Infant Health and Longevity: Evidence from A Historical Intervention in Sweden
研究了1930年代瑞典一项提供婴儿护理信息、支持和监测的干预项目，发现婴儿期干预降低了婴儿死亡风险和75岁前死亡风险。
This paper investigates the potential of an infant intervention to improve life expectancy, contributing to emerging interest in the early life origins of chronic disease. We analyse a pioneering program trialled in Sweden in the 1930s, which provided information, support and monitoring of infant care. Using birth certificate data from parish records matched to death registers, we estimate that the average duration of program exposure in infancy led to a 1.54% point decline in the risk of infant death (23% of baseline risk) and a 2.37% decline in the risk of dying by age 75 (6.5% of baseline risk).
