Living to 100 may benefit more than one generation. Children of centenarians tend to live longer while delaying major threats to heart health, new large analysis reveals. Study published in JAMA Network Open found adults with at least one parent who lived to 100 had substantially lower risks of death, cardiovascular disease, and hypertension than people whose parents had shorter lives.
Several outcomes also occurred years later, suggesting exceptional longevity may involve extended period of healthier aging rather than survival alone.
Led by researchers at Albert Einstein College of Medicine, Boston University, and Tufts Medical Center, work strengthens evidence that unusually long and healthy lives cluster within families.
Lifestyle remained important, but it did not fully account for advantages observed among centenarians’ children.
“Centenarians—people who live to age 100 or older—offer crucial insights into what it looks like to age well,” said Sofiya Milman, M.D., M.S., professor of medicine and of genetics at Einstein, vice chair for research in medicine, and senior author.
“We wanted to know whether they pass their good health and longevity down to their children—and, if so, whether those advantages can be explained by healthy habits or whether something more fundamental, like genetics, is at work,” Milman explained.
Three Studies Track Exceptional Longevity Across 5,000 People
Researchers combined evidence from three geographically diverse, long-running projects: Einstein-led LonGenity study, New England Centenarian Study, NECS, at Boston University, and UK Biobank.
Together, analysis included 2,319 adults with at least one centenarian parent and 2,703 controls. Control participants either had parents who lived to age 85 or younger or were spouses of centenarians’ offspring.
Including spouses gave researchers useful comparison group because couples often share environments and health habits but not same inherited biology.
Available data covered 16 years in LonGenity and UK Biobank and 29 years in NECS. Although studies collected information independently, team analyzed each group using same approach. This allowed researchers to determine whether associations with death and age-related disease appeared consistently across different populations.
Lower Risks and Later Disease: 42% Lower Death, 33% Lower CVD
At any given age, people with centenarian parent had 42% lower risk of death than participants whose parents had shorter lifespans. Their risk of cardiovascular disease was 33% lower, while risk of hypertension was 32% lower. Timing of outcomes was also notable. Centenarians’ offspring died approximately three years later on average and developed hypertension about five years later. Delaying common condition such as high blood pressure could have wider health implications because hypertension contributes to heart, blood vessel, kidney, and brain disease.
Benefits remained largely consistent after researchers accounted for smoking, alcohol consumption, exercise, diet, education, and socioeconomic status. Findings therefore suggest familiar health behaviors and social circumstances do not completely explain why exceptional longevity runs in certain families.
Analysis: Protection Has Clear Limits – No Lower Cancer Risk
Having centenarian parent did not provide equally strong protection against every disease. Stroke risk was reduced only in LonGenity and NECS studies, not consistently across all three groups. Cancer risk was no lower among centenarians’ offspring, result that agrees with some earlier research. Therefore, longevity advantage appears specific to cardiovascular and mortality protection.
“The overall consistency of these findings across these quite different studies was especially noteworthy and reinforces idea that exceptional longevity runs in families,” said Eric Reed, Ph.D., staff scientist in medicine and lead author.
“This is not to say that lifestyle doesn’t count—healthy behaviors remain important for everyone. But some people from families with exceptional longevity appear to enjoy biological advantages that help them remain healthy despite environmental and behavioral factors that affect us all,” Reed added.
Turning Longevity Biology Into Treatments For Everyone
“This study wasn’t designed to identify specific inherited traits that benefit centenarians’ children,” Dr Milman said. “However, studying families with exceptional longevity can provide unique window into biology of healthy aging.” “Our findings provide strong rationale for studying centenarians and their families to uncover those biological factors that promote longevity and protect these individuals from age-related diseases,” she explained.
“Ultimately, discovering those factors could lead to treatments that mimic effects of naturally occurring longevity mechanisms, potentially helping people who did not inherit exceptional longevity to live longer and healthier lives,” Milman added.
“This study provides strong evidence that offspring of centenarians share some of their parents’ advantages in healthy aging,” said study co-author Paola Sebastiani, Ph.D., director of Center for Quantitative Methods and Data Science at Tufts Medical Center.
“These findings bring us closer to understanding biological factors that may help protect against age-related disease and promote longer, healthier lives,” Sebastiani concluded.
Q&A
Q: Do children of centenarians live longer?
A: Yes, JAMA Network Open study found adults with centenarian parent had 42% lower risk of death and died about 3 years later on average than controls.
Q: Do centenarians’ children have less heart disease?
A: Yes, they had 33% lower cardiovascular disease risk and 32% lower hypertension risk, with hypertension occurring 5 years later than in controls.
Q: Is longevity from lifestyle or genetics?
A: Benefits remained after accounting for smoking, diet, exercise, alcohol, education, and socioeconomic status, suggesting genetics and biology beyond lifestyle.
