Universal Investment in Infants and Long-Run Health: Evidence from Denmark’s 1937 Home Visiting Program
研究了丹麦1937年家访计划对婴儿的长期健康影响，发现接受干预的人在中年时期生存率更高、住院更少、心血管疾病风险更低。
This paper examines the long-run health effects of a universal infant health intervention, the 1937 Danish home visiting program, which targeted all infants. Using administrative population data and exploiting variation in the timing of implementation across municipalities, we find that treated individuals enjoy higher age-specific survival rates during middle age (45–64), experience fewer hospital nights, and are less likely to be diagnosed with cardiovascular disease. These results suggest that an improved nutrition and disease environment in infancy “programmed” individuals for lower predisposition to serious adult diseases.
