Purpose: We examined the association of psychosocial stressors (depressive symptoms, incarceration, and intimate partner violence [IPV]) with sexual behaviors, sexually transmitted infection (STI) history, and STI diagnoses among African American women who have sex with women (AAWSW). Methods: This was a secondary analysis from a study of AAWSW ≥16 years. Multivariable Poisson regression estimated risk ratios (RRs) for the association between depressive symptoms, incarceration, and IPV and sexual behaviors, STI history, and STI diagnosis at enrollment, adjusting for age and sexual orientation identity. Results: Of 165 AAWSW, the mean depressive symptom score was 1.0 (SD ±0.8); 22.4% reported incarceration and 62.4% reported IPV. Depressive symptoms were associated with alcohol/drug use at last sexual encounter (RR = 1.52, 95% confidence interval [CI]: 1.18-1.95) and STI diagnosis (RR = 1.19; 95% CI: 1.05-1.34). Incarceration was associated with STI history (RR = 1.28; 95% CI: 1.07-1.53). IPV was associated with alcohol/drug use during sex with women (RR = 1.42; 95% CI: 1.05-1.92) and STI history (RR = 1.42, 95% CI: 1.13-1.78), particularly trichomoniasis (RR 2.50; 95% CI: 1.52-4.12). Among AAWSW reporting sex with men (n = 144), depressive symptoms were associated with sex in exchange for money/drugs (RR = 1.98; 95% CI: 1.17-3.34) and alcohol/drug use during sex with men (RR = 1.24; 95% CI: 1.05-1.46). Incarceration was associated with sex in exchange for money/drugs with men (RR = 5.21; 95% CI: 1.86-14.57); IPV was associated with sex in exchange for money/drugs (RR = 5.04; 95% CI: 1.18-21.50) and alcohol/drug use during sex with men (RR = 1.66; 95% CI: 1.14-2.41). Conclusion: Providers and public health programs should address both psychosocial stressors and STI risk among AAWSW.
