan and healthspan are quantitatively linked to ancestral longevity, and that those from the longest-lived families have a healthier metabolomics profile before the onset of disease, highlighting the important role of the family in healthy survival.

Automated summary

Globally, the lifespan of populations is increasing, but the healthspan is not keeping up. Research shows that longevity runs in families, with each additional long-lived family member increasing the lifespan of study participants. This study investigated whether the healthspan in such families follows a similar pattern and found that an increasing number of long-lived ancestors is associated with up to a decade of healthspan extension. The study also found that members of long-lived families have delayed onset of medication use, multimorbidity, and healthier metabolomic profiles than their partners.
