Discrimination linked to accelerated biological aging

May 9 2024New York University

Research shows that people who experience discrimination based on their identity are at increased risk for a range of health issues, including heart disease, high blood pressure, and depression. While the precise biological factors driving these poor health outcomes are not fully understood, chronic activation of the body's stress response is a likely contributor. Moreover, a growing body of research connects persistent exposure to discrimination to the biological processes of aging.

The researchers found that discrimination was linked to accelerated biological aging, with people who reported more discrimination aging faster biologically compared to those who experienced less discrimination. Everyday and major discrimination were consistently associated with biological aging, while exposure to discrimination in the workplace was also linked to accelerated aging, but its impact was comparatively less severe.

In addition, the link between discrimination and accelerated biological aging varied by race. Black study participants reported more discrimination and tended to exhibit older biological age and faster biological aging. However, White participants, who reported less discrimination, were more susceptible to the impacts of discrimination when they did experience it, perhaps due to less frequent exposure and fewer coping strategies.
