There are pronounced gender effects strongly favoring boys, although there are also effects for girls. Dynamic mediation analyses show a significant role played by improved childhood traits, above and beyond the effects of experimentally enhanced adult socioeconomic status. These results show the potential of early life interventions for promoting health.}, keywords={Abecedarian Project;randomized trial;social experiment;early childhood intervention;health;Perry Preschool Project}, }
