Central Hemodynamics in African American Women: Examining the Role of Superwoman Schema Endorsement

Abstract

Background African American women bear a disproportionate burden of cardiovascular diseases, potentially due to altered central hemodynamics. Racism and sexism often lead to African American women taking on numerous caretaking roles and overall increases their use of the Strong Black Woman (ie, Superwoman) mindset, which may have negative health consequences. We hypothesized that endorsing the Superwoman role and its Obligation to Help Others dimension would be associated with a deleterious central hemodynamics profile in African American women. Methods and Results Using cross‐sectional data, we examined central systolic blood pressure (mm Hg; n=408), augmentation index (percentage, adjusted for height and heart rate; n=408), and pulse wave velocity (m/s; n=368) in African American women aged 30 to 46 years. The Giscombe Superwoman Schema (SWS) questionnaire assessed endorsement of Overall SWS (range, 0–105) and SWS–Obligation to Help Others (range, 0–3). Multiple linear regression modeled associations between Overall SWS (10‐unit increments) and SWS–Obligation to Help Others (1‐unit increments) and central hemodynamics while adjusting for pertinent sociodemographic, clinical, and psychosocial factors. In fully adjusted models, central systolic blood pressure was significantly associated with Overall SWS (β=0.83 [95% CI, 0.19–1.47]) and SWS–Obligation to Help Others (β=2.03 [95% CI, 0.39–3.67]). Augmentation index was associated with Overall SWS (β=0.66 [95% CI, 0.02–1.30]) and SWS–Obligation to Help Others (β=2.21 [95% CI, 0.58–3.84]). Significant associations were not observed between pulse wave velocity and SWS. Conclusions Greater endorsement of the Superwoman role and prioritizing caregiving over self‐care were associated with higher central systolic blood pressure and augmentation index, which may contribute to adverse cardiovascular health among African American women.
