Socioeconomic disadvantage and social adversity during early childhood substantially increase risk for adulthood obesity. The results of the proposed study will provide evidence on the pathways (e.g. diet, physical activity, smoking, education, depressive symptomatology, mindfulness and epigenetic methylation patterns) that may link early life adversity to adulthood obesity. This evidence will inform society on anticipate benefits of adulthood interventions on these pathways to reduce the long-term consequences of early childhood adversity on obesity.
