Abstract
Exposure to pervasive racial discrimination of Black Americans is transgenerational in that mothers' experiences of discriminatory violence impacts their children. This study explored whether stress-related biomarkers reflect transgenerational racial stress by implementing a "dual activation" framework to probe how adrenal and gonadal hormones underlying adolescent development are co-regulated during a laboratory stressor. Data were collected from 120 Black families in the United States. Children completed the Trier Social Stress Task (TSST-C) and provided 4 saliva samples across 2 days that were assayed for cortisol (C), dehydroepiandrosterone (DHEA), and testosterone (T). Mothers reported their experiences of total discrimination and racial discrimination related to skin color/race. Thirty four percent reported experiences of discrimination and on average 46.7% reported experiences of discrimination due to their race or skin tone. Mothers' experiences of racial discrimination were associated with their child's hormonal reactivity to and recovery from the TSST-C. Youth showed stronger positive hormone coupling between C-T if their mother experienced greater discrimination. Mothers' experiences of racial discrimination influenced both C-T coupling and youths' cortisol recovery from the TSST-C. For youths with high testosterone, cortisol recovery was blunted. Results suggest that associations between racism and hormonal stress response may be transgenerational. Mothers' experiences of discrimination had a profound impact on their children's hormonal co-regulation.
