AbstractBackground: Allostatic load is the physiological deterioration that accumulates as the body responds to stress, resulting in disparities in chronic disease. Although perceptions of stress vary, marginalization and social disadvantage are associated with elevated allostatic load. Allostatic load is understudied in the multiply marginalized populations of sexual minority Black women. Methods: We used data from six waves of the National Health and Nutrition Examination Survey (2001-2010, 2015-2016) to identify heterosexual (n = 78), lesbian (n = 21), and bisexual (n = 57) Black women. We quantified allostatic load using nine biomarkers, and compared mean allostatic load across the three groups, adjusting for age, educational attainment, income, and country of birth to account for possible confounding. Results: We found no significant differences in allostatic load among heterosexual, lesbian, and bisexual Black women. Conclusions: These findings suggest that sexual orientation may not contribute to within-group differences in allostatic load among Black women, a group previously noted to have elevated allostatic load.
