The Developmental Origins of Health and Disease (DOHaD) hypothesis posits that early life physiological stress has durable impacts on health and mortality risk across the life course. The implications of early life environment for long-term health trajectories remain a persistent challenge today that requires methodological approaches and theory building that reach into the past. Bioarchaeologists have recently begun to engage with the DOHaD hypothesis using various methodological approaches that focus on reconstructing early childhood stress, including linear enamel hypoplasia, vertebral neural canal size, stature estimation, and accentuated striae of Retzius. Bioarchaeological research has contributed to the broader framework of the DOHaD by exploring the impact of early childhood stress within various cultural contexts through deep time. However, bioarchaeological studies into the DOHaD hypothesis have encountered mixed results; some research demonstrates that early life stress is adaptive, making individuals more resilient and physiological competent in dealing with future stress, while other research shows that early life stress is linked with poor health and increased mortality risk in subsequent life history periods. Discrepancies in the link between early life stress and early death may be attributed to several factors, such as differences in methodological approaches, cultural factors, hidden heterogeneity in risk, and the type and severity of stress. This proposed symposium will explore the various factors that influence the interpretation of bioarchaeological research using the DOHaD hypothesis. This symposium will highlight the importance of cultural context and methodology, as well as novel theoretical approaches, in exploring the links between early life stress, future health, and mortality risk.
