: Articulating foundational principles for research in partnership with bisexual communities.

Bisexual people comprise over half of all adults who identify as sexual minorities within the United States. Increasingly, population level health research has revealed that bisexual people face striking and broad-ranging health disparities compared not only to heterosexual people, but also often compared to their gay and lesbian peers. Despite the fact that bisexual people comprise an 'invisible majority' of LGBTQ people and are disproportionately impacted by poor health, the vast majority of funding dedicated to LGBTQ community organizing and to sexual and gender minority health research does not address the needs of bisexual people. Within this three-part article, we first describe how manifestations of systematic biphobia have led to the current situation where bisexual community organizations and bisexual health researchers are not granted adequate resources to address the health and health promotion of bisexual populations. In the second section, we articulate foundational ethical guiding principles and propose , a new model to inform the design, evaluation, and implementation of intersectional bisexual community engaged research to inform the development of structural bisexual-specific health equity interventions. In the last section of this paper, we present the Chicago Bisexual Health Task Force as a case study of the model in action to illustrate a real-life approach that community engaged research and advocacy initiatives can take to promote bisexual health equity. We view this article as an invitation for dialogue about how to develop best practices to advance bisexual health equity and hope that it inspires additional bisexual people, organizers, and researchers to join in these pursuits.
