Ethnic–racial discrimination, the differential treatment of individuals based on ethnic or racial group membership, predicts poor mental health outcomes such as anxiety. This is supported by long-standing theories on the social determinants of health and minority stress. However, these theories are rarely expanded to neurobiological sciences, limiting our understanding of mechanisms underlying observed associations. One potential neurobiological pathway between ethnic–racial discrimination exposure and anxiety is that ongoing exposure to racially charged encounters presents imminent threats that may modify stress-sensitive neurocircuitry, like the amygdala.
The current study evaluated whether amygdala volume mediated associations between ethnic–racial discrimination exposure and anxiety symptoms in Latina girls, a group exhibiting heightened levels of untreated anxiety and disproportionately subjected to ethnic–racial discrimination.
Thirty predominantly Mexican-identifying Latina girls residing in Southern California (
