Abstract
Objective
Adverse childhood experiences (ACEs) are associated with increased risk of premature mortality, but it is not clear why. Individuals with ACEs tend to have lower self-acceptance and purpose in life, which may be pathways between ACEs and risk of premature mortality. As such, we tested whether purpose and self-acceptance are mechanisms that link ACEs to mortality risk.
Methods
We used the Midlife in the United States Survey (N = 6218; M ± SD = 46.89 ± 12.94 years) to test whether these factors were indirect pathways (mediated) the association between ACEs and mortality hazards over 24 years of follow-up. We employed a comprehensive ACEs measure that included 20 possible childhood adversities including emotional and physical abuse, household instability, socioeconomic climate, and ill health.
Results
ACEs significantly increased mortality risk, HR = 1.028, 95% CI (1.008, 1.047), p = 0.006. Self-acceptance and purpose accounted for an estimated 15% and 4% of the ACEs-mortality relation respectively. These effects withstood a range of adjustments and sensitivity analyses.
Conclusions
ACEs may impact mortality risk partially through lower self-acceptance and purpose during adulthood. Given that self-acceptance and purpose may change through intervention, these factors may be useful targets for individuals with ACEs that could lead to a longer life.
