Over the last decades, public health departments have been moving their practice further and further upstream to address the root causes of health inequities. This evolution, from a focus on behaviors to a focus on the social determinants of health, has most recently led to health departments taking action on the root of the root causes: power. Simply put, power, is a driver of our class, racial, and gender structures. Public health research shows us clearly that the degree of power and control we have as individuals and communities has a direct impact on our health outcomes. And that power concentrated in the hands of a few, with the inequality that follows, hurts the health of everyone in our society, of every racial group, class, gender, and identity.
