Transformation for health: A framework for health disparities research

The task of generating knowledge addressing disparities in health among vulnerable populations in American society is explored. The community-based participatory approach as an alternate paradigm to traditional research is mentioned as a process for understanding the realities of the populations of interest. Identification and testing of mediating and moderating variables is suggested to guide the process of increasing knowledge regarding health disparities. Transformation for Health is proposed as a conceptual framework to study how these third variables influence the relationship between the primary variables of interest. A theoretical example is offered describing the application of the framework to study the mediators and moderators in an investigation of childhood obesity. Analytical challenges in the exploration of “third variables” are described, and the authors recommend that salient methodological issues should be addressed when conducting these types of investigations.
