Title: advancing urban health equity in the United States in an age of health care gentrification: a framework and research agenda.

We describe the concept of health care gentrification, and the complex ways in which both neighborhood gentrification and health care gentrification may lead to inequitable access to health care. We then present a framework for understanding health care gentrification as a function of dynamic and multi-level systems, and propose ways to build on existing models of health care access and social determinants of health to more effectively measure and address this phenomenon. Finally, we describe potential strategies applied researchers might investigate that could prevent or remediate the effects of health care gentrification in the United States.
