Adapted social determinants of health framework from (Barton and Grant, 2006) as first proposed by (Dahlgren and Whitehead, 1991) to visualize the role of how the natural and built environment are part of a larger complex process by which health and well-being are affected. Health outcomes, such as brain and cognitive development as measured in the ABCD Study, is influenced by a set of multi-faceted and interlocking factors, running from the broad physical environment (green) through more proximal measures including social environment, lifestyle factors (blue). For the physical environment, the LED Environment Working Group is tasked with identifying and linking residential geocodes to various external databases in hopes of characterizing these natural and built environmental contextual variables in the ABCD Study. Categories of the various existing types of environmental factors already linked to each child’s baseline residential address are illustrated in green and blue bubbles and correspond with those datasets described in detail in Table 1. Gray bubbles are planned natural environmental variables that will be linked in the future. Figure created with BioRender.com
