Mental Health and Substance Use Among Black Women Attending STD Clinics in Baltimore: The Role of Overt and Subtle Discrimination.

Black women are disproportionately impacted by mental health conditions, like depression, posttraumatic stress disorder (PTSD), and substance use harms. Experiences of discrimination may cause and exacerbate these conditions, but little is known about how distinct types of discrimination (overt vs. subtle) may be related to these outcomes. The current study sought to evaluate the associations between overt and subtle discrimination, mental health, and substance misuse outcomes among Black women. Data were drawn from ESSENCE, a retrospective cohort study (2013-2018) on sexual assault and HIV risk among Black women attending sexually transmitted disease (STD) clinics in Baltimore, Maryland (n = 199). Multivariable Poisson regression models tested the associations between overt and subtle discrimination, depressive and PTSD symptoms, and substance misuse while controlling for covariates. Nearly half (42.2%) of participants reported depressive symptoms, and over a third reported severe PTSD symptoms (35.2%). Higher levels of subtle discrimination were associated with increased risk of depressive symptoms (adjusted relative risk [aRR] = 1.32, 95% confidence interval [CI]: 1.16, 1.50, p < .0001), whereas higher levels of overt discrimination were associated with increased risk of severe PTSD symptoms (aRR = 1.22, 95% CI [1.02, 1.46], p = .0287). Neither overt nor subtle discrimination was significantly associated with hazardous alcohol use or daily marijuana use in adjusted models. We identified that subtle discrimination has a unique negative association with depressive symptoms, while overt discrimination is positively associated with PTSD symptoms. This information is critical for tailoring stigma reduction interventions and mental health supports for Black women.
