Maternal and Paternal Adverse Childhood Experiences (ACEs) and Offspring Health and Wellbeing: A Scoping Review

Adverse childhood experiences (ACEs) are common, often co-occur, and are associated with poor health outcomes across the life course. Emerging research has emphasized the lasting consequences of ACEs across generations, suggesting parental ACEs are associated with poor physical and mental health outcomes in children. However, the individual effects of fathers' ACEs and pathways of transmission remain unclear. A scoping review was conducted to summarize the current knowledgebase of the intergenerational consequences of parental ACEs on offspring health, clarify pathways of transmission, understand how ACEs are operationalized in the intergenerational literature, and identify gaps in knowledge.

Six electronic databases were searched for articles published in English from 1995 to 2022 relating to the long-term consequences of parental ACEs on offspring physical and mental health. Articles underwent title, abstract, and full-text review by two investigators. Content analysis was performed to integrate findings across the included studies.

The search yielded 14,542 unique articles; 49 met the inclusion criteria. Thirty-six articles focused exclusively on mothers, one solely on fathers, and 12 included both mothers and fathers in their analyses. Six studies used an expanded definition of ACEs. Both direct and indirect associations between parental ACEs and poor offspring outcomes were identified, primarily through biological and psychosocial pathways.

Findings underscore the importance and oversight of fathers and the need to solidify a unified definition and measure of ACEs. This review identified modifiable protective factors (social support, father involvement) and pathways of transmission (parental mental health, parenting); both having important implications for intervention development.
