Survival of Parents and Siblings of Supercentenarians

摘要

BackgroundGiven previous evidence of familial predisposition for longevity, we hypothesized that siblings and parents of supercentenarians (age ≥ 110 years) were predisposed to survival to very old age and that, relative to their birth cohorts, their relative survival probabilities (RSPs) are even higher than what has been observed for the siblings of centenarians.
