Exposure to a greater number of adverse childhood experiences (ACEs) may accelerate biological aging in older adults, a McMaster University study has found.

The research was published online in the journal Aging Cell.

The study analyzed data from 1,445 participants aged 45 to 85 years from the Canadian Longitudinal Study on Aging. The participants provided blood samples for DNA methylation analysis and completed a self-report questionnaire on ACEs. These experiences include childhood exposure to physical, emotional or sexual abuse, neglect, as well as exposure to parental intimate partner violence or poor parental mental health.
