You're likely to live longer if one of your parents has a rare trait

Key Points:

• A new study published in JAMA Network Open found that offspring of centenarians—people who live past 100—experience delayed mortality and reduced risk of age-related diseases such as cardiovascular disease, high blood pressure, cancer, and stroke.
• The research analyzed data from over 4,000 participants aged 65 to 74 across three cohorts in the US and UK, comparing those with at least one parent who lived to 100 versus those whose parents died by age 73.
• Children of centenarians showed significantly lower risks of early death and age-related illnesses, supporting the idea that longevity traits may be inherited and linked to healthier aging.
• Centenarians, who make up only 0.03% of the US population, often develop age-related diseases much later than average, and their unique molecular aging patterns provide valuable insights into genetic and environmental factors promoting longevity.
• This study emphasizes the importance of centenarians as a model for understanding healthy aging and suggests that lifestyle and genetics both play critical roles in extending lifespan.
