Mechanisms linking early life stress to adult health outcomes.

Abstract

Research relating stress to health has progressed from anecdotal evidence in the 1930s and 1940s to complex multivariate models that identify underlying longitudinal mechanisms. Enduring questions that have guided our research are: How does the early life environment affect health outcomes into adulthood? How is the latent damage stored and what processes are set into motion that link early life stress to health disorders in the later years? An emerging perspective focuses on the accumulation of interacting dysregulations in multiple physiological systems that compromise the systems' abilities to respond flexibly to stressful circumstances. Our research explores: the antecedents of these processes, including genetic predispositions, the harshness of the early environment, and their interaction; the mediating roles of neural regulation in the brain and psychological and social resources; and health-related outcomes, such as metabolic functioning and inflammatory processes.
