The unique contribution of gendered racial stress to depressive symptoms among pregnant Black women

Introduction: Pregnant Black women are at disproportionate risk for adverse birth outcomes, in part associated with higher prevalence of stress. Stress increases risk of depression, a known risk factor for preterm birth. In addition, multiple dimensions of stress, including perceived stress and stressful life events, are associated with adverse birth outcomes, independent of their association with prenatal depression. We use an intersectional and contextualized measure of gendered racial stress to assess whether gendered racial stress constitutes an additional dimension to prenatal depression, independent of stressful life events and perceived stress. Methods: In this cross-sectional study of 428 Black women, we assessed gendered racial stress (using the 39-item Jackson Hogue Phillips Reduced Common Contextualized Stress Measure), perceived stress (using the Perceived Stress Scale), and stressful life events (using a Stressful Life Event Index) as psychosocial predictors of depressive symptoms (measured by the Edinburgh Depression Scale). We used bivariate analyses and multivariable regression to assess the association between the measures of stress and prenatal depression. Results: Results revealed significant bivariate associations between participant scores on the full Jackson Hogue Phillips Reduced Common Contextualized Stress Measure and its 5 subscales, and the Edinburgh Depression Scale. In multivariable models that included participant Perceived Stress Scale and/or Stressful Life Event Index scores, the Jackson Hogue Phillips Reduced Common Contextualized Stress Measure contributed uniquely and significantly to Edinburgh Depression Scale score, with the burden subscale being the strongest contributor among all variables. No sociodemographic characteristics were found to be significant in multivariable models. Conclusion: For Black women in early pregnancy, gendered racial stress is a distinct dimension of stress associated with increased depressive symptoms. Intersectional stress measures may best uncover nuances within Black women's complex social environment.
