What was studied

Three independent longitudinal cohorts (LonGenity, NECS, UK Biobank; combined n=4,030; follow-up up to 16–29 years) compared offspring of centenarians (at least one parent ≥100 years) with offspring of shorter-lived parents on age at death and onset of CVD, cancer, hypertension, and stroke, using Cox proportional hazards regression and meta-analysis.

Key findings

Centenarians' offspring had significantly lower hazards for death (HR 0.58; 95% CI, 0.41–0.81), CVD (HR 0.67; 95% CI, 0.46–0.97), and hypertension (HR 0.68; 95% CI, 0.62–0.75), with death delayed by ~3.1 years and hypertension onset delayed by ~5.2 years; stroke benefit was seen only in LonGenity and NECS; no cancer association was found.

Study limitations

- Cohorts differ in enrollment criteria, follow-up duration, and covariate availability, limiting direct comparability. - Observational design cannot establish causality; residual confounding by lifestyle and socioeconomic factors is possible. - Stroke and cancer results were inconsistent across cohorts, reducing confidence in those specific findings.

Clinical implications

Having a centenarian parent is associated with meaningfully later onset of cardiovascular disease and hypertension (by ~3–5 years) and lower mortality risk — supporting parental longevity as a useful criterion when recruiting participants for healthy-aging research. Clinicians can reassure patients with centenarian parents that their cardiovascular and longevity outlook may be meaningfully better than average.

Caveats

  • Study design is labeled 'cohort study with meta-analysis'; the meta-analysis component is based on only three cohorts, limiting its statistical power compared to larger formal meta-analyses.
  • The meta-analysis pools three cohorts with different enrollment ages, follow-up periods, and covariate sets, which may introduce heterogeneity not fully captured in aggregate HR estimates.
  • The stroke finding was inconsistent across cohorts (significant in LonGenity and NECS but not UK Biobank), and the cancer null result should be interpreted cautiously given potential follow-up length limitations.
