Predicting Older Age Mortality Trends
研究发现，1900至1960-80年间，60-79岁人群十年死亡率下降中至少16-17%归因于早期产前和产后条件的改善。历史趋势表明，婴儿潮一代可能比过去更长寿，但1955年后出生队列的死亡率下降幅度可能不如早期队列。
Improving early prenatal and postnatal conditions account for at least 16 to 17 percent of the decline in ten year mortality rates of 60-79 year olds between 1900 and 1960-80. Historical trends in early prenatal and postnatal conditions imply that while the baby-boom cohort may be particularly long-lived compared to past cohorts, mortality rates may not fall as steeply for the cohorts born after 1955 as for earlier cohorts.
