Epigenetics, maternal prenatal psychosocial stress, and infant mental health.

This paper provides a summary of literature on epigenetic effects and infant health outcomes of maternal psychosocial stress during pregnancy. A search of literature yielded a large body of publications between 2008 and 2018. Relevant articles were selected, and additional sources were located from ancestry searches of reference lists. Results implicate maternal prenatal stress as a source of epigenetic mechanisms that affect fetal brain development and program risk for emotional dysregulation and mental disorders over a lifetime and across generations. Implications for nursing practice are explored at multiple levels of policy advocacy, public education, primary prevention, screening and intervention.
