This research review explores the profound and lasting impact of early-life shocks, such as maternal and child undernutrition, exposure to epidemics like the Spanish and Hong Kong flu, and conflict, on adult health and human capital development. It examines how these adverse experiences, particularly during critical developmental windows, can lead to reduced educational attainment, diminished economic productivity, and increased susceptibility to chronic diseases in adulthood. The document highlights the intergenerational transmission of poverty and poor health, emphasizing that interventions targeting early childhood are crucial for breaking these cycles. It draws upon a wide range of studies, including those from Sub-Saharan Africa, to illustrate the correlation between childhood adversity and negative adult outcomes, such as lower income, increased risk of domestic violence, and reduced educational attainment. The review also touches upon the economic consequences of climate shocks and their association with increased household income volatility and reduced expenditure on food and education. Furthermore, it discusses the long-term health consequences of severe deprivations, linking them to the increased prevalence of chronic illnesses in later life and the economic burden they impose on individuals and societies. The paper advocates for a comprehensive approach to child development that addresses various forms of early-life adversity to foster healthier, more productive adult populations and enhance overall human capital.
