Understanding the Association Between Medical Mistrust and Unmet Medical Care Need in Gender and Sexually Diverse People of Color Assigned Female at Birth

<b><i>Purpose:</i></b> The present study investigated associations of sexual orientation and/or gender identity-based medical mistrust and racial/ethnic-based medical mistrust, respectively, with unmet medical care need among lesbian, gay, bisexual, transgender, queer, and/or sexually or gender diverse (LGBTQ+) people of color (POC) assigned female at birth (AFAB). We also tested the interaction of the two types of medical mistrust on unmet medical care need. <b><i>Methods:</i></b> Participants were 266 LGBTQ+ POC AFAB. Participants completed measures of medical mistrust based on race/ethnicity and LGBTQ+ identity. Unmet medical care need was assessed using the item: "During the past 12 months, was there ever a time where you felt that you needed health care but you didn't receive it?" Multivariate logistic regression models were run with either type of medical mistrust, as well as their interaction, as the predictor and unmet medical care need as the outcome variable. <b><i>Results:</i></b> There were no significant main effects of either type of medical mistrust on unmet medical care need. However, there was an interaction between the two types of medical mistrust, such that associations between each type of medical mistrust and unmet medical care needs were stronger at higher levels of the other type of medical mistrust. Racial/ethnic medical mistrust was associated with a greater likelihood of unmet medical needs at high, but not low, levels of LGBTQ+ medical mistrust. <b><i>Conclusions:</i></b> Racial/ethnic medical mistrust and LGBTQ+ medical mistrust exacerbate each other's influence on unmet medical care need. These results underscore the need for inclusive clinical practices for LGBTQ+ POC.
