Integrating the Neurobiology of Minority Stress with an Intersectionality Framework for LGBTQ‐Latinx Populations

The comprehensive lived experiences of lesbian, gay, bisexual, transgender, and queer (LGBTQ) individuals of color remain invisible in neurobiological studies of LGBTQ populations. Models of minority stress posit that LGBTQ and Latinx individuals experience and internalize sexual, ethnic, racial, and gender discrimination, which may adversely impact mental and physical health. However, the current minority stress models predominantly focus on single categorical social identities and do not account for interlocking systems and processes of oppression based on features of sexuality, race, ethnicity, sex, and gender, as explained by an intersectionality framework in feminist theory. Thus, it remains unclear how LGBTQ people of color internalize and navigate multiple cultural, institutional, and societal stressors, and, furthermore, how these sources of stress may affect health and well-being. A potential mechanism for this adverse internalization process is through the effects of stress on neurobiological regulation. This review will apply an intersectionality framework to the examination of how heterosexism, racism, and cissexism, as systems of oppression, create LGBTQ and Latinx lived experiences, and the differential impacts of these inequalities on neurobiological stress regulation. The overarching goal of this manuscript is to advocate for the application of intersectionality theory to advance the ecological validity of biopsychosocial models of multiple-minority stress
