Social Determinants (Beckfield and Krieger, 2009) “Contextual factors such as political systems and government policies drive population health and health inequities.”
Social Determinants • In addition to political systems: • Economic systems • Social institutions (public schooling, Medicare) • Physical Environment (built environment) • Social Environment (culture, war, racism)
Social Determinants Hurricane Katrina, 2005 And of course, these can work in tandem.
Health Inequity Also called health disparity Social determinants create inequities because populations are effected differently We can see this both on a local and a global scale
