Abstract

The pervasive effects of early childhood experiences on health at older ages, documented with methods from life course epidemiology, have served to refocus many public health efforts towards understanding the impact of both cumulative disadvantage and what are known as "sensitive periods" and "critical periods" in shaping health trajectories. While the impact of early childhood experiences has been well-studied, much less attention has been focused on other periods of the life course that might also serve as critical junctures in shaping exposures and risks, periods that may also influence biological pathways leading to poor health in late life. This is especially important as we examine social and economic...
