; and economic stability. (B) The following examples illustrate the nexus between the unequal distribution of the social determinants of health and health disparities: (i) The built environment influences residents’ level of physical activity. Neighborhoods with high levels of poverty are significantly less likely to have places where children can be physically active, such as parks, green spaces, and bike paths and lanes. Neighborhoods and communities can provide opportunities for physical activity and support active lifestyles through accessible and safe parks and open spaces and through land use policy, zoning, and healthy community design. (ii) Emotional and physical health and well-being are directly impacted by perceived levels of safety, such as unlit streets at night. Community members have expressed that safety is not only a barrier to accessing programs and services that increase quality of life but they are also not able to access physical activity in their community through the built environment. (iii) In many workplace environments. (iv) Historical and institutional racism in the United States has shaped the way in which social and economic resources and exposure to health promoting environments are distributed. Income, education, occupation, neighborhood conditions, schools, workplaces, the use of health and social services, and experiences with the criminal justice system are all highly patterned by race, with people of color experiencing more that is health harming. Finding ways to uncouple the link between race and access to resources and healthy environments is a principal means of reducing health disparities. Additionally, the anticipation of racism itself causes higher psychological and cardiovascular stress levels that are linked to poor health outcomes. Remedying discriminatory practices at the individual and systemic levels will likely reduce health disparities caused by this unequal distribution of stress. (v) Poor health among Native Americans has largely been driven by post-colonial
