Predictors of Exceptional Longevity: Effects of Early-Life and Midlife Conditions, and Familial Longevity

摘要: Knowledge of strong predictors mortality and longevity is very important for actuarial science practice. Earlier studies found that parental characteristics as well early-life conditions midlife environment play a significant role in survival to advanced ages. However, little known about the simultaneous effects these three factors on longevity. This ongoing study attempts fill this gap by comparing centenarians born United States 1890-1891 with peers same years who died at age 65. The records controls were taken from computerized family histories, which then linked 1900 1930 U.S. censuses. As result linkage procedure, 765 confirmed 783 obtained. Analysis multivariate logistic regression existence both general gender-specific human General common men women are paternal maternal Gender-specific male occupation farmer 40, Northeastern region birth States, second half year.

Given importance familial an independent ages, we conducted comparative biological nonbiological relatives using larger sample 1,945 validated 1880-1895.

Wives (who share lifestyle living conditions) have significantly better wives centenarians' brothers. finding demonstrates shared results suggest background, some
