Transgenerational Inheritance and Systemic Racism in America.

Objective: It is well established that personal experiences of trauma, adversity, and discrimination can "get under the skin" and increase risk for a whole host of negative mental and physical health outcomes. The aim of this article is to review emerging research on transgenerational epigenetic inheritance which suggests that negative exposures in one generation, can also be passed down to affect the health and well-being of future generations.

Method: This paper reviews key concepts in transgenerational epigenetic inheritance research, select animal and human studies examining the role of epigenetic mechanisms in transmitting the impact of ancestral stress and trauma, poor nutrition, and toxicant exposure across generations, and factors that can mitigate the effects of these experiences.
